- - 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 of rsync, apply
- the xattrs.diff file from the patches dir.)
-
- - 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 then
- 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 manpage for an
- explanation of the --iconv option's settings.
-
- - Added the --skip-compress=LIST option to override the default list of
- file suffixes that will not be compressed when using --compress.
-
- - The daemon's default for "dont compress" was extended to include:
- *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
- The matching routine was also optimized to run more quickly.
-
- - The --max-delete option now outputs a warning if it skipped any file
- deletions, including a count of how many deletions were skipped. (Older
- versions just silently stopped deleting things.)
-
- - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
- about extraneous files without deleting anything. If you're not sure
- what version the client is, you can use the less-obvious --max-delete=-1,
- as both old and new versions will treat that as the same request (though
- older versions don't warn).
-
- - 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).
-
- - The filter rules now support a perishable ("p") modifier that marks rules
- that should not have an effect in a directory that is being deleted. e.g.
- -f '-p .svn/' would only affect "live" .svn directories.
-
- - If we get an error setting the time on a symlink, we don't complain about
- it anymore (since some operating systems don't support that, and it's not
- that important).
-
- - Protocol 30 now uses MD5 checksums instead of MD4.
-
- - Changed the --append option to not checksum the existing data in the
- destination file, which speeds up file appending.
-
- - Added the --append-verify option, which works like the older --append
- option (verifying the existing data in the destination file). For
- compatibility with older rsync versions, any use of --append that is
- talking protocol 29 or older will revert to the --append-verify method.
-
- - Documented and extended the support for the RSYNC_CONNECT_PROG variable
- that can be used to enhance the client side of a daemon connection.
-
- - Improved the dashes and double-quotes in the nroff manpage output.
-
- - We now support a lot more --no-OPTION override options.
-
- INTERNAL:
-
- - The file-list sorting algorithm now uses a sort that keeps any same-
- named items in the same order as they were specified. This allows
- rsync to always ensure that the first of the duplicates is the one
- that will be included in the copy. The new sort was also faster
- than the glibc version of qsort() and mergesort() in my testing.
-
- - Rsync now supports the transfer of 64-bit timestamps (time_t values).
-
- - Fixed a build problem with older (2.x) versions of gcc.
-
- - Added some isType() functions that make dealing with signed characters
- easier without forcing variables via casts.
-
- - Changed strcat/strcpy/sprintf function calls to use safer versions.
-
- - Upgraded the included popt version to 1.10.2 and improved its use of
- string-handling functions.
-
- - Added missing prototypes for compatibility functions from the lib dir.
-
- - Configure determines if iconv() has a const arg, allowing us to avoid a
- compiler warning.
-
- - Made the sending of some numbers more efficient for protocol 30.
-
- - Make sure that a daemon process doesn't mind if the client was weird and
- omitted the --server option.
-
- - Improved the use of "const" on pointers.
-
- - Improved J.W.'s pool_alloc routines to add a way of freeing older
- sections of a pool's memory.
-
- DEVELOPER RELATED:
-
- - Rsync is now licensed under the GPLv3 or later.
-
- - When running the tests, we now put our per-test temp dirs into a sub-
- directory named testtmp (which is created, if missing). This allows
- someone to symlink the testtmp directory to another filesystem (which is
- useful if the build dir's filesystem does not support ACLs and xattrs,
- and another file system does).
-
- - Rsync now has a way of handling protocol-version changes during the
- development of a new protocol version. This causes any out-of-sync
- versions to speak an older protocol rather than fail in a cryptic manner.
- This addition makes it safe to deploy a pre-release version that may
- interact with the public. This new exchange of sub-version info does not
- interfere with the {MIN,MAX}_PROTOCOL_VERSION checking algorithm (which
- does not have enough range to allow the main protocol number to be
- incremented for every minor tweak in that happens during development).
