This change add WITH_ROCKSDB_{LZ4,BZIP2,ZSTD,snappy} CMake variables
that can be set to ON/OFF/AUTO.
If variable has default value AUTO, rocksdb links with corresponding
compression library. OFF disables compiling/linking with specific compression
library, ON forces compiling with it (cmake would throw error if library
is not available)
Support for ZLIB is added unconditionally, as it is always there.
in Item_partition_func_safe_string(THD *thd, const char *name_arg,
uint length, CHARSET_INFO *cs= NULL), the 'name_arg' is the value
of the string constant and 'length' is the length of this constant,
so length == strlen(name_arg).
A proper InnoDB shutdown after aborted startup was introduced
in commit 81b7fe9d38.
Also related to this is MDEV-11985, making read-only shutdown more robust.
If startup was aborted, there may exist recovered transactions that were
not rolled back. Relax the assertions accordingly.
recv_writer_thread(): Do not assign recv_writer_thread_active=true
in order to avoid a race condition with
recv_recovery_from_checkpoint_finish().
recv_init_crash_recovery_spaces(): Assign recv_writer_thread_active=true
before creating recv_writer_thread.
Before killing the server, ensure that the redo log for the
incomplete transaction is flushed, so that the AUTO_INCREMENT
sequence will always be updated. Usually the INSERT
transaction would not have persisted the sequence before the
server was killed, but sometimes it could happen, causing
result mismatch.
Note: This test used to be called innodb_fts.innodb_fts_misc_debug.
Do not effectively set DEBUG_DBUG='d' by setting DEBUG_DBUG='-d,...'.
Instead, restore the saved value of DEBUG_DBUG.
Also, split the test innodb_fts.innodb_fts_misc_debug into
innodb_fts.crash_recovery and innodb_fts.misc_debug, and enable
these tests for --valgrind, the latter test for --embedded,
and the former tests for the non-debug server.
Encryption stores used key_version to
FIL_PAGE_FILE_FLUSH_LSN_OR_KEY_VERSION (offset 26)
field. Spatial indexes store RTREE Split Sequence Number
(FIL_RTREE_SPLIT_SEQ_NUM) in the same field. Both values
can't be stored in same field. Thus, current encryption
implementation does not support encrypting spatial indexes.
fil_space_encrypt(): Do not encrypt page if page type is
FIL_PAGE_RTREE (this is required for background
encryption innodb-encrypt-tables=ON).
create_table_info_t::check_table_options() Do not allow creating
table with ENCRYPTED=YES if table contains spatial index.
recv_log_format_0_recover(): Invoke log_decrypt_after_read() after
reading the old-format redo log buffer.
With this change, we will upgrade to an encrypted redo log that
is misleadingly carrying a MySQL 5.7.9 compatible format tag while
the log blocks (other than the header and the checkpoint blocks)
are in an incompatible, encrypted format.
That needs to be fixed by introducing a new redo log format tag that
indicates that the entire redo log is encrypted.
LOG_CHECKPOINT_ARRAY_END, LOG_CHECKPOINT_SIZE: Remove.
Change some error messages to refer to MariaDB 10.2.2 instead of
MySQL 5.7.9.
recv_find_max_checkpoint_0(): Do not abort when decrypting one of the
checkpoint pages fails.
after failed ADD UNIQUE INDEX
check_col_exists_in_indexes(): Add the parameter only_committed.
When considering committed indexes, evaluate index->is_committed().
Else, evaluate index->to_be_dropped.
rollback_inplace_alter_table(): Invoke check_col_exists_in_indexes()
with only_committed=true.
Galera disallow-writes feature was lost in InnoDB 5.7 merge
to 10.2. This patch restores this feature and fixes test
failure on test galera.galera_var_innodb_disallow_writes.
This patch complements the patch for bug 11138.
Without this patch some table-less queries with window functions
could cause crashes due to a memory overwrite.

Add cardinality stats to information schema
Summary: This adds cardinality stats to the INFORMATION_SCHEMA.ROCKSDB_INDEX_FILE_MAP table. This is the only missing user collected properties from SST files that we don't expose, which is useful for debugging cardinality bugs.

If InnoDB is started in innodb_read_only mode such that
recovered incomplete transactions exist at startup
(but the redo logs are clean), an assertion will fail at shutdown,
because there would exist some non-prepared transactions.
logs_empty_and_mark_files_at_shutdown(): Do not wait for incomplete
transactions to finish if innodb_read_only or innodb_force_recovery>=3.
Wait for purge to finish in only one place.
trx_sys_close(): Relax the assertion that would fail first.
trx_free_prepared(): Also free recovered TRX_STATE_ACTIVE transactions
if innodb_read_only or innodb_force_recovery>=3.
Also, revert my earlier fix to MySQL 5.7 because this fix is more generic:
Bug#20874411 INNODB SHUTDOWN HANGS IF INNODB_FORCE_RECOVERY>=3
SKIPPED ANY ROLLBACK
trx_undo_fake_prepared(): Remove.
trx_sys_any_active_transactions(): Revert the changes.
Rewrite the test so that the main server is restarted, instead of
--exec $MYSQLD_CMD. In this way, the test can be run with Valgrind
and with any --mysqld=--innodb-page-size.
Also remove the workaround --skip-innodb-use-native-aio. It should
not be needed when we are inheriting the server parameters from
the test environment.
Datafile::validate_for_recovery(): Remove a redundant error message.
An error is already reported by Datafile::open_read_write() if the
file cannot be opened.
Also, do not assign SEARCH_ABORT, so that the full test will be executed
even if one step fails.
The method Item_sum::print did not print opening '(' after the name
of simple window functions (like rank, dense_rank etc).
As a result the view definitions with such window functions
were formed invalid in .frm files.
srv_release_threads(): Actually wait for the threads to resume
from suspension. On CentOS 5 and possibly other platforms,
os_event_set() may be lost.
srv_resume_thread(): A counterpart of srv_suspend_thread().
Optionally wait for the event to be set, optionally with a timeout,
and then release the thread from suspension.
srv_free_slot(): Unconditionally suspend the thread. It is always
in resumed state when this function is entered.
srv_active_wake_master_thread_low(): Only call os_event_set().
srv_purge_coordinator_suspend(): Use srv_resume_thread() instead
of the complicated logic.
Test server startup with an empty encrypted redo log from 10.1.21.
FIXME: Pass the encryption parameters. Currently we only test startup
without properly set up encryption.
Using window functions over results of implicit groupings
required special handling in JOIN::make_aggr_tables_info.
The patch made sure that the result of implicit grouping
was written into a temporary table properly.
Remove the dependency on unzip. Instead, generate the InnoDB files
with perl.
log_block_checksum_is_ok(): Correct the error message.
recv_scan_log_recs(): Remove the duplicated error message for
log block checksum mismatch.
innobase_start_or_create_for_mysql(): If the server is in read-only
mode or if innodb_force_recovery>=3, do not try to modify the system
tablespace. (If the doublewrite buffer or the non-core system tables
do not exist, do not try to create them.)
innodb_shutdown(): Relax a debug assertion. If the system tablespace
did not contain a doublewrite buffer and if we started up in
innodb_read_only mode or with innodb_force_recovery>=3, it will not
be created.
dict_create_or_check_sys_tablespace(): Set the flag
srv_sys_tablespaces_open when the tables exist.
If a window function with aggregation is over the result
set of a grouping query then the argument of the aggregate
function from the window function is allowed to be an
aggregate function itself.
A GCM encrypted ciphertext must contain an authentication tag with AES_BLOCK_SIZE length, so we need to check that the length of ciphertext is at least AES_BLOCK_SIZE.
This fixes memory leaks in tests that cause InnoDB startup to fail.
buf_pool_free_instance(): Also free buf_pool->flush_rbt, which would
normally be freed when crash recovery finishes.
fil_node_close_file(), fil_space_free_low(), fil_close_all_files():
Relax some debug assertions to tolerate !srv_was_started.
innodb_shutdown(): Renamed from innobase_shutdown_for_mysql().
Changed the return type to void. Do not assume that all subsystems
were started.
que_init(), que_close(): Remove (empty functions).
srv_init(), srv_general_init(): Remove as global functions.
srv_free(): Allow srv_sys=NULL.
srv_get_active_thread_type(): Only return SRV_PURGE if purge really
is running.
srv_shutdown_all_bg_threads(): Do not reset srv_start_state. It will
be needed by innodb_shutdown().
innobase_start_or_create_for_mysql(): Always call srv_boot() so that
innodb_shutdown() can assume that it was called. Make more subsystems
dependent on SRV_START_STATE_STAT.
srv_shutdown_bg_undo_sources(): Require SRV_START_STATE_STAT.
trx_sys_close(): Do not assume purge_sys!=NULL. Do not call
buf_dblwr_free(), because the doublewrite buffer can exist while
the transaction system does not.
logs_empty_and_mark_files_at_shutdown(): Do a faster shutdown if
!srv_was_started.
recv_sys_close(): Invoke dblwr.pages.clear() which would normally
be invoked by buf_dblwr_process().
recv_recovery_from_checkpoint_start(): Always release log_sys->mutex.
row_mysql_close(): Allow the subsystem not to exist.
