Hi again, some considerations about my last email, that i think should be important to include in next release... About MDEV-4687, i think that it MUST be in next release, i have a stock system with statistic tables that use date based values, and when i use <= to get the last day that have stock values, it return no rows, instead of real rows, this make me crazy for some days and many stock values wrong! i changed those tables to myisam (just to test) and the problem was solved! i put the bug at mariadb jira, and after some time Sergei Petrunia sent a patch that solved the problem, i patched my production server (yes i'm running 10.0.3 on production without big problems, just this one), and now they run nice, please consider this as a very important feature to merge to 10.0.4 release and next 5.5, 5.3, 5.2, 5.1 releases too (i don't know if there's test cases for this, but i tested 10.0.3 and sergei and elena tested 5.5.?) About MDEV-4581 i think it isn't accepted yet since it don't have tests, and have a macro not well defined yet +#ifdef QUERY_CACHE_QC_INFO_PLUGIN /* for more information see MariaDB - MDEV-4682 */ this could be removed without problems (source runs with it definned or not, the MDEV-4682 is statistics about query hits), and run without problems without the MDEV-4682 being accepted (without macro defined and sql_cache.cc/sql_cache.h patch)
