NEWS for rsync 3.0.8 (26 Mar 2011)
Protocol: 30 (unchanged)
Changes since 3.0.7:
BUG FIXES:
- Fixed two buffer-overflow issues: one where a directory path that is
exactly MAXPATHLEN was not handled correctly, and one handling a
--backup-dir that is extra extra large.
- Fixed a data-corruption issue when preserving hard-links without
preserving file ownership, and doing deletions either before or during
the transfer (CVE-2011-1097). This fixes some assert errors in the
hard-linking code, and some potential failed checksums (via -c) that
should have matched.
- Fixed a potential crash when an rsync daemon has a filter/exclude list
and the transfer is using ACLs or xattrs.
- Fixed a hang if a really large file is being processed by an rsync that
can't handle 64-bit numbers. Rsync will now complain about the file
being too big and skip it.
- For devices and special files, we now avoid gathering useless ACL and/or
xattr information for files that aren't being copied. (The un-copied
files are still put into the file list, but there's no need to gather
data that is not going to be used.) This ensures that if the user uses
--no-D, that rsync can't possibly complain about being unable to gather
extended information from special files that are in the file list (but
not in the transfer).
- Properly handle requesting remote filenames that start with a dash. This
avoids a potential error where a filename could be interpreted as a
(usually invalid) option.
- Fixed a bug in the comparing of upper-case letters in file suffixes for
--skip-compress.
- If an rsync daemon has a module configured without a path setting, rsync
will now disallow access to that module.
- If the destination arg is an empty string, it will be treated as a
reference to the current directory (as 2.x used to do).
- If rsync was compiled with a newer time-setting function (such as
lutimes), rsync will fall-back to an older function (such as utimes) on a
system where the newer function is not around. This helps to make the
rsync binary more portable in mixed-OS-release situations.
- Fixed a batch-file writing bug that would not write out the full set of
compatibility flags that the transfer was using. This fixes a potential
protocol problem for a batch file that contains a sender-side I/O error:
it would have been sent in a way that the batch-reader wasn't expecting.
- Some improvements to the hard-linking code to ensure that device-number
hashing is working right, and to supply more information if the hard-link
code fails.
- The --inplace code was improved to not search for an impossible checksum
position. The quadruple-verbose chunk[N] message will now mention when
an inplace chunk was handled by a seek rather than a read+write.
- Improved ACL mask handling, e.g. for Solaris.
- Fixed a bug that prevented --numeric-ids from disabling the translation
of user/group IDs for ACLs.
- Fixed an issue where an xattr and/or ACL transfer that used an alt-dest
option (e.g. --link-dest) could output an error trying to itemize the
changes against the alt-dest directory's xattr/ACL info but was instead
trying to access the not-yet-existing new destination directory.
- Improved xattr system-error messages to mention the full path to the
file.
- The --link-dest checking for identical symlinks now avoids considering
attribute differences that cannot be changed on the receiver.
- Avoid trying to read/write xattrs on certain file types for certain OSes.
Improved configure to set NO_SYMLINK_XATTRS, NO_DEVICE_XATTRS, and/or
NO_SPECIAL_XATTRS defines in config.h.
- Improved the unsafe-symlink errors messages.
- Fixed a bug setting xattrs on new files that aren't user writable.
- Avoid re-setting xattrs on a hard-linked file w/the same xattrs.
- Fixed a bug with --fake-super when copying files and dirs that aren't
user writable.
- Fixed a bug where a sparse file could have its last sparse block turned
into a real block when rsync sets the file size (requires ftruncate).
- If a temp-file name is too long, rsync now avoids truncating the name in
the middle of adjacent high-bit characters. This prevents a potential
filename error if the filesystem doesn't allow a name to contain an
invalid multi-byte sequence.
- If a muli-protocol socket connection fails (i.e., when contacting a
daemon), we now report all the failures, not just the last one. This
avoids losing a relevant error (e.g. an IPv4 connection-refused error)
that happened before the final error (e.g. an IPv6 protocol-not-supported
error).
- Generate a transfer error if we try to call chown with a -1 for a uid or
a gid (which is not settable).
- Fixed the working of --force when used with --one-file-system.
- Fix the popt arg parsing so that an option that doesn't take an arg will
reject an attempt to supply one (can configure --with-included-popt if
your system's popt library doesn't yet have this fix).
- A couple minor option tweaks to the support/rrsync script, and also some
regex changes that make vim highlighting happier.
- Fixed some issues in the support/mnt-excl script.
- Various manpage improvements.
ENHANCEMENTS:
- Added ".hg/" to the default cvs excludes (see -C & --cvs-exclude).
DEVELOPER RELATED:
- Use lchmod() whenever it is available (not just on symlinks).
- A couple fixes to the socketpair_tcp() routine.
- Updated the helper scripts in the packaging subdirectory.
- Renamed configure.in to configure.ac.
- Fixed configure's checking for iconv routines for newer OS X versions.
- Fixed the testsuite/xattrs.test script on OS X.
NEWS for rsync 3.0.7 (31 Dec 2009)
Protocol: 30 (unchanged)
Changes since 3.0.6:
BUG FIXES:
- Fixed a bogus free when using --xattrs with --backup.
- Avoid an error when --dry-run was trying to stat a prior hard-link file
that hasn't really been created.
- Fixed a problem with --compress (-z) where the receiving side could
return the error "inflate (token) returned -5".
- Fixed a bug where --delete-during could delete in a directory before it
noticed that the sending side sent an I/O error for that directory (both
sides of the transfer must be at least 3.0.7).
- Improved --skip-compress's error handling of bad character-sets and got
rid of a lingering debug fprintf().
- Fixed the daemon's conveyance of io_error value from the sender.
- An rsync daemon use seteuid() (when available) if it used setuid().
- Get the permissions right on a --fake-super transferred directory that
needs more owner permissions to emulate root behavior.
- An absolute-path filter rule (i.e. with a '/' modifier) no longer loses
its modifier when sending the filter rules to the remote rsync.
- Improved the "--delete does not work without -r or -d" message.
- Improved rsync's handling of --timeout to avoid a weird timeout case
where the sender could timeout even though it has recently written data
to the socket (but hasn't read data recently, due to the writing).
- Some misc manpage improvements.
- Fixed the chmod-temp-dir testsuite on a system without /var/tmp.
- Make sure that a timeout specified in the daemon's config is used as a
maximum timeout value when the user also specifies a timeout.
- Improved the error-exit reporting when rsync gets an error trying to
cleanup after an error: the initial error is reported.
- Improved configure's detection of IPv6 for solaris and cygwin.
- The AIX sysacls routines will now return ENOSYS if ENOTSUP is missing.
- Made our (only used if missing) getaddrinfo() routine use inet_pton()
(which we also provide) instead of inet_aton().
- The exit-related debug messages now mention the program's role so it is
clear who output what message.
DEVELOPER RELATED:
- Got rid of type-punned compiler warnings output by newer gcc versions.
- The Makefile now ensures that proto.h will be rebuilt if config.h changes.
- The testsuite no longer uses "id -u", so it works better on solaris.
NEWS for rsync 3.0.6 (8 May 2009)
Protocol: 30 (unchanged)
Changes since 3.0.5:
BUG FIXES:
- Fixed a --read-batch hang when rsync is reading a batch file that was
created from an incremental-recursion transfer.
- Fixed the daemon's socket code to handle the simultaneous arrival of
multiple connections.
- Fix --safe-links/--copy-unsafe-links to properly handle symlinks that
have consecutive slashes in the value.
- Fixed the parsing of an [IPv6_LITERAL_ADDR] when a USER@ is prefixed.
- The sender now skips a (bogus) symlink that has a 0-length value, which
avoids a transfer error in the receiver.
- Fixed a case where the sender could die with a tag-0 error if there was
an I/O during the sending of the file list.
- Fixed the rrsync script to avoid a server-side problem when -e is at the
start of the short options.
- Fixed a problem where a vanished directory could turn into an exit code
23 instead of the proper exit code 24.
- Fixed the --iconv conversion of symlinks when doing a local copy.
- Fixed a problem where --one-file-system was not stopping deletions on the
receiving side when a mount-point directory did not match a directory in
the transfer.
- Fixed the dropping of an ACL mask when no named ACL values were present.
- Fixed an ACL/xattr corruption issue where the --backup option could cause
rsync to associate the wrong ACL/xattr information with received files.
- Fixed the use of --xattrs with --only-write-batch.
- Fixed the use of --dry-run with --read-batch.
- Fixed configure's erroneous use of target.
- Fixed configure's --disable-debug option.
- Fixed a run-time issue for systems that can't find iconv_open() by adding
the --disable-iconv-open configure option.
- Complain and die if the user tries to combine --remove-source-files (or
the deprecated --remove-sent-files) with --read-batch.
- Fixed an failure transferring special files from Solaris to Linux.
NEWS for rsync 3.0.5 (28 Dec 2008)
Protocol: 30 (unchanged)
Changes since 3.0.4:
BUG FIXES:
- Initialize xattr data in a couple spots in the hlink code, which avoids a
crash when the xattr pointer's memory happens to start out non-zero.
Also fixed the itemizing of an alt-dest file's xattrs when hard-linking.
- Don't send a bogus "-" option to an older server if there were no short
options specified.
- Fixed skipping of unneeded updates in a batch file when incremental
recursion is active. Added a test for this. Made batch-mode handle
"redo" files properly (and without hanging).
- Fix the %P logfile escape when the daemon logs from inside a chroot.
- Fixed the use of -s (--protect-args) when used with a remote source or
destination that had an empty path (e.g. "host:"). Also fixed a problem
when -s was used when accessing a daemon via a remote-shell.
- Fixed the use of a dot-dir path (e.g. foo/./bar) inside a --files-from
file when the root of the transfer isn't the current directory.
- Fixed a bug with "-K --delete" removing symlinks to directories when
incremental recursion is active.
- Fixed a hard to trigger hang when using --remove-source-files.
- Got rid of an annoying delay when accessing a daemon via a remote-shell.
- Properly ignore (superfluous) source args on a --read-batch command.
- Improved the manpage's description of the '*' wildcard to remove the
confusing "non-empty" qualifier.
- Fixed reverse lookups in the compatibility-library version of
getnameinfo().
- Fixed a bug when using --sparse on a sparse file that has over 2GB of
consecutive sparse data.
- Avoid a hang when using at least 3 --verbose options on a transfer with a
client sender (which includes local copying).
- Fixed a problem with --delete-delay reporting an error when it was ready
to remove a directory that was now gone.
- Got rid of a bunch of "warn_unused_result" compiler warnings.
- If an ftruncate() on a received file fails, it now causes a partial-
transfer warning.
- Allow a path with a leading "//" to be preserved (CYGWIN only).
ENHANCEMENTS:
- Made the support/atomic-rsync script able to perform a fully atomic
update of the copied hierarchy when the destination is setup using a
particular symlink idiom.
NEWS for rsync 3.0.4 (6 Sep 2008)
Protocol: 30 (unchanged)
Changes since 3.0.3:
BUG FIXES:
- Fixed a bug in the hard-linking code where it would sometimes try to
allocate 0 bytes of memory (which fails on some OSes, such as AIX).
- Fixed the hard-linking of files from a device that has a device number
of 0 (which seems to be a common device number on NetBSD).
- Fixed the handling of a --partial-dir that cannot be created. This
particularly impacts the --delay-updates option (since the files cannot
be delayed without a partial-dir), and was potentially destructive if
the --remove-source-files was also specified.
- Fixed a couple issues in the --fake-super handling of xattrs when the
destination files have root-level attributes (e.g. selinux values) that
a non-root copy can't affect.
- Improved the keep-alive check in the generator to fire consistently in
incremental-recursion mode when --timeout is enabled.
- The --iconv option now converts the content of a symlink too, instead
of leaving it in the wrong character-set (requires 3.0.4 on both sides
of the transfer).
- When using --iconv, if a filename fails to convert on the receiving side,
this no longer makes deletions in the root-dir of the transfer fail
silently (the user now gets a warning about deletions being disabled
due to IO error as long as --ignore-errors was not specified).
- When using --iconv, if a server-side receiver can't convert a filename,
the error message sent back to the client no longer mangles the name
with the wrong charset conversion.
- Fixed a potential alignment issue in the IRIX ACL code when allocating
the initial "struct acl" object. Also, cast mallocs to avoid warnings.
- Changed some errors that were going to stdout to go to stderr.
- Made human_num() and human_dnum() able to output a negative number
(rather than outputting a cryptic string of punctuation).
ENHANCEMENTS:
- Rsync will avoid sending an -e option to the server if an older protocol
is requested (and thus the option would not be useful). This lets the
user specify the --protocol=29 option to access an overly-restrictive
server that is rejecting the protocol-30 use of -e to the server.
- Improved the message output for an RERR_PARTIAL exit.
DEVELOPER RELATED:
- The Makefile will not halt for just a timestamp change on the Makefile
or the configure files, only for actual changes in content.
- Changed some commands in the testsuite's xattrs.test that called "rsync"
instead of "$RSYNC".
- Enhanced the release scripts to be able to handle a branch release and
to do even more consistency checks on the files.
NEWS for rsync 3.0.3 (29 Jun 2008)
Protocol: 30 (unchanged)
Changes since 3.0.2:
BUG FIXES:
- Fixed a wildcard matching problem in the daemon when a module has
"use chroot" enabled.
- Fixed a crash bug in the hard-link code.
- Fixed the sending of xattr directory information when the code finds a
--link-dest or --copy-dest directory with unchanged xattrs -- the
destination directory now gets these unchanged xattrs properly applied.
- Fixed an xattr-sending glitch that could cause an "Internal abbrev"
error.
- Fixed the combination of --xattrs and --backup.
- The generator no longer allows a '.' dir to be excluded by a daemon-
exclude rule.
- Fixed deletion handling when copying a single, empty directory (with no
files) to a differently named, non-existent directory.
- Fixed the conversion of spaces into dashes in the %M log escape.
- Fixed several places in the code that were not returning the right
errno when a function failed.
- Fixed the backing up of a device or special file into a backup dir.
- Moved the setting of the socket options prior to the connect().
- If rsync exits in the middle of a --progress output, it now outputs a
newline to help prevent the progress line from being overwritten.
- Fixed a problem with how a destination path with a trailing slash or
a trailing dot-dir was compared against the daemon excludes.
- Fixed the sending of large (size > 16GB) files when talking to an older
rsync (protocols < 30): we now use a compatible block size limit.
- If a file's length is so huge that we overflow a checksum buffer count
(i.e. several hundred TB), warn the user and avoid sending an invalid
checksum struct over the wire.
- If a source arg is excluded, --relative no longer adds the excluded
arg's implied dirs to the transfer. This fix also made the exclude
check happen in the better place in the sending code.
- Use the overflow_exit() function for overflows, not out_of_memory().
- Improved the code to better handle a system that has only 32-bit file
offsets.
ENHANCEMENTS:
- The rsyncd.conf manpage now consistently refers to the parameters in
the daemon config file as "parameters".
- The description of the --inplace option was improved.
EXTRAS:
- Added a new script in the support directory, deny-rsync, which allows
an admin to (temporarily) replace the rsync command with a script that
sends an error message to the remote client via the rsync protocol.
DEVELOPER RELATED:
- Fixed a testcase failure if the tests are run as root and made some
compatibility improvements.
- Improved the daemon tests, including checking module comments, the
listing of files, and the ensuring that daemon excludes can't affect
a dot-dir arg.
- Improved some build rules for those that build in a separate directory
from the source, including better install rules for the man pages, and
the fixing of a proto.h-tstamp rule that could make the binaries get
rebuild without cause.
- Improved the testsuite to work around a problem with some utilities
(e.g. cp -p & touch -r) rounding sub-second timestamps.
- Ensure that the early patches don't cause any generated-file hunks to
bleed-over into patches that follow.
NEWS for rsync 3.0.2 (8 Apr 2008)
Protocol: 30 (unchanged)
Changes since 3.0.1:
BUG FIXES:
- Fixed a potential buffer overflow in the xattr code.
ENHANCEMENTS:
- None.
DEVELOPER RELATED:
- The RPM spec file was improved to install more useful files.
- A few developer-oriented scripts were moved from the support dir
to the packaging dir.
NEWS for rsync 3.0.1 (3 Apr 2008)
Protocol: 30 (unchanged)
Changes since 3.0.0:
NOTABLE CHANGES IN BEHAVIOR:
- Added the 'c'-flag to the itemizing of non-regular files so that the
itemized output doesn't get hidden if there were no attribute changes,
and also so that the itemizing of a --copy-links run will distinguish
between copying an identical non-regular file and the creation of a
revised version with a new value (e.g. a changed symlink referent, a
new device number, etc.).
BUG FIXES:
- Fixed a crash bug when a single-use rsync daemon (via remote shell) was
run without specifying a --config=FILE option.
- Fixed a crash when backing up a directory that has a default ACL.
- Fixed a bug in the handling of xattr values that could cause rsync to
not think that a file's extended attributes are up-to-date.
- Fixed the working of --fake-super with --link-dest and --xattrs.
- Fixed a hang when combining --dry-run with --remove-source-files.
- Fixed a bug with --iconv's handling of files that cannot be converted:
a failed name can no longer cause a transfer failure.
- Fixed the building of the rounding.h file on systems that need custom
CPPFLAGS to be used. Also improved the error reporting if the building
of rounding.h fails.
- Fixed the use of the --protect-args (-s) option when talking to a daemon.
- Fixed the --ignore-existing option's protection of files on the receiver
that are non-regular files on the sender (e.g. if a symlink or a dir on
the sender is trying to replace a file on the receiver). The reverse
protection (protecting a dir/symlink/device from being replaced by a
file) was already working.
- Fixed an assert failure if --hard-links is combined with an option that
can skip a file in a set of hard-linked files (i.e. --ignore-existing,
--append, etc.), without skipping all the files in the set.
- Avoid setting the modify time on a directory that already has the right
modify time set. This avoids tweaking the dir's ctime.
- Improved the daemon-exclude handling to do a better job of applying the
exclude rules to path entries. It also sends the user an error just as
if the files were actually missing (instead of silently ignoring the
user's args), and avoids sending the user the filter-action messages
for these non-user-initiated rules.
- Fixed some glitches with the dry-run code's missing-directory
handling, including a problem when combined with --fuzzy.
- Fixed some glitches with the skipped-directory handling.
- Fixed the 'T'-flag itemizing of symlinks when --time isn't preserved.
- Fixed a glitch in the itemizing of permissions with the -E option.
- The --append option's restricting of transfers to those that add data no
longer prevents the updating of non-content changes to otherwise up-to-
date files (i.e. those with the same content but differing permissions,
ownership, xattrs, etc.).
- Don't allow --fake-super to be specified with -XX (double --xattrs)
because the options conflict. If a daemon has "fake super" enabled,
it automatically downgrades a -XX request to -X.
- Fixed a couple bugs in the parsing of daemon-config excludes that could
make a floating exclude rule get treated as matching an absolute path.
- A daemon doesn't try to auto-refuse the "iconv" option if iconv-support
wasn't compiled in to the daemon (avoiding a warning in the logs).
- Fixed the inclusion of per-dir merge files from implied dirs.
- Fixed the support/rrsync script to work with the latest options that
rsync sends (including its flag-specifying use of -e to the server).
ENHANCEMENTS:
- Added the --old-dirs (--old-d) option to make it easier for a user to
ask for file-listings with older rsync versions (this is easier than
having to type "-r --exclude='/*/*'" manually).
- When getting an error while asking an older rsync daemon for a file
listing, rsync will try to notice if the error is a rejection of the
--dirs (-d) option and let the user know how to work around the issue.
- Added a few more --no-OPTION overrides.
- Improved the documentation of the --append option.
- Improved the documentation of the filter/exclude/include daemon
parameters.
INTERNAL:
- Fixed a couple minor bugs in the included popt library (ones which I
sent to the official popt project for inclusion in the 1.14 release).
- Fixed a stat() call that should have been do_stat() so that the proper
normal/64-bit stat() function gets called. (Was in an area that should
not have caused problems, though.)
- Changed the file-glob code to do a directory scan without using the
"glob" and "glob.h". This lets us do the globbing with less memory
churn, and also avoid adding daemon-excluded items to the returned
args.
DEVELOPER RELATED:
- The configure script tries to get the user's compiler to not warn about
unused function parameters if the build is not including one or more of
the ACL/xattrs/iconv features.
- The configure script now has better checks for figuring out if the
included popt code should be used or not.
- Fixed two testsuite glitches: avoid a failure if someone's "cd" command
outputs the current directory when cd-ing to a relative path, and made
the itemized test query how rsync was built to determine if it should
expect hard-linked symlinks or not.
- Updated the testsuite to verify that various bug fixes remain fixed.
- The RPM spec file was updated to have: (1) comments for how to use the
rsync-patch tar file, and (2) an /etc/xinetd.d/rsync file.
- Updated the build scripts to work with a revised FTP directory
structure.
NEWS for rsync 3.0.0 (1 Mar 2008)
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.)
Also, exclude rules no longer have a partial effect on implied dirs.
- Requesting a remote file-listing 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.
- In --dry-run mode, the last line of the verbose summary text is output
with a "(DRY RUN)" suffix to help remind you that no updates were made.
Similarly, --only-write-batch outputs "(BATCH ONLY)".
- A writable rsync daemon with "use chroot" disabled now defaults to a
symlink-munging behavior designed to make symlinks safer while also
allowing absolute symlinks to be stored and retrieved. This also has
the effect of making symlinks unusable while they're in the daemon's
hierarchy. See the daemon's "munge symlinks" parameter for details.
- 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. This means that your wrapper script that starts the rsync
daemon should be made to handle lock-breaking (if you want any automatic
breaking of locks to be done).
BUG FIXES:
- A daemon with "use chroot = no" and excluded items listed in the daemon
config file now properly checks an absolute-path arg specified for these
options: --compare-dest, --link-dest, --copy-dest, --partial-dir,
--backup-dir, --temp-dir, and --files-from.
- A daemon can now be told to disable all user- and group-name translation
on a per-module basis. This avoids a potential problem with a writable
daemon module that has "use chroot" enabled -- if precautions weren't
taken, a user could try to add a missing library and get rsync to use
it. This makes rsync safer by default, and more configurable when id-
translation is not desired. See the daemon's "numeric ids" parameter
for full details.
- A chroot daemon can now indicate which part of its path should affect the
chroot call, and which part should become an inside-chroot path for the
module. This allows you to have outside-the-transfer paths (such as for
libraries) even when you enable chroot protection. The idiom used in the
rsyncd.conf file is: path = /chroot/dirs/./dirs/inside
- If a file's data arrived successfully on the receiving side but the
rename of the temporary file to the destination file failed AND the
--remove-source-files (or the deprecated --remove-sent-files) option
was specified, rsync no longer erroneously removes the associated
source file.
- Fixed the output of -ii when combined with one of the --*-dest options:
it now itemizes all the items, not just the changed ones.
- Made the output of all file types consistent when using a --*-dest
option. Prior versions would output too many creation events for
matching items.
- 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.
- 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 problem with the --out-format (aka --log-format) option %f: it
no longer outputs superfluous directory info for a non-daemon rsync.
- 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.
- 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.
- Make sure that directory permissions of a newly-created destination
directory are handled right when --perms is left off.
- The itemized output of a newly-created destination directory is now
output as a creation event, not a change event.
- Improved --hard-link so that more corner cases are handled correctly
when combined with options such as --link-dest and/or --ignore-existing.
- The --append option no longer updates a file that has the same size.
- Fixed a bug when combining --backup and --backup-dir with --inplace:
any missing backup directories are now created.
- Fixed a bug when using --backup and --inplace with --whole-file or
--read-batch: backup files are actually created now.
- The daemon pidfile is checked and created sooner in the startup sequence.
- If a daemon module's "path" value is not an absolute pathname, the code
now makes it absolute internally (making it work properly).
- Ensure that a temporary file always has owner-write permission while we
are writing to it. This avoids problems with some network filesystems
when transfering read-only files.
- Any errors output about password-file reading no longer cause an error at
the end of the run about a partial transfer.
- The --read-batch option for protocol 30 now ensures that several more
options are set correctly for the current batch file: --iconv, --acls,
--xattrs, --inplace, --append, and --append-verify.
- Using --only-write-batch to a daemon receiver now works properly (older
versions would update some files while writing the batch).
- Avoid outputting a "file has vanished" message when the file is a broken
symlink and --copy-unsafe-links or --copy-dirlinks is used (the code
already handled this for --copy-links).
- Fixed the combination of --only-write-batch and --dry-run.
- Fixed rsync's ability to remove files that are not writable by the file's
owner when rsync is running as the same user.
- When transferring large files, the sender's hashtable of checksums is
kept at a more reasonable state of fullness (no more than 80% full) so
that the scanning of the hashtable will not bog down as the number of
blocks increases.
ENHANCEMENTS:
- 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). For example, 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 preserve 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" parameter 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.
- A new daemon config parameter, "charset", lets you control the character-
set that is used during an --iconv transfer to/from a daemon module. You
can also set your daemon to refuse "no-iconv" if you want to force the
client to use an --iconv transfer (requiring an rsync 3.x client).
- Added the --skip-compress=LIST option to override the default list of
file suffixes that will not be compressed when using --compress (-z).
- The daemon's default for "dont compress" was extended to include:
*.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
The name-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.
- Rsync checks all the alternate-destination args for validity (e.g.
--link-dest). This lets the user know when they specified a directory
that does not exist.
- If we get an ENOSYS error setting the time on a symlink, we don't
complain about it anymore (for those systems that even support the
setting of the modify-time on a symlink).
- 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.
- Added the --contimeout=SECONDS option that lets the user specify a
connection timeout for rsync daemon access.
- 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.
- Rsync now supports a lot more --no-OPTION override options.
INTERNAL:
- 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 is also faster
than the glibc version of qsort() and mergesort().
- Rsync now supports the transfer of 64-bit timestamps (time_t values).
- Made the file-deletion code use a little less stack when recursing
through a directory hierarchy of extraneous files.
- Fixed a build problem with older (2.x) versions of gcc.
- Added some isType() functions that make dealing with signed characters
easier without forcing variables via casts.
- Changed strcat/strcpy/sprintf function calls to use safer versions.
- Upgraded the included popt version to 1.10.2 and improved its use of
string-handling functions.
- Added missing prototypes for compatibility functions from the lib dir.
- Configure determines if iconv() has a const arg, allowing us to avoid a
compiler warning.
- Made the sending of some numbers more efficient for protocol 30.
- Make sure that a daemon process doesn't mind if the client was weird and
omitted the --server option.
- There are more internal logging categories available in protocol 30 than
the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new
categories allow some errors and warnings to go to stderr without causing
an erroneous end-of-run warning about some files not being able to be
transferred.
- Improved the use of "const" on pointers.
- Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
older sections of a pool's memory.
- 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.
DEVELOPER RELATED:
- Rsync is now licensed under the GPLv3 or later.
- Rsync is now being maintained in a "git" repository instead of CVS
(though the old CVS repository still exists for historical access).
Several maintenance scripts were updated to work with git.
- Generated files are no longer committed into the source repository. The
autoconf and autoheader commands are now automatically run during the
normal use of "configure" and "make". The latest dev versions of all
generated files can also be copied from the samba.org web site (see the
prepare-source script's fetch option).
- The "patches" directory of diff files is now built from branches in the
rsync git repository (branch patch/FOO creates file patches/FOO.diff).
This directory is now distributed in a separate separate tar file named
rsync-patches-VERSION.tar.gz instead of the main rsync-VERSION.tar.gz.
- The proto.h file is now built using a simple perl script rather than a
complex awk script, which proved to be more widely compatible.
- 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 filesystem 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 safer 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).
- The csprotocol.txt file was updated to mention the daemon protocol change
in the 3.0.0 release.
NEWS for rsync 2.6.9 (6 Nov 2006)
Protocol: 29 (unchanged)
Changes since 2.6.8:
BUG FIXES:
- If rsync is interrupted via a handled signal (such as SIGINT), it will
once again clean-up its temp file from the destination dir.
- Fixed an overzealous sanitizing bug in the handling of the --link-dest,
