If you're running an 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). - - - The "backed up ..." message that is output when at least 2 --verbose - options are specified is now the same both with and without the - --backup-dir option. +NEWS for rsync 2.6.8 (UNRELEASED) +Protocol: 29 (unchanged) +Changes since 2.6.7: BUG FIXES: - - Fixed a crash bug that might appear when --delete was used and - multiple source directories were specified. + - Fixed a bug in the exclude code where an anchored exclude without any + wildcards fails to match an absolute source arg, but only when --relative + is in effect. - - Fixed a 32-bit truncation of the file length when generating the - checksums. + - Improved the I/O code for the generator to fix a potential hang when the + receiver gets an EOF on the socket but the generator's select() call + never indicates that the socket is writable for it to be notified about + the EOF. (This can happen when using stunnel). - - The --backup code no longer attempts to create some directories - over and over again (generating warnings along the way). + - Fixed a problem with the file-reading code where a failed read (such as + that caused by a bad sector) would not advance the file's read-position + beyond the failed read's data. - - 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. + - Fixed a logging bug where the "log file" directive was not being honored + in a single-use daemon (one spawned by a remote-shell connection or by + init). - - 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 rsync cannot honor the --delete option, we output an error and exit + instead of silently ignoring the option. - - 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). + - Fixed a bug in the --link-dest code that prevented special files (such as + fifos) from being linked. - - 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) are now successfully transferred back to the client - (the server used to fail to send the message because the socket - wasn't in the right state for the message to get through). - - - Most transfer 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 and are not affected by this). - - - 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 (avoids 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. - - - Fixed a bug that could cause a slow-to-connect rsync daemon to die - with an error instead of waiting for the connection to finish. - - - Fixed an ssh interaction that could cause output to be lost when the - user chose to combine the output of rsync's stdout and stderr (e.g. - using the "2>&1"). + - The ability to hard-link symlinks and special files is now determined at + configure time instead of at runtime. This fixes a bug with --link-dest + creating a hard-link to a symlink's referent on a BSD system. 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 - Also added support for the RSYNC_PARTIAL_DIR environment variable - that, when found, transforms a regular --partial option (such as - the convenient -P option) into one that also specifies a directory. - - - 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 on - stdin via a remote shell. Also, the old requirement of forcing 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. - - - Each transferred file now gets its permissions and modified-time - updated before the temp-file gets moved into place. Previously, the - finished file would have a very brief window where its permissions - disallowed all group and world access. - - - Added the ability to parse a literal IPv6 address in an "rsync:" URL - (e.g. rsync://[2001:638:500:101::21]:873/module/dir). - - - The daemon's wildcard expanding code can now handle more than 1000 - filenames (it's now limited by memory instead of having a hard-wired - limit). - - INTERNAL: - - - Some cleanup in the exclude code has saved some per-exclude memory - and made the code easier to maintain. - - - Improved the argv-overflow checking for a remote command that has a - lot of args. - - - Use rsyserr() in the various places that were still calling rprintf() - with strerror() as an arg. - - - 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). - - - Optimized the handling of larger block sizes (rsync used to slow to a - crawl if the block size got too large). - - - 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. - - - The file-list that is output when at least 4 verbose options are - specified reports the uid value on the sender even when rsync is - not running as root (since we might be sending to a root receiver). - - 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). + - In daemon mode, if rsync fails to bind to the requested port, the + error(s) returned by socket() and/or bind() are now logged. - - The variable $STRIP (that is optionally set by the install-strip - target's rule) was changed to $INSTALL_STRIP because some systems - have $STRIP already set in the environment. + - When we output a fatal error, we now output the version of rsync in the + message. - - Fixed a build problem when SUPPORT_HARD_LINKS isn't defined. + - The rsyncstats script in "support" has an improved line-parsing regex + that is easier to read and also makes it to parse syslog-generated lines. - - When cross-compiling, the gettimeofday() function is now assumed to - be a modern version that takes two-args (since we can't test it). + - A new script in "support": file-attr-restore, can be used to restore the + attributes of a file-set (the permissions, ownership, and group info) + taken from the cached output of a "find ARG... -ls" command. DEVELOPER RELATED: - - The scripts in the testsuite dir were cleaned up a bit and a few - new tests added. + - Removd two unused configure checks and two related (also unused) + compatibility functions. - - Some new diffs were added to the patches dir, and some accepted - ones were removed. + - The acls.diff patch has been improved quite a bit, with more to come. + - A new patch was added: log-file.diff. This contains an early version of + a future option, --log-file=FILE, that will allow any rsync to log its + actions to a file (something that only a daemon supports at present).
