if it has no read permission).
- Fix preservation of a symlink's system xattrs (e.g. selinux) on Linux.
- Fix a memory leak in the xattr code.
- Fixed a bug with --delete-excluded when a filter merge file has a rule
that specifies a receiver-only side restriction.
- Fix a bug with the modifying of unwritable directories.
- Fix --fake-super's interaction with --link-dest same-file comparisons.
- Fix the updating of the curr_dir buffer to avoid a duplicate slash.
- Fix the directory permissions on an implied dot-dir when using --relative
(e.g. /outside/path/././send/path).
- Fixed some too-long sleeping instances when using --bwlimit.
- Fixed when symlink ownership difference-checking gets compiled into
unchanged_attrs().

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.
- 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.
Approved by Alistair Crooks.
- 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.
Approved by Alistair Crooks.
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.
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.
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.
mostly improvements in speed of execution (usually up by around factor 10)
and memory use (the same factor down). Please see <http://samba.rsync.org/>
or ${WRKSRC}/CHANGES for more detailed information.
Changes between 3.0.0 and 3.0.1:
- New flag "c" for itemizing non-regular files.
- Fix crash when running rsyncd without --config-file= .
- Fix crash when backing up a directory which has default ACLs.
- 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 preventing gobbled file names from causing
transfer failures.
- Fixed the use of the --protect-args (-s) option when talking to a daemon.
- Fixed the --ignore-existing symlink problems.
- Avoid setting the mtime on a directory that already has the right one.
- Improved the daemon-exclude handling.
- Fixed a glitch in the itemizing of permissions with the -E option.
- Various other bugfixes.
- Fixed a couple minor bugs in the included popt library.
- Fixed a stat() call that should have been do_stat() for 64-bit
functionality.
- Changed the file-glob code to do a more memory efficient directory scan.
Approved-by: tron
see <http://samba.rsync.org/> or ${WRKSRC}/CHANGES for more information.

the daemon's config file): RSYNC_PID.
NEWS for rsync 2.6.8 (22 Apr 2006)
Protocol: 29 (unchanged)
Changes since 2.6.7:
BUG FIXES:
- Fixed a bug in the exclude code where an anchored exclude without any
wildcards fails to match an absolute source arg, but only when --relative
is in effect.
- Improved the I/O code for the generator to fix a potential hang when the
receiver gets an EOF on the socket but the generator's select() call
never indicates that the socket is writable for it to be notified about
the EOF. (This can happen when using stunnel).
- Fixed a problem with the file-reading code where a failed read (such as
that caused by a bad sector) would not advance the file's read-position
beyond the failed read's data.
- Fixed a logging bug where the "log file" directive was not being honored
in a single-use daemon (one spawned by a remote-shell connection or by
init).
- If rsync cannot honor the --delete option, we output an error and exit
instead of silently ignoring the option.
- Fixed a bug in the --link-dest code that prevented special files (such as
fifos) from being linked.
- The ability to hard-link symlinks and special files is now determined at
configure time instead of at runtime. This fixes a bug with --link-dest
creating a hard-link to a symlink's referent on a BSD system.
ENHANCEMENTS:
- In daemon mode, if rsync fails to bind to the requested port, the
error(s) returned by socket() and/or bind() are now logged.
- When we output a fatal error, we now output the version of rsync in the
message.
- Improved the documentation for the --owner and --group options.
- The rsyncstats script in "support" has an improved line-parsing regex
that is easier to read and also makes it to parse syslog-generated lines.
- A new script in "support": file-attr-restore, can be used to restore the
attributes of a file-set (the permissions, ownership, and group info)
taken from the cached output of a "find ARG... -ls" command.
NEWS for rsync 2.6.7 (11 Mar 2006)
Protocol: 29 (unchanged)
Changes since 2.6.6:
OUTPUT CHANGES:
- The letter 'D' in the itemized output was being used for both devices
(character or block) as well as other special files (such as fifos and
named sockets). This has changed to separate non-device special files
under the 'S' designation (e.g. "cS+++++++ path/fifo"). See also the
"--specials" option, below.
- The way rsync escapes unreadable characters has changed. First, rsync
now has support for recognizing valid multibyte character sequences in
your current locale, allowing it to escape fewer characters than before
for a locale such as UTF-8. Second, it now uses an escape idiom of
"\#123", which is the literal string "\#" followed by exactly 3 octal
digits. Rsync no longer doubles a backslash character in a filename
(e.g. it used to output "foo\\bar" when copying "foo\bar") -- now it only
escapes a backslash that is followed by a hash-sign and 3 digits (0-9)
(e.g. it will output "foo\#134#789" when copying "foo\#789"). See also
the --8-bit-output (-8) option, mentioned below.
Script writers: the local rsync is the one that outputs escaped names,
so if you need to support unescaping of filenames for older rsyncs, I'd
suggest that you parse the output of "rsync --version" and only use the
old unescaping rules for 2.6.5 and 2.6.6.
BUG FIXES:
(LOTS)
ENHANCEMENTS:
- Added the --append option that makes rsync append data onto files that
are longer on the source than the destination (this includes new files).
- Added the --min-size=SIZE option to exclude small files from the
transfer.
- Added the --compress-level option to allow you to set how aggressive
rsync's compression should be (this option implies --compress).
- Enhanced the parsing of the SIZE value for --min-size and --max-size to
allow easy entry of multiples of 1000 (instead of just multiples of 1024)
and off-by-one values too (e.g. --max-size=8mb-1).
- Added the --8-bit-output (-8) option, which tells rsync to avoid escaping
high-bit characters that it thinks are unreadable in the current locale.
- The new option --human-readable (-h) changes the output of --progress,
--stats, and the end-of-run summary to be easier to read. If repeated,
the units become powers of 1024 instead of powers of 1000. (The old
meaning of -h, as a shorthand for --help, still works as long as you
just use it on its own, as in "rsync -h".)
- If lutimes() and/or lchmod() are around, use them to allow the
preservation of attributes on symlinks.
- The --link-dest option now affects symlinks and devices (when possible).
- Added two config items to the rsyncd.conf parsing: "pre-xfer exec" and
"post-xfer exec". These allow a command to be specified on a per-module
basis that will be run before and/or after a daemon-mode transfer. (See
the man page for a list of the environment variables that are set with
information about the transfer.)
- When using the --relative option, you can now insert a dot dir in
the source path to indicate where the replication of the source dirs
should start. For example, if you specify a source path of
rsync://host/module/foo/bar/./baz/dir with -R, rsync will now only
replicate the "baz/dir" part of the source path (note: a trailing
dot dir is unaffected unless it also has a trailing slash).
- Added some new --no-FOO options that make it easier to override unwanted
implied or default options. For example, "-a --no-o" (aka "--archive
--no-owner") can be used to turn off the preservation of file ownership
that is implied by -a.
- Added the --chmod=MODE option that allows the destination permissions to
be changed from the source permissions. E.g. --chmod=g+w,o-rwx
- Added the "incoming chmod" and "outgoing chmod" daemon options that allow
a module to specify what permissions changes should be applied to all
files copied to and from the daemon.
- Allow the --temp-dir option to be specified when starting a daemon, which
sets the default temporary directory for incoming files.
- If --delete is combined with --dirs without --recursive, rsync will now
delete in any directory whose content is being synchronized.
- If --backup is combined with --delete without --backup-dir (and without
--delete-excluded), we add a "protect" filter-rule to ensure that files
with the backup suffix are not deleted.
- The file-count stats that are output by --progress were improved to
better indicate what the numbers mean. For instance, the output:
"(xfer#5, to-check=8383/9999)" indicates that this was the fifth file
to be transferred, and we still need to check 8383 more files out of
a total of 9999.
- The include/exclude code now allows a dir/*** directive (with 3 trailing
stars) to match both the dir itself as well as all the content below the
dir (dir/** would not match the dir).
- Added the --prune-empty-dirs (-m) option that makes the receiving rsync
discard empty chains of directories from the file-list. This makes it
easier to selectively copy files from a source hierarchy and end up with
just the directories needed to hold the resulting files.
- If the --itemize-changes (-i) option is repeated, rsync now includes
unchanged files in the itemized output (similar to -vv, but without all
the other verbose messages that can get in the way). Of course, the
client must be version 2.6.7 for this to work, but the remote rsync only
needs to be 2.6.7 if you're pushing files.
- Added the --specials option to tell rsync to copy non-device special
files (which rsync now attempts even as a normal user). The --devices
option now requests the copying of just devices (character and block).
The -D option still requests both (e.g. --devices and --specials), -a
still implies -D, and non-root users still get a silent downgrade that
omits device copying.
- Added the --super option to make the receiver always attempt super-user
activities. This is useful for systems that allow things such as devices
to be created or ownership to be set without being UID 0, and is also
useful for someone who wants to ensure that errors will be output if the
receiving rsync isn't being run as root.
- Added the --sockopts option for those few who want to customize the TCP
options used to contact a daemon rsync.
- Added a way for the --temp-dir option to be combined with a partial-dir
setting that lets rsync avoid non-atomic updates (for those times when
--temp-dir is not being used because space is tight).
- A new support script, files-to-excludes, will transform a list of files
into a set of include/exclude directives that will copy those files.
- A new option, --executability (-E) can be used to preserve just the
execute bit on files, for those times when using the --perms option is
not desired.
- The daemon now logs each connection and also each module-list request
that it receives.
- New log-format options: %M (modtime), %U (uid), %G (gid), and %B
(permission bits, e.g. "rwxr-xrwt").
- The --dry-run option no longer forces the enabling of --verbose.
- The --remove-sent-files option now does a better job of incrementally
removing the sent files on the sending side (older versions tended to
clump up all the removals at the end).
- A daemon now supersedes its minimal SIGCHLD handler with the standard
PID-remembering version after forking. This ensures that the generator
can get the child-exit status from the receiver.
- Use of the --bwlimit option no longer interferes with the remote rsync
sending error messages about invalid/refused options.
- Rsync no longer returns a usage error when used with one local source arg
and no destination: this now implies the --list-only option, just like
the comparable situation with a remote source arg.
- Added the --copy-dirlinks option, a more limited version of --copy-links.
- Various documentation improvements, including: a better synopsis, some
improved examples, a better discussion of the presence and absence of
--perms (including how it interacts with the new --executability and
--chmod options), an extended discussion of --temp-dir, an improved
discussion of --partial-dir, a better description of rsync's pattern
matching characters, an improved --no-implied-dirs section, and the
documenting of what the --stats option outputs.
- Various new and updated diffs in the patches dir, including: acls.diff,
xattrs.diff, atimes.diff, detect-renamed.diff, and slp.diff.
NEWS for rsync 2.6.6 (28 Jul 2005)
Protocol: 29 (unchanged)
Changes since 2.6.5:
SECURITY FIXES:
- The zlib code was upgraded to version 1.2.3 in order to make it more
secure. While the widely-publicized security problem in zlib 1.2.2 did
not affect rsync, another security problem surfaced that affects rsync's
zlib 1.1.4.
BUG FIXES:
- The setting of flist->high in clean_flist() was wrong for an empty list.
This could cause flist_find() to crash in certain rare circumstances
(e.g. if just the right directory setup was around when --fuzzy was
combined with --link-dest).
- The outputting of hard-linked files when verbosity was > 1 was not right:
without -i it would output the name of each hard-linked file as though
it had been changed (it now outputs a "is hard linked" message for the
file); with -i it would output all dots for the unchanged attributes of
a hard-link (it now changes those dots to spaces, as is done for other
totally unchanged items).
- When backing up a changed symlink or device, get rid of any old backup
item so that we don't get an "already exists" error.
- A couple places that were comparing a local and a remote modification-
time were not honoring the --modify-window option.
- Fixed a bug where the 'p' (permissions) itemized-changes flag might get
set too often (if some non-significant mode bits differed).
- Fixed a really old, minor bug that could cause rsync to warn about being
unable to mkdir() a path that ends in "/." because it just created the
directory (required --relative, --no-implied-dirs, a source path that
ended in either a trailing slash or a trailing "/.", and a non-existing
destination dir to tickle the bug in a recent version).
ENHANCEMENTS:
- Made the "max verbosity" setting in the rsyncd.conf file settable on a
per-module basis (which now matches the documentation).
- The support/rrsync script has been upgraded to verify the args of options
that take args (instead of rejecting any such options). The script was
also changed to try to be more secure and to fix a problem in the parsing
of a pull operation that has multiple sources.
- Improved the documentation that explains the difference between a
normal daemon transfer and a daemon-over remote-shell transfer.
- Some of the diffs supplied in the patches dir were fixed and/or
improved.
BUILD CHANGES:
- Made configure define NOBODY_USER (currently hard-wired to "nobody") and
NOBODY_GROUP (set to either "nobody" or "nogroup" depending on what we
find in the /etc/group file).
- Added a test to the test suite, itemized.test, that tests the output of
-i (log-format w/%i) and some double-verbose messages.
OUTPUT CHANGES:
- Non-printable chars in filenames are now output using backslash-
escaped characters rather than '?'s. Any non-printable character is
output using 3 digits of octal (e.g. "\n" -> "\012"), and a backslash
is now output as "\\". Rsync also uses your locale setting, which
can make it treat fewer high-bit characters as non-printable.
- If rsync received an empty file-list when pulling files, it would
output a "nothing to do" message and exit with a 0 (success) exit
status, even if the remote rsync returned an error (it did not do
this under the same conditions when pushing files). This was changed
to make the pulling behavior the same as the pushing behavior: we
now do the normal end-of-run outputting (depending on options) and
exit with the appropriate exit status.
BUG FIXES:
- A crash bug was fixed when a daemon had its "path" set to "/", did
not have chroot enabled, and used some anchored excludes in the
rsyncd.conf file.
- Fixed a bug in the transfer of a single file when -H is specified
(rsync would either infinite loop or perhaps crash).
- Fixed a case where the generator might try (and fail) to tweak the
write-permissions of a read-only directory in list-only mode (this
only caused an annoying warning message).
- If --compare-dest or --link-dest uses a locally-copied file as the
basis for an updated version, log this better when --verbose or -i
is in effect.
- Fixed the accidental disabling of --backup during the --delete-after
processing.
- Restored the ability to use the --address option in client mode (in
addition to its use in daemon mode).
- Make sure that some temporary progress information from the delete
processing does not get left on the screen when it is followed by a
newline.
- When --existing skips a directory with extra verbosity, refer to it
as a "directory", not a "file".
- When transferring a single file to a different-named file, any
generator messages that are source-file related no longer refer to
the file by the destination filename.
- Fixed a bug where hard-linking a group of files might fail if the
generator hasn't created a needed destination directory yet.
- Fixed a bug where a hard-linked group of files that is newly-linked
to a file in a --link-dest dir doesn't link the files from the rest
of the cluster.
- When deleting files with the --one-file-system (-x) option set, rsync
no longer tries to remove files from inside a mount-point on the
receiving side. Also, we don't complain about being unable to remove
the mount-point dir.
- Fixed a compatibility problem when using --cvs-ignore (-C) and
sending files to an older rsync without using --delete.
- Make sure that a "- !" or "+ !" include/exclude pattern does not
trigger the list-clearing action that is reserved for "!".
- Avoid a timeout in the generator when the sender/receiver aren't
handling the generator's checksum output quickly enough.
- Fixed the omission of some directories in the delete processing when
--relative (-R) was combined with a source path that had a trailing
slash.
- Fixed a case where rsync would erroneously delete some files and then
re-transfer them when the options --relative (-R) and --recursive
(-r) were both enabled (along with --delete) and a source path had a
trailing slash.
- Make sure that --max-size doesn't affect a device or a symlink.
- Make sure that a system with a really small MAXPATHLEN does not cause
the buffers in readfd_unbuffered() to be too small to receive normal
messages. (This mainly affected Cygwin.)
- If a source pathname ends with a filename of "..", treat it as if
"../" had been specified (so that we don't copy files to the parent
dir of the destination).
- If --delete is combined with a file-listing rsync command (i.e. no
transfer is happening), avoid outputting a warning that we couldn't
delete anything.
- If --stats is specified with --delete-after, ensure that all the
"deleting" messages are output before the statistics.
- Improved one "if" in the deletion code that was only checking errno
for ENOTEMPTY when it should have also been checking for EEXIST (for
compatibility with OS variations).
ENHANCEMENTS:
- Added the --only-write-batch=FILE option that may be used (instead
of --write-batch=FILE) to create a batch file without doing any
actual updating of the destination. This allows you to divert all
the file-updating data away from a slow data link (as long as you
are pushing the data to the remote server when creating the batch).
- When the generator is taking a long time to fill up its output buffer
(e.g. if the transferred files are few, small, or missing), it now
periodically flushes the output buffer so that the sender/receiver
can get started on the files sooner rather than later.
- Improved the keep-alive code to handle a long silence between the
sender and the receiver that can occur when the sender is receiving
the checksum data for a large file.
- Improved the auth-errors that are logged by the daemon to include
some information on why the authorization failed: wrong user,
password mismatch, etc. (The client-visible message is unchanged!)
- Improved the client's handling of an "@ERROR" from a daemon so that
it does not complain about an unexpectedly closed socket (since we
really did expect the socket to close).
- If the daemon can't open the log-file specified in rsyncd.conf, fall
back to using syslog and log an appropriate warning. This is better
than what was typically a totally silent (and fatal) failure (since a
daemon is not usually run with the --no-detach option that was
necessary to see the error on stderr).
- The man pages now consistently refer to an rsync daemon as a "daemon"
instead of a "server" (to distinguish it from the server process in a
non-daemon transfer).
- Made a small change to the rrsync script (restricted rsync -- in the
support dir) to make a read-only server reject all --remove-* options
when sending files (to future-proof it against the possibility of
other similar options being added at some point).
OUTPUT CHANGES:
- When rsync deletes a directory and outputs a verbose message about
it, it now appends a trailing slash to the name instead of (only
sometimes) outputting a preceding "directory " string.
- The --stats output will contain file-list time-statistics if both
sides are 2.6.4, or if the local side is 2.6.4 and the files are
being pushed (since the stats come from the sending side).
(Requires protocol 29 for a pull.)
- The "%o" (operation) log-format escape now has a third value (besides
"send" and "recv"): "del." (with trailing dot to make it 4 chars).
This changes the way deletions are logged in the daemon's log file.
- When the --log-format option is combined with --verbose, rsync now
avoids outputting the name of the file twice in most circumstances.
As long as the --log-format item does not refer to any post-transfer
items (such as %b or %c), the --log-format message is output prior to
the transfer, so --verbose is now the equivalent of a --log-format of
'%n%L' (which outputs the name and any link info). If the log output
must occur after the transfer to be complete, the only time the name
is also output prior to the transfer is when --progress was specified
(so that the name will precede the progress stats, and the full
--log-format output will come after).
BUG FIXES:
- Restore the list-clearing behavior of "!" in a .cvsignore file (2.6.3
was only treating it as a special token in an rsync include/exclude
file).
- The combination of --verbose and --dry-run now mentions the full list
of changes that would be output without --dry-run.
- Avoid a mkdir warning when removing a directory in the destination
that already exists in the --backup-dir.
- An OS that has a binary mode for its files (such as cygwin) needed
setmode(fd, O_BINARY) called on the temp-file we opened with
mkstemp(). (Fix derived from the cygwin's 2.6.3 rsync package.)
- Fixed a potential hang when verbosity is high, the client side is
the sender, and the file-list is large.
- Fixed a potential protocol-corrupting bug where the generator could
merge a message from the receiver into the middle of a multiplexed
packet of data if only part of that data had been written out to the
socket when the message from the generator arrived.
- We now check if the OS doesn't support using mknod() for creating
FIFOs and sockets, and compile-in some compatibility code using
mkfifo() and socket() when necessary.
- Fixed an off-by-one error in the handling of --max-delete=N. Also,
if the --max-delete limit is exceeded during a run, we now output a
warning about this at the end of the run and exit with a new error
code (25).
- One place in the code wasn't checking if fork() failed.
- The "ignore nonreadable" daemon parameter used to erroneously affect
readable symlinks that pointed to a non-existent file.
- If the OS does not have lchown() and a chown() of a symlink will
affect the referent of a symlink (as it should), we no longer try
to set the user and group of a symlink.
- The generator now properly runs the hard-link loop and the dir-time
rewriting loop after we're sure that the redo phase is complete.
- When --backup was specified with --partial-dir=DIR, where DIR is a
relative path, the backup code was erroneously trying to backup a
file that was put into the partial-dir.
- If a file gets resent in a single transfer and the --backup option is
enabled along with --inplace, rsync no longer performs a duplicate
backup (it used to overwrite the first backup with the failed file).
- One call to flush_write_file() was not being checked for an error.
- The --no-relative option was not being sent from the client to a
server sender.
- If an rsync daemon specified "dont compress = ..." for a file and the
client tried to specify --compress, the libz code was not handling a
compression level of 0 properly. This could cause a transfer failure
if the block-size for a file was large enough (e.g. rsync might have
exited with an error for large files).
- Fixed a bug that would sometimes surface when using --compress and
sending a file with a block-size larger than 64K (either manually
specified, or computed due to the file being really large). Prior
versions of rsync would sometimes fail to decompress the data
properly, and thus the transferred file would fail its verification.
- If a daemon can't open the specified log file (i.e. syslog is not
being used), die without crashing. We also output an error about
the failure on stderr (which will only be seen if --no-detach was
specified) and exit with a new error code (6).
- A local transfer no longer duplicates all its include/exclude options
(since the forked process already has a copy of the exclude list,
there's no need to send them a set of duplicates).
- When --progress is specified, the output of items that the generator
is creating (e.g. dirs, symlinks) is now integrated into the progress
output without overlapping it. (Requires protocol 29.)
- When --timeout is specified, lulls that occur in the transfer while
the generator is doing work that does not generate socket traffic
(looking for changed files, deleting files, doing directory-time
touch-ups, etc.) will cause a new keep-alive packet to be sent that
should keep the transfer going as long as the generator continues to
make progress. (Requires protocol 29.)
- The stat size of a device is not added to the total file size of the
items in the transfer (the size might be undefined on some OSes).
- Fixed a problem with refused-option messages sometimes not making it
back to the client side when a remote --files-from was in effect and
the daemon was the receiver.
- The --compare-dest option was not updating a file that differred in
(the preserved) attributes from the version in the compare-dest DIR.
- When rsync is copying files into a write-protected directory, fixed
the change-report output for the directory so that we don't report
an identical directory as changed.
ENHANCEMENTS:
- Rsync now supports popt's option aliases, which means that you can
use /etc/popt and/or ~/.popt to create your own option aliases.
- Added the --delete-during (--del) option which will delete files
from the receiving side incrementally as each directory in the
transfer is being processed. This makes it more efficient than the
default, before-the-transfer behavior, which is now also available as
--delete-before (and is still the default --delete-WHEN option that
will be chosen if --delete or --delete-excluded is specified without
a --delete-WHEN choice). All the --del* options infer --delete, so
an rsync daemon that refuses "delete" will still refuse to allow any
file-deleting options (including the new --remove-sent-files option).
- All the --delete-WHEN options are now more memory efficient:
Previously an duplicate set of file-list objects was created on the
receiving side for the entire destination hierarchy. The new
algorithm only creates one directory of objects at a time (for files
inside the transfer).
- Added the --copy-dest option, which works like --link-dest except
that it locally copies identical files instead of hard-linking them.
- Added support for specifying multiple --compare-dest, --copy-dest, or
--link-dest options, but only of a single type. (Promoted from the
patches dir and enhanced.) (Requires protocol 29.)
- Added the --max-size option. (Promoted from the patches dir.)
- The daemon-mode options are now separated from the normal rsync
options so that they can't be mixed together. This makes it
impossible to start a daemon that has improper default option values
(which could cause problems when a client connects, such as hanging
or crashing).
- The --bwlimit option may now be used in combination with --daemon
to specify both a default value for the daemon side and a value
that cannot be exceeded by a user-specified --bwlimit option.
- Added the "port" parameter to the rsyncd.conf file. (Promoted from
the patches dir.) Also added "address". The command-line options
take precedence over a config-file option, as expected.
- In _exit_cleanup(): when we are exiting with a partially-received
file, we now flush any data in the write-cache before closing the
partial file.
- The --inplace support was enhanced to work with --compare-dest,
--link-dest, and (the new) --copy-dest options. (Requires protocol
29.)
- Added the --dirs (-d) option for an easier way to copy directories
without recursion.
- Added the --list-only option, which is mainly a way for the client to
put the server into listing mode without needing to resort to any
internal option kluges (e.g. the age-old use of "-r --exclude="/*/*"
for a non-recursive listing). This option is used automatically
(behind the scenes) when a modern rsync speaks to a modern daemon,
but may also be specified manually if you want to force the use of
the --list-only option over a remote-shell connection.
- Added the --omit-dir-times (-O) option, which will avoid updating
the modified time for directories when --times was specified. This
option will avoid an extra pass through the file-list at the end of
the transfer (to tweak all the directory times), which may provide
an appreciable speedup for a really large transfer. (Promoted from
the patches dir.)
- Added the --filter (-f) option and its helper option, -F. Filter
rules are an extension to the existing include/exclude handling
that also supports nested filter files as well as per-directory
filter files (like .cvsignore, but with full filter-rule parsing).
This new option was chosen in order to ensure that all existing
include/exclude processing remained 100% compatible with older
versions. Protocol 29 is needed for full filter-rule support, but
backward-compatible rules work with earlier protocol versions.
(Promoted from the patches dir and enhanced.)
- Added the --delay-updates option that puts all updated files into
a temporary directory (by default ".~tmp~", but settable via the
--partial-dir=DIR option) until the end of the transfer. This
makes the updates a little more atomic for a large transfer.
- If rsync is put into the background, any output from --progress is
reduced.
- Documented the "max verbosity" setting for rsyncd.conf. (This
setting was added a couple releases ago, but left undocumented.)
- The sender and the generator now double-check the file-list index
they are given, and refuse to try to do a file transfer on a
non-file index (since that would indicate that something had gone
very wrong).
- Added the --itemize-changes (-i) option, which is a way to output a
more detailed list of what files changed and in what way. The effect
is the same as specifying a --log-format of "%i %n%L" (see both the
rsync and rsyncd.conf manpages). Works with --dry-run too.
- Added the --fuzzy (-y) option, which attempts to find a basis file
for a file that is being created from scratch. The current algorithm
only looks in the destination directory for the created file, but it
does attempt to find a match based on size/mod-time (in case the file
was renamed with no other changes) as well as based on a fuzzy
name-matching algorithm. This option requires protocol 29 because it
needs the new file-sorting order. (Promoted from patches dir and
enhanced.) (Requires protocol 29.)
- Added the --remove-sent-files option, which lets you move files
between systems.
- The hostname in HOST:PATH or HOST::PATH may now be an IPv6 literal
enclosed in '[' and ']' (e.g. "[::1]"). (We already allowed IPv6
literals in the rsync://HOST:PORT/PATH format.)
- When rsync recurses to build the file list, it no longer keeps open
one or more directory handles from the dir's parent dirs.
- When building under windows, the default for --daemon is now to
avoid detaching, requiring the new --detach option to force rsync
to detach.
- The --dry-run option can now be combined with either --write-batch or
--read-batch, allowing you to run a do-nothing test command to see
what would happen without --dry-run.
- The daemon's "read only" config item now sets an internal read_only
variable that makes extra sure that no write/delete calls on the
read-only side can succeed.
- The log-format % escapes can now have a numeric field width in
between the % and the escape letter (e.g. "%-40n %08p").
- Improved the option descriptions in the --help text.
BUILD CHANGES:
- Handle an operating system that use mkdev() in place of makedev().
- Improved configure to better handle cross-compiling.
Protocol: 28 (unchanged)
Changes since 2.6.2:
SECURITY FIXES:
- A bug in the sanitize_path routine (which affects a non-chrooted
rsync daemon) could allow a user to craft a pathname that would get
transformed into an absolute path for certain options (but not for
file-transfer names). If you're running an rsync daemon with chroot
disabled, *please upgrade*, ESPECIALLY if the user privs you run
rsync under is anything above "nobody".
OUTPUT CHANGES (ATTN: those using a script to parse the verbose output):
- Please note that the 2-line footer (output when verbose) now uses the
term "sent" instead of "wrote" and "received" instead of "read". If
you are not parsing the numeric values out of this footer, a script
would be better off using the empty line prior to the footer as the
indicator that the verbose output is over.
- The output from the --stats option was similarly affected to change
"written" to "sent" and "read" to "received".
- Rsync ensures that a filename that contains a newline gets mentioned
with each newline transformed into a question mark (which prevents a
filename from causing an empty line to be output).
- The "backed up ..." message that is output when at least 2 --verbose
options are specified is now the same both with and without the
--backup-dir option.
BUG FIXES:
- Fixed a crash bug that might appear when --delete was used and
multiple source directories were specified.
- Fixed a 32-bit truncation of the file length when generating the
checksums.
- The --backup code no longer attempts to create some directories
over and over again (generating warnings along the way).
- Fixed a bug in the reading of the secrets file (by the daemon) and
the password file (by the client): the files no longer need to be
terminated by a newline for their content to be read in.
- If a file has a read error on the sending side or the reconstructed
data doesn't match the expected checksum (perhaps due to the basis
file changing during the transfer), the receiver will no longer
retain the resulting file unless the --partial option was specified.
(Note: for the read-error detection to work, neither side can be
older than 2.6.3 -- older receivers will always retain the file, and
older senders don't tell the receiver that the file had a read
error.)
- If a file gets resent in a single transfer and the --backup option
is enabled, rsync no longer performs a duplicate backup (it used to
overwrite the original file in the backup area).
- Files specified in the daemon's "exclude" or "exclude from" config
items are now excluded from being uploaded (assuming that the module
allows uploading at all) in addition to the old download exclusion.
- Got rid of a potential hang in the receiver when near the end of a
phase.
- When using --backup without a --backup-dir, rsync no longer preserves
the modify time on directories. This avoids confusing NFS.
- When --copy-links (-L) is specified, we now output a separate error
for a symlink that has no referent instead of claiming that a file
"vanished".
- The --copy-links (-L) option no longer has the side-effect of telling
the receiving side to follow symlinks. See the --keep-dirlinks
option (mentioned below) for a way to specify that behavior.
- Error messages from the daemon server's option-parsing (such as
refused options) are now successfully transferred back to the client
(the server used to fail to send the message because the socket
wasn't in the right state for the message to get through).
- Most transfer errors that occur during a daemon transfer are now
returned to the user in addition to being logged (some messages are
intended to be daemon-only and are not affected by this).
- Fixed a bug in the daemon authentication code when using one of the
batch-processing options.
- We try to work around some buggy IPv6 implementations that fail to
implement IPV6_V6ONLY. This should fix the "address in use" error
that some daemons get when running on an OS with a buggy IPv6
implementation. Also, if the new code gets this error, we might
suggest that the user specify --ipv4 or --ipv6 (if we think it will
help).
- When the remote rsync dies, make a better effort to recover any error
messages it may have sent before dying (the local rsync used to just
die with a socket-write error).
- When using --delete and a --backup-dir that contains files that are
hard-linked to their destination equivalents, rsync now makes sure
that removed files really get removed (avoids a really weird rename()
behavior).
- Avoid a bogus run-time complaint about a lack of 64-bit integers when
the int64 type is defined as an off_t and it actually has 64-bits.
- Added a configure check for open64() without mkstemp64() so that we
can avoid using mkstemp() when such a combination is encountered.
This bypasses a problem writing out large temp files on OSes such as
AIX and HP-UX.
- Fixed an age-old crash problem with --read-batch on a local copy
(rsync was improperly assuming --whole-file for the local copy).
- When --dry-run (-n) is used and the destination directory does not
exist, rsync now produces a correct report of files that would be
sent instead of dying with a chdir() error.
- Fixed a bug that could cause a slow-to-connect rsync daemon to die
with an error instead of waiting for the connection to finish.
- Fixed an ssh interaction that could cause output to be lost when the
user chose to combine the output of rsync's stdout and stderr (e.g.
using the "2>&1").
ENHANCEMENTS:
- Added the --partial-dir=DIR option that lets you specify where to
(temporarily) put a partially transferred file (instead of over-
writing the destination file). E.g. --partial-dir=.rsync-partial
Also added support for the RSYNC_PARTIAL_DIR environment variable
that, when found, transforms a regular --partial option (such as
the convenient -P option) into one that also specifies a directory.
- Added --keep-dirlinks (-K), which allows you to symlink a directory
onto another partition on the receiving side and have rsync treat it
as matching a normal directory from the sender.
- Added the --inplace option that tells rsync to write each destination
file without using a temporary file. The matching of existing data
in the destination file can be severely limited by this, but there
are also cases where this is more efficient (such as appending data).
Use only when needed (see the man page for more details).
- Added the "write only" option for the daemon's config file.
- Added long-option names for -4 and -6 (namely --ipv4 and --ipv6)
and documented all these options in the man page.
- Improved the handling of the --bwlimit option so that it's less
bursty, more accurate, and works properly over a larger range of
values.
- The rsync daemon-over-ssh code now looks for SSH_CONNECTION and
SSH2_CLIENT in addition to SSH_CLIENT to figure out the IP address.
- Added the --checksum-seed=N option for advanced users.
- Batch writing/reading has a brand-new implementation that is simpler,
fixes a few weird problems with the old code (such as no longer
sprinkling the batch files into different dirs or even onto different
systems), and is much less intrusive into the code (making it easier
to maintain for the future). The new code generates just one data
file instead of three, which makes it possible to read the batch on
stdin via a remote shell. Also, the old requirement of forcing the
same fixed checksum-seed for all batch processing has been removed.
- If an rsync daemon has a module set with "list = no" (which hides its
presence in the list of available modules), a user that fails to
authenticate gets the same "unknown module" error that they would get
if the module were actually unknown (while still logging the real
error to the daemon's log file). This prevents fishing for module
names.
- The daemon's "refuse options" config item now allows you to match
option names using wildcards and/or the single-letter option names.
- Each transferred file now gets its permissions and modified-time
updated before the temp-file gets moved into place. Previously, the
finished file would have a very brief window where its permissions
disallowed all group and world access.
- Added the ability to parse a literal IPv6 address in an "rsync:" URL
(e.g. rsync://[2001:638:500:101::21]:873/module/dir).
- The daemon's wildcard expanding code can now handle more than 1000
filenames (it's now limited by memory instead of having a hard-wired
limit).
INTERNAL:
- Some cleanup in the exclude code has saved some per-exclude memory
and made the code easier to maintain.
- Improved the argv-overflow checking for a remote command that has a
lot of args.
- Use rsyserr() in the various places that were still calling rprintf()
with strerror() as an arg.
- If an rsync daemon is listening on multiple sockets (to handle both
IPv4 and IPv6 to a single port), we now close all the unneeded file
handles after we accept a connection (we used to close just one of
them).
- Optimized the handling of larger block sizes (rsync used to slow to a
crawl if the block size got too large).
- Optimized away a loop in hash_search().
- Some improvements to the sanitize_path() and clean_fname() functions
makes them more efficient and produce better results (while still
being compatible with the file-name cleaning that gets done on both
sides when sending the file-list).
- Got rid of alloc_sanitize_path() after adding a destination-buffer
arg to sanitize_path() made it possible to put all the former's
functionality into the latter.
- The file-list that is output when at least 4 verbose options are
specified reports the uid value on the sender even when rsync is
not running as root (since we might be sending to a root receiver).
BUILD CHANGES:
- Added a "gen" target to rebuild most of the generated files,
including configure, config.h.in, the man pages, and proto.h.
- If "make proto" doesn't find some changes in the prototypes, the
proto.h file is left untouched (its time-stamp used to always be
updated).
- The variable $STRIP (that is optionally set by the install-strip
target's rule) was changed to $INSTALL_STRIP because some systems
have $STRIP already set in the environment.
- Fixed a build problem when SUPPORT_HARD_LINKS isn't defined.
- When cross-compiling, the gettimeofday() function is now assumed to
be a modern version that takes two-args (since we can't test it).
DEVELOPER RELATED:
- The scripts in the testsuite dir were cleaned up a bit and a few
new tests added.
- Some new diffs were added to the patches dir, and some accepted
ones were removed.
- Fixed a major bug in the sorting of the filenames when --relative
is used for some sources (probably just "/", but don't depend on
that). This fix ensures that we ask for the right file-list item
when requesting changes from the sender.
- Rsync now checks the return value of the close() function to
better report disk-full problems on an NFS file system.
- Paths sent to an rsync daemon are more thoroughly sanitized when
chroot is not used. If you're running a non-read-only rsync
daemon with chroot disabled, *please upgrade*, ESPECIALLY if the
user privs you run rsync under is anything above "nobody".
- Lower memory use, more optimal transfer of data over the socket,
and lower CPU usage (see the INTERNAL section for details).
- The RSYNC_PROXY environment variable can now contain a
"USER:PASS@" prefix before the "HOST:PORT" information.
(Bardur Arantsson)
- The --progress output now mentions how far along in the transfer
we are, including both a count of files transferred and a
percentage of the total file-count that we've processed. It also
shows better current-rate-of-transfer and remaining-transfer-time
values.
- The configure script now accepts --with-rsyncd-conf=PATH to
override the default value of the /etc/rsyncd.conf file.
- Added a couple extra diffs in the "patches" dir, removed the ones
that got applied, and rebuilt the rest.
- Documentation changes now attempt to describe some often mis-
understood features more clearly.
- When -x (--one-file-system) is combined with -L (--copy-links) or
--copy-unsafe-links, no symlinked files are skipped, even if the
referent file is on a different filesystem.
- The --link-dest code now works properly for a non-root user when
(1) the UIDs of the source and destination differ and -o was
specified, or (2) when the group of the source can't be used on
the destination and -g was specified.
- Fixed a bug in the handling of -H (hard-links) that might cause
the expanded PATH/NAME value of the current item to get
overwritten (due to an expanded-name caching bug).
- We now reset the "new data has been sent" flag at the start of
each file we send. This makes sure that an interrupted transfer
with the --partial option set doesn't keep a shorter temp file
than the current basis file when no new data has been transfered
over the wire for that file.
- Fixed a byte-order problem in --batch-mode on big-endian machines.
(Jay Fenlason)
- Fixed configure bug when running "./configure --disable-ipv6".
- Fixed "make test" bug when build dir is not the source dir.
- When using --cvs-exclude, the exclude items we get from a
per-directory's .cvsignore file once again only affect that one
directory (not all following directories too). The items are also
now properly word-split and parsed without any +/- prefix parsing.
- When specifying the USER@HOST: prefix for a file, the USER part
can now contain an '@', if needed (i.e. the last '@' is used to
find the HOST, not the first).
- Fixed some bugs in the handling of group IDs for non-root users:
(1) It properly handles a group that the sender didn't have a name
for (it would previously skip changing the group on any files in
that group). (2) If --numeric-ids is used, rsync no longer
attempts to set groups that the user doesn't have the permission
to set.
- Fixed the "refuse options" setting in the rsyncd.conf file.
- Improved the -x (--one-file-system) flag's handling of any mount-
point directories we encounter. It is both more optimal (in that
it no longer does a useless scan of the contents of the mount-
point dirs) and also fixes a bug where a remapped mount of the
original filesystem could get discovered in a subdir we should be
ignoring.
- Rsync no longer discards a double-slash at the start of a filename
when trying to open the file. It also no longer constructs names
that start with a double slash (unless the user supplied them).
- Path-specifying options to a daemon should now work the same with
or without chroot turned on. Previously, such a option (such as
--link-dest) would get its absolute path munged into a relative
one if chroot was not on, making that setting fairly useless.
Rsync now transforms the path into one that is based on the
module's base dir when chroot is not enabled.
- Fixed compilation problem on Tru64 Unix (having to do with
sockaddr.sa_len and sockaddr.sin_len).
- Fixed a compatibility problem interacting with older rsync
versions that might send us an empty --suffix value without
telling us that --backup-dir was specified.
- The "hosts allow" option for a daemon-over-remote-shell process
now has improved support for IPv6 addresses and a fix for systems
that have a length field in their socket structs.
- Fixed the ability to request an empty backup --suffix when sending
files to an rsync daemon.
Major changes since 2.5.7:
* "ssh" is now the default remote shell for rsync. If you want to
change this, configure like this: "./configure --with-rsh=rsh".
* Added --files-from, --no-relative, --no-implied-dirs, and --from0.
Note that --from0 affects the line-ending character for all the
files read by the --*-from options. (Wayne Davison)
* Length of csum2 is now per-file starting with protocol version
27. (J.W. Schultz)
* Per-file dynamic block size is now sqrt(file length). The
per-file checksum size is determined according to an algorithm
provided by Donovan Baarda which reduces the probability of rsync
algorithm corrupting data and falling back using the whole md4
checksums. (J.W. Schultz, Donovan Baarda)
* The --stats option no longer includes the (debug) malloc summary
unless the verbose option was specified at least twice.
* Added a new error/warning code for when files vanish from the
sending side. Made vanished source files not interfere with the
file-deletion pass when --delete-after was specified.
* Various trailing-info sections are now preceded by a newline.
* Many bug-fixes.
