- - 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:
-
- - 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.
-
- DEVELOPER RELATED:
-
- - 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).
