-NEWS for rsync 3.0.0 (UNRELEASED)
-Protocol: 30 (changed)
-Changes since 2.6.9:
-
- NOTABLE CHANGES IN BEHAVIOR:
-
- - The handling of implied directories when using --relative has changed to
- send them as directories (e.g. no implied dir is ever sent as a symlink).
- This avoids unexpected behavior and should not adversely affect most
- people. If you're one of those rare individuals who relied upon having
- an implied dir be duplicated as a symlink, you should specify the
- transfer of the symlink and the transfer of the referent directory as
- separate args. (See also --keep-dirlinks and --no-implied-dirs.)
-
- - Requesting a remote file list without specifying -r (--recursive) now
- sends the -d (--dirs) option to the remote rsync rather than sending -r
- along with an extra exclude of /*/*. If the remote rsync does not
- understand the -d option (i.e. it is 2.6.3 or older), you will need to
- either turn off -d (--no-d), or specify -r --exclude='/*/*' manually.
+NEWS for rsync 3.1.0 (28 Sep 2013)
+Protocol: 31 (changed)
+Changes since 3.0.9:
+
+ OUTPUT CHANGES:
+
+ - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the
+ --human-readable option for a way to turn it off. See also the daemon's
+ "log format" parameter and related command-line options (including
+ --out-format) for a modifier that can be used to request digit-grouping
+ or human-readable output in log escapes. (Note that log output is
+ unchanged by default.)
+
+ - The --list-only option is now affected by the --human-readable setting.
+ It will display digit groupings by default, and unit suffixes if higher
+ levels of readability are requested. Also, the column width for the size
+ output has increased from 11 to 14 characters when human readability is
+ enabled. Use --no-h to get the old-style output and column size.
+
+ - The output of the --progress option has changed: the string "xfer" was
+ shortened to "xfr", and the string "to-check" was shortened to "to-chk",
+ both designed to make room for the (by default) wider display of file
+ size numbers without making the total line-length longer. Also, when
+ incremental recursion is enabled, the string "ir-chk" will be used
+ instead of "to-chk" up until the incremental-recursion scan is done,
+ letting you know that the value to check and the total value will still
+ be increasing as new files are found.
+
+ - Enhanced the --stats output: 1) to mention how many files were created
+ (protocol >= 28), 2) to mention how many files were deleted (a new line
+ for protocol 31, but only output when --delete is in effect), and 3) to
+ follow the file-count, created-count, and deleted-count with a subcount
+ list that shows the counts by type. The wording of the transferred count
+ has also changed so that it is clearer that it is only a count of regular
+ files.
BUG FIXES:
- - Fixed the output of -ii when combined with one of the --*-dest options:
- it now itemizes all the items, not just the changed ones.
+ - Fixed a bug in the iconv code when EINVAL or EILSEQ is returned with a
+ full output buffer.
- - Made the output of all file types consistent when using a --*-dest
- option. Prior versions would output too many creation events for
- matching items.
+ - Fixed some rare bugs in --iconv processing that might cause a multibyte
+ character to get translated incorrectly.
- - The code that waits for a child pid now handles being interrupted by a
- signal. This fixes a problem with the pre-xfer exec function not being
- able to get the exit status from the script.
+ - Fixed a bogus "vanished file" error if some files were specified with
+ "./" prefixes and others were not.
- - A negated filter rule (i.e. with a '!' modifier) no longer loses the
- negation when sending the filter rules to the remote rsync.
+ - Fixed a bug in --sparse where an extra gap could get inserted after a
+ partial write.
- - Fixed a problem with the --out-format (aka --log-format) option %f: it
- no longer outputs superfluous directory info for a non-daemon rsync.
+ - Changed the way --progress overwrites its prior output in order to make
+ it nearly impossible for the progress to get overwritten by an error.
- - Fixed a problem with -vv (double --verbose) and --stats when "pushing"
- files (which includes local copies). Version 2.6.9 would complete the
- copy, but exit with an error when the receiver output its memory stats.
+ - Improved the propagation of abnormal-exit error messages. This should
+ help the client side to receive errors from the server when it is exiting
+ abnormally, and should also avoid dying with an "connection unexpectedly
+ closed" exit when the closed connection is really expected.
- - If --password-file is used on a non-daemon transfer, rsync now complains
- and exits. This should help users figure out that they can't use this
- option to control a remote shell's password prompt.
+ - The sender now checks each file it plans to remove to ensure that it
+ hasn't changed from the first stat's info. This helps to avoid losing
+ file data when the user is not using the option in a safe manner.
- - Make sure that directory permissions of a newly-created destination
- directory are handled right when --perms is left off.
+ - Fixed a data-duplication bug in the compress option that made compression
+ less efficient. This improves protocol 31 onward, while behaving in a
+ compatible (buggy) manner with older rsync protocols.
- - The itemized output of a newly-created destination directory is now
- output as a creation event, not a change event.
+ - When creating a temp-file, rsync is now a bit smarter about it dot-char
+ choices, which can fix a problem on OS X with names that start with "..".
- - Improved --hard-link so that more corner cases are handled correctly
- when combined with options such as --link-dest and/or --ignore-existing.
+ - Rsync now sets a cleanup flag for --inplace and --append transfers that
+ will flush the write buffer if the transfer aborts. This ensures that
+ more received data gets written out to the disk on an aborted transfer
+ (which is quite helpful on a slow, flaky connection).
- - The --append option no longer updates a file that has the same size.
+ - The reads that map_ptr() now does are aligned on 1K boundaries. This
+ helps some filesystems and/or files that don't like unaligned reads.
- - Fixed a bug when combining --backup and --backup-dir with --inplace:
- any missing backup directories are now created.
+ - Fix an issue in the msleep() function if time jumps backwards.
- - Fixed a bug when using --backup and --inplace with --whole-file or
- --read-batch: backup files are actually created now.
+ - Fix daemon-server module-name splitting bug where an arg would get split
+ even if --protect-args was used.
- - Starting up an extra copy of an rsync daemon will not clobber the pidfile
- for the running daemon -- if the pidfile exists, the new daemon will exit
- with an error.
+ ENHANCEMENTS:
- - The daemon pidfile is checked and created sooner in the startup sequence.
+ - Added the --remote-option=OPT (-M OPT) command-line option that is useful
+ for things like sending a remote --log-file=FILE or --fake-super option.
- - If a daemon module's "path" value is not an absolute pathname, the code
- now makes it absolute internally (making it work properly).
+ - Added the --info=FLAGS and --debug=FLAGS options to allow finer-grained
+ control over what is output. Added an extra type of --progress output
+ using --info=progress2.
- - Ensure that a temporary file always has owner-write permission while we
- are writing to it. This avoids problems with some network filesystems.
+ - The --msgs2stderr option can help with debugging rsync by allowing the
+ debug messages to get output to stderr rather than travel via the socket
+ protocol.
- - Any errors output about password-file reading no longer cause an error at
- the end of the run about a partial transfer.
+ - Added the --delete-missing-args and --ignore-missing-args options to
+ either delete or ignore user-specified files on the receiver that are
+ missing on the sender (normally the absence of user-specified files
+ generates an error).
- ENHANCEMENTS:
+ - Added a "T" (terabyte) category to the --human-readable size suffixes.
- - A new incremental-recursion algorithm is now used when rsync is talking
- to another 3.x version. This starts the transfer going more quickly
- (before all the files have been found), and requires much less memory.
- See the --recursive option in the manpage for some restrictions.
-
- - Lowered memory use in the non-incremental-recursion algorithm for typical
- option values (usually saving from 21-29 bytes per file).
-
- - The default --delete algorithm is now --delete-during when talking to a
- 3.x rsync. This is a faster scan than using --delete-before (which is
- the default when talking to older rsync versions), and is compatible with
- the new incremental recursion mode.
-
- - Rsync now allows multiple remote-source args to be specified rather than
- having to rely on a special space-splitting side-effect of the remote-
- shell. Additional remote args must specify the same host or an empty one
- (e.g. empty: :file1 or ::module/file2). This means that local use of
- brace expansion now works: rsync -av host:dir/{f1,f2} .
-
- - Added the --protect-args (-s) option, that tells rsync to send most of
- the command-line args at the start of the transfer rather than as args
- to the remote-shell command. This protects them from space-splitting,
- and only interprets basic wildcard special shell characters (*?[).
-
- - Added the --delete-delay option, which is a more efficient way to delete
- files at the end of the transfer without needing a separate delete pass.
-
- - Added the --acls (-A) option to preserve Access Control Lists. This is
- an improved version of the prior patch that was available, and it even
- supports OS X ACLs. If you need to have backward compatibility with old,
- acl-patched versions of rsync, apply the acls.diff file from the patches
- dir.
-
- - Added the --xattrs (-X) option to preserver extended attributes. This is
- an improved version of the prior patch that was available, and it even
- supports OS X xattrs (which includes their resource fork data). If you
- need to have backward compatibility with old, xattr-patched versions of
- rsync, apply the xattrs.diff file from the patches dir.
-
- - Added the --fake-super option that allows a non-super user to preserve
- all attributes of a file by using a special extended-attribute idiom.
- It even supports the storing of foreign ACL data on your backup server.
- There is also an analogous "fake super" option for an rsync daemon.
-
- - Added the --iconv option, which allows rsync to convert filenames from
- one character-set to another during the transfer. The default is to make
- this feature available as long as your system has iconv_open(). If
- compilation fails, specify --disable-iconv to configure, and then
- rebuild. If you want rsync to perform character-set conversions by
- default, you can specify --enable-iconv=CONVERT_STRING with the default
- value for the --iconv option that you wish to use. For example,
- "--enable-iconv=." is a good choice. See the rsync manpage for an
- explanation of the --iconv option's settings.
-
- - Added the --skip-compress=LIST option to override the default list of
- file suffixes that will not be compressed when using --compress.
-
- - The daemon's default for "dont compress" was extended to include:
- *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
- The matching routine was also optimized to run more quickly.
-
- - The --max-delete option now outputs a warning if it skipped any file
- deletions, including a count of how many deletions were skipped. (Older
- versions just silently stopped deleting things.)
-
- - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
- about extraneous files without deleting anything. If you're not sure
- what version the client is, you can use the less-obvious --max-delete=-1,
- as both old and new versions will treat that as the same request (though
- older versions don't warn).
-
- - The --hard-link option now uses less memory on both the sending and
- receiving side for all protocol versions. For protocol 30, the use of a
- hashtable on the sending side allows us to more efficiently convey to the
- receiver what files are linked together. This reduces the amount of data
- sent over the socket by a considerable margin (rather than adding more
- data), and limits the in-memory storage of the device+inode information
- to just the sending side for the new protocol 30, or to the receiving
- side when speaking an older protocol (note that older rsync versions kept
- the device+inode information on both sides).
-
- - The filter rules now support a perishable ("p") modifier that marks rules
- that should not have an effect in a directory that is being deleted. e.g.
- -f '-p .svn/' would only affect "live" .svn directories.
-
- - If we get an error setting the time on a symlink, we don't complain about
- it anymore (since some operating systems don't support that, and it's not
- that important).
-
- - Protocol 30 now uses MD5 checksums instead of MD4.
-
- - Changed the --append option to not checksum the existing data in the
- destination file, which speeds up file appending.
-
- - Added the --append-verify option, which works like the older --append
- option (verifying the existing data in the destination file). For
- compatibility with older rsync versions, any use of --append that is
- talking protocol 29 or older will revert to the --append-verify method.
-
- - Documented and extended the support for the RSYNC_CONNECT_PROG variable
- that can be used to enhance the client side of a daemon connection.
-
- - Improved the dashes and double-quotes in the nroff manpage output.
-
- - We now support a lot more --no-OPTION override options.
+ - Added the --usermap/--groupmap/--chown options for manipulating file
+ ownership during the copy.
- INTERNAL:
+ - Added the "%C" escape to the log-output handling, which will output the
+ MD5 checksum of any transferred file, or all files if --checksum was
+ specified (when protocol 30 or above is in effect).
+
+ - Added the "reverse lookup" parameter to the rsync daemon config file to
+ allow reverse-DNS lookups to be disabled.
+
+ - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can
+ be disabled via "forward lookup" parameter (defaults to enabled).
+
+ - Added a way for more than one group to be specified in the daemon's
+ config file, including a way to specify that you want all of the
+ specified user's groups without having to name them. Also changed the
+ daemon to complain about an inability to set explicitly-specified uid/gid
+ values, even when not run by a super-user.
+
+ - The daemon now tries to send the user the error messages from the
+ pre-xfer exec script when it fails.
+
+ - Improved the use of alt-dest options into an existing hierarchy of files:
+ If a match is found in an alt-dir, it takes precedence over an existing
+ file. (We'll need to wait for a future version before attribute-changes
+ on otherwise unchanged files are safe when using an existing hierarchy.)
+
+ - Added per-user authorization options and group-authorization support to
+ the daemon's "auth users" parameter.
+
+ - Added a way to reference environment variables in a daemon's config file
+ (using %VAR% references).
+
+ - When replacing a non-dir with a symlink/hard-link/device/special-file,
+ the update should now be done in an atomic manner.
+
+ - Avoid re-sending xattr info for hard-linked files w/the same xattrs
+ (protocol 31).
+
+ - The backup code was improved to use better logic maintaining the backup
+ directory hierarchy. Also, when a file is being backed up, rsync tries
+ to hard-link it into place so that the upcoming replacement of the
+ destination file will be atomic (for the normal, non-inplace logic).
+
+ - Added the ability to synchronize nano-second modified times.
+
+ - Added a few more default suffixes for the "dont compress" settings.
+
+ - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow
+ the default for the --protect-args command-line option to be overridden.
- - The file-list sorting algorithm now uses a sort that keeps any same-
- named items in the same order as they were specified. This allows
- rsync to always ensure that the first of the duplicates is the one
- that will be included in the copy. The new sort was also faster
- than the glibc version of qsort() and mergesort() in my testing.
+ - Added the --preallocate command-line option.
- - Rsync now supports the transfer of 64-bit timestamps (time_t values).
+ - Allow --password-file=- to read the password from stdin (filename "-").
- - Fixed a build problem with older (2.x) versions of gcc.
+ - Rsync now comes packaged with an rsync-ssl helper script that can be
+ used to contact a remote rsync daemon using a piped-stunnel command.
+ It also includes an stunnel config file to run the server side to
+ support ssl daemon connections. See the packaging/lsb/rsync.spec
+ file for one way to package the resulting files. (Suggestions for
+ how to make this even easier to install & use are welcomed.)
- - Added some isType() functions that make dealing with signed characters
- easier without forcing variables via casts.
+ - Improved the speed of some --inplace updates when there are lots of
+ identical checksum blocks that end up being unusable.
- - Changed strcat/strcpy/sprintf function calls to use safer versions.
+ - Added the --outbuf=N|L|B option for choosing the output buffering.
- - Upgraded the included popt version to 1.10.2 and improved its use of
- string-handling functions.
+ - Repeating the --fuzzy option now causes the code to look for fuzzy
+ matches inside alt-dest directories too.
- - Added missing prototypes for compatibility functions from the lib dir.
+ - The --chmod option now supports numeric modes, e.g. --chmod=644,D755
- - Configure determines if iconv() has a const arg, allowing us to avoid a
- compiler warning.
+ - Added some Solaris xattr code.
- - Made the sending of some numbers more efficient for protocol 30.
+ - Made an rsync daemon (the listening process) exit with a 0 status when
+ it was signaled to die. This helps launchd.
- - Make sure that a daemon process doesn't mind if the client was weird and
- omitted the --server option.
+ - Improved the RSYNC_* environment variables for the pre-xfer exec script:
+ when a daemon is sent multiple request args, they are now joined into a
+ single return value (separated by spaces) so that the RSYNC_REQUEST
+ environment variable is accurate for any "pre-xfer exec". The values in
+ RSYNC_ARG# vars are no longer truncated at the "." arg (prior to the
+ request dirs/files), so that all the requested values are also listed
+ (separately) in RSYNC_ARG# variables.
- - Improved the use of "const" on pointers.
+ EXTRAS:
- - Improved J.W.'s pool_alloc routines to add a way of freeing older
- sections of a pool's memory.
+ - Added an "instant-rsyncd" script to the support directory, which makes
+ it easy to configure a simple rsync daemon in the current directory.
- - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
- some new code (derived from samba, derived from PostgreSQL) that has a
- better license than the old code.
+ - Added the "mapfrom" and "mapto" scripts to the support directory, which
+ makes it easier to do user/group mapping in a local transfer based on
+ passwd/group files from another machine.
+
+ - There's a new, improved version of the lsh script in the support dir:
+ it's written in perl and supports -u without resorting to using sudo
+ (when run as root). The old shell version is now named lsh.sh.
+
+ - There is a helper script named rsync-slash-strip in the support directory
+ for anyone that wants to change the way rsync handles args with trailing
+ slashes. (e.g. arg/ would get stripped to arg while arg/. would turn into
+ arg/).
+
+ INTERNAL:
+
+ - The I/O code was rewritten to be simpler and do bigger buffered reads
+ over the socket. The I/O between the receiver and the generator was
+ changed to be standard multiplexed-I/O (like that over the socket).
+
+ - The sender tries to use any dead time while the generator is looking for
+ files to transfer in order to do sender-side directory scanning in a more
+ parallel manner.
+
+ - A daemon can now inform a client about a daemon-configured timeout value
+ so that the client can assist in the keep-alive activity (protocol 31).
+
+ - The filter code received some refactoring to make it more extendible, to
+ read better, and do better sanity checking.
+
+ - Really big numbers are now output using our own big-num routine rather
+ than casting them to a double and using a %.0f conversion.
+
+ - The pool_alloc library has received some minor improvements in alignment
+ handling.
+
+ - Added init_stat_x() function to avoid duplication of acl/xattr init code.
+
+ - The included zlib was upgraded from 1.2.3 to 1.2.8.
+
+ - Rsync can now be compiled to use an unmodified zlib library instead of
+ the tweaked one that is included with rsync. This will eventually
+ become the default, at which point we'll start the countdown to removing
+ the included zlib. Until then, feel free to configure using:
+
+ ./configure --with-included-zlib=no
DEVELOPER RELATED:
- - Rsync is now licensed under the GPLv3 or later.
-
- - When running the tests, we now put our per-test temp dirs into a sub-
- directory named testtmp (which is created, if missing). This allows
- someone to symlink the testtmp directory to another filesystem (which is
- useful if the build dir's filesystem does not support ACLs and xattrs,
- but another file system does).
-
- - Rsync now has a way of handling protocol-version changes during the
- development of a new protocol version. This causes any out-of-sync
- versions to speak an older protocol rather than fail in a cryptic manner.
- This addition makes it safe to deploy a pre-release version that may
- interact with the public. This new exchange of sub-version info does not
- interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
- does not have enough range to allow the main protocol number to be
- incremented for every minor tweak in that happens during development).
+ - Added more conditional debug output.
+
+ - Fixed some build issues for android and minix.
