Fix the code that writes the options and the default destination path
into the batch.sh file to be able to handle options being specified
after source/dest args.
I replaced git-set-file-times with an improved version that I wrote
recently (in python3). A new script uses it to figure out the
last-modified year for each *.[ch] file and updates its copyright.
It also puts the latest year into the latest-year.h file for the
output of --version.
The default value of the skip-compress list actually comes from the
daemon's default lp_dont_compress() value, but a while back the vars
stopped getting default values in a non-daemon run. I added a call to
reset_daemon_vars() so that the "Vars" values get set from "Defaults".
On BSD-ish systems you can type Ctrl+T to see the current file and
the progress output (in --info=progress2 format). On hosts w/o
SIGINFO, use something like "killall -VTALRM rsync" or a more
targetted "kill -VTALRM PID ..." call (as needed).
This can be used by a root-run rsync to try to make reading or writing
files safer in a situation where you can't run the whole rsync command
as a non-root user.
- The receiver now sends keep-alive messages to the generator
when it is actively doing work and hasn't sent anything
recently. This ensures that the generator won't timeout
if the receiver is working hard.
- The perform_io() code has improved keep-alive participation.
- Allow the sender to send some keep-alive messages, which
ensures that if it is in a lull, it can probe the socket.
The receiving side also switches timeout handling from the receiver to
the generator, which obviates the need for the sender to send any
keep-alive messages at all (for protocol 31 and beyond). Given this
setup, all keep-alive messages are now sent as empty MSG_DATA messages,
with MSG_NOOP messages only being understood and (when necessary) acted
upon to forward a keep-alive event to an older receiver. This is both
safer and more compatible with older versions.
