A long day spent making CommandCleanup actions run in a separate job pool
|
||
|
|
than CommandPerform actions. I don't think this will speed anything up much
|
||
|
|
yet, but it's useful groundwork. Now expensive things that are not
|
||
|
|
the main action of a command can be moved into CommandCleanup and won't
|
||
|
|
delay git-annex moving on to the next file. The main thing I want to move
|
||
|
|
is checksum verification after a transfer. But there are probably other
|
||
|
|
things I have not thought of.
|
||
|
|
|
||
|
|
CommandCleanup was always not well distinguised from CommandPerform,
|
||
|
|
and so there was little incentive to put things in it. Now that's changed.
|
||
|
|
|
||
|
|
I also noticed that with -J, git-annex takes significantly longer than
|
||
|
|
without to get started, when the first file it needs to process is quite a
|
||
|
|
way down the ls-tree. This must be concurrency overhead. But, when
|
||
|
|
CommandStart is skipping over a file that it doesn't need to process,
|
||
|
|
there is no need to do that bookkeeping. Planning to take some time
|
||
|
|
tomorrow to see if I can refactor CommandStart to avoid that overhead.
