Pass THD to find_all_keys() and Item_equal::Item_equal(). In MRR use table->in_use instead of current_thd. This reduces number of pthread_getspecific() calls from 354 to 320.

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.

MDEV-8250: InnoDB: Page compressed tables are not compressed and compressed+encrypted tables cause crash Analysis: Problem is that both encrypted tables and compressed tables use FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION to store required metadata. Furhermore, for only compressed tables currently code skips compression. Fixes: - Only encrypted pages store key_version to FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION, no need to fix - Only compressed pages store compression algorithm to FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION, no need to fix as they have different page type FIL_PAGE_PAGE_COMPRESSED - Compressed and encrypted pages now use a new page type FIL_PAGE_PAGE_COMPRESSED_ENCRYPTED and key_version is stored on FIL header offset FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION and compression method is stored after FIL header similar way as compressed size, so that first FIL_PAGE_COMPRESSED_SIZE is stored followed by FIL_PAGE_COMPRESSION_METHOD - Fix buf_page_encrypt_before_write function to really compress pages if compression is enabled - Fix buf_page_decrypt_after_read function to really decompress pages if compression is used - Small style fixes

Same for _my_b_*_write * create _my_b_cache_write_r instead of having if's in _my_b_cache_write (similar to existing _my_b_cache_read and _my_b_cache_read_r) * don't call mysql_file_write() from my_b_flush_io_cache(), call info->write_function() instead

remove some 14-year old code that added support for LOAD DATA replication to IO_CACHE: * three callbacks, of which only two were actually used and that were only needed for LOAD DATA replication but were tested in every IO_CACHE instance * an additional opaque void * argument in IO_CACHE, also only used for LOAD DATA replication, but present everywhere * the code to close IO_CACHE prematurely in LOAD DATA to have these callbacks called in the correct order and a long comment explaining what will happen if IO_CACHE is not closed prematurely * a variable to track whether IO_CACHE was closed prematurely (to avoid double-closing it)
