Vladislav Vaintroub	e6f0371556	MDEV-22696 TP_pool_generic::set_pool_size logic so that it marks each connection to change group before the next socket read.	2020-05-25 14:54:11 +02:00
Vladislav Vaintroub	69077dea25	MDEV-22578 thread_pool_info crashes with clang6, using SSE instructions on unaligned memory ... Apparently, in stats_reset_table(), the innocuous memset(&group->counters, 0, sizeof(group->counters)); is converted by clang to SSE2 instructions. The problem is that "group" is not correctly aligned, despite MY_ALIGNED(CPU_LEVEL1_DCACHE_LINESIZE) in the thread_group_t declaration. It is not aligned because it was allocated with my_malloc, since commit fd9f1638, MDEV-5205. Previously all_groups was a statically allocated array. Fix is to remove MY_ALIGNED, and pad the struct instead.	2020-05-15 16:29:06 +02:00

Vladislav Vaintroub	e129555462	MDEV-20372 thread_pool_info fails randomly in 10.5 ... Rework stats a bit, so we're not missing any queue_get() now. Don't do stats_reset_table(), if generic threadpool is off.	2020-03-28 01:46:53 +01:00
Vladislav Vaintroub	2fc13d04d1	MDEV-19313 Threadpool : provide information schema tables for internals of generic threadpool ... Added thread_pool_groups, thread_pool_queues, thread_pool_waits and thread_pool_stats tables to information_schema.	2019-05-26 19:20:35 +02:00
