Problem was that a parallel open of a table, overwrote info->state that
was in used by repair.
Fixed by changing _ma_tmp_disable_logging_for_table() to use
a new state buffer state.no_logging to store the temporary state.
Other things:
- Use original number of rows when retrying repair to get rid of a
potential warning "Number of rows changed from X to Y"
- Changed maria_commit() to make it easier to merge with 10.4
- If table is not locked (like with show commands), use the global
number of rows as the local number may not be up to date.
(Minor not critical fix)
- Added some missing DBUG_RETURN
MDEV-10130 Assertion `share->in_trans == 0' failed in storage/maria/ma_close.c
MDEV-10378 Assertion `trn' failed in virtual int ha_maria::start_stmt
The problem was that maria_handler->trn was not properly reset
at commit/rollback and ha_maria::exernal_lock() could get confused
because.
There was some old code in ha_maria::implicit_commit() that tried
to take care of this, but it was not bullet proof.
Fixed by adding list of all tables that is part of the maria transaction to
TRN.
A nice side effect was of the fix is that loops in
ha_maria::implict_commit() got to be much simpler.
Other things:
- Fixed a bug in mysql_admin_table() where argument open_for_modify
was wrongly reset for the next table in the chain
- rollback admin command also in case of fatal error.
- Split _ma_set_trn_for_table() to three version to simplify code
and debugging.
- Several new asserts to detect the original problem (that file was
not properly removed from trn before calling ma_close())
Problem was that if copy_data_between_tables() didn't do proper
clean up in case of failures:
- copy object was not properly freed
- end_bulk_insert() was not called
- mysql_trans_prepare_alter_copy_data() set THD->transaction.on to
false which was not properly restored
The last part caused a crash in Aria as Aria depends on that THD
is correct.
Other things:
- Reset info->switched_transactional after usage (safety)
- Reset bulk_insert_single_undo (safety)
Problem was that we the bitmap needs to be flushed before disabling
logging of redo entires, as writing the bitmap to disk by
background checkpoint may cause redo entries.
Modern compilers (such as GCC 8) emit warnings that the
'register' keyword is deprecated and not valid C++17.
Let us remove most use of the 'register' keyword.
Code in 'extra/' is not touched.
This bug happened due to a defect of the implementation of the handler
function ha_delete_all_rows() for the ARIA engine.
The function maria_delete_all_rows() truncated the table, but it didn't
touch the write cache, so the cache's write offset was not reset.
In the scenario like in the function st_select_lex_unit::exec_recursive
when first all records were deleted from the table and then several new
records were added some metadata became inconsistent with the state of
the cache. As a result the table scan function could not read records
at the end of the table.
The same defect could be found in the implementation of ha_delete_all_rows()
for the MYISAM engine mi_delete_all_rows().
Additionally made late instantiation for the temporary table used to store
rows that were used for each new iteration when executing a recursive CTE.
The merge only covered 10.1 up to
commit 4d248974e0.
Actually merge the changes up to
commit 0a534348c7.
Also, remove the unused InnoDB field trx_t::abort_type.
For some simple benchmarks, a majority of time was
spend in find_head() which tries to find the best
place to put the record.
The result of this patch is a 2x or more speedup for
inserts without keys for format PAGE. All changes
are only related to how rows are stored
Should fix some of the problems mentioned in:
MDEV-8132 Temporary tables using Aria with very poor performance
MDEV-9079 Aria very slow for internal temporary tables
MDEV-5841 Mariadb very poor temporary performance
The following changes where done:
- For rows with a small row length that fits into
a page (818 bytes with 8192 pages), stop as soon as we
hit a match.
- Added markers full_head_size and full_tail_size that tells
us where to start searching on the bitmap page
- Ensure that page->used_size is correctly updated when
bitmap grows. This allows us to stop searching at used_size
- Added code to check that the bitmap variables are correct.
- Fixed a wrong test where we set "first_bitmap_with_space".
This shouldn't have caused any notable problems.
my_safe_alloca()/my_safe_afree() work as alloca() or malloc()/free()
depending on the memory size to allocate, that is, depending on
reclength here. They only work correctly if reclength doesn't
change in the middle.
May also fix: MDEV-14970 "MariaDB crashed with signal 11 and Aria table"
I am not able to reproduce a crash, however there was no protection in
print_keydup_error() if the storage engine reported the wrong key number.
This patch adds such a protection and should stop any further crashes
in this case.
Other things:
- Added extra protection in Aria to not set errkey to more than number of
keys. (Don't think this is cause of this crash, but better safe than
sorry)
- Extend test_if_equal_repl_errors() to handle different cases of
ER_DUP_ENTRY. This is just mainly precaution for the future.
The problem was that max_size was acciently set to 1 in some
cases.
Other things:
- Adjust max_rows if min_rows > max_rows.
- Removed not used variable varchar_length
- Adjusted max_pack_length (safety fix)
This bug happens when locking the same Aria "transactional" table
(page format) more then once with LOCK TABLES and inserting into one
of them with INSERT ... SELECT when the table is empty.
Fixed by ensuring we don't use fast bulk insert if table is opened
twice with LOCK TABLES (as this changes table->s->state)
Code changes:
- Added use_count to MARIA_USED_TABLES to be able to check if
table is opened twice for a statement/lock table
- Don't clear history or reset info->start_state if we
don't have versioning. One reason for the bug was
was that info->start_state was set to point to different
states for the two tables. If there is no versioning
info->start_state should always point to info->s->state.common.
Other things:
- Fixed also some typos that was noticed while scanning the code
- More DBUG_PRINT
