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 3.0.0 (UNRELEASED) +Protocol: 30 (changed) +Changes since 2.6.9: 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. + - Fixed the output of -ii when combined with one of the --*-dest options: + it now itemizes all the items, not just the changed ones. - - 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). + - 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. - - 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). + - 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. - - 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). + - A negated filter rule now sends the negation option when sending the + filter rules. - - 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. + - Fixed a problem with the --out-format (aka --log-format) option: it + would output superfluous directory information for a non-daemon rsync. - - 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 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. - - Fixed an age-old crash problem with --read-batch on a local copy - (rsync was improperly assuming --whole-file for the local copy). + - 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. - - 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. + - Make sure that directory permissions of a newly-created destination + directory are handled right when --perms is left off. 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. - - - 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. - - - 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. - - - The finished file now gets its permissions and modified-time updated - before it gets moved into place. + - A new incremental-recursion algorithm is now used when rsync is talking + to another 3.0.0 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. + + - 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. + + - 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. (If you need + to have backward compatibility with old, patched versions, the new + acls.diff patch that will add that.) + + - 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, the new + xattrs.diff patch that will add that.) + + - 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 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 man page for an explanation of the --iconv + option's settings. + + - You may specify --max-delete=0 to a 3.0.0 client as long as the receiving + side is at least version 3.0.0. This means that you can pull from an + older rsync with this option, but pushing to an older rsync will generate + an error. *Be sure to never specify a 0 value to an older rsync client, + or it will be silently ignored.* + + - 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). 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. + - Rsync now supports the transfer of 64-bit timestamps (time_t values). - - 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). + - Fixed a build problem with older (2.x) versions of gcc. - - Optimized the handling of larger block sizes (rsync used to slow to a - crawl if the block size got too large). + - Added some isType() functions that make dealing with signed characters + easier without forcing variables via casts. - - Optimized away a loop in hash_search(). + - Upgraded the included popt version to 1.10.2 and improved its use of + string-handling functions. - - 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). + - Added missing prototypes for compatibility functions from the lib 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. + - Configure determines if iconv() has a const arg, allowing us to avoid a + compiler warning. - BUILD CHANGES: + - Made the sending of some numbers more efficient for protocol 30. - - Added a "gen" target to rebuild most of the generated files, - including configure, config.h.in, the man pages, and proto.h. + - Make sure that a daemon process doesn't mind if the client was weird and + omitted the --server option. - - 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. + - Improved the use of "const" on pointers. DEVELOPER RELATED: - - The scripts in the testsuite dir were cleaned up a bit and a few - new tests added. - - - Some new diffs were added to the patches dir, and some accepted - ones were removed. - + - 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 (which would be the case if every minor change made + to the protocol in CVS incremented the main PROTOCOL_VERSION value).
