TABLE::mark_columns_needed_for_update(): use_all_columns() assigns
pointer of all_set into read_set and write_set, but this is not good
since all_set is changed later by
TABLE::mark_columns_used_by_index_no_reset().
Do column_bitmaps_signal() whenever we change read_set/write_set.
Constraint check is done on secondary index update.
F.ex. DELETE does row_upd_sec_index_entry() and checks constraints in
row_upd_check_references_constraints(). UPDATE is optimized for the
case when order is not changed (node->cmpl_info & UPD_NODE_NO_ORD_CHANGE)
and doesn't do row_upd_sec_index_entry(), so it doesn't check constraints.
Since for versioned DELETE we do UPDATE actually, but expect behaviour
of DELETE in terms of constraints, we should deny this optimization to
get constraints checked.
Fix wrong referenced table check when versioned DELETE inserts history in parent
table. Set check_ref to false in this case.
Removed unused dup_chk_only argument for row_ins_sec_index_entry() and
added check_ref argument.
MDEV-18057 fix was superseded by this fix and reverted.

Other fixes:
* Merged versioning.update2 into versioning.update;
* Removed test2 database and done individual drop instead.
btr_cur_pessimistic_delete(): code changed in a way that allows
to put more REC_INFO_MIN_REC_FLAG assertions inside btr_set_min_rec_mark().
Without that change tests innodb.innodb-table-online,
innodb.temp_table_savepoint and innodb_zip.prefix_index_liftedlimit fail.
Removed basically duplicated page_zip_validate() calls
which fails because of temporary(!) invariant violation.
That fixed innodb_zip.wl5522_debug_zip and
innodb_zip.prefix_index_liftedlimit
The bug affects MariaDB Server 10.3 or later, but it makes sense
to improve CHECK TABLE in earlier versions already.
page_validate(): Check REC_INFO_MIN_REC_FLAG in the records.
This allows CHECK TABLE to catch more bugs.
Until now, InnoDB inefficiently compared the aligned fields
FIL_PAGE_PREV, FIL_PAGE_NEXT to the byte-order-agnostic value FIL_NULL.
This is a backport of 32170f8c6d
from MariaDB Server 10.3.
fsp_free_seg_inode(): Remove the constant parameter log=true.
Only fsp_free_page() could also be called with log=false.
The dead code was introduced in
commit 304ae942f7
by me, and spotted by Thirunarayanan Balathandayuthapani.
Analysis
Mysqlbinlog output for encrypted binary log
#Q> insert into tab1 values (3,'row 003')
#190912 17:36:35 server id 10221 end_log_pos 980 CRC32 0x53bcb3d3 Table_map: `test`.`tab1` mapped to number 19
# at 940
#190912 17:36:35 server id 10221 end_log_pos 1026 CRC32 0xf2ae5136 Write_rows: table id 19 flags: STMT_END_F
Here we can see Table_map_log_event ends at 980 but Next event starts at 940.
And the reason for that is we do not send START_ENCRYPTION_EVENT to the slave
Solution:-
Send Start_encryption_log_event as Ignorable_log_event to slave(mysqlbinlog),
So that mysqlbinlog can update its log_pos.
Since Slave can request multiple FORMAT_DESCRIPTION_EVENT while master does not
have so We only update slave master pos when master actually have the
FORMAT_DESCRIPTION_EVENT. Similar logic should be applied for START_ENCRYPTION_EVENT.
Also added the test case when new server reads the data from old server which
does not send START_ENCRYPTION_EVENT to slave.
Master Slave Upgrade Scenario.
When Slave is updated first, Slave will have extra logic of handling
START_ENCRYPTION_EVENT But master willnot be sending START_ENCRYPTION_EVENT.
So there will be no issue.
When Master is updated first, It will send START_ENCRYPTION_EVENT to
slave , But slave will ignore this event in queue_event.
Fix rpl_skip_error test.
We cant reset Slave_skipped_errors(even with FLUSH STATUS), So instead
of absolute slave_skipped_errors we look for delta of slave_skipped_errors
Fix rpl.rpl_binlog_errors and binlog_encryption.rpl_binlog_errors
We create the $load_file and $load_file2 but we never remove them.
Fix rpl_000011.test
Instead of real value use delta value , Since flush status wont flush
LONGLONG variable.
Fix rpl_row_find_row_debug
Instead of searching whole log_error_ file we will use search_pattern_in_file
which runs pattern search only on latest test run , instead of full file.
Fix rpl_ip_mix rpl_ip_mix2
We should call reset slave all because we also want to reset master_host
otherwise show slave status wont be empty and making repeat N a failure.
Fix rpl_rotate_logs
First we have to remove master.info file (cleanup) and second we have to
call reset slave all because if we do not call reset slave all then we wont
read master.info file beacuse we already have master config in memory.
And this makes start slave to pass , which shoud fail becuase its permision
is 000
Fix circular_serverid0 test
The reason is that ++dbug_rows_event_count == 2 in queue_event does
not take --repeat into account. So I have reseted the dbug_rows_event_count
in if body.
calc_field_event_length should accurately calculate the size of BLOB type
fields, Instead of returning just the bytes taken by length it should return
length bytes + actual length.
read_statistics_for_tables_if_needed
Regression after 279a907, read_statistics_for_tables_if_needed() was
called after open_normal_and_derived_tables() failure.
Fixed by moving read_statistics_for_tables() call to a branch of
get_schema_stat_record() where result of open_normal_and_derived_tables()
is checked.
Removed THD::force_read_stats, added read_statistics_for_tables() instead.
Simplified away statistics_for_command_is_needed().
LEX::parsed_select_expr_cont(): Replace a condition with an
assertion DBUG_ASSERT(!s2->next_select()), and always
initialize sel1=s2, because all subsequent code paths will
assign to sel1->first_nested.
This was flagged by GCC reporting -Wmaybe-uninitialized
for the statement last->link_neighbour(sel1).
This applies to large allocations.
This maps to the way Linux does it in MDEV-10814 except FreeBSD uses
different constants.
Adjust error string to match to implementation.
Tested on FreeBSD-12.0
When "--export" mariabackup option is used, mariabackup starts the server in
bootstrap mode to generate *.cfg files for the certain innodb tables.
The started instance of the server reads options from the file, pointed
out in "--defaults-file" mariabackup option.
If the server uses the same config file as mariabackup, and binlog is
switched on in that config file, then "mariabackup --prepare --export"
will create binary log files in the server's binary log directory, what
can cause issues.
The fix is to add "--skip-log-bin" in mysld options when the server is
started to generate *.cfg files.
* MDEV-20225 BF aborting SP execution
When stored procedure execution was chosen as victim for a BF abort, the old implemnetationn called for rollback immediately
when execution was inside SP isntruction. Technically this happened in wsrep_after_statement() call, which identified the
need for a rollback.
The problem was that MariaDB does not accept rollback (nor commit) inside sub statement, there are several asserts about it,
checking for THD::in_sub_stmt.
This patch contains a fix, which skips calling wsrep_after_statement() for SP execution, which is marked as BF must abort. Instead,
we return error code to upper level, where rollback will eventually happen, ouside of SP execution.
Also, appending the affected trigger table (dropped or created) in the populated key set for the write set,
which prevents parallel applying of other transactions working on the same table.
* MDEV-20225 BF aborting SP execution, second patch
First PR missed 4 commits, which are now squashed in this patch:
- Added galera_sp_bf_abort test.
A MTR test case which will reproduce BF-BF conflict if all keys
corresponding to affected tables are not assigned for DROP TRIGGER.
- Fixed incorrect use of sync pointsin MDEV-20225
- Added condition for SQLCOM_DROP_TRIGGER in wsrep_can_run_in_toi()
to make it replicate.
* MDEV-20225 BF aborting SP execution, third patch
The galera_trigger.test caused a situation, where SP invocation caused a trigger
to fire, and the trigger executed as sub statement SP, and was BF aborted by applier.
because of wsrep_after_statement() was called for the sub-statement level, it ended up
in exeuting rollback and asserted there.
Thus fix will catch sub-statement level SP execution, and avoids calling wsrep_after_statement()
