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 itemized output now uses 'S' for a special file instead of + clumping them together with the 'D' for devices. The number of + characters is also different (to remove an unused field). BUG FIXES: - - Fixed a crash bug that might appear when --delete was used and - multiple source directories were specified. + - Fixed a really old bug that caused --checksum (-c) to checksum all the + files encountered during the delete scan (ouch). - - Fixed the 32-bit truncation of the file length when generating the - checksums. + - Made hard-links work with symlinks and devices again. - - The --backup code no longer attempts to create some directories - over and over again (generating warnings along the way). + - If the sender gets an early EOF reading a source file, we propagate this + error to the receiver so that it can discard the file and try requesting + it again (which is the existing behavior for other kinds of read errors). - - 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 device-file/special-file changes permissions, rsync now updates the + permissions without recreating the file. - - 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 the user specifies a remote-host for both the source and destination, + we now output a syntax error rather than trying to open the destination + hostspec as a filename. - - 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). + - When --inplace creates a new destination file, rsync now creates it with + permissions 0600 instead of 0000 -- this makes restarting possible when + the transfer gets interrupted in the middle of sending a new file. - - 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. + - Reject the combination of --inplace and --sparse since the sparse-output + algorithm doesn't work when overwriting existing data. - - Got rid of a potential hang in the receiver when near the end of a - phase. + - Fixed the directory name in the error that is output when pop_dir() + fails. - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - Really fixed the parsing of a "!" entry in .cvsignore files this time. - - 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 the generator gets a stat() error on a file, output it (this used to + require at least -vv for the error to be seen). - - 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. + - If waitpid() fails or the child rsync didn't exit cleanly, we now handle + the exit status properly and generate a better error. - - 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). + - Fixed some glitches in the double-verbose output when using --copy-dest, + --link-dest, or --compare-dest. - - 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). + - Fixed the matching of the dont-compress items (e.g. *.gz) against files + that have a path component containing a slash. - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - If code reading a filter/exclude file an EINTR error, rsync now clears + the error flag on the file handle so it can keep on reading. - - 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). + - If --relative is active, the sending side cleans up trailing "/" or "/." + suffixes to avoid triggering a bug in older rsync versions. Also, we now + reject a ".." dir if it would be sent as a relative 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). + - If a non-directory is in the way of a directory and rsync is run with + --dry-run and --delete, rsync no longer complains about not being able + to opendir() the not-yet present directory. - - 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). + - Got rid of the need for --force to be used in some circumstances with + --delete-after (making it consistent with --delete-before/-during). - - 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. + ENHANCEMENTS: - - 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. + - Added the --specials option to tell rsync to copy special files (and does + not require root). The --devices option now affects just character and + block devices (which now matches the documentation). The -D option still + requests both --devices and --specials, and -a still implies -D. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - Added the --append option that makes rsync append data onto files that + are longer on the source than the destination (this includes new files). - - 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. + - Added the --min-size=SIZE option to exclude small files from the + transfer. - ENHANCEMENTS: + - Added the --compress-level option to allow you to set how aggressive + rsync's compression should be (this option implies --compress). - - 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 + - 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 --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. + - The options --human-readable (-h) and --si change the output of the + --stats and the end-of-run summary to be easier to read. - - 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). + - If lutimes() and/or lchmod() are around, use them to allow the + preservation of attributes on symlinks. - - Added the "write only" option for the daemon's config file. + - The --link-dest option now affects symlinks and devices (when possible). - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. + - Improved the output of hard-linked and copied files when using + --link-dest, --copy-dest, or --compare-dest. - - Improved the handling of the --bwlimit option so that it's less - bursty, more accurate, and works properly over a larger range of - values. + - 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 manpage for a list of the environment variables that are set with + information about the transfer.) - - 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. + - 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 the --checksum-seed=N option for advanced users. + - 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. - - 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 over a remote shell. Also, the old requirement of forcing the - same fixed checksum-seed for all batch processing has been removed. + - Added the --chmod=MODE option that allows the destination permissions to + be changed from the source permissions. E.g. --chmod=g+w,o-rwx - - 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. + - 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. - - The daemon's "refuse options" config item now allows you to match - option names using wildcards and/or the single-letter option names. + - Allow the --temp-dir option to be specified when starting a daemon, which + sets the default temporary directory for incoming files. - - The finished file now gets its permissions and modified-time updated - before it gets moved into place. + - If --delete is combined with --dirs without --recursive, rsync will now + delete in any directory whose content is being synchronized. - - Lots of documentation improvements in the exclude/include sections. + - 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. - INTERNAL: + - 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). - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - 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. - - Improved the argv-overflow checking for a remote command that has a - lot of args. + - 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. - - Use rsyserr() in the various places that were still calling rprintf() - with strerror() as an arg. + - 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. - - 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). + - Added the --sockopts option for those few who want to customize the TCP + options used to contact a daemon rsync. - - Optimized the handling of larger block sizes (rsync used to slow to a - crawl if the block size got too large). + - 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). - - Optimized away a loop in hash_search(). + - Some minor documentation improvements. - - 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). + - Updated some diffs in the patches dir. - - 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. + - 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. - BUILD CHANGES: + INTERNAL: - - Added a "gen" target to rebuild most of the generated files, - including configure, config.h.in, the man pages, and proto.h. + - Some buffer sizes were expanded a bit, particularly on systems where + MAXPATHLEN is overly small (e.g. cygwin). - - 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). + - If io_printf() tries to format more data than fits in the buffer, exit + with an error instead of transmitting a truncated buffer. - - 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. + - If a va_copy macro is defined, lib/snprintf.c will use it when defining + the VA_COPY macro. - - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. + - Reduced the amount of stack memory needed for each level of directory + recursion by nearly MAXPATHLEN bytes. - DEVELOPER RELATED: + - The wildmatch function was extended to allow an array of strings to be + supplied as the string to match. This allows the exclude code to do less + string copying. + + - Got rid of the safe_fname() function (and all the myriad calls) and + replaced it with a new function in the log.c code that filters all the + output going to the terminal. - - The scripts in the testsuite dir were cleaned up a bit and a few - new tests added. + - Unified the f_name() and the f_name_to() functions. + + DEVELOPER RELATED: - - Some new diffs were added to the patches dir, and some accepted - ones were removed. + - Several diffs in the patches dir now use the proper --enable-FOO + configure option instead of --with-FOO to turn on the inclusion of + the newly patched feature. + - The testsuite now sets HOME so that it won't be affecting by a file + such as ~/.popt.
