btr_lift_page_up(): If the leaf page only contains a hidden metadata
record for MDEV-11369 instant ADD COLUMN, convert the table to the
canonical format like we are supposed to do whenever the table
becomes empty.
Use suspend thread syncpoint instead of include/wait_condition.inc to
make sure DELETE created waiting lock before the next UPDATE begins
locking.
This is backport of commit 0fa4dd0747
from 10.6.
dict_table_rename_in_cache(), dict_table_get_highest_foreign_id():
Reserve sufficient space for the fkid[] buffer, and ensure that the
fkid[] will be NUL-terminated.
The fkid[] must accommodate both the database name (which is already
encoded in my_charset_filename) and the constraint name
(which must be converted to my_charset_filename) so that we can check
if it is in the format databasename/tablename_ibfk_1 (all encoded in
my_charset_filename).
trx_undo_page_report_rename(): Use the correct maximum length of
a table name. Both the database name and the table name can be up to
NAME_CHAR_LEN (64 characters) times 5 bytes per character in the
my_charset_filename encoding. They are not encoded in UTF-8!
fil_op_write_log(): Reserve the correct amount of log buffer for
a rename operation. The file name will be appended by
mlog_catenate_string().
rename_file_ext(): Reserve a large enough buffer for the file names.
Ever since commit 09177eadc3
the test innodb.row_format_redundant cannot work when the
data file was created with innodb_checksum_algorithm=full_crc32.
Backport of 10.5 commit a9d0bb12e6
- While creating a new InnoDB segment, allocates the extent
before allocating the inode or page allocation even though
the pages are present in fragment segment. This patch does
reserve the extent when InnoDB ran out of fragment pages
in the tablespace.
Let simplify the test.
The update_time is stored in the table metadata (dict_table_t);
it has nothing to do with buffer pool page eviction or replacement.
prepare_inplace_add_virtual(): Over-estimate the size of the arrays
by not subtracting table->s->virtual_fields (which may refer to
stored, not virtual generated columns). InnoDB only distinguishes
virtual columns.
dict_load_foreigns(): Use a correctly sized buffer for the maximum-length
SYS_FOREIGN.ID. In case of overflow, do not crash the server but instead
return DB_CORRUPTION.
ha_innobase::check_if_supported_inplace_alter(): Refuse to change the
collation of a column that would become or remain indexed as part of
the ALTER TABLE operation.
In MariaDB Server 10.6, we will allow this type of operation;
that fix depends on MDEV-15250.
Starting with 10.5, InnoDB crash recovery tests seem to time out
more easily under Valgrind, which emulates multiple threads by
interleaving them in a single operating system thread.
These tests will still be covered by
AddressSanitizer and MemorySanitizer.
- In case of discarded tablespace, InnoDB can't read the root page to
assign the n_core_null_bytes. Consecutive instant DDL fails because
of non-matching n_core_null_bytes.
prepare_inplace_alter_table_dict(): If the table will not be rebuilt,
preserve all of the original ROW_FORMAT, including the compressed
page size flags related to ROW_FORMAT=COMPRESSED.
We do not really care about the exact result; we only care that the
statistics will be accessed. The result could change depending on
when some statistics were updated in the background or when some
committed delete-marked rows were purged from other tables on
which persistent statistics are enabled.
The counters were added in commit 5e55d1ced5
and any code to update them was
inadvertently removed in commit 2e814d4702
when applying InnoDB changes from MySQL 5.7.
Let us remove these counters that never reported anything useful. If such
statistics are really needed in a special case, they can be obtained by
instrumenting the code by some means, such as eBPF or a source code patch.
btr_insert_into_right_sibling(): Inherit any gap lock from the
left sibling to the right sibling before inserting the record
to the right sibling and updating the node pointer(s).
lock_update_node_pointer(): Update locks in case a node pointer
will move.
Based on mysql/mysql-server@c7d93c274f
It suffices to test compression with one record. Restarting the
server is not really needed; we are exercising the log based recovery
in other tests, such as mariabackup.page_compression_level.
This is a backport of commit 4489a89c71
in order to remove the test innodb.redo_log_during_checkpoint
that would cause trouble in the DBUG subsystem invoked by
safe_mutex_lock() via log_checkpoint(). Before
commit 7cffb5f6e8
these mutexes were of different type.
The following options were introduced in
commit 2e814d4702 (mariadb-10.2.2)
and have little use:
innodb_disable_resize_buffer_pool_debug had no effect even in
MariaDB 10.2.2 or MySQL 5.7.9. It was introduced in
mysql/mysql-server@5c4094cf49
to work around a problem that was fixed in
mysql/mysql-server@2957ae4f99
(but the parameter was not removed).
innodb_page_cleaner_disabled_debug and innodb_master_thread_disabled_debug
are only used by the test innodb.redo_log_during_checkpoint
that will be removed as part of this commit.
innodb_dict_stats_disabled_debug is only used by that test,
and it is redundant because one could simply use
innodb_stats_persistent=OFF or the STATS_PERSISTENT=0 attribute
of the table in the test to achieve the same effect.
