- - Some cleanup in the exclude code has saved some per-exclude memory
- and made the code easier to maintain.
-
- - Improved the argv-overflow checking for a remote command that has a
- lot of args.
-
- - Use rsyserr() in the various places that were still calling rprintf()
- with strerror() as an arg.
-
- - If an rsync daemon is listening on multiple sockets (to handle both
- IPv4 and IPv6 to a single port), we now close all the unneeded file
- handles after we accept a connection (we used to close just one of
- them).
-
- - Optimized the handling of larger block sizes (rsync used to slow to a
- crawl if the block size got too large).
+ - We now use sigaction() and sigprocmask() if possible, and fall back on
+ signal() if not. Using sigprocmask() ensures that rsync enables all the
+ signals that it needs, just in case it was started in a masked state.
