- Fix for LP#700623 "Aria recovery: ma_blockrec.c:3930: _ma_update_at_original_place: Assertion `block->org_bitmap_value == _ma_bitmap_get_page_bits(info, &info->s->bitmap, page)' failed" - Issue was that when deleting a tail page where all index entries where full, the page was marked wrongly in the bitmap. - If debug_assert_if_crashed_table is set, we now crash when we find Aria corrupted. - Write more information if we find something wrong with the bitmap. - Fixed that REPAIR also can fix wrong create_rename_lsn issues (a very unlikely event) - Define STATE_CRASHED_FLAGS as set of all CRASHED flags (to simplify code) storage/maria/ha_maria.cc: Mark the normal page cache (not the page cache for the logs) so that we can request extra debugging for it. Copy the value of debug_assert_if_crashed_table to maria_assert_if_crashed_table so that we can request a crash at exactly the point where we find Aria corrupted. Use STATE_CRASHED_FLAGS storage/maria/ma_bitmap.c: Made bits_to_txt extern so that we can use this in maria_chk Added extra information to the log files to be able to easier find bitmap failures in recovery. (When compiling with -DEXTRA_DEBUG_BITMAP) Added _ma_get_bitmap_description() to request a clear text description of the bitmap. Simplify _ma_check_bitmap_data(), as we know the bitmap pattern in the caller. storage/maria/ma_blockrec.c: In delete_head_or_tail(), fixed a bug where we sent wrong information to _ma_bitmap_set() if the directory was full for a page that should be freed. This fixed LP#700623 (failure in bitmap found during recovery) storage/maria/ma_blockrec.h: Added definitions for _ma_get_bitmap_description() and bits_to_txt storage/maria/ma_check.c: Simplify call to _ma_check_bitmap_data(). Write more information if we find something wrong with the bitmap. Moved getting clear text information about the bitmap to ma_bitmap.c::_ma_get_bitmap_description() storage/maria/ma_checkpoint.c: More asserts storage/maria/ma_create.c: Fix wrong create_rename_lsn during repair. (Create_rename_lsn can be too big if someone restores an old maria_log_file after an Aria file was created) storage/maria/ma_delete.c: Call _ma_set_fatal_error() in case of crashed file Remove not needed test of save_errno == HA_ERR_KEY_NOT_FOUND. (Handled by other code storage/maria/ma_extra.c: Call _ma_set_fatal_error() in case of crashed file Reset share->bitmap.changed_not_flushed to not cause new ASSERTS to trigger. Added _ma_file_callback_to_id() for writing share->id to log file in case of DEBUG logging. storage/maria/ma_init.c: Destroy also translog if it's readonly (as when called by maria_read_log -d) storage/maria/ma_key.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_key_recover.c: STATE_CRASHED -> STATE_CRASHED_FLAGS storage/maria/ma_keycache.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_locking.c: Call _ma_set_fatal_error() in case of crashed file. Added _ma_set_fatal_error() storage/maria/ma_open.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_page.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_pagecache.c: Added extra information to log file to simply debugging of bitmap errors. storage/maria/ma_pagecache.h: Added extra_debug flag to allow marking of row and index cache for extra logging (for debugging). storage/maria/ma_panic.c: Flush both data and index blocks in case of HA_PANIC_CLOSE Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code) storage/maria/ma_recovery_util.c: Avoid writing extra not needed \n to DBUG log. storage/maria/ma_rkey.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_search.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/ma_static.c: Define maria_assert_if_crashed_table storage/maria/ma_update.c: Call _ma_set_fatal_error() in case of crashed file. The new code also avoids a problem where we before would print the error twice. storage/maria/ma_write.c: Call _ma_set_fatal_error() in case of crashed file storage/maria/maria_chk.c: STATE_CRASHED -> STATE_CRASHED_FLAGS storage/maria/maria_def.h: Added STATE_CRASHED_PRINTED to avoid giving error message about crash twice. Added STATE_CRASHED_FLAGS to be able to easily detect and set all CRASHED related flags. Added prototypes for new functions. storage/myisam/mi_panic.c: Fixed wrong position of 'break'. (Not critical for MariaDB as MariaDB never uses this code)
