Improve documentation of performance_schema tables by appending COLUMN
comments to tables. Additionally improve test coverage and update corresponding
tests.
This is part of the patch covering newer columns and tables in 10.5.
FTS indexes has a prefix_len=1 or prefix_len=0 as stated by comment in
mysql_prepare_create_table().
Thus, a newly added assertion should be relaxed for FTS indexes.
Any modification of buf_pool.page_hash is supposed to be protected
by buf_pool.mutex and page_hash_latch::write_lock(). The buffer pool
watch mechanism of the InnoDB change buffer was violating that
ever since commit b1ab211dee (MDEV-15053).
buf_pool_t::watch_set(): Extend the critical section of buf_pool.mutex.
buf_pool_t::watch_unset(): Define non-inline, because
calls are infrequent and this function became larger.
If we have to detach a sentinel from page_hash,
do it while holding both the mutex and the exclusive hash latch.
buf_pool_t::watch_remove(): Assert that the mutex is being held.
buf_page_init_for_read(): Remove some work-arounds for
previously encountered race conditions related to buf_pool.watch.
Bug happens when partially indexed CHAR or VARCHAR field in converted from
utf8mb3 to utf8mb4.
Fixing by relaxing assertions. For some time dict_index_t and dict_table_t
are becoming not synchronized. Namely, dict_index_t has a new prefix_len which
is a multiple of a user-provided length and charset->mbmaxlen. But
the table still have and old mbmaxlen and assertion fails. This happens only
during utf8mb3 -> utf8mb4 conversions and the magic number 4 comes from
utf8mb_4_.
At the end of ALTER TABLE (innobase_rename_or_enlarge_columns_cache())
dict_index_t and dict_table_t became synchronized
again and will stay so at all times. For, example, they will be synchronized
on table load and newly added assertion proves that.

comments to tables. Additionally improve test coverage and update corresponding
tests.
failed upon killed TRUNCATE
Note: This is a backport of 1cb4caa66d from
10.3
Analysis: Assertion failure happens because less session memory is set and so
table can't be reopened. So the statement can't be used. This error goes
unreported.
Fix: Return the error state.
buf_read_page_background(): Remove the parameter "bool sync"
and always actually initiate a page read in the background.
buf_load(): Always submit asynchronous reads. This allows
page checksums to be verified in concurrent threads as
soon as the reads are completed.
* Update wsrep-lib which contains the fix
* Add deterministic test case that reproduces the assertion

The server crashed when SPIDER_DIRECT_SQL UDF was called with
non-existing temporary table.
The bug has been introduced by 91ffdc8. The commit removed
the check, from THD::open_temporary_table(), which ensure that
the target temporary tables exist.
We can fix the bug by adding the check before the call of
THD::open_temporary_table().

Thanks Marek Szuba for the bug report and testing the patch.
This is a side-effect of my_large_malloc() introduction,MDEV-18851
It removed a cast to size_t to variable 'blocks' in
multiplication blocks * keycache->key_cache_block_size , creating ulong value
instead of correct size_t.
Replaced a couple of ulongs with appropriate data type, which is size_t.
Also, fixed casts to ulongs in crash handler messages, so that people would
not be confused by that, too.
Interestingly, aria did not expose the same problem even if it contains
copied and pasted code in ma_pagecache, because Aria had some ulongs removed
when fixing a similar problem in MDEV-9256.
Allow the caller to have current_thd. Also do not store
PSI_CALL_get_thread() in the new THD, it is a thread local storage variable
that can become invalid any time, we do not control the lifetime of the
caller's thread.
This stress tests fails on not sufficiently tweaked windows boxes,due
to rapid succession of connects and disconnects, making Windows run out
of ephemeral ports.
Approved by author of the test (the author is happy to see it removed)
Other things:
- Don't allocate an IO_CACHE for scanning tables of type BLOCK
(It was never used in this case)
- Fixed bug in page cache that cased a hang when trying to read a
not existing S3 block.
These options was needed in some cases, like when using minio that require
the port option, to be able to connect to the S3 storage.
The sympthom was that one could get the error
"Table t1.MAI doesn't exist in s3"
even if the table did exits.
Other things:
- Improved error message for non existing S3 files
buggy regexp in old CPackRPM.cmake:
string(REGEX REPLACE "%[A-Za-z0-9\(\),-]* " "" F_PATH ${F})
string(REGEX MATCH "%[A-Za-z0-9\(\),-]*" F_PREFIX ${F})
it treats everything after the first space as a path
THD::copy_db_to(): Always return true if the output parameter
was left uninitialized. This fixes a regression that was caused
by commit 7d0d934ca6 (MDEV-16473).
MariaDB Server 10.3 and later were unaffected by this bug
thanks to commit a7e352b54d.
Possibly this bug only affects mysql_list_fields()
in the Embedded Server (libmysqld).
This bug was found by GCC 11.2.0 in CMAKE_BUILD_TYPE=RelWithDebInfo.
