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 --max-size option (promoted from the patches dir).
- The daemon-mode options were separated from the normal rsync options
user to start a daemon that had improper default option values that
could cause problems (a hang or an exit) when a client connects.
+ - The --bwlimit option may now be used in combination with --daemon
+ to specify a default value for the daemon side and also a value
+ that cannot be exceeded by a user-specified --bwlimit option.
+
- 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.
BUILD CHANGES:
- Handle an operating system that use mkdev() in place of makedev().

-NEWS for rsync 2.6.3 (30 Sep 2004)
-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.
