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 --list-only option is now affected by the --human-readable setting. + It will display digit groupings by default, and unit suffixes if higher + levels of readability are requested. Also, the column width for the size + output has increased from 11 to 14 characters when human readability is + enabled. Use --no-h to get the old-style output and column size. + + - 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. + + - Enhanced the --stats output: 1) to mention how many files were created + (protocol >= 28), 2) to mention how many files were deleted (a new line + for protocol 31, but only output when --delete is in effect), and 3) to + follow the file-count, created-count, and deleted-count with a subcount + list that shows the counts by type. The wording of the transferred count + has also changed so that it is clearer that it is only a count of regular + files. BUG FIXES: - - Fixed a crash bug that might appear when --delete was used and - multiple source directories were specified. + - Changed the way --progress overwrites its prior output in order to make + it nearly impossible for the progress to get overwritten by an error. - - Fixed the 32-bit truncation of the file length when generating the - checksums. + - Fixed some rare bugs in --iconv processing that might cause a multibyte + character to get translated incorrectly. - - The --backup code no longer attempts to create some directories - over and over again (generating warnings along the way). + - Improved the propagation of abnormal-exit error messages. This should + help the client side to receive errors from the server when it is exiting + abnormally, and should also avoid dying with an "connection unexpectedly + closed" exit when the closed connection is really expected. - - 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. + ENHANCEMENTS: - - 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.) + - 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. - - 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). + - 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. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - The --msgs2stderr option can help with debugging rsync by allowing the + debug messages to get output to stderr rather than travel via the socket + protocol. - - 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. + - Added the --delete-missing-args and --ignore-missing-args options to + either delete or ignore user-specified files on the receiver that are + missing on the sender (normally the absence of user-specified files + generates an error). - - Got rid of a potential hang in the receiver when near the end of a - phase. + - Added a "T" (terabyte) category to the --human-readable size suffixes. - - When using --backup without a --backup-dir, rsync no longer preserves - the modify time on directories. This avoids confusing NFS. + - Added the --usermap/--groupmap/--chown options for manipulating file + ownership during the copy. - - 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". + - 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). - - 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). + - Added the "reverse lookup" parameter to the rsync daemon config file to + allow reverse-DNS lookups to be disabled. - - 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). + - Added a forward-DNS lookup for the daemon's hosts allow/deny config. Can + be disabled via "forward lookup" parameter (defaults to enabled). - - Fixed a bug in the daemon authentication code when using one of the - batch-processing options. + - Added a way for more than one group to be specified in the daemon's + config file, including a way to specify that you want all of the + specified user's groups without having to name them. Also changed the + daemon to complain about an inability to set explicitly-specified uid/gid + values, even when not run by a super-user. - - 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). + - Added per-user authorization options and group-authorization support to + the daemon's "auth users" parameter. - ENHANCEMENTS: + - Added a way to reference environment variables in a daemon's config file + (using %VAR% references). - - 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. + - When replacing a non-dir with a symlink/hard-link/device/special-file, + the update should now be done in an atomic manner. - - Added the "write only" option to the daemon's config file. + - Fixed a free of the wrong pointer in uncache_tmp_xattrs() (which only + sometimes affects an --xattr transfer when --backup is used). - - Added long-option names for -4 and -6 (namely --ipv4 and --ipv6) - and documented all these options in the man page. + - When backing up a file, try to hard-link the file into place so that the + upcoming replacement of the destination file will be atomic. - - 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 the ability to synchronize nano-second modified times. - - 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 a few more default suffixes for the "dont compress" settings. - - Added the --checksum-seed=N option for advanced users. + - Added the checking of the RSYNC_PROTECT_ARGS environment variable to allow + the default for the --protect-args command-line option to be overridden. - - 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. (Chris Shoemaker) + - Added some Solaris xattr code. - INTERNAL: + EXTRAS: - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. + - Added an "instant-rsyncd" script to the support directory, which makes + it easy to configure a simple rsync daemon in the current directory. - - Improved the argv-overflow checking for a remote command that has - a lot of args. + - 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. - - Use rsyserr() in the various places that were still calling - rprintf() with strerror() as an arg. + INTERNAL: - - 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). + - The I/O code was rewritten to be simpler and do bigger buffered reads + over the socket. The I/O between the receiver and the generator was + changed to be standard multiplexed-I/O (like that over the socket). - - Optimized away a loop in hash_search(). + - The sender tries to use any dead time while the generator is looking for + files to transfer in order to do sender-side directory scanning in a more + parallel manner. - BUILD CHANGES: + - A daemon can now inform a client about a daemon-configured timeout value + so that the client can assist in the keep-alive activity (protocol 31). - - Added a "gen" target to rebuild most of the generated files, - including configure, config.h.in, the man pages, and proto.h. + - The filter code received some refactoring to make it more extendable, to + read better, and do better sanity checking. - - 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). + - Really big numbers are now output using our own big-num routine rather + than casting them to a double and using a %.0f conversion. - - 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. + - The pool_alloc library has received some minor improvements in alignment + handling. - - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. + - Added init_stat_x() function to avoid duplication of acl/xattr init code. 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. + - Added more conditional debug output. + - Changed configure.in to configure.ac.
