- Importing table operation fails to punch the hole in
the filesystem when page compressed table is involved.
To achieve that, InnoDB firstly punches the hole for
the IOBuffer size(1MB). After that, InnoDB should write
page by page when page compression is involved.

Add condition on trx->state == TRX_STATE_COMMITTED_IN_MEMORY in order to
avoid unnecessary work. If a transaction has already been committed or
rolled back, it will release its locks in lock_release() and let
the waiting thread(s) continue execution.

Let BF wait on lock_rec_has_to_wait and if necessary other BF
is replayed.

wsrep_trx_order_before
  If BF is not even replicated yet then they are ordered
  correctly.

bg_wsrep_kill_trx
  Make sure victim_trx is found and check also its state. If
  state is TRX_STATE_COMMITTED_IN_MEMORY transaction is
  already committed or rolled back and will release it locks
  soon.

wsrep_assert_no_bf_bf_wait
  Transaction requesting new record lock should be TRX_STATE_ACTIVE
  Conflicting transaction can be in states TRX_STATE_ACTIVE,
  TRX_STATE_COMMITTED_IN_MEMORY or in TRX_STATE_PREPARED.
  If conflicting transaction is already committed in memory or
  prepared we should wait. When transaction is committed in memory we
  held trx mutex, but not lock_sys->mutex. Therefore, we
  could end here before transaction has time to do lock_release()
  that is protected with lock_sys->mutex.

lock_rec_has_to_wait
  We very well can let bf to wait normally as other BF will be
  replayed in case of conflict. For debug builds we will do
  additional sanity checks to catch unsupported bf wait if any.

wsrep_kill_victim
  Check is victim already in TRX_STATE_COMMITTED_IN_MEMORY state and
  if it is we can return.

lock_rec_dequeue_from_page
lock_rec_unlock
  Remove unnecessary wsrep_assert_no_bf_bf_wait function calls.
  We can very well let BF wait here.

`mallinfo` is deprecated since glibc 2.33 and has been replaced by mallinfo2.
The deprecation causes building the server to fail if glibc version is > 2.33.

Check if mallinfo2 exist on the system and use it instead.

Use like this: cmake -DWITH_ASAN=ON -DWITH_ASAN_SCOPE=ON

The function row_upd_clust_step() is invoking several static functions,
some of which used to commit the mini-transaction in some cases.
If innobase_get_computed_value() would fail due to some reason,
we would fail to invoke mtr_t::commit() and release buffer pool
page latches. This would likely lead to a hanging server later.

This regression was introduced in
commit 97db6c15 (MDEV-20618).

row_upd_index_is_referenced(), row_upd_sec_index_entry(),
row_upd_sec_index_entry(): Cleanup: Replace some ibool with bool.

row_upd_clust_rec_by_insert(), row_upd_clust_rec(): Guarantee that
the mini-transaction will always remain in active state.

row_upd_del_mark_clust_rec(): Guarantee that
the mini-transaction will always remain in active state.
This fixes one "leak" of mini-transaction on DB_COMPUTE_VALUE_FAILED.

row_upd_clust_step(): Use only one return path, which will always
invoke mtr.commit(). After a failed row_upd_store_row() call, we
will no longer "leak" the mini-transaction.

This fix was verified by RQG on 10.6 (depending on MDEV-371 that
was introduced in 10.4). Unfortunately, it is challenging to
create a regression test for this, and a test case could soon become
invalid as more bugs in virtual column evaluation are fixed.

           by compound index

This typo bug may lead to wrong result sets for equi-join queries where
the join operation is supported by a compound index such that the order of
its components differs from the order of the corresponding columns in
the table the index belongs to. The bug manifests itself only when usage
of the BNLH algorithm is forced.

The fix for the bug was provided by Chu Huaxing.

As suggested by Vladislav Vaintroub, let us remove misleading
and malformatted startup messages.

Even if the global variable srv_use_atomic_writes were set, we would
still invoke my_test_if_atomic_write() to check if writes are atomic
with a particular page size.

When using the default innodb_page_size=16k, page writes should be
atomic on NTFS when using ROW_FORMAT=COMPRESSED and KEY_BLOCK_SIZE<=4.

Disabling srv_use_atomic_writes when innodb_file_per_table=OFF does
not make sense, because that is a dynamic parameter.

We also correct the documentation string of innodb_use_atomic_writes
and remove the duplicate variable innobase_use_atomic_writes.

The debug parameter innodb_simulate_comp_failures injected compression
failures for ROW_FORMAT=COMPRESSED tables, breaking the pre-existing
logic that I had implemented in the InnoDB Plugin for MySQL 5.1 to prevent
compressed page overflows. A much better check is already achieved by
defining UNIV_ZIP_COPY at the compilation time.
(Only UNIV_ZIP_DEBUG is part of cmake -DWITH_INNODB_EXTRA_DEBUG=ON.)

AIX doesn't have getgrouplist so ensure function is checked.

The HAVE_POSIX_GETGROUPLIST check was insufficient.

Mariabackup SST fails if "--log-bin" option is added with no value
to command line parameters at server startup. This is because the SST
scripts do not correctly interpret the "--- log-bin" option without a
value. This patch adds correct handling of the "--log-bin" parameter
without value to the general part of the parameter parsing (for SST
scripts) and fixes the problem. Also added a test that checks the
correct operation of the server after the fix.

This partially reverts 66106130

AIX detects tell in the configure however
it really isn't there. Use the my_seek aka lseek
implementation.

If a query with implicit grouping contains in MIN/MAX set function in the
select list over a column that is a part of an index then the query
might be subject to MIN/MAX optimization. With this optimization the
server performs a look-up into an index, fetches a value of the column C
used in the MIN/MAX function and substitute the MIN/MAX expression for this
value. This allows to eliminate the table containing C from further join
processing. In order the optimization to be applied the WHERE condition
must be a conjunction of simple equality/inequality predicates or/and
BETWEEN predicates.
The bug fixed in the patch resulted in fetching a wrong value from the
index used for MIN/MAX optimization. It may happened when a BETWEEN
predicate containing the MIN/MAX value followed a strict inequality.

ha_innobase::info_low(): While collecting statistics for
ANALYZE TABLE, ensure that dict_stats_process_entry_from_recalc_pool()
is not executing on the same table.

We observed result differences for the test innodb.innodb_stats because
dict_stats_empty_index() was being invoked by the background statistics
calculation while ha_innobase::analyze() was executing
dict_stats_analyze_index_level().

Tests with 4096-byte sector size confirm that it is
safe to use O_DIRECT with page_compressed tables.
That had been disabled on Linux, in an attempt to fix MDEV-21584
which had been filed for the O_DIRECT problems earlier.

The fil_node_t::block_size was being set mostly correctly until
commit 10dd290b (MDEV-17380)
introduced a regression in MariaDB Server 10.4.4.

fil_node_t::read_page0(): Initialize fil_node_t::block_size.
This will probably make similar code in fil_space_extend_must_retry()
redundant, but we play it safe and will not remove that code.

Thanks to Vladislav Vaintroub for testing this on Microsoft Windows
using an old-fashioned rotational hard disk with 4KiB sector size.

This patch implements OS_DATA_FILE_NO_O_DIRECT on Windows.

This had been originally added in
mysql/mysql-server@192bb153b675fe09037a53e456a79eee7211e3a7
with the motivation to disable O_DIRECT for the dedicated tablespace
for temporary tables. In MariaDB Server,
commit 5eb53955 (MDEV-12227)
should be a better solution.

The code became orphaned later in
mysql/mysql-server@c61244c0e6c58727cffebfb312ac415a463fa0fe
