- This is a regression of commit b26e603aeb. While dropping
the incompletely created table, InnoDB shouldn't consider that operation as non-atomic one.
row_drop_table_for_mysql(): Avoid accessing non-existing dictionary tables.
dict_create_or_check_foreign_constraint_tables(): Add debug instrumentation
for creating and dropping a table before the creation of any non-core
dictionary tables.
trx_purge_add_update_undo_to_history(): Adjust a debug assertion, so that
it will not fail due to the test instrumentation.
When code from MySQL 5.7.9 was merged to MariaDB 10.2.2
in commit 2e814d4702
an assignment validate=true was inadvertently added to the function
dict_check_sys_tables().
This causes InnoDB to open every single .ibd file on startup, even
when no crash recovery was needed.
Simply removing the assignment would make some tests fail. We do the
best to retain almost the same level of inconsistency detection.
In the test innodb.table_flags, access to one of the tables will not
be blocked despite inconsistent flags.
dict_check_sys_tables(): Remove the problematic assignment, and skip
validation in normal startup.
dict_load_table_one(): If the .ibd file cannot be opened, mark the
table as corrupted and unreadable.
fil_node_open_file(): Validate FSP_SPACE_FLAGS with the expected
flags. If reading the tablespace fails, invalidate node->handle
instead of letting it remain stale. This bug was caught by a
fil_validate() assertion failure.
fsp_flags_try_adjust(): If the tablespace file is invalid, do nothing.
innodb.table_flags: Adjust the test case. Due to the MDEV-12873 fix
in 10.2, the corrupted flags for table test.td would be converted,
and a tablespace flag mismatch will occur when trying to open the file.
Cover innodb.table_flags with the new innodb_page_size.combinations
32k and 64k.
dict_sys_tables_type_validate(): Remove an assertion that made a
check in the function redundant. Remove the excessive output to
the error log, as the invalid SYS_TABLES.TYPE value is already being
output.
Add a test case for corrupting SYS_TABLES.TYPE,
and for ROW_FORMAT=REDUNDANT, the unused field SYS_TABLES.MIX_LEN
that must be ignored (InnoDB before MySQL 5.5 wrote uninitialized
garbage to this column).
MariaDB 10.0 appears to validate the SYS_TABLES.TYPE properly.
This is a test-only change.
