Hi Philip, The new version of MWL#121-125, DS-MRR impovements, is ready for your testing. I believe all previously reported crashes and wrong query result bugs are no longer there (they've been either targeted and fixed, or were gone after code re-working I've made when addressing review feedback). The slowdown bugs (https://bugs.launchpad.net/maria/+bug/637160, https://bugs.launchpad.net/maria/+bug/631504) are most likely still there (I didn't check if they are, but I haven't made any changes that could impact them). The code to be tested is at lp:~maria-captains/maria/maria-5.3-mwl128-dsmrr-cpk. BR Sergey -- Sergey Petrunia, Software Developer Monty Program AB, http://askmonty.org Blog: http://s.petrunia.net/blog
