1 NEWS for rsync 2.6.9 (6 Nov 2006)
2 Protocol: 29 (unchanged)
7 - If rsync is interrupted via a handled signal (such as SIGINT), it will
8 once again clean-up its temp file from the destination dir.
10 - Fixed an overzealous sanitizing bug in the handling of the --link-dest,
11 --copy-dest, and --compare-dest options to a daemon without chroot: if
12 the copy's destination dir is deeper than the top of the module's path,
13 these options now accept a safe number of parent-dir (../) references
14 (since these options are relative to the destination dir). The old code
15 incorrectly chopped off all "../" prefixes for these options, no matter
16 how deep the destination directory was in the module's hierarchy.
18 - Fixed a bug where a deferred info/error/log message could get sent
19 directly to the sender instead of being handled by rwrite() in the
20 generator. This fixes an "unexpected tag 3" fatal error, and should
21 also fix a potential problem where a deferred info/error message from
22 the receiver might bypass the log file and get sent only to the client
23 process. (These problems could only affect an rsync daemon that was
26 - Fixed a bug when --inplace was combined with a --*-dest option and we
27 update a file's data using an alternate basis file. The code now
28 notices that it needs to copy the matching data from the basis file
29 instead of (wrongly) assuming that it was already present in the file.
31 - Fixed a bug where using --dry-run with a --*-dest option with a path
32 relative to a directory that does not yet exist: the affected option
33 gets its proper path value so that the output of the dry-run is right.
35 - Fixed a bug in the %f logfile escape when receiving files: the
36 destination path is now included in the output (e.g. you can now tell
37 when a user specifies a subdir inside a module).
39 - If the receiving side fails to create a directory, it will now skip
40 trying to update everything that is inside that directory.
42 - If --link-dest is specified with --checksum but without --times, rsync
43 will now allow a hard-link to be created to a matching link-dest file
44 even when the file's modify-time doesn't match the server's file.
46 - The daemon now calls more timezone-using functions prior to doing a
47 chroot. This should help some C libraries to generate proper timestamps
48 from inside a chrooted daemon (and to not try to access /etc/timezone
51 - Fixed a bug in the handling of an absolute --partial-dir=ABS_PATH option:
52 it now deletes an alternate basis file from the partial-dir that was used
53 to successfully update a destination file.
55 - Fixed a bug in the handling of --delete-excluded when using a per-dir
56 merge file: the merge file is now honored on the receiving side, and
57 only its unqualified include/exclude commands are ignored (just as is
58 done for global include/excludes).
60 - Fixed a recent bug where --delete was not working when transferring from
61 the root (/) of the filesystem with --relative enabled.
63 - Fixed a recent bug where an --exclude='*' could affect the root (/) of
64 the filesystem with --relative enabled.
66 - When --inplace creates a file, it is now created with owner read/write
67 permissions (0600) instead of no permissions at all. This avoids a
68 problem continuing a transfer that was interrupted (since --inplace
69 will not update a file that has no write permissions).
71 - If either --remove-source-files or --remove-sent-files is enabled and we
72 are unable to remove the source file, rsync now outputs an error.
74 - Fixed a bug in the daemon's "incoming chmod" rule: newly-created
75 directories no longer get the 'F' (file) rules applied to them.
77 - Fixed an infinite loop bug when a filter rule was rejected due to being
80 - When the server receives a --partial-dir option from the client, it no
81 longer runs the client-side code that adds an assumed filter rule (since
82 the client will be sending us the rules in the usual manner, and they
83 may have chosen to override the auto-added rule).
87 - Added the --log-file=FILE and --log-file-format=FORMAT options. These
88 can be used to tell any rsync to output what it is doing to a log file.
89 They work with a client rsync, a non-daemon server rsync (see the man
90 page for instructions), and also allows the overriding of rsyncd.conf
91 settings when starting a daemon.
93 - The --log-format option was renamed to be --out-format to avoid confusing
94 it with affecting the log-file output. (The old option remains as an
95 alias for the new to preserve backward compatibility.)
97 - Made "log file" and "syslog facility" settable on a per-module basis in
98 the daemon's config file.
100 - Added the --remove-source-files option as a replacement for the (now
101 deprecated) --remove-sent-files option. This new option removes all
102 non-dirs from the source directories, even if the file was already
103 up-to-date. This fixes a problem where interrupting an rsync that
104 was using --remove-sent-files and restarting it could leave behind
105 a file that the earlier rsync synchronized, but didn't get to remove.
106 (The deprecated --remove-sent-files is still understood for now, and
107 still behaves in the same way as before.)
109 - Added the option --no-motd to suppress the message-of-the-day output
110 from a daemon when doing a copy. (See the manpage for a caveat.)
112 - Added a new environment variable to the pre-/post-xfer exec commands (in
113 the daemon's config file): RSYNC_PID. This value will be the same in
114 both the pre- and post-xfer commands, so it can be used if the pre-xfer
115 command wants to cache some arg/request info for the post-xfer command.
119 - Did a code audit using IBM's code-checker program and made several
120 changes, including: replacing most of the strcpy() and sprintf()
121 calls with strlcpy(), snprintf(), and memcpy(), adding a 0-value to
122 an enum that had been intermingling a literal 0 with the defined enum
123 values, silencing some uninitialized memory checks, marking some
124 functions with a "noreturn" attribute, and changing an "if" that
125 could never succeed on some platforms into a pre-processor directive
126 that conditionally compiles the code.
128 - Fixed a potential bug in f_name_cmp() when both the args are a
129 top-level "." dir (which doesn't happen in normal operations).
131 - Changed exit_cleanup() so that it can never return instead of exit.
132 The old code might return if it found the exit_cleanup() function
133 was being called recursively. The new code is segmented so that
134 any recursive calls move on to the next step of the exit-processing.
136 - The macro WIFEXITED(stat) will now be defined if the OS didn't already
141 - The acls.diff and xattrs.diff patches have received a bunch of work to
142 make them much closer to being acceptable in the main distribution.
143 The xattrs patch also has some preliminary Mac OS X and FreeBSD
144 compatibility code that various system types to exchange extended
147 - A new diff in the patches dir, fake-root.diff, allows rsync to
148 maintain a backup hierarchy with full owner, group, and device info
149 without actually running as root. It does this using a special
150 extended attribute, so it depends on xattrs.diff (which depends on
153 - The rsync.yo and rsyncd.conf.yo files have been updated to work
154 better with the latest yodl 2.x releases.
156 - Updated config.guess and config.sub to their 2006-07-02 versions.
158 - Updated various files to include the latest FSF address and to have
159 consistent opening comments.
162 NEWS for rsync 2.6.8 (22 Apr 2006)
163 Protocol: 29 (unchanged)
168 - Fixed a bug in the exclude code where an anchored exclude without any
169 wildcards fails to match an absolute source arg, but only when --relative
172 - Improved the I/O code for the generator to fix a potential hang when the
173 receiver gets an EOF on the socket but the generator's select() call
174 never indicates that the socket is writable for it to be notified about
175 the EOF. (This can happen when using stunnel).
177 - Fixed a problem with the file-reading code where a failed read (such as
178 that caused by a bad sector) would not advance the file's read-position
179 beyond the failed read's data.
181 - Fixed a logging bug where the "log file" directive was not being honored
182 in a single-use daemon (one spawned by a remote-shell connection or by
185 - If rsync cannot honor the --delete option, we output an error and exit
186 instead of silently ignoring the option.
188 - Fixed a bug in the --link-dest code that prevented special files (such as
189 fifos) from being linked.
191 - The ability to hard-link symlinks and special files is now determined at
192 configure time instead of at runtime. This fixes a bug with --link-dest
193 creating a hard-link to a symlink's referent on a BSD system.
197 - In daemon mode, if rsync fails to bind to the requested port, the
198 error(s) returned by socket() and/or bind() are now logged.
200 - When we output a fatal error, we now output the version of rsync in the
203 - Improved the documentation for the --owner and --group options.
205 - The rsyncstats script in "support" has an improved line-parsing regex
206 that is easier to read and also makes it to parse syslog-generated lines.
208 - A new script in "support": file-attr-restore, can be used to restore the
209 attributes of a file-set (the permissions, ownership, and group info)
210 taken from the cached output of a "find ARG... -ls" command.
214 - Removed the unused function write_int_named(), the unused variable
215 io_read_phase, and the rarely used variable io_write_phase. This also
216 elides the confusing 'phase "unknown"' part of one error message.
218 - Removed two unused configure checks and two related (also unused)
219 compatibility functions.
221 - The xattrs.diff patch received a security fix that prevents a potential
222 buffer overflow in the receive_xattr() code.
224 - The acls.diff patch has been improved quite a bit, with more to come.
226 - A new patch was added: log-file.diff. This contains an early version of
227 a future option, --log-file=FILE, that will allow any rsync to log its
228 actions to a file (something that only a daemon supports at present).
231 NEWS for rsync 2.6.7 (11 Mar 2006)
232 Protocol: 29 (unchanged)
237 - The letter 'D' in the itemized output was being used for both devices
238 (character or block) as well as other special files (such as fifos and
239 named sockets). This has changed to separate non-device special files
240 under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
241 "--specials" option, below.
243 - The way rsync escapes unreadable characters has changed. First, rsync
244 now has support for recognizing valid multibyte character sequences in
245 your current locale, allowing it to escape fewer characters than before
246 for a locale such as UTF-8. Second, it now uses an escape idiom of
247 "\#123", which is the literal string "\#" followed by exactly 3 octal
248 digits. Rsync no longer doubles a backslash character in a filename
249 (e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
250 escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
251 (e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
252 the --8-bit-output (-8) option, mentioned below.
254 Script writers: the local rsync is the one that outputs escaped names,
255 so if you need to support unescaping of filenames for older rsyncs, I'd
256 suggest that you parse the output of "rsync --version" and only use the
257 old unescaping rules for 2.6.5 and 2.6.6.
261 - Fixed a really old bug that caused --checksum (-c) to checksum all the
262 files encountered during the delete scan (ouch).
264 - Fixed a potential hang in a remote generator: when the receiver gets a
265 read-error on the socket, it now signals the generator about this so that
266 the generator does not try to send any of the terminating error messages
267 to the client (avoiding a potential hang in some setups).
269 - Made hard-links work with symlinks and devices again.
271 - If the sender gets an early EOF reading a source file, we propagate this
272 error to the receiver so that it can discard the file and try requesting
273 it again (which is the existing behavior for other kinds of read errors).
275 - If a device-file/special-file changes permissions, rsync now updates the
276 permissions without recreating the file.
278 - If the user specifies a remote-host for both the source and destination,
279 we now output a syntax error rather than trying to open the destination
280 hostspec as a filename.
282 - When --inplace creates a new destination file, rsync now creates it with
283 permissions 0600 instead of 0000 -- this makes restarting possible when
284 the transfer gets interrupted in the middle of sending a new file.
286 - Reject the combination of --inplace and --sparse since the sparse-output
287 algorithm doesn't work when overwriting existing data.
289 - Fixed the directory name in the error that is output when pop_dir()
292 - Really fixed the parsing of a "!" entry in .cvsignore files this time.
294 - If the generator gets a stat() error on a file, output it (this used to
295 require at least -vv for the error to be seen).
297 - If waitpid() fails or the child rsync didn't exit cleanly, we now handle
298 the exit status properly and generate a better error.
300 - Fixed some glitches in the double-verbose output when using --copy-dest,
301 --link-dest, or --compare-dest. Also improved how the verbose output
302 handles hard-links (within the transfer) that had an up-to-date alternate
303 "dest" file, and copied files (via --copy-dest).
305 - Fixed the matching of the dont-compress items (e.g. *.gz) against files
306 that have a path component containing a slash.
308 - If code reading a filter/exclude file an EINTR error, rsync now clears
309 the error flag on the file handle so it can keep on reading.
311 - If --relative is active, the sending side cleans up trailing "/" or "/."
312 suffixes to avoid triggering a bug in older rsync versions. Also, we now
313 reject a ".." dir if it would be sent as a relative dir.
315 - If a non-directory is in the way of a directory and rsync is run with
316 --dry-run and --delete, rsync no longer complains about not being able
317 to opendir() the not-yet present directory.
319 - When --list-only is used and a non-existent local destination dir was
320 also specified as a destination, rsync no longer generates a warning
321 about being unable to create the missing directory.
323 - Fixed some problems with --relative --no-implied-dirs when the
324 destination directory did not yet exist: we can now create a symlink or
325 device when it is the first thing in the missing dir, and --fuzzy no
326 longer complains about being unable to open the missing dir.
328 - Fixed a bug where the --copy-links option would not affect implied
329 directories without --copy-unsafe-links (see --relative).
331 - Got rid of the need for --force to be used in some circumstances with
332 --delete-after (making it consistent with --delete-before/-during).
334 - Rsync now ignores the SIGXFSZ signal, just in case your OS sends this
335 when a file is too large (rsync handles the write error).
337 - Fixed a bug in the Proxy-Authorization header's base64-encoded value: it
338 was not properly padded with trailing '=' chars. This only affects a
339 user that need to use a password-authenticated proxy for an outgoing
340 daemon-rsync connection.
342 - If we're transferring an empty directory to a new name, rsync no longer
343 forces S_IWUSR if it wasn't already set, nor does it accidentally leave
346 - Fixed a bug in the debug output (-vvvvv) that could mention the wrong
347 checksum for the current file offset.
349 - Rsync no longer allows a single directory to be copied over a non-
350 directory destination arg.
354 - Added the --append option that makes rsync append data onto files that
355 are longer on the source than the destination (this includes new files).
357 - Added the --min-size=SIZE option to exclude small files from the
360 - Added the --compress-level option to allow you to set how aggressive
361 rsync's compression should be (this option implies --compress).
363 - Enhanced the parsing of the SIZE value for --min-size and --max-size to
364 allow easy entry of multiples of 1000 (instead of just multiples of 1024)
365 and off-by-one values too (e.g. --max-size=8mb-1).
367 - Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
368 high-bit characters that it thinks are unreadable in the current locale.
370 - The new option --human-readable (-h) changes the output of --progress,
371 --stats, and the end-of-run summary to be easier to read. If repeated,
372 the units become powers of 1024 instead of powers of 1000. (The old
373 meaning of -h, as a shorthand for --help, still works as long as you
374 just use it on its own, as in "rsync -h".)
376 - If lutimes() and/or lchmod() are around, use them to allow the
377 preservation of attributes on symlinks.
379 - The --link-dest option now affects symlinks and devices (when possible).
381 - Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
382 "post-xfer exec". These allow a command to be specified on a per-module
383 basis that will be run before and/or after a daemon-mode transfer. (See
384 the man page for a list of the environment variables that are set with
385 information about the transfer.)
387 - When using the --relative option, you can now insert a dot dir in
388 the source path to indicate where the replication of the source dirs
389 should start. For example, if you specify a source path of
390 rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
391 replicate the "baz/dir" part of the source path (note: a trailing
392 dot dir is unaffected unless it also has a trailing slash).
394 - Added some new --no-FOO options that make it easier to override unwanted
395 implied or default options. For example, "-a --no-o" (aka "--archive
396 --no-owner") can be used to turn off the preservation of file ownership
397 that is implied by -a.
399 - Added the --chmod=MODE option that allows the destination permissions to
400 be changed from the source permissions. E.g. --chmod=g+w,o-rwx
402 - Added the "incoming chmod" and "outgoing chmod" daemon options that allow
403 a module to specify what permissions changes should be applied to all
404 files copied to and from the daemon.
406 - Allow the --temp-dir option to be specified when starting a daemon, which
407 sets the default temporary directory for incoming files.
409 - If --delete is combined with --dirs without --recursive, rsync will now
410 delete in any directory whose content is being synchronized.
412 - If --backup is combined with --delete without --backup-dir (and without
413 --delete-excluded), we add a "protect" filter-rule to ensure that files
414 with the backup suffix are not deleted.
416 - The file-count stats that are output by --progress were improved to
417 better indicate what the numbers mean. For instance, the output:
418 "(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
419 to be transferred, and we still need to check 8383 more files out of
422 - The include/exclude code now allows a dir/*** directive (with 3 trailing
423 stars) to match both the dir itself as well as all the content below the
424 dir (dir/** would not match the dir).
426 - Added the --prune-empty-dirs (-m) option that makes the receiving rsync
427 discard empty chains of directories from the file-list. This makes it
428 easier to selectively copy files from a source hierarchy and end up with
429 just the directories needed to hold the resulting files.
431 - If the --itemize-changes (-i) option is repeated, rsync now includes
432 unchanged files in the itemized output (similar to -vv, but without all
433 the other verbose messages that can get in the way). Of course, the
434 client must be version 2.6.7 for this to work, but the remote rsync only
435 needs to be 2.6.7 if you're pushing files.
437 - Added the --specials option to tell rsync to copy non-device special
438 files (which rsync now attempts even as a normal user). The --devices
439 option now requests the copying of just devices (character and block).
440 The -D option still requests both (e.g. --devices and --specials), -a
441 still implies -D, and non-root users still get a silent downgrade that
442 omits device copying.
444 - Added the --super option to make the receiver always attempt super-user
445 activities. This is useful for systems that allow things such as devices
446 to be created or ownership to be set without being UID 0, and is also
447 useful for someone who wants to ensure that errors will be output if the
448 receiving rsync isn't being run as root.
450 - Added the --sockopts option for those few who want to customize the TCP
451 options used to contact a daemon rsync.
453 - Added a way for the --temp-dir option to be combined with a partial-dir
454 setting that lets rsync avoid non-atomic updates (for those times when
455 --temp-dir is not being used because space is tight).
457 - A new support script, files-to-excludes, will transform a list of files
458 into a set of include/exclude directives that will copy those files.
460 - A new option, --executability (-E) can be used to preserve just the
461 execute bit on files, for those times when using the --perms option is
464 - The daemon now logs each connection and also each module-list request
467 - New log-format options: %M (modtime), %U (uid), %G (gid), and %B
468 (permission bits, e.g. "rwxr-xrwt").
470 - The --dry-run option no longer forces the enabling of --verbose.
472 - The --remove-sent-files option now does a better job of incrementally
473 removing the sent files on the sending side (older versions tended to
474 clump up all the removals at the end).
476 - A daemon now supersedes its minimal SIGCHLD handler with the standard
477 PID-remembering version after forking. This ensures that the generator
478 can get the child-exit status from the receiver.
480 - Use of the --bwlimit option no longer interferes with the remote rsync
481 sending error messages about invalid/refused options.
483 - Rsync no longer returns a usage error when used with one local source arg
484 and no destination: this now implies the --list-only option, just like
485 the comparable situation with a remote source arg.
487 - Added the --copy-dirlinks option, a more limited version of --copy-links.
489 - Various documentation improvements, including: a better synopsis, some
490 improved examples, a better discussion of the presence and absence of
491 --perms (including how it interacts with the new --executability and
492 --chmod options), an extended discussion of --temp-dir, an improved
493 discussion of --partial-dir, a better description of rsync's pattern
494 matching characters, an improved --no-implied-dirs section, and the
495 documenting of what the --stats option outputs.
497 - Various new and updated diffs in the patches dir, including: acls.diff,
498 xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
502 - We now use sigaction() and sigprocmask() if possible, and fall back on
503 signal() if not. Using sigprocmask() ensures that rsync enables all the
504 signals that it needs, just in case it was started in a masked state.
506 - Some buffer sizes were expanded a bit, particularly on systems where
507 MAXPATHLEN is overly small (e.g. cygwin).
509 - If io_printf() tries to format more data than fits in the buffer, exit
510 with an error instead of transmitting a truncated buffer.
512 - If a va_copy macro is defined, lib/snprintf.c will use it when defining
515 - Reduced the amount of stack memory needed for each level of directory
516 recursion by nearly MAXPATHLEN bytes.
518 - The wildmatch function was extended to allow an array of strings to be
519 supplied as the string to match. This allows the exclude code to do less
522 - Got rid of the safe_fname() function (and all the myriad calls) and
523 replaced it with a new function in the log.c code that filters all the
524 output going to the terminal.
526 - Unified the f_name() and the f_name_to() functions.
528 - Improved the hash-table code the sender uses to handle checksums to make
529 it use slightly less memory and run just a little faster.
533 - The diffs in the patches dir now require "patch -p1 <DIFF" instead of
534 the previous -p0. Also, the version included in the release tar now
535 affect generated files (e.g. configure, rsync.1, proto.h, etc.), so
536 it is no longer necessary to run autoconf and/or yodl unless you're
537 applying a patch that was checked out from CVS.
539 - Several diffs in the patches dir now use the proper --enable-FOO
540 configure option instead of --with-FOO to turn on the inclusion of
541 the newly patched feature.
543 - There is a new script, "prepare-source" than can be used to update the
544 various generated files (proto.h, configure, etc.) even before configure
545 has created the Makefile (this is mainly useful when patching the source
546 with a patch that doesn't affect generated files).
548 - The testsuite now sets HOME so that it won't be affected by a file such
552 NEWS for rsync 2.6.6 (28 Jul 2005)
553 Protocol: 29 (unchanged)
558 - The zlib code was upgraded to version 1.2.3 in order to make it more
559 secure. While the widely-publicized security problem in zlib 1.2.2 did
560 not affect rsync, another security problem surfaced that affects rsync's
565 - The setting of flist->high in clean_flist() was wrong for an empty list.
566 This could cause flist_find() to crash in certain rare circumstances
567 (e.g. if just the right directory setup was around when --fuzzy was
568 combined with --link-dest).
570 - The outputting of hard-linked files when verbosity was > 1 was not right:
571 (1) Without -i it would output the name of each hard-linked file as
572 though it had been changed; it now outputs a "is hard linked" message for
573 the file. (2) With -i it would output all dots for the unchanged
574 attributes of a hard-link; it now changes those dots to spaces, as is
575 done for other totally unchanged items.
577 - When backing up a changed symlink or device, get rid of any old backup
578 item so that we don't get an "already exists" error.
580 - A couple places that were comparing a local and a remote modification-
581 time were not honoring the --modify-window option.
583 - Fixed a bug where the 'p' (permissions) itemized-changes flag might get
584 set too often (if some non-significant mode bits differed).
586 - Fixed a really old, minor bug that could cause rsync to warn about being
587 unable to mkdir() a path that ends in "/." because it just created the
588 directory (required --relative, --no-implied-dirs, a source path that
589 ended in either a trailing slash or a trailing "/.", and a non-existing
590 destination dir to tickle the bug in a recent version).
594 - Made the "max verbosity" setting in the rsyncd.conf file settable on a
595 per-module basis (which now matches the documentation).
597 - The support/rrsync script has been upgraded to verify the args of options
598 that take args (instead of rejecting any such options). The script was
599 also changed to try to be more secure and to fix a problem in the parsing
600 of a pull operation that has multiple sources.
602 - Improved the documentation that explains the difference between a
603 normal daemon transfer and a daemon-over remote-shell transfer.
605 - Some of the diffs supplied in the patches dir were fixed and/or
610 - Made configure define NOBODY_USER (currently hard-wired to "nobody") and
611 NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
612 find in the /etc/group file).
614 - Added a test to the test suite, itemized.test, that tests the output of
615 -i (log-format w/%i) and some double-verbose messages.
618 NEWS for rsync 2.6.5 (1 Jun 2005)
619 Protocol: 29 (unchanged)
624 - Non-printable chars in filenames are now output using backslash-
625 escaped characters rather than '?'s. Any non-printable character is
626 output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
627 is now output as "\\". Rsync also uses your locale setting, which
628 can make it treat fewer high-bit characters as non-printable.
630 - If rsync received an empty file-list when pulling files, it would
631 output a "nothing to do" message and exit with a 0 (success) exit
632 status, even if the remote rsync returned an error (it did not do
633 this under the same conditions when pushing files). This was changed
634 to make the pulling behavior the same as the pushing behavior: we
635 now do the normal end-of-run outputting (depending on options) and
636 exit with the appropriate exit status.
640 - A crash bug was fixed when a daemon had its "path" set to "/", did
641 not have chroot enabled, and used some anchored excludes in the
644 - Fixed a bug in the transfer of a single file when -H is specified
645 (rsync would either infinite loop or perhaps crash).
647 - Fixed a case where the generator might try (and fail) to tweak the
648 write-permissions of a read-only directory in list-only mode (this
649 only caused an annoying warning message).
651 - If --compare-dest or --link-dest uses a locally-copied file as the
652 basis for an updated version, log this better when --verbose or -i
655 - Fixed the accidental disabling of --backup during the --delete-after
658 - Restored the ability to use the --address option in client mode (in
659 addition to its use in daemon mode).
661 - Make sure that some temporary progress information from the delete
662 processing does not get left on the screen when it is followed by a
665 - When --existing skips a directory with extra verbosity, refer to it
666 as a "directory", not a "file".
668 - When transferring a single file to a different-named file, any
669 generator messages that are source-file related no longer refer to
670 the file by the destination filename.
672 - Fixed a bug where hard-linking a group of files might fail if the
673 generator hasn't created a needed destination directory yet.
675 - Fixed a bug where a hard-linked group of files that is newly-linked
676 to a file in a --link-dest dir doesn't link the files from the rest
679 - When deleting files with the --one-file-system (-x) option set, rsync
680 no longer tries to remove files from inside a mount-point on the
681 receiving side. Also, we don't complain about being unable to remove
684 - Fixed a compatibility problem when using --cvs-ignore (-C) and
685 sending files to an older rsync without using --delete.
687 - Make sure that a "- !" or "+ !" include/exclude pattern does not
688 trigger the list-clearing action that is reserved for "!".
690 - Avoid a timeout in the generator when the sender/receiver aren't
691 handling the generator's checksum output quickly enough.
693 - Fixed the omission of some directories in the delete processing when
694 --relative (-R) was combined with a source path that had a trailing
697 - Fixed a case where rsync would erroneously delete some files and then
698 re-transfer them when the options --relative (-R) and --recursive
699 (-r) were both enabled (along with --delete) and a source path had a
702 - Make sure that --max-size doesn't affect a device or a symlink.
704 - Make sure that a system with a really small MAXPATHLEN does not cause
705 the buffers in readfd_unbuffered() to be too small to receive normal
706 messages. (This mainly affected Cygwin.)
708 - If a source pathname ends with a filename of "..", treat it as if
709 "../" had been specified (so that we don't copy files to the parent
710 dir of the destination).
712 - If --delete is combined with a file-listing rsync command (i.e. no
713 transfer is happening), avoid outputting a warning that we couldn't
716 - If --stats is specified with --delete-after, ensure that all the
717 "deleting" messages are output before the statistics.
719 - Improved one "if" in the deletion code that was only checking errno
720 for ENOTEMPTY when it should have also been checking for EEXIST (for
721 compatibility with OS variations).
725 - Added the --only-write-batch=FILE option that may be used (instead
726 of --write-batch=FILE) to create a batch file without doing any
727 actual updating of the destination. This allows you to divert all
728 the file-updating data away from a slow data link (as long as you
729 are pushing the data to the remote server when creating the batch).
731 - When the generator is taking a long time to fill up its output buffer
732 (e.g. if the transferred files are few, small, or missing), it now
733 periodically flushes the output buffer so that the sender/receiver
734 can get started on the files sooner rather than later.
736 - Improved the keep-alive code to handle a long silence between the
737 sender and the receiver that can occur when the sender is receiving
738 the checksum data for a large file.
740 - Improved the auth-errors that are logged by the daemon to include
741 some information on why the authorization failed: wrong user,
742 password mismatch, etc. (The client-visible message is unchanged!)
744 - Improved the client's handling of an "@ERROR" from a daemon so that
745 it does not complain about an unexpectedly closed socket (since we
746 really did expect the socket to close).
748 - If the daemon can't open the log-file specified in rsyncd.conf, fall
749 back to using syslog and log an appropriate warning. This is better
750 than what was typically a totally silent (and fatal) failure (since a
751 daemon is not usually run with the --no-detach option that was
752 necessary to see the error on stderr).
754 - The man pages now consistently refer to an rsync daemon as a "daemon"
755 instead of a "server" (to distinguish it from the server process in a
756 non-daemon transfer).
758 - Made a small change to the rrsync script (restricted rsync -- in the
759 support dir) to make a read-only server reject all --remove-* options
760 when sending files (to future-proof it against the possibility of
761 other similar options being added at some point).
765 - Rsync now calls setlocale(LC_CTYPE, ""). This enables isprint() to
766 better discern which filename characters need to be escaped in
767 messages (which should result in fewer escaped characters in some
770 - Improved the naming of the log-file open/reopen/close functions.
772 - Removed some protocol-compatibility code that was only needed to help
773 someone running a pre-release of 2.6.4.
777 - Added configure option "--disable-locale" to disable any use of
778 setlocale() in the binary.
780 - Fixed a bug in the SUPPORT{,_HARD}_LINKS #defines which prevented
781 rsync from being built without symlink or hard-link support.
783 - Only #define HAVE_REMSH if it is going to be set to 1.
785 - Configure now disables the use of mkstemp() under HP-UX (since they
786 refuse to fix its broken handling of large files).
788 - Configure now explicitly checks for the lseek64() function so that
789 the code can use HAVE_LSEEK64 instead of inferring lseek64()'s
790 presence based on the presence of the off64_t type.
792 - Configure no longer mentions the change in the default remote-shell
793 (from rsh to ssh) that occurred for the 2.6.0 release.
795 - Some minor enhancements to the test scripts.
797 - Added a few new *.diff files to the patches dir, including a patch
798 that enables the optional copying of extended attributes.
801 NEWS for rsync 2.6.4 (30 March 2005)
802 Protocol: 29 (changed)
807 - When rsync deletes a directory and outputs a verbose message about
808 it, it now appends a trailing slash to the name instead of (only
809 sometimes) outputting a preceding "directory " string.
811 - The --stats output will contain file-list time-statistics if both
812 sides are 2.6.4, or if the local side is 2.6.4 and the files are
813 being pushed (since the stats come from the sending side).
814 (Requires protocol 29 for a pull.)
816 - The "%o" (operation) log-format escape now has a third value (besides
817 "send" and "recv"): "del." (with trailing dot to make it 4 chars).
818 This changes the way deletions are logged in the daemon's log file.
820 - When the --log-format option is combined with --verbose, rsync now
821 avoids outputting the name of the file twice in most circumstances.
822 As long as the --log-format item does not refer to any post-transfer
823 items (such as %b or %c), the --log-format message is output prior to
824 the transfer, so --verbose is now the equivalent of a --log-format of
825 '%n%L' (which outputs the name and any link info). If the log output
826 must occur after the transfer to be complete, the only time the name
827 is also output prior to the transfer is when --progress was specified
828 (so that the name will precede the progress stats, and the full
829 --log-format output will come after).
831 - Non-printable characters in filenames are replaced with a '?' to
832 avoid corrupting the screen or generating empty lines in the output.
836 - Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
837 was only treating it as a special token in an rsync include/exclude
840 - The combination of --verbose and --dry-run now mentions the full list
841 of changes that would be output without --dry-run.
843 - Avoid a mkdir warning when removing a directory in the destination
844 that already exists in the --backup-dir.
846 - An OS that has a binary mode for its files (such as cygwin) needed
847 setmode(fd, O_BINARY) called on the temp-file we opened with
848 mkstemp(). (Fix derived from cygwin's 2.6.3 rsync package.)
850 - Fixed a potential hang when verbosity is high, the client side is
851 the sender, and the file-list is large.
853 - Fixed a potential protocol-corrupting bug where the generator could
854 merge a message from the receiver into the middle of a multiplexed
855 packet of data if only part of that data had been written out to the
856 socket when the message from the generator arrived.
858 - We now check if the OS doesn't support using mknod() for creating
859 FIFOs and sockets, and compile-in some compatibility code using
860 mkfifo() and socket() when necessary.
862 - Fixed an off-by-one error in the handling of --max-delete=N. Also,
863 if the --max-delete limit is exceeded during a run, we now output a
864 warning about this at the end of the run and exit with a new error
867 - One place in the code wasn't checking if fork() failed.
869 - The "ignore nonreadable" daemon parameter used to erroneously affect
870 readable symlinks that pointed to a non-existent file.
872 - If the OS does not have lchown() and a chown() of a symlink will
873 affect the referent of a symlink (as it should), we no longer try
874 to set the user and group of a symlink.
876 - The generator now properly runs the hard-link loop and the dir-time
877 rewriting loop after we're sure that the redo phase is complete.
879 - When --backup was specified with --partial-dir=DIR, where DIR is a
880 relative path, the backup code was erroneously trying to backup a
881 file that was put into the partial-dir.
883 - If a file gets resent in a single transfer and the --backup option is
884 enabled along with --inplace, rsync no longer performs a duplicate
885 backup (it used to overwrite the first backup with the failed file).
887 - One call to flush_write_file() was not being checked for an error.
889 - The --no-relative option was not being sent from the client to a
892 - If an rsync daemon specified "dont compress = ..." for a file and the
893 client tried to specify --compress, the libz code was not handling a
894 compression level of 0 properly. This could cause a transfer failure
895 if the block-size for a file was large enough (e.g. rsync might have
896 exited with an error for large files).
898 - Fixed a bug that would sometimes surface when using --compress and
899 sending a file with a block-size larger than 64K (either manually
900 specified, or computed due to the file being really large). Prior
901 versions of rsync would sometimes fail to decompress the data
902 properly, and thus the transferred file would fail its verification.
904 - If a daemon can't open the specified log file (i.e. syslog is not
905 being used), die without crashing. We also output an error about
906 the failure on stderr (which will only be seen if --no-detach was
907 specified) and exit with a new error code (6).
909 - A local transfer no longer duplicates all its include/exclude options
910 (since the forked process already has a copy of the exclude list,
911 there's no need to send them a set of duplicates).
913 - The output of the items that are being updated by the generator (dirs,
914 symlinks, devices) is now intermingled in the proper order with the
915 output from the items that the receiver is updating (regular files)
916 when pulling. This misordering was particularly bad when --progress
917 was specified. (Requires protocol 29.)
919 - When --timeout is specified, lulls that occur in the transfer while
920 the generator is doing work that does not generate socket traffic
921 (looking for changed files, deleting files, doing directory-time
922 touch-ups, etc.) will cause a new keep-alive packet to be sent that
923 should keep the transfer going as long as the generator continues to
924 make progress. (Requires protocol 29.)
926 - The stat size of a device is not added to the total file size of the
927 items in the transfer (the size might be undefined on some OSes).
929 - Fixed a problem with refused-option messages sometimes not making it
930 back to the client side when a remote --files-from was in effect and
931 the daemon was the receiver.
933 - The --compare-dest option was not updating a file that differed in
934 (the preserved) attributes from the version in the compare-dest DIR.
936 - When rsync is copying files into a write-protected directory, fixed
937 the change-report output for the directory so that we don't report
938 an identical directory as changed.
942 - Rsync now supports popt's option aliases, which means that you can
943 use /etc/popt and/or ~/.popt to create your own option aliases.
945 - Added the --delete-during (--del) option which will delete files
946 from the receiving side incrementally as each directory in the
947 transfer is being processed. This makes it more efficient than the
948 default, before-the-transfer behavior, which is now also available as
949 --delete-before (and is still the default --delete-WHEN option that
950 will be chosen if --delete or --delete-excluded is specified without
951 a --delete-WHEN choice). All the --del* options infer --delete, so
952 an rsync daemon that refuses "delete" will still refuse to allow any
953 file-deleting options (including the new --remove-sent-files option).
955 - All the --delete-WHEN options are now more memory efficient:
956 Previously an duplicate set of file-list objects was created on the
957 receiving side for the entire destination hierarchy. The new
958 algorithm only creates one directory of objects at a time (for files
959 inside the transfer).
961 - Added the --copy-dest option, which works like --link-dest except
962 that it locally copies identical files instead of hard-linking them.
964 - Added support for specifying multiple --compare-dest, --copy-dest, or
965 --link-dest options, but only of a single type. (Promoted from the
966 patches dir and enhanced.) (Requires protocol 29.)
968 - Added the --max-size option. (Promoted from the patches dir.)
970 - The daemon-mode options are now separated from the normal rsync
971 options so that they can't be mixed together. This makes it
972 impossible to start a daemon that has improper default option values
973 (which could cause problems when a client connects, such as hanging
976 - The --bwlimit option may now be used in combination with --daemon
977 to specify both a default value for the daemon side and a value
978 that cannot be exceeded by a user-specified --bwlimit option.
980 - Added the "port" parameter to the rsyncd.conf file. (Promoted from
981 the patches dir.) Also added "address". The command-line options
982 take precedence over a config-file option, as expected.
984 - In _exit_cleanup(): when we are exiting with a partially-received
985 file, we now flush any data in the write-cache before closing the
988 - The --inplace support was enhanced to work with --compare-dest,
989 --link-dest, and (the new) --copy-dest options. (Requires protocol
992 - Added the --dirs (-d) option for an easier way to copy directories
993 without recursion. Any directories that are encountered are created
994 on the destination. Specifying a directory with a trailing slash
995 copies its immediate contents to the destination.
997 - The --files-from option now implies --dirs (-d).
999 - Added the --list-only option, which is mainly a way for the client to
1000 put the server into listing mode without needing to resort to any
1001 internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
1002 for a non-recursive listing). This option is used automatically
1003 (behind the scenes) when a modern rsync speaks to a modern daemon,
1004 but may also be specified manually if you want to force the use of
1005 the --list-only option over a remote-shell connection.
1007 - Added the --omit-dir-times (-O) option, which will avoid updating
1008 the modified time for directories when --times was specified. This
1009 option will avoid an extra pass through the file-list at the end of
1010 the transfer (to tweak all the directory times), which may provide
1011 an appreciable speedup for a really large transfer. (Promoted from
1014 - Added the --filter (-f) option and its helper option, -F. Filter
1015 rules are an extension to the existing include/exclude handling
1016 that also supports nested filter files as well as per-directory
1017 filter files (like .cvsignore, but with full filter-rule parsing).
1018 This new option was chosen in order to ensure that all existing
1019 include/exclude processing remained 100% compatible with older
1020 versions. Protocol 29 is needed for full filter-rule support, but
1021 backward-compatible rules work with earlier protocol versions.
1022 (Promoted from the patches dir and enhanced.)
1024 - Added the --delay-updates option that puts all updated files into
1025 a temporary directory (by default ".~tmp~", but settable via the
1026 --partial-dir=DIR option) until the end of the transfer. This
1027 makes the updates a little more atomic for a large transfer.
1029 - If rsync is put into the background, any output from --progress is
1032 - Documented the "max verbosity" setting for rsyncd.conf. (This
1033 setting was added a couple releases ago, but left undocumented.)
1035 - The sender and the generator now double-check the file-list index
1036 they are given, and refuse to try to do a file transfer on a
1037 non-file index (since that would indicate that something had gone
1040 - Added the --itemize-changes (-i) option, which is a way to output a
1041 more detailed list of what files changed and in what way. The effect
1042 is the same as specifying a --log-format of "%i %n%L" (see both the
1043 rsync and rsyncd.conf manpages). Works with --dry-run too.
1045 - Added the --fuzzy (-y) option, which attempts to find a basis file
1046 for a file that is being created from scratch. The current algorithm
1047 only looks in the destination directory for the created file, but it
1048 does attempt to find a match based on size/mod-time (in case the file
1049 was renamed with no other changes) as well as based on a fuzzy
1050 name-matching algorithm. This option requires protocol 29 because it
1051 needs the new file-sorting order. (Promoted from patches dir and
1052 enhanced.) (Requires protocol 29.)
1054 - Added the --remove-sent-files option, which lets you move files
1057 - The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
1058 enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
1059 literals in the rsync://HOST:PORT/PATH format.)
1061 - When rsync recurses to build the file list, it no longer keeps open
1062 one or more directory handles from the dir's parent dirs.
1064 - When building under windows, the default for --daemon is now to
1065 avoid detaching, requiring the new --detach option to force rsync
1068 - The --dry-run option can now be combined with either --write-batch or
1069 --read-batch, allowing you to run a do-nothing test command to see
1070 what would happen without --dry-run.
1072 - The daemon's "read only" config item now sets an internal read_only
1073 variable that makes extra sure that no write/delete calls on the
1074 read-only side can succeed.
1076 - The log-format % escapes can now have a numeric field width in
1077 between the % and the escape letter (e.g. "%-40n %08p").
1079 - Improved the option descriptions in the --help text.
1083 - Added atomic-rsync to the support dir: a perl script that will
1084 transfer some files using rsync, and then move the updated files into
1085 place all at once at the end of the transfer. Only works when
1086 pulling, and uses --link-dest and a parallel hierarchy of files to
1089 - Added mnt-excl to the support dir: a perl script that takes the
1090 /proc/mounts file and translates it into a set of excludes that will
1091 exclude all mount points (even mapped mounts to the same disk). The
1092 excludes are made relative to the specified source dir and properly
1095 - Added savetransfer.c to the support dir: a C program that can make
1096 a copy of all the data that flows over the wire. This lets you test
1097 for data corruption (by saving the data on both the sending side and
1098 the receiving side) and provides one way to debug a protocol error.
1100 - Added rrsync to the support dir: this is an updated version of Joe
1101 Smith's restricted rsync perl script. This helps to ensure that only
1102 certain rsync commands can be run by an ssh invocation.
1106 - Added better checking of the checksum-header values that come over
1109 - Merged a variety of file-deleting functions into a single function so
1110 that it is easier to maintain.
1112 - Improved the type of some variables (particularly blocksize vars) for
1113 consistency and proper size.
1115 - Got rid of the uint64 type (which we didn't need).
1117 - Use a slightly more compatible set of core #include directives.
1119 - Defined int32 in a way that ensures that the build dies if we can't
1120 find a variable with at least 32 bits.
1122 PROTOCOL DIFFERENCES FOR VERSION 29:
1124 - A 16-bit flag-word is transmitted after every file-list index. This
1125 indicates what is changing between the sender and the receiver. The
1126 generator now transmits an index and a flag-word to indicate when
1127 dirs and symlinks have changed (instead of producing a message),
1128 which makes the outputting of the information more consistent and
1129 less prone to screen corruption (because the local receiver/sender is
1130 now outputting all the file-change info messages).
1132 - If a file is being hard-linked, the ITEM_XNAME_FOLLOWS bit is enabled
1133 in the flag-word and the name of the file that was linked immediately
1134 follows in vstring format (see below).
1136 - If a file is being transferred with an alternate-basis file, the
1137 ITEM_BASIS_TYPE_FOLLOWS bit is enabled in the flag-word and a single
1138 byte follows, indicating what type of basis file was chosen. If that
1139 indicates that a fuzzy-match was selected, the ITEM_XNAME_FOLLOWS bit
1140 is set in the flag-word and the name of the match in vstring format
1141 follows the basis byte. A vstring is a variable length string that
1142 has its size written prior to the string, and no terminating null.
1143 If the string is from 1-127 bytes, the length is a single byte. If
1144 it is from 128-32767 bytes, the length is written as ((len >> 8) |
1145 0x80) followed by (len % 0x100).
1147 - The sending of exclude names is done using filter-rule syntax. This
1148 means that all names have a prefixed rule indicator, even excludes
1149 (which used to be sent as a bare pattern, when possible). The -C
1150 option will include the per-dir .cvsignore merge file in the list of
1151 filter rules so it is positioned correctly (unlike in some older
1152 transfer scenarios).
1154 - Rsync sorts the filename list in a different way: it sorts the subdir
1155 names after the non-subdir names for each dir's contents, and it
1156 always puts a dir's contents immediately after the dir's name in the
1157 list. (Previously an item named "foo.txt" would sort in between
1158 directory "foo/" and "foo/bar".)
1160 - When talking to a protocol 29 rsync daemon, a list-only request
1161 is able to note this before the options are sent over the wire and
1162 the new --list-only option is included in the options.
1164 - When the --stats bytes are sent over the wire (or stored in a batch),
1165 they now include two elapsed-time values: one for how long it took to
1166 build the file-list, and one for how long it took to send it over the
1167 wire (each expressed in thousandths of a second).
1169 - When --delete-excluded is specified with some filter rules (AKA
1170 excludes), a client sender will now initiate a send of the rules to
1171 the receiver (older protocols used to omit the sending of excludes in
1172 this situation since there were no receiver-specific rules that
1173 survived --delete-excluded back then). Note that, as with all the
1174 filter-list sending, only items that are significant to the other
1175 side will actually be sent over the wire, so the filter-rule list
1176 that is sent in this scenario is often empty.
1178 - An index equal to the file-list count is sent as a keep-alive packet
1179 from the generator to the sender, which then forwards it on to the
1180 receiver. This normally invalid index is only a valid keep-alive
1181 packet if the 16-bit flag-word that follows it contains a single bit
1182 (ITEM_IS_NEW, which is normally an illegal flag to appear alone).
1184 - A protocol-29 batch file includes a bit for the setting of the --dirs
1185 option and for the setting of the --compress option. Also, the shell
1186 script created by --write-batch will use the --filter option instead
1187 of --exclude-from to capture any filter rules.
1191 - Handle an operating system that use mkdev() in place of makedev().
1193 - Improved configure to better handle cross-compiling.
1196 NEWS for rsync 2.6.3 (30 Sep 2004)
1197 Protocol: 28 (unchanged)
1198 Changes since 2.6.2:
1202 - A bug in the sanitize_path routine (which affects a non-chrooted
1203 rsync daemon) could allow a user to craft a pathname that would get
1204 transformed into an absolute path for certain options (but not for
1205 file-transfer names). If you're running an rsync daemon with chroot
1206 disabled, *please upgrade*, ESPECIALLY if the user privs you run
1207 rsync under is anything above "nobody".
1209 OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
1211 - Please note that the 2-line footer (output when verbose) now uses the
1212 term "sent" instead of "wrote" and "received" instead of "read". If
1213 you are not parsing the numeric values out of this footer, a script
1214 would be better off using the empty line prior to the footer as the
1215 indicator that the verbose output is over.
1217 - The output from the --stats option was similarly affected to change
1218 "written" to "sent" and "read" to "received".
1220 - Rsync ensures that a filename that contains a newline gets mentioned
1221 with each newline transformed into a question mark (which prevents a
1222 filename from causing an empty line to be output).
1224 - The "backed up ..." message that is output when at least 2 --verbose
1225 options are specified is now the same both with and without the
1226 --backup-dir option.
1230 - Fixed a crash bug that might appear when --delete was used and
1231 multiple source directories were specified.
1233 - Fixed a 32-bit truncation of the file length when generating the
1236 - The --backup code no longer attempts to create some directories
1237 over and over again (generating warnings along the way).
1239 - Fixed a bug in the reading of the secrets file (by the daemon) and
1240 the password file (by the client): the files no longer need to be
1241 terminated by a newline for their content to be read in.
1243 - If a file has a read error on the sending side or the reconstructed
1244 data doesn't match the expected checksum (perhaps due to the basis
1245 file changing during the transfer), the receiver will no longer
1246 retain the resulting file unless the --partial option was specified.
1247 (Note: for the read-error detection to work, neither side can be
1248 older than 2.6.3 -- older receivers will always retain the file, and
1249 older senders don't tell the receiver that the file had a read
1252 - If a file gets resent in a single transfer and the --backup option
1253 is enabled, rsync no longer performs a duplicate backup (it used to
1254 overwrite the original file in the backup area).
1256 - Files specified in the daemon's "exclude" or "exclude from" config
1257 items are now excluded from being uploaded (assuming that the module
1258 allows uploading at all) in addition to the old download exclusion.
1260 - Got rid of a potential hang in the receiver when near the end of a
1263 - When using --backup without a --backup-dir, rsync no longer preserves
1264 the modify time on directories. This avoids confusing NFS.
1266 - When --copy-links (-L) is specified, we now output a separate error
1267 for a symlink that has no referent instead of claiming that a file
1270 - The --copy-links (-L) option no longer has the side-effect of telling
1271 the receiving side to follow symlinks. See the --keep-dirlinks
1272 option (mentioned below) for a way to specify that behavior.
1274 - Error messages from the daemon server's option-parsing (such as
1275 refused options) are now successfully transferred back to the client
1276 (the server used to fail to send the message because the socket
1277 wasn't in the right state for the message to get through).
1279 - Most transfer errors that occur during a daemon transfer are now
1280 returned to the user in addition to being logged (some messages are
1281 intended to be daemon-only and are not affected by this).
1283 - Fixed a bug in the daemon authentication code when using one of the
1284 batch-processing options.
1286 - We try to work around some buggy IPv6 implementations that fail to
1287 implement IPV6_V6ONLY. This should fix the "address in use" error
1288 that some daemons get when running on an OS with a buggy IPv6
1289 implementation. Also, if the new code gets this error, we might
1290 suggest that the user specify --ipv4 or --ipv6 (if we think it will
1293 - When the remote rsync dies, make a better effort to recover any error
1294 messages it may have sent before dying (the local rsync used to just
1295 die with a socket-write error).
1297 - When using --delete and a --backup-dir that contains files that are
1298 hard-linked to their destination equivalents, rsync now makes sure
1299 that removed files really get removed (avoids a really weird rename()
1302 - Avoid a bogus run-time complaint about a lack of 64-bit integers when
1303 the int64 type is defined as an off_t and it actually has 64-bits.
1305 - Added a configure check for open64() without mkstemp64() so that we
1306 can avoid using mkstemp() when such a combination is encountered.
1307 This bypasses a problem writing out large temp files on OSes such as
1310 - Fixed an age-old crash problem with --read-batch on a local copy
1311 (rsync was improperly assuming --whole-file for the local copy).
1313 - When --dry-run (-n) is used and the destination directory does not
1314 exist, rsync now produces a correct report of files that would be
1315 sent instead of dying with a chdir() error.
1317 - Fixed a bug that could cause a slow-to-connect rsync daemon to die
1318 with an error instead of waiting for the connection to finish.
1320 - Fixed an ssh interaction that could cause output to be lost when the
1321 user chose to combine the output of rsync's stdout and stderr (e.g.
1324 - Fixed an option-parsing bug when --files-from got passed to a daemon.
1328 - Added the --partial-dir=DIR option that lets you specify where to
1329 (temporarily) put a partially transferred file (instead of over-
1330 writing the destination file). E.g. --partial-dir=.rsync-partial
1331 Also added support for the RSYNC_PARTIAL_DIR environment variable
1332 that, when found, transforms a regular --partial option (such as
1333 the convenient -P option) into one that also specifies a directory.
1335 - Added --keep-dirlinks (-K), which allows you to symlink a directory
1336 onto another partition on the receiving side and have rsync treat it
1337 as matching a normal directory from the sender.
1339 - Added the --inplace option that tells rsync to write each destination
1340 file without using a temporary file. The matching of existing data
1341 in the destination file can be severely limited by this, but there
1342 are also cases where this is more efficient (such as appending data).
1343 Use only when needed (see the man page for more details).
1345 - Added the "write only" option for the daemon's config file.
1347 - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
1348 and documented all these options in the man page.
1350 - Improved the handling of the --bwlimit option so that it's less
1351 bursty, more accurate, and works properly over a larger range of
1354 - The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
1355 SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
1357 - Added the --checksum-seed=N option for advanced users.
1359 - Batch writing/reading has a brand-new implementation that is simpler,
1360 fixes a few weird problems with the old code (such as no longer
1361 sprinkling the batch files into different dirs or even onto different
1362 systems), and is much less intrusive into the code (making it easier
1363 to maintain for the future). The new code generates just one data
1364 file instead of three, which makes it possible to read the batch on
1365 stdin via a remote shell. Also, the old requirement of forcing the
1366 same fixed checksum-seed for all batch processing has been removed.
1368 - If an rsync daemon has a module set with "list = no" (which hides its
1369 presence in the list of available modules), a user that fails to
1370 authenticate gets the same "unknown module" error that they would get
1371 if the module were actually unknown (while still logging the real
1372 error to the daemon's log file). This prevents fishing for module
1375 - The daemon's "refuse options" config item now allows you to match
1376 option names using wildcards and/or the single-letter option names.
1378 - Each transferred file now gets its permissions and modified-time
1379 updated before the temp-file gets moved into place. Previously, the
1380 finished file would have a very brief window where its permissions
1381 disallowed all group and world access.
1383 - Added the ability to parse a literal IPv6 address in an "rsync:" URL
1384 (e.g. rsync://[2001:638:500:101::21]:873/module/dir).
1386 - The daemon's wildcard expanding code can now handle more than 1000
1387 filenames (it's now limited by memory instead of having a hard-wired
1392 - Some cleanup in the exclude code has saved some per-exclude memory
1393 and made the code easier to maintain.
1395 - Improved the argv-overflow checking for a remote command that has a
1398 - Use rsyserr() in the various places that were still calling rprintf()
1399 with strerror() as an arg.
1401 - If an rsync daemon is listening on multiple sockets (to handle both
1402 IPv4 and IPv6 to a single port), we now close all the unneeded file
1403 handles after we accept a connection (we used to close just one of
1406 - Optimized the handling of larger block sizes (rsync used to slow to a
1407 crawl if the block size got too large).
1409 - Optimized away a loop in hash_search().
1411 - Some improvements to the sanitize_path() and clean_fname() functions
1412 makes them more efficient and produce better results (while still
1413 being compatible with the file-name cleaning that gets done on both
1414 sides when sending the file-list).
1416 - Got rid of alloc_sanitize_path() after adding a destination-buffer
1417 arg to sanitize_path() made it possible to put all the former's
1418 functionality into the latter.
1420 - The file-list that is output when at least 4 verbose options are
1421 specified reports the uid value on the sender even when rsync is
1422 not running as root (since we might be sending to a root receiver).
1426 - Added a "gen" target to rebuild most of the generated files,
1427 including configure, config.h.in, the man pages, and proto.h.
1429 - If "make proto" doesn't find some changes in the prototypes, the
1430 proto.h file is left untouched (its time-stamp used to always be
1433 - The variable $STRIP (that is optionally set by the install-strip
1434 target's rule) was changed to $INSTALL_STRIP because some systems
1435 have $STRIP already set in the environment.
1437 - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
1439 - When cross-compiling, the gettimeofday() function is now assumed to
1440 be a modern version that takes two-args (since we can't test it).
1444 - The scripts in the testsuite dir were cleaned up a bit and a few
1447 - Some new diffs were added to the patches dir, and some accepted
1451 NEWS for rsync 2.6.2 (30 Apr 2004)
1452 Protocol: 28 (unchanged)
1453 Changes since 2.6.1:
1457 - Fixed a major bug in the sorting of the filenames when --relative
1458 is used for some sources (just sources such as "/" and "/*" were
1459 affected). This fix ensures that we ask for the right file-list
1460 item when requesting changes from the sender.
1462 - Rsync now checks the return value of the close() function to
1463 better report disk-full problems on an NFS file system.
1465 - Restored the old daemon-server behavior of logging error messages
1466 rather than returning them to the user. (A better long-term fix
1467 will be sought in the future.)
1469 - An obscure uninitialized-variable bug was fixed in the uid/gid
1470 code. (This bug probably had no ill effects.)
1474 - Got rid of the configure check for sys/sysctl.h (it wasn't used
1475 and was causing a problem on some systems). Also improved the
1476 broken-largefile-locking test to try to avoid failure due to an
1479 - Fixed a compile problem on systems that don't define
1482 - Fixed a compile problem in the popt source for compilers that
1483 don't support __attribute__.
1487 - Improved the testsuite's "merge" test to work on OSF1.
1489 - Two new diffs were added to the patches dir.
1492 NEWS for rsync 2.6.1 (26 Apr 2004)
1493 Protocol: 28 (changed)
1494 Changes since 2.6.0:
1498 - Paths sent to an rsync daemon are more thoroughly sanitized when
1499 chroot is not used. If you're running a non-read-only rsync
1500 daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
1501 user privs you run rsync under is anything above "nobody".
1505 - Lower memory use, more optimal transfer of data over the socket,
1506 and lower CPU usage (see the INTERNAL section for details).
1508 - The RSYNC_PROXY environment variable can now contain a
1509 "USER:PASS@" prefix before the "HOST:PORT" information.
1512 - The --progress output now mentions how far along in the transfer
1513 we are, including both a count of files transferred and a
1514 percentage of the total file-count that we've processed. It also
1515 shows better current-rate-of-transfer and remaining-transfer-time
1518 - Documentation changes now attempt to describe some often mis-
1519 understood features more clearly.
1523 - When -x (--one-file-system) is combined with -L (--copy-links) or
1524 --copy-unsafe-links, no symlinked files are skipped, even if the
1525 referent file is on a different filesystem.
1527 - The --link-dest code now works properly for a non-root user when
1528 (1) the UIDs of the source and destination differ and -o was
1529 specified, or (2) when the group of the source can't be used on
1530 the destination and -g was specified.
1532 - Fixed a bug in the handling of -H (hard-links) that might cause
1533 the expanded PATH/NAME value of the current item to get
1534 overwritten (due to an expanded-name caching bug).
1536 - We now reset the "new data has been sent" flag at the start of
1537 each file we send. This makes sure that an interrupted transfer
1538 with the --partial option set doesn't keep a shorter temp file
1539 than the current basis file when no new data has been transferred
1540 over the wire for that file.
1542 - Fixed a byte-order problem in --batch-mode on big-endian machines.
1545 - When using --cvs-exclude, the exclude items we get from a
1546 per-directory's .cvsignore file once again only affect that one
1547 directory (not all following directories too). The items are also
1548 now properly word-split and parsed without any +/- prefix parsing.
1550 - When specifying the USER@HOST: prefix for a file, the USER part
1551 can now contain an '@', if needed (i.e. the last '@' is used to
1552 find the HOST, not the first).
1554 - Fixed some bugs in the handling of group IDs for non-root users:
1555 (1) It properly handles a group that the sender didn't have a name
1556 for (it would previously skip changing the group on any files in
1557 that group). (2) If --numeric-ids is used, rsync no longer
1558 attempts to set groups that the user doesn't have the permission
1561 - Fixed the "refuse options" setting in the rsyncd.conf file.
1563 - Improved the -x (--one-file-system) flag's handling of any mount-
1564 point directories we encounter. It is both more optimal (in that
1565 it no longer does a useless scan of the contents of the mount-
1566 point dirs) and also fixes a bug where a remapped mount of the
1567 original filesystem could get discovered in a subdir we should be
1570 - Rsync no longer discards a double-slash at the start of a filename
1571 when trying to open the file. It also no longer constructs names
1572 that start with a double slash (unless the user supplied them).
1574 - Path-specifying options to a daemon should now work the same with
1575 or without chroot turned on. Previously, such a option (such as
1576 --link-dest) would get its absolute path munged into a relative
1577 one if chroot was not on, making that setting fairly useless.
1578 Rsync now transforms the path into one that is based on the
1579 module's base dir when chroot is not enabled.
1581 - Fixed a compatibility problem interacting with older rsync
1582 versions that might send us an empty --suffix value without
1583 telling us that --backup-dir was specified.
1585 - The "hosts allow" option for a daemon-over-remote-shell process
1586 now has improved support for IPv6 addresses and a fix for systems
1587 that have a length field in their socket structs.
1589 - Fixed the ability to request an empty backup --suffix when sending
1590 files to an rsync daemon.
1592 - Fixed an option-parsing bug when --files-from was sent to a server
1597 - Most of the I/O is now buffered, which results in a pretty large
1598 speedup when running under MS Windows. (Craig Barratt)
1600 - Optimizations to the name-handling/comparing code have made some
1601 significant reductions in user-CPU time for large file sets.
1603 - Some cleanup of the variable types make the code more consistent.
1605 - Reduced memory requirements of hard link preservation.
1608 - Implemented a new algorithm for hard-link handling that speeds up
1609 the code significantly. (J.W. Schultz and Wayne Davison)
1611 - The --hard-link option now uses the first existing file in the
1612 group of linked files as the basis for the transfer. This
1613 prevents the sub-optimal transfer of a file's data when a new
1614 hardlink is added on the sending side and it sorts alphabetically
1615 earlier in the list than the files that are already present on the
1618 - Dropped support for protocol versions less than 20 (2.3.0 released
1619 15 Mar 1999) and activated warnings for protocols less than 25
1620 (2.5.0 released 23 Aug 2001). (Wayne Davison and J.W. Schultz,
1623 - More optimal data transmission for --hard-links (protocol 28).
1625 - More optimal data transmission for --checksum (protocol 28).
1627 - Less memory is used when --checksum is specified.
1629 - Less memory is used in the file list (a per-file savings).
1631 - The generator is now better about not modifying the file list
1632 during the transfer in order to avoid a copy-on-write memory
1633 bifurcation (on systems where fork() uses shared memory).
1634 Previously, rsync's shared memory would slowly become unshared,
1635 resulting in real memory usage nearly doubling on the receiving
1636 side by the end of the transfer. Now, as long as permissions
1637 are being preserved, the shared memory should remain that way
1638 for the entire transfer.
1640 - Changed hardlink info and file_struct + strings to use allocation
1641 pools. This reduces memory use for large file-sets and permits
1642 freeing memory to the OS. (J.W. Schultz)
1644 - The 2 pipes used between the receiver and generator processes
1645 (which are forked on the same machine) were reduced to 1 pipe and
1646 the protocol improved so that (1) it is now impossible to have the
1647 "redo" pipe fill up and hang rsync, and (2) trailing messages from
1648 the receiver don't get lost on their way through the generator
1649 over to the sender (which mainly affected hard-link messages and
1650 verbose --stats output).
1652 - Improved the internal uid/gid code to be more portable and a
1653 little more optimized.
1655 - The device numbers sent when using --devices are now sent as
1656 separate major/minor values with 32-bit accuracy (protocol 28).
1657 Previously, the copied devices were sent as a single 32-bit
1658 number. This will make inter-operation of 64-bit binaries more
1659 compatible with their 32-bit brethren (with both ends of the
1660 connection are using protocol 28). Note that optimizations in the
1661 binary protocol for sending the device numbers often results in
1662 fewer bytes being used than before, even though more precision is
1665 - Some cleanup of the exclude/include structures and its code made
1666 things clearer (internally), simpler, and more efficient.
1668 - The reading & writing of the file-list in batch-mode is now
1669 handled by the same code that sends & receives the list over the
1670 wire. This makes it much easier to maintain. (Note that the
1671 batch code is still considered to be experimental.)
1675 - The configure script now accepts --with-rsyncd-conf=PATH to
1676 override the default value of the /etc/rsyncd.conf file.
1678 - Fixed configure bug when running "./configure --disable-ipv6".
1680 - Fixed compilation problem on Tru64 Unix (having to do with
1681 sockaddr.sa_len and sockaddr.sin_len).
1685 - Fixed "make test" bug when build dir is not the source dir.
1687 - Added a couple extra diffs in the "patches" dir, removed the ones
1688 that got applied, and rebuilt the rest.
1691 NEWS for rsync 2.6.0 (1 Jan 2004)
1692 Protocol: 27 (changed)
1693 Changes since 2.5.7:
1697 * "ssh" is now the default remote shell for rsync. If you want to
1698 change this, configure like this: "./configure --with-rsh=rsh".
1700 * Added --files-from, --no-relative, --no-implied-dirs, and --from0.
1701 Note that --from0 affects the line-ending character for all the
1702 files read by the --*-from options. (Wayne Davison)
1704 * Length of csum2 is now per-file starting with protocol version
1707 * Per-file dynamic block size is now sqrt(file length). The
1708 per-file checksum size is determined according to an algorithm
1709 provided by Donovan Baarda which reduces the probability of rsync
1710 algorithm corrupting data and falling back using the whole md4
1711 checksums. (J.W. Schultz, Donovan Baarda)
1713 * The --stats option no longer includes the (debug) malloc summary
1714 unless the verbose option was specified at least twice.
1716 * Added a new error/warning code for when files vanish from the
1717 sending side. Made vanished source files not interfere with the
1718 file-deletion pass when --delete-after was specified.
1720 * Various trailing-info sections are now preceded by a newline.
1724 * Fixed several exclude/include matching bugs when using wild-cards.
1725 This has a several user-visible effects, all of which make the
1726 matching more consistent and intuitive. This should hopefully not
1727 cause anyone problems since it makes the matching work more like
1728 what people are expecting. (Wayne Davison)
1730 - A pattern with a "**" no longer causes a "*" to match slashes.
1731 For example, with "/*/foo/**", "foo" must be 2 levels deep.
1732 [If your string has BOTH "*" and "**" wildcards, changing the
1733 "*" wildcards to "**" will provide the old behavior in all
1736 - "**/foo" now matches at the base of the transfer (like /foo
1737 does). [Use "/**/foo" to get the old behavior in all versions.]
1739 - A non-anchored wildcard term floats to match beyond the base of
1740 the transfer. E.g. "CVS/R*" matches at the end of the path,
1741 just like the non-wildcard term "CVS/Root" does. [Use "/CVS/R*"
1742 to get the old behavior in all versions.]
1744 - Including a "**" in the match term causes it to be matched
1745 against the entire path, not just the name portion, even if
1746 there aren't any interior slashes in the term. E.g. "foo**bar"
1747 would exclude "/path/foo-bar" (just like before) as well as
1748 "/foo-path/baz-bar" (unlike before). [Use "foo*bar" to get the
1749 old behavior in all versions.]
1751 * The exclude list specified in the daemon's config file is now
1752 properly applied to the pulled items no matter how deep the
1753 user's file-args are in the source tree. (Wayne Davison)
1755 * For protocol version >= 27, mdfour_tail() is called when the
1756 block size (including checksum_seed) is a multiple of 64.
1757 Previously it was not called, giving the wrong MD4 checksum.
1760 * For protocol version >= 27, a 64 bit bit counter is used in
1761 mdfour.c as required by the RFC. Previously only a 32 bit bit
1762 counter was used, causing incorrect MD4 file checksums for
1763 file sizes >= 512MB - 4. (Craig Barratt)
1765 * Fixed a crash bug when interacting with older rsync versions and
1766 multiple files of the same name are destined for the same dir.
1769 * Keep tmp names from overflowing MAXPATHLEN.
1771 * Make --link-dest honor the absence of -p, -o, and -g.
1773 * Made rsync treat a trailing slash in the destination in a more
1776 * Fixed file I/O error detection. (John Van Essen)
1778 * Fixed bogus "malformed address {hostname}" message in rsyncd log
1779 when checking IP address against hostnames from "hosts allow"
1780 and "hosts deny" parameters in config file.
1782 * Print heap statistics when verbose >= 2 instead of when >= 1.
1784 * Fixed a compression (-z) bug when syncing a mostly-matching file
1785 that contains already-compressed data. (Yasuoka Masahiko and
1788 * Fixed a bug in the --backup code that could cause deleted files
1789 to not get backed up.
1791 * When the backup code makes new directories, create them with mode
1792 0700 instead of 0755 (since the directory permissions in the
1793 backup tree are not yet copied from the main tree).
1795 * Call setgroups() in a more portable manner.
1797 * Improved file-related error messages to better indicate exactly
1798 what pathname failed. (Wayne Davison)
1800 * Fixed some bugs in the handling of --delete and --exclude when
1801 using the --relative (-R) option. (Wayne Davison)
1803 * Fixed bug that prevented regular files from replacing
1804 special files and caused a directory in --link-dest or
1805 --compare-dest to block the creation of a file with the
1806 same path. A directory still cannot be replaced by a
1807 regular file unless --delete specified. (J.W. Schultz)
1809 * Detect and report when open or opendir succeed but read and
1810 readdir fail caused by network filesystem issues and truncated
1811 files. (David Norwood, Michael Brown, J.W. Schultz)
1813 * Added a fix that should give ssh time to restore the tty settings
1814 if the user presses Ctrl-C at an ssh password prompt.
1818 * Eliminated vestigial support for old versions that we stopped
1819 supporting. (J.W. Schultz)
1821 * Simplified some of the option-parsing code. (Wayne Davison)
1823 * Some cleanup made to the exclude code, as well as some new
1824 defines added to enhance readability. (Wayne Davison)
1826 * Changed the protocol-version code so that it can interact at a
1827 lower protocol level than the maximum supported by both sides.
1828 Added an undocumented option, --protocol=N, to force the value
1829 we advertise to the other side (primarily for testing purposes).

1849 * The --delete-after option now implies --delete. (Wayne Davison)
1851 * The --suffix option can now be used with --backup-dir. (Michael
1854 * Combining "::" syntax with the --rsh/-e option now uses the
1855 specified remote-shell as a transport to talk to a (newly-spawned)
1856 server-daemon. This allows someone to use daemon features, such
1857 as modules, over a secure protocol, such as ssh. (JD Paul)
1859 * The rsync:// syntax for daemon connections is now accepted in the
1862 * If the file name given to --include-from or --exclude-from is "-",
1863 rsync will read from standard input. (J.W. Schultz)
1865 * New option --link-dest which is like --compare-dest except that
1866 unchanged files are hard-linked in to the destination directory.
1869 * Don't report an error if an excluded file disappears during an
1870 rsync run. (Eugene Chupriyanov and Bo Kersey)
1872 * Added .svn to --cvs-exclude list to support subversion. (Jon
1875 * Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
1876 and "hosts deny" fields. (Hideaki Yoshifuji)
1878 * Changed exclude file handling to permit DOS or MAC style line
1879 terminations. (J.W. Schultz)
1881 * Ignore errors from chmod when -p/-a/--preserve-perms is not set.
1886 * Fix "forward name lookup failed" errors on AIX 4.3.3. (John
1887 L. Allen, Martin Pool)
1889 * Generate each file's rolling-checksum data as we send it, not
1890 in a separate (memory-eating) pass before hand. This prevents
1891 timeout errors on really large files. (Stefan Nehlsen)
1893 * Fix compilation on Tru64. (Albert Chin, Zoong Pham)
1895 * Better handling of some client-server errors. (Martin Pool)
1897 * Fixed a crash that would occur when sending a list of files that
1898 contains a duplicate name (if it sorts to the end of the file
1899 list) and using --delete. (Wayne Davison)
1901 * Fixed the file-name duplicate-removal code when dealing with multiple
1902 dups in a row. (Wayne Davison)
1904 * Fixed a bug that caused rsync to lose the exit status of its child
1905 processes and sometimes return an exit code of 0 instead of showing
1906 an error. (David R. Staples, Dave Dykstra)
1908 * Fixed bug in --copy-unsafe-links that caused it to be completely
1909 broken. (Dave Dykstra)
1911 * Prevent infinite recursion in cleanup code under certain circumstances.
1912 (Sviatoslav Sviridov and Marc Espie)
1914 * Fixed a bug that prevented rsync from creating intervening directories
1915 when --relative-paths/-R is set. (Craig Barratt)
1917 * Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
1921 * Many code cleanups and improved internal documentation. (Martin
1924 * Portability fixes. (Dave Dykstra and Wayne Davison)
1926 * More test cases. (Martin Pool)
1928 * Some test-case fixes. (Brian Poole, Wayne Davison)
1930 * Updated included popt to the latest vendor drop, version 1.6.4.
1933 * Updated config.guess and config.sub to latest versions; this
1934 means rsync should build on more platforms. (Paul Green)

1943 * With --progress, when a transfer is complete show the time taken;
1944 otherwise show expected time to complete. (Cameron Simpson)
1946 * Make "make install-strip" works properly, and "make install"
1947 accepts a DESTDIR variable for help in building binary packages.
1948 (Peter Breitenlohner, Greg Louis)
1950 * If configured with --enable-maintainer-mode, then on receipt of
1951 a fatal signal rsync will try to open an xterm running gdb,
1952 similarly to Samba's "panic action" or GNOME's bug-buddy.
1958 * Fix situation where failure to fork (e.g. because out of process
1959 slots) would cause rsync to kill all processes owned by the
1960 current user. Yes, really! (Paul Haas, Martin Pool)
1962 * Fix test suite on Solaris. (Jos Backus, Martin Pool)
1964 * Fix minor memory leak in socket code. (Dave Dykstra, Martin
1967 * Fix --whole-file problem that caused it to be the default even
1968 for remote connections. (Martin Pool, Frank Schulz)

2002 * Make sure that supplementary groups are removed from a server
2003 process after changing uid and gid. (Ethan Benson) (Debian bug
2004 #132272, CVE CAN-2002-0080)
2008 * Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
2011 * Fixed problem that in many cases caused the error message
2012 unexpected read size of 0 in map_ptr
2013 and resulted in the wrong data being copied.
2015 * Fixed compilation errors on some systems caused by the use of
2016 "unsigned int64" in rsync.h.
2018 * Fixed problem on systems such as Sunos4 that do not support realloc
2019 on a NULL pointer; error was "out of memory in flist_expand".
2021 * Fix for rsync server processes hanging around after the client
2022 unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
2024 * Cope with BSD systems on which mkdir() will not accept a trailing
2029 * Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
2030 rsync still uses a custom version of zlib; you can not just link
2031 against a system library. See zlib/README.rsync)
2033 * Command to initiate connections is only shown with -vv, rather
2034 than -v as in 2.5.2. Output from plain -v is more similar to
2035 what was historically used so as not to break scripts that try
2036 to parse the output.
2038 * Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
2040 * Made the --write-batch and --read-batch options actually work
2041 and added documentation in the man page (Jos Backus)
2043 * If the daemon is unable to fork a child to accept a connection,
2044 print an error message. (Colin Walters)

2053 * Signedness security patch from Sebastian Krahmer
2054 <krahmer@suse.de> -- in some cases we were not sufficiently
2055 careful about reading integers from the network.
2059 * Fix possible string mangling in log files.
2061 * Fix for setting local address of outgoing sockets.
2063 * Better handling of hardlinks and devices on platforms with
2064 64-bit dev_t or ino_t.
2066 * Name resolution on machines supporting IPv6 is improved.
2068 * Fix for device nodes. (dann frazier) (Debian #129135)
2072 * With -v, rsync now shows the command used to initiate an ssh/rsh
2075 * --statistics now shows memory heap usage on platforms that
2078 * "The Ted T'so school of program optimization": make progress
2079 visible and people will think it's faster. (With --progress,
2080 rsync will show you how many files it has seen as it builds the
2081 file_list, giving some indication that it has not hung.)
2083 * Improvements to batch mode support. This is still experimental
2084 but testing would be welcome. (Jos Backus)
2086 * New --ignore-existing option, patch previously distributed with
2087 Vipul's Razor. (Debian #124286)

2116 * --progress and -P now show estimated data transfer rate (in a
2117 multiple of bytes/s) and estimated time to completion. (Rik
2120 * --no-detach option, required to run as a W32 service and also
2121 useful when running on Unix under daemontools, AIX's SRC, or a
2122 debugger. (Max Bowsher, Jos Backus)
2124 * Clearer error messages for some conditions.
2127 NEWS for rsync 2.5.0 (30 Nov 2001)
2128 Protocol: 25 (changed)
2129 Changes since 2.4.6:
2133 * Martin Pool <mbp@samba.org> is now a co-maintainer.
2137 * Support for LSB-compliant packaging <http://www.linuxbase.org/>
2139 * Shell wildcards are allowed in "auth users" lines.
2141 * Merged UNC rsync+ patch to support creation of standalone patch
2142 sets. By Bert J. Dempsey and Debra Weiss, updated by Jos
2143 Backus. <http://www.ils.unc.edu/i2dsi/unc_rsync+.html>
2145 * IPv6 support based on a patch from KAME.net, on systems
2146 including modern versions of Linux, Solaris, and HP-UX. Also
2147 includes IPv6 compatibility functions for old OSs by the
2148 Internet Software Consortium, Paul Vixie, the OpenSSH
2149 portability project, and OpenBSD.
2153 * Include/exclude cluestick: with -vv, print out whether files are
2154 included or excluded and why.
2156 * Many error messages have more friendly explanations and more
2159 * Manual page improvements plus scanty protocol documentation.
2161 * When running as --daemon in the background and using a "log
2162 file" rsyncd.conf directive, close the log file every time it is
2163 open when going to sleep on the socket. This allows the log
2164 file to get cleaned out by another process.
2166 * Change to using libpopt rather than getopt for processing
2167 options. This makes the code cleaner and the behaviour more
2168 consistent across platforms. popt is included and built if not
2169 installed on the platform.
2171 * More details in --version, including note about whether 64-bit
2172 files, symlinks and hardlinks are supported.
2174 * MD4 code may use less CPU cycles.
2176 * Use mkstemp on systems where it is secure. If we use mktemp,
2177 explain that we do it in a secure way.
2179 * --whole-file is the default when source and target are on the
2184 * Fix for various bugs causing rsync to hang.
2186 * Attempt to fix Large File Summit support on AIX.
2188 * Attempt to fix error handling lockup bug.
2190 * Give a non-0 exit code if *any* of the files we have been asked
2191 to transfer fail to transfer.
2193 * For log messages containing ridiculously long strings that might
2194 overflow a buffer rsync no longer aborts, but rather prints an
2195 ellipsis at the end of the string. (Patch from Ed Santiago.)
2199 * Improved support for UNICOS (tested on Cray T3E and Cray SV1)
2201 * autoconf2.52 (or later) is now required to rebuild the autoconf
2202 scripts. It is not required to simply build rsync.
