1 # NEWS for rsync 3.2.5 (UNRELEASED)
3 ## Changes in this version:
7 - Added some file-list safety checking that helps to ensure that a rogue
8 sending rsync can't add unrequested top-level names and/or include recursive
9 names that should have been excluded by the sender. These extra safety
10 checks only require the receiver rsync to be updated. When dealing with an
11 untrusted sending host, it is safest to copy into a dedicated destination
12 directory for the remote content (i.e. don't copy into a destination
13 directory that contains files that aren't from the remote host unless you
14 trust the remote host). Fixes CVE-2022-29154.
16 - A fix for CVE-2022-37434 in the bundled zlib (buffer overflow issue).
20 - Fixed the configure check for signed char that was causing a host that
21 defaults to unsigned characters to generate bogus rolling checksums. This
22 made rsync send mostly literal data for a copy instead of finding matching
23 data in the receiver's basis file (for a file that contains high-bit
26 - Lots of manpage improvements, including an attempt to better describe how
27 include/exclude filters work.
29 ### PACKAGING RELATED:
31 - The build date that goes into the manpages is now based on the developer's
32 release date, not on the build's local-timezone interpretation of the date.
34 ### DEVELOPER RELATED:
36 - Configure now defaults GETGROUPS_T to gid_t when cross compiling.
38 - Configure now looks for the bsd/string.h include file in order to fix the
39 build on a host that has strlcpy() in the main libc but not defined in the

44 # NEWS for rsync 3.2.4 (15 Apr 2022)
46 ## Changes in this version:
50 - A new form of arg protection was added that works similarly to the older
51 [`--protect-args`](rsync.1#opt) (`-s`) option but in a way that avoids
52 breaking things like rrsync (the restricted rsync script): rsync now uses
53 backslash escaping for sending "shell-active" characters to the remote
54 shell. This includes spaces, so fetching a remote file via a simple quoted
55 filename value now works by default without any extra quoting:
58 rsync -aiv host:'a simple file.pdf' .
61 Wildcards are not escaped in filename args, but they are escaped in options
62 like the [`--suffix`](rsync.1#opt) and [`--usermap`](rsync.1#opt) values.
63 If your rsync script depends on the old arg-splitting behavior, either run
64 it with the [`--old-args`](rsync.1#opt) option or `export RSYNC_OLD_ARGS=1`
65 in the script's environment. See also the [ADVANCED USAGE](rsync.1#)
66 section of rsync's manpage for how to use a more modern arg style.
68 - A long-standing bug was preventing rsync from figuring out the current
69 locale's decimal point character, which made rsync always output numbers
70 using the "C" locale. Since this is now fixed in 3.2.4, a script that
71 parses rsync's decimal numbers (e.g. from the verbose footer) may want to
72 setup the environment in a way that the output continues to be in the C
73 locale. For instance, one of the following should work fine:
79 or if iconv translations are needed:
82 if [ "${LC_ALL:-}" ]; then
84 export LC_CTYPE="$LC_ALL"
87 export LC_NUMERIC=C.UTF-8
92 - A fix for CVE-2018-25032 in the bundled zlib (memory corruption issue).
96 - Fixed a bug with [`--inplace`](rsync.1#opt) + [`--sparse`](rsync.1#opt) (and
97 a lack of [`--whole-file`](rsync.1#opt)) where the destination file could
98 get reconstructed with bogus data. Since the bug can also be avoided by
99 using (the seemingly redundant) [`--no-W`](rsync.1#opt) on the receiving
100 side, the latest rsync will now send `--no-W` to a remote receiver when this
101 option combination occurs. If your client rsync is not new enough to do
102 this for you (or if you're just paranoid), you can manually specify `--no-W
103 -M--no-W` (when not using [`--whole-file`](rsync.1#opt)) to make sure the
106 - Fixed a bug with [`--mkpath`](rsync.1#opt) if a single-file copy specifies
107 an existing destination dir with a non-existing destination filename.
109 - Fixed `--update -vv` to output "is uptodate" instead of "is newer" messages
110 for files that are being skipped due to an identical modify time. (This was
111 a new output quirk in 3.2.3.)
113 - When doing an append transfer, the sending side's file must not get shorter
114 or it is skipped. Fixes a crash that could occur when the size changes to 0
115 in the middle of the send negotiations.
117 - When dealing with special files (see [`--specials`](rsync.1#opt)) in an
118 alt-dest hierarchy, rsync now checks the non-permission mode bits to ensure
119 that the 2 special files are really the same before hard-linking them
122 - Fixed a bug where [`--delay-updates`](rsync.1#opt) with stale partial data
123 could cause a file to fail to update.
125 - Fixed a few places that would output an INFO message with
126 [`--info=NAME`](rsync.1#opt) that should only have been output given
127 [`--verbose`](rsync.1#opt) or [`--itemize-changes`](rsync.1#opt).
129 - Avoid a weird failure if you run a local copy with a (useless)
130 [`--rsh`](rsync.1#opt) option that contains a `V` in the command.
132 - Fixed a long-standing compression bug where the compression level of the
133 first file transferred affected the level for all future files. Also, the
134 per-file compression skipping has apparently never worked, so it is now
135 documented as being ineffective.
137 - Fixed a truncate error when a `--write-devices` copy wrote a file onto a
138 device that was shorter than the device.
140 - Made `--write-devices` support both `--checksum` and `--no-whole-file` when
143 - Improved how the [`--stop-at`](rsync.1#opt), [`--stop-after`](rsync.1#opt),
144 and (the deprecated) [`--time-limit`](rsync.1#opt) options check to see if
145 the allowed time is over, which should make rsync exit more consistently.
147 - Tweak --progress to display "`??:??:??`" when the time-remaining value is so
148 large as to be meaningless.
150 - Silence some chmod warnings about symlinks when it looks like we have a
151 function to set their permissions but they can't really be set.
153 - Fixed a potential issue in git-set-file-times when handling commits with
154 high-bit characters in the description & when handling a description that
155 might mimick the git raw-commit deliniators. (See the support dir.)
157 - The bundled systemd/rsync.service file now includes `Restart=on-failure`.
161 - Use openssl's `-verify_hostname` option in the rsync-ssl script.
163 - Added extra info to the "FILENAME exists" output of
164 [`--ignore-existing`](rsync.1#opt) when [`--info=skip2`](rsync.1#opt) is
165 used. The skip message becomes "FILENAME exists (INFO)" where the INFO is
166 one of "type change", "sum change" (requires [`--checksum`](rsync.1#opt)),
167 "file change" (based on the quick check), "attr change", or "uptodate".
168 Prior versions only supported `--info=skip1`.
170 - Added the [`--fsync`](rsync.1#opt) option (promoted from the patches repo).
172 - Added the [`--copy-devices`](rsync.1#opt) option. Compared to the
173 historical version from the rsync-patches repo, this version: properly
174 handles `--checksum`; fixes a truncation bug when doing an `--inplace` copy
175 onto a longer file; fixes several bugs in the `--itemize` output; and only
176 the sending side needs the enhanced rsync for the copy to work.
178 - Reduced memory usage for an incremental transfer that has a bunch of small
181 - The rsync daemon can now handle a client address with an implied "%scope"
184 - Added support for [`--atimes`](rsync.1#opt) on macOS and fixed a bug where
185 it wouldn't work without [`--times`](rsync.1#opt).
187 - Rsync can now update the xattrs on a read-only file when your user can
188 temporarily add user-write permission to the file. (It always worked for a
191 - Rsync can now work around an [`--inplace`](rsync.1#opt) update of a file
192 that is being refused due to the Linux fs.protected_regular sysctl setting.
194 - When [`--chown`](rsync.1#opt), [`--usermap`](rsync.1#opt), or
195 [`--groupmap`](rsync.1#opt) is specified, rsync now makes sure that the
196 appropriate [`--owner`](rsync.1#opt) and/or [`--group`](rsync.1#opt) options
199 - Added the [`--info=NONREG`](rsync.1#opt) setting to control if rsync should
200 warn about non-regular files in the transfer. This is enabled by default
201 (keeping the behavior the same as before), so specifying `--info=nonreg0`
202 can be used to turn the warnings off.
204 - An optional asm optimization for the rolling checksum from Shark64. Enable
205 it with `./configure --enable-roll-asm`.
207 - Using `--debug=FILTER` now outputs a caution message if a filter rule
208 has trailing whitespace.
210 - Transformed rrsync into a python script with improvements:
211 - Security has been beefed up.
212 - The known rsync options were updated to include recent additions.
213 - Make rrsync reject [`--copy-links`](rsync.1#opt) (`-L`),
214 [`--copy-dirlinks`](rsync.1#opt) (`-k`), &
215 [`--keep-dirlinks`](rsync.1#opt) (`-K`) by default to make it harder to
216 exploit any out-of-subdir symlinks.
217 - A new rrsync option of [`-munge`](rrsync.1#opt) tells rrsync to always
218 enable rsync's [`--munge-links`](rsync.1#opt) option on the server side.
219 - A new rrsync option of [`-no-lock`](rrsync.1#opt) disables a new
220 single-use locking idiom that is the default when [`-ro`](rrsync.1#opt) is
221 not used (useful with [`-munge`](rrsync.1#opt)).
222 - A new rrsync option of [`-no-del`](rrsync.1#opt) disables all `--remove*`
223 and `--delete*` rsync options on the server side.
224 - The log format has been tweaked slightly to add seconds to the timestamp
225 and to output the command executed as a tuple (making the args clearer).
226 - An rrsync.1 manpage was added (in the support dir with rrsync).
228 - Added options to the lsh script to facilitate rrsync testing. (See the
231 - Transformed the atomic-rsync script into a python script and added the
232 ability to ignore one or more non-zero exit codes. By default, it now
233 ignores code 24, the file-vanished exit code. (See the support dir.)
235 - Transformed the munge-symlinks script into python. (See the support dir.)
237 - Improved the rsync-no-vanished script to not join stdout & stderr together.
238 (See the support dir.)
240 - Work around a glibc bug where lchmod() breaks in a chroot w/o /proc mounted.
242 - Try to support a client that sent a remote rsync a wacko stderr file handle
243 (such as an older File::RsyncP perl library used by BackupPC).
245 - Lots of manpage improvements, including better HTML versions.
247 ### PACKAGING RELATED:
249 - Give configure the `--with-rrsync` option if you want `make install` to
250 install the (now python3) rrsync script and its new manpage.
252 - If the rrsync script is installed, its package should be changed to depend
253 on python3 and the (suggested but not mandatory) python3 braceexpand lib.
255 - When creating a package from a non-release version (w/o a git checkout), the
256 packager can elect to create git-version.h and define RSYNC_GITVER to the
257 string they want `--version` to output. (The file is still auto-generated
258 using the output of `git describe` when building inside a non-shallow git
261 - Renamed configure's `--enable-simd` option to `--enable-roll-simd` and added
262 the option `--enable-roll-asm` to use the new asm version of the code. Both
263 are x86_64/amd64 only.
265 - Renamed configure's `--enable-asm` option to `--enable-md5-asm` to avoid
266 confusion with the asm option for the rolling checksum. It is also honored
267 even when openssl crypto is in use. This allows: normal MD4 & MD5, normal
268 MD4 + asm MD5, openssl MD4 & MD5, or openssl MD4 + asm MD5 depending on the
269 configure options selected.
271 - Made SIMD & asm configure checks default to "no" on non-Linux hosts due to
272 various reports of problems on NetBSD & macOS hosts. These were also
273 tweaked to allow enabling the feature on a host_cpu of amd64 (was only
274 allowed on x86_64 before).
276 - Fixed configure to not fail at the SIMD check when cross-compiling.
278 - Improved the IPv6 determination in configure.
280 - Compile the C files with `-pedantic-errors` (when possible) so that we will
281 get warned if a static initialization overflows in the future (among other
284 - When linking with an external zlib, rsync renames its `read_buf()` function
285 to `read_buf_()` to avoid a symbol clash on an unpatched zlib.
287 - Added a SECURITY.md file.
289 ### DEVELOPER RELATED:
291 - Made it easier to write rsync tests that diff the output while also checking
292 the status code, and used the idiom to improve the existing tests. (See the
293 `checkdiff` and `checkdiff2` idioms in the `testsuite/*.test` files.
295 - The packaging scripts & related python lib got some minor enhancements.
299 - Use setenv() instead of putenv() when it is available.
301 - Improve the logic in compat.c so that we don't need to try to remember to
302 sprinkle `!local_server` exceptions throughout the protocol logic.
304 - One more C99 Flexible Array improvement (started in the last release) and
305 make use of the C99 `%zd` format string when printing size_t values (when
308 - Use mallinfo2() instead of mallinfo(), when available.
310 ------------------------------------------------------------------------------
312 # NEWS for rsync 3.2.3 (6 Aug 2020)
314 ## Changes in this version:
318 - Fixed a bug in the xattr code that was freeing the wrong object when trying
319 to cleanup the xattr list.
321 - Fixed a bug in the xattr code that was not leaving room for the "rsync."
322 prefix in some instances where it needed to be added.
324 - Restored the ability to use [`--bwlimit=0`](rsync.1#opt) to specify no
325 bandwidth limit. (It was accidentally broken in 3.2.2.)
327 - Fixed a bug when combining [`--delete-missing-args`](rsync.1#opt) with
328 [`--no-implied-dirs`](rsync.1#opt) & [`-R`](rsync.1#opt) where rsync might
329 create the destination path of a missing arg. The code also avoids some
330 superfluous warnings for nested paths of removed args.
332 - Fixed an issue where hard-linked devices could cause the rdev_major value to
333 get out of sync between the sender and the receiver, which could cause a
334 device to get created with the wrong major value in its major,minor pair.
336 - Rsync now complains about a missing [`--temp-dir`](rsync.1#opt) before
337 starting any file transfers.
339 - A completely empty source arg is now a fatal error. This doesn't change
340 the handling of implied dot-dir args such as "localhost:" and such.
344 - Allow [`--max-alloc=0`](rsync.1#opt) to specify no limit to the alloc sanity
347 - Allow [`--block-size=SIZE`](rsync.1#opt) to specify the size using units
350 - The name of the id-0 user & group are now sent to the receiver along with
351 the other user/group names in the transfer (instead of assuming that both
352 sides have the same id-0 names).
354 - Added the [`--stop-after`](rsync.1#opt) and [`--stop-at`](rsync.1#opt)
355 options (with a [`--time-limit`](rsync.1#opt) alias for `--stop-after`).
356 This is an enhanced version of the time-limit patch from the patches repo.
358 - Added the [`name converter`](rsyncd.conf.5#opt) daemon parameter to make it
359 easier to convert user & group names inside a chrooted daemon module. This
360 is based on the nameconverter patch with some improvements, including a
361 tweak to the request protocol (so if you used this patch in the past, be
362 sure to update your converter script to use newlines instead of null chars).
364 - Added [`--crtimes`](rsync.1#opt) (`-N`) option for preserving the file's
365 create time (I believe that this is macOS only at the moment).
367 - Added [`--mkpath`](rsync.1#opt) option to tell rsync that it should create a
368 non-existing path component of the destination arg.
370 - Added [`--stderr=errors|all|client`](rsync.1#opt) to replace the
371 `--msgs2stderr` and `--no-msgs2stderr` options (which are still accepted).
372 The default use of stderr was changed to be `--stderr=errors` where all the
373 processes that have stderr available output directly to stderr, which should
374 help error messages get to the user more quickly, especially when doing a
375 push (which includes local copying). This also allows rsync to exit quickly
376 when a receiver failure occurs, since rsync doesn't need to try to keep the
377 connection alive long enough for the fatal error to go from the receiver to
378 the generator to the sender. The old default can be requested via
379 `--stderr=client`. Also changed is that a non-default stderr mode is
380 conveyed to the remote rsync (using the older option names) instead of
381 requiring the user to use [`--remote-option`](rsync.1#opt) (`-M`) to tell
382 the remote rsync what to do.
384 - Added the ability to specify "@netgroup" names to the [`hosts
385 allow`](rsyncd.conf.5#opt) and [`hosts deny`](rsyncd.conf.5#opt) daemon
386 parameters. This is a finalized version of the netgroup-auth patch from the
389 - Rsync can now hard-link symlinks on FreeBSD due to it making use of the
390 linkat() function when it is available.
392 - Output file+line info on out-of-memory & overflow errors while also avoiding
393 the output of alternate build-dir path info that is not useful to the user.
395 - Change configure to know that Cygwin supports Linux xattrs.
397 - Improved the testsuite on FreeBSD & Cygwin.
399 - Added some compatibility code for HPE NonStop platforms.
401 - Improved the INSTALL.md info.
403 - Added a few more suffixes to the default skip-compress list.
405 - Improved configure's error handling to notify about several issues at once
406 instead of one by one (for the newest optional features).
410 - Use a simpler overflow check idiom in a few spots.
412 - Use a C99 Flexible Array for a trailing variable-size filename in a struct
413 (with a fallback to the old 1-char string kluge for older compilers).
415 ------------------------------------------------------------------------------
417 # NEWS for rsync 3.2.2 (4 Jul 2020)
419 ## Changes in this version:
423 - Avoid a crash when a daemon module enables `transfer logging` without
424 setting a `log format` value.
426 - Fixed installing rsync-ssl script from an alternate build dir.
428 - Fixed the updating of configure.sh from an alternate build dir.
430 - Apple requires the asm function name to begin with an underscore.
432 - Avoid a test failure in the daemon test when `--atimes` is disabled.
436 - Allow the server side to restrict checksum & compression choices via the
437 same environment variables the client uses. The env vars can be divided
438 into "client list & server list" by the "`&`" char or the same list can
441 - Simplify how the negotiation environment variables apply when interacting
442 with an older rsync and also when a list contains only invalid names.
444 - Do not allow a negotiated checksum or compression choice of "none" unless
445 the user authorized it via an environment variable or command-line option.
447 - Added the `--max-alloc=SIZE` option to be able to override the memory
448 allocator's sanity-check limit. It defaults to 1G (as before) but the error
449 message when exceeding it specifically mentions the new option so that you
450 can differentiate an out-of-memory error from a failure of this limit. It
451 also allows you to specify the value via the RSYNC_MAX_ALLOC environment
454 - Add the "open atime" daemon parameter to allow a daemon to always enable or
455 disable the use of O_NOATIME (the default is to let the user control it).
457 - The default systemd config was changed to remove the `ProtectHome=on`
458 setting since rsync is often used to serve files in /home and /root and this
459 seemed a bit too strict. Feel free to use `systemctl edit rsync` to add
460 that restriction (or maybe `ProtectHome=read-only`), if you like. See the
461 3.2.0 NEWS for the other restrictions that were added compared to 3.1.3.
463 - The memory allocation functions now automatically check for a failure and
464 die when out of memory. This eliminated some caller-side check-and-die
465 code and added some missing sanity-checking of allocations.
467 - Put optimizations into their own list in the `--version` output.
469 - Improved the manpage a bit more.
471 ### PACKAGING RELATED:
473 - Prepared the checksum code for an upcoming xxHash release that provides new
474 XXH3 (64-bit) & XXH128 (128-bit) checksum routines. These will not be
475 compiled into rsync until the xxhash v0.8.0 include files are installed on
476 the build host, and that release is a few weeks away at the time this was
477 written. So, if it's now the future and you have packaged and installed
478 xxhash-0.8.0-devel, a fresh rebuild of rsync 3.2.2 will give you the new
479 checksum routines. Just make sure that the new rsync package depends on
482 ### DEVELOPER RELATED:
484 - Moved the version number out of configure.ac into its own version.h file so
485 that we don't need to reconfigure just because the version number changes.
487 - Moved the daemon parameter list into daemon-parm.txt so that an awk script
488 can create the interrelated structs and accessors that loadparm.c needs.
490 ------------------------------------------------------------------------------
492 # NEWS for rsync 3.2.1 (22 Jun 2020)
494 ## Changes in this version:
498 - Fixed a potential build issue with the MD5 assembly-language code by
499 removing some non-portable directives.
501 - Use the preprocessor with the asm file to ensure that if the code is
502 unneeded, it doesn't get built.
504 - Avoid the stack getting set to executable when including the asm code.
506 - Some improvements in the SIMD configure testing to try to avoid build
507 issues, such as avoiding a clang++ core dump when `-g` is combined with
508 `-O2`. Note that clang++ is quite buggy in this area, and it does still
509 crash for some folks, so just use `--disable-simd` if you need to avoid
510 their buggy compiler (since the configure test is apparently not finding
511 all the compilers that will to crash and burn).
513 - Fixed an issue in the md2man script when building from an alternate dir.
515 - Disable `--atimes` on macOS (it apparently just ignores the atime change).
519 - The use of `--backup-dir=STR` now implies `--backup`.
521 - Added `--zl=NUM` as a short-hand for `--compress-level=NUM`.
523 - Added `--early-input=FILE` option that allows the client to send some
524 data to a daemon's (optional) "early exec" script on its stdin.
526 - Mention atimes in the capabilities list that `--version` outputs.
528 - Mention either "default protect-args" or "optional protect-args" in the
529 `--version` capabilities depending on how rsync was configured.
531 - Some info on optimizations is now elided from the `--version` capabilities
532 since they aren't really user-facing capabilities. You can still see the
533 info (plus the status of a couple extra optimizations) by repeating the
534 `--version` option (e.g. `-VV`).
536 - Updated various URLs to be https instead of http.
538 - Some documentation improvements.
540 ### PACKAGING RELATED:
542 - If you had to use `--disable-simd` for 3.2.0, you might want to try removing
543 that and see if it will succeed or auto-disable. Some buggy clang++
544 compilers are still not auto disabled, though.
546 - The MD5 asm code is now under its own configure flag (not shared with the
547 SIMD setting), so if you have any issues compiling it, re-run configure with
550 - Merged the OLDNEWS.md file into NEWS.md.
552 ------------------------------------------------------------------------------
554 # NEWS for rsync 3.2.0 (19 Jun 2020)
556 ## Changes in this version:
560 - Avoid a potential out-of-bounds read in daemon mode if argc can be made to
563 - Fix the default list of skip-compress files for non-daemon transfers.
565 - Fix xattr filter rules losing an 'x' attribute in a non-local transfer.
567 - Avoid an error when a check for a potential fuzzy file happens to reference
570 - Make the atomic-rsync helper script have a more consistent error-exit.
572 - Make sure that a signal handler's use of exit_cleanup() calls `_exit()`
575 - Various zlib fixes, including security fixes for CVE-2016-9843,
576 CVE-2016-9842, CVE-2016-9841, and CVE-2016-9840.
578 - Fixed an issue with `--remove-source-files` not removing a source symlink
579 when combined with `--copy-links`.
581 - Fixed a bug where the daemon would fail to write early fatal error messages
582 to the client, such as refused or unknown command-line options.
584 - Fixed the block-size validation logic when dealing with older protocols.
586 - Some rrsync fixes and enhancements to handle the latest options.
588 - Fixed a problem with the `--link-dest`|`--copy-dest` code when `--xattrs`
589 was specified along with multiple alternate-destination directories (it
590 could possibly choose a bad file match while trying to find a better xattr
593 - Fixed a couple bugs in the handling of files with the `--sparse` option.
595 - Fixed a bug in the writing of the batch.sh file (w/`--write-batch`) when the
596 source & destination args were not last on the command-line.
598 - Avoid a hang when an overabundance of messages clogs up all the I/O buffers.
600 - Fixed a mismatch in the RSYNC_PID values put into the environment of
601 `pre-xfer exec` and a `post-xfer exec`.
603 - Fixed a crash in the `--iconv` code.
605 - Fixed a rare crash in the popt_unalias() code.
609 - The default systemd config was made stricter by default. For instance,
610 `ProtectHome=on` (which hides content in /root and /home/USER dirs),
611 `ProtectSystem=full` (which makes /usr, /boot, & /etc dirs read-only), and
612 `PrivateDevices=on` (which hides devices). You can override any of these
613 using the standard `systemctl edit rsync` and add one or more directives
614 under a `[Service]` heading (and restart the rsync service).
616 - Various checksum enhancements, including the optional use of openssl's MD4 &
617 MD5 checksum algorithms, some x86-64 optimizations for the rolling checksum,
618 some x86-64 optimizations for the (non-openssl) MD5 checksum, the addition
619 of xxHash checksum support, and a negotiation heuristic that ensures that it
620 is easier to add new checksum algorithms in the future. The environment
621 variable `RSYNC_CHECKSUM_LIST` can be used to customize the preference order
622 of the negotiation, or use `--checksum-choice` (`--cc`) to force a choice.
624 - Various compression enhancements, including the addition of zstd and lz4
625 compression algorithms and a negotiation heuristic that picks the best
626 compression option supported by both sides. The environment variable
627 `RSYNC_COMPRESS_LIST` can be used to customize the preference order of the
628 negotiation, or use `--compress-choice` (`--zc`) to force a choice.
630 - Added a `--debug=NSTR` option that outputs details of the new negotiation
631 strings (for checksums and compression). The first level just outputs the
632 result of each negotiation on the client, level 2 outputs the values of the
633 strings that were sent to and received from the server, and level 3 outputs
634 all those values on the server side too (when the server was given the debug
637 - The `--debug=OPTS` command-line option is no longer auto-forwarded to the
638 remote rsync which allows for the client and server to have different levels
639 of debug specified. This also allows for newer debug options to be
640 specified, such as using `--debug=NSTR` to see the negotiated hash result,
641 without having the command fail if the server version is too old to handle
642 that debug item. Use `-M--debug=OPTS` to send the options to the remote side.
644 - Added the `--atimes` option based on the long-standing patch (just with some
645 fixes that the patch has been needing).
647 - Added `--open-noatime` option to open files using `O_NOATIME`.
649 - Added the `--write-devices` option based on the long-standing patch.
651 - Added openssl & preliminary gnutls support to the rsync-ssl script, which is
652 now installed by default. This was unified with the old stunnel-rsync
653 helper script to simplify packaging. Note that the script accepts the use
654 of `--type=gnutls` for gnutls testing, but does not look for gnutls-cli on
655 the path yet. The use of `--type=gnutls` will not work right until
656 gnutls-cli no longer drops data.
658 - Rsync was enhanced to set the `RSYNC_PORT` environment variable when running
659 a daemon-over-rsh script. Its value is the user-specified port number (set
660 via `--port` or an rsync:// URL) or 0 if the user didn't override the port.
662 - Added the `proxy protocol` daemon parameter that allows your rsyncd to know
663 the real remote IP when it is setup behind a proxy.
665 - Added negated matching to the daemon's `refuse options` setting by using
666 match strings that start with a `!` (such as `!compress*`). This lets you
667 refuse all options except for a particular approved list, for example. It
668 also lets rsync refuse certain options by default (such as `write-devices`)
669 while allowing the config to override that, as desired.
671 - Added the `early exec` daemon parameter that runs a script before the
672 transfer parameters are known, allowing some early setup based on module
675 - Added status output in response to a signal (via both SIGINFO & SIGVTALRM).
677 - Added `--copy-as=USER` option to give some extra security to root-run rsync
678 commands into/from untrusted directories (such as backups and restores).
680 - When resuming the transfer of a file in the `--partial-dir`, rsync will now
681 update that partial file in-place instead of creating yet another tmp file
682 copy. This requires both sender & receiver to be at least v3.2.0.
684 - Added support for `RSYNC_SHELL` & `RSYNC_NO_XFER_EXEC` environment variables
685 that affect the early, pre-xfer, and post-xfer exec rsync daemon parameters.
687 - Optimize the `--fuzzy --fuzzy` heuristic to avoid the fuzzy directory scan
688 until all other basis-file options are exhausted (such as `--link-dest`).
690 - Have the daemon log include the normal-exit sent/received stats when the
691 transfer exited with an error when possible (i.e. if it is the sender).
693 - The daemon now locks its pid file (when configured to use one) so that it
694 will not fail to start when the file exists but no daemon is running.
696 - Various manpage improvements, including some html representations (that
697 aren't installed by default).
699 - Made `-V` the short option for `--version` and improved its information.
701 - Pass the `-4` or `-6` option to the ssh command, making it easier to type
702 than `--rsh='ssh -4'` (or the `-6` equivalent).
704 - Added example config for rsyncd SSL proxy configs to rsyncd.conf.
706 - More errors messages now mention if the error is coming from the sender or
709 ### PACKAGING RELATED:
711 - Add installed bash script: /usr/bin/rsync-ssl
713 - Add installed manpage: /usr/man/man1/rsync-ssl.1
715 - Tweak auxiliary doc file names, such as: README.md, INSTALL.md, & NEWS.md.
717 - The rsync-ssl script wants to run openssl or stunnel4, so consider adding a
718 dependency for one of those options (though it's probably fine to just let
719 it complain about being unable to find the program and let the user decide
720 if they want to install one or the other).
722 - If you packaged rsync + rsync-ssl + rsync-ssl-daemon as separate packages,
723 the rsync-ssl package is now gone (rsync-ssl should be considered to be
724 mainstream now that Samba requires SSL for its rsync daemon).
726 - Add _build_ dependency for liblz4-dev, libxxhash-dev, libzstd-dev, and
727 libssl-dev. These development libraries will give rsync extra compression
728 algorithms, extra checksum algorithms, and allow use of openssl's crypto
729 lib for (potentially) faster MD4/MD5 checksums.
731 - Add _build_ dependency for g++ or clang++ on x86_64 systems to enable the
732 SIMD checksum optimizations.
734 - Add _build_ dependency for _either_ python3-cmarkcfm or python3-commonmark
735 to allow for patching of manpages or building a git release. This is not
736 required for a release-tar build, since it comes with pre-built manpages.
737 Note that cmarkcfm is faster than commonmark, but they generate the same
738 data. The commonmark dependency is easiest to install since it's native
739 python, and can even be installed via `pip3 install --user commonmark` if
740 you want to just install it for the build user.
742 - Remove yodl _build_ dependency (if it was even listed before).
744 ### DEVELOPER RELATED:
746 - Silenced some annoying warnings about major() & minor() by improving an
747 autoconf include-file check.
749 - Converted the manpages from yodl to markdown. They are now processed via a
750 simple python3 script using the cmarkgfm **or** commonmark library. This
751 should make it easier to package rsync, since yodl is rather obscure.
753 - Improved some configure checks to work better with strict C99 compilers.
755 - Some perl building/packaging scripts were recoded into awk and python3.
757 - Some defines in byteorder.h were changed into static inline functions that
758 will help to ensure that the args don't get evaluated multiple times on
759 "careful alignment" hosts.
761 - Some code typos were fixed (as pointed out by a Fossies run).
763 ------------------------------------------------------------------------------
765 # NEWS for rsync 3.1.3 (28 Jan 2018)
767 ## Changes in this version:
771 - Fixed a buffer overrun in the protocol's handling of xattr names and ensure
772 that the received name is null terminated.
774 - Fix an issue with `--protect-args` where the user could specify the arg in the
775 protected-arg list and short-circuit some of the arg-sanitizing code.
779 - Don't output about a new backup dir without appropriate info verbosity.
781 - Fixed some issues with the sort functions in the rsyncstats script (in the
784 - Added a way to specify daemon config lists (e.g. users, groups, etc) that
785 contain spaces (see `auth users` in the latest rsyncd.conf manpage).
787 - If a backup fails (e.g. full disk) rsync exits with an error.
789 - Fixed a problem with a doubled `--fuzzy` option combined with `--link-dest`.
791 - Avoid invalid output in the summary if either the start or end time had an
794 - We don't allow a popt alias to affect the `--daemon` or `--server` options.
796 - Fix daemon exclude code to disallow attribute changes in addition to
797 disallowing transfers.
799 - Don't force nanoseconds to match if a non-transferred, non-checksummed file
800 only passed the quick-check w/o comparing nanoseconds.
804 - Added the ability for rsync to compare nanosecond times in its file-check
805 comparisons, and added support nanosecond times on Mac OS X.
807 - Added a short-option (`-@`) for `--modify-window`.
809 - Added the `--checksum-choice=NAME[,NAME]` option to choose the checksum
812 - Added hashing of xattr names (with using `-X`) to improve the handling of
813 files with large numbers of xattrs.
815 - Added a way to filter xattr names using include/exclude/filter rules (see
816 the `--xattrs` option in the manpage for details).
818 - Added `daemon chroot|uid|gid` to the daemon config (in addition to the old
819 chroot|uid|gid settings that affect the daemon's transfer process).
821 - Added `syslog tag` to the daemon configuration.
823 - Some manpage improvements.
825 ### DEVELOPER RELATED:
827 - Tweak the `make` output when yodl isn't around to create the manpages.
829 - Changed an obsolete autoconf compile macro.
831 - Support newer yodl versions when converting manpages.
833 ------------------------------------------------------------------------------
835 # NEWS for rsync 3.1.2 (21 Dec 2015)
837 ## Changes in this version:
841 - Make sure that all transferred files use only path names from inside the
842 transfer. This makes it impossible for a malicious sender to try to make the
843 receiver use an unsafe destination path for a transferred file, such as a
848 - Change the checksum seed order in the per-block checksums. This prevents
849 someone from trying to create checksum blocks that match in sum but not
852 - Fixed a with the per-dir filter files (using `-FF`) that could trigger an
855 - Only skip `set_modtime()` on a transferred file if the time is exactly
858 - Don't create an empty backup dir for a transferred file that doesn't exist
861 - Fixed a bug where `--link-dest` and `--xattrs` could cause rsync to exit if
862 a filename had a matching dir of the same name in the alt-dest area.
864 - Allow more than 32 group IDs per user in the daemon's gid=LIST config.
866 - Fix the logging of %b & %c via `--log-file` (daemon logging was already
867 correct, as was `--out-format='%b/%c'`).
869 - Fix erroneous acceptance of `--info=5` & `--debug=5` (an empty flag name is
874 - Added `(DRY RUN)` info to the `--debug=exit` output line.
876 - Use usleep() for our msleep() function if it is available.
878 - Added a few extra long-option names to rrsync script, which will make
881 - Made configure choose to use Linux xattrs on NetBSD (rather than not
884 - Added `-wo` (write-only) option to rrsync support script.
886 - Misc. manpage tweaks.
888 ### DEVELOPER RELATED:
890 - Fixed a bug with the Makefile's use of `INSTALL_STRIP`.
892 - Improve a test in the suite that could get an erroneous timestamp error.
894 - Tweaks for newer versions of git in the packaging tools.
896 - Improved the m4 generation rules and some autoconf idioms.
898 ------------------------------------------------------------------------------
900 # NEWS for rsync 3.1.1 (22 Jun 2014)
902 ## Changes in this version:
906 - If the receiver gets bogus filenames from the sender (an unexpected leading
907 slash or a `..` infix dir), exit with an error. This prevents a malicious
908 sender from trying to inject filenames that would affect an area outside the
909 destination directories.
911 - Fixed a failure to remove the partial-transfer temp file when interrupted
912 (and rsync is not saving the partial files).
914 - Changed the chown/group/xattr-set order to avoid losing some security-
915 related xattr info (that would get cleared by a chown).
917 - Fixed a bug in the xattr-finding code that could make a non-root-run
918 receiver not able to find some xattr numbers.
920 - Fixed a bug in the early daemon protocol where a timeout failed to be
921 honored (e.g. if the remote side fails to send us the initial protocol
924 - Fixed unintended inclusion of commas in file numbers in the daemon log.
926 - We once again send the 'f' sub-flag (of `-e`) to the server side so it knows
927 that we can handle incremental-recursion directory errors properly in older
930 - Fixed an issue with too-aggressive keep-alive messages causing a problem for
931 older rsync versions early in the transfer.
933 - Fixed an incorrect message about backup-directory-creation when using
934 `--dry-run` and the backup dir is not an absolute path.
936 - Fixed a bug where a failed deletion and/or a failed sender-side removal
937 would not affect the exit code.
939 - Fixed a bug that caused a failure when combining `--delete-missing-args`
940 with `--xattrs` and/or `--acls`.
942 - Fixed a strange `dir_depth` assertion error that was caused by empty-dir
943 removals and/or duplicate files in the transfer.
945 - Fixed a problem with `--info=progress2`'s output stats where rsync would
946 only update the stats at the end of each file's transfer. It now uses the
947 data that is flowing for the current file, making the stats more accurate
950 - Fixed an itemize bug that affected the combo of `--link-dest`, `-X`, and
953 - Fixed a problem with delete messages not appearing in the log file when the
954 user didn't use `--verbose`.
956 - Improve chunked xattr reading for OS X.
958 - Removed an attempted hard-link xattr optimization that was causing a
959 transfer failure. This removal is flagged in the compatibility code, so if a
960 better fix can be discovered, we have a way to flip it on again.
962 - Fixed a bug when the receiver is not configured to be able to hard link
963 symlimks/devices/special-file items but the sender sent some of these items
964 flagged as hard-linked.
966 - We now generate a better error if the buffer overflows in `do_mknod()`.
968 - Fixed a problem reading more than 16 ACLs on some OSes.
970 - Fixed the reading of the secrets file to avoid an infinite wait when the
973 - Fixed a parsing problem in the `--usermap`/`--groupmap` options when using
976 - Switched Cygwin back to using socketpair `pipes` to try to speed it up.
978 - Added knowledge of a few new options to rrsync.
982 - Tweaked the temp-file naming when `--temp-dir=DIR` is used: the temp-file
983 names will not get a '.' prepended.
985 - Added support for a new-compression idiom that does not compress all the
986 matching data in a transfer. This can help rsync to use less cpu when a
987 transfer has a lot of matching data, and also makes rsync compatible with a
988 non-bundled zlib. See the `--new-compress` and `--old-compress` options in
991 - Added the rsync-no-vanished shell script. (See the support dir.)
993 - Made configure more prominently mention when we failed to find yodl (in case
994 the user wants to be able to generate manpages from `*.yo` files).
996 - Have manpage mention how a daemon's max-verbosity setting affects info and
997 debug options. Also added more clarification on backslash removals for
998 excludes that contain wildcards.
1000 - Have configure check if for the attr lib (for getxattr) for those systems
1001 that need to link against it explicitly.
1003 - Change the early dir-creation logic to only use that idiom in an
1004 inc-recursive copy that is preserving directory times. e.g. using
1005 `--omit-dir-times` will avoid these early directories being created.
1007 - Fix a bug in `cmp_time()` that would return a wrong result if the 2 times
1008 differed by an amount greater than what a `time_t` can hold.
1010 ### DEVELOPER RELATED:
1012 - We now include an example systemd file (in packaging/systemd).
1014 - Tweaked configure to make sure that any intended use of the included popt
1015 and/or zlib code is put early in the CFLAGS.
1017 ------------------------------------------------------------------------------
1019 # NEWS for rsync 3.1.0 (28 Sep 2013)
1021 ## Changes in this version:
1023 ### PROTOCOL NUMBER:
1025 - The protocol number was changed to 31.
1029 - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
1030 `--human-readable` option for a way to turn it off. See also the daemon's
1031 `log format` parameter and related command-line options (including
1032 `--out-format`) for a modifier that can be used to request digit-grouping or
1033 human-readable output in log escapes. (Note that log output is unchanged by
1036 - The `--list-only` option is now affected by the `--human-readable` setting.
1037 It will display digit groupings by default, and unit suffixes if higher
1038 levels of readability are requested. Also, the column width for the size
1039 output has increased from 11 to 14 characters when human readability is
1040 enabled. Use `--no-h` to get the old-style output and column size.
1042 - The output of the `--progress` option has changed: the string `xfer` was
1043 shortened to `xfr`, and the string `to-check` was shortened to `to-chk`,
1044 both designed to make room for the (by default) wider display of file size
1045 numbers without making the total line-length longer. Also, when incremental
1046 recursion is enabled, the string `ir-chk` will be used instead of `to-chk`
1047 up until the incremental-recursion scan is done, letting you know that the
1048 value to check and the total value will still be increasing as new files are
1051 - Enhanced the `--stats` output: 1) to mention how many files were created
1052 (protocol >= 28), 2) to mention how many files were deleted (a new line for
1053 protocol 31, but only output when `--delete` is in effect), and 3) to follow
1054 the file-count, created-count, and deleted-count with a subcount list that
1055 shows the counts by type. The wording of the transferred count has also
1056 changed so that it is clearer that it is only a count of regular files.
1060 - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a full
1063 - Fixed some rare bugs in `--iconv` processing that might cause a multi-byte
1064 character to get translated incorrectly.
1066 - Fixed a bogus `vanished file` error if some files were specified with `./`
1067 prefixes and others were not.
1069 - Fixed a bug in `--sparse` where an extra gap could get inserted after a
1072 - Changed the way `--progress` overwrites its prior output in order to make it
1073 nearly impossible for the progress to get overwritten by an error.
1075 - Improved the propagation of abnormal-exit error messages. This should help
1076 the client side to receive errors from the server when it is exiting
1077 abnormally, and should also avoid dying with an `connection unexpectedly
1078 closed` exit when the closed connection is really expected.
1080 - The sender now checks each file it plans to remove to ensure that it hasn't
1081 changed from the first stat's info. This helps to avoid losing file data
1082 when the user is not using the option in a safe manner.
1084 - Fixed a data-duplication bug in the compress option that made compression
1085 less efficient. This improves protocol 31 onward, while behaving in a
1086 compatible (buggy) manner with older rsync protocols.
1088 - When creating a temp-file, rsync is now a bit smarter about it dot-char
1089 choices, which can fix a problem on OS X with names that start with `..`.
1091 - Rsync now sets a cleanup flag for `--inplace` and `--append` transfers that
1092 will flush the write buffer if the transfer aborts. This ensures that more
1093 received data gets written out to the disk on an aborted transfer (which is
1094 quite helpful on a slow, flaky connection).
1096 - The reads that `map_ptr()` now does are aligned on 1K boundaries. This helps
1097 some filesystems and/or files that don't like unaligned reads.
1099 - Fix an issue in the msleep() function if time jumps backwards.
1101 - Fix daemon-server module-name splitting bug where an arg would get split
1102 even if `--protect-args` was used.
1106 - Added the `--remote-option=OPT` (`-M OPT`) command-line option that is
1107 useful for things like sending a remote `--log-file=FILE` or `--fake-super`
1110 - Added the `--info=FLAGS` and `--debug=FLAGS` options to allow finer-grained
1111 control over what is output. Added an extra type of `--progress` output
1112 using `--info=progress2`.
1114 - The `--msgs2stderr` option can help with debugging rsync by allowing the
1115 debug messages to get output to stderr rather than travel via the socket
1118 - Added the `--delete-missing-args` and `--ignore-missing-args` options to
1119 either delete or ignore user-specified files on the receiver that are
1120 missing on the sender (normally the absence of user-specified files
1121 generates an error).
1123 - Added a `T` (terabyte) category to the `--human-readable` size suffixes.
1125 - Added the `--usermap`/`--groupmap`/`--chown` options for manipulating file
1126 ownership during the copy.
1128 - Added the `%C` escape to the log-output handling, which will output the MD5
1129 checksum of any transferred file, or all files if `--checksum` was specified
1130 (when protocol 30 or above is in effect).
1132 - Added the `reverse lookup` parameter to the rsync daemon config file to
1133 allow reverse-DNS lookups to be disabled.
1135 - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can be
1136 disabled via `forward lookup` parameter (defaults to enabled).
1138 - Added a way for more than one group to be specified in the daemon's config
1139 file, including a way to specify that you want all of the specified user's
1140 groups without having to name them. Also changed the daemon to complain
1141 about an inability to set explicitly-specified uid/gid values, even when not
1142 run by a super-user.
1144 - The daemon now tries to send the user the error messages from the pre-xfer
1145 exec script when it fails.
1147 - Improved the use of alt-dest options into an existing hierarchy of files: If
1148 a match is found in an alt-dir, it takes precedence over an existing file.
1149 (We'll need to wait for a future version before attribute-changes on
1150 otherwise unchanged files are safe when using an existing hierarchy.)
1152 - Added per-user authorization options and group-authorization support to the
1153 daemon's `auth users` parameter.
1155 - Added a way to reference environment variables in a daemon's config file
1156 (using %VAR% references).
1158 - When replacing a non-dir with a symlink/hard-link/device/special-file, the
1159 update should now be done in an atomic manner.
1161 - Avoid re-sending xattr info for hard-linked files w/the same xattrs
1164 - The backup code was improved to use better logic maintaining the backup
1165 directory hierarchy. Also, when a file is being backed up, rsync tries to
1166 hard-link it into place so that the upcoming replacement of the destination
1167 file will be atomic (for the normal, non-inplace logic).
1169 - Added the ability to synchronize nanosecond modified times.
1171 - Added a few more default suffixes for the `dont compress` settings.
1173 - Added the checking of the `RSYNC_PROTECT_ARGS` environment variable to allow
1174 the default for the `--protect-args` command-line option to be overridden.
1176 - Added the `--preallocate` command-line option.
1178 - Allow `--password-file=-` to read the password from stdin (filename `-`).
1180 - Rsync now comes packaged with an rsync-ssl helper script that can be used to
1181 contact a remote rsync daemon using a piped-stunnel command. It also
1182 includes an stunnel config file to run the server side to support ssl daemon
1183 connections. See the packaging/lsb/rsync.spec file for one way to package
1184 the resulting files. (Suggestions for how to make this even easier to
1185 install & use are welcomed.)
1187 - Improved the speed of some `--inplace` updates when there are lots of
1188 identical checksum blocks that end up being unusable.
1190 - Added the `--outbuf=N|L|B` option for choosing the output buffering.
1192 - Repeating the `--fuzzy` option now causes the code to look for fuzzy matches
1193 inside alt-dest directories too.
1195 - The `--chmod` option now supports numeric modes, e.g. `--chmod=644,D755`
1197 - Added some Solaris xattr code.
1199 - Made an rsync daemon (the listening process) exit with a 0 status when it
1200 was signaled to die. This helps launchd.
1202 - Improved the `RSYNC_*` environment variables for the pre-xfer exec script:
1203 when a daemon is sent multiple request args, they are now joined into a
1204 single return value (separated by spaces) so that the `RSYNC_REQUEST`
1205 environment variable is accurate for any `pre-xfer exec`. The values in
1206 `RSYNC_ARG#` vars are no longer truncated at the `.` arg (prior to the
1207 request dirs/files), so that all the requested values are also listed
1208 (separately) in `RSYNC_ARG#` variables.
1212 - Added an `instant-rsyncd` script to the support directory, which makes it
1213 easy to configure a simple rsync daemon in the current directory.
1215 - Added the `mapfrom` and `mapto` scripts to the support directory, which
1216 makes it easier to do user/group mapping in a local transfer based on
1217 passwd/group files from another machine.
1219 - There's a new, improved version of the lsh script in the support dir: it's
1220 written in perl and supports `-u` without resorting to using sudo (when run
1221 as root). The old shell version is now named lsh.sh.
1223 - There is a helper script named rsync-slash-strip in the support directory
1224 for anyone that wants to change the way rsync handles args with trailing
1225 slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
1230 - The I/O code was rewritten to be simpler and do bigger buffered reads over
1231 the socket. The I/O between the receiver and the generator was changed to be
1232 standard multiplexed-I/O (like that over the socket).
1234 - The sender tries to use any dead time while the generator is looking for
1235 files to transfer in order to do sender-side directory scanning in a more
1238 - A daemon can now inform a client about a daemon-configured timeout value so
1239 that the client can assist in the keep-alive activity (protocol 31).
1241 - The filter code received some refactoring to make it more extendable, to
1242 read better, and do better sanity checking.
1244 - Really big numbers are now output using our own big-num routine rather than
1245 casting them to a double and using a %.0f conversion.
1247 - The `pool_alloc` library has received some minor improvements in alignment
1250 - Added `init_stat_x()` function to avoid duplication of acl/xattr init code.
1252 - The included zlib was upgraded from 1.2.3 to 1.2.8.
1254 - Rsync can now be compiled to use an unmodified zlib library instead of the
1255 tweaked one that is included with rsync. This will eventually become the
1256 default, at which point we'll start the countdown to removing the included
1257 zlib. Until then, feel free to configure using:
1259 ./configure `--with-included-zlib=no`
1261 ### DEVELOPER RELATED:
1263 - Added more conditional debug output.
1265 - Fixed some build issues for Android and Minix.
1267 ------------------------------------------------------------------------------
1269 # NEWS for rsync 3.0.9 (23 Sep 2011)
1271 ## Changes in this version:
1275 - Fix a crash bug in checksum scanning when `--inplace` is used.
1277 - Fix a hang if a hard-linked file cannot be opened by the sender (e.g. if it
1278 has no read permission).
1280 - Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
1282 - Fix a memory leak in the xattr code.
1284 - Fixed a bug with `--delete-excluded` when a filter merge file has a rule
1285 that specifies a receiver-only side restriction.
1287 - Fix a bug with the modifying of unwritable directories.
1289 - Fix `--fake-super`'s interaction with `--link-dest` same-file comparisons.
1291 - Fix the updating of the `curr_dir` buffer to avoid a duplicate slash.
1293 - Fix the directory permissions on an implied dot-dir when using `--relative`
1294 (e.g. /outside/path/././send/path).
1296 - Fixed some too-long sleeping instances when using `--bwlimit`.
1298 - Fixed when symlink ownership difference-checking gets compiled into
1299 `unchanged_attrs()`.
1301 - Improved the socket-error reporting when multiple protocols fail.
1303 - Fixed a case where a socket error could reference just-freed memory.
1305 - Failing to use a password file that was specified on the command-line is now
1308 - Fix the non-root updating of directories that don't have the read and/or
1311 - Make daemon-excluded file errors more error-like.
1313 - Fix a compilation issue on older C compilers (due to a misplaced var
1316 - Make configure avoid finding socketpair on Cygwin.
1318 - Avoid trying to reference `SO_BROADCAST` if the OS doesn't support it.
1320 - Fix some issues with the post-processing of the manpages.
1322 - Fixed the user home-dir handling in the lsh script. (See the support dir.)
1324 - Some minor manpage improvements.
1326 ------------------------------------------------------------------------------
1328 # NEWS for rsync 3.0.8 (26 Mar 2011)
1330 ## Changes in this version:
1334 - Fixed two buffer-overflow issues: one where a directory path that is exactly
1335 MAXPATHLEN was not handled correctly, and one handling a `--backup-dir` that
1336 is extra extra large.
1338 - Fixed a data-corruption issue when preserving hard-links without preserving
1339 file ownership, and doing deletions either before or during the transfer
1340 (CVE-2011-1097). This fixes some assert errors in the hard-linking code, and
1341 some potential failed checksums (via `-c`) that should have matched.
1343 - Fixed a potential crash when an rsync daemon has a filter/exclude list and
1344 the transfer is using ACLs or xattrs.
1346 - Fixed a hang if a really large file is being processed by an rsync that
1347 can't handle 64-bit numbers. Rsync will now complain about the file being
1348 too big and skip it.
1350 - For devices and special files, we now avoid gathering useless ACL and/or
1351 xattr information for files that aren't being copied. (The un-copied files
1352 are still put into the file list, but there's no need to gather data that is
1353 not going to be used.) This ensures that if the user uses `--no-D`, that
1354 rsync can't possibly complain about being unable to gather extended
1355 information from special files that are in the file list (but not in the
1358 - Properly handle requesting remote filenames that start with a dash. This
1359 avoids a potential error where a filename could be interpreted as a (usually
1362 - Fixed a bug in the comparing of upper-case letters in file suffixes for
1365 - If an rsync daemon has a module configured without a path setting, rsync
1366 will now disallow access to that module.
1368 - If the destination arg is an empty string, it will be treated as a reference
1369 to the current directory (as 2.x used to do).
1371 - If rsync was compiled with a newer time-setting function (such as lutimes),
1372 rsync will fall-back to an older function (such as utimes) on a system where
1373 the newer function is not around. This helps to make the rsync binary more
1374 portable in mixed-OS-release situations.
1376 - Fixed a batch-file writing bug that would not write out the full set of
1377 compatibility flags that the transfer was using. This fixes a potential
1378 protocol problem for a batch file that contains a sender-side I/O error: it
1379 would have been sent in a way that the batch-reader wasn't expecting.
1381 - Some improvements to the hard-linking code to ensure that device-number
1382 hashing is working right, and to supply more information if the hard-link
1385 - The `--inplace` code was improved to not search for an impossible checksum
1386 position. The quadruple-verbose chunk[N] message will now mention when an
1387 inplace chunk was handled by a seek rather than a read+write.
1389 - Improved ACL mask handling, e.g. for Solaris.
1391 - Fixed a bug that prevented `--numeric-ids` from disabling the translation of
1392 user/group IDs for ACLs.
1394 - Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
1395 option (e.g. `--link-dest`) could output an error trying to itemize the
1396 changes against the alt-dest directory's xattr/ACL info but was instead
1397 trying to access the not-yet-existing new destination directory.
1399 - Improved xattr system-error messages to mention the full path to the file.
1401 - The `--link-dest` checking for identical symlinks now avoids considering
1402 attribute differences that cannot be changed on the receiver.
1404 - Avoid trying to read/write xattrs on certain file types for certain OSes.
1405 Improved configure to set `NO_SYMLINK_XATTRS`, `NO_DEVICE_XATTRS`, and/or
1406 `NO_SPECIAL_XATTRS` defines in config.h.
1408 - Improved the unsafe-symlink errors messages.
1410 - Fixed a bug setting xattrs on new files that aren't user writable.
1412 - Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
1414 - Fixed a bug with `--fake-super` when copying files and dirs that aren't user
1417 - Fixed a bug where a sparse file could have its last sparse block turned into
1418 a real block when rsync sets the file size (requires ftruncate).
1420 - If a temp-file name is too long, rsync now avoids truncating the name in the
1421 middle of adjacent high-bit characters. This prevents a potential filename
1422 error if the filesystem doesn't allow a name to contain an invalid
1423 multi-byte sequence.
1425 - If a muli-protocol socket connection fails (i.e., when contacting a daemon),
1426 we now report all the failures, not just the last one. This avoids losing a
1427 relevant error (e.g. an IPv4 connection-refused error) that happened before
1428 the final error (e.g. an IPv6 protocol-not-supported error).
1430 - Generate a transfer error if we try to call chown with a `-1` for a uid or a
1431 gid (which is not settable).
1433 - Fixed the working of `--force` when used with `--one-file-system`.
1435 - Fix the popt arg parsing so that an option that doesn't take an arg will
1436 reject an attempt to supply one (can configure `--with-included-popt` if
1437 your system's popt library doesn't yet have this fix).
1439 - A couple minor option tweaks to the rrsync script, and also some regex
1440 changes that make vim highlighting happier. (See the support dir.)
1442 - Fixed some issues in the mnt-excl script. (See the support dir.)
1444 - Various manpage improvements.
1448 - Added `.hg/` to the default cvs excludes (see `-C` & `--cvs-exclude`).
1450 ### DEVELOPER RELATED:
1452 - Use lchmod() whenever it is available (not just on symlinks).
1454 - A couple fixes to the `socketpair_tcp()` routine.
1456 - Updated the helper scripts in the packaging subdirectory.
1458 - Renamed configure.in to configure.ac.
1460 - Fixed configure's checking for iconv routines for newer OS X versions.
1462 - Fixed the testsuite/xattrs.test script on OS X.
1464 ------------------------------------------------------------------------------
1466 # NEWS for rsync 3.0.7 (31 Dec 2009)
1468 ## Changes in this version:
1472 - Fixed a bogus free when using `--xattrs` with `--backup`.
1474 - Avoid an error when `--dry-run` was trying to stat a prior hard-link file
1475 that hasn't really been created.
1477 - Fixed a problem with `--compress` (`-z`) where the receiving side could
1478 return the error "`inflate (token) returned -5`".
1480 - Fixed a bug where `--delete-during` could delete in a directory before it
1481 noticed that the sending side sent an I/O error for that directory (both
1482 sides of the transfer must be at least 3.0.7).
1484 - Improved `--skip-compress`'s error handling of bad character-sets and got
1485 rid of a lingering debug fprintf().
1487 - Fixed the daemon's conveyance of `io_error` value from the sender.
1489 - An rsync daemon use seteuid() (when available) if it used setuid().
1491 - Get the permissions right on a `--fake-super` transferred directory that
1492 needs more owner permissions to emulate root behavior.
1494 - An absolute-path filter rule (i.e. with a '/' modifier) no longer loses its
1495 modifier when sending the filter rules to the remote rsync.
1497 - Improved the "`--delete does not work without -r or -d`" message.
1499 - Improved rsync's handling of `--timeout` to avoid a weird timeout case where
1500 the sender could timeout even though it has recently written data to the
1501 socket (but hasn't read data recently, due to the writing).
1503 - Some misc manpage improvements.
1505 - Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
1507 - Make sure that a timeout specified in the daemon's config is used as a
1508 maximum timeout value when the user also specifies a timeout.
1510 - Improved the error-exit reporting when rsync gets an error trying to cleanup
1511 after an error: the initial error is reported.
1513 - Improved configure's detection of IPv6 for Solaris and Cygwin.
1515 - The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
1517 - Made our (only used if missing) getaddrinfo() routine use `inet_pton()`
1518 (which we also provide) instead of `inet_aton()`.
1520 - The exit-related debug messages now mention the program's role so it is
1521 clear who output what message.
1523 ### DEVELOPER RELATED:
1525 - Got rid of type-punned compiler warnings output by newer gcc versions.
1527 - The Makefile now ensures that proto.h will be rebuilt if config.h changes.
1529 - The testsuite no longer uses `id -u`, so it works better on Solaris.
1531 ------------------------------------------------------------------------------
1533 # NEWS for rsync 3.0.6 (8 May 2009)
1535 ## Changes in this version:
1539 - Fixed a `--read-batch` hang when rsync is reading a batch file that was
1540 created from an incremental-recursion transfer.
1542 - Fixed the daemon's socket code to handle the simultaneous arrival of
1543 multiple connections.
1545 - Fix `--safe-links`/`--copy-unsafe-links` to properly handle symlinks that
1546 have consecutive slashes in the value.
1548 - Fixed the parsing of an `[IPv6_LITERAL_ADDR]` when a USER@ is prefixed.
1550 - The sender now skips a (bogus) symlink that has a 0-length value, which
1551 avoids a transfer error in the receiver.
1553 - Fixed a case where the sender could die with a tag-0 error if there was an
1554 I/O during the sending of the file list.
1556 - Fixed the rrsync script to avoid a server-side problem when `-e` is at the
1557 start of the short options.
1559 - Fixed a problem where a vanished directory could turn into an exit code 23
1560 instead of the proper exit code 24.
1562 - Fixed the `--iconv` conversion of symlinks when doing a local copy.
1564 - Fixed a problem where `--one-file-system` was not stopping deletions on the
1565 receiving side when a mount-point directory did not match a directory in the
1568 - Fixed the dropping of an ACL mask when no named ACL values were present.
1570 - Fixed an ACL/xattr corruption issue where the `--backup` option could cause
1571 rsync to associate the wrong ACL/xattr information with received files.
1573 - Fixed the use of `--xattrs` with `--only-write-batch`.
1575 - Fixed the use of `--dry-run` with `--read-batch`.
1577 - Fixed configure's erroneous use of target.
1579 - Fixed configure's `--disable-debug` option.
1581 - Fixed a run-time issue for systems that can't find `iconv_open()` by adding
1582 the `--disable-iconv-open` configure option.
1584 - Complain and die if the user tries to combine `--remove-source-files` (or
1585 the deprecated `--remove-sent-files`) with `--read-batch`.
1587 - Fixed an failure transferring special files from Solaris to Linux.
1589 ------------------------------------------------------------------------------
1591 # NEWS for rsync 3.0.5 (28 Dec 2008)
1593 ## Changes in this version:
1597 - Initialize xattr data in a couple spots in the hlink code, which avoids a
1598 crash when the xattr pointer's memory happens to start out non-zero. Also
1599 fixed the itemizing of an alt-dest file's xattrs when hard-linking.
1601 - Don't send a bogus `-` option to an older server if there were no short
1604 - Fixed skipping of unneeded updates in a batch file when incremental
1605 recursion is active. Added a test for this. Made batch-mode handle `redo`
1606 files properly (and without hanging).
1608 - Fix the %P logfile escape when the daemon logs from inside a chroot.
1610 - Fixed the use of `-s` (`--protect-args`) when used with a remote source or
1611 destination that had an empty path (e.g. `host:`). Also fixed a problem when
1612 `-s` was used when accessing a daemon via a remote-shell.
1614 - Fixed the use of a dot-dir path (e.g. foo/./bar) inside a `--files-from`
1615 file when the root of the transfer isn't the current directory.
1617 - Fixed a bug with `-K --delete` removing symlinks to directories when
1618 incremental recursion is active.
1620 - Fixed a hard to trigger hang when using `--remove-source-files`.
1622 - Got rid of an annoying delay when accessing a daemon via a remote-shell.
1624 - Properly ignore (superfluous) source args on a `--read-batch` command.
1626 - Improved the manpage's description of the `*` wildcard to remove the
1627 confusing `non-empty` qualifier.
1629 - Fixed reverse lookups in the compatibility-library version of getnameinfo().
1631 - Fixed a bug when using `--sparse` on a sparse file that has over 2GB of
1632 consecutive sparse data.
1634 - Avoid a hang when using at least 3 `--verbose` options on a transfer with a
1635 client sender (which includes local copying).
1637 - Fixed a problem with `--delete-delay` reporting an error when it was ready
1638 to remove a directory that was now gone.
1640 - Got rid of a bunch of `warn_unused_result` compiler warnings.
1642 - If an ftruncate() on a received file fails, it now causes a partial-
1645 - Allow a path with a leading `//` to be preserved (CYGWIN only).
1649 - Made the atomic-rsync script able to perform a fully atomic update of the
1650 copied hierarchy when the destination is setup using a particular symlink
1651 idiom. (See the support dir.)
1653 ------------------------------------------------------------------------------
1655 # NEWS for rsync 3.0.4 (6 Sep 2008)
1657 ## Changes in this version:
1661 - Fixed a bug in the hard-linking code where it would sometimes try to
1662 allocate 0 bytes of memory (which fails on some OSes, such as AIX).
1664 - Fixed the hard-linking of files from a device that has a device number of 0
1665 (which seems to be a common device number on NetBSD).
1667 - Fixed the handling of a `--partial-dir` that cannot be created. This
1668 particularly impacts the `--delay-updates` option (since the files cannot be
1669 delayed without a partial-dir), and was potentially destructive if the
1670 `--remove-source-files` was also specified.
1672 - Fixed a couple issues in the `--fake-super` handling of xattrs when the
1673 destination files have root-level attributes (e.g. selinux values) that a
1674 non-root copy can't affect.
1676 - Improved the keep-alive check in the generator to fire consistently in
1677 incremental-recursion mode when `--timeout` is enabled.
1679 - The `--iconv` option now converts the content of a symlink too, instead of
1680 leaving it in the wrong character-set (requires 3.0.4 on both sides of the
1683 - When using `--iconv`, if a filename fails to convert on the receiving side,
1684 this no longer makes deletions in the root-dir of the transfer fail silently
1685 (the user now gets a warning about deletions being disabled due to IO error
1686 as long as `--ignore-errors` was not specified).
1688 - When using `--iconv`, if a server-side receiver can't convert a filename,
1689 the error message sent back to the client no longer mangles the name with
1690 the wrong charset conversion.
1692 - Fixed a potential alignment issue in the IRIX ACL code when allocating the
1693 initial `struct acl` object. Also, cast mallocs to avoid warnings.
1695 - Changed some errors that were going to stdout to go to stderr.
1697 - Made `human_num()` and `human_dnum()` able to output a negative number
1698 (rather than outputting a cryptic string of punctuation).
1702 - Rsync will avoid sending an `-e` option to the server if an older protocol
1703 is requested (and thus the option would not be useful). This lets the user
1704 specify the `--protocol=29` option to access an overly-restrictive server
1705 that is rejecting the protocol-30 use of `-e` to the server.
1707 - Improved the message output for an `RERR_PARTIAL` exit.
1709 ### DEVELOPER RELATED:
1711 - The Makefile will not halt for just a timestamp change on the Makefile or
1712 the configure files, only for actual changes in content.
1714 - Changed some commands in the testsuite's xattrs.test that called `rsync`
1715 instead of `$RSYNC`.
1717 - Enhanced the release scripts to be able to handle a branch release and to do
1718 even more consistency checks on the files.
1720 ------------------------------------------------------------------------------
1722 # NEWS for rsync 3.0.3 (29 Jun 2008)
1724 ## Changes in this version:
1728 - Fixed a wildcard matching problem in the daemon when a module has `use
1731 - Fixed a crash bug in the hard-link code.
1733 - Fixed the sending of xattr directory information when the code finds a
1734 `--link-dest` or `--copy-dest` directory with unchanged xattrs -- the
1735 destination directory now gets these unchanged xattrs properly applied.
1737 - Fixed an xattr-sending glitch that could cause an `Internal abbrev` error.
1739 - Fixed the combination of `--xattrs` and `--backup`.
1741 - The generator no longer allows a '.' dir to be excluded by a daemon-exclude
1744 - Fixed deletion handling when copying a single, empty directory (with no
1745 files) to a differently named, non-existent directory.
1747 - Fixed the conversion of spaces into dashes in the %M log escape.
1749 - Fixed several places in the code that were not returning the right errno
1750 when a function failed.
1752 - Fixed the backing up of a device or special file into a backup dir.
1754 - Moved the setting of the socket options prior to the connect().
1756 - If rsync exits in the middle of a `--progress` output, it now outputs a
1757 newline to help prevent the progress line from being overwritten.
1759 - Fixed a problem with how a destination path with a trailing slash or a
1760 trailing dot-dir was compared against the daemon excludes.
1762 - Fixed the sending of large (size > 16GB) files when talking to an older
1763 rsync (protocols < 30): we now use a compatible block size limit.
1765 - If a file's length is so huge that we overflow a checksum buffer count (i.e.
1766 several hundred TB), warn the user and avoid sending an invalid checksum
1767 struct over the wire.
1769 - If a source arg is excluded, `--relative` no longer adds the excluded arg's
1770 implied dirs to the transfer. This fix also made the exclude check happen in
1771 the better place in the sending code.
1773 - Use the `overflow_exit()` function for overflows, not `out_of_memory()`.
1775 - Improved the code to better handle a system that has only 32-bit file
1780 - The rsyncd.conf manpage now consistently refers to the parameters in the
1781 daemon config file as `parameters`.
1783 - The description of the `--inplace` option was improved.
1787 - Added a new script in the support directory, deny-rsync, which allows an
1788 admin to (temporarily) replace the rsync command with a script that sends an
1789 error message to the remote client via the rsync protocol.
1791 ### DEVELOPER RELATED:
1793 - Fixed a testcase failure if the tests are run as root and made some
1794 compatibility improvements.
1796 - Improved the daemon tests, including checking module comments, the listing
1797 of files, and the ensuring that daemon excludes can't affect a dot-dir arg.
1799 - Improved some build rules for those that build in a separate directory from
1800 the source, including better install rules for the manpages, and the fixing
1801 of a proto.h-tstamp rule that could make the binaries get rebuild without
1804 - Improved the testsuite to work around a problem with some utilities (e.g.
1805 `cp -p` & `touch -r`) rounding sub-second timestamps.
1807 - Ensure that the early patches don't cause any generated-file hunks to
1808 bleed-over into patches that follow.

1833 # NEWS for rsync 3.0.1 (3 Apr 2008)
1835 ## Changes in this version:
1837 ### NOTABLE CHANGES IN BEHAVIOR:
1839 - Added the 'c'-flag to the itemizing of non-regular files so that the
1840 itemized output doesn't get hidden if there were no attribute changes, and
1841 also so that the itemizing of a `--copy-links` run will distinguish between
1842 copying an identical non-regular file and the creation of a revised version
1843 with a new value (e.g. a changed symlink referent, a new device number,
1848 - Fixed a crash bug when a single-use rsync daemon (via remote shell) was run
1849 without specifying a `--config=FILE` option.
1851 - Fixed a crash when backing up a directory that has a default ACL.
1853 - Fixed a bug in the handling of xattr values that could cause rsync to not
1854 think that a file's extended attributes are up-to-date.
1856 - Fixed the working of `--fake-super` with `--link-dest` and `--xattrs`.
1858 - Fixed a hang when combining `--dry-run` with `--remove-source-files`.
1860 - Fixed a bug with `--iconv`'s handling of files that cannot be converted: a
1861 failed name can no longer cause a transfer failure.
1863 - Fixed the building of the rounding.h file on systems that need custom
1864 CPPFLAGS to be used. Also improved the error reporting if the building of
1867 - Fixed the use of the `--protect-args` (`-s`) option when talking to a
1870 - Fixed the `--ignore-existing` option's protection of files on the receiver
1871 that are non-regular files on the sender (e.g. if a symlink or a dir on the
1872 sender is trying to replace a file on the receiver). The reverse protection
1873 (protecting a dir/symlink/device from being replaced by a file) was already
1876 - Fixed an assert failure if `--hard-links` is combined with an option that
1877 can skip a file in a set of hard-linked files (i.e. `--ignore-existing`,
1878 `--append`, etc.), without skipping all the files in the set.
1880 - Avoid setting the modify time on a directory that already has the right
1881 modify time set. This avoids tweaking the dir's ctime.
1883 - Improved the daemon-exclude handling to do a better job of applying the
1884 exclude rules to path entries. It also sends the user an error just as if
1885 the files were actually missing (instead of silently ignoring the user's
1886 args), and avoids sending the user the filter-action messages for these
1887 non-user-initiated rules.
1889 - Fixed some glitches with the dry-run code's missing-directory handling,
1890 including a problem when combined with `--fuzzy`.
1892 - Fixed some glitches with the skipped-directory handling.
1894 - Fixed the 'T'-flag itemizing of symlinks when `--time` isn't preserved.
1896 - Fixed a glitch in the itemizing of permissions with the `-E` option.
1898 - The `--append` option's restricting of transfers to those that add data no
1899 longer prevents the updating of non-content changes to otherwise up-to-date
1900 files (i.e. those with the same content but differing permissions,
1901 ownership, xattrs, etc.).
1903 - Don't allow `--fake-super` to be specified with `-XX` (double `--xattrs`)
1904 because the options conflict. If a daemon has `fake super` enabled, it
1905 automatically downgrades a `-XX` request to `-X`.
1907 - Fixed a couple bugs in the parsing of daemon-config excludes that could make
1908 a floating exclude rule get treated as matching an absolute path.
1910 - A daemon doesn't try to auto-refuse the `iconv` option if iconv-support
1911 wasn't compiled in to the daemon (avoiding a warning in the logs).
1913 - Fixed the inclusion of per-dir merge files from implied dirs.
1915 - Fixed the rrsync script to work with the latest options that rsync sends,
1916 including its flag-specifying use of `-e` to the server. (See the support
1921 - Added the `--old-dirs` (`--old-d`) option to make it easier for a user to
1922 ask for file-listings with older rsync versions (this is easier than having
1923 to type `-r --exclude='/*/*'` manually).
1925 - When getting an error while asking an older rsync daemon for a file listing,
1926 rsync will try to notice if the error is a rejection of the `--dirs` (`-d`)
1927 option and let the user know how to work around the issue.
1929 - Added a few more `--no-OPTION` overrides.
1931 - Improved the documentation of the `--append` option.
1933 - Improved the documentation of the filter/exclude/include daemon parameters.
1937 - Fixed a couple minor bugs in the included popt library (ones which I sent to
1938 the official popt project for inclusion in the 1.14 release).
1940 - Fixed a stat() call that should have been `do_stat()` so that the proper
1941 normal/64-bit stat() function gets called. (Was in an area that should not
1942 have caused problems, though.)
1944 - Changed the file-glob code to do a directory scan without using the `glob`
1945 and `glob.h`. This lets us do the globbing with less memory churn, and also
1946 avoid adding daemon-excluded items to the returned args.
1948 ### DEVELOPER RELATED:
1950 - The configure script tries to get the user's compiler to not warn about
1951 unused function parameters if the build is not including one or more of the
1952 ACL/xattrs/iconv features.
1954 - The configure script now has better checks for figuring out if the included
1955 popt code should be used or not.
1957 - Fixed two testsuite glitches: avoid a failure if someone's `cd` command
1958 outputs the current directory when cd-ing to a relative path, and made the
1959 itemized test query how rsync was built to determine if it should expect
1960 hard-linked symlinks or not.
1962 - Updated the testsuite to verify that various bug fixes remain fixed.
1964 - The RPM spec file was updated to have: (1) comments for how to use the
1965 rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
1967 - Updated the build scripts to work with a revised FTP directory structure.

1971 # NEWS for rsync 3.0.0 (1 Mar 2008)
1973 ## Changes in this version:
1975 ### PROTOCOL NUMBER:
1977 - The protocol number was changed to 30.
1979 ### NOTABLE CHANGES IN BEHAVIOR:
1981 - The handling of implied directories when using `--relative` has changed to
1982 send them as directories (e.g. no implied dir is ever sent as a symlink).
1983 This avoids unexpected behavior and should not adversely affect most people.
1984 If you're one of those rare individuals who relied upon having an implied
1985 dir be duplicated as a symlink, you should specify the transfer of the
1986 symlink and the transfer of the referent directory as separate args. (See
1987 also `--keep-dirlinks` and `--no-implied-dirs`.) Also, exclude rules no
1988 longer have a partial effect on implied dirs.
1990 - Requesting a remote file-listing without specifying `-r` (`--recursive`) now
1991 sends the `-d` (`--dirs`) option to the remote rsync rather than sending
1992 `-r` along with an extra exclude of `/*/*`. If the remote rsync does not
1993 understand the `-d` option (i.e. it is 2.6.3 or older), you will need to
1994 either turn off `-d` (`--no-d`), or specify `-r --exclude='/*/*'` manually.
1996 - In `--dry-run` mode, the last line of the verbose summary text is output
1997 with a "(DRY RUN)" suffix to help remind you that no updates were made.
1998 Similarly, `--only-write-batch` outputs `(BATCH ONLY)`.
2000 - A writable rsync daemon with `use chroot` disabled now defaults to a
2001 symlink-munging behavior designed to make symlinks safer while also allowing
2002 absolute symlinks to be stored and retrieved. This also has the effect of
2003 making symlinks unusable while they're in the daemon's hierarchy. See the
2004 daemon's `munge symlinks` parameter for details.
2006 - Starting up an extra copy of an rsync daemon will not clobber the pidfile
2007 for the running daemon -- if the pidfile exists, the new daemon will exit
2008 with an error. This means that your wrapper script that starts the rsync
2009 daemon should be made to handle lock-breaking (if you want any automatic
2010 breaking of locks to be done).
2014 - A daemon with `use chroot = no` and excluded items listed in the daemon
2015 config file now properly checks an absolute-path arg specified for these
2016 options: `--compare-dest`, `--link-dest`, `--copy-dest`, `--partial-dir`,
2017 `--backup-dir`, `--temp-dir`, and `--files-from`.
2019 - A daemon can now be told to disable all user- and group-name translation on
2020 a per-module basis. This avoids a potential problem with a writable daemon
2021 module that has `use chroot` enabled -- if precautions weren't taken, a user
2022 could try to add a missing library and get rsync to use it. This makes rsync
2023 safer by default, and more configurable when id-translation is not desired.
2024 See the daemon's `numeric ids` parameter for full details.
2026 - A chroot daemon can now indicate which part of its path should affect the
2027 chroot call, and which part should become an inside-chroot path for the
2028 module. This allows you to have outside-the-transfer paths (such as for
2029 libraries) even when you enable chroot protection. The idiom used in the
2030 rsyncd.conf file is: `path = /chroot/dirs/./dirs/inside`
2032 - If a file's data arrived successfully on the receiving side but the rename
2033 of the temporary file to the destination file failed AND the
2034 `--remove-source-files` (or the deprecated `--remove-sent-files`) option was
2035 specified, rsync no longer erroneously removes the associated source file.
2037 - Fixed the output of `-ii` when combined with one of the `--*-dest` options:
2038 it now itemizes all the items, not just the changed ones.
2040 - Made the output of all file types consistent when using a `--*-dest` option.
2041 Prior versions would output too many creation events for matching items.
2043 - The code that waits for a child pid now handles being interrupted by a
2044 signal. This fixes a problem with the pre-xfer exec function not being able
2045 to get the exit status from the script.
2047 - A negated filter rule (i.e. with a '!' modifier) no longer loses the
2048 negation when sending the filter rules to the remote rsync.
2050 - Fixed a problem with the `--out-format` (aka `--log-format`) option %f: it
2051 no longer outputs superfluous directory info for a non-daemon rsync.
2053 - Fixed a problem with `-vv` (double `--verbose`) and `--stats` when `pushing`
2054 files (which includes local copies). Version 2.6.9 would complete the copy,
2055 but exit with an error when the receiver output its memory stats.
2057 - If `--password-file` is used on a non-daemon transfer, rsync now complains
2058 and exits. This should help users figure out that they can't use this option
2059 to control a remote shell's password prompt.
2061 - Make sure that directory permissions of a newly-created destination
2062 directory are handled right when `--perms` is left off.
2064 - The itemized output of a newly-created destination directory is now output
2065 as a creation event, not a change event.
2067 - Improved `--hard-link` so that more corner cases are handled correctly when
2068 combined with options such as `--link-dest` and/or `--ignore-existing`.
2070 - The `--append` option no longer updates a file that has the same size.
2072 - Fixed a bug when combining `--backup` and `--backup-dir` with `--inplace`:
2073 any missing backup directories are now created.
2075 - Fixed a bug when using `--backup` and `--inplace` with `--whole-file` or
2076 `--read-batch`: backup files are actually created now.
2078 - The daemon pidfile is checked and created sooner in the startup sequence.
2080 - If a daemon module's `path` value is not an absolute pathname, the code now
2081 makes it absolute internally (making it work properly).
2083 - Ensure that a temporary file always has owner-write permission while we are
2084 writing to it. This avoids problems with some network filesystems when
2085 transferring read-only files.
2087 - Any errors output about password-file reading no longer cause an error at
2088 the end of the run about a partial transfer.
2090 - The `--read-batch` option for protocol 30 now ensures that several more
2091 options are set correctly for the current batch file: `--iconv`, `--acls`,
2092 `--xattrs`, `--inplace`, `--append`, and `--append-verify`.
2094 - Using `--only-write-batch` to a daemon receiver now works properly (older
2095 versions would update some files while writing the batch).
2097 - Avoid outputting a "file has vanished" message when the file is a broken
2098 symlink and `--copy-unsafe-links` or `--copy-dirlinks` is used (the code
2099 already handled this for `--copy-links`).
2101 - Fixed the combination of `--only-write-batch` and `--dry-run`.
2103 - Fixed rsync's ability to remove files that are not writable by the file's
2104 owner when rsync is running as the same user.
2106 - When transferring large files, the sender's hashtable of checksums is kept
2107 at a more reasonable state of fullness (no more than 80% full) so that the
2108 scanning of the hashtable will not bog down as the number of blocks
2113 - A new incremental-recursion algorithm is now used when rsync is talking to
2114 another 3.x version. This starts the transfer going more quickly (before all
2115 the files have been found), and requires much less memory. See the
2116 `--recursive` option in the manpage for some restrictions.
2118 - Lowered memory use in the non-incremental-recursion algorithm for typical
2119 option values (usually saving from 21-29 bytes per file).
2121 - The default `--delete` algorithm is now `--delete-during` when talking to a
2122 3.x rsync. This is a faster scan than using `--delete-before` (which is the
2123 default when talking to older rsync versions), and is compatible with the
2124 new incremental recursion mode.
2126 - Rsync now allows multiple remote-source args to be specified rather than
2127 having to rely on a special space-splitting side-effect of the remote-
2128 shell. Additional remote args must specify the same host or an empty one
2129 (e.g. empty: `:file1` or `::module/file2`). For example, this means that
2130 local use of brace expansion now works: `rsync -av host:dir/{f1,f2} .`
2132 - Added the `--protect-args` (`-s`) option, that tells rsync to send most of
2133 the command-line args at the start of the transfer rather than as args to
2134 the remote-shell command. This protects them from space-splitting, and only
2135 interprets basic wildcard special shell characters (`*?[`).
2137 - Added the `--delete-delay` option, which is a more efficient way to delete
2138 files at the end of the transfer without needing a separate delete pass.
2140 - Added the `--acls` (`-A`) option to preserve Access Control Lists. This is
2141 an improved version of the prior patch that was available, and it even
2142 supports OS X ACLs. If you need to have backward compatibility with old,
2143 ACL-patched versions of rsync, apply the acls.diff file from the patches
2146 - Added the `--xattrs` (`-X`) option to preserve extended attributes. This is
2147 an improved version of the prior patch that was available, and it even
2148 supports OS X xattrs (which includes their resource fork data). If you need
2149 to have backward compatibility with old, xattr-patched versions of rsync,
2150 apply the xattrs.diff file from the patches dir.
2152 - Added the `--fake-super` option that allows a non-super user to preserve all
2153 attributes of a file by using a special extended-attribute idiom. It even
2154 supports the storing of foreign ACL data on your backup server. There is
2155 also an analogous `fake super` parameter for an rsync daemon.
2157 - Added the `--iconv` option, which allows rsync to convert filenames from one
2158 character-set to another during the transfer. The default is to make this
2159 feature available as long as your system has `iconv_open()`. If compilation
2160 fails, specify `--disable-iconv` to configure, and then rebuild. If you want
2161 rsync to perform character-set conversions by default, you can specify
2162 `--enable-iconv=CONVERT_STRING` with the default value for the `--iconv`
2163 option that you wish to use. For example, `--enable-iconv=.` is a good
2164 choice. See the rsync manpage for an explanation of the `--iconv` option's
2167 - A new daemon config parameter, `charset`, lets you control the character-
2168 set that is used during an `--iconv` transfer to/from a daemon module. You
2169 can also set your daemon to refuse `no-iconv` if you want to force the
2170 client to use an `--iconv` transfer (requiring an rsync 3.x client).
2172 - Added the `--skip-compress=LIST` option to override the default list of file
2173 suffixes that will not be compressed when using `--compress` (`-z`).
2175 - The daemon's default for `dont compress` was extended to include: `*.7z`
2176 `*.mp[34]` `*.mov` `*.avi` `*.ogg` `*.jpg` `*.jpeg` and the name-matching routine was also
2177 optimized to run more quickly.
2179 - The `--max-delete` option now outputs a warning if it skipped any file
2180 deletions, including a count of how many deletions were skipped. (Older
2181 versions just silently stopped deleting things.)
2183 - You may specify `--max-delete=0` to a 3.0.0 client to request that it warn
2184 about extraneous files without deleting anything. If you're not sure what
2185 version the client is, you can use the less-obvious `--max-delete=-1`, as
2186 both old and new versions will treat that as the same request (though older
2187 versions don't warn).
2189 - The `--hard-link` option now uses less memory on both the sending and
2190 receiving side for all protocol versions. For protocol 30, the use of a
2191 hashtable on the sending side allows us to more efficiently convey to the
2192 receiver what files are linked together. This reduces the amount of data
2193 sent over the socket by a considerable margin (rather than adding more
2194 data), and limits the in-memory storage of the device+inode information to
2195 just the sending side for the new protocol 30, or to the receiving side when
2196 speaking an older protocol (note that older rsync versions kept the
2197 device+inode information on both sides).
2199 - The filter rules now support a perishable (`p`) modifier that marks rules
2200 that should not have an effect in a directory that is being deleted. e.g.
2201 `-f '-p .svn/'` would only affect `live` .svn directories.
2203 - Rsync checks all the alternate-destination args for validity (e.g.
2204 `--link-dest`). This lets the user know when they specified a directory that
2207 - If we get an ENOSYS error setting the time on a symlink, we don't complain
2208 about it anymore (for those systems that even support the setting of the
2209 modify-time on a symlink).
2211 - Protocol 30 now uses MD5 checksums instead of MD4.
2213 - Changed the `--append` option to not checksum the existing data in the
2214 destination file, which speeds up file appending.
2216 - Added the `--append-verify` option, which works like the older `--append`
2217 option (verifying the existing data in the destination file). For
2218 compatibility with older rsync versions, any use of `--append` that is
2219 talking protocol 29 or older will revert to the `--append-verify` method.
2221 - Added the `--contimeout=SECONDS` option that lets the user specify a
2222 connection timeout for rsync daemon access.
2224 - Documented and extended the support for the `RSYNC_CONNECT_PROG` variable
2225 that can be used to enhance the client side of a daemon connection.
2227 - Improved the dashes and double-quotes in the nroff manpage output.
2229 - Rsync now supports a lot more `--no-OPTION` override options.
2233 - The file-list sorting algorithm now uses a sort that keeps any same-named
2234 items in the same order as they were specified. This allows rsync to always
2235 ensure that the first of the duplicates is the one that will be included in
2236 the copy. The new sort is also faster than the glibc version of qsort() and
2239 - Rsync now supports the transfer of 64-bit timestamps (`time_t` values).
2241 - Made the file-deletion code use a little less stack when recursing through a
2242 directory hierarchy of extraneous files.
2244 - Fixed a build problem with older (2.x) versions of gcc.
2246 - Added some isType() functions that make dealing with signed characters
2247 easier without forcing variables via casts.
2249 - Changed strcat/strcpy/sprintf function calls to use safer versions.
2251 - Upgraded the included popt version to 1.10.2 and improved its use of
2252 string-handling functions.
2254 - Added missing prototypes for compatibility functions from the lib dir.
2256 - Configure determines if iconv() has a const arg, allowing us to avoid a
2259 - Made the sending of some numbers more efficient for protocol 30.
2261 - Make sure that a daemon process doesn't mind if the client was weird and
2262 omitted the `--server` option.
2264 - There are more internal logging categories available in protocol 30 than the
2265 age-old FINFO and FERROR, including `FERROR_XFER` and FWARN. These new
2266 categories allow some errors and warnings to go to stderr without causing an
2267 erroneous end-of-run warning about some files not being able to be
2270 - Improved the use of `const` on pointers.
2272 - Improved J.W.'s `pool_alloc` routines to add a way of incrementally freeing
2273 older sections of a pool's memory.
2275 - The getaddrinfo.c compatibility code in the `lib` dir was replaced with some
2276 new code (derived from samba, derived from PostgreSQL) that has a better
2277 license than the old code.
2279 ### DEVELOPER RELATED:
2281 - Rsync is now licensed under the GPLv3 or later.
2283 - Rsync is now being maintained in a `git` repository instead of CVS (though
2284 the old CVS repository still exists for historical access). Several
2285 maintenance scripts were updated to work with git.
2287 - Generated files are no longer committed into the source repository. The
2288 autoconf and autoheader commands are now automatically run during the normal
2289 use of `configure` and `make`. The latest dev versions of all generated
2290 files can also be copied from the samba.org web site (see the prepare-source
2291 script's fetch option).
2293 - The `patches` directory of diff files is now built from branches in the
2294 rsync git repository (branch patch/FOO creates file patches/FOO.diff). This
2295 directory is now distributed in a separate separate tar file named
2296 rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
2298 - The proto.h file is now built using a simple perl script rather than a
2299 complex awk script, which proved to be more widely compatible.
2301 - When running the tests, we now put our per-test temp dirs into a sub-
2302 directory named testtmp (which is created, if missing). This allows someone
2303 to symlink the testtmp directory to another filesystem (which is useful if
2304 the build dir's filesystem does not support ACLs and xattrs, but another
2307 - Rsync now has a way of handling protocol-version changes during the
2308 development of a new protocol version. This causes any out-of-sync versions
2309 to speak an older protocol rather than fail in a cryptic manner. This
2310 addition makes it safer to deploy a pre-release version that may interact
2311 with the public. This new exchange of sub-version info does not interfere
2312 with the `{MIN,MAX}_PROTOCOL_VERSION` checking algorithm (which does not
2313 have enough range to allow the main protocol number to be incremented for
2314 every minor tweak in that happens during development).
2316 - The csprotocol.txt file was updated to mention the daemon protocol change in
2319 ------------------------------------------------------------------------------
2321 # NEWS for rsync 2.6.9 (6 Nov 2006)
2323 ## Changes in this version:
2327 - If rsync is interrupted via a handled signal (such as SIGINT), it will once
2328 again clean-up its temp file from the destination dir.
2330 - Fixed an overzealous sanitizing bug in the handling of the `--link-dest`,
2331 `--copy-dest`, and `--compare-dest` options to a daemon without chroot: if
2332 the copy's destination dir is deeper than the top of the module's path,
2333 these options now accept a safe number of parent-dir (../) references (since
2334 these options are relative to the destination dir). The old code incorrectly
2335 chopped off all `../` prefixes for these options, no matter how deep the
2336 destination directory was in the module's hierarchy.
2338 - Fixed a bug where a deferred info/error/log message could get sent directly
2339 to the sender instead of being handled by rwrite() in the generator. This
2340 fixes an `unexpected tag 3` fatal error, and should also fix a potential
2341 problem where a deferred info/error message from the receiver might bypass
2342 the log file and get sent only to the client process. (These problems could
2343 only affect an rsync daemon that was receiving files.)
2345 - Fixed a bug when `--inplace` was combined with a `--*-dest` option and we
2346 update a file's data using an alternate basis file. The code now notices
2347 that it needs to copy the matching data from the basis file instead of
2348 (wrongly) assuming that it was already present in the file.
2350 - Fixed a bug where using `--dry-run` with a `--*-dest` option with a path
2351 relative to a directory that does not yet exist: the affected option gets
2352 its proper path value so that the output of the dry-run is right.
2354 - Fixed a bug in the %f logfile escape when receiving files: the destination
2355 path is now included in the output (e.g. you can now tell when a user
2356 specifies a subdir inside a module).
2358 - If the receiving side fails to create a directory, it will now skip trying
2359 to update everything that is inside that directory.
2361 - If `--link-dest` is specified with `--checksum` but without `--times`, rsync
2362 will now allow a hard-link to be created to a matching link-dest file even
2363 when the file's modify-time doesn't match the server's file.
2365 - The daemon now calls more timezone-using functions prior to doing a chroot.
2366 This should help some C libraries to generate proper timestamps from inside
2367 a chrooted daemon (and to not try to access /etc/timezone over and over
2370 - Fixed a bug in the handling of an absolute `--partial-dir=ABS_PATH` option:
2371 it now deletes an alternate basis file from the partial-dir that was used to
2372 successfully update a destination file.
2374 - Fixed a bug in the handling of `--delete-excluded` when using a per-dir
2375 merge file: the merge file is now honored on the receiving side, and only
2376 its unqualified include/exclude commands are ignored (just as is done for
2377 global include/excludes).
2379 - Fixed a recent bug where `--delete` was not working when transferring from
2380 the root (/) of the filesystem with `--relative` enabled.
2382 - Fixed a recent bug where an `--exclude='*'` could affect the root (/) of the
2383 filesystem with `--relative` enabled.
2385 - When `--inplace` creates a file, it is now created with owner read/write
2386 permissions (0600) instead of no permissions at all. This avoids a problem
2387 continuing a transfer that was interrupted (since `--inplace` will not
2388 update a file that has no write permissions).
2390 - If either `--remove-source-files` or `--remove-sent-files` is enabled and we
2391 are unable to remove the source file, rsync now outputs an error.
2393 - Fixed a bug in the daemon's `incoming chmod` rule: newly-created directories
2394 no longer get the 'F' (file) rules applied to them.
2396 - Fixed an infinite loop bug when a filter rule was rejected due to being
2399 - When the server receives a `--partial-dir` option from the client, it no
2400 longer runs the client-side code that adds an assumed filter rule (since the
2401 client will be sending us the rules in the usual manner, and they may have
2402 chosen to override the auto-added rule).
2406 - Added the `--log-file=FILE` and `--log-file-format=FORMAT` options. These
2407 can be used to tell any rsync to output what it is doing to a log file.
2408 They work with a client rsync, a non-daemon server rsync (see the manpage
2409 for instructions), and also allows the overriding of rsyncd.conf settings
2410 when starting a daemon.
2412 - The `--log-format` option was renamed to be `--out-format` to avoid
2413 confusing it with affecting the log-file output. (The old option remains as
2414 an alias for the new to preserve backward compatibility.)
2416 - Made `log file` and `syslog facility` settable on a per-module basis in the
2417 daemon's config file.
2419 - Added the `--remove-source-files` option as a replacement for the (now
2420 deprecated) `--remove-sent-files` option. This new option removes all
2421 non-dirs from the source directories, even if the file was already
2422 up-to-date. This fixes a problem where interrupting an rsync that was using
2423 `--remove-sent-files` and restarting it could leave behind a file that the
2424 earlier rsync synchronized, but didn't get to remove. (The deprecated
2425 `--remove-sent-files` is still understood for now, and still behaves in the
2426 same way as before.)
2428 - Added the option `--no-motd` to suppress the message-of-the-day output from
2429 a daemon when doing a copy. (See the manpage for a caveat.)
2431 - Added a new environment variable to the pre-/post-xfer exec commands (in the
2432 daemon's config file): `RSYNC_PID`. This value will be the same in both the
2433 pre- and post-xfer commands, so it can be used as a unique ID if the
2434 pre-xfer command wants to cache some arg/request info for the post-xfer
2439 - Did a code audit using IBM's code-checker program and made several changes,
2440 including: replacing most of the strcpy() and sprintf() calls with
2441 strlcpy(), snprintf(), and memcpy(), adding a 0-value to an enum that had
2442 been intermingling a literal 0 with the defined enum values, silencing some
2443 uninitialized memory checks, marking some functions with a `noreturn`
2444 attribute, and changing an `if` that could never succeed on some platforms
2445 into a pre-processor directive that conditionally compiles the code.
2447 - Fixed a potential bug in `f_name_cmp()` when both the args are a top-level
2448 `.` dir (which doesn't happen in normal operations).
2450 - Changed `exit_cleanup()` so that it can never return instead of exit. The
2451 old code might return if it found the `exit_cleanup()` function was being
2452 called recursively. The new code is segmented so that any recursive calls
2453 move on to the next step of the exit-processing.
2455 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
2458 ### DEVELOPER RELATED:
2460 - The acls.diff and xattrs.diff patches have received a bunch of work to make
2461 them much closer to being acceptable in the main distribution. The xattrs
2462 patch also has some preliminary Mac OS X and FreeBSD compatibility code that
2463 various system types to exchange extended file-attributes.
2465 - A new diff in the patches dir, fake-root.diff, allows rsync to maintain a
2466 backup hierarchy with full owner, group, and device info without actually
2467 running as root. It does this using a special extended attribute, so it
2468 depends on xattrs.diff (which depends on acls.diff).
2470 - The rsync.yo and rsyncd.conf.yo files have been updated to work better with
2471 the latest yodl 2.x releases.
2473 - Updated config.guess and config.sub to their 2006-07-02 versions.
2475 - Updated various files to include the latest FSF address and to have
2476 consistent opening comments.
2478 ------------------------------------------------------------------------------
2480 # NEWS for rsync 2.6.8 (22 Apr 2006)
2482 ## Changes in this version:
2486 - Fixed a bug in the exclude code where an anchored exclude without any
2487 wildcards fails to match an absolute source arg, but only when `--relative`
2490 - Improved the I/O code for the generator to fix a potential hang when the
2491 receiver gets an EOF on the socket but the generator's select() call never
2492 indicates that the socket is writable for it to be notified about the EOF.
2493 (This can happen when using stunnel).
2495 - Fixed a problem with the file-reading code where a failed read (such as that
2496 caused by a bad sector) would not advance the file's read-position beyond
2497 the failed read's data.
2499 - Fixed a logging bug where the `log file` directive was not being honored in
2500 a single-use daemon (one spawned by a remote-shell connection or by init).
2502 - If rsync cannot honor the `--delete` option, we output an error and exit
2503 instead of silently ignoring the option.
2505 - Fixed a bug in the `--link-dest` code that prevented special files (such as
2506 fifos) from being linked.
2508 - The ability to hard-link symlinks and special files is now determined at
2509 configure time instead of at runtime. This fixes a bug with `--link-dest`
2510 creating a hard-link to a symlink's referent on a BSD system.
2514 - In daemon mode, if rsync fails to bind to the requested port, the error(s)
2515 returned by socket() and/or bind() are now logged.
2517 - When we output a fatal error, we now output the version of rsync in the
2520 - Improved the documentation for the `--owner` and `--group` options.
2522 - The rsyncstats script in `support` has an improved line-parsing regex that
2523 is easier to read and also makes it to parse syslog-generated lines.
2525 - A new script in `support`: file-attr-restore, can be used to restore the
2526 attributes of a file-set (the permissions, ownership, and group info) taken
2527 from the cached output of a `find ARG... -ls` command.
2529 ### DEVELOPER RELATED:
2531 - Removed the unused function `write_int_named()`, the unused variable
2532 `io_read_phase`, and the rarely used variable `io_write_phase`. This also
2533 elides the confusing 'phase "unknown"' part of one error message.
2535 - Removed two unused configure checks and two related (also unused)
2536 compatibility functions.
2538 - The xattrs.diff patch received a security fix that prevents a potential
2539 buffer overflow in the `receive_xattr()` code.
2541 - The acls.diff patch has been improved quite a bit, with more to come.
2543 - A new patch was added: log-file.diff. This contains an early version of a
2544 future option, `--log-file=FILE`, that will allow any rsync to log its
2545 actions to a file (something that only a daemon supports at present).
2547 ------------------------------------------------------------------------------
2549 # NEWS for rsync 2.6.7 (11 Mar 2006)
2551 ## Changes in this version:
2555 - The letter 'D' in the itemized output was being used for both devices
2556 (character or block) as well as other special files (such as fifos and named
2557 sockets). This has changed to separate non-device special files under the
2558 'S' designation (e.g. `cS+++++++ path/fifo`). See also the `--specials`
2561 - The way rsync escapes unreadable characters has changed. First, rsync now
2562 has support for recognizing valid multi-byte character sequences in your
2563 current locale, allowing it to escape fewer characters than before for a
2564 locale such as UTF-8. Second, it now uses an escape idiom of `\#123`, which
2565 is the literal string `\#` followed by exactly 3 octal digits. Rsync no
2566 longer doubles a backslash character in a filename (e.g. it used to output
2567 `foo\\bar` when copying `foo\bar`) -- now it only escapes a backslash that
2568 is followed by a hash-sign and 3 digits (0-9) (e.g. it will output
2569 `foo\#134#789` when copying `foo\#789`). See also the `--8-bit-output`
2570 (`-8`) option, mentioned below.
2572 Script writers: the local rsync is the one that outputs escaped names, so if
2573 you need to support unescaping of filenames for older rsyncs, I'd suggest
2574 that you parse the output of `rsync --version` and only use the old
2575 unescaping rules for 2.6.5 and 2.6.6.
2579 - Fixed a really old bug that caused `--checksum` (`-c`) to checksum all the
2580 files encountered during the delete scan (ouch).
2582 - Fixed a potential hang in a remote generator: when the receiver gets a
2583 read-error on the socket, it now signals the generator about this so that
2584 the generator does not try to send any of the terminating error messages to
2585 the client (avoiding a potential hang in some setups).
2587 - Made hard-links work with symlinks and devices again.
2589 - If the sender gets an early EOF reading a source file, we propagate this
2590 error to the receiver so that it can discard the file and try requesting it
2591 again (which is the existing behavior for other kinds of read errors).
2593 - If a device-file/special-file changes permissions, rsync now updates the
2594 permissions without recreating the file.
2596 - If the user specifies a remote-host for both the source and destination, we
2597 now output a syntax error rather than trying to open the destination
2598 hostspec as a filename.
2600 - When `--inplace` creates a new destination file, rsync now creates it with
2601 permissions 0600 instead of 0000 -- this makes restarting possible when the
2602 transfer gets interrupted in the middle of sending a new file.
2604 - Reject the combination of `--inplace` and `--sparse` since the sparse-output
2605 algorithm doesn't work when overwriting existing data.
2607 - Fixed the directory name in the error that is output when `pop_dir()` fails.
2609 - Really fixed the parsing of a `!` entry in .cvsignore files this time.
2611 - If the generator gets a stat() error on a file, output it (this used to
2612 require at least `-vv` for the error to be seen).
2614 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle the
2615 exit status properly and generate a better error.
2617 - Fixed some glitches in the double-verbose output when using `--copy-dest`,
2618 `--link-dest`, or `--compare-dest`. Also improved how the verbose output
2619 handles hard-links (within the transfer) that had an up-to-date alternate
2620 `dest` file, and copied files (via `--copy-dest`).
2622 - Fixed the matching of the dont-compress items (e.g. `*.gz`) against files
2623 that have a path component containing a slash.
2625 - If the code reading a filter/exclude file gets an EINTR error, rsync now
2626 clears the error flag on the file handle so it can keep on reading.
2628 - If `--relative` is active, the sending side cleans up trailing `/` or `/.`
2629 suffixes to avoid triggering a bug in older rsync versions. Also, we now
2630 reject a `..` dir if it would be sent as a relative dir.
2632 - If a non-directory is in the way of a directory and rsync is run with
2633 `--dry-run` and `--delete`, rsync no longer complains about not being able
2634 to opendir() the not-yet present directory.
2636 - When `--list-only` is used and a non-existent local destination dir was also
2637 specified as a destination, rsync no longer generates a warning about being
2638 unable to create the missing directory.
2640 - Fixed some problems with `--relative --no-implied-dirs` when the destination
2641 directory did not yet exist: we can now create a symlink or device when it
2642 is the first thing in the missing dir, and `--fuzzy` no longer complains
2643 about being unable to open the missing dir.
2645 - Fixed a bug where the `--copy-links` option would not affect implied
2646 directories without `--copy-unsafe-links` (see `--relative`).
2648 - Got rid of the need for `--force` to be used in some circumstances with
2649 `--delete-after` (making it consistent with
2650 `--delete-before`/`--delete-during`).
2652 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this when a
2653 file is too large (rsync handles the write error).
2655 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it was
2656 not properly padded with trailing '=' chars. This only affects a user that
2657 need to use a password-authenticated proxy for an outgoing daemon-rsync
2660 - If we're transferring an empty directory to a new name, rsync no longer
2661 forces `S_IWUSR` if it wasn't already set, nor does it accidentally leave it
2664 - Fixed a bug in the debug output (`-vvvvv`) that could mention the wrong
2665 checksum for the current file offset.
2667 - Rsync no longer allows a single directory to be copied over a non-directory
2672 - Added the `--append` option that makes rsync append data onto files that are
2673 longer on the source than the destination (this includes new files).
2675 - Added the `--min-size=SIZE` option to exclude small files from the transfer.
2677 - Added the `--compress-level` option to allow you to set how aggressive
2678 rsync's compression should be (this option implies `--compress`).
2680 - Enhanced the parsing of the SIZE value for `--min-size` and `--max-size` to
2681 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
2682 and off-by-one values too (e.g. `--max-size=8mb-1`).
2684 - Added the `--8-bit-output` (`-8`) option, which tells rsync to avoid
2685 escaping high-bit characters that it thinks are unreadable in the current
2688 - The new option `--human-readable` (`-h`) changes the output of `--progress`,
2689 `--stats`, and the end-of-run summary to be easier to read. If repeated, the
2690 units become powers of 1024 instead of powers of 1000. (The old meaning of
2691 `-h`, as a shorthand for `--help`, still works as long as you just use it on
2692 its own, as in `rsync -h`.)
2694 - If lutimes() and/or lchmod() are around, use them to allow the preservation
2695 of attributes on symlinks.
2697 - The `--link-dest` option now affects symlinks and devices (when possible).
2699 - Added two config items to the rsyncd.conf parsing: `pre-xfer exec` and
2700 `post-xfer exec`. These allow a command to be specified on a per-module
2701 basis that will be run before and/or after a daemon-mode transfer. (See the
2702 manpage for a list of the environment variables that are set with
2703 information about the transfer.)
2705 - When using the `--relative` option, you can now insert a dot dir in the
2706 source path to indicate where the replication of the source dirs should
2707 start. For example, if you specify a source path of
2708 rsync://host/module/foo/bar/./baz/dir with `-R`, rsync will now only
2709 replicate the `baz/dir` part of the source path (note: a trailing dot dir is
2710 unaffected unless it also has a trailing slash).
2712 - Added some new `--no-FOO` options that make it easier to override unwanted
2713 implied or default options. For example, `-a --no-o` (aka `--archive
2714 --no-owner`) can be used to turn off the preservation of file ownership that
2717 - Added the `--chmod=MODE` option that allows the destination permissions to
2718 be changed from the source permissions. E.g. `--chmod=g+w,o-rwx`
2720 - Added the `incoming chmod` and `outgoing chmod` daemon options that allow a
2721 module to specify what permissions changes should be applied to all files
2722 copied to and from the daemon.
2724 - Allow the `--temp-dir` option to be specified when starting a daemon, which
2725 sets the default temporary directory for incoming files.
2727 - If `--delete` is combined with `--dirs` without `--recursive`, rsync will
2728 now delete in any directory whose content is being synchronized.
2730 - If `--backup` is combined with `--delete` without `--backup-dir` (and
2731 without `--delete-excluded`), we add a `protect` filter-rule to ensure that
2732 files with the backup suffix are not deleted.
2734 - The file-count stats that are output by `--progress` were improved to better
2735 indicate what the numbers mean. For instance, the output: `(xfer#5,
2736 to-check=8383/9999)` indicates that this was the fifth file to be
2737 transferred, and we still need to check 8383 more files out of a total of
2740 - The include/exclude code now allows a `dir/***` directive (with 3 trailing
2741 stars) to match both the dir itself as well as all the content below the dir
2742 (`dir/**` would not match the dir).
2744 - Added the `--prune-empty-dirs` (`-m`) option that makes the receiving rsync
2745 discard empty chains of directories from the file-list. This makes it easier
2746 to selectively copy files from a source hierarchy and end up with just the
2747 directories needed to hold the resulting files.
2749 - If the `--itemize-changes` (`-i`) option is repeated, rsync now includes
2750 unchanged files in the itemized output (similar to `-vv`, but without all
2751 the other verbose messages that can get in the way). Of course, the client
2752 must be version 2.6.7 for this to work, but the remote rsync only needs to
2753 be 2.6.7 if you're pushing files.
2755 - Added the `--specials` option to tell rsync to copy non-device special files
2756 (which rsync now attempts even as a normal user). The `--devices` option now
2757 requests the copying of just devices (character and block). The `-D` option
2758 still requests both (e.g. `--devices` and `--specials`), `-a` still implies
2759 `-D`, and non-root users still get a silent downgrade that omits device
2762 - Added the `--super` option to make the receiver always attempt super-user
2763 activities. This is useful for systems that allow things such as devices to
2764 be created or ownership to be set without being UID 0, and is also useful
2765 for someone who wants to ensure that errors will be output if the receiving
2766 rsync isn't being run as root.
2768 - Added the `--sockopts` option for those few who want to customize the TCP
2769 options used to contact a daemon rsync.
2771 - Added a way for the `--temp-dir` option to be combined with a partial-dir
2772 setting that lets rsync avoid non-atomic updates (for those times when
2773 `--temp-dir` is not being used because space is tight).
2775 - A new support script, files-to-excludes, will transform a list of files into
2776 a set of include/exclude directives that will copy those files.
2778 - A new option, `--executability` (`-E`) can be used to preserve just the
2779 execute bit on files, for those times when using the `--perms` option is not
2782 - The daemon now logs each connection and also each module-list request that
2785 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B (permission
2786 bits, e.g. `rwxr-xrwt`).
2788 - The `--dry-run` option no longer forces the enabling of `--verbose`.
2790 - The `--remove-sent-files` option now does a better job of incrementally
2791 removing the sent files on the sending side (older versions tended to clump
2792 up all the removals at the end).
2794 - A daemon now supersedes its minimal SIGCHLD handler with the standard
2795 PID-remembering version after forking. This ensures that the generator can
2796 get the child-exit status from the receiver.
2798 - Use of the `--bwlimit` option no longer interferes with the remote rsync
2799 sending error messages about invalid/refused options.
2801 - Rsync no longer returns a usage error when used with one local source arg
2802 and no destination: this now implies the `--list-only` option, just like the
2803 comparable situation with a remote source arg.
2805 - Added the `--copy-dirlinks` option, a more limited version of
2808 - Various documentation improvements, including: a better synopsis, some
2809 improved examples, a better discussion of the presence and absence of
2810 `--perms` (including how it interacts with the new `--executability` and
2811 `--chmod` options), an extended discussion of `--temp-dir`, an improved
2812 discussion of `--partial-dir`, a better description of rsync's pattern
2813 matching characters, an improved `--no-implied-dirs` section, and the
2814 documenting of what the `--stats` option outputs.
2816 - Various new and updated diffs in the patches dir, including: acls.diff,
2817 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
2821 - We now use sigaction() and sigprocmask() if possible, and fall back on
2822 signal() if not. Using sigprocmask() ensures that rsync enables all the
2823 signals that it needs, just in case it was started in a masked state.
2825 - Some buffer sizes were expanded a bit, particularly on systems where
2826 MAXPATHLEN is overly small (e.g. Cygwin).
2828 - If `io_printf()` tries to format more data than fits in the buffer, exit
2829 with an error instead of transmitting a truncated buffer.
2831 - If a `va_copy` macro is defined, lib/snprintf.c will use it when defining
2832 the `VA_COPY` macro.
2834 - Reduced the amount of stack memory needed for each level of directory
2835 recursion by nearly MAXPATHLEN bytes.
2837 - The wildmatch function was extended to allow an array of strings to be
2838 supplied as the string to match. This allows the exclude code to do less
2841 - Got rid of the `safe_fname()` function (and all the myriad calls) and
2842 replaced it with a new function in the log.c code that filters all the
2843 output going to the terminal.
2845 - Unified the `f_name()` and the `f_name_to()` functions.
2847 - Improved the hash-table code the sender uses to handle checksums to make it
2848 use slightly less memory and run just a little faster.
2850 ### DEVELOPER RELATED:
2852 - The diffs in the patches dir now require `patch -p1 <DIFF` instead of the
2853 previous `-p0`. Also, the version included in the release tar now affect
2854 generated files (e.g. configure, rsync.1, proto.h, etc.), so it is no longer
2855 necessary to run autoconf and/or yodl unless you're applying a patch that
2856 was checked out from CVS.
2858 - Several diffs in the patches dir now use the proper `--enable-FOO` configure
2859 option instead of `--with-FOO` to turn on the inclusion of the newly patched
2862 - There is a new script, `prepare-source` than can be used to update the
2863 various generated files (proto.h, configure, etc.) even before configure has
2864 created the Makefile (this is mainly useful when patching the source with a
2865 patch that doesn't affect generated files).
2867 - The testsuite now sets HOME so that it won't be affected by a file such as
2870 ------------------------------------------------------------------------------
2872 # NEWS for rsync 2.6.6 (28 Jul 2005)
2874 ## Changes in this version:
2878 - The zlib code was upgraded to version 1.2.3 in order to make it more secure.
2879 While the widely-publicized security problem in zlib 1.2.2 did not affect
2880 rsync, another security problem surfaced that affects rsync's zlib 1.1.4.
2884 - The setting of `flist->high` in `clean_flist()` was wrong for an empty list.
2885 This could cause `flist_find()` to crash in certain rare circumstances (e.g.
2886 if just the right directory setup was around when `--fuzzy` was combined
2887 with `--link-dest`).
2889 - The outputting of hard-linked files when verbosity was > 1 was not right:
2890 (1) Without `-i` it would output the name of each hard-linked file as though
2891 it had been changed; it now outputs a `is hard linked` message for the file.
2892 (2) With `-i` it would output all dots for the unchanged attributes of a
2893 hard-link; it now changes those dots to spaces, as is done for other totally
2896 - When backing up a changed symlink or device, get rid of any old backup item
2897 so that we don't get an `already exists` error.
2899 - A couple places that were comparing a local and a remote modification-time
2900 were not honoring the `--modify-window` option.
2902 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get set
2903 too often (if some non-significant mode bits differed).
2905 - Fixed a really old, minor bug that could cause rsync to warn about being
2906 unable to mkdir() a path that ends in `/.` because it just created the
2907 directory (required `--relative`, `--no-implied-dirs`, a source path that
2908 ended in either a trailing slash or a trailing `/.`, and a non-existing
2909 destination dir to tickle the bug in a recent version).
2913 - Made the `max verbosity` setting in the rsyncd.conf file settable on a
2914 per-module basis (which now matches the documentation).
2916 - The rrsync script has been upgraded to verify the args of options that take
2917 args (instead of rejecting any such options). It was also changed to try to
2918 be more secure and to fix a problem in the parsing of a pull operation that
2919 has multiple source args. (See the support dir.)
2921 - Improved the documentation that explains the difference between a normal
2922 daemon transfer and a daemon-over remote-shell transfer.
2924 - Some of the diffs supplied in the patches dir were fixed and/or improved.
2928 - Made configure define `NOBODY_USER` (currently hard-wired to `nobody`) and
2929 `NOBODY_GROUP` (set to either `nobody` or `nogroup` depending on what we
2930 find in the /etc/group file).
2932 - Added a test to the test suite, itemized.test, that tests the output of `-i`
2933 (log-format w/%i) and some double-verbose messages.
2935 ------------------------------------------------------------------------------
2937 # NEWS for rsync 2.6.5 (1 Jun 2005)
2939 ## Changes in this version:
2943 - Non-printable chars in filenames are now output using backslash-escaped
2944 characters rather than '?'s. Any non-printable character is output using 3
2945 digits of octal (e.g. `\n` -> `\012`), and a backslash is now output as
2946 `\\`. Rsync also uses your locale setting, which can make it treat fewer
2947 high-bit characters as non-printable.
2949 - If rsync received an empty file-list when pulling files, it would output a
2950 `nothing to do` message and exit with a 0 (success) exit status, even if the
2951 remote rsync returned an error (it did not do this under the same conditions
2952 when pushing files). This was changed to make the pulling behavior the same
2953 as the pushing behavior: we now do the normal end-of-run outputting
2954 (depending on options) and exit with the appropriate exit status.
2958 - A crash bug was fixed when a daemon had its `path` set to `/`, did not have
2959 chroot enabled, and used some anchored excludes in the rsyncd.conf file.
2961 - Fixed a bug in the transfer of a single file when `-H` is specified (rsync
2962 would either infinite loop or perhaps crash).
2964 - Fixed a case where the generator might try (and fail) to tweak the
2965 write-permissions of a read-only directory in list-only mode (this only
2966 caused an annoying warning message).
2968 - If `--compare-dest` or `--link-dest` uses a locally-copied file as the basis
2969 for an updated version, log this better when `--verbose` or `-i` is in
2972 - Fixed the accidental disabling of `--backup` during the `--delete-after`
2975 - Restored the ability to use the `--address` option in client mode (in
2976 addition to its use in daemon mode).
2978 - Make sure that some temporary progress information from the delete
2979 processing does not get left on the screen when it is followed by a newline.
2981 - When `--existing` skips a directory with extra verbosity, refer to it as a
2982 `directory`, not a `file`.
2984 - When transferring a single file to a different-named file, any generator
2985 messages that are source-file related no longer refer to the file by the
2986 destination filename.
2988 - Fixed a bug where hard-linking a group of files might fail if the generator
2989 hasn't created a needed destination directory yet.
2991 - Fixed a bug where a hard-linked group of files that is newly-linked to a
2992 file in a `--link-dest` dir doesn't link the files from the rest of the
2995 - When deleting files with the `--one-file-system` (`-x`) option set, rsync no
2996 longer tries to remove files from inside a mount-point on the receiving
2997 side. Also, we don't complain about being unable to remove the mount-point
3000 - Fixed a compatibility problem when using `--cvs-ignore` (`-C`) and sending
3001 files to an older rsync without using `--delete`.
3003 - Make sure that a `- !` or `+ !` include/exclude pattern does not trigger the
3004 list-clearing action that is reserved for `!`.
3006 - Avoid a timeout in the generator when the sender/receiver aren't handling
3007 the generator's checksum output quickly enough.
3009 - Fixed the omission of some directories in the delete processing when
3010 `--relative` (`-R`) was combined with a source path that had a trailing
3013 - Fixed a case where rsync would erroneously delete some files and then
3014 re-transfer them when the options `--relative` (`-R`) and `--recursive`
3015 (`-r`) were both enabled (along with `--delete`) and a source path had a
3018 - Make sure that `--max-size` doesn't affect a device or a symlink.
3020 - Make sure that a system with a really small MAXPATHLEN does not cause the
3021 buffers in `readfd_unbuffered()` to be too small to receive normal messages.
3022 (This mainly affected Cygwin.)
3024 - If a source pathname ends with a filename of `..`, treat it as if `../` had
3025 been specified (so that we don't copy files to the parent dir of the
3028 - If `--delete` is combined with a file-listing rsync command (i.e. no
3029 transfer is happening), avoid outputting a warning that we couldn't delete
3032 - If `--stats` is specified with `--delete-after`, ensure that all the
3033 `deleting` messages are output before the statistics.
3035 - Improved one `if` in the deletion code that was only checking errno for
3036 ENOTEMPTY when it should have also been checking for EEXIST (for
3037 compatibility with OS variations).
3041 - Added the `--only-write-batch=FILE` option that may be used (instead of
3042 `--write-batch=FILE`) to create a batch file without doing any actual
3043 updating of the destination. This allows you to divert all the file-updating
3044 data away from a slow data link (as long as you are pushing the data to the
3045 remote server when creating the batch).
3047 - When the generator is taking a long time to fill up its output buffer (e.g.
3048 if the transferred files are few, small, or missing), it now periodically
3049 flushes the output buffer so that the sender/receiver can get started on the
3050 files sooner rather than later.
3052 - Improved the keep-alive code to handle a long silence between the sender and
3053 the receiver that can occur when the sender is receiving the checksum data
3056 - Improved the auth-errors that are logged by the daemon to include some
3057 information on why the authorization failed: wrong user, password mismatch,
3058 etc. (The client-visible message is unchanged!)
3060 - Improved the client's handling of an `@ERROR` from a daemon so that it does
3061 not complain about an unexpectedly closed socket (since we really did expect
3062 the socket to close).
3064 - If the daemon can't open the log-file specified in rsyncd.conf, fall back to
3065 using syslog and log an appropriate warning. This is better than what was
3066 typically a totally silent (and fatal) failure (since a daemon is not
3067 usually run with the `--no-detach` option that was necessary to see the
3070 - The manpages now consistently refer to an rsync daemon as a `daemon`
3071 instead of a `server` (to distinguish it from the server process in a
3072 non-daemon transfer).
3074 - Made a small change to the rrsync script (restricted rsync -- in the support
3075 dir) to make a read-only server reject all `--remove-*` options when sending
3076 files (to future-proof it against the possibility of other similar options
3077 being added at some point).
3081 - Rsync now calls `setlocale(LC_CTYPE, "")`. This enables isprint() to better
3082 discern which filename characters need to be escaped in messages (which
3083 should result in fewer escaped characters in some locales).
3085 - Improved the naming of the log-file open/reopen/close functions.
3087 - Removed some protocol-compatibility code that was only needed to help
3088 someone running a pre-release of 2.6.4.
3092 - Added configure option `--disable-locale` to disable any use of setlocale()
3095 - Fixed a bug in the `SUPPORT{,_HARD}_LINKS` #defines which prevented rsync
3096 from being built without symlink or hard-link support.
3098 - Only #define `HAVE_REMSH` if it is going to be set to 1.
3100 - Configure now disables the use of mkstemp() under HP-UX (since they refuse
3101 to fix its broken handling of large files).
3103 - Configure now explicitly checks for the lseek64() function so that the code
3104 can use `HAVE_LSEEK64` instead of inferring lseek64()'s presence based on
3105 the presence of the `off64_t` type.
3107 - Configure no longer mentions the change in the default remote-shell (from
3108 rsh to ssh) that occurred for the 2.6.0 release.
3110 - Some minor enhancements to the test scripts.
3112 - Added a few new `*.diff` files to the patches dir, including a patch that
3113 enables the optional copying of extended attributes.
3115 ------------------------------------------------------------------------------
3117 # NEWS for rsync 2.6.4 (30 March 2005)
3119 ## Changes in this version:
3121 ### PROTOCOL NUMBER:
3123 - The protocol number was changed to 29.
3127 - When rsync deletes a directory and outputs a verbose message about it, it
3128 now appends a trailing slash to the name instead of (only sometimes)
3129 outputting a preceding "directory " string.
3131 - The `--stats` output will contain file-list time-statistics if both sides
3132 are 2.6.4, or if the local side is 2.6.4 and the files are being pushed
3133 (since the stats come from the sending side). (Requires protocol 29 for a
3136 - The `%o` (operation) log-format escape now has a third value (besides `send`
3137 and `recv`): `del.` (with trailing dot to make it 4 chars). This changes
3138 the way deletions are logged in the daemon's log file.
3140 - When the `--log-format` option is combined with `--verbose`, rsync now
3141 avoids outputting the name of the file twice in most circumstances. As long
3142 as the `--log-format` item does not refer to any post-transfer items (such
3143 as %b or %c), the `--log-format` message is output prior to the transfer, so
3144 `--verbose` is now the equivalent of a `--log-format` of '%n%L' (which
3145 outputs the name and any link info). If the log output must occur after the
3146 transfer to be complete, the only time the name is also output prior to the
3147 transfer is when `--progress` was specified (so that the name will precede
3148 the progress stats, and the full `--log-format` output will come after).
3150 - Non-printable characters in filenames are replaced with a '?' to avoid
3151 corrupting the screen or generating empty lines in the output.
3155 - Restore the list-clearing behavior of `!` in a .cvsignore file (2.6.3 was
3156 only treating it as a special token in an rsync include/exclude file).
3158 - The combination of `--verbose` and `--dry-run` now mentions the full list of
3159 changes that would be output without `--dry-run`.
3161 - Avoid a mkdir warning when removing a directory in the destination that
3162 already exists in the `--backup-dir`.
3164 - An OS that has a binary mode for its files (such as Cygwin) needed
3165 `setmode(fd, O_BINARY)` called on the temp-file we opened with mkstemp().
3166 (Fix derived from Cygwin's 2.6.3 rsync package.)
3168 - Fixed a potential hang when verbosity is high, the client side is the
3169 sender, and the file-list is large.
3171 - Fixed a potential protocol-corrupting bug where the generator could merge a
3172 message from the receiver into the middle of a multiplexed packet of data if
3173 only part of that data had been written out to the socket when the message
3174 from the generator arrived.
3176 - We now check if the OS doesn't support using mknod() for creating FIFOs and
3177 sockets, and compile-in some compatibility code using mkfifo() and socket()
3180 - Fixed an off-by-one error in the handling of `--max-delete=N`. Also, if the
3181 `--max-delete` limit is exceeded during a run, we now output a warning about
3182 this at the end of the run and exit with a new error code (25).
3184 - One place in the code wasn't checking if fork() failed.
3186 - The `ignore nonreadable` daemon parameter used to erroneously affect
3187 readable symlinks that pointed to a non-existent file.
3189 - If the OS does not have lchown() and a chown() of a symlink will affect the
3190 referent of a symlink (as it should), we no longer try to set the user and
3193 - The generator now properly runs the hard-link loop and the dir-time
3194 rewriting loop after we're sure that the redo phase is complete.
3196 - When `--backup` was specified with `--partial-dir=DIR`, where DIR is a
3197 relative path, the backup code was erroneously trying to backup a file that
3198 was put into the partial-dir.
3200 - If a file gets resent in a single transfer and the `--backup` option is
3201 enabled along with `--inplace`, rsync no longer performs a duplicate backup
3202 (it used to overwrite the first backup with the failed file).
3204 - One call to `flush_write_file()` was not being checked for an error.
3206 - The `--no-relative` option was not being sent from the client to a server
3209 - If an rsync daemon specified `dont compress = ...` for a file and the client
3210 tried to specify `--compress`, the libz code was not handling a compression
3211 level of 0 properly. This could cause a transfer failure if the block-size
3212 for a file was large enough (e.g. rsync might have exited with an error for
3215 - Fixed a bug that would sometimes surface when using `--compress` and sending
3216 a file with a block-size larger than 64K (either manually specified, or
3217 computed due to the file being really large). Prior versions of rsync would
3218 sometimes fail to decompress the data properly, and thus the transferred
3219 file would fail its verification.
3221 - If a daemon can't open the specified log file (i.e. syslog is not being
3222 used), die without crashing. We also output an error about the failure on
3223 stderr (which will only be seen if `--no-detach` was specified) and exit
3224 with a new error code (6).
3226 - A local transfer no longer duplicates all its include/exclude options (since
3227 the forked process already has a copy of the exclude list, there's no need
3228 to send them a set of duplicates).
3230 - The output of the items that are being updated by the generator (dirs,
3231 symlinks, devices) is now intermingled in the proper order with the output
3232 from the items that the receiver is updating (regular files) when pulling.
3233 This misordering was particularly bad when `--progress` was specified.
3234 (Requires protocol 29.)
3236 - When `--timeout` is specified, lulls that occur in the transfer while the
3237 generator is doing work that does not generate socket traffic (looking for
3238 changed files, deleting files, doing directory-time touch-ups, etc.) will
3239 cause a new keep-alive packet to be sent that should keep the transfer going
3240 as long as the generator continues to make progress. (Requires protocol 29.)
3242 - The stat size of a device is not added to the total file size of the items
3243 in the transfer (the size might be undefined on some OSes).
3245 - Fixed a problem with refused-option messages sometimes not making it back to
3246 the client side when a remote `--files-from` was in effect and the daemon
3249 - The `--compare-dest` option was not updating a file that differed in (the
3250 preserved) attributes from the version in the compare-dest DIR.
3252 - When rsync is copying files into a write-protected directory, fixed the
3253 change-report output for the directory so that we don't report an identical
3254 directory as changed.
3258 - Rsync now supports popt's option aliases, which means that you can use
3259 /etc/popt and/or ~/.popt to create your own option aliases.
3261 - Added the `--delete-during` (`--del`) option which will delete files from
3262 the receiving side incrementally as each directory in the transfer is being
3263 processed. This makes it more efficient than the default,
3264 before-the-transfer behavior, which is now also available as
3265 `--delete-before` (and is still the default `--delete-WHEN` option that will
3266 be chosen if `--delete` or `--delete-excluded` is specified without a
3267 `--delete-WHEN` choice). All the `--del*` options infer `--delete`, so an
3268 rsync daemon that refuses `delete` will still refuse to allow any
3269 file-deleting options (including the new `--remove-sent-files` option).
3271 - All the `--delete-WHEN` options are now more memory efficient: Previously an
3272 duplicate set of file-list objects was created on the receiving side for the
3273 entire destination hierarchy. The new algorithm only creates one directory
3274 of objects at a time (for files inside the transfer).
3276 - Added the `--copy-dest` option, which works like `--link-dest` except that
3277 it locally copies identical files instead of hard-linking them.
3279 - Added support for specifying multiple `--compare-dest`, `--copy-dest`, or
3280 `--link-dest` options, but only of a single type. (Promoted from the patches
3281 dir and enhanced.) (Requires protocol 29.)
3283 - Added the `--max-size` option. (Promoted from the patches dir.)
3285 - The daemon-mode options are now separated from the normal rsync options so
3286 that they can't be mixed together. This makes it impossible to start a
3287 daemon that has improper default option values (which could cause problems
3288 when a client connects, such as hanging or crashing).
3290 - The `--bwlimit` option may now be used in combination with `--daemon` to
3291 specify both a default value for the daemon side and a value that cannot be
3292 exceeded by a user-specified `--bwlimit` option.
3294 - Added the `port` parameter to the rsyncd.conf file. (Promoted from the
3295 patches dir.) Also added `address`. The command-line options take precedence
3296 over a config-file option, as expected.
3298 - In `_exit_cleanup()`: when we are exiting with a partially-received file, we
3299 now flush any data in the write-cache before closing the partial file.
3301 - The `--inplace` support was enhanced to work with `--compare-dest`,
3302 `--link-dest`, and (the new) `--copy-dest` options. (Requires protocol 29.)
3304 - Added the `--dirs` (`-d`) option for an easier way to copy directories
3305 without recursion. Any directories that are encountered are created on the
3306 destination. Specifying a directory with a trailing slash copies its
3307 immediate contents to the destination.
3309 - The `--files-from` option now implies `--dirs` (`-d`).
3311 - Added the `--list-only` option, which is mainly a way for the client to put
3312 the server into listing mode without needing to resort to any internal
3313 option kluges (e.g. the age-old use of `-r --exclude='/*/*'` for a
3314 non-recursive listing). This option is used automatically (behind the
3315 scenes) when a modern rsync speaks to a modern daemon, but may also be
3316 specified manually if you want to force the use of the `--list-only` option
3317 over a remote-shell connection.
3319 - Added the `--omit-dir-times` (`-O`) option, which will avoid updating the
3320 modified time for directories when `--times` was specified. This option will
3321 avoid an extra pass through the file-list at the end of the transfer (to
3322 tweak all the directory times), which may provide an appreciable speedup for
3323 a really large transfer. (Promoted from the patches dir.)
3325 - Added the `--filter` (`-f`) option and its helper option, `-F`. Filter rules
3326 are an extension to the existing include/exclude handling that also supports
3327 nested filter files as well as per-directory filter files (like .cvsignore,
3328 but with full filter-rule parsing). This new option was chosen in order to
3329 ensure that all existing include/exclude processing remained 100% compatible
3330 with older versions. Protocol 29 is needed for full filter-rule support, but
3331 backward-compatible rules work with earlier protocol versions. (Promoted
3332 from the patches dir and enhanced.)
3334 - Added the `--delay-updates` option that puts all updated files into a
3335 temporary directory (by default `.~tmp~`, but settable via the
3336 `--partial-dir=DIR` option) until the end of the transfer. This makes the
3337 updates a little more atomic for a large transfer.
3339 - If rsync is put into the background, any output from `--progress` is
3342 - Documented the `max verbosity` setting for rsyncd.conf. (This setting was
3343 added a couple releases ago, but left undocumented.)
3345 - The sender and the generator now double-check the file-list index they are
3346 given, and refuse to try to do a file transfer on a non-file index (since
3347 that would indicate that something had gone very wrong).
3349 - Added the `--itemize-changes` (`-i`) option, which is a way to output a more
3350 detailed list of what files changed and in what way. The effect is the same
3351 as specifying a `--log-format` of `%i %n%L` (see both the rsync and
3352 rsyncd.conf manpages). Works with `--dry-run` too.
3354 - Added the `--fuzzy` (`-y`) option, which attempts to find a basis file for a
3355 file that is being created from scratch. The current algorithm only looks in
3356 the destination directory for the created file, but it does attempt to find
3357 a match based on size/mod-time (in case the file was renamed with no other
3358 changes) as well as based on a fuzzy name-matching algorithm. This option
3359 requires protocol 29 because it needs the new file-sorting order. (Promoted
3360 from patches dir and enhanced.) (Requires protocol 29.)
3362 - Added the `--remove-sent-files` option, which lets you move files between
3365 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal enclosed
3366 in '[' and ']' (e.g. `[::1]`). (We already allowed IPv6 literals in the
3367 rsync://HOST:PORT/PATH format.)
3369 - When rsync recurses to build the file list, it no longer keeps open one or
3370 more directory handles from the dir's parent dirs.
3372 - When building under windows, the default for `--daemon` is now to avoid
3373 detaching, requiring the new `--detach` option to force rsync to detach.
3375 - The `--dry-run` option can now be combined with either `--write-batch` or
3376 `--read-batch`, allowing you to run a do-nothing test command to see what
3377 would happen without `--dry-run`.
3379 - The daemon's `read only` config item now sets an internal `read_only`
3380 variable that makes extra sure that no write/delete calls on the read-only
3383 - The log-format % escapes can now have a numeric field width in between the %
3384 and the escape letter (e.g. `%-40n %08p`).
3386 - Improved the option descriptions in the `--help` text.
3390 - Added atomic-rsync to the support dir: a perl script that will transfer some
3391 files using rsync, and then move the updated files into place all at once at
3392 the end of the transfer. Only works when pulling, and uses `--link-dest` and
3393 a parallel hierarchy of files to effect its update.
3395 - Added mnt-excl to the support dir: a perl script that takes the /proc/mounts
3396 file and translates it into a set of excludes that will exclude all mount
3397 points (even mapped mounts to the same disk). The excludes are made relative
3398 to the specified source dir and properly anchored.
3400 - Added savetransfer.c to the support dir: a C program that can make a copy of
3401 all the data that flows over the wire. This lets you test for data
3402 corruption (by saving the data on both the sending side and the receiving
3403 side) and provides one way to debug a protocol error.
3405 - Added rrsync to the support dir: this is an updated version of Joe Smith's
3406 restricted rsync perl script. This helps to ensure that only certain rsync
3407 commands can be run by an ssh invocation.
3411 - Added better checking of the checksum-header values that come over the
3414 - Merged a variety of file-deleting functions into a single function so that
3415 it is easier to maintain.
3417 - Improved the type of some variables (particularly blocksize vars) for
3418 consistency and proper size.
3420 - Got rid of the uint64 type (which we didn't need).
3422 - Use a slightly more compatible set of core #include directives.
3424 - Defined int32 in a way that ensures that the build dies if we can't find a
3425 variable with at least 32 bits.
3427 ### PROTOCOL DIFFERENCES FOR VERSION 29:
3429 - A 16-bit flag-word is transmitted after every file-list index. This
3430 indicates what is changing between the sender and the receiver. The
3431 generator now transmits an index and a flag-word to indicate when dirs and
3432 symlinks have changed (instead of producing a message), which makes the
3433 outputting of the information more consistent and less prone to screen
3434 corruption (because the local receiver/sender is now outputting all the
3435 file-change info messages).
3437 - If a file is being hard-linked, the `ITEM_XNAME_FOLLOWS` bit is enabled in
3438 the flag-word and the name of the file that was linked immediately follows
3439 in vstring format (see below).
3441 - If a file is being transferred with an alternate-basis file, the
3442 `ITEM_BASIS_TYPE_FOLLOWS` bit is enabled in the flag-word and a single byte
3443 follows, indicating what type of basis file was chosen. If that indicates
3444 that a fuzzy-match was selected, the `ITEM_XNAME_FOLLOWS` bit is set in the
3445 flag-word and the name of the match in vstring format follows the basis
3446 byte. A vstring is a variable length string that has its size written prior
3447 to the string, and no terminating null. If the string is from 1-127 bytes,
3448 the length is a single byte. If it is from 128-32767 bytes, the length is
3449 written as ((len >> 8) | 0x80) followed by (len % 0x100).
3451 - The sending of exclude names is done using filter-rule syntax. This means
3452 that all names have a prefixed rule indicator, even excludes (which used to
3453 be sent as a bare pattern, when possible). The `-C` option will include the
3454 per-dir .cvsignore merge file in the list of filter rules so it is
3455 positioned correctly (unlike in some older transfer scenarios).
3457 - Rsync sorts the filename list in a different way: it sorts the subdir names
3458 after the non-subdir names for each dir's contents, and it always puts a
3459 dir's contents immediately after the dir's name in the list. (Previously an
3460 item named `foo.txt` would sort in between directory `foo/` and `foo/bar`.)
3462 - When talking to a protocol 29 rsync daemon, a list-only request is able to
3463 note this before the options are sent over the wire and the new
3464 `--list-only` option is included in the options.
3466 - When the `--stats` bytes are sent over the wire (or stored in a batch), they
3467 now include two elapsed-time values: one for how long it took to build the
3468 file-list, and one for how long it took to send it over the wire (each
3469 expressed in thousandths of a second).
3471 - When `--delete-excluded` is specified with some filter rules (AKA excludes),
3472 a client sender will now initiate a send of the rules to the receiver (older
3473 protocols used to omit the sending of excludes in this situation since there
3474 were no receiver-specific rules that survived `--delete-excluded` back
3475 then). Note that, as with all the filter-list sending, only items that are
3476 significant to the other side will actually be sent over the wire, so the
3477 filter-rule list that is sent in this scenario is often empty.
3479 - An index equal to the file-list count is sent as a keep-alive packet from
3480 the generator to the sender, which then forwards it on to the receiver. This
3481 normally invalid index is only a valid keep-alive packet if the 16-bit
3482 flag-word that follows it contains a single bit (`ITEM_IS_NEW`, which is
3483 normally an illegal flag to appear alone).
3485 - A protocol-29 batch file includes a bit for the setting of the `--dirs`
3486 option and for the setting of the `--compress` option. Also, the shell
3487 script created by `--write-batch` will use the `--filter` option instead of
3488 `--exclude-from` to capture any filter rules.
3492 - Handle an operating system that use mkdev() in place of makedev().
3494 - Improved configure to better handle cross-compiling.

3498 # NEWS for rsync 2.6.3 (30 Sep 2004)
3500 ## Changes in this version:
3504 - A bug in the `sanitize_path` routine (which affects a non-chrooted rsync
3505 daemon) could allow a user to craft a pathname that would get transformed
3506 into an absolute path for certain options (but not for file-transfer names).
3507 If you're running an rsync daemon with chroot disabled, **please upgrade**,
3508 ESPECIALLY if the user privs you run rsync under is anything above `nobody`.
3510 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
3512 - Please note that the 2-line footer (output when verbose) now uses the term
3513 `sent` instead of `wrote` and `received` instead of `read`. If you are not
3514 parsing the numeric values out of this footer, a script would be better off
3515 using the empty line prior to the footer as the indicator that the verbose
3518 - The output from the `--stats` option was similarly affected to change
3519 `written` to `sent` and `read` to `received`.
3521 - Rsync ensures that a filename that contains a newline gets mentioned with
3522 each newline transformed into a question mark (which prevents a filename
3523 from causing an empty line to be output).
3525 - The `backed up ...` message that is output when at least 2 `--verbose`
3526 options are specified is now the same both with and without the
3527 `--backup-dir` option.
3531 - Fixed a crash bug that might appear when `--delete` was used and multiple
3532 source directories were specified.
3534 - Fixed a 32-bit truncation of the file length when generating the checksums.
3536 - The `--backup` code no longer attempts to create some directories over and
3537 over again (generating warnings along the way).
3539 - Fixed a bug in the reading of the secrets file (by the daemon) and the
3540 password file (by the client): the files no longer need to be terminated by
3541 a newline for their content to be read in.
3543 - If a file has a read error on the sending side or the reconstructed data
3544 doesn't match the expected checksum (perhaps due to the basis file changing
3545 during the transfer), the receiver will no longer retain the resulting file
3546 unless the `--partial` option was specified. (Note: for the read-error
3547 detection to work, neither side can be older than 2.6.3 -- older receivers
3548 will always retain the file, and older senders don't tell the receiver that
3549 the file had a read error.)
3551 - If a file gets resent in a single transfer and the `--backup` option is
3552 enabled, rsync no longer performs a duplicate backup (it used to overwrite
3553 the original file in the backup area).
3555 - Files specified in the daemon's `exclude` or `exclude from` config items are
3556 now excluded from being uploaded (assuming that the module allows uploading
3557 at all) in addition to the old download exclusion.
3559 - Got rid of a potential hang in the receiver when near the end of a phase.
3561 - When using `--backup` without a `--backup-dir`, rsync no longer preserves
3562 the modify time on directories. This avoids confusing NFS.
3564 - When `--copy-links` (`-L`) is specified, we now output a separate error for
3565 a symlink that has no referent instead of claiming that a file `vanished`.
3567 - The `--copy-links` (`-L`) option no longer has the side-effect of telling
3568 the receiving side to follow symlinks. See the `--keep-dirlinks` option
3569 (mentioned below) for a way to specify that behavior.
3571 - Error messages from the daemon server's option-parsing (such as refused
3572 options) are now successfully transferred back to the client (the server
3573 used to fail to send the message because the socket wasn't in the right
3574 state for the message to get through).
3576 - Most transfer errors that occur during a daemon transfer are now returned to
3577 the user in addition to being logged (some messages are intended to be
3578 daemon-only and are not affected by this).
3580 - Fixed a bug in the daemon authentication code when using one of the
3581 batch-processing options.
3583 - We try to work around some buggy IPv6 implementations that fail to implement
3584 `IPV6_V6ONLY`. This should fix the `address in use` error that some daemons
3585 get when running on an OS with a buggy IPv6 implementation. Also, if the new
3586 code gets this error, we might suggest that the user specify `--ipv4` or
3587 `--ipv6` (if we think it will help).
3589 - When the remote rsync dies, make a better effort to recover any error
3590 messages it may have sent before dying (the local rsync used to just die
3591 with a socket-write error).
3593 - When using `--delete` and a `--backup-dir` that contains files that are
3594 hard-linked to their destination equivalents, rsync now makes sure that
3595 removed files really get removed (avoids a really weird rename() behavior).
3597 - Avoid a bogus run-time complaint about a lack of 64-bit integers when the
3598 int64 type is defined as an `off_t` and it actually has 64-bits.
3600 - Added a configure check for open64() without mkstemp64() so that we can
3601 avoid using mkstemp() when such a combination is encountered. This bypasses
3602 a problem writing out large temp files on OSes such as AIX and HP-UX.
3604 - Fixed an age-old crash problem with `--read-batch` on a local copy (rsync
3605 was improperly assuming `--whole-file` for the local copy).
3607 - When `--dry-run` (`-n`) is used and the destination directory does not
3608 exist, rsync now produces a correct report of files that would be sent
3609 instead of dying with a chdir() error.
3611 - Fixed a bug that could cause a slow-to-connect rsync daemon to die with an
3612 error instead of waiting for the connection to finish.
3614 - Fixed an ssh interaction that could cause output to be lost when the user
3615 chose to combine the output of rsync's stdout and stderr (e.g. using the
3618 - Fixed an option-parsing bug when `--files-from` got passed to a daemon.
3622 - Added the `--partial-dir=DIR` option that lets you specify where to
3623 (temporarily) put a partially transferred file (instead of overwriting the
3624 destination file). E.g. `--partial-dir=.rsync-partial` Also added support
3625 for the `RSYNC_PARTIAL_DIR` environment variable that, when found,
3626 transforms a regular `--partial` option (such as the convenient `-P` option)
3627 into one that also specifies a directory.
3629 - Added `--keep-dirlinks` (`-K`), which allows you to symlink a directory onto
3630 another partition on the receiving side and have rsync treat it as matching
3631 a normal directory from the sender.
3633 - Added the `--inplace` option that tells rsync to write each destination file
3634 without using a temporary file. The matching of existing data in the
3635 destination file can be severely limited by this, but there are also cases
3636 where this is more efficient (such as appending data). Use only when needed
3637 (see the manpage for more details).
3639 - Added the `write only` option for the daemon's config file.
3641 - Added long-option names for `-4` and `-6` (namely `--ipv4` and `--ipv6`) and
3642 documented all these options in the manpage.
3644 - Improved the handling of the `--bwlimit` option so that it's less bursty,
3645 more accurate, and works properly over a larger range of values.
3647 - The rsync daemon-over-ssh code now looks for `SSH_CONNECTION` and
3648 `SSH2_CLIENT` in addition to `SSH_CLIENT` to figure out the IP address.
3650 - Added the `--checksum-seed=N` option for advanced users.
3652 - Batch writing/reading has a brand-new implementation that is simpler, fixes
3653 a few weird problems with the old code (such as no longer sprinkling the
3654 batch files into different dirs or even onto different systems), and is much
3655 less intrusive into the code (making it easier to maintain for the future).
3656 The new code generates just one data file instead of three, which makes it
3657 possible to read the batch on stdin via a remote shell. Also, the old
3658 requirement of forcing the same fixed checksum-seed for all batch processing
3661 - If an rsync daemon has a module set with `list = no` (which hides its
3662 presence in the list of available modules), a user that fails to
3663 authenticate gets the same `unknown module` error that they would get if the
3664 module were actually unknown (while still logging the real error to the
3665 daemon's log file). This prevents fishing for module names.
3667 - The daemon's `refuse options` config item now allows you to match option
3668 names using wildcards and/or the single-letter option names.
3670 - Each transferred file now gets its permissions and modified-time updated
3671 before the temp-file gets moved into place. Previously, the finished file
3672 would have a very brief window where its permissions disallowed all group
3675 - Added the ability to parse a literal IPv6 address in an `rsync:` URL (e.g.
3676 rsync://[2001:638:500:101::21]:873/module/dir).
3678 - The daemon's wildcard expanding code can now handle more than 1000 filenames
3679 (it's now limited by memory instead of having a hard-wired limit).
3683 - Some cleanup in the exclude code has saved some per-exclude memory and made
3684 the code easier to maintain.
3686 - Improved the argv-overflow checking for a remote command that has a lot of
3689 - Use rsyserr() in the various places that were still calling rprintf() with
3690 strerror() as an arg.
3692 - If an rsync daemon is listening on multiple sockets (to handle both IPv4 and
3693 IPv6 to a single port), we now close all the unneeded file handles after we
3694 accept a connection (we used to close just one of them).
3696 - Optimized the handling of larger block sizes (rsync used to slow to a crawl
3697 if the block size got too large).
3699 - Optimized away a loop in `hash_search()`.
3701 - Some improvements to the `sanitize_path()` and `clean_fname()` functions
3702 makes them more efficient and produce better results (while still being
3703 compatible with the file-name cleaning that gets done on both sides when
3704 sending the file-list).
3706 - Got rid of `alloc_sanitize_path()` after adding a destination-buffer arg to
3707 `sanitize_path()` made it possible to put all the former's functionality
3710 - The file-list that is output when at least 4 verbose options are specified
3711 reports the uid value on the sender even when rsync is not running as root
3712 (since we might be sending to a root receiver).
3716 - Added a `gen` target to rebuild most of the generated files, including
3717 configure, config.h.in, the manpages, and proto.h.
3719 - If `make proto` doesn't find some changes in the prototypes, the proto.h
3720 file is left untouched (its time-stamp used to always be updated).
3722 - The variable `$STRIP` (that is optionally set by the install-strip target's
3723 rule) was changed to `$INSTALL_STRIP` because some systems have `$STRIP`
3724 already set in the environment.
3726 - Fixed a build problem when `SUPPORT_HARD_LINKS` isn't defined.
3728 - When cross-compiling, the gettimeofday() function is now assumed to be a
3729 modern version that takes two-args (since we can't test it).
3731 ### DEVELOPER RELATED:
3733 - The scripts in the testsuite dir were cleaned up a bit and a few new tests
3736 - Some new diffs were added to the patches dir, and some accepted ones were
3739 ------------------------------------------------------------------------------
3741 # NEWS for rsync 2.6.2 (30 Apr 2004)
3743 ## Changes in this version:
3747 - Fixed a major bug in the sorting of the filenames when `--relative` is used
3748 for some sources (just sources such as `/` and `/*` were affected). This fix
3749 ensures that we ask for the right file-list item when requesting changes
3752 - Rsync now checks the return value of the close() function to better report
3753 disk-full problems on an NFS file system.
3755 - Restored the old daemon-server behavior of logging error messages rather
3756 than returning them to the user. (A better long-term fix will be sought in
3759 - An obscure uninitialized-variable bug was fixed in the uid/gid code. (This
3760 bug probably had no ill effects.)
3764 - Got rid of the configure check for sys/sysctl.h (it wasn't used and was
3765 causing a problem on some systems). Also improved the
3766 broken-largefile-locking test to try to avoid failure due to an NFS
3769 - Fixed a compile problem on systems that don't define `AI_NUMERICHOST`.
3771 - Fixed a compile problem in the popt source for compilers that don't support
3774 ### DEVELOPER RELATED:
3776 - Improved the testsuite's `merge` test to work on OSF1.
3778 - Two new diffs were added to the patches dir.
3780 ------------------------------------------------------------------------------
3782 # NEWS for rsync 2.6.1 (26 Apr 2004)
3784 ## Changes in this version:
3786 ### PROTOCOL NUMBER:
3788 - The protocol number was changed to 28.
3792 - Paths sent to an rsync daemon are more thoroughly sanitized when chroot is
3793 not used. If you're running a non-read-only rsync daemon with chroot
3794 disabled, **please upgrade**, ESPECIALLY if the user privs you run rsync
3795 under is anything above `nobody`.
3799 - Lower memory use, more optimal transfer of data over the socket, and lower
3800 CPU usage (see the INTERNAL section for details).
3802 - The `RSYNC_PROXY` environment variable can now contain a `USER:PASS@` prefix
3803 before the `HOST:PORT` information. (Bardur Arantsson)
3805 - The `--progress` output now mentions how far along in the transfer we are,
3806 including both a count of files transferred and a percentage of the total
3807 file-count that we've processed. It also shows better
3808 current-rate-of-transfer and remaining-transfer-time values.
3810 - Documentation changes now attempt to describe some often misunderstood
3811 features more clearly.
3815 - When `-x` (`--one-file-system`) is combined with `-L` (`--copy-links`) or
3816 `--copy-unsafe-links,` no symlinked files are skipped, even if the referent
3817 file is on a different filesystem.
3819 - The `--link-dest` code now works properly for a non-root user when (1) the
3820 UIDs of the source and destination differ and `-o` was specified, or (2)
3821 when the group of the source can't be used on the destination and `-g` was
3824 - Fixed a bug in the handling of `-H` (hard-links) that might cause the
3825 expanded PATH/NAME value of the current item to get overwritten (due to an
3826 expanded-name caching bug).
3828 - We now reset the `new data has been sent` flag at the start of each file we
3829 send. This makes sure that an interrupted transfer with the `--partial`
3830 option set doesn't keep a shorter temp file than the current basis file when
3831 no new data has been transferred over the wire for that file.
3833 - Fixed a byte-order problem in `--batch-mode` on big-endian machines. (Jay
3836 - When using `--cvs-exclude`, the exclude items we get from a per-directory's
3837 .cvsignore file once again only affect that one directory (not all following
3838 directories too). The items are also now properly word-split and parsed
3839 without any +/- prefix parsing.
3841 - When specifying the USER@HOST: prefix for a file, the USER part can now
3842 contain an '@', if needed (i.e. the last '@' is used to find the HOST, not
3845 - Fixed some bugs in the handling of group IDs for non-root users: (1) It
3846 properly handles a group that the sender didn't have a name for (it would
3847 previously skip changing the group on any files in that group). (2) If
3848 `--numeric-ids` is used, rsync no longer attempts to set groups that the
3849 user doesn't have the permission to set.
3851 - Fixed the `refuse options` setting in the rsyncd.conf file.
3853 - Improved the `-x` (`--one-file-system`) flag's handling of any mount-point
3854 directories we encounter. It is both more optimal (in that it no longer does
3855 a useless scan of the contents of the mount-point dirs) and also fixes a
3856 bug where a remapped mount of the original filesystem could get discovered
3857 in a subdir we should be ignoring.
3859 - Rsync no longer discards a double-slash at the start of a filename when
3860 trying to open the file. It also no longer constructs names that start with
3861 a double slash (unless the user supplied them).
3863 - Path-specifying options to a daemon should now work the same with or without
3864 chroot turned on. Previously, such a option (such as `--link-dest`) would
3865 get its absolute path munged into a relative one if chroot was not on,
3866 making that setting fairly useless. Rsync now transforms the path into one
3867 that is based on the module's base dir when chroot is not enabled.
3869 - Fixed a compatibility problem interacting with older rsync versions that
3870 might send us an empty `--suffix` value without telling us that
3871 `--backup-dir` was specified.
3873 - The `hosts allow` option for a daemon-over-remote-shell process now has
3874 improved support for IPv6 addresses and a fix for systems that have a length
3875 field in their socket structs.
3877 - Fixed the ability to request an empty backup `--suffix` when sending files
3880 - Fixed an option-parsing bug when `--files-from` was sent to a server sender.
3884 - Most of the I/O is now buffered, which results in a pretty large speedup
3885 when running under MS Windows. (Craig Barratt)
3887 - Optimizations to the name-handling/comparing code have made some significant
3888 reductions in user-CPU time for large file sets.
3890 - Some cleanup of the variable types make the code more consistent.
3892 - Reduced memory requirements of hard link preservation. (J.W. Schultz)
3894 - Implemented a new algorithm for hard-link handling that speeds up the code
3895 significantly. (J.W. Schultz and Wayne Davison)
3897 - The `--hard-link` option now uses the first existing file in the group of
3898 linked files as the basis for the transfer. This prevents the sub-optimal
3899 transfer of a file's data when a new hardlink is added on the sending side
3900 and it sorts alphabetically earlier in the list than the files that are
3901 already present on the receiving side.
3903 - Dropped support for protocol versions less than 20 (2.3.0 released 15 Mar
3904 1999) and activated warnings for protocols less than 25 (2.5.0 released 23
3905 Aug 2001). (Wayne Davison and J.W. Schultz, severally)
3907 - More optimal data transmission for `--hard-links` (protocol 28).
3909 - More optimal data transmission for `--checksum` (protocol 28).
3911 - Less memory is used when `--checksum` is specified.
3913 - Less memory is used in the file list (a per-file savings).
3915 - The generator is now better about not modifying the file list during the
3916 transfer in order to avoid a copy-on-write memory bifurcation (on systems
3917 where fork() uses shared memory). Previously, rsync's shared memory would
3918 slowly become unshared, resulting in real memory usage nearly doubling on
3919 the receiving side by the end of the transfer. Now, as long as permissions
3920 are being preserved, the shared memory should remain that way for the entire
3923 - Changed hardlink info and `file_struct` + strings to use allocation pools.
3924 This reduces memory use for large file-sets and permits freeing memory to
3925 the OS. (J.W. Schultz)
3927 - The 2 pipes used between the receiver and generator processes (which are
3928 forked on the same machine) were reduced to 1 pipe and the protocol improved
3929 so that (1) it is now impossible to have the `redo` pipe fill up and hang
3930 rsync, and (2) trailing messages from the receiver don't get lost on their
3931 way through the generator over to the sender (which mainly affected
3932 hard-link messages and verbose `--stats` output).
3934 - Improved the internal uid/gid code to be more portable and a little more
3937 - The device numbers sent when using `--devices` are now sent as separate
3938 major/minor values with 32-bit accuracy (protocol 28). Previously, the
3939 copied devices were sent as a single 32-bit number. This will make
3940 inter-operation of 64-bit binaries more compatible with their 32-bit
3941 brethren (with both ends of the connection are using protocol 28). Note that
3942 optimizations in the binary protocol for sending the device numbers often
3943 results in fewer bytes being used than before, even though more precision is
3946 - Some cleanup of the exclude/include structures and its code made things
3947 clearer (internally), simpler, and more efficient.
3949 - The reading & writing of the file-list in batch-mode is now handled by the
3950 same code that sends & receives the list over the wire. This makes it much
3951 easier to maintain. (Note that the batch code is still considered to be
3956 - The configure script now accepts `--with-rsyncd-conf=PATH` to override the
3957 default value of the /etc/rsyncd.conf file.
3959 - Fixed configure bug when running `./configure --disable-ipv6`.
3961 - Fixed compilation problem on Tru64 Unix (having to do with `sockaddr.sa_len`
3962 and `sockaddr.sin_len`).
3964 ### DEVELOPER RELATED:
3966 - Fixed `make test` bug when build dir is not the source dir.
3968 - Added a couple extra diffs in the `patches` dir, removed the ones that got
3969 applied, and rebuilt the rest.
3971 ------------------------------------------------------------------------------
3973 # NEWS for rsync 2.6.0 (1 Jan 2004)
3975 ## Changes in this version:
3977 ### PROTOCOL NUMBER:
3979 - The protocol number was changed to 27. The maximum accepted protocol number
3980 was increased from 30 to 40.
3984 - `ssh` is now the default remote shell for rsync. If you want to change this,
3985 configure like this: `./configure --with-rsh=rsh`.
3987 - Added `--files-from`, `--no-relative`, `--no-implied-dirs`, and `--from0`.
3988 Note that `--from0` affects the line-ending character for all the files read
3989 by the `--*-from` options. (Wayne Davison)
3991 - Length of csum2 is now per-file starting with protocol version
3994 - Per-file dynamic block size is now sqrt(file length). The per-file checksum
3995 size is determined according to an algorithm provided by Donovan Baarda
3996 which reduces the probability of rsync algorithm corrupting data and falling
3997 back using the whole md4 checksums. (J.W. Schultz, Donovan Baarda)
3999 - The `--stats` option no longer includes the (debug) malloc summary unless
4000 the verbose option was specified at least twice.
4002 - Added a new error/warning code for when files vanish from the sending side.
4003 Made vanished source files not interfere with the file-deletion pass when
4004 `--delete-after` was specified.
4006 - Various trailing-info sections are now preceded by a newline.
4010 - Fixed several exclude/include matching bugs when using wild-cards. This has
4011 a several user-visible effects, all of which make the matching more
4012 consistent and intuitive. This should hopefully not cause anyone problems
4013 since it makes the matching work more like what people are expecting. (Wayne
4016 - A pattern with a `**` no longer causes a `*` to match slashes. For example,
4017 with `/*/foo/**`, `foo` must be 2 levels deep. [If your string has BOTH `*`
4018 and `**` wildcards, changing the `*` wildcards to `**` will provide the old
4019 behavior in all versions.]
4021 - `**/foo` now matches at the base of the transfer (like /foo does). [Use
4022 `/**/foo` to get the old behavior in all versions.]
4024 - A non-anchored wildcard term floats to match beyond the base of the
4025 transfer. E.g. `CVS/R*` matches at the end of the path, just like the
4026 non-wildcard term `CVS/Root` does. [Use `/CVS/R*` to get the old behavior in
4029 - Including a `**` in the match term causes it to be matched against the
4030 entire path, not just the name portion, even if there aren't any interior
4031 slashes in the term. E.g. `foo**bar` would exclude `/path/foo-bar` (just
4032 like before) as well as `/foo-path/baz-bar` (unlike before). [Use `foo*bar`
4033 to get the old behavior in all versions.]
4035 - The exclude list specified in the daemon's config file is now properly
4036 applied to the pulled items no matter how deep the user's file-args are in
4037 the source tree. (Wayne Davison)
4039 - For protocol version >= 27, `mdfour_tail()` is called when the block size
4040 (including `checksum_seed`) is a multiple of 64. Previously it was not
4041 called, giving the wrong MD4 checksum. (Craig Barratt)
4043 - For protocol version >= 27, a 64 bit bit counter is used in mdfour.c as
4044 required by the RFC. Previously only a 32 bit bit counter was used, causing
4045 incorrect MD4 file checksums for file sizes >= 512MB - 4. (Craig Barratt)
4047 - Fixed a crash bug when interacting with older rsync versions and multiple
4048 files of the same name are destined for the same dir. (Wayne Davison)
4050 - Keep tmp names from overflowing MAXPATHLEN.
4052 - Make `--link-dest` honor the absence of `-p`, `-o`, and `-g`.
4054 - Made rsync treat a trailing slash in the destination in a more consistent
4057 - Fixed file I/O error detection. (John Van Essen)
4059 - Fixed bogus `malformed address {hostname}` message in rsyncd log when
4060 checking IP address against hostnames from `hosts allow` and `hosts deny`
4061 parameters in config file.
4063 - Print heap statistics when verbose >= 2 instead of when >= 1.
4065 - Fixed a compression (`-z`) bug when syncing a mostly-matching file that
4066 contains already-compressed data. (Yasuoka Masahiko and Wayne Davison)
4068 - Fixed a bug in the `--backup` code that could cause deleted files to not get
4071 - When the backup code makes new directories, create them with mode 0700
4072 instead of 0755 (since the directory permissions in the backup tree are not
4073 yet copied from the main tree).
4075 - Call setgroups() in a more portable manner.
4077 - Improved file-related error messages to better indicate exactly what
4078 pathname failed. (Wayne Davison)
4080 - Fixed some bugs in the handling of `--delete` and `--exclude` when using the
4081 `--relative` (`-R`) option. (Wayne Davison)
4083 - Fixed bug that prevented regular files from replacing special files and
4084 caused a directory in `--link-dest` or `--compare-dest` to block the
4085 creation of a file with the same path. A directory still cannot be replaced
4086 by a regular file unless `--delete` specified. (J.W. Schultz)
4088 - Detect and report when open or opendir succeed but read and readdir fail
4089 caused by network filesystem issues and truncated files. (David Norwood,
4090 Michael Brown, J.W. Schultz)
4092 - Added a fix that should give ssh time to restore the tty settings if the
4093 user presses Ctrl-C at an ssh password prompt.
4097 - Eliminated vestigial support for old versions that we stopped supporting.
4100 - Simplified some of the option-parsing code. (Wayne Davison)
4102 - Some cleanup made to the exclude code, as well as some new defines added to
4103 enhance readability. (Wayne Davison)
4105 - Changed the protocol-version code so that it can interact at a lower
4106 protocol level than the maximum supported by both sides. Added an
4107 undocumented option, `--protocol=N`, to force the value we advertise to the
4108 other side (primarily for testing purposes). (Wayne Davison)

4121 ------------------------------------------------------------------------------
4123 # NEWS for rsync 2.5.6, aka "the dwd-between-jobs release" (26 Jan 2003)
4125 ## Changes in this version:
4129 - The `--delete-after` option now implies `--delete`. (Wayne Davison)
4131 - The `--suffix` option can now be used with `--backup-dir`. (Michael
4134 - Combining `::` syntax with the `--rsh`/`-e` option now uses the specified
4135 remote-shell as a transport to talk to a (newly-spawned) server-daemon. This
4136 allows someone to use daemon features, such as modules, over a secure
4137 protocol, such as ssh. (JD Paul)
4139 - The rsync:// syntax for daemon connections is now accepted in the
4142 - If the file name given to `--include-from` or `--exclude-from` is `-`, rsync
4143 will read from standard input. (J.W. Schultz)
4145 - New option `--link-dest` which is like `--compare-dest` except that
4146 unchanged files are hard-linked in to the destination directory. (J.W.
4149 - Don't report an error if an excluded file disappears during an rsync run.
4150 (Eugene Chupriyanov and Bo Kersey)
4152 - Added .svn to `--cvs-exclude` list to support subversion. (Jon Middleton)
4154 - Properly support IPv6 addresses in the rsyncd.conf `hosts allow` and `hosts
4155 deny` fields. (Hideaki Yoshifuji)
4157 - Changed exclude file handling to permit DOS or MAC style line terminations.
4160 - Ignore errors from chmod when `-p`/`-a`/`--preserve-perms` is not set.
4165 - Fix `forward name lookup failed` errors on AIX 4.3.3. (John L. Allen, Martin
4168 - Generate each file's rolling-checksum data as we send it, not in a separate
4169 (memory-eating) pass before hand. This prevents timeout errors on really
4170 large files. (Stefan Nehlsen)
4172 - Fix compilation on Tru64. (Albert Chin, Zoong Pham)
4174 - Better handling of some client-server errors. (Martin Pool)
4176 - Fixed a crash that would occur when sending a list of files that contains a
4177 duplicate name (if it sorts to the end of the file list) and using
4178 `--delete`. (Wayne Davison)
4180 - Fixed the file-name duplicate-removal code when dealing with multiple dups
4181 in a row. (Wayne Davison)
4183 - Fixed a bug that caused rsync to lose the exit status of its child processes
4184 and sometimes return an exit code of 0 instead of showing an error. (David
4185 R. Staples, Dave Dykstra)
4187 - Fixed bug in `--copy-unsafe-links` that caused it to be completely broken.
4190 - Prevent infinite recursion in cleanup code under certain circumstances.
4191 (Sviatoslav Sviridov and Marc Espie)
4193 - Fixed a bug that prevented rsync from creating intervening directories when
4194 `--relative-paths`/`-R` is set. (Craig Barratt)
4196 - Prevent `Connection reset by peer` messages from Cygwin. (Randy O'Meara)
4200 - Many code cleanups and improved internal documentation. (Martin Pool, Nelson
4203 - Portability fixes. (Dave Dykstra and Wayne Davison)
4205 - More test cases. (Martin Pool)
4207 - Some test-case fixes. (Brian Poole, Wayne Davison)
4209 - Updated included popt to the latest vendor drop, version 1.6.4. (Jos
4212 - Updated config.guess and config.sub to latest versions; this means rsync
4213 should build on more platforms. (Paul Green)
4215 ------------------------------------------------------------------------------
4217 # NEWS for rsync 2.5.5, aka Snowy River (2 Apr 2002)
4219 ## Changes in this version:
4223 - With `--progress`, when a transfer is complete show the time taken;
4224 otherwise show expected time to complete. (Cameron Simpson)
4226 - Make `make install-strip` works properly, and `make install` accepts a
4227 DESTDIR variable for help in building binary packages. (Peter
4228 Breitenlohner, Greg Louis)
4230 - If configured with `--enable-maintainer-mode`, then on receipt of a fatal
4231 signal rsync will try to open an xterm running gdb, similarly to Samba's
4232 `panic action` or GNOME's bug-buddy. (Martin Pool)
4236 - Fix situation where failure to fork (e.g. because out of process slots)
4237 would cause rsync to kill all processes owned by the current user. Yes,
4238 really! (Paul Haas, Martin Pool)
4240 - Fix test suite on Solaris. (Jos Backus, Martin Pool)
4242 - Fix minor memory leak in socket code. (Dave Dykstra, Martin Pool.)
4244 - Fix `--whole-file` problem that caused it to be the default even for remote
4245 connections. (Martin Pool, Frank Schulz)
4247 - Work around bug in Mac OS X mkdir(2), which cannot handle trailing slashes.
4248 <http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html> (Martin
4251 - Improved network error handling. (Greg A. Woods)
4253 ------------------------------------------------------------------------------
4255 # NEWS for rsync 2.5.4, aka "Imitation lizard skin" (13 Mar 2002)
4257 ## Changes in this version:
4261 - Additional fix for zlib double-free bug. (Martin Pool, Andrew Tridgell) (CVE
4266 - Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus) (Note that
4267 rsync still uses a custom version of zlib; you can not just link against a
4268 system library. See zlib/README.rsync)
4270 - Additional test cases for `--compress`. (Martin Pool)
4272 ------------------------------------------------------------------------------
4274 # NEWS for rsync 2.5.3, aka "Happy 26" (11 Mar 2002)
4276 ## Changes in this version:
4280 - Make sure that supplementary groups are removed from a server
4281 process after changing uid and gid. (Ethan Benson) (Debian bug
4282 #132272, CVE CAN-2002-0080)
4286 - Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE CAN-2002-0059)
4288 - Fixed problem that in many cases caused the error message unexpected read
4289 size of 0 in `map_ptr` and resulted in the wrong data being copied.
4291 - Fixed compilation errors on some systems caused by the use of `unsigned
4294 - Fixed problem on systems such as Sunos4 that do not support realloc on a
4295 NULL pointer; error was 'out of memory in "flist_expand"'.
4297 - Fix for rsync server processes hanging around after the client unexpectedly
4298 disconnects. (Colin Walters) (Debian bug #128632)
4300 - Cope with BSD systems on which mkdir() will not accept a trailing slash.
4304 - Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that rsync still uses
4305 a custom version of zlib; you can not just link against a system library.
4306 See zlib/README.rsync)
4308 - Command to initiate connections is only shown with `-vv`, rather than `-v`
4309 as in 2.5.2. Output from plain `-v` is more similar to what was historically
4310 used so as not to break scripts that try to parse the output.
4312 - Added `--no-whole-file` and `--no-blocking-io` options (Dave Dykstra)
4314 - Made the `--write-batch` and `--read-batch` options actually work and added
4315 documentation in the manpage (Jos Backus)
4317 - If the daemon is unable to fork a child to accept a connection, print an
4318 error message. (Colin Walters)
4320 ------------------------------------------------------------------------------
4322 # NEWS for rsync 2.5.2 (26 Jan 2002)
4324 ## Changes in this version:
4328 - Signedness security patch from Sebastian Krahmer <krahmer@suse.de> -- in
4329 some cases we were not sufficiently careful about reading integers from the
4332 ### PROTOCOL NUMBER:
4334 - The protocol number was changed to 26.
4338 - Fix possible string mangling in log files.
4340 - Fix for setting local address of outgoing sockets.
4342 - Better handling of hardlinks and devices on platforms with 64-bit `dev_t` or
4345 - Name resolution on machines supporting IPv6 is improved.
4347 - Fix for device nodes. (dann frazier) (Debian #129135)
4351 - With `-v`, rsync now shows the command used to initiate an ssh/rsh
4354 - `--statistics` now shows memory heap usage on platforms that support
4357 - "The Ted T'so school of program optimization": make progress visible and
4358 people will think it's faster. (With `--progress`, rsync will show you how
4359 many files it has seen as it builds the `file_list`, giving some indication
4360 that it has not hung.)
4362 - Improvements to batch mode support. This is still experimental but testing
4363 would be welcome. (Jos Backus)
4365 - New `--ignore-existing` option, patch previously distributed with Vipul's
4366 Razor. (Debian #124286)
4368 ------------------------------------------------------------------------------
4370 # NEWS for rsync 2.5.1 (3 Jan 2002)
4372 ## Changes in this version:
4376 - Fix for segfault in `--daemon` mode configuration parser. (Paul Mackerras)
4378 - Correct `string<->address` parsing for both IPv4 and 6. (YOSHIFUJI Hideaki,
4379 SUMIKAWA Munechika and Jun-ichiro `itojun` Hagino)
4381 - Various fixes for IPv6 support. (Dave Dykstra)
4383 - rsync.1 typo fix. (Matt Kraai)
4385 - Test suite typo fixes. (Tom Schmidt)
4387 - rsync.1 grammar and clarity improvements. (Edward Welbourne)
4389 - Correction to ./configure tests for `inet_ntop`. (Jeff Garzik)
4393 - `--progress` and `-P` now show estimated data transfer rate (in a multiple
4394 of bytes/s) and estimated time to completion. (Rik Faith)
4396 - `--no-detach` option, required to run as a W32 service and also useful when
4397 running on Unix under daemontools, AIX's SRC, or a debugger. (Max Bowsher,
4400 - Clearer error messages for some conditions.
4402 ------------------------------------------------------------------------------
4404 # NEWS for rsync 2.5.0 (30 Nov 2001)
4406 ## Changes in this version:
4408 ### PROTOCOL NUMBER:
4410 - The protocol number was changed to 25.
4414 - Martin Pool <mbp@samba.org> is now a co-maintainer.
4418 - Support for LSB-compliant packaging <http://www.linuxbase.org/>
4420 - Shell wildcards are allowed in `auth users` lines.
4422 - Merged UNC rsync+ patch to support creation of standalone patch sets. By
4423 Bert J. Dempsey and Debra Weiss, updated by Jos Backus.
4424 <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
4426 - IPv6 support based on a patch from KAME.net, on systems including modern
4427 versions of Linux, Solaris, and HP-UX. Also includes IPv6 compatibility
4428 functions for old OSs by the Internet Software Consortium, Paul Vixie, the
4429 OpenSSH portability project, and OpenBSD.
4433 - Include/exclude cluestick: with `-vv`, print out whether files are included
4434 or excluded and why.
4436 - Many error messages have more friendly explanations and more details.
4438 - Manual page improvements plus scanty protocol documentation.
4440 - When running as `--daemon` in the background and using a `log file`
4441 rsyncd.conf directive, close the log file every time it is open when going
4442 to sleep on the socket. This allows the log file to get cleaned out by
4445 - Change to using libpopt rather than getopt for processing options. This
4446 makes the code cleaner and the behaviour more consistent across platforms.
4447 popt is included and built if not installed on the platform.
4449 - More details in `--version`, including note about whether 64-bit files,
4450 symlinks and hardlinks are supported.
4452 - MD4 code may use less CPU cycles.
4454 - Use mkstemp on systems where it is secure. If we use mktemp, explain that we
4455 do it in a secure way.
4457 - `--whole-file` is the default when source and target are on the local
4462 - Fix for various bugs causing rsync to hang.
4464 - Attempt to fix Large File Summit support on AIX.
4466 - Attempt to fix error handling lockup bug.
4468 - Give a non-0 exit code if **any** of the files we have been asked to
4469 transfer fail to transfer.
4471 - For log messages containing ridiculously long strings that might overflow a
4472 buffer rsync no longer aborts, but rather prints an ellipsis at the end of
4473 the string. (Patch from Ed Santiago.)
4477 - Improved support for UNICOS (tested on Cray T3E and Cray SV1)
4479 - autoconf2.52 (or later) is now required to rebuild the autoconf scripts. It
4480 is not required to simply build rsync.
4482 - Platforms thought to work in this release:
