Bug#36600 and Bug#36793:
Bug #36600 SHOW STATUS takes a lot of CPU in buf_get_latched_pages_number
Fix by removing the Innodb_buffer_pool_pages_latched variable from SHOW
STATUS output in non-UNIV_DEBUG compilation.
Bug #36793 rpl_innodb_bug28430 fails on Solaris
This is a back port from branches/zip. This code has been tested on a
big-endian machine too.

Fix Bug#35220 ALTER TABLE too picky on reserved word "foreign".
In ALTER TABLE, change the internal parser to search for
``FOREIGN[[:space:]]'' instead of only ``FOREIGN'' when parsing
ALTER TABLE ... DROP FOREIGN KEY ...; otherwise it could be mistaken
with ALTER TABLE ... DROP foreign_col;

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.

------------------------------------------------------------------------
Fixes:
- Bug #34920: auto_increment resets to 1 on foreign key creation
We need to use/inherit the passed in autoinc counter for ALTER TABLE
statements too.
Fixes the following bugs:
- 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
of the magic innodb_monitor tables and whether the user has enough rights
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.
- Bug #30930: Add auxiliary function to retrieve THD::thread_id
Add thd_get_thread_id() function. Also make check_global_access() function
visible to InnoDB under INNODB_COMPATIBILITY_HOOKS #define.
Fixes the following bug:
- Bug #32125: Database crash due to ha_innodb.cc:3896: ulint convert_search_mode_to_innobase
When unknown find_flag is encountered in convert_search_mode_to_innobase()
do not call assert(0); instead queue a MySQL error using my_error() and
return the error code PAGE_CUR_UNSUPP. Change the functions that call
convert_search_mode_to_innobase() to handle that error code by "canceling"
execution and returning appropriate error code further upstream.
The following bugs are fixed:
Bug #31860: Server crashes after inserting into InnoDB table with auto_increment column
In the Bug 16979 fix there was an erroneous assertion that
autoincrement columns can't contain negative values. With the fix, the
autoincrement table counter is set to 0 if the maximum value read from
the autoinc column index is negative.
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.
Bug #16979: AUTO_INC lock in InnoDB works a table level lock
Add a table level counter that tracks the number of AUTOINC locks that are
pending and/or granted on a table. We peek at this value to determine whether
a transaction doing a simple INSERT in innodb_autoinc_lock_mode = 1, needs to
acquire the AUTOINC lock or not. This change is related to Bug# 16979.
Bug #27950: Duplicate entry error in auto-inc after mysqld restart
We check whether the AUTOINC sub-system has been initialized (first) by
holding the AUTOINC mutex and if initialization is required then we
initialize using our normal procedure.
Bug #16979: AUTO_INC lock in InnoDB works a table level lock
- this is a major change in InnoDB auto-inc handling.
Bug #27950: Duplicate entry error in auto-inc after mysqld restart
- Init AUTOINC from delete_row().
Bug #28781: InnoDB increments auto-increment value incorrectly with ON DUPLICATE KEY UPDATE
- Use value specified by MySQL, in update_row().
Fixes:
- Bug #23710: crash_commit_before fails if innodb_file_per_table=1
- Bug #28254: innodb crash if shutdown during innodb_table_monitor is running
- Bug #28604: innodb_force_recovery restricts data dump
- Bug #29097: fsp_get_available_space_in_free_extents() is capped at 4TB
- Bug #29155: Innodb "Parallel recovery" is not prevented
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.

Fixes:
- Bug #21409: Incorrect result returned when in READ-COMMITTED with query_cache ON
At low transaction isolation levels we let each consistent read set
its own snapshot.
- Bug #23666: strange Innodb_row_lock_time_% values in show status; also millisecs wrong
On Windows ut_usectime returns secs and usecs relative to the UNIX
epoch (which is Jan, 1 1970).
- Bug #25494: LATEST DEADLOCK INFORMATION is not always cleared
lock_deadlock_recursive(): When the search depth or length is exceeded,
rewind lock_latest_err_file and display the two transactions at the
point of aborting the search.
- Bug #25927: Foreign key with ON DELETE SET NULL on NOT NULL can crash server
Prevent ALTER TABLE ... MODIFY ... NOT NULL on columns for which
there is a foreign key constraint ON ... SET NULL.
- Bug #26835: Repeatable corruption of utf8-enabled tables inside InnoDB
The bug could be reproduced as follows:
Define a table so that the first column of the clustered index is
a VARCHAR or a UTF-8 CHAR in a collation where sequences of bytes
of differing length are considered equivalent.
Insert and delete a record. Before the delete-marked record is
purged, insert another record whose first column is of different
length but equivalent to the first record. Under certain conditions,
the insertion can be incorrectly performed as update-in-place.
Likewise, an operation that could be done as update-in-place can
unnecessarily be performed as delete and insert, but that would not
cause corruption but merely degraded performance.
Add innodb_stats_on_metadata option, which enables gathering
index statistics when processing metadata commands such as
SHOW TABLE STATUS. Default behavior of the server does not
change (this option is enabled by default).
"Server Variables for Plugins"
Implement support for plugins to declare server variables.
Demonstrate functionality by removing InnoDB specific code from sql/*
New feature for HASH - HASH_UNIQUE flag
New feature for DYNAMIC_ARRAY - initializer accepts preallocated ptr.
Completed support for plugin reference counting.
Fixed compile-pentium64 scripts
Fixed wrong estimate of update_with_key_prefix in sql-bench
Merge bk-internal.mysql.com:/home/bk/mysql-5.1 into mysql.com:/home/my/mysql-5.1
Fixed unsafe define of uint4korr()

Small trivial cleanups
This also fixes a bug in counting number of rows that are updated when we have many simultanous queries
Move all connection handling and command exectuion main loop from sql_parse.cc to sql_connection.cc
Split handle_one_connection() into reusable sub functions.
Split create_new_thread() into reusable sub functions.
Added thread_scheduler; Preliminary interface code for future thread_handling code.
Use 'my_thread_id' for internal thread id's
Make thr_alarm_kill() to depend on thread_id instead of thread
Make thr_abort_locks_for_thread() depend on thread_id instead of thread
In store_globals(), set my_thread_var->id to be thd->thread_id.
Use my_thread_var->id as basis for my_thread_name()
The above changes makes the connection we have between THD and threads more soft.
Added a lot of DBUG_PRINT() and DBUG_ASSERT() functions
Fixed compiler warnings
Fixed core dumps when running with --debug
Removed setting of signal masks (was never used)
Made event code call pthread_exit() (portability fix)
Fixed that event code doesn't call DBUG_xxx functions before my_thread_init() is called.
Made handling of thread_id and thd->variables.pseudo_thread_id uniform.
Removed one common 'not freed memory' warning from mysqltest
Fixed a couple of usage of not initialized warnings (unlikely cases)
Suppress compiler warnings from bdb and (for the moment) warnings from ndb
Fixes:
- Bug #24712: SHOW TABLE STATUS for file-per-table showing incorrect time fields
- Bug #24386: Performance degradation caused by instrumentation in mutex_struct
