ha_innobase::defragment_table(): Skip corrupted indexes and
FULLTEXT INDEX. In InnoDB, FULLTEXT INDEX is implemented with
auxiliary tables. We will not defragment them on OPTIMIZE TABLE.
The test was unnecessarily depending on InnoDB purge, which can
sometimes fail to proceed.
Let us rewrite the test to use BEGIN;INSERT;ROLLBACK to cause the
immediate removal of the desired records.
The test is not expected to crash. With a non-debug server,
Valgrind completes in reasonable time without any failure.
Also, it does not make sense to store and restore parameters
when the parameters are already being restored by a server restart.
MDEV-11581: Mariadb starts InnoDB encryption threads
when key has not changed or data scrubbing turned off
Background: Key rotation is based on background threads
(innodb-encryption-threads) periodically going through
all tablespaces on fil_system. For each tablespace
current used key version is compared to max key age
(innodb-encryption-rotate-key-age). This process
naturally takes CPU. Similarly, in same time need for
scrubbing is investigated. Currently, key rotation
is fully supported on Amazon AWS key management plugin
only but InnoDB does not have knowledge what key
management plugin is used.
This patch re-purposes innodb-encryption-rotate-key-age=0
to disable key rotation and background data scrubbing.
All new tables are added to special list for key rotation
and key rotation is based on sending a event to
background encryption threads instead of using periodic
checking (i.e. timeout).
fil0fil.cc: Added functions fil_space_acquire_low()
to acquire a tablespace when it could be dropped concurrently.
This function is used from fil_space_acquire() or
fil_space_acquire_silent() that will not print
any messages if we try to acquire space that does not exist.
fil_space_release() to release a acquired tablespace.
fil_space_next() to iterate tablespaces in fil_system
using fil_space_acquire() and fil_space_release().
Similarly, fil_space_keyrotation_next() to iterate new
list fil_system->rotation_list where new tables.
are added if key rotation is disabled.
Removed unnecessary functions fil_get_first_space_safe()
fil_get_next_space_safe()
fil_node_open_file(): After page 0 is read read also
crypt_info if it is not yet read.
btr_scrub_lock_dict_func()
buf_page_check_corrupt()
buf_page_encrypt_before_write()
buf_merge_or_delete_for_page()
lock_print_info_all_transactions()
row_fts_psort_info_init()
row_truncate_table_for_mysql()
row_drop_table_for_mysql()
Use fil_space_acquire()/release() to access fil_space_t.
buf_page_decrypt_after_read():
Use fil_space_get_crypt_data() because at this point
we might not yet have read page 0.
fil0crypt.cc/fil0fil.h: Lot of changes. Pass fil_space_t* directly
to functions needing it and store fil_space_t* to rotation state.
Use fil_space_acquire()/release() when iterating tablespaces
and removed unnecessary is_closing from fil_crypt_t. Use
fil_space_t::is_stopping() to detect when access to
tablespace should be stopped. Removed unnecessary
fil_space_get_crypt_data().
fil_space_create(): Inform key rotation that there could
be something to do if key rotation is disabled and new
table with encryption enabled is created.
Remove unnecessary functions fil_get_first_space_safe()
and fil_get_next_space_safe(). fil_space_acquire()
and fil_space_release() are used instead. Moved
fil_space_get_crypt_data() and fil_space_set_crypt_data()
to fil0crypt.cc.
fsp_header_init(): Acquire fil_space_t*, write crypt_data
and release space.
check_table_options()
Renamed FIL_SPACE_ENCRYPTION_* TO FIL_ENCRYPTION_*
i_s.cc: Added ROTATING_OR_FLUSHING field to
information_schema.innodb_tablespace_encryption
to show current status of key rotation.
Make SELECT <columns> FROM I_S.TABLES behave identically independently
from whether <columns> require opening the table in engine or
<columns> can be filled with only opening the frm.
In particular, fill_schema_table_from_frm() should not silently skip
frms with unknown engine, but should fill the I_S.TABLES row
with NULLs just like fill_schema_table_by_open() does.
Also, implement MDEV-11027 a little differently from 5.5 and 10.0:
recv_apply_hashed_log_recs(): Change the return type back to void
(DB_SUCCESS was always returned).
Report progress also via systemd using sd_notifyf().
Also, implement MDEV-11027 a little differently from 5.5:
recv_sys_t::report(ib_time_t): Determine whether progress should
be reported.
recv_apply_hashed_log_recs(): Rename the parameter to last_batch.
Revoked executable bit from files that are not supposed to be executed directly.
Removed interpreted from files that are not supposed to be executed directly.
Added interpreter to files that are supposed to be executed directly.
my_readline can fail due to missing file. Make my_readline report this
condition separately so that we can catch it and report an appropriate
error message to the user.
This is an addition to original fix. Buildbot revealed another sporadic failure
in perfschema.threads_mysql test. Tests relies on data stored in
performance_schema.threads, while performing waits on
information_schema.processlist. These tables are not updated synchronously.
Fixed by performing waits on performance_schema.threads instead.
TOCTOU bug. The path is checked to be valid, symlinks are resolved.
Then the resolved path is opened. Between the check and the open,
there's a window when one can replace some path component with a
symlink, bypassing validity checks.
Fix: after we resolved all symlinks in the path, don't allow open()
to resolve symlinks, there should be none.
Compared to the old MyISAM/Aria code:
* fastpath. Opening of not-symlinked files is just one open(),
no fn_format() and lstat() anymore.
* opening of symlinked tables doesn't do fn_format() and lstat() either.
it also doesn't to realpath() (which was lstat-ing every path
component), instead if opens every path component with O_PATH.
* share->data_file_name stores realpath(path) not readlink(path). So,
SHOW CREATE TABLE needs to do lstat/readlink() now (see ::info()),
and certain error messages (cannot open file "XXX") show the real
file path with all symlinks resolved.
Workaround for join_cache + index on vcols + keyread bug.
Initialize the record to avoid caching garbage in non-read fields.
A proper fix (do not cache non-read fields at all) is done in 10.2
in commits 5d7607f340f..8d99166c697
The failure happens due to a race condition between processing
a row event (INSERT) and an automatically generated event
DROP TEMPORARY TABLE. Even though DROP has a higher GTID, it can
become visible in @@gtid_slave_pos before the row event with
a lower GTID has been committed. Since the test makes the slave
to synchronize with the master using GTID, the waiting stops
as soon as GTID of the DROP TEMPORARY TABLE becomes visible,
and if changes from the previous event haven't been applied yet,
the error occurs.
According to Kristian (see the comment to MDEV-10631), the real
problem is that DROP TEMPORARY TABLE is logged in the row mode
at all. For this particular test, since DROP does not do anything,
nothing prevents it from competing with the prior transaction.
The workaround for the test is to add a meaningful event
after DROP TEMPORARY TABLE, so that the slave would wait on its
GTID instead of the one from DROP.
Additionally (unrelated to this problem) removed FLUSH TABLES,
which, as the comment stated, should have been removed after
MDEV-6403 was fixed.
parts.partition_float_myisam, parts.partition_int_myisam,
parts.partition_float_innodb are all known to fail with timeouts
on slow builders. The tests are composed of several independent parts
for corresponding subtypes (float == float + double,
int == tinyint + smallint + mediumint + int + bigint). The solution
is to split them into separate tests. No test logic has been changed.
On a slow builder, a delay between binlog events on master could
occur, which would cause a heartbeat which is not expected by the
test. The solution is to monitor the timing of binlog events
on the master and only perform the heartbeat check if no critical
delays have happened.
Additionally, an unused variable was removed (this change is
unrelated to the bugfix).
buf_page_is_checksum_valid_crc32()
buf_page_is_checksum_valid_innodb()
buf_page_is_checksum_valid_none():
Use ULINTPF instead of %lu and %u for ib_uint32_t
fil_space_verify_crypt_checksum():
Check that page is really empty if checksum and
LSN are zero.
fil_space_verify_crypt_checksum():
Correct the comment to be more agurate.
buf0buf.h:
Remove unnecessary is_corrupt variable from
buf_page_t structure.
Use include/kill_and_restart_mysqld.inc instead of triggering
DBUG_SUICIDE() with debug instrumentation. In this way, more tests
can be run with --valgrind or on non-debug servers.
