Does commit wait for post-commit hook to execute?
Hello all,

immediately?

...however this is not a problem for the post-commit hook, since you
can't send any feedback from that hook anyway.
Note that if you want to spawn another process with the intention of
completing the post-commit quicker, you may also need to direct the
spawned process's stdout and stderr to /dev/null, else the post-
commit hook may still wait for the spawned process to complete.

Yes, Subversion will only allow one commit to be taking place at a
given time, so there can only be one post-commit hook running at a
time. However, if you spawn off a process in your post-commit hook,
then the post-commit hook will exit before your script is done, so
there could be multiple copies of your spawned script running at a time.

And probably some kind of semaphore or lock has to be used if it is
important that there is only one spawned script running at the same
time.
Does Subversion assure that the same script won't be executed multiple
at the same time when there are concurrent check-ins?
With best regards

svn commit "finishes" when the post-commit hook completes finishes
executing. If your post-commit is lengthy and you need quicker
response, have post-commit spawn a new process to actually do that
work, letting post-commit return. Doing this in any hook script means
you'll lose the ability to send feedback to the user regarding that
spawned process.
