This failure was caused because of several bugs:
- Someone had removed s3-slave-ignore-updates=1 from slave.cnf, which
caused the slave to remove files that the master was working on.
- Bug in ha_partition::change_partitions() that didn't reset m_new_file
in case of errors. This caused crashes in ha_maria::extra() as the
maria handler was called on files that was already closed.
- In ma_pagecache there was a bug that when one got a read error one a
big block (s3 block), it left the flag PCBLOCK_BIG_READ on for the page
which cased an assert when the page where flushed.
- Flush all cached tables in case of ignored ALTER TABLE
Note that when merging code from 10.3, that fixes the partition bug, use
the code from this patch instead.
Changes to ma_pagecache.cc written or reviewed by Sanja
Temporarily disable failing S3 tests to allow the suite to run in buildbot:
s3.partition and s3.partition_move are disabled due to MDEV-23648.
While the problem is supposedly generic, the tests don't fail with Amazon
setup, so they are disabled conditionally for emulator (MinIO).
s3.replication_partition is disabled due to MDEV-23730,
it fails both with Amazon and MinIO.
s3.replication_mixed and s3.replication_stmt are disabled due to MDEV-23770,
they also fail both with Amazon and the emulator.
