Karaf cache not cleaned after upgrade

[mstormi]

I noticed on various occasions that openHAB didn't start properly after a package upgrade.

On every of these, I had to manually clean the cache to make it finally start (or to proceed after start, actually - it starts in fact but keeps hanging).

@BClark09 I'd prefer if we sort this out before OH 4.3 release Dec 15.

When you mention Karaf cache, do you mean cache and tmp directories inside ${OPENHAB_USERDIR}? or just the .karaf dir?

If cache and tmp, these are indeed removed in the distro's update scripts without condition. (Note that Linuxpkg does this in a similar way). Have you tried completing an upgrade without openHAB running and then looking to see if the files still exist?

If .karaf, what is stored here? I thought it was just the console history?

did not manually remove anything. Used `openhab-cli clean-cache`, can you compare what that does to those dirs you named? Am 14. November 2024 19:40:44 MEZ schrieb Ben Clark ***@***.***>:

Not sure if it helps. I do see sometimes start-up issues (Bindings not all initializing, etc) on the first start after an upgrade. Most of the time I do a stop, clean-cache, restart. However, I was also able to get a clean start after a stop and start without cache clean. Maybe there are sometimes timing issues in the first start after an upgrade. Unfortunately, this seems not to be reproducible.
