rsync - Sep 2005 - Rsync patch for default ACLs and executability

I wrote a patch for rsync 2.6.6 that changes two things:

(1) When the receiving rsync creates a file in a directory with a
default ACL and `--perms' is off, rsync uses the default ACL instead of
the umask to calculate the new file's permissions.  All programs that
just use `open' and don't do an explicit `chmod' are
forward-compatible
with default ACLs, but rsync always sets permissions itself, so it had
to be modified to handle default ACLs correctly.

(2) Even if `--perms' is off, rsync preserves executability of files.
The precise semantics are explained in the patched man page.

The patch is attached.  If you're interested in these features, please
test it and tell me if you have any problems with it.  I request that
the patch be included in the `patches' directory of the next release of
rsync if it is found to work correctly.

A while ago, I wrote to the list:

In case it matters to anyone:

I've been using the patched rsync (actually, I made additional changes
after that patch) and it works decently...but I've convinced myself that
any attempt to get rsync to observe default permissions cleanly and
correctly in all cases is doomed to failure due to the many "chmod"
calls it uses.  Oh well.

Perhaps the fancy pluggable tar/rsync program, if it is ever written,
could do better.
