Description

Hi I'm experiencing randomly crashes so I decided to start qgis with gdb to trace the error

I'm on a udpated debian wheezy 64bit with compiled qgis 60dc15e

this is the trace of the abort... seems related to multithread rendering
I've some spatialite layers and spatialite3 with internal provider compilation, but I've also a spatialite debian package installed

let me know if you need more infos

Fix #10127 (crash on parallel rendering of spatialite layers)

There was a run condition in connection pool singleton: at the beginning,
the singleton got initialized twice. Now the singleton is handled
as a static function variable which should be initialized in thread-safe way.

Hi Luigi

that is really quite strange. When a connection is being released back to connection pool, its group should definitely exist because it was created earlier in acquireConnection() call - that's why it crashes on assert.

In theory I could just remove the assertion and ignore the issue, but we should try to investigate it. Please try to add some debug messages to the acquire/release connection functions to better understand what happens - I'm attaching a sample diff. With a next crash it would be good to investigate the sequence of acquire/release messages from the log.

Does it happen only if you use parallel rendering? Or can it happen also with sequential rendering?

#4 Updated by Luigi Pirelli over 10 years ago

I'm not able to understand steps to reproduce the error... happends again after I posted the tiket and I tried to replicate without success. I hope to collect more data.
I'll set sequencial rendering and report if it still crashes

#5 Updated by Luigi Pirelli over 10 years ago

added debug messages... i tried

1) with serial rendering... no crash
2) with parallel rendering... no crash using for long time, colsing and reopening a lot of time... one time after reopened and loaded the project, tried to open contextual menu with right mouse button... crash!
