The XtraDB option innodb_track_changed_pages causes
the function log_group_read_log_seg() to be invoked
even when recv_sys==NULL, leading to the SIGSEGV.
This regression was caused by
MDEV-11027 InnoDB log recovery is too noisy
with recursive reference in subquery
If a recursive CTE uses a subquery with recursive reference then
the virtual function reset() must be called after each iteration
performed at the execution of the CTE.
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.
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).
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().
debug_key_management
encrypt_and_grep
innodb_encryption
If real table count is different from what is expected by the test, it
just hangs on waiting to fulfill hardcoded number. And then exits with
**failed** after 10 minutes of wait: quite unfriendly and hard to
figure out what's going on.
Fix and enable some of the tests; some remain disabled.
The tests innodb_gis.rtree_old and innodb_gis.row_format
duplicated some versions of the test main.gis-rtree.
Instead of duplicating, source that test, in a new test
innodb_gis.innodb_gis_rtree.
Introduce innodb_row_format.combinations. Due to this,
ROW_FORMAT=COMPRESSED will not be covered in some tests
where it is covered in MySQL 5.7.
The function rtr_update_mbr_field_in_place() is generating
MLOG_REC_UPDATE_IN_PLACE or MLOG_COMP_REC_UPDATE_IN_PLACE records
on non-leaf pages, even though MLOG_WRITE_STRING would perfectly
suffice for updating a fixed-length data field.
btr_cur_parse_update_in_place(): If flags==7, the record may be
from rtr_update_mbr_field_in_place(), and we must check if the
page is a leaf page. Otherwise, assume that it is.
btr_cur_update_in_place(): Assert that the page is a leaf page.
Other things, mainly to get
create_mysqld_error_find_printf_error tool to work:
- Added protection to not include mysqld_error.h twice
- Include "unireg.h" instead of "mysqld_error.h" in server
- Added protection if ER_XX messages are already defined
- Removed wrong calls to my_error(ER_OUTOFMEMORY) as
my_malloc() and my_alloc will do this automatically
- Added missing %s to ER_DUP_QUERY_NAME
- Removed old and wrong calls to my_strerror() when using
MY_ERROR_ON_RENAME (wrong merge)
- Fixed deadlock error message from Galera. Before the extra
information given to ER_LOCK_DEADLOCK was missing because
ER_LOCK_DEADLOCK doesn't provide any extra information.
I kept #ifdef mysqld_error_find_printf_error_used in sql_acl.h
to make it easy to do this kind of check again in the future
