We now put the configure.sh, config.h.in, and aclocal.m4 files in the
alternate build dir along with the other generated files. This requires
that we create symlinks for configure.ac & m4 in the build dir, which is
handled on the first run of configure or prepare-source. I also changed
the patch-branch handling away from the .gen-stash dir to an automatic
build/$PATCH subdir idiom that will keep each branch's configuration
separated. These automatic build dirs are only used when there is a
.git dir, a build/master dir, and no top-dir Makefile. You'll also
want to have package/make early on your path for optimal ease of use.
- Stop setting the mtime on a file we didn't transfer (or didn't verify
the checksum) when the time diff is within the modify window.
- Stop computing a time difference (-1|0|1) when all we care about is
time equality.
Adding new-style compression that only compresses the literal data that
is sent over the wire and not also matching file data that was not sent.
This new-style compression is compatible with external zlib instances,
and will eventually become the default (once enough time has passed that
all servers support the --new-compress and --old-compress options).
NOTE: if you build rsync with an external zlib (i.e. if you specified
configure --with-included-zlib=no) you will ONLY get support for the
--new-compress option! A client will treat -z as uncompressed (with a
warning) and a server will exit with an error (unless -zz was used).
Files-from data is now sent as multiplexed I/O so that it can mingle
with any messages (such as debug output). Requires protocol 31.
Protocol 31 no longer disables output verbosity in a couple instances
that used to cause protocol issues.
Got rid of MSG_* messages that have implied raw data that follows after
them. We instead send a negative index value as a part of the raw data
stream, which is guaranteed to be output together with the following
data. This only affects the (in-progress) protocol 31 and the (self-
contained) communication stream from the receiver to the generator.
Added --debug=IO and improved --debug=FLIST. Some --debug=IO output
requires --msgs2stderr to be used to see it (i.e. sending a message
about sending a message would send another message, ad infinitum).
If a symlink, device, special-file, or hard-linked file is replacing
an existing non-directory, the new file is created using a temporary
filename and then renamed into place. Also changed the handling of
a cluster of hard-linked symlinks/devices/special-files to always
ensure the first item in the cluster is correct, since it doesn't
really save any significant work to try to find an existing correct
item later in the cluster to link with.
