- - You may specify --max-delete=0 to a 3.0.0 client to request that it warn
- about any files that it wants to delete without deleting anything. If
- you're not sure what version the client is, you can use the less-obvious
- --max-delete=-1, as old and new versions will both 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).
-
- - A lot more --no-OPTION override options are now supported.
-
- 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.
-
- - 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.
