685d958e38 MDEV-14425 Improve the redo log for concurrency 
The InnoDB redo log used to be formatted in blocks of 512 bytes.
The log blocks were encrypted and the checksum was calculated while
holding log_sys.mutex, creating a serious scalability bottleneck.

We remove the fixed-size redo log block structure altogether and
essentially turn every mini-transaction into a log block of its own.
This allows encryption and checksum calculations to be performed
on local mtr_t::m_log buffers, before acquiring log_sys.mutex.
The mutex only protects a memcpy() of the data to the shared
log_sys.buf, as well as the padding of the log, in case the
to-be-written part of the log would not end in a block boundary of
the underlying storage. For now, the "padding" consists of writing
a single NUL byte, to allow recovery and mariadb-backup to detect
the end of the circular log faster.

Like the previous implementation, we will overwrite the last log block
over and over again, until it has been completely filled. It would be
possible to write only up to the last completed block (if no more
recent write was requested), or to write dummy FILE_CHECKPOINT records
to fill the incomplete block, by invoking the currently disabled
function log_pad(). This would require adjustments to some logic around
log checkpoints, page flushing, and shutdown.

An upgrade after a crash of any previous version is not supported.
Logically empty log files from a previous version will be upgraded.

An attempt to start up InnoDB without a valid ib_logfile0 will be
refused. Previously, the redo log used to be created automatically
if it was missing. Only with with innodb_force_recovery=6, it is
possible to start InnoDB in read-only mode even if the log file
does not exist. This allows the contents of a possibly corrupted
database to be dumped.

Because a prepared backup from an earlier version of mariadb-backup
will create a 0-sized log file, we will allow an upgrade from such
log files, provided that the FIL_PAGE_FILE_FLUSH_LSN in the system
tablespace looks valid.

The 512-byte log checkpoint blocks at 0x200 and 0x600 will be replaced
with 64-byte log checkpoint blocks at 0x1000 and 0x2000.

The start of log records will move from 0x800 to 0x3000. This allows us
to use 4096-byte aligned blocks for all I/O in a future revision.

We extend the MDEV-12353 redo log record format as follows.

(1) Empty mini-transactions or extra NUL bytes will not be allowed.
(2) The end-of-minitransaction marker (a NUL byte) will be replaced
with a 1-bit sequence number, which will be toggled each time when the
circular log file wraps back to the beginning.
(3) After the sequence bit, a CRC-32C checksum of all data
(excluding the sequence bit) will written.
(4) If the log is encrypted, 8 bytes will be written before
the checksum and included in it. This is part of the
initialization vector (IV) of encrypted log data.
(5) File names, page numbers, and checkpoint information will not be
encrypted. Only the payload bytes of page-level log will be encrypted.
The tablespace ID and page number will form part of the IV.
(6) For padding, arbitrary-length FILE_CHECKPOINT records may be written,
with all-zero payload, and with the normal end marker and checksum.
The minimum size is 7 bytes, or 7+8 with innodb_encrypt_log=ON.

In mariadb-backup and in Galera snapshot transfer (SST) scripts, we will
no longer remove ib_logfile0 or create an empty ib_logfile0. Server startup
will require a valid log file. When resizing the log, we will create
a logically empty ib_logfile101 at the current LSN and use an atomic rename
to replace ib_logfile0 with it. See the test innodb.log_file_size.

Because there is no mandatory padding in the log file, we are able
to create a dummy log file as of an arbitrary log sequence number.
See the test mariabackup.huge_lsn.

The parameter innodb_log_write_ahead_size and the
INFORMATION_SCHEMA.INNODB_METRICS counter log_padded will be removed.

The minimum value of innodb_log_buffer_size will be increased to 2MiB
(because log_sys.buf will replace recv_sys.buf) and the increment
adjusted to 4096 bytes (the maximum log block size).

The following INFORMATION_SCHEMA.INNODB_METRICS counters will be removed:

os_log_fsyncs
os_log_pending_fsyncs
log_pending_log_flushes
log_pending_checkpoint_writes

The following status variables will be removed:

Innodb_os_log_fsyncs (this is included in Innodb_data_fsyncs)
Innodb_os_log_pending_fsyncs (this was limited to at most 1 by design)

log_sys.get_block_size(): Return the physical block size of the log file.
This is only implemented on Linux and Microsoft Windows for now, and for
the power-of-2 block sizes between 64 and 4096 bytes (the minimum and
maximum size of a checkpoint block). If the block size is anything else,
the traditional 512-byte size will be used via normal file system
buffering.

If the file system buffers can be bypassed, a message like the following
will be issued:

InnoDB: File system buffers for log disabled (block size=512 bytes)
InnoDB: File system buffers for log disabled (block size=4096 bytes)

This has been tested on Linux and Microsoft Windows with both sizes.

On Linux, only enable O_DIRECT on the log for innodb_flush_method=O_DSYNC.
Tests in 3 different environments where the log is stored in a device
with a physical block size of 512 bytes are yielding better throughput
without O_DIRECT. This could be due to the fact that in the event the
last log block is being overwritten (if multiple transactions would
become durable at the same time, and each of will write a small
number of bytes to the last log block), it should be faster to re-copy
data from log_sys.buf or log_sys.flush_buf to the kernel buffer,
to be finally written at fdatasync() time.

The parameter innodb_flush_method=O_DSYNC will imply O_DIRECT for
data files. This option will enable O_DIRECT on the log file on Linux.
It may be unsafe to use when the storage device does not support
FUA (Force Unit Access) mode.

When the server is compiled WITH_PMEM=ON, we will use memory-mapped
I/O for the log file if the log resides on a "mount -o dax" device.
We will identify PMEM in a start-up message:

InnoDB: log sequence number 0 (memory-mapped); transaction id 3

On Linux, we will also invoke mmap() on any ib_logfile0 that resides
in /dev/shm, effectively treating the log file as persistent memory.
This should speed up "./mtr --mem" and increase the test coverage of
PMEM on non-PMEM hardware. It also allows users to estimate how much
the performance would be improved by installing persistent memory.
On other tmpfs file systems such as /run, we will not use mmap().

mariadb-backup: Eliminated several variables. We will refer
directly to recv_sys and log_sys.

backup_wait_for_lsn(): Detect non-progress of
xtrabackup_copy_logfile(). In this new log format with
arbitrary-sized blocks, we can only detect log file overrun
indirectly, by observing that the scanned log sequence number
is not advancing.

xtrabackup_copy_logfile(): On PMEM, do not modify the sequence bit,
because we are not allowed to modify the server's log file, and our
memory mapping is read-only.

trx_flush_log_if_needed_low(): Do not use the callback on pmem.
Using neither flush_lock nor write_lock around PMEM writes seems
to yield the best performance. The pmem_persist() calls may
still be somewhat slower than the pwrite() and fdatasync() based
interface (PMEM mounted without -o dax).

recv_sys_t::buf: Remove. We will use log_sys.buf for parsing.

recv_sys_t::MTR_SIZE_MAX: Replaces RECV_SCAN_SIZE.

recv_sys_t::file_checkpoint: Renamed from mlog_checkpoint_lsn.

recv_sys_t, log_sys_t: Removed many data members.

recv_sys.lsn: Renamed from recv_sys.recovered_lsn.
recv_sys.offset: Renamed from recv_sys.recovered_offset.
log_sys.buf_size: Replaces srv_log_buffer_size.

recv_buf: A smart pointer that wraps log_sys.buf[recv_sys.offset]
when the buffer is being allocated from the memory heap.

recv_ring: A smart pointer that wraps a circular log_sys.buf[] that is
backed by ib_logfile0. The pointer will wrap from recv_sys.len
(log_sys.file_size) to log_sys.START_OFFSET. For the record that
wraps around, we may copy file name or record payload data to
the auxiliary buffer decrypt_buf in order to have a contiguous
block of memory. The maximum size of a record is less than
innodb_page_size bytes.

recv_sys_t::parse(): Take the smart pointer as a template parameter.
Do not temporarily add a trailing NUL byte to FILE_ records, because
we are not supposed to modify the memory-mapped log file. (It is
attached in read-write mode already during recovery.)

recv_sys_t::parse_mtr(): Wrapper for recv_sys_t::parse().

recv_sys_t::parse_pmem(): Like parse_mtr(), but if PREMATURE_EOF would be
returned on PMEM, use recv_ring to wrap around the buffer to the start.

mtr_t::finish_write(), log_close(): Do not enforce log_sys.max_buf_free
on PMEM, because it has no meaning on the mmap-based log.

log_sys.write_to_buf: Count writes to log_sys.buf. Replaces
srv_stats.log_write_requests and export_vars.innodb_log_write_requests.
Protected by log_sys.mutex. Updated consistently in log_close().
Previously, mtr_t::commit() conditionally updated the count,
which was inconsistent.

log_sys.write_to_log: Count swaps of log_sys.buf and log_sys.flush_buf,
for writing to log_sys.log (the ib_logfile0). Replaces
srv_stats.log_writes and export_vars.innodb_log_writes.
Protected by log_sys.mutex.

log_sys.waits: Count waits in append_prepare(). Replaces
srv_stats.log_waits and export_vars.innodb_log_waits.

recv_recover_page(): Do not unnecessarily acquire
log_sys.flush_order_mutex. We are inserting the blocks in arbitary
order anyway, to be adjusted in recv_sys.apply(true).

We will change the definition of flush_lock and write_lock to
avoid potential false sharing. Depending on sizeof(log_sys) and
CPU_LEVEL1_DCACHE_LINESIZE, the flush_lock and write_lock could
share a cache line with each other or with the last data members
of log_sys.

Thanks to Matthias Leich for providing https://rr-project.org traces
for various failures during the development, and to
Thirunarayanan Balathandayuthapani for his help in debugging
some of the recovery code. And thanks to the developers of the
rr debugger for a tool without which extensive changes to InnoDB
would be very challenging to get right.

Thanks to Vladislav Vaintroub for useful feedback and
to him, Axel Schwenke and Krunal Bauskar for testing the performance.

36e81a23c5 MDEV-11937: InnoDB flushes redo log too often 
Problem was introduced with the InnoDB 5.7 merge, the code related to
avoiding extra fsync at the end of commit when binlog is enabled. The
MariaDB method for this was removed, but the replacement MySQL method
based on thd_get_durability_property() is not functional in MariaDB.

This commit reverts the offending parts of the merge and adds a test
case, to fix the problem for InnoDB. But other storage engines are
likely to have a similar problem.

7e80f1c5dc Bug #49741 test files contain explicit references to bin/relay-log positions 
Some of the test cases reference to binlog position and
these position numbers are written into result explicitly.
It is difficult to maintain if log event format changes. 

There are a couple of cases explicit position number appears, 
we handle them in different ways
A. 'CHANGE MASTER ...' with MASTER_LOG_POS or/and RELAY_LOG_POS options
   Use --replace_result to mask them.
B. 'SHOW BINLOG EVENT ...'
   Replaced by show_binlog_events.inc or wait_for_binlog_event.inc. 
   show_binlog_events.inc file's function is enhanced by given
   $binlog_file and $binlog_limit.
C. 'SHOW SLAVE STATUS', 'show_slave_status.inc' and 'show_slave_status2.inc'
   For the test cases just care a few items in the result of 'SHOW SLAVE STATUS',
   only the items related to each test case are showed.
   'show_slave_status.inc' is rebuild, only the given items in $status_items
   will be showed.
   'check_slave_is_running.inc' and 'check_slave_no_error.inc'
   and 'check_slave_param.inc' are auxiliary files helping
   to show running status and error information easily.

946fad3502 Draft patch that fixes and a sketches test cases for: 
Bug#20837 Apparent change of isolation level during transaction,
Bug#46527 COMMIT AND CHAIN RELEASE does not make sense,
Bug#53343 completion_type=1, COMMIT/ROLLBACK AND CHAIN don't 
preserve the isolation level
Bug#53346 completion_type has strange effect in a stored 
procedure/prepared statement

Make thd->tx_isolation mean strictly "current transaction 
isolation level"
Make thd->variables.tx_isolation mean "current session isolation
level".
The current transaction isolation level is now established
at transaction start. If there was a SET TRANSACTION
ISOLATION LEVEL statement, the value is taken from it.
Otherwise, the session value is used.
A change in a session value, made while a transaction is active,
whereas still allowed, no longer has any effect on the
current transaction isolation level. This is an incompatible
change.
A change in a session isolation level, made while there is
no active transaction, overrides SET TRANSACTION statement,
if there was any.
Changed the impelmentation to not look at @@session.completion_type
in the parser, and thus fixed Bug#53346.
Changed the parser to not allow AND NO CHAIN RELEASE,
and thus fixed Bug#46527.
Changed the transaction API to take the current transaction
isolation level into account:
- BEGIN/COMMIT now do preserve the current transaction
isolation level if chaining is on.
- implicit commit, XA COMMIT or XA ROLLBACK or autocommit don't.

41783de549 BUG#39934: Slave stops for engine that only support row-based logging 
General overview:
The logic for switching to row format when binlog_format=MIXED had
numerous flaws. The underlying problem was the lack of a consistent
architecture.
General purpose of this changeset:
This changeset introduces an architecture for switching to row format
when binlog_format=MIXED. It enforces the architecture where it has
to. It leaves some bugs to be fixed later. It adds extensive tests to
verify that unsafe statements work as expected and that appropriate
errors are produced by problems with the selection of binlog format.
It was not practical to split this into smaller pieces of work.

Problem 1:
To determine the logging mode, the code has to take several parameters
into account (namely: (1) the value of binlog_format; (2) the
capabilities of the engines; (3) the type of the current statement:
normal, unsafe, or row injection). These parameters may conflict in
several ways, namely:
 - binlog_format=STATEMENT for a row injection
 - binlog_format=STATEMENT for an unsafe statement
 - binlog_format=STATEMENT for an engine only supporting row logging
 - binlog_format=ROW for an engine only supporting statement logging
 - statement is unsafe and engine does not support row logging
 - row injection in a table that does not support statement logging
 - statement modifies one table that does not support row logging and
   one that does not support statement logging
Several of these conflicts were not detected, or were detected with
an inappropriate error message. The problem of BUG#39934 was that no
appropriate error message was written for the case when an engine
only supporting row logging executed a row injection with
binlog_format=ROW. However, all above cases must be handled.
Fix 1:
Introduce new error codes (sql/share/errmsg.txt). Ensure that all
conditions are detected and handled in decide_logging_format()

Problem 2:
The binlog format shall be determined once per statement, in
decide_logging_format(). It shall not be changed before or after that.
Before decide_logging_format() is called, all information necessary to
determine the logging format must be available. This principle ensures
that all unsafe statements are handled in a consistent way.
However, this principle is not followed:
thd->set_current_stmt_binlog_row_based_if_mixed() is called in several
places, including from code executing UPDATE..LIMIT,
INSERT..SELECT..LIMIT, DELETE..LIMIT, INSERT DELAYED, and
SET @@binlog_format. After Problem 1 was fixed, that caused
inconsistencies where these unsafe statements would not print the
appropriate warnings or errors for some of the conflicts.
Fix 2:
Remove calls to THD::set_current_stmt_binlog_row_based_if_mixed() from
code executed after decide_logging_format(). Compensate by calling the
set_current_stmt_unsafe() at parse time. This way, all unsafe statements
are detected by decide_logging_format().

Problem 3:
INSERT DELAYED is not unsafe: it is logged in statement format even if
binlog_format=MIXED, and no warning is printed even if
binlog_format=STATEMENT. This is BUG#45825.
Fix 3:
Made INSERT DELAYED set itself to unsafe at parse time. This allows
decide_logging_format() to detect that a warning should be printed or
the binlog_format changed.

Problem 4:
LIMIT clause were not marked as unsafe when executed inside stored
functions/triggers/views/prepared statements. This is
BUG#45785.
Fix 4:
Make statements containing the LIMIT clause marked as unsafe at
parse time, instead of at execution time. This allows propagating
unsafe-ness to the view.


mysql-test/extra/rpl_tests/create_recursive_construct.inc:
  Added auxiliary file used by binlog_unsafe.test to create and
  execute recursive constructs
  (functions/procedures/triggers/views/prepared statements).
mysql-test/extra/rpl_tests/rpl_foreign_key.test:
  removed unnecessary set @@session.binlog_format
mysql-test/extra/rpl_tests/rpl_insert_delayed.test:
  Filter out table id from table map events in binlog listing.
  Got rid of $binlog_format_statement.
mysql-test/extra/rpl_tests/rpl_ndb_apply_status.test:
  disable warnings around call to unsafe procedure
mysql-test/include/rpl_udf.inc:
  Disabled warnings for code that generates warnings
  for some binlog formats. That would otherwise cause
  inconsistencies in the result file.
mysql-test/r/mysqldump.result:
  Views are now unsafe if they contain a LIMIT clause.
  That fixed BUG#45831. Due to BUG#45832, a warning is
  printed for the CREATE VIEW statement.
mysql-test/r/sp_trans.result:
  Unsafe statements in stored procedures did not give a warning if
  binlog_format=statement. This is BUG#45824. Now they do, so this
  result file gets a new warning.
mysql-test/suite/binlog/r/binlog_multi_engine.result:
  Error message changed.
mysql-test/suite/binlog/r/binlog_statement_insert_delayed.result:
  INSERT DELAYED didn't generate a warning when binlog_format=STATEMENT.
  That was BUG#45825. Now there is a warning, so result file needs to be
  updated.
mysql-test/suite/binlog/r/binlog_stm_ps.result:
  Changed error message.
mysql-test/suite/binlog/r/binlog_unsafe.result:
  updated result file:
   - error message changed
   - added test for most combinations of unsafe constructs invoked
     from recursive constructs
   - INSERT DELAYED now gives a warning (because BUG#45826 is fixed)
   - INSERT..SELECT..LIMIT now gives a warning from inside recursive
     constructs (because BUG#45785 was fixed)
   - When a recursive construct (e.g., stored proc or function)
     contains more than one statement, at least one of which is
     unsafe, then all statements in the recursive construct give
     warnings. This is a new bug introduced by this changeset.
     It will be addressed in a post-push fix.
mysql-test/suite/binlog/t/binlog_innodb.test:
  Changed error code for innodb updates with READ COMMITTED or 
  READ UNCOMMITTED transaction isolation level and
  binlog_format=statement.
mysql-test/suite/binlog/t/binlog_multi_engine.test:
  The error code has changed for statements where more than one
  engine is involved and one of them is self-logging.
mysql-test/suite/binlog/t/binlog_unsafe-master.opt:
  Since binlog_unsafe now tests unsafe-ness of UDF's, we need an extra
  flag in the .opt file.
mysql-test/suite/binlog/t/binlog_unsafe.test:
   - Clarified comment.
   - Rewrote first part of test. Now it tests not only unsafe variables
     and functions, but also unsafe-ness due to INSERT..SELECT..LIMIT,
     INSERT DELAYED, insert into two autoinc columns, use of UDF's, and
     access to log tables in the mysql database.
     Also, in addition to functions, procedures, triggers, and prepared
     statements, it now also tests views; and it constructs recursive
     calls in two levels by combining these recursive constructs.
     Part of the logic is in extra/rpl_tests/create_recursive_construct.inc.
   - added tests for all special system variables that should not be unsafe.
   - added specific tests for BUG#45785 and BUG#45825
mysql-test/suite/rpl/r/rpl_events.result:
  updated result file
mysql-test/suite/rpl/r/rpl_extraColmaster_innodb.result:

  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file equals
  the second half of the old rpl_found_rows.result, with the following
  modifications:
   - minor formatting changes
   - additional initialization
mysql-test/suite/rpl/r/rpl_mix_insert_delayed.result:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/r/rpl_rbr_to_sbr.result:
  updated result file
mysql-test/suite/rpl/r/rpl_row_idempotency.result:
  Moved the second half of rpl_idempotency.test, which only
  executed in row mode, to rpl_row_idempotency.test. This is
  the new result file.
mysql-test/suite/rpl/r/rpl_row_insert_delayed.result:
  Got rid of unnecessary explicit setting of binlog format.
mysql-test/suite/rpl/r/rpl_stm_found_rows.result:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
  this file:
   - minor formatting changes
   - warning is now issued for unsafe statements inside procedures
     (since BUG#45824 is fixed)
   - second half of file is moved to rpl_mix_found_rows.result
mysql-test/suite/rpl/r/rpl_stm_insert_delayed.result:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/r/rpl_stm_loadfile.result:
  error message changed
mysql-test/suite/rpl/r/rpl_temporary_errors.result:
  updated result file
mysql-test/suite/rpl/r/rpl_udf.result:
  Remove explicit set of binlog format (and triplicate test execution)
  and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl/t/rpl_bug31076.test:
  Test is only valid in mixed or row mode since it generates row events.
mysql-test/suite/rpl/t/rpl_events.test:
  Removed explicit set of binlog_format and removed duplicate testing.
  Instead, we rely on the test system to try all binlog formats.
mysql-test/suite/rpl/t/rpl_extraColmaster_innodb.test:
  Removed triplicate testing and instead relying on test system.
  Test is only relevant for row format since statement-based replication
  cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_extraColmaster_myisam.test:
  Removed triplicate testing and instead relying on test system.
  Test is only relevant for row format since statement-based replication
  cannot handle extra columns on master.
mysql-test/suite/rpl/t/rpl_idempotency-slave.opt:
  Removed .opt file to avoid server restarts.
mysql-test/suite/rpl/t/rpl_idempotency.test:
  - Moved out row-only tests to a new test file, rpl_row_idempotency.test.
    rpl_idempotency now only contains tests that execute in all
    binlog_formats.
  - While I was here, also removed .opt file to avoid server restarts.
    The slave_exec_mode is now set inside the test instead.
mysql-test/suite/rpl/t/rpl_mix_found_rows.test:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). This file
  contains the second half of the original rpl_found_rows.test with the
  follwing changes:
   - initialization
   - removed SET_BINLOG_FORMAT and added have_binlog_format_mixed.inc
   - minor formatting changes
mysql-test/suite/rpl/t/rpl_mix_insert_delayed.test:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/t/rpl_rbr_to_sbr.test:
  Test cannot execute in statement mode, since we no longer
  switch to row format when binlog_format=statement.
  Enforced mixed mode throughout the test.
mysql-test/suite/rpl/t/rpl_row_idempotency.test:
  Moved the second half of rpl_idempotency.test, which only
  executed in row mode, to this new file. We now rely on the
  test system to set binlog format.
mysql-test/suite/rpl/t/rpl_row_insert_delayed.test:
   - Got rid of unnecessary explicit setting of binlog format.
   - extra/rpl_tests/rpl_insert_delayed.test does not need the
     $binlog_format_statement variable any more, so that was
     removed.
mysql-test/suite/rpl/t/rpl_slave_skip.test:
  The test switches binlog_format internally and master generates both
  row and statement events. Hence, the slave must be able to log in both
  statement and row format. Hence test was changed to only execute in
  mixed mode.
mysql-test/suite/rpl/t/rpl_stm_found_rows.test:
  Split rpl_found_rows.test into rpl_mix_found_rows.test (a new file) and
  rpl_stm_found_rows.test (renamed rpl_found_rows.test). Changes in
  this file:
   - minor formatting changes
   - added have_binlog_format_statement and removed SET BINLOG_FORMAT.
   - second half of file is moved to rpl_mix_found_rows.test
   - added cleanup code
mysql-test/suite/rpl/t/rpl_stm_insert_delayed.test:
  Moved out code operating in mixed mode from rpl_stm_insert_delayed
  (into rpl_mix_insert_delayed) and got rid of explicit setting of
  binlog format.
mysql-test/suite/rpl/t/rpl_switch_stm_row_mixed.test:
  The test switches binlog_format internally and master generates both
  row and statement events. Hence, the slave must be able to log in both
  statement and row format. Hence test was changed to only execute in
  mixed mode on slave.
mysql-test/suite/rpl/t/rpl_temporary_errors.test:
  Removed explicit set of binlog format. Instead, the test now only
  executes in row mode.
mysql-test/suite/rpl/t/rpl_udf.test:
  Remove explicit set of binlog format (and triplicate test execution)
  and rely on test system executing the test in all binlog formats.
mysql-test/suite/rpl_ndb/combinations:
  Added combinations file for rpl_ndb.
mysql-test/suite/rpl_ndb/r/rpl_ndb_binlog_format_errors.result:
  new result file
mysql-test/suite/rpl_ndb/r/rpl_ndb_circular_simplex.result:
  updated result file
mysql-test/suite/rpl_ndb/t/rpl_ndb_2innodb.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.
mysql-test/suite/rpl_ndb/t/rpl_ndb_2myisam.test:
  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.

  The test needs slave to be able to switch to row mode, so the
  test was changed to only execute in mixed and row mode.

  The test needs slave to be able to switch to row mode, so the

mysql-test/t/partition_innodb_stmt.test:
  Changed error code for innodb updates with READ COMMITTED or 
  READ UNCOMMITTED transaction isolation level and
  binlog_format=statement.
sql/event_db_repository.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/events.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/ha_ndbcluster_binlog.cc:
  reset_current_stmt_binlog_row_based() is not a no-op for the ndb_binlog
  thread any more. Instead, the ndb_binlog thread now forces row mode both
  initially and just after calling mysql_parse.  (mysql_parse() is the only
  place where reset_current_stmt_binlog_row_based() may be called from
  the ndb_binlog thread, so these are the only two places that need to
  change.)
sql/ha_partition.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/handler.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/item_create.cc:
  Added DBUG_ENTER to some functions, to be able to trace when
  set_stmt_unsafe is called.
sql/log.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/log_event.cc:
   - Moved logic for changing to row format out of do_apply_event (and into
     decide_logging_format).
   - Added @todo comment for post-push cleanup.
sql/log_event_old.cc:
  Move logic for changing to row format out of do_apply_event (and into
  decide_logging_format).
sql/mysql_priv.h:
  Make decide_logging_format() a member of the THD class, for two reasons:
   - It is natural from an object-oriented perspective.
   - decide_logging_format() needs to access private members of THD
     (specifically, the new binlog_warning_flags field).
sql/rpl_injector.cc:
  Removed call to set_current_stmt_binlog_row_based().
  From now on, only decide_logging_fromat is allowed to modify
  current_stmt_binlog_row_based. This call is from the ndb_binlog
  thread, mostly executing code in ha_ndbcluster_binlog.cc.
  This call can be safely removed, because:
   - current_stmt_binlog_row_based is initialized for the ndb_binlog
     thread's THD object when the THD object is created. So we're
     not going to read uninitialized memory.
   - The behavior of ndb_binlog thread does not use the state of the
     current_stmt_binlog_row_based. It is conceivable that the
     ndb_binlog thread would rely on the current_stmt_binlog_format
     in two situations:
      (1) when it calls mysql_parse;
      (2) when it calls THD::binlog_query.
     In case (1), it always clears THD::options&OPTION_BIN_LOG (because
     run_query() in ha_ndbcluster_binlog.cc is only called with
     disable_binlogging = TRUE).
     In case (2), it always uses qtype=STMT_QUERY_TYPE.
sql/set_var.cc:
  Added @todo comment for post-push cleanup.
sql/share/errmsg.txt:
  Added new error messages and clarified ER_BINLOG_UNSAFE_STATEMENT.
sql/sp.cc:
  Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
  Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sp_head.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sp_head.h:
  Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_acl.cc:
  Got rid of MYSQL_QUERY_TYPE: it was equivalent to STMT_QUERY_TYPE.
sql/sql_base.cc:
   - Made decide_logging_format take care of all logic for deciding the
     logging format, and for determining the related warnings and errors.
     See comment above decide_logging_format for details.
   - Made decide_logging_format a member function of THD, since it needs
     to access private members of THD and since its purpose is to update
     the state of a THD object.
   - Added DBUG_ENTER, to be able to trace when set_stmt_unsafe is called.
sql/sql_class.cc:
  - Moved logic for determining unsafe warnings away from THD::binlog_query
    (and into decide_logging_format()). Now, it works like this:
    1. decide_logging_format detects that the current statement shall
       produce a warning, if it ever makes it to the binlog
    2. decide_logging_format sets a flag of THD::binlog_warning_flags.
    3. THD::binlog_query reads the flag. If the flag is set, it generates
       a warning.
  - Use member function to read current_stmt_binlog_row_based.
sql/sql_class.h:
  - Added THD::binlog_warning_flags (see sql_class.cc for explanation).
  - Made decide_logging_format() and reset_for_next_command() member
    functions of THD (instead of standalone functions). This was needed
    for two reasons: (1) the functions need to access the private member
    THD::binlog_warning_flags; (2) the purpose of these functions is to
    update the staet of a THD object, so from an object-oriented point
    of view they should be member functions.
  - Encapsulated current_stmt_binlog_row_based, so it is now private and
    can only be accessed from a member function. Also changed the
    data type to an enumeration instead of a bool.
  - Removed MYSQL_QUERY_TYPE, because it was equivalent to
    STMT_QUERY_TYPE anyways.
  - When reset_current_stmt_binlog_row_based was called from the
    ndb_binlog thread, it would behave as a no-op. This special
    case has been removed, and the behavior of
    reset_current_stmt_binlog_row_based does not depend on which thread
    calls it any more. The special case did not serve any purpose,
    since the ndb binlog thread did not take the
    current_stmt_binlog_row_based flag into account anyways.
sql/sql_delete.cc:
  - Moved logic for setting row format for DELETE..LIMIT away from
    mysql_prepare_delete.
    (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
    and rely on decide_logging_format() (sql_class.cc) to set row format.)
    This is part of the fix for BUG#45831.
  - Use member function to read current_stmt_binlog_row_based.
sql/sql_insert.cc:
   - Removed unnecessary calls to thd->lex->set_stmt_unsafe() and
     thd->set_current_stmt_binlog_row_based_if_mixed() from
     handle_delayed_insert(). The calls are unnecessary because they
     have already been made; they were made in the constructor of
     the `di' object.
   - Since decide_logging_format() is now a member function of THD, code
     that calls decide_logging_format() had to be updated.
   - Added DBUG_ENTER call, to be able to trace when set_stmt_unsafe is
     called.
   - Moved call to set_stmt_unsafe() for INSERT..SELECT..LIMIT away from
     mysql_insert_select_prepare() (and into decide_logging_format).
     This is part of the fix for BUG#45831.
   - Use member function to read current_stmt_binlog_row_based.
sql/sql_lex.h:
   - Added the flag BINLOG_STMT_FLAG_ROW_INJECTION to enum_binlog_stmt_flag.
     This was necessary so that a statement can identify itself as a row
     injection.
   - Added appropriate setter and getter functions for the new flag.
   - Added or clarified some comments.
   - Added DBUG_ENTER()
sql/sql_load.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_parse.cc:
   - Made mysql_reset_thd_for_next_command() clear thd->binlog_warning_flags.
   - Since thd->binlog_warning_flags is private, it must be set in a
     member function of THD. Hence, moved the body of
     mysql_reset_thd_for_next_command() to the new member function
     THD::reset_thd_for_next_command(), and made
     mysql_reset_thd_for_next_command() call
     THD::reset_thd_for_next_command().
   - Removed confusing comment.
   - Use member function to read current_stmt_binlog_row_based.
sql/sql_repl.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_table.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_udf.cc:
  Use member function to read current_stmt_binlog_row_based.
sql/sql_update.cc:
  Moved logic for setting row format for UPDATE..LIMIT away from
  mysql_prepare_update.
  (Instead, we mark the statement as unsafe at parse time (sql_yacc.yy)
  and rely on decide_logging_format() (sql_class.cc) to set row format.)
  This is part of the fix for BUG#45831.
sql/sql_yacc.yy:
  Made INSERT DELAYED, INSERT..SELECT..LIMIT, UPDATE..LIMIT, and
  DELETE..LIMIT mark themselves as unsafe at parse time (instead
  of at execution time).
  This is part of the fixes BUG#45831 and BUG#45825.
storage/example/ha_example.cc:
  Made exampledb accept inserts. This was needed by the new test case
  rpl_ndb_binlog_format_errors, because it needs an engine that
  is statement-only (and accepts inserts).
storage/example/ha_example.h:
  Made exampledb a statement-only engine instead of a row-only engine.
  No existing test relied exampledb's row-only capabilities. The new
  test case rpl_ndb_binlog_format_errors needs an engine that is
  statement-only.
storage/innobase/handler/ha_innodb.cc:
  - Changed error error code and message given by innodb when 
    binlog_format=STATEMENT and transaction isolation level is
    READ COMMITTED or READ UNCOMMITTED.
  - While I was here, also simplified the condition for
    checking when to give the error.

88cd7a98a5 Fix a few problems after latest bunch of InnoDB snapshot changes: 
The binlog_innodb test was sensitive to what tests ran before it.  Now run
FLUSH STATUS before performing operations that need to be checked.

sys_var_thd_ulong::update() was improperly casting an option value from
ulonglong to ulong before comparing it to the max allowed value.  On systems
where ulong and ulonglong are of different size, this caused values greater
than ULONG_MAX to wrap around (not be truncated to ULONG_MAX, which appears to
have been the intention of the original coder), and caused some checks to work
incorrectly.  This wasn't generally visible to the user, because later checks
would prevent the wrapped-around value from being used.  But it caused warning
messages to differ between 32- and 64-bit platforms.  Fix is to just remove the
cast.  Also added a DBUG_ASSERT to ensure that the value really is capped
properly before finally stuffing it into the ulong.

sql/sql_table.cc:
  build_table_filename(): Don't add FN_ROOTDIR to mysql_data_home if
  it's already there.  This is done to make it easier to write tests
  which check the output of various error messages, and work with
  both the embedded server (mysql_data_home is full path, including
  trailing FN_ROOTDIR) and normal server (mysql_data_home is just ".").
