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.
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).
