- Do not throw output of exec command, if disable_result_log is set
save and dump it if exec fails. Need tha to meaningfully analyze
errors from mariabackup.
- rmdir now removes the entire tree. need that because xtrabackup tests
clean the whole directory.
- all filesystem modifying commands now require the argument to
be under MYSQLTEST_VARDIR or MYSQL_TMP_DIR.
Do not exporting mysqld entry points directly.
This is needed for mariabackup, to load encryption plugins on Windows.
All plugins are "pure" by default. To mark plugin "impure"
it should use RECOMPILE_FOR_EMBEDDED or STORAGE_ENGINE keyword.
because mysql->net.thd was reset to NULL in mysql_real_connect()
and thd_increment_bytes_received() didn't do anything.
Fix:
* set mysql->net.thd to current_thd instread.
* remove the test for non-null THD from a very often used
function thd_increment_bytes_received().
Problem was that bpage was referenced after it was already freed
from LRU. Fixed by adding a new variable encrypted that is
passed down to buf_page_check_corrupt() and used in
buf_page_get_gen() to stop processing page read.
This patch should also address following test failures and
bugs:
MDEV-12419: IMPORT should not look up tablespace in
PageConverter::validate(). This is now removed.
MDEV-10099: encryption.innodb_onlinealter_encryption fails
sporadically in buildbot
MDEV-11420: encryption.innodb_encryption-page-compression
failed in buildbot
MDEV-11222: encryption.encrypt_and_grep failed in buildbot on P8
Removed dict_table_t::is_encrypted and dict_table_t::ibd_file_missing
and replaced these with dict_table_t::file_unreadable. Table
ibd file is missing if fil_get_space(space_id) returns NULL
and encrypted if not. Removed dict_table_t::is_corrupted field.
Ported FilSpace class from 10.2 and using that on buf_page_check_corrupt(),
buf_page_decrypt_after_read(), buf_page_encrypt_before_write(),
buf_dblwr_process(), buf_read_page(), dict_stats_save_defrag_stats().
Added test cases when enrypted page could be read while doing
redo log crash recovery. Also added test case for row compressed
blobs.
btr_cur_open_at_index_side_func(),
btr_cur_open_at_rnd_pos_func(): Avoid referencing block that is
NULL.
buf_page_get_zip(): Issue error if page read fails.
buf_page_get_gen(): Use dberr_t for error detection and
do not reference bpage after we hare freed it.
buf_mark_space_corrupt(): remove bpage from LRU also when
it is encrypted.
buf_page_check_corrupt(): @return DB_SUCCESS if page has
been read and is not corrupted,
DB_PAGE_CORRUPTED if page based on checksum check is corrupted,
DB_DECRYPTION_FAILED if page post encryption checksum matches but
after decryption normal page checksum does not match. In read
case only DB_SUCCESS is possible.
buf_page_io_complete(): use dberr_t for error handling.
buf_flush_write_block_low(),
buf_read_ahead_random(),
buf_read_page_async(),
buf_read_ahead_linear(),
buf_read_ibuf_merge_pages(),
buf_read_recv_pages(),
fil_aio_wait():
Issue error if page read fails.
btr_pcur_move_to_next_page(): Do not reference page if it is
NULL.
Introduced dict_table_t::is_readable() and dict_index_t::is_readable()
that will return true if tablespace exists and pages read from
tablespace are not corrupted or page decryption failed.
Removed buf_page_t::key_version. After page decryption the
key version is not removed from page frame. For unencrypted
pages, old key_version is removed at buf_page_encrypt_before_write()
dict_stats_update_transient_for_index(),
dict_stats_update_transient()
Do not continue if table decryption failed or table
is corrupted.
dict0stats.cc: Introduced a dict_stats_report_error function
to avoid code duplication.
fil_parse_write_crypt_data():
Check that key read from redo log entry is found from
encryption plugin and if it is not, refuse to start.
PageConverter::validate(): Removed access to fil_space_t as
tablespace is not available during import.
Fixed error code on innodb.innodb test.
Merged test cased innodb-bad-key-change5 and innodb-bad-key-shutdown
to innodb-bad-key-change2. Removed innodb-bad-key-change5 test.
Decreased unnecessary complexity on some long lasting tests.
Removed fil_inc_pending_ops(), fil_decr_pending_ops(),
fil_get_first_space(), fil_get_next_space(),
fil_get_first_space_safe(), fil_get_next_space_safe()
functions.
fil_space_verify_crypt_checksum(): Fixed bug found using ASAN
where FIL_PAGE_END_LSN_OLD_CHECKSUM field was incorrectly
accessed from row compressed tables. Fixed out of page frame
bug for row compressed tables in
fil_space_verify_crypt_checksum() found using ASAN. Incorrect
function was called for compressed table.
Added new tests for discard, rename table and drop (we should allow them
even when page decryption fails). Alter table rename is not allowed.
Added test for restart with innodb-force-recovery=1 when page read on
redo-recovery cant be decrypted. Added test for corrupted table where
both page data and FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION is corrupted.
Adjusted the test case innodb_bug14147491 so that it does not anymore
expect crash. Instead table is just mostly not usable.
fil0fil.h: fil_space_acquire_low is not visible function
and fil_space_acquire and fil_space_acquire_silent are
inline functions. FilSpace class uses fil_space_acquire_low
directly.
recv_apply_hashed_log_recs() does not return anything.
The code that chooses between materialization of a non-correlated
IN subquery and its transformation into an EXISTS correlated
subquery assumes that the execution plan for the outer select
has been already built. However it was not always so if subqueries
occurred in the expressions used for ref access to tables of
the outer select. A call of the function create_ref_for_key() in
get_best_combination() could trigger a premature execution of
the above mentioned code when the execution plan structures for
the outer select were not fully built. This could cause a crash
of the server.
The fix postpones the calls of create_ref_for_key() until the
structures for the execution plan is fully built.
To fix OSX error:

The implementation of the walk method for the class Item_in_subselect
was missing. As a result the method never traversed the left operand
of any IN subquery predicate.
Item_exists_subselect::exists2in_processor() that performs the
Exist-To-In transformation calls the walk method to collect info
on outer references. As the walk method did not traverse the
left operands of the IN subqueries the outer references there
were not taken into account and some subqueries that were actually
correlated were marked as uncorrelated. It could lead to an
attempt of the materialization of such a subquery.
Also added a cleanup for some test cases merged from 5.5.
buf_flush_write_block_low(): Acquire the tablespace reference once,
and pass it to lower-level functions. This is only a start; further
calls may be removed later.
fil_crypt_thread(): Do invoke fil_crypt_complete_rotate_space()
when the tablespace is about to be dropped. Also, remove a redundant
check whether rotate_thread_t::space is NULL. It can only become
NULL when fil_crypt_find_space_to_rotate() returns false, and in
that case we would already have terminated the loop.
fil_crypt_find_page_to_rotate(): Remove a redundant check for
space->crypt_data == NULL. Once encryption metadata has been
created for a tablespace, it cannot be removed without dropping
the entire tablespace.
This reverts part of commit 50eb40a2a8
which backported the code from MariaDB 10.2. The XtraDB version of
the code included a ut_error statement (aborting the process) when
a tablespace is not found. Luckily this change was not part of a
release; MariaDB 10.1.22 had been released some days earlier.
This is a reduced version of an originally much larger patch.
We will keep the definition of the ulint, lint data types unchanged,
and we will not be replacing fprintf() calls with ib_logf().
On Windows, use the standard format strings instead of nonstandard
extensions.
This patch fixes some errors in format strings.
Most notably, an IMPORT TABLESPACE error message in InnoDB was
displaying the number of columns instead of the mismatching flags.
Allow 64-bit atomic operations on 32-bit systems,
only relying on HAVE_ATOMIC_BUILTINS_64, disregarding
the width of the register file.
Define UNIV_WORD_SIZE correctly on all systems, including Windows.
In MariaDB 10.0 and 10.1, it was incorrectly defined as 4 on
64-bit Windows.
Define HAVE_ATOMIC_BUILTINS_64 on Windows
(64-bit atomics are available on both 32-bit and 64-bit Windows
platforms; the operations were unnecessarily disabled even on
64-bit Windows).
MONITOR_OS_PENDING_READS, MONITOR_OS_PENDING_WRITES: Enable by default.
os_file_n_pending_preads, os_file_n_pending_pwrites,
os_n_pending_reads, os_n_pending_writes: Remove.
Use the monitor counters instead.
os_file_count_mutex: Remove. On a system that does not support
64-bit atomics, monitor_mutex will be used instead.
The motivation for this is that Perl is moving towards not having
current directory ./ in @INC by default. This is causing
mysql-test-run.pl to fail in latest Debian Unstable:
https://lists.debian.org/debian-devel-announce/2016/08/msg00013.html
However, we have `use "lib"`, there is no need for current directory
in @INC, except for a gross hack. In mtr_cases.pm, there is a
`require "mtr_misc.pl"`, which hides mtr_misc.pl away in mtr_cases
namespace. And things only work because mysql-test-run.pl loads it
with a different name, `require "lib/mtr_misc.pl"`! (Perl will
`require` only once for each unique filename).
Fix this by only using `require` in main program, and referencing
functions with :: scope from other namespaces. For multi-use in
different namespaces, proper `use` modules should be used.

Disable the output that was added in MDEV-6812 if log_warnings=2 or less.
Also, remove some redundant messages.
TODO: Implement MDEV-12512 to supercede MDEV-6812 and properly report
the progress of ALTER TABLE…ALGORITHM=INPLACE.
When master_use_gtid=no, the IO thread loads the slave GTID state from
the master during connect. This races with the SQL thread when
gtid_ignore_duplicates=1. If an event is in the relay log from before
the new connect and has not been applied yet, moving the slave
position causes the SQL thread to think that event should be skipped
due to gtid_ignore_duplicates=1.
This patch simply disables gtid_ignore_duplicates when not using GTID,
which seems to be what one would expect.
