This avoids unexpected behavior and should not adversely + affect most people. If you're one of those rare people who relied + upon having an implied dir be duplicated as a symlink, either specify + --keep-dirlinks or --no-implied-dirs. - - 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. + BUG FIXES: - - If a file has a read error on the sending side, the receiver will - no longer keep the resulting file unless the --partial option was - specified. (Note: both sides must be running 2.6.3 for this to - work -- older receivers always keep the file, and older senders - don't tell the receiver that the file was not read correctly.) + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - 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). + - Made the output of all file types consistent when using a --*-dest + option. Prior versions used to output too many creation events for + matching items. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - The code that waits for a child pid now handles being interrupted by a + signal. This fixes a problem with the pre-xfer exec function not being + able to get the exit status from the script. - - 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. + - A negated filter rule (with a '!' modifier) no longer loses the negation + when sending the filter rules to the remote rsync. - - Got rid of a potential hang in the receiver when near the end of a - phase. + - Fixed a problem with the --out-format (aka --log-format) option %f: it + would output superfluous directory information for a non-daemon rsync. - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - Fixed a problem with -vv (double --verbose) and --stats when "pushing" + files (which includes local copies). Version 2.6.9 would complete the + copy, but exit with an error when the receiver output its memory stats. - - 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". + - If --password-file is used on a non-daemon transfer, rsync now complains + and exits. This should help users figure out that they can't use this + option to control a remote shell's password prompt. - - 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). + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. - - 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). + - The itemized output of a newly-created destination directory is now + output as a creation event, not a change event. - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - Improved --hard-link so that more corner cases are handled correctly + when combined with options such as --link-dest and/or --ignore-existing. - - 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). + - The --append option no longer updates a file that has the same size. - ENHANCEMENTS: + - Fixed a bug when combining --backup and --backup-dir with --inplace: + any missing backup directories are now created. - - 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. + - Fixed a bug when using --backup and --inplace with --whole-file or + --read-batch: backup files are actually created now. - - Added the "write only" option to the daemon's config file. + - Starting up an extra copy of an rsync daemon does not delete the pidfile + for the running daemon -- if the pidfile exists, the extra program will + exit with an error. - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. + - The daemon pidfile is checked and created sooner in the startup sequence. - - Improved the handling of the --bwlimit option so that it's less - bursty, more accurate, and works properly over a larger range of - values. + ENHANCEMENTS: - - 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. + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.x version. This starts the transfer going more quickly + (before all the files have been found), and requires much less memory. + See the --recursive option in the manpage for some restrictions. + + - Saved memory in the non-incremental-recursion algorithm for typical + option values (usually saving from 21-29 bytes per file). + + - The default --delete algorithm is now --delete-during when talking to a + 3.x rsync. This is a faster scan than using --delete-before (which is + the default when talking to older rsync versions), and is compatible with + the new incremental recursion mode. + + - Rsync now allows multiple remote-source args to be specified rather than + having to rely on a special space-splitting side-effect of the remote- + shell. Additional remote args must specify the same host or have an + empty hostname, as seen here: :file1 ::module/file2. This means that + local use of brace expansion now works: rsync -av host:path/{f1,f2} . + + - Added the --delete-delay option, which is a more efficient way to delete + files at the end of the transfer without needing a separate delete pass. + + - Added the --acls (-A) option to preserve Access Control Lists. This is + an improved version of the prior patch that was available, and it even + supports OS X ACLs. (If you need to have backward compatibility with + old, patched versions of rsync, apply the acls.diff file from the patches + dir.) + + - Added the --xattrs (-X) option to preserver extended attributes. This is + an improved version of the prior patch that was available. (If you need + to have backward compatibility with old, patched versions of rsync, apply + the xattrs.diff file from the patches dir.) + + - Added the --fake-super option that allows a non-super user to preserve + all attributes of a file by using a special extended-attribute idiom. + There is also an analogous "fake super" option for an rsync daemon. + + - Added the --iconv option, which allows rsync to convert filenames from + one character-set to another during the transfer. The default is to make + this feature available as long as your system has iconv_open(). If + compilation fails, specify --disable-iconv to configure, and then + rebuild. If you want rsync to perform character-set conversions by + default, you can specify --enable-iconv=CONVERT_STRING with the default + value for the --iconv option that you wish to use. For example, + --enable-iconv=. is a good choice. See the rsync manpage for an + explanation of the --iconv option's settings. + + - Added the --skip-compress=LIST option to override of the default list of + file suffixes that will not be compressed when using --compress. + + - The daemon's default for "dont compress" was extended to include: + *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg + The matching routine was also optimized to run more quickly. + + - The --max-delete option now outputs a warning if it skipped any file + deletions, including a count of how many deletions were skipped. (Older + versions just silently stopped deleting things.) + + - You may specify --max-delete=0 to a 3.0.0 client to request that it warn + about extraneous files without deleting anything. If you're not sure + what version the client is, you can use the less-obvious --max-delete=-1, + as both old and new versions will treat that as the same request (though + older versions don't warn). + + - The --hard-link option now uses less memory on both the sending and + receiving side for all protocol versions. For protocol 30, the use of a + hashtable on the sending side allows us to more efficiently convey to the + receiver what files are linked together. This reduces the amount of data + sent over the socket by a considerable margin (rather than adding more + data), and limits the in-memory storage of the device+inode information + to just the sending side for the new protocol 30, or to the receiving + side when speaking an older protocol (note that older rsync versions kept + the device+inode information on both sides). + + - The filter rules now support a perishable ("p") modifier that marks rules + that should not have an effect in a directory that is being deleted. e.g. + -f '-p .svn/' would only affect "live" .svn directories. + + - If we get an error setting the time on a symlink, we don't complain about + it anymore (since some operating systems don't support that, and it's not + that important). + + - Protocol 30 now uses MD5 checksums instead of MD4. + + - If a daemon module's "path" value is not an absolute pathname, the code + now makes it absolute internally (making it work properly). + + - Changed the --append option to not checksum the existing data in the + destination file, which speeds up file appending. + + - Added the --append-verify option, which works like the older --append + option (verifying the existing data in the destination file). For + compatibility with older rsync versions, any use of --append that is + talking protocol 29 or older will revert to the --append-verify method. + + - Documented and extended the support for the RSYNC_CONNECT_PROG variable + that can be used to enhance the client side of a daemon connection. + + - Added the --protect-args (-s) option, that tells rsync to send most of + the command-line args at the start of the transfer rather than as args + to the remote-shell command. This protects them from space-splitting, + and only interprets basic wildcard special shell characters (*?[). + + - Improved the dashes and double-quotes in the nroff manpage output. + + - We now support a lot more --no-OPTION override options. - - Added the --checksum-seed=N option for advanced users. + INTERNAL: - - Batch writing/reading has a brand-new implementation that is - simpler, fixes a few weird problems with the old code, and is much - less intrusive into the code (making it easier to maintain for the - future). (Chris Shoemaker) + - The file-list sorting algorithm now uses a sort that keeps any same- + named items in the same order as they were specified. This allows + rsync to always ensure that the first of the duplicates is the one + that will be included in the copy. The new sort was also faster + than the glibc version of qsort() and mergesort() in my testing. - INTERNAL: + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - Fixed a build problem with older (2.x) versions of gcc. - - Improved the argv-overflow checking for a remote command that has - a lot of args. + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + - Changed strcat/strcpy/sprintf function calls to use safer versions. - - 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). + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - Optimized away a loop in hash_search(). + - Added missing prototypes for compatibility functions from the lib dir. - BUILD CHANGES: + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - - Added a "gen" target to rebuild most of the generated files, - including configure, config.h.in, the man pages, and proto.h. + - Made the sending of some numbers more efficient for protocol 30. - - 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). + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - 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. + - Improved the use of "const" on pointers. - - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. + - Improved J.W.'s pool_alloc routines to add a way of freeing older + sections of a pool's memory. DEVELOPER RELATED: - - The scripts in the testsuite dir were cleaned up a bit. + - Rsync is now licensed under the GPLv3 or later. - - Some new diffs were added to the patches dir, and some accepted - ones were removed. + - When running the tests, we now put our per-test temp dirs into a sub- + directory named testtmp (which is created, if missing). This allows + someone to symlink the testtmp directory to another filesystem (which is + useful if the build dir's filesystem does not support ACLs and xattrs, + and another file system does). + - Rsync now has a way of handling protocol-version changes during the + development of a new protocol version. This exchange of sub-version + info does not interfere with the {MIN,MAX}_PROTOCOL_VERSION checking + in older versions (since we'd quickly exceed the MAX_PROTOCOL_VERSION + if we incremented the main PROTOCOL_VERSION value for every minor + change during development).
