MDEV-22696 TP_pool_generic::set_pool_size logic so that it marks each connection to change group before the next socket read.

MDEV-22578 thread_pool_info crashes with clang6, using SSE instructions on unaligned memory

2020-05-15T14:29:06+00:00

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.

Merge 10.4 into 10.5

MDEV-20372 thread_pool_info fails randomly in 10.5

2020-03-28T00:46:53+00:00

Rework stats a bit, so we're not missing any queue_get() now.

Don't do stats_reset_table(), if generic threadpool is off.

MDEV-19313 Threadpool : provide information schema tables for internals of generic threadpool

2019-05-26T17:20:35+00:00

Added thread_pool_groups, thread_pool_queues, thread_pool_waits and
thread_pool_stats tables to information_schema.
