- Ported mysql Bug#20597981 test case to mariadb-10.2
- InnoDB never used fts_doc_id_in_read_set. Basically it tells
innodb to read the fts_doc_id from the index record itself.
- Introduce a new variable called innodb_encrypt_temporary_tables which is
a boolean variable. It decides whether to encrypt the temporary tablespace.
- Encrypts the temporary tablespace based on full checksum format.
- Introduced a new counter to track encrypted and decrypted temporary
tablespace pages.
- Warnings issued if temporary table creation has conflict value with
innodb_encrypt_temporary_tables
- Added a new test case which reads and writes the pages from/to temporary
tablespace.
Added the condition in innochecksum tool to check page id mismatch.
This could catch the write corruption caused by InnoDB.
Added the debug insert inside fil_io() to check whether it writes
the page to wrong offset.
The problem was that the code in maria_extra assumed that there could be
only one table open when doing maria_extra(MA_FORCE_REOPEN)
However in the case of triggers, there can be multiple copies of
the table open.
Fixed by removing assert.
Also, move part of the test back to innodb.innodb_mysql
and another part to a new test innodb.purge.
Last but not least, merge the tests innodb_zip.4k and innodb_zip.8k
to innodb_zip.page_size.
MariaDB doesn't support Read-Free replication, so showing them only causes
confusion.
Removed variables:
- @@rocksdb_read_free_rpl
- @@rocksdb_read_free_rpl_tables
The test cases for the MDEV found several independent bugs
in MariaDB server and Aria:
- If a temporary table was marked as crashed, it could never
be deleted.
- Opening of a crashed temporary table gave an error message
but the error was never forwarded to the caller which caused
an assert() in my_ok()
- init_read_record() did mmap of all temporary tables, which is
probably not a good idea as this area can potentially be
very big. Changed code to only mmap internal temporary tables.
- mmap-ed tables where not unmapped in case of repair/optimize
which caused bad data in table and crashes if the original
table files where replaced with new ones (as the old mmap
was still in place). Fixed by removing the mmap in case
of repair.
- Cleaned up usage of code that disabled mmap in Aria
Problem was that in case of implicit rollback for alter table
Aria did try to run commit twice.
The test case for this is tricky to do in 10.2, so it will
be added to 10.4 as part of BACKUP STAGE testing.
in where clause
The classes Item_func_isnottrue and Item_func_isnotfalse inherited the
implementation of the eval_not_null_tables method from the Item_func
class. As a result the not_null_tables_cache was set incorrectly for
the objects of these classes. It led to improper conversion of outer
joins to inner joins when the where clause of the processed query
contained IS NOT TRUE or IS NOT FALSE predicates. The coverted query
in many cases produced a wrong result set.
Restore the detection of default charset in command line utilities.
It worked up to 10.1, but was broken by Connector/C.
Moved code for detection of default charset from sql-common/client.c
to mysys, and make command line utilities to use this code if charset
was not specified on the command line.
There was two separate problems:
- Aria pagecache didn't properly handle re-reading of blocks
that have given errors before (this triggered an assert)
- temporary tables that where opened several times where
not properly closed in ALTER, REPAIR or OPTIMIZE table
Other things
- Added a couple of asserts that will make it easier to
find problems like this in the future.
- Don't add DZSTD_STATIC_LINKING_ONLY
- Don't use upstream's way of linking with Jemalloc (MyRocks/MariaDB has
its own in build_rocksdb.cmake)
- Don't depend on libunwind
