MDEV-28122 Optimize table crash while applying online log
- InnoDB fails to check the overflow buffer while applying
the operation to the table that was rebuilt. This is caused
by commit 3cef4f8f0fc88ae5bfae4603d8d600ec84cc70a9 (MDEV-515).
Do not create histograms for single column unique key
The intentention was always to not create histograms for single value
unique keys (as histograms is not useful in this case), but because of
a bug in the code this was still done.
The changes in the test cases was mainly because hist_size is now NULL
for these kind of columns.
MDEV-32272 lock_release_on_prepare_try() does not release lock if supremum bit is set along with other bits set in lock's bitmap
The error is caused by MDEV-30165 fix with the following commit:
d13a57ae8181f2a8fbee86838d5476740e050d50
There is logical error in lock_release_on_prepare_try():
if (supremum_bit) lock_rec_unlock_supremum(*cell, lock);
else lock_rec_dequeue_from_page(lock, false);
Because there can be other bits set in the lock's bitmap, and the lock
type can be suitable for releasing criteria, but the above logic
releases only supremum bit of the lock.
The fix is to release lock if it suits for releasing criteria and unlock
supremum if supremum is locked otherwise.
Tere is also the test for the case, which was reported by QA team. I
placed it in a separate files, because it requires debug build.
MDEV-31098 InnoDB Recovery doesn't display encryption message when no encryption configuration passed
- InnoDB fails to report the error when encryption configuration
wasn't passed. This patch addresses the issue by adding
the error while loading the tablespace and deferring the
tablespace creation.
