0bfa3dff8b MDEV-12698 innodb.innodb_stats_del_mark test failure
In my merge of the MySQL fix for Oracle Bug#23333990 / WL#9513
I overlooked some subsequent revisions to the test, and I also
failed to notice that the test is actually always failing.

Oracle introduced the parameter innodb_stats_include_delete_marked
but failed to consistently take it into account in FOREIGN KEY
constraints that involve CASCADE or SET NULL.

When innodb_stats_include_delete_marked=ON, obviously the purge of
delete-marked records should update the statistics as well.

One more omission was that statistics were never updated on ROLLBACK.
We are fixing that as well, properly taking into account the
parameter innodb_stats_include_delete_marked.

dict_stats_analyze_index_level(): Simplify an expression.
(Using the ternary operator with a constant operand is unnecessary
obfuscation.)

page_scan_method_t: Revert the change done by Oracle. Instead,
examine srv_stats_include_delete_marked directly where it is needed.

dict_stats_update_if_needed(): Renamed from
row_update_statistics_if_needed().

row_update_for_mysql_using_upd_graph(): Assert that the table statistics
are initialized, as guaranteed by ha_innobase::open(). Update the
statistics in a consistent way, both for FOREIGN KEY triggers and
for the main table. If FOREIGN KEY constraints exist, do not dereference
a freed pointer, but cache the proper value of node->is_delete so that
it matches prebuilt->table.

row_purge_record_func(): Update statistics if
innodb_stats_include_delete_marked=ON.

row_undo_ins(): Update statistics (on ROLLBACK of a fresh INSERT).
This is independent of the parameter; the record is not delete-marked.

row_undo_mod(): Update statistics on the ROLLBACK of updating key columns,
or (if innodb_stats_include_delete_marked=OFF) updating delete-marks.

innodb.innodb_stats_persistent: Renamed and extended from
innodb.innodb_stats_del_mark. Reduced the unnecessarily large dataset
from 262,144 to 32 rows. Test both values of the configuration
parameter innodb_stats_include_delete_marked.
Test that purge is updating the statistics.

innodb_fts.innodb_fts_multiple_index: Adjust the result. The test
is performing a ROLLBACK of an INSERT, which now affects the statistics.

include/wait_all_purged.inc: Moved from innodb.innodb_truncate_debug
to its own file.

021d636551 Fix some integer type mismatch.
Use uint32_t for the encryption key_id.

When filling unsigned integer values into INFORMATION_SCHEMA tables,
use the method Field::store(longlong, bool unsigned)
instead of using Field::store(double).

Fix also some miscellanous type mismatch related to ulint (size_t).

f9cc391863 Merge 10.1 into 10.2
This only merges MDEV-12253, adapting it to MDEV-12602 which is already
present in 10.2 but not yet in the 10.1 revision that is being merged.

TODO: Error handling in crash recovery needs to be improved.
If a page cannot be decrypted (or read), we should cleanly abort
the startup. If innodb_force_recovery is specified, we should
ignore the problematic page and apply redo log to other pages.
Currently, the test encryption.innodb-redo-badkey randomly fails
like this (the last messages are from cmake -DWITH_ASAN):

14fe6dd239 Bug #23046302 COUNT(*) MUCH SLOWER ON 5.7 THAN 5.6
ANALYSIS

This is regression caused due to worklog 6742 which
implemented ha_innobase::records() which always
uses clustered index to get the row count. Previously
optimizer chose secondary index which was smaller in
size of clustered index to scan for rows and resulted in
a quicker scan.

FIX

After discussion it was decided to remove this feature in 5.7.

97acc4a1c3 MDEV-12270 Port MySQL 8.0 Bug#21141390 REMOVE UNUSED FUNCTIONS AND CONVERT GLOBAL SYMBOLS TO STATIC
InnoDB defines some functions that are not called at all.
Other functions are called, but only from the same compilation unit.

Remove some function declarations and definitions, and add 'static'
keywords. Some symbols must be kept for separately compiled tools,
such as innochecksum.

4e1116b2c6 MDEV-12271 Port MySQL 8.0 Bug#23150562 REMOVE UNIV_MUST_NOT_INLINE AND UNIV_NONINL
Also, remove empty .ic files that were not removed by my MySQL commit.

Problem:
InnoDB used to support a compilation mode that allowed to choose
whether the function definitions in .ic files are to be inlined or not.
This stopped making sense when InnoDB moved to C++ in MySQL 5.6
(and ha_innodb.cc started to #include .ic files), and more so in
MySQL 5.7 when inline methods and functions were introduced
in .h files.

Solution:
Remove all references to UNIV_NONINL and UNIV_MUST_NOT_INLINE from
all files, assuming that the symbols are never defined.
Remove the files fut0fut.cc and ut0byte.cc which only mattered when
UNIV_NONINL was defined.

89d80c1b0b Fix many -Wconversion warnings.
Define my_thread_id as an unsigned type, to avoid mismatch with
ulonglong.  Change some parameters to this type.

Use size_t in a few more places.

Declare many flag constants as unsigned to avoid sign mismatch
when shifting bits or applying the unary ~ operator.

When applying the unary ~ operator to enum constants, explictly
cast the result to an unsigned type, because enum constants can
be treated as signed.

In InnoDB, change the source code line number parameters from
ulint to unsigned type. Also, make some InnoDB functions return
a narrower type (unsigned or uint32_t instead of ulint;
bool instead of ibool).

a45866c6db MDEV-12050 Remove unused InnoDB Memcached hooks
Oracle introduced a Memcached plugin interface to the InnoDB
storage engine in MySQL 5.6. That interface is essentially a
fork of Memcached development snapshot 1.6.0-beta1 of an old
development branch 'engine-pu'.

To my knowledge, there have not been any updates to the Memcached code
between MySQL 5.6 and 5.7; only bug fixes and extensions related to
the Oracle modifications.

The Memcached plugin is not part of the MariaDB Server. Therefore it
does not make sense to include the InnoDB interfaces for the Memcached
plugin, or to have any related configuration parameters:

    innodb_api_bk_commit_interval
    innodb_api_disable_rowlock
    innodb_api_enable_binlog
    innodb_api_enable_mdl
    innodb_api_trx_level

Removing this code in one commit makes it possible to easily restore
it, in case it turns out to be needed later.

7cf97ed4ee MDEV-11816 Disallow CREATE TEMPORARY TABLE…ROW_FORMAT=COMPRESSED
MySQL 5.7 allows temporary tables to be created in ROW_FORMAT=COMPRESSED.
The usefulness of this is questionable. WL#7899 in MySQL 8.0.0
prevents the creation of such compressed tables, so that all InnoDB
temporary tables will be located inside the predefined
InnoDB temporary tablespace.

Pick up and adjust some tests from MySQL 5.7 and 8.0.

dict_tf_to_fsp_flags(): Remove the parameter is_temp.
fsp_flags_init(): Remove the parameter is_temporary.

row_mysql_drop_temp_tables(): Remove. There cannot be any temporary
tables in InnoDB. (This never removed #sql* tables in the datadir
which were created by DDL.)

dict_table_t::dir_path_of_temp_table: Remove.

create_table_info_t::m_temp_path: Remove.

create_table_info_t::create_options_are_invalid(): Do not allow
ROW_FORMAT=COMPRESSED or KEY_BLOCK_SIZE for temporary tables.

create_table_info_t::innobase_table_flags(): Do not unnecessarily
prevent CREATE TEMPORARY TABLE with SPATIAL INDEX.
(MySQL 5.7 does allow this.)

fil_space_belongs_in_lru(): The only FIL_TYPE_TEMPORARY tablespace
is never subjected to closing least-recently-used files.

1eabad5dbe Remove MYSQL_COMPRESSION.
The MariaDB 10.1 page_compression is incompatible with the Oracle
implementation that was introduced in MySQL 5.7 later.

Remove the Oracle implementation. Also remove the remaining traces of
MYSQL_ENCRYPTION.

This will also remove traces of PUNCH_HOLE until it is implemented
better. The only effective call to os_file_punch_hole() was in
fil_node_create_low() to test if the operation is supported for the file.

In other words, it looks like page_compression is not working in
MariaDB 10.2, because no code equivalent to the 10.1 os_file_trim()
is enabled.

c868acdf65 MDEV-11487 Revert InnoDB internal temporary tables from WL#7682
WL#7682 in MySQL 5.7 introduced the possibility to create light-weight
temporary tables in InnoDB. These are called 'intrinsic temporary tables'
in InnoDB, and in MySQL 5.7, they can be created by the optimizer for
sorting or buffering data in query processing.

In MariaDB 10.2, the optimizer temporary tables cannot be created in
InnoDB, so we should remove the dead code and related data structures.

	The failure happened because 5.7 has changed the signature of

bfb6ea0232 MDEV-8589: Non-default ENCRYPTION_KEY_ID is ignored upon reading a table
Analysis: Problem was that when a new tablespace is created a default
encryption info is also created and stored to the tablespace. Later a
new encryption information was created with correct key_id but that
does not affect on IV.

Fix: Push encryption mode and key_id to lower levels and create
correct encryption info when a new tablespace is created.

This fix does not contain test case because, currently incorrect
encryption key causes page corruption and a lot of error messages
to error log causing mtr to fail.

cb37c55768 MDEV-6929: Port Facebook Prefix Index Queries Optimization
Merge Facebook commit 154c579b828a60722a7d9477fc61868c07453d08
and e8f0052f9b112dc786bf9b957ed5b16a5749f7fd authored
by Steaphan Greene from https://github.com/facebook/mysql-5.6

Optimize prefix index queries to skip cluster index lookup when possible.

Currently InnoDB will always fetch the clustered index (primary key
index) for all prefix columns in an index, even when the value of a
particular record is smaller than the prefix length. This change
optimizes that case to use the record from the secondary index and avoid
the extra lookup.

Also adds two status vars that track how effective this is:

innodb_secondary_index_triggered_cluster_reads:
Times secondary index lookup triggered cluster lookup.

innodb_secondary_index_triggered_cluster_reads_avoided:
Times prefix optimization avoided triggering cluster lookup.

branches/5.1: Fix a bug in multi-table semi-consistent reads.
Remember the acquired record locks per table handle (row_prebuilt_t)
rather than per transaction (trx_t), so that unlock_row should successfully
unlock all non-matching rows in multi-table operations.
This deficiency was found while investigating Bug #39320.

A follow-up fix for Bug 38839, which exposed a pre-existing bug in the
autoinc handling.

Detailed revision comments:

r2722 | sunny | 2008-10-04 02:48:04 +0300 (Sat, 04 Oct 2008) | 18 lines
branches/5.1: This bug has always existed but was masked by other errors. The
fix for bug# 38839 triggered this bug. When the offset and increment are > 1
we need to calculate the next value taking into consideration the two
variables. Previously we simply assumed they were 1 particularly offset was
never used. MySQL does its own calculation and that's probably why it seemed
to work in the past. We would return what we thought was the correct next
value and then MySQL would recalculate the actual value from that and return
it to the caller (e.g., handler::write_row()). Several new tests have been
added that try and catch some edge cases. The tests exposed a wrap around
error in MySQL next value calculation which was filed as bug 39828. The tests
will need to be updated once MySQL fix that bug.

One good side effect of this fix is that dict_table_t size has been
reduced by 8 bytes because we have moved the autoinc_increment field to
the row_prebuilt_t structure. See review-board for a detailed discussion.

branches/5.1: Fix for Bug# 35352. We've added a heuristic that checks
the size of the UNDO slots cache lists (insert and upate). If either of
cached lists has more than 500 entries then we add any UNDO slots that are
freed, to the common free list instead of the cache list, this is to avoid
the case where all the free slots end up in only one of the lists on startup
after a crash.

Tested with test case for 26590 and passes all mysql-test(s).

  Fixed bug#30059.
  Server handles truncation for assignment of too-long values
  into CHAR/VARCHAR/TEXT columns in a different ways when the
  truncated characters are spaces:
  1. CHAR(N) columns silently ignore end-space truncation;
  2. TEXT columns post a truncation warning/error in the
     non-strict/strict mode.
  3. VARCHAR columns always post a truncation note in
     any mode.

  Space truncation processing has been synchronised over
  CHAR/VARCHAR/TEXT columns: current behavior of VARCHAR
  columns has been propagated as standard.

  Binary-encoded string/BLOB columns are not affected.

- Bug #33349: possible race condition revolving around data dictionary and repartitioning
  Introduce retry/sleep logic as a workaround for a transient bug
  where ::open fails for partitioned tables randomly if we are using
  one file per table.

- Bug #34053: normal users can enable innodb_monitor logging
  In CREATE TABLE and DROP TABLE check whether the table in question is one

  to mess with it before doing anything else.

- Bug #22868: 'Thread thrashing' with > 50 concurrent conns under an upd-intensive workloadw
- Bug #29560: InnoDB >= 5.0.30 hangs on adaptive hash rw-lock 'waiting for an X-lock'
  This is a combination of changes that forward port the scalability fix applied to 5.0
  through r1001.
  It reverts changes r149 and r122 (these were 5.1 specific changes made in lieu of
  scalability fix of 5.0)
  Then it applies r1001 to 5.0 which is the original scalability fix.
  Finally it applies r2082 which fixes an issue with the original fix.

  Looks like these strings are "automatically" wrapped by MySQL in the
  following way:
  * newlines (\n) in the string are ignored
  * newline separator (\n) is inserted every 57 or so characters.
  * lots of white space is appended to each inserted new line.

Fixes the following bugs:

Bug #30706: SQL thread on slave is allowed to block client queries when slave load is high
  Add (innodb|innobase|srv)_replication_delay MySQL config parameter.

Bug #30888: Innodb table + stored procedure + row deletion = server crash
  While adding code for the low level read of the AUTOINC value from the index,
  the case for MEDIUM ints which are 3 bytes was missed triggering an
  assertion.

Bug #30907: Regression: "--innodb_autoinc_lock_mode=0" (off) not same as older releases
  We don't rely on *first_value to be 0 when checking whether
  get_auto_increment() has been invoked for the first time in a multi-row
  INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows
  inside ha_innobase::start_stmt() too.

Bug #31444: "InnoDB: Error: MySQL is freeing a thd" in innodb_mysql.test
  ha_innobase::external_lock(): Update prebuilt->mysql_has_locked and
  trx->n_mysql_tables_in_use only after row_lock_table_for_mysql() returns
  DB_SUCCESS.  A timeout on LOCK TABLES would lead to an inconsistent state,
  which would cause trx_free() to print a warning.

Bug #31494: innodb + 5.1 + read committed crash, assertion
  Set an error code when a deadlock occurs in semi-consistent read.

  Fixed bug#28404.
  This patch adds cost estimation for the queries with ORDER BY / GROUP BY
  and LIMIT.
  If there was a ref/range access to the table whose rows were required
  to be ordered in the result set the optimizer always employed this access
  though a scan by a different index that was compatible with the required
  order could be cheaper to produce the first L rows of the result set.
  Now for such queries the optimizer makes a choice between the cheapest
  ref/range accesses not compatible with the given order and index scans
  compatible with it.

  Revision r1862:
  Add ut_snprintf() function. On Windows this needs to be implemented

  Windows that behaves exactly as specified in the standard:
  
  * Always return the number of characters that would have been printed
    if the size were unlimited (not including the final `\0').
  * Always '\0'-terminate the result
  * Do not touch the buffer if size=0, only return the number of characters
    that would have been printed. Can be used to estimate the size needed
    and to allocate it dynamically.

  Revision r1820:
  Use the clustered index and not the one selected by the optimizer in the plan,
  when building a previous version of the row. This bug is triggered when
  running queries via InnoDB's internal SQL parser; when InnoDB's optimizer
  selects a secondary index for the plan.
  
  
  Revision r1828:
  Fix two bugs:
  
  Bug# 30907: We don't rely on *first_value to be 0 when checking whether
  get_auto_increment() has been invoked for the first time in a multi-row
  INSERT. We instead use trx_t::n_autoinc_rows. Initialize trx::n_autoinc_rows
  inside ha_innobase::start_stmt() too.
  
  Bug# 30888: While adding code for the low level read of the AUTOINC value
  from the index, the case for MEDIUM ints which are 3 bytes was missed
  triggering an assertion.

  Revision r1873:
  snprintf() should always return non-negative result. According to
  Microsoft documentation about _vscprintf():
  
    If format is a null pointer, the invalid parameter handler is invoked,
    as described in Parameter Validation. If execution is allowed to
    continue, the functions return -1 and set errno to EINVAL.
  
  The UNIX variant of snprintf() segfaults if format is a NULL pointer
  (similar to strlen(NULL) for example), so it is better to conform to
  this behavior and crash our custom Windows version instead of
  returning -1. Noone would expect -1 to be returned from snprintf().
  
  Cosmetic: Add a space after typecast.
  
  Approved by:	Marko

  Summary of structural changes:
  ==============================
  InnoDB needs to hold a table level lock for AUTOINC allocations to overcome
  the non-determinism inherent in MySQL SBR for INSERT ... SELECT. In this fix 
  for simple INSERT statements (including multi-value inserts), we try and avoid
  acquiring the special AUTOINC table level lock unless another transaction has
  already reserved the AUTOINC table level lock, in which case we fall back
  to the old behavior of acquiring the AUTOINC table level lock.
  
  The max AUTOINC value is now read directly using the low level interface
  of InnoDB.
  
  
  Revision r1719:
  Merge r1264 from branches/zip: Avoid memory fragmentation when
  adding column definitions to tables.
  
  dict_mem_table_add_col(): Add the parameter "heap" for temporary memory
  allocation.  Allow it and "name" to be NULL.  These parameters are NULL
  when creating dummy indexes.
  
  dict_add_col_name(): Remove calls to ut_malloc() and ut_free().
  
  dict_table_get_col_name(): Allow table->col_names to be NULL.
  
  dict_table_add_system_columns(), dict_table_add_to_cache():
  Add the parameter "heap".

  is one test that fails as of this commit. The updated test case should be
  part of the snapshot from MySQL shortly.
  
  Fix for bug# 27950 - Init AUTOINC from delete_row().
  
  Fix for bug# 28781 - Use value specified by MySQL, in update_row().
  
  Summary of structural changes:
  ==============================
  InnoDB needs to hold a table level lock for AUTOINC allocations to overcome
  the non-determinism inherent in MySQL SBR for INSERT ... SELECT. In this fix 
  for simple INSERT statements (including multi-value inserts), we try and avoid
  acquiring the special AUTOINC table level lock unless another transaction has
  already reserved the AUTOINC table level lock, in which case we fall back
  to the old behavior of acquiring the AUTOINC table level lock.
  
  The max AUTOINC value is now read directly using the low level interface
  of InnoDB.
storage/innobase/include/row0sel.h:
  Apply InnoDB snapshot innodb-5.1-ss1726.

  Revision r1632:
  Add include/lock0priv.h to noinst_HEADERS in Makefile.am.
  
  
  
  Revision r1636:
  Move lock_get_type() from lock/lock0lock.c to include/lock0priv.ic:
  * lock0lock.c: remove lock_get_type() and include include/lock0priv.ic
  * lock0priv.h: include lock0priv.ic and add lock_get_type() prototype
  * Makefile.am: add lock0priv.ic to noinst_HEADERS
  * lock0priv.ic: introduce this new file containing the body of
    lock_get_type()
  
  This move is necessary in order to use lock_get_type() from other lock/
  source files (it's going to be used in lock/lock0iter.c).

  Revision r1638:
  Introduce a lock queue iterator for easy (and opaque) traversing of lock
  queues. Supports table and record lock queues via the same interface.
  
  There is only "get previous" method because currently there is no need
  for "get next" - it would be unused. Feel free to add one if needed.

  Fix Bug#29097 "fsp_get_available_space_in_free_extents() is capped at 4TB"
  by typecasting the variables before multiplying them, so that the result of
  the multiplication is of type "unsigned long long".
  
  I verified this fix by creating a sparse file of 6TB and forcing InnoDB to
  use it without overwriting it with zeroes (by commenting the code that
  overwrites :newraw files).
  
  New type ullint is introduced with the sole purpose of shortening
  "unsigned long long", please do not define it to something else than
  "unsigned long long".

32b5fb7323 Apply the following innodb-5.1-* snapshots: ss1489, ss1496, ss1550, ss1569.
After applying the snapshots, ensure that code conforms to the final version
of WL 3914.

It is signficant that, after these changes, InnoDB does not define MYSQL_SERVER,
and can be built as an independent storage engine plugin.

  Add the number of locks acquired by a transaction to its weight when
  choosing the lightest transaction to kill when a deadlock occurs.
  This fixes Bug#21293 partially.
  
  Approved by:	Heikki
  
  
  
  Revision r1501:
  Fix Bug#21293: Consider transactions that had edited non-transactional
  tables heavier than ones that had not. This helps killing the "right"
  transaction in case of a deadlock.
  
  Approved by:	Heikki
  
  
  Revision r1522:
  trx0trx.c: Add missing #include "ha_prototypes.h".
storage/innobase/trx/trx0undo.c:
  Apply the following innodb-5.1-* snapshots:  ss1489, ss1496, ss1550, ss1569.
  
  Revision r1423:
  Fix for Bug#18828. Return DB_TOO_MANY_CONCURRENT_TRXS when we run out
  of UNDO slots in the rollback segment. This is a partial fix since the
  MySQL error code requested to properly report the error condition back
  to the client has not yet materialized. Currently we have #ifdef'd the
  error code translation in ha_innodb.cc. This will have to be changed
  as and when MySQl add the new requested code or an equivalent code
  that we can then use.
  
  Given the above, currently we will get the old behaviour, not the "fixed"
  and intended behaviour.
storage/innobase/ut/ut0ut.c:
  Apply the following innodb-5.1-* snapshots:  ss1489, ss1496, ss1550, ss1569.
  
  Revision r1490:
  Add #include <ctype.h>.  Apparently, this header is no longer included by
  the common headers.  This may be related to WL#2936
  (pluggable storage engines).
mysql-test/r/innodb_trx_weight.result:
  Apply the following innodb-5.1-* snapshots:  ss1489, ss1496, ss1550, ss1569.
  
  Revision r1498:
  Add a test about the behavior introduced in r1497.

  Revision r1556:
  mysql-test/innodb_trx_weight.inc: Add username root to the "connect" statement.
  The Unix user running mysql-test-run usually does not have any privileges
  on the MySQL test database.
mysql-test/t/innodb_trx_weight.test:
  Fixes after merging InnoDB snapshots.

  Revision r1488:
  Make InnoDB pluggable.  That is, merge the modifications from MySQL WL#2936
  and adapt some things.
  
  Note that ha_innodb.cc depends on mysql_tmpfile() being declared in
  <mysql/plugin.h>.  Until the function is declared there, you can
  uncomment the buggy definition of mysql_tmpfile in ha_innodb.cc.
  
  Remove storage/innobase/*/Makefile.am.  The whole compilation is driven by
  storage/innobase/Makefile.am and storage/innobase/plug.in.
  
  plug.in: Declare InnoDB as a dynamic plugin.
  
  ha_innodb.h: Remove the declarations of many global variables.  The variables
  are no longer directly referenced outside of storage/innobase.
  
  trx_t: Add the field trx->duplicates.
  
  trx_create(): Initialize the fields trx->active_trans and trx->duplicates.
  
  innobase_query_is_update(): Remove.  Consult trx->duplicates instead.

storage/innobase/handler/ha_innodb.cc:
  Fixes after merging InnoDB snapshots.
  
  Revision r1422:
  Fix for Bug#21101 - returns wrong error message when table column
  defs exceed the max row size.
  
  The fix returns a more appropriate error message. Add a test case to
  innodb.test and expected output to innodb.result.
  
  
  Revision r1423:
  Fix for Bug#18828. Return DB_TOO_MANY_CONCURRENT_TRXS when we run out
  of UNDO slots in the rollback segment. This is a partial fix since the
  MySQL error code requested to properly report the error condition back
  to the client has not yet materialized. Currently we have #ifdef'd the
  error code translation in ha_innodb.cc. This will have to be changed
  as and when MySQl add the new requested code or an equivalent code
  that we can then use.
  
  Given the above, currently we will get the old behaviour, not the "fixed"
  and intended behaviour.
  
  
  
  Revision r1425:
  Fixed a missing function decoration that slipped into r1422.
  
  
  Revision r1434:
  Fix typo.
  
  
  Revision r1442:
  Potential fix for Bug#25645:
  
  "Move innobase_release_stat_resources(trx) outside the 'if' in
  ha_innobase::external_lock(). That would add more safety that whatever
  MySQL does at a query end, there would be no risk of a hang on the btr
  search latch."
  
  Also call innobase_release_temporary_latches() in the beginning of
  ha_innobase::close().
  
  Approved by:	Heikki
  
  
  Revision r1453:
  Bugfix: only call innobase_release_temporary_latches() in case of current_thd
  is not NULL, otherwise we get NULL pointer dereferencing.
  
  Approved by:	Heikki
  
  
  Revision r1474:
  Fix typo in comment: the exact prototype is in
  include/data0type.ic, not in data/data0type.ic
  
  
  
  Revision r1482:
  Fix Bug#25078 by always letting the replication thread on the slave
  server to enter InnoDB. This can be made further customizable by the
  user if we introduce a new config parameter. This will wait until
  config parameters can be easily added.

  Remove storage/innobase/*/Makefile.am.  The whole compilation is driven by

  plug.in: Declare InnoDB as a dynamic plugin.
  
  ha_innodb.h: Remove the declarations of many global variables.  The variables
  are no longer directly referenced outside of storage/innobase.
  
  trx_t: Add the field trx->duplicates.
  
  trx_create(): Initialize the fields trx->active_trans and trx->duplicates.
  
  innobase_query_is_update(): Remove.  Consult trx->duplicates instead.
  
  
  Revision r1489:
  thd_to_trx(), check_trx_exists(): Remove the handlerton parameter.  It is a
  singleton object whose address is stored into innodb_hton_ptr.
  
  
  Revision r1492:
  Convert innobase_buffer_pool_size and innobase_log_file_size types from
  longlong to long long because MYSQL_SYSVAR_LONGLONG marco expects long long
  type.
  
  Also change
  ((ulint)innobase_buffer_pool_size) / 1024
  to
  (ulint)(innobase_buffer_pool_size / 1024)
  and remove comment which is no longer true.
  
  Provided that innobase_buffer_pool_size is always 64bits these statements
  are equivalent if ulint is 64 bit (well it will screw up if
  innobase_buffer_pool_size is negative). And if ulint is 32 bit the later
  variant gives a little more chance that the value will fit.

  Revision r1493:
  ha_innodb.cc: Remove the declarations of some global InnoDB variables
  whose name starts with srv_.  These variables are declared in the header
  files that are covered by #include directives in ha_innodb.cc.
  
  
  Revision r1495:
  Introduce the function reset_template() for resetting some fields of
  row_prebuilt_t; currently prebuilt->read_just_key and
  prebuilt->keep_other_fields_on_keyread.
  
  
  Revision r1496:
  ha_innobase::extra(): Replace references to prebuilt->trx with
  thd_to_trx(ha_thd()), in order to avoid potential memory corruption.
  
  
  Revision r1501:
  Fix Bug#21293: Consider transactions that had edited non-transactional
  tables heavier than ones that had not. This helps killing the "right"
  transaction in case of a deadlock.
  
  Approved by:	Heikki
  
  
  Revision r1513:
  Split ut_a(a && b [&& c...]); into separate ut_a(a); ut_a(b); [ut_a(c); ...].
  This makes it possible to see which expression was false by looking at the
  error message.
  
  Approved by:	Marko
  
  
  Revision r1527:
  Cleanup in ha_innodb.cc:
  
  thd_is_replication_slave_thread(), thd_has_edited_nontrans_tables():
  Remove blank line between the function comment and the function
  definition.  There should be exactly one line between the return
  type and the function comment, and this line should be one of
  '', 'static', 'UNIV_INLINE', and 'extern "C"'.
  
  
  Revision r1538:
  Do not return error in ha_innobase::info if srv_force_recovery >= 4. This is to allow for 
  normal processing of the query by MySQL instead of generating an error.
  
  Reviewed by: Heikki
  
  
  
  Revision r1551:
  ha_innobase::innobase_read_and_init_auto_inc(): Remember and restore
  prebuilt->sql_stat_start.  In an ALTER TABLE statement in the innodb_gis
  test, an ut_ad() assertion failed, because no IX lock had been acquired
  on the table, because prebuilt->sql_stat_start was inadvertently reset
  to FALSE, by this function.  This function was called via
  ha_innobase::info() and mysql_prepare_alter_table().
