which nobody woke up (see comment of ma_bitmap.c). No testcase, this requires
multiple threads and is automatically tested at push time by maria_stress.yy (pushbuild2).
storage/maria/ma_bitmap.c:
* _ma_bitmap_wait_or_flush() didn't publish that it was waiting for bitmap to not
be over-allocated (i.e. didn't modify bitmap->flush_all_requested) so nobody
(_ma_bitmap_flushable(), _ma_bitmap_release_unused()) knew it had to wake it up
=> it stalled (BUG#39210). In fact the wait in _ma_bitmap_wait_or_flush()
is not needed, it's ok if this function sends the over-allocated bitmap to page
cache and keeps pin on it (_ma_bitmap_unpin_all() will unpin it later, and
the one who added _ma_bitmap_wait_or_flush() didn't know it). Function
is thus deleted, as _ma_bitmap_flush() can do its job.
* After fixing that, test runs longer and BUG 39665 happens, which looks like
a separate page cache bug.
* Smaller changes: _ma_bitmap_flush_all() called write_changed_bitmap() even
though it might not be changed; added some DBUG calls in functions; split
assertions.
* In _ma_bitmap_release_unused(), it's more logical to test non_flushable_state
than now_transactional to know if we have to decrement non_flushable
(it's exactly per the definition of non_flushable_state).
storage/maria/ma_blockrec.c:
_ma_bitmap_wait_or_flush() is not needed.

new prototype and splitting assertion in three (3rd one fires: BUG 39665)
storage/maria/ma_blockrec.h:

- The problem was that we didn't inform the handler that we are going to close tables that are locked and may have (at least in Maria) be part of an active transaction.
Fix for Bug#39227 Maria: crash with ALTER TABLE PARTITION
Fix for Bug #39987 main.partition_not_windows fails under debug build
Fixed some compiler errors & warnings found by pushbuild
include/my_base.h:
Added HA_EXTRA_PREPARE_FOR_FORCED_CLOSE for signaling the handler that the file will be forced closed
include/my_global.h:
Removed 'register' from 'swap_variables' as this gives a warnings when the variables are structs. Compilers should also now be smart enough to figure out this themselves
mysql-test/r/subselect_debug.result:

Ensure that we call extra() for HA_EXTRA_PREPARE_FOR_DROP (Bug#39227)
sql/mysqld.cc:
Fix for Bug #39987 main.partition_not_windows fails under debug build
The problem was that when compiling for purify/valgrind realpath() is not used, which causes test_if_data_home_dir to fail when it shouldn't
sql/sql_base.cc:
Call HA_EXTRA_PREPARE_FOR_FORCED_CLOSE for tables that are locked but we are going to force close without doing a commit
sql/sql_parse.cc:
More DBUG_PRINT. Fixed comments
storage/maria/ma_extra.c:
If HA_EXTRA_PREPARE_FOR_FORCED_CLOSE is called and the table is part of a transaction, remove the table from beeing part of a transaction.
This is safe as this is only used as part of flush tables or when the table is not part of a transaction

It was a forgotten rw_unlock(), due to the deadlock detector feature (so bug was only in 5.1-maria, not

mysql-test/suite/maria/t/maria3.test:
Test of BUG#39697: two scenarios (transactional tables, and non-transactional table but dynamic row format so still taking the rwlock) where the hang happened.

partition is corrupt
The main problem was that ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR
PARTITION took another code path (over mysql_alter_table instead of
mysql_admin_table) which differs in two ways:
1) alter table opens the tables in a different way than admin tables do
resulting in returning with error before it tried the command
2) alter table does not start to send any diagnostic rows to the client
which the lower admin functions continue to use -> resulting in
assertion crash
The fix:
Remapped ALTER TABLE t ANALYZE/CHECK/OPTIMIZE/REPAIR PARTITION to use
the same code path as ANALYZE/CHECK/OPTIMIZE/REPAIR TABLE t.
Adding check in mysql_admin_table to setup the partition list for
which partitions that should be used.
Partitioned tables will still not work with
REPAIR TABLE/PARTITION USE_FRM, since that requires moving partitions
to tables, REPAIR TABLE t USE_FRM, and check that the data still
fulfills the partitioning function and then move the table back to
being a partition.
NOTE: I have removed the following functions from the handler
interface:
analyze_partitions, check_partitions, optimize_partitions,
repair_partitions
Since they are not longer needed.

this was true also for INSERT SELECT, UPDATE, DELETE. This fix will be removed when Maria supports COMMIT/ROLLBACK
