Dovecot doesn't search the index

[filiphanes]

Could you use newest or newer dovecot version?

[zyberzero]

@filiphanes , I've upgraded to the latest dovecot version available in the Debian community package (2.3.17.1 (476cd46418)).

I've recompiled fts-elastic to use the new Dovecot libraries.

Then, if I activate fts-elastic it crashes when selecting an inbox.

I've been playing along with another fts-plugin (fts-xapian more precisely) as well, that works though. As soon as I remove fts-elastic from 90-fts.conf it works again.

One thing that I saw was that the build script tries to include -I/usr/lib/dovecot/src/plugins/fts, but I can find that src folder on that location. It builds cleanly however.

Any ideas how to get further?

Thanks!

[filiphanes]

I didn't tested it on this newest version. It might be bug.
Next ideas to try:

• double check that new compiled module is used
• use older version, maybe around last winter, because it worked for me and other people
• find and fix the bug

@filiphanes before I'd open a new ticket I spotted this one and it might be related... just blindly guessing here... I noticed that I was having errors in the audit logs related to the indexer and apparmor... I had to forcefully disable it and it started working... to be honest I'm using this package but with the fts_lucene

when I try to attempt a search... the error in the logs is audit: type=1400 audit(1668008674.433:303): apparmor="DENIED" operation="exec" profile="dovecot" name="/usr/lib/dovecot/indexer" pid=39020 comm="dovecot" requested_mask="x" denied_mask="x" fsuid=0 ouid=0

I'm not an apparmor expert here, so... I look forward for your feedback

p.s. I have a different mail_location than the one in the default config

quick ref... this is the way to disable apparmor just for doing the indexing https://wiki.archlinux.org/title/AppArmor#Disabling_loading
