- - Added the --skip-compress=LIST option to override the default list of
- file suffixes that will not be compressed when using --compress (-z).
-
- - The daemon's default for "dont compress" was extended to include:
- *.7z *.mp[34] *.mov *.avi *.ogg *.jpg *.jpeg
- The name-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.
-
- - Rsync checks all the alternate-destination args for validity (e.g.
- --link-dest). This lets the user know when they specified a directory
- that does not exist.
-
- - 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.
-
- - Added the --contimeout=SECONDS option that lets the user specify a
- connection timeout for rsync daemon access.
-
- - 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.
-
- - Rsync now supports 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 is also faster
- than the glibc version of qsort() and mergesort().
-
- - Rsync now supports the transfer of 64-bit timestamps (time_t values).
-
- - Made the file-deletion code use a little less stack when recursing
- through a directory hierarchy of extraneous files.
-
- - 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.
-
- - There are more internal logging categories available in protocol 30 than
- the age-old FINFO and FERROR, including FERROR_XFER and FWARN. These new
- categories allow some errors and warnings to go to stderr without causing
- an erroneous end-of-run warning about some files not being able to be
- transferred.
-
- - Improved the use of "const" on pointers.
-
- - Improved J.W.'s pool_alloc routines to add a way of incrementally freeing
- older sections of a pool's memory.
-
- - The getaddrinfo.c compatibility code in the "lib" dir was replaced with
- some new code (derived from samba, derived from PostgreSQL) that has a
- better license than the old code.
