This was because of a wrong test in encryption code that wrote random
numbers over the LSN for pages for transactional Aria tables during repair.
The effect was that after an ALTER TABLE ENABLE KEYS of a encrypted
recovery of the tables would not work.
The test cases will be pushed into 10.5 as it requires of several changes
to check table that safer not to backport.
- Aborting of fulltext index creation fails to remove the
index from sys indexes table. When we try to reload the
table definition, InnoDB fails with index count mismatch
error. InnoDB should remove the index from sys indexes while
rollbacking the secondary index creation.
- 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.
This script is unused and unmaintained.
The logic is implemented in scripts/mysql_system_tables_fix.sql that forms part of mysql_upgrade
Its components:
alter table mysql.user drop column `password_last_changed`, drop column `password_lifetime`, drop column `account_locked`;
has a friendlier migration path coming MDEV-24122
alter table mysql.user change column `authentication_string` `auth_string` text COLLATE utf8_bin NOT NULL;
Already part of scripts/mysql_system_tables_fix.sql
alter table mysql.user add column `Password` char(41) CHARACTER SET latin1 COLLATE latin1_bin NOT NULL DEFAULT '' after `user`, add column `is_role` enum('N','Y') CHARACTER SET utf8 NOT NULL DEFAULT 'N' after `auth_string`;
alter table mysql.user add column `default_role` char(80) COLLATE utf8_bin NOT NULL DEFAULT '', add column `max_statement_time` decimal(12,6) NOT NULL DEFAULT '0.000000';
corrected in MDEV-23201 to be in the right order.
update mysql.user set `password`=`auth_string`, plugin='' where plugin="mysql_native_password";
Is handled in server in the function acl_load.
we need to stop server instance on upgrade, but it may be started either by SysV init script or by SystemD.
this commit adds `mysql` target to `systemctl stop` call.
`mysql` may be the name of initscript or an alias while `mariadb` is
a systemd unit file.
`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.
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 97db6c15ea (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.
Binlog group commit could lead to a situation where group commit leader
accesses participant thd's wsrep client state concurrently with the
thread executing the participant thd.
This is because of race condition in
MYSQL_BIN_LOG::write_transaction_to_binlog_events(),
and was fixed by moving wsrep_ordered_commit() to happen in
MYSQL_BIN_LOG::queue_for_group_commit() under protection of
LOCK_prepare_ordered mutex.
splittable derived
If one of joined tables of the processed query is a materialized derived
table (or view or CTE) with GROUP BY clause then under some conditions it
can be subject to split optimization. With this optimization new equalities
are injected into the WHERE condition of the SELECT that specifies this
derived table. The injected equalities are generated for all join orders
with which the split optimization can employed. After the best join order
has been chosen only certain of this equalities are really needed. The
others can be safely removed. If it's not done and some of injected
equalities involve expressions over semi-joins with look-up access then
the query may return a wrong result set.
This patch effectively removes equalities injected for split optimization
that are needed only at the optimization stage and not needed for execution.

* Remove usage of wsrep_provider variable in galera_ist_restart_joiner
* Rename galera_load_provider.inc and galera_unload_provider.inc to
galera_stop_replication.inc and galera_start_replication.inc. Their
original names were no longer reflecting what these include files do.

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.)
In commit eaeb8ec4b8 (MDEV-24653)
an incorrect debug assertion was introduced.
btr_pcur_store_position(): If the only record in the page is the
instant ALTER TABLE metadata record, we cannot expect there to be
a successor page. The situation could be improved by MDEV-24673 later.
in ON condition
The fix of the bug MDEV-25002 for 10.4 turned out to be incomplete. It
caused crashes when executing CREATE VIEW, CREATE TABLE .. SELECT,
INSERT .. SELECT statements if their SELECTs contained references to
non-existing fields.
This patch complements the fix for MDEV-25002 in order to avoid such
crashes.
