[Koha-devel] Elasticsearch not auto-updating after cataloguing

[Philippe Blouin]

Hello Thomas,

I followed your tip the last few days.  At this point I've spotted which 
commit between 21 and 22 moved the reindexing to BackgroundJobs, and 
when set up correctly (the worker), it does reindex indeed.

But if rabbitmq runs, then it fails.   The background_jobs service gets 
the clue to look for job X: if connecte to MQ, it goes to the database 
with a ->find()... and gets nothing.  If MQ is not running, it goes to 
the database with a ->search() and process the jobs there with success.

*sigh*

So it is not a matter of Ubuntu version or remote vs local, but of a 
combination of Koha version, worker and rabbitmq.

NOW, if I put a "sleep 2" in background_jobs_worker.pl, just before the 
->find(), then it works.

Like if the Queue is faster than the Database ??!?!  Seems to me nothing 
is put onto the queue, especially not an ID, without the database entry 
being completed.


I have a feeling I'm deep into a rabbit (mq) hole, and I'm not seeing 
straight.


Thanks a lot,


Philippe Blouin,
