The bug was based on wrong undo data in recovery file and not enough checking of bad data.
sql/sql_select.h:
Added comment
storage/maria/ma_blockrec.c:
- Removed wrong sanity checks (didn't work for UNDO records)
- More sanity checks and DBUG_ASSERT
- More DBUG_ENTER and DBUG_PRINT
- Removed filler blocks in extent_to_bitmap_blocks() as it caused problems in write_block_record().
This was the main cause of the bug.
(This change can make records generated by UNDO slightly smaller than original record, which we have to fix
by correcting row_pos.length before calling write_block_record())
- Fixed some problems in write_block_record() while doing UNDO.
- Store header_length without TRANSID_SIZE into recovery log (as UNDO entires doesn't have TRANSID_SIZE)
- Mark table crashed if something goes wrong during UNDO
storage/maria/maria_def.h:
Added header_length
