If you're running a 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). +NEWS for rsync 3.1.0 (UNRELEASED) +Protocol: 31 (changed) +Changes since 3.0.4: + + OUTPUT CHANGES: + + - Output numbers in 3-digit groups by default (e.g. 1,234,567). See the + --human-readable option for a way to turn it off. See also the daemon's + "log format" parameter and related command-line options (including + --out-format) for a modifier that can be used to request digit-grouping + or human-readable output in log escapes. (Note that log output is + unchanged by default.) + + - The output of the --progress option has changed: the string "xfer" was + shortened to "xfr", and the string "to-check" was shortened to "to-chk", + both designed to make room for the (by default) wider display of file + size numbers without making the total line-length longer. Also, when + incremental recursion is enabled, the string "ir-chk" will be used + instead of "to-chk" up until the incremental-recursion scan is done, + letting you know that the value to check and the total value will still + be increasing as new files are found. 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. - - - 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) 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). - - - 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 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 (works around 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. + - Changed the way --progress overwrites its prior output in order to make + it nearly impossible for the progress to get overwritten by an error. 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. + - Added the --remote-option=OPT (-M OPT) command-line option that is useful + for things like sending a remote --log-file=FILE or --fake-super option. - - 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 --info=FLAGS and --debug=FLAGS options to allow finer-grained + control over what is output. Added an extra type of --progress output + using --info=progress2. - - 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 --delete-missing option to delete user-specified files on the + receiver that are missing on the sender (normally the absence of user- + specified files generates an error). - - The daemon's "refuse options" config item now allows you to match - option names using wildcards and/or the single-letter option names. + - Added a "T" (terabyte) category to the --human-readable size suffixes. - - The finished file now gets its permissions and modified-time updated - before it gets moved into place. + - Enhanced the --stats output: 1) to mention how many files were created + (protocol >= 28), 2) to mention how many files were deleted (new for + protocol 31), and 3) to follow the file-count, created-count, and + deleted-count with a break-out list of each count by type. - INTERNAL: + - Added the --usermap/--groupmap/--chown options for manipulating file + ownership during the copy. - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - Added the "%C" escape to the log-output handling, which will output the + MD5 checksum of any transferred file, or all files if --checksum was + specified (when protocol 30 or above is in effect). - - Improved the argv-overflow checking for a remote command that has a - lot of args. + - Added the "reverse lookup" parameter to the rsync daemon config file to + allow reverse-DNS lookups to be disabled. - - Use rsyserr() in the various places that were still calling rprintf() - with strerror() as an arg. + - Added a way for supplementary groups to be specified in the rsyncd.conf + file. Also made explicitly-set uid/gid values no longer ignored by a + daemon that was not run by a super-user. - - 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). + EXTRAS: - - Optimized the handling of larger block sizes (rsync used to slow to a - crawl if the block size got too large). + - Added an "instant-rsyncd" script to the support directory, which makes + it easy to configure a simple rsync daemon in the current directory. - - 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. - - 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. + - Added the "mapfrom" and "mapto" scripts to the support directory, which + makes it easier to do user/group mapping in a local transfer based on + passwd/group files from another machine. DEVELOPER RELATED: - - The scripts in the testsuite dir were cleaned up a bit and a few - new tests added. + - Added more conditional debug output. + + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - - Some new diffs were added to the patches dir, and some accepted - ones were removed. + - The pool_alloc library has received some minor improvements in alignment + handling. + - Added init_stat_x() function to avoid duplication of acl/xattr init code.
