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.

Changes:
- follow PKG_SYSCONFDIR
- fix paths in manpages
- minor cleanups
2.5.6:
======
ENHANCEMENTS:
=============
- The --delete-after option now implies --delete. (Wayne Davison)
- The --suffix option can now be used with --backup-dir. (Michael
Zimmerman)
- Combining "::" syntax with the -rsh/-e option now uses the
specified remote-shell as a transport to talk to a (newly-spawned)
server-daemon. This allows someone to use daemon features, such
as modules, over a secure protocol, such as ssh. (JD Paul)
- The rsync:// syntax for daemon connections is now accepted in the
destination field.
- If the file name given to --include-from or --exclude-from is "-",
rsync will read from standard input. (J.W. Schultz)
- New option --link-dest which is like --compare-dest except that
unchanged files are hard-linked in to the destination directory.
(J.W. Schultz)
- Don't report an error if an excluded file disappears during an
rsync run. (Eugene Chupriyanov and Bo Kersey)
- Added .svn to --cvs-exclude list to support subversion. (Jon
Middleton)
- Properly support IPv6 addresses in the rsyncd.conf "hosts allow"
And "hosts deny" fields. (Hideaki Yoshifuji)
- Changed exclude file handling to permit DOS or MAC style line
terminations. (J.W. Schultz)
- Ignore errors from chmod when -p/-a/--preserve-perms is not set.
(Dave Dykstra)
BUG FIXES:
==========
- Fix "forward name lookup failed" errors on AIX 4.3.3. (John
L. Allen, Martin Pool)
- Generate each file's rolling-checksum data as we send it, not
in a separate (memory-eating) pass before hand. This prevents
timeout errors on really large files. (Stefan Nehlsen)
- Fix compilation on Tru64. (Albert Chin, Zoong Pham)
- Better handling of some client-server errors. (Martin Pool)
- Fixed a crash that would occur when sending a list of files that
contains a duplicate name (if it sorts to the end of the file
list) and using --delete. (Wayne Davison)
- Fixed the file-name duplicate-removal code when dealing with multiple
dups in a row. (Wayne Davison)
- Fixed a bug that caused rsync to lose the exit status of its child
processes and sometimes return an exit code of 0 instead of showing
an error. (David R. Staples, Dave Dykstra)
- Fixed bug in --copy-unsafe-links that caused it to be completely
broken. (Dave Dykstra)
- Prevent infinite recursion in cleanup code under certain circumstances.
(Sviatoslav Sviridov and Marc Espie)
- Fixed a bug that prevented rsync from creating intervening directories
when --relative-paths/-R is set. (Craig Barratt)
- Prevent "Connection reset by peer" messages from Cygwin. (Randy O'Meara)
INTERNAL:
=========
- Many code cleanups and improved internal documentation. (Martin
Pool, Nelson Beebe)
- Portability fixes. (Dave Dykstra and Wayne Davison)
- More test cases. (Martin Pool)
- Some test-case fixes. (Brian Poole, Wayne Davison)
- Updated included popt to the latest vendor drop, version 1.6.4.
(Jos Backus)
- Updated config.guess and config.sub to latest versions; this
means rsync should build on more platforms. (Paul Green)
rsync 2.5.5 "Snowy River" (2 April 2002)
ENHANCEMENTS:
* With --progress, when a transfer is complete show the time taken;
otherwise show expected time to complete. (Cameron Simpson)
* Make "make install-strip" works properly, and "make install"
accepts a DESTDIR variable for help in building binary packages.
(Peter Breitenlohner, Greg Louis)
* If configured with --enable-maintainer-mode, then on receipt of
a fatal signal rsync will try to open an xterm running gdb,
similarly to Samba's "panic action" or GNOME's bug-buddy.
(Martin Pool)
BUG FIXES:
* Fix situation where failure to fork (e.g. because out of process
slots) would cause rsync to kill all processes owned by the
current user. Yes, really! (Paul Haas, Martin Pool)
* Fix test suite on Solaris. (Jos Backus, Martin Pool)
* Fix minor memory leak in socket code. (Dave Dykstra, Martin
Pool.)
* Fix --whole-file problem that caused it to be the default even
for remote connections. (Martin Pool, Frank Schulz)
* Work around bug in Mac OS X mkdir(2), which cannot handle
trailing slashes.
<http://www.opensource.apple.com/bugs/X/BSD%20Kernel/2734739.html>
(Martin Pool)
* Improved network error handling. (Greg A. Woods)
- Additional fix for zlib double-free bug. (Martin Pool, Andrew
Tridgell) (CVE CAN-2002-0059)
- Merge in changes from zlib 1.1.3 to zlib 1.1.4. (Jos Backus)
(Note that rsync still uses a custom version of zlib; you can
not just link against a system library. See zlib/README.rsync)
- Additional test cases for --compress. (Martin Pool)
- Make sure that supplementary groups are removed from a server
process after changing uid and gid. (Ethan Benson) (Debian bug
#132272, CVE CAN-2002-0080)
- Fix zlib double-free bug. (Owen Taylor, Mark J Cox) (CVE
CAN-2002-0059)
- Fixed problem that in many cases caused the error message
unexpected read size of 0 in map_ptr
and resulted in the wrong data being copied.
- Fixed compilation errors on some systems caused by the use of
"unsigned int64" in rsync.h.
- Fixed problem on systems such as Sunos4 that do not support realloc
on a NULL pointer; error was "out of memory in flist_expand".
- Fix for rsync server processes hanging around after the client
unexpectedly disconnects. (Colin Walters) (Debian bug #128632)
- Cope with BSD systems on which mkdir() will not accept a trailing
slash.
- Merge in changes from zlib 1.1.2 to zlib 1.1.3. (Note that
rsync still uses a custom version of zlib; you can not just link
against a system library. See zlib/README.rsync)
- Command to initiate connections is only shown with -vv, rather
than -v as in 2.5.2. Output from plain -v is more similar to
what was historically used so as not to break scripts that try
to parse the output.
- Added --no-whole-file and --no-blocking-io options (Dave Dykstra)
- Made the --write-batch and --read-batch options actually work
and added documentation in the man page (Jos Backus)
- If the daemon is unable to fork a child to accept a connection,
print an error message. (Colin Walters)
rsync 2.5.2 (26 Jan 2002)
SECURITY FIXES:
* Signedness security patch from Sebastian Krahmer
<krahmer@suse.de> -- in some cases we were not sufficiently
careful about reading integers from the network.
BUG FIXES:
* Fix possible string mangling in log files.
* Fix for setting local address of outgoing sockets.
* Better handling of hardlinks and devices on platforms with
64-bit dev_t or ino_t.
* Name resolution on machines supporting IPv6 is improved.
* Fix for device nodes. (dann frazier) (Debian #129135)
ENHANCEMENTS:
* With -v, rsync now shows the command used to initiate an ssh/rsh
connection.
* --statistics now shows memory heap usage on platforms that
support mallinfo().
* "The Ted T'so school of program optimization": make progress
visible and people will think it's faster. (With --progress,
rsync will show you how many files it has seen as it builds the
file_list, giving some indication that it has not hung.)
* Improvements to batch mode support. This is still experimental
but testing would be welcome. (Jos Backus)
* New --ignore-existing option, patch previously distributed with
Vipul's Razor. (Debian #124286)
* native IPv6 support
* bug fixes
* --progress and -P now show estimated data transfer rate
* --no-detach option
* clearer error messages for some conditions
- client does not accept additional argument -[46] (IPv4 or IPv6)
- server SEGV when there's no reverse mapping from IPv[46] address to FQDN
ok'ed on packages@netbsd.org
