The bug only affects ROW_FORMAT=DYNAMIC tables.
It is reproducible already with 2 records in the table.
Keep testing with ROW_FORMAT=REDUNDANT just in case.

| | | | |
| | | |
| | | |

The bug only affected innodb_page_size=64k. There is no point
running the test with smaller page sizes.

The files ibtmp1 and ib_buffer_pool are sometimes created, sometimes not.
Remove them if they exist.

For running the Galera tests, the variable my_disable_leak_check
was set to true in order to avoid assertions due to memory leaks
at shutdown.
Some adjustments due to MDEV-13625 (merge InnoDB tests from MySQL 5.6)
were performed. The most notable behaviour changes from 10.0 and 10.1
are the following:
* innodb.innodb-table-online: adjustments for the DROP COLUMN
behaviour change (MDEV-11114, MDEV-13613)
* innodb.innodb-index-online-fk: the removal of a (1,NULL) record
from the result; originally removed in MySQL 5.7 in the
Oracle Bug #16244691 fix
https://github.com/mysql/mysql-server/commit/377774689bf6a16af74182753fe950d514c2c6dd
* innodb.create-index-debug: disabled due to MDEV-13680
(the MySQL Bug #77497 fix was not merged from 5.6 to 5.7.10)
* innodb.innodb-alter-autoinc: MariaDB 10.2 behaves like MySQL 5.6/5.7,
while MariaDB 10.0 and 10.1 assign different values when
auto_increment_increment or auto_increment_offset are used.
Also MySQL 5.6/5.7 exhibit different behaviour between
LGORITHM=INPLACE and ALGORITHM=COPY, so something needs to be tested
and fixed in both MariaDB 10.0 and 10.2.
* innodb.innodb-wl5980-alter: disabled because it would trigger an
InnoDB assertion failure (MDEV-13668 may need additional effort in 10.2)

When MySQL 5.0.3 introduced InnoDB support for two-phase commit,
it also introduced the questionable logic to roll back XA PREPARE
transactions on startup when innodb_force_recovery is 1 or 2.
Remove this logic in order to avoid unwanted side effects when
innodb_force_recovery is being set for other reasons. That is,
XA PREPARE transactions will always remain in that state until
InnoDB receives an explicit XA ROLLBACK or XA COMMIT request
from the upper layer.
At the time the logic was introduced in MySQL 5.0.3, there already
was a startup parameter that is the preferred way of achieving
the behaviour: --tc-heuristic-recover=ROLLBACK.

In the test, SET GLOBAL innodb_purge_rseg_truncate_frequency = 1
in order to ensure that everything is purged in the slow shutdown.
This could be viewed as a flaw of the slow shutdown.

on node pointer pages
This bug was a regression caused by MDEV-12698.
On non-leaf pages, the delete-mark flag in the node pointer records is
basically garbage. (Delete-marking only makes sense at the leaf level
anyway. The purpose of the delete-mark is to tell MVCC, locking and purge
that a leaf-level record does not exist in the READ UNCOMMITTED view,
but it used to exist.)
Node pointer records and non-leaf pages are glue that attaches multiple
leaf pages to an index. This glue is supposed to be transparent to the
transactional layer.
When a page is split, InnoDB creates a node pointer record out of the
child page record that the cursor is positioned on. The node pointer record
for the parent page will be a copy of the child page record, amended with
the child page number. If the child page record happened to carry the
delete-mark flag, then the node pointer record would also carry this flag
(even though the flag makes no sense outside child pages).
(On a related note, for the first node pointer record in the first
node pointer page of each tree level, if the MIN_REC_FLAG is set,
the rest of the record contents (except the child page number)
is basically garbage. From this garbage you could deduce at which point
the child was originally split.)
page_scan_method_t: Replace with bool, as there are only 2 values.
dict_stats_scan_page(): Replace the parameter scan_method with is_leaf.
Ignore the bogus (garbage) delete-mark flag if !is_leaf.

The parameter --innodb-sync-debug, which is disabled by default,
aims to find potential deadlocks in InnoDB.
When the parameter is enabled, lots of tests failed. Most of these
failures were due to bogus diagnostics. But, as part of this fix,
we are also fixing a bug in error handling code and removing dead
code, and fixing cases where an uninitialized mutex was being
locked and unlocked.
dict_create_foreign_constraints_low(): Remove an extraneous
mutex_exit() call that could cause corruption in an error handling
path. Also, do not unnecessarily acquire dict_foreign_err_mutex.
Its only purpose is to control concurrent access to
dict_foreign_err_file.
row_ins_foreign_trx_print(): Replace a redundant condition with a
debug assertion.
srv_dict_tmpfile, srv_dict_tmpfile_mutex: Remove. The
temporary file is never being written to or read from.
log_free_check(): Allow SYNC_FTS_CACHE (fts_cache_t::lock)
to be held.
ha_innobase::inplace_alter_table(), row_merge_insert_index_tuples():
Assert that no unexpected latches are being held.
sync_latch_meta_init(): Properly initialize dict_operation_lock_key
at SYNC_DICT_OPERATION. dict_sys->mutex is SYNC_DICT, and
the now-removed SRV_DICT_TMPFILE was wrongly registered at
SYNC_DICT_OPERATION.
buf_block_init(): Correctly register buf_block_t::debug_latch.
It was previously misleadingly reported as LATCH_ID_DICT_FOREIGN_ERR.
latch_level_t: Correct the relative latching order of
SYNC_IBUF_PESS_INSERT_MUTEX,SYNC_INDEX_TREE and
SYNC_FILE_FORMAT_TAG,SYNC_DICT_OPERATION to avoid bogus failures.
row_drop_table_for_mysql(): Avoid accessing btr_defragment_mutex
if the defragmentation thread has not been started. This is the
case during fts_drop_orphaned_tables() in recv_recovery_rollback_active().
fil_space_destroy_crypt_data(): Avoid acquiring fil_crypt_threads_mutex
when it is uninitialized. We may have created crypt_data before the
mutex was created, and the mutex creation would be skipped if
InnoDB startup failed or --innodb-read-only was specified.

code refactoring on innochecksum.
Added page0size.h include from 10.2 to make 10.1 vrs 10.2 innochecksum
as identical as possible.

Crashes with innodb_page_size=64K. Does not crash at <= 32K.
Problem was that when blob record that was earlier < 16k is
enlarged at update wo that length > 16K it should be stored
externally. However, that was not enforced when page-size = 64K
(note that 16K+1 < 64K/2 i.e. half of the btree leaf page).
btr_cur_optimistic_update: limit max record size to 16K
or in REDUNDANT row format to 16K-1.

longer than 16383 bytes
In all InnoDB row formats, the pointers or lengths stored in the record
header can be at most 14 bits, that is, count up to 16383.
In ROW_FORMAT=REDUNDANT, this limits the maximum possible record length
to 16383 bytes. In other ROW_FORMAT, it could merely limit the maximum
length of variable-length fields.
When MySQL 5.7 introduced innodb_page_size=32k and 64k, the maximum
record length was limited to 16383 bytes (I hope 16383, not 16384,
to be able to distinguish from a record whose length is 0 bytes).
This change is present in MariaDB Server 10.2.
btr_cur_optimistic_update(): Restrict maximum record size to 16K-1
for REDUNDANT and 64K page size.
dict_index_too_big_for_tree(): The maximum allowed record size
is half a B-tree page or 16K(-1 for REDUNDANT) for 64K page size.
convert_error_code_to_mysql(): Fix error message to print
correct limits.
my_error_innodb(): Fix error message to print correct limits.
page_zip_rec_needs_ext() : record size was already restricted to 16K.
Restrict REDUNDANT to 16K-1.
rem0rec.h: Introduce REDUNDANT_REC_MAX_DATA_SIZE (16K-1)
and COMPRESSED_REC_MAX_DATA_SIZE (16K).

upgrade from 10.1.20
When using innodb_page_size=16k, InnoDB tables
that were created in MariaDB 10.1.0 to 10.1.20 with
PAGE_COMPRESSED=1 and
PAGE_COMPRESSION_LEVEL=2 or PAGE_COMPRESSION_LEVEL=3
would fail to load.
fsp_flags_is_valid(): When using innodb_page_size=16k, use a
more strict check for .ibd files, with the assumption that
nobody would try to use different-page-size files.

MDEV-13498 is a performance regression that was introduced in MariaDB 10.2.2
by commit fec844aca88e1c6b9c36bb0b811e92d9d023ffb9
which introduced some Galera-specific conditions that were being
evaluated even if the write-set replication was not enabled.
MDEV-13246 Stale rows despite ON DELETE CASCADE constraint
is a correctness regression that was introduced by the same commit.
Especially the subcondition
!(parent && que_node_get_type(parent) == QUE_NODE_UPDATE)
which is equivalent to
!parent || que_node_get_type(parent) != QUE_NODE_UPDATE
makes little sense. If parent==NULL, the evaluation would proceed to the
std::find() expression, which would dereference parent. Because no SIGSEGV
was observed related to this, we can conclude that parent!=NULL always
holds. But then, the condition would be equivalent to
que_node_get_type(parent) != QUE_NODE_UPDATE
which would not make sense either, because the std::find() expression
is actually assuming the opposite when casting parent to upd_node_t*.
It looks like this condition never worked properly, or that
it was never properly tested, or both.
wsrep_must_process_fk(): Helper function to check if FOREIGN KEY
constraints need to be processed. Only evaluate the costly std::find()
expression when write-set replication is enabled.
Also, rely on operator<<(std::ostream&, const id_name_t&) and
operator<<(std::ostream&, const table_name_t&) for pretty-printing
index and table names.
row_upd_sec_index_entry(): Add !wsrep_thd_is_BF() to the condition.
This is applying part of "Galera MW-369 FK fixes"
https://github.com/codership/mysql-wsrep/commit/f37b79c6dab101310a45a9e8cb23c0f98716da52
that is described by the following part of the commit comment:
additionally: skipping wsrep_row_upd_check_foreign_constraint if thd has
BF, essentially is applier or replaying
This FK check would be needed only for populating parent row FK keys
in write set, so no use for appliers

trx_set_rw_mode(): Check the flag high_level_read_only instead
of testing srv_force_recovery (innodb_force_recovery) directly.
There is no need to prevent the creation of read-write transactions
if innodb_force_recovery=3 is used. Yes, in that mode any recovered
incomplete transactions will not be rolled back, but these transactions
will continue to hold locks on the records that they have modified.
If the new read-write transactions hit conflicts with already existing
(possibly recovered) transactions, the lock wait timeout mechanism
will work just fine.

With MDEV-12288 and MDEV-13536, the InnoDB purge threads will access
pages more often, causing all sorts of debug assertion failures in
the B-tree code.
Work around this problem by amending the corruption tests with
--innodb-purge-rseg-truncate-frequency=1 --skip-innodb-fast-shutdown
so that everything will be purged before the server
is restarted to deal with the corruption.

This should have been part of MDEV-12288.
trx_undo_t::del_marks: Remove.
Purge needs to process all undo log records in order to
reset the DB_TRX_ID. Before MDEV-12288, it sufficed to only delete
the purgeable delete-marked records, and it ignore other undo log.
trx_rseg_t::needs_purge: Renamed from trx_rseg_t::last_del_marks.
Indicates whether a rollback segment needs to be processed by purge.
TRX_UNDO_NEEDS_PURGE: Renamed from TRX_UNDO_DEL_MARKS.
Indicates whether a rollback segment needs to be processed by purge.
This will be 1 until trx_purge_free_segment() has been invoked.
row_purge_record_func(): Set the is_insert flag for TRX_UNDO_INSERT_REC,
so that the DB_ROLL_PTR will match in row_purge_reset_trx_id().
trx_purge_fetch_next_rec(): Add a comment about row_purge_record_func()
going to set the is_insert flag.
trx_purge_read_undo_rec(): Always attempt to read the undo log record.
trx_purge_get_next_rec(): Do not skip any undo log records.
Even when no clustered index record is going to be removed,
we may want to reset some DB_TRX_ID,DB_ROLL_PTR.
trx_undo_rec_get_cmpl_info(), trx_undo_rec_get_extern_storage(): Remove.
trx_purge_add_undo_to_history(): Set the TRX_UNDO_NEEDS_PURGE flag
so that the resetting will work on undo logs that were originally
created before MDEV-12288 (MariaDB 10.3.1).
trx_undo_roll_ptr_is_insert(), trx_purge_free_segment(): Cleanup
(should be no functional change).

Bug #25189192 ERRORS WHEN RESTARTING MYSQL AFTER RENAME TABLE.
PROBLEM
While renaming table innodb doesn't update the InnoDB Dictionary table
INNODB_SYS_DATAFILES incase there is change in database while doing
rename table. Hence on a restart the server log shows error that it
couldnt find table with old path before rename which has actually been
renamed. So the errors would only vanish if we update the system
tablespace
FIX
Update the innodb dictionary table with new path in the case there is
not a change in the table but the database holding the table as well.

The redo log format will be changed by MDEV-12288, and it could
be changed further during MariaDB 10.3 development. We will
allow startup from a clean redo log from any earlier InnoDB
version (up to MySQL 5.7 or MariaDB 10.3), but we will refuse
to do crash recovery from older-format redo logs.
recv_log_format_0_recover(): Remove a reference to MySQL documentation,
which may be misleading when it comes to MariaDB.
recv_log_recover_10_2(): Check if a MariaDB 10.2.2/MySQL 5.7.9
redo log is clean.
recv_find_max_checkpoint(): Invoke recv_log_recover_10_2() if the
redo log is in the MariaDB 10.2.2 or MySQL 5.7.9 format.

On Windows, when tmpdir is not writable, there are only messages
like this:
2017-07-05 14:04:25 3860 [ERROR] InnoDB: Unable to create temporary file; errno: 0
On other platforms, there would be two messages for each failure:
2017-07-05 17:23:02 140436573771648 [ERROR] mysqld: Can't create/write to file '/dev/null/nonexistent/ibaajU4U' (Errcode: 20 "Not a directory")
2017-07-05 17:23:02 140436573771648 [ERROR] InnoDB: Unable to create temporary file; errno: 20
