don't return NULL-s anymore, and actually they're not BOOLEAN. Fixed.

The --gtid-ignore-duplicates option was not working correctly with row-based replication. When a row event was completed, but before committing, there was a small window where another multi-source SQL thread could wrongly try to re-execute the same transaction, without properly ignoring the duplicate GTID. This would lead to duplicate key error or out-of-order GTID error or similar. Thanks to Matt Neth for reporting this and giving an easy way to reproduce the issue.

The behaviour required by the standard seems too weird to expect.

Split first_breadth_first_tab() into JOIN::first_breadth_first_optimization_tab() and JOIN::first_breadth_first_execution_tab(). This allows to eliminate function call and one condition. Adjusted callers accordingly. Overhead change: first_breadth_first_tab() 0.07% -> out of radar next_breadth_first_tab() 0.04% -> 0.04% JOIN::cleanup() 0.15% -> 0.11% JOIN::save_explain_data_intern() 0.28% -> 0.24%

Moved Apc_target::destroy(), Apc_target::enable() and Apc_targe::disable() definitions to my_apc.h so that they can be inlined. Apc_targe::disable() now calls Apc_target::process_apc_requests() only if there're APC requests. This saves one pthread_mutex_lock() call. Overhead change: Apc_target::disable 0.04% -> out of radar Apc_target::enable 0.03% -> out of radar Apc_target::process_apc_requests 0.02% -> out of radar pthread_mutex_lock 0.43% -> 0.42% pthread_mutex_unlock 0.26% -> 0.25%

Handle the case where the optimizer decides to use handler->delete_all_rows(), but then this call returns HA_ERR_UNSUPPORTED and execution switches to regular row-by-row deletion.

Do not call handler::rebind_psi() and handler::unbind_psi() when performance schema is compiled out. Overhead change: handler::rebind_psi 0.04% -> out of radar handler::unbind_psi 0.03% -> out of radar open_table 0.21% -> 0.18% close_thread_table 0.05% -> 0.05%

Initialize abs_timeout when it is about to be used. This saves one my_hrtime() call on hot path (when we acquire MDL lock without waiting). When filling I_S.PROCESSLIST use THD::start_utime/THD::utime_after_query instead of THD::start_time. This allows us to save 2 clock_gettime() calls. Overhead change: __clock_gettime 0.13% -> 0.11% (122 -> 76 calls per OLTP RO transaction) my_interval_timer 0.07% -> 0.06% my_hrtime 0.04% -> 0.01%

Added new dynamic configuration variable innodb_buf_dump_status_frequency to configure how often buffer pool dump status is printed in the logs. A number between [0, 100] that tells how oftern buffer pool dump status in percentages should be printed. E.g. 10 means that buffer pool dump status is printed when every 10% of number of buffer pool pages are dumped. Default is 0 (only start and end status is printed).

Follow-up patch to temporarily avoid a sporadic failure in the test rpl.rpl_000011 due to MDEV-8301. There is a window during thread exit where the global status is counted incorrectly - the contribution for the exiting thread is counted twice. The patch for MDEV-8294 made this window visible to the test case rpl.rpl_000011, causing it to sporadically fail. Temporarily silence this with a wait for the expected value; can be removed once MDEV-8294 is fixed.

Analysis: Problem was that actual payload size (page size) after compression was handled incorrectly on encryption. Additionally, some of the variables were not initialized. Fixed by encrypting/decrypting only the actual compressed page size.

MDEV-8268: InnoDB: Assertion failure in file buf0buf.cc line 5842 failing assertion ut_a(free_slot != NULL); Analysis: Problem is that there is not enough temporary buffer slots for pending IO requests. Fixed by allocating same amount of temporary buffer slots as there are max pending IO requests.
