If - you are not parsing the numeric values out of this footer, a script - should 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". - - - Made sure that a filename that contains a newline gets mentioned with - each newline transformed into a question mark (which makes sure that - a filename can't span multiple lines nor cause an empty line to be - output). +NEWS for rsync 2.6.4 (UNRELEASED) +Protocol: 29 (changed) +Changes since 2.6.3: - BUG FIXES: - - - Fixed a crash bug that might appear when --delete was used and - multiple source directories were specified. - - - Fixed the 32-bit truncation of the file length when generating the - checksums. + OUTPUT CHANGES: - - The --backup code no longer attempts to create some directories - over and over again (generating warnings along the way). + - 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. - - 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. + - 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). + + BUG FIXES: - - 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.) + - 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). - - If a file gets resent in a single transfer and the --backup option - is enabled, rsync no longer performs a duplicate backup (losing the - original file in the process). + - The --dry-run option (-n) now mentions changes in directories (w/-v). + It also now includes the normal uptodate output information for -vv. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - Avoid a mkdir warning when removing a directory in the destination + that already exists in the --backup-dir. - - 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. + - An OS that has a binary mode for its files (such as cygwin0 needed + setmode(fd, O_BINARY) called on the temp-file we opened with + mkstemp(). (Fix derived from the cygwin's rsync package.) - - Got rid of a potential hang in the receiver when near the end of a - phase. + - Fixed a potential hang when verbosity is high, the client side is + the sender, and the file-list is large. - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - We now check if the OS doesn't support using mknod() for creating + FIFOs and sockets, and compile-in using mkfifo() and socket() when + necessary. - - 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". + - Fixed an off-by-one error in the handling of --max-delete=N. - - 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. + - One place in the code wasn't checking if fork() failed. - - Error messages from the daemon server's option-parsing (such as - refused options) now get sent back to the client (the server used - to just exit because the socket wasn't in the right state to send - the message). + - The "ignore nonreadable" daemon parameter no longer affects symlinks + that are being copied, even if they point nowhere. - - Most 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). + - If the OS does not have lchown() and its chown() tries to set the + referent of a symlink (as it should), we no longer try to set the + user and group of a symlink. - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - 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. - - 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 --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. - - 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). + - One call to flush_write_file() was not being checked for an 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 (works around a really weird - rename() behavior). + - The --no-relative option was not being sent from the client to a + server sender. - - 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. + - 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 (i.e. rsync might have + exited with an error for large files). - - 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. + - If a daemon can't open the specified log file (i.e. syslog is not + being used), die without crashing. We also try to output an error + about the failure (which will only be seen if --no-detach was + specified). 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 - - - 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 via - stdin. Also, the old requirement of using 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. - - - The finished file now gets its permissions and modified-time updated - before it gets movied into place. + - 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 on the receiving side incrementally as each directory in the + transfer is being processed (which makes it more efficient than the + default, before-the-transfer behavior of --delete). Note that the + --del option is implemented as an internally-defined popt alias, so + an rsync daemon that refuses "delete" (which, for safety's sake, + really matches "delete*") will still refuse all delete options. The + default --delete behavior is also explicitly selectable via + --delete-before. + + - All the --delete-WHEN options are now more memory efficient: + Previously an entire duplicate set of file-list objects was created + on the receiving side for the entire destination hierarchy. The new + algorithm only creates a single directory of objects at a time. + + - Added the --copy-dest option, which works like --link-dest except + that it includes copies of identical files. + + - 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.) + + - Added the --max-size option. (Promoted from the patches dir.) + + - The daemon-mode options were separated from the normal rsync options + so that they can't be mixed together. This makes it impossible to + start a daemon that had improper default option values that could + cause problems (such as a hang or an abort) when a client connects. + + - 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". + + - 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. + + - 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 + option kluges (e.g. the age-old use of "-r --exclude="/*/*" for a + non-recursive listing). This option is used automatically 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 can result in + an appreciable speedup for a really large transfer. + + - 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. + + - 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.) + + SUPPORT FILES: + + - Added support/atomic-rsync -- a perl script that will transfer some + files using rsync, and then move the updated files into place all at + once at the end of the transfer. Only works when pulling, and uses + --link-dest and a parallel hierarchy of files to effect its update. + + - Added support/mnt-excl that takes the /proc/mounts file and + translates it into a set of excludes that will exclude all mount + points (even mapped mounts to the same disk). The excludes are made + relative to the specified source dir and properly anchored. + + - Added support/savetransfer.c -- a C program that can make a copy of + all the data that flows over the wire. This lets you test for data + corruption (by saving the data on both the sending side and the + receiving side) or provides a way to help debug a protocol error. + + - Added support/rrsync -- my version of Joe Smith's restricted rsync + perl script. This helps to ensure that only certain rsync commands + can be run by an ssh invocation. + + - Improved the option descriptions in the --help text. INTERNAL: - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - Added better checking of the checksum-header values that come over + the socket. - - Improved the argv-overflow checking for a remote command that has - a lot of args. + - Merged the various delete-file functions into a single function so + that it is easier to maintain. - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + - Improved the type of some variables (particularly blocksize vars) for + consistency and proper size. - - 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). + - Got rid of the uint64 type (which we didn't need). - - Optimized the handling of larger block sizes (rsync used to slow to - a crawl if the block size got too large). Also cap the block size. + - Use a slightly more compatible set of core #include directives. - - Optimized away a loop in hash_search(). + - Defined int32 in a way that ensures that the build dies if we can't + find a variable with at least 32 bits. 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 set in the environment. - - - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. - - DEVELOPER RELATED: - - - The scripts in the testsuite dir were cleaned up a bit. - - - Some new diffs were added to the patches dir, and some accepted - ones were removed. + - Handle an operating system that use mkdev() in place of makedev(). + - Improved configure to better handle cross-compiling.
