MDEV-33325 Crash in flst_read_addr on corrupted data
flst_read_addr(): Remove assertions. Instead, we will check these
conditions in the callers and avoid a crash in case of corruption.
We will check the conditions more carefully, because the callers
know more exact bounds for the page numbers and the byte offsets
withing pages.
flst_remove(), flst_add_first(), flst_add_last(): Add a parameter
for passing fil_space_t::free_limit. None of the lists may point to
pages that are beyond the current initialized length of the
tablespace.
trx_rseg_mem_restore(): Access the first page of the tablespace,
so that we will correctly recover rseg->space->free_limit
in case some log based recovery is pending.
ibuf_remove_free_page(): Only look up the root page once, and
validate the last page number.
MDEV-31779 Server crash in Rows_log_event::update_sequence upon replaying binary log
The crash at running mysqlbinlog on a SEQUENCE containing binlog file
was caused MDEV-29621 fixes that did not check which of the slave
or binlog applier executes a block introduced there.
The block is meaningful only for the parallel slave applier, so
it's safe to fix this bug with identified the actual applier and
skipping the block when it's the mysqlbinlog one.
MDEV-33813 ERROR 1021 (HY000): Disk full (./org/test1.MAI); waiting for someone to free some space
Fixed that internal temporary tables are not waiting for freed disk space.
Other things:
- 'kill id' will now kill a query waiting for free disk space instantly.
Before it could take up to 60 seconds for the kill would be noticed.
- Fixed that sorting one index is not using MY_WAIT_IF_FULL for temp files.
- Fixed bug where share->write_flag set MY_WAIT_IF_FULL for temp files.
It is quite hard to do a test case for this. Instead I tested all
combinations interactively.
