- It is not enough to have and DeleteSymlinks actions because within the same installation some exes executables can be both added and removed, which needs both adding and removing some symlinks. Instead of CreateSymlinks, there is now FixSymlinks function, which goes through the list, and adds or removes the symlinks as needed. - Implemented rollback for symlink custom action. - Generate list of symlinks in C++ file, using CMake, rather than storing lists as MSI properties.

If a joined table is accessed by a full text index then now no range rowid filter can be used when accessing the records of this table. This bug was fixed by the patch for mdev-20056. This commit adds only a test case with a query using a full text index and a range condition for another index.

Revert part of commit 6cedb671 because it turns out to be theoretically impossible to parse a ROW_FORMAT=COMPACT or ROW_FORMAT=DYNAMIC metadata record where the variable-length fields in the PRIMARY KEY have been written as nonempty strings.

- Replace "class Repeat_count" with function call. There is no reason for this class to exists. More complex and more code than doing a function! In addition the code didn't match what the val() function was doing. Other things: - Fixed compiler failure in print_cached_tables_callback()

in row_search_idx_cond_check When usage of rowid filter is evaluated by the optimizer to join a table to the current partial join employing a certain index it should be checked that a key for at least the major component of this index can be constructed using values from the columns of the partial join.

As noted in commit abd45cdc a search with PAGE_CUR_GE may land on the supremum record on a leaf page that is not the rightmost leaf page. This could occur when all keys on the current page are smaller than the search key, and the smallest key on the successor page is larger than the search key. Hence, after a failed PAGE_CUR_GE search, assertions btr_pcur_is_after_last_in_tree() are bogus and should be replaced with btr_pcur_is_after_last_on_page().

Introduce memcpy_aligned<N>(), memcmp_aligned<N>(), memset_aligned<N>() and use them for accessing InnoDB page header fields that are known to be aligned. MY_ASSUME_ALIGNED(): Wrapper for the GCC/clang __builtin_assume_aligned(). Nothing similar seems to exist in Microsoft Visual Studio, and the C++20 std::assume_aligned is not available to us yet. Explicitly specified alignment guarantees allow compilers to generate faster code on platforms with strict alignment rules, instead of emitting calls to potentially unaligned memcpy(), memcmp(), or memset().

This particular assertion happened when shutting down Innodb IO.IO shutdown properly waits for all IOs to finish However there is a race condition - right after releasing last IO slot and before decrementing task count in group, pending_io_count will be 0, but tasks_running will be 1, leading to assertion. The fix is to make task_group destructor to wait for last running task to finish.

It was mistakenly used by tdc_start_shutdown() to make sure TABLE_SHARE gets evicted from table definition cache when it becomes unused. However same effect is achieved by resetting tdc_size and tc_size. Part of MDEV-17882 - Cleanup refresh version

After 7fb9d649 it is used only by ALTER/DROP SERVER, which most probably wasn't intentional as Federated never supported delayed inserts anyway. If delayed inserts will ever become an issue with ALTER/DROP SERVER, we should kill them by acquiring X-lock instead. Part of MDEV-17882 - Cleanup refresh version

It is never called after 7fb9d649, which makes the whole refresh version infrastructure useless. Removed: - tdc_version_t - TDC_VERSION_MAX - tdc_version - TDC_element::version - tdc_increment_refresh_version() - tdc_refresh_version() - refresh_version argument of tdc_wait_for_old_version() - Flush_commands status variable - refresh version from COM_STATISTICS - refresh version from dbug printouts Part of MDEV-17882 - Cleanup refresh version

dict_stats_shutdown() can hang, waiting for timer callback to finish. This happens because locks the same mutex, which can also used inside timer callback, within dict_stats_schedule() function. Fix is to make dict_stats_schedule() use mutex.try_lock() instead of mutex.lock(). In the unlikely case of simultaneous dict_stats_schedule() setting different timer delays, now the first one would win, which is fine. Important is that shutdown won't hang.

We must relax too strict debug assertions. For latin1_swedish_ci, mtype=DATA_CHAR or mtype=DATA_VARCHAR will be used instead of mtype=DATA_MYSQL or mtype=DATA_VARMYSQL. Likewise, some changes of dtype_get_charset_coll() do not affect the data type encoding, but only any indexes that are defined on the column. Charset::same_encoding(): Check whether two charset-collations have the same character set encoding. dict_col_t::same_encoding(): Check whether two character columns have the same character set encoding. dict_col_t::same_type(): Check whether two columns have a compatible data type encoding. dict_col_t::same_format(), dict_table_t::instant_column(): Do not compare mtype or the charset-collation of prtype directly. Rely on dict_col_t::same_type() instead. dtype_get_charset_coll(): Narrow the return type to uint16_t. This is a refined version of a fix that was developed by Thirunarayanan Balathandayuthapani.

The original crash happened when async replication IO thread was updating mysql.gtid_slave_pos table. Operations on this table should remain node local, but it appears that protection (THD::wsrep_ignore_table flag) to prevent wsrep replication for this table mas missing for innodb write_row() and update_row(). It was somewhat difficult to reproduce the issue, because mtr seems to create the affected table mysql.gtid_log_pos as of Aria engine type, and Aria engine operations will not be replicated anyhow. It looks, though, that in release installation, mysql.gtid_slave_pos table is of InnoDB engine. It was possible to trigger somewhat related problem by running test galera.galera_as_slave_gtid with configuration: gtid_pos_auto_engines=InnoDB. However, this test mode, causes earlier crash when replication background thread creates aditional table: mysql.gtid_slave_pos_InnoDB, and this table create triggered wsrep TOI replication, which also failed for assertion. Actually, async replication IO and background threads should not replicate anything to cluster. This pull request contains new test galera.galera_as_slave_gtid_auto_engine, which basically just runs galera.galera_as_slave_gtid with configuration of gtid_pos_auto_engines=InnoDB. Test galera.galera_as_slave_gtid is also modified for better code reuse. Actual fix for MDEV-21096 is in storage/innobase/handler/ha_innodb.cc, where THD::wsrep_ignore_table flag is now honored before wsrep key population. There is additional fix in sql/service_wsrep.cc where async replication IO and background threads are marked as non-local. This fences these threads out of wsrep replication altogether. Note that this change, actually makes the use of THD::wsrep_ignore-table redundant. We may want to refactor THD::wsrep_ignore_table out in the future, if there is no other use case for it in sight.

At each mini-transaction commit, the log sequence number of the mini-transaction must be written to each modified page, so that it will be available in the FIL_PAGE_LSN field when the page is being read in crash recovery. InnoDB was unnecessarily allocating redundant storage for the field, in buf_page_t::newest_modification. Let us access FIL_PAGE_LSN directly. Furthermore, on ALTER TABLE...IMPORT TABLESPACE, let us write 0 to FIL_PAGE_LSN instead of using log_sys.lsn. buf_flush_init_for_writing(), buf_flush_update_zip_checksum(), fil_encrypt_buf_for_full_crc32(), fil_encrypt_buf(), fil_space_encrypt(): Remove the parameter lsn. buf_page_get_newest_modification(): Merge with the only caller. buf_tmp_reserve_compression_buf(), buf_tmp_page_encrypt(), buf_page_encrypt(): Define static in the same compilation unit with the only caller. PageConverter::m_current_lsn: Remove. Write 0 to FIL_PAGE_LSN on ALTER TABLE...IMPORT TABLESPACE.

in row_search_idx_cond_check For a single table query with ORDER BY and several sargable range conditions the optimizer may choose an execution plan that employs a rowid filter. In this case it is important to build the filter before calling the function JOIN_TAB::sort_table() that creates sort index for the result set, because when this is index created the filter has to be already filled. After the sort index has been created the filter must be deactivated. If not to do this the innodb function row_search_idx_cond_check() is getting confused when it has to read rows from the created sort index by using ha_rnd_pos(). The order of actions mentioned above is needed also when processing a join query if sorting is performed for the first non constant table in the chosen execution plan.

Implement syntax like: create table t1 (x int) with system versioning partition by system_time; which will create 1 history partition and 1 current partition. Also it is possible to specify the number of history partitions: create table t1 (x int) with system versioning partition by system_time partitions 5; which will create 4 history partitions (and 1 current partition). Tests: partition.test cases are duplicated where it is appropriate for default partitions. partition_rotation.test cases are replaced by default partitions where possible.

Add support of referential constraints directly in column defininions: create table t1 (id1 int primary key); create table t2 (id2 int references t1(id1)); Referenced field name can be omitted if equal to foreign field name: create table t1 (id int primary key); create table t2 (id int references t1); Until 10.5 this syntax was understood by the parser but was silently ignored. In case of generated columns this syntax is disabled at parser level by ER_PARSE_ERROR. Note that separate FOREIGN KEY clause for generated columns is disabled at storage engine level.
