This bug affected tables where the PRIMARY KEY contains variable-length
columns, and ROW_FORMAT is COMPACT or DYNAMIC.
rec_init_offsets_comp_ordinary(): Do not short-cut the parsing
of the record header for records that contain explicit values
for instantly added columns.
rec_copy_prefix_to_buf(): Copy more header for records that
contain explicit values for instantly added columns.
Many related changes.
Note that AS OF condition must always be pushed down to physical tables,
it cannot be applied to a derived or a view. Thus:
* no versioning for internal temporary tables, they can never store
historical data.
* remove special versioning code from mysql_derived_prepare and
remove ER_VERS_DERIVED_PROHIBITED - derived can have no historical
data and cannot be prohibited for system versioning related reasons.
* do not expand select list for derived/views with sys vers fields,
derived/views can never have historical data.
* remove special invisiblity rules for sys vers fields, they are no
longer needed after the previous change
* remove system_versioning_hide, it lost the meaning after the
previous change.
* remove ER_VERS_SYSTEM_TIME_CLASH, it's no "clash", the inner
AS OF clause always wins.
* non-versioned fields in a historical query
reword the warning text, downgrade to note, don't
replace values with NULLs
innodb/buf_LRU_get_free_block
Add debug instrumentation to produce error message about
no free pages. Print error message only once and do not
enable innodb monitor.
xtradb/buf_LRU_get_free_block
Add debug instrumentation to produce error message about
no free pages. Print error message only once and do not
enable innodb monitor. Remove code that does not seem to
be used.
innodb-lru-force-no-free-page.test
New test case to force produce desired error message.
in JOIN::inject_best_splitting_cond
The value of SplM_opt_info::last_plan should be set to NULL
before any search for a splitting plan for a splittable
materialized table.
dict_foreign_find_index(): Ignore incompletely created indexes.
After a failed ADD UNIQUE INDEX, an incompletely created index
could be left behind until the next ALTER TABLE statement.
rec_get_trx_id(): Because rec is not necessarily residing in
a buffer pool page (it could be an old version of a clustered index
record, allocated from heap), remove the debug assertions that
depend on page_align(rec).
There is a race condition on a test. con1 is the older transaction
as it query started wait first. Test continues so that con1 gets
lock wait timeout first. There is possibility that default connection
gets lock timeout also or as con1 is rolled back it gets the locks
it waited and does the update. Fixed by removing query outputs as
they could vary and accepting success from default connection
query.
This bug affects both writing and reading encrypted redo log in
MariaDB 10.1, starting from version 10.1.3 which added support for
innodb_encrypt_log. That is, InnoDB crash recovery and Mariabackup
will sometimes fail when innodb_encrypt_log is used.
MariaDB 10.2 or Mariabackup 10.2 or later versions are not affected.
log_block_get_start_lsn(): Remove. This function would cause trouble if
a log segment that is being read is crossing a 32-bit boundary of the LSN,
because this function does not allow the most significant 32 bits of the
LSN to change.
log_blocks_crypt(), log_encrypt_before_write(), log_decrypt_after_read():
Add the parameter "lsn" for the start LSN of the block.
log_blocks_encrypt(): Remove (unused function).
In case libaio is not found, and required,
remove variables HAVE_LIBAIO_H and HAVE_LIBAIO from cache, so that cmake
rerun after installation of libaio would succeed.
2cd3169113 broke conf_to_src,
because strings library is now dependend on mysys (my_alloc etc are used
now directly in string lib)
Fix by adding appropriate dependency.
Also exclude conf_to_src from VS IDE builds. EXCLUDE_FROM_ALL
is not enough for that.
If the specification of a CTE contains a reference to a temporary table
then THD::open_temporary_table() must be called for this reference for
any occurrence of the CTE in the query. By mistake this was done only
for the first occurrences of CTEs.
The patch fixes this problem in With_element::clone_parsed_spec().
It also moves there the call of check_dependencies_in_with_clauses()
to its proper place before the call of check_table_access().
Additionally the patch optimizes the number of calls of the
function check_dependencies_in_with_clauses().
