Ah of course, rebuild_zebra.pl itself has lock system.
It ends if you dont use --wait-for-lock.
Thanks ;)

There's no need for a couple reasons.
First, all child process operations for my "zebra_indexer.pl" (ie checking for
records to index and the actual indexing) cause the parent indexing daemon to block (by
using waitpid($pid,0)) so there should be no overlapping runs.
Second, even if multiple rebuild_zebra.pl processes were launched magically,
the built-in locking in rebuild_zebra.pl would prevent any but the 1st process
from running.
So it's all good 😃

which is more memory efficient
Oooh nice.
Is there a protection against several launch ? Like in actual daemon
--wait-for-lock ?
Or is there no need ?

Hello David,
thanks for sharing, it looks great! We are going to test it on one of
our servers. We'll report how things are going probably in few days...

Hi all,____

I’ve written a new indexing daemon for Zebra which you can find at
https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=27267
<https://bugs.koha-community.org/bugzilla3/show_bug.cgi?id=27267>.
It’s dead easy to use. Once the daemon is installed, you just need
to update /etc/default/koha-common and you’ll be using it.____
__ __
It only uses 6MB of RAM (instead of the 170-180MB I’ve seen
rebuild_zebra.pl <http://rebuild_zebra.pl> use in daemon mode), so
it scales well on servers that host many instances of Koha. (For
example, if you have 50 Koha instances on a server, you’ll use 300MB
instead of 9GB for idle Zebra indexing daemons.) That said, this
indexing daemon does launch rebuild_zebra.pl
<http://rebuild_zebra.pl> in non-daemon mode when necessary, so you
still need to have memory available to do actual work. Making
rebuild_zebra.pl <http://rebuild_zebra.pl> more memory efficient is
another task in itself and not a pressing issue atm.____
__ __
I’m planning to use it shortly myself, but I figured that I would
share it with everyone else, so that everyone else could benefit
from it too. ____
__ __
Hope others enjoy it as much as I do.____
