Pierre-Yves David <pierre-yves.david@octobus.net> [Mon, 27 Aug 2018 12:40:47 +0200] rev 4014

Pierre-Yves David <pierre-yves.david@octobus.net> [Mon, 27 Aug 2018 11:40:32 +0200] rev 4011
sqlcache: protect read query too Some error (like locked database) can even happens when doing readonly operation. So we protect them too. At that point, it seems that pysqlite3 is not the right tool for this job.

Pierre-Yves David <pierre-yves.david@octobus.net> [Mon, 27 Aug 2018 11:33:09 +0200] rev 4010

sqlcache: initialize meta table last It turns out that pysqlite commit after each table creation. This commit is an hopeless attemps to make the caches more concurrent friendly.
