the sender, and the file-list is large.

- We now check if the OS doesn't support using mknod() for creating
FIFOs and sockets, and compile-in using mkfifo() and socket() when

(the preserved) attributes from the version in the compare-dest DIR.

ENHANCEMENTS:
- Rsync now supports popt's option aliases, which means that you can

inside the transfer).
- - Added support for specifying multiple --compare-dest or --link-dest
- options, but only of a single type. (Promoted from the patches dir
- and enhanced.)
+ - Added the --copy-dest option, which works like --link-dest except
+ that it copies identical files instead of hard-linking them.

+ --link-dest options, but only of a single type. (Promoted from the

literals in the rsync://HOST:PORT/PATH format.)
+ - When rsync recurses to build the file list, it no longer keeps open
+ the directory handles of all the parent dirs inside the transfer.
+
- When building under windows, the default for --daemon is now to
avoid detaching, requiring the new --detach option to force rsync
to detach.
+ - The --dry-run option can now be combined with either --write-batch or
+ --read-batch, allowing you to run a do-nothing test command to see
+ what would happen without --dry-run.

- Improved the option descriptions in the --help text.
SUPPORT FILES:
generator now transmits an index and a flag-word to indicate when
dirs and symlinks have changed (instead of producing a message),
which makes the outputting of the information more consistent and
- less prone to screen corruption (because either the receiver or the
- sender is now outputting all the file-change info).
-
- - If --inplace is specified, the generator flags any transfer that is
- using an alternate basis file so that the sender can use the entire
- basis file in the rsync algorithm (unlike a normal --inplace update).

+
+ - If a file is being transferred with an alternate-basis file, the

+ length string that has its size written prior to the string, and
+ no terminating null. If the string is from 1-127 bytes, the length

- The sending of exclude names is done using filter-rule syntax. This
means that all names have a prefixed rule indicator, even excludes

wire (each expressed in thousandths of a second).
