63574f1275 MDEV-11690 Remove UNIV_HOTBACKUP
The InnoDB source code contains quite a few references to a closed-source
hot backup tool which was originally called InnoDB Hot Backup (ibbackup)
and later incorporated in MySQL Enterprise Backup.

The open source backup tool XtraBackup uses the full database for recovery.
So, the references to UNIV_HOTBACKUP are only cluttering the source code.

71e11bce34 MDEV-8791 - AIX: Unresolved Symbols during linking
Clean-up nolock.h: it doesn't serve any purpose anymore. Appropriate code moved
to x86-gcc.h and my_atomic.h.

If gcc sync bultins were detected, we want to make use of them independently of
__GNUC__ definition. E.g. XLC simulates those, but doesn't define __GNUC__.

HS/Spider: According to AIX manual alloca() returns char*, which cannot be
casted to any type with static_cast. Use explicit cast instead.

MDL: Removed namemangling pragma, which didn't let MariaDB build with XLC.

WSREP: _int64 seem to be conflicting name with XLC, replaced with _integer64.

CONNECT: RTLD_NOLOAD is GNU extention. Removed rather meaningless check if
library is loaded. Multiple dlopen()'s of the same library are permitted,
and it never gets closed anyway. Except for error, which was a bug: it may
close library, which can still be referenced by other subsystems.

InnoDB: __ppc_get_timebase() is GNU extention. Only use it when __GLIBC__ is
defined.

Based on contribution by flynn1973.

2b47f8ff03 MDEV-10813 - Clean-up InnoDB atomics, memory barriers and mutexes
Clean-up periodic mutex/rwlock waiters wake up. This was a hack needed to
workaround broken mutexes/rwlocks implementation. We must have sane
implementations now and don't need these anymore: release thread is
guaranteed to wake up waiters.

Removed redundant ifdef that has equivalent code in both branches.

Removed os0atomic.h and os0atomic.ic: not used anymore.

Clean-up unused cmake checks.

f4d885c4e9 MDEV-10813 - Clean-up InnoDB atomics, memory barriers and mutexes
Replaced InnoDB atomic operations with server atomic operations.

Moved INNODB_RW_LOCKS_USE_ATOMICS - it is always defined (code won't compile
otherwise).

NOTE: InnoDB uses thread identifiers as a target for atomic operations.
Thread identifiers should be considered opaque: any attempt to use a
thread ID other than in pthreads calls is nonportable and can lead to
unspecified results.

MDEV-10547: Test multi_update_innodb fails with InnoDB 5.7

	The failure happened because 5.7 has changed the signature of
	the bool handler::primary_key_is_clustered() const
	virtual function ("const" was added). InnoDB was using the old
	signature which caused the function not to be used.

64824a760d MDEV-8684: UT_RELAX_CPU on Power to non-empty expansion
Using __ppc_get_timebase will translate to mfspr instruction
The mfspr instruction will block FXU1 until complete but the other
Pipelines are available for execution of instructions from other
SMT threads on the same core.

The latency time to read the timebase SPR is ~10 cycles.

So any impact on other threads is limited other FXU1 only instructions
(basically other mfspr/mtspr ops).

2877c5ecc2 MDEV-7477: Make innochecksum work on compressed tables
This patch ports the work that facebook has performed
to make innochecksum handle compressed tables.
the basic idea is to use actual innodb-code to perform
checksum verification rather than duplicating in innochecksum.cc.
to make this work, innodb code has been annotated with
lots of #ifndef UNIV_INNOCHECKSUM so that it can be
compiled outside of storage/innobase.

A new testcase is also added that verifies that innochecksum
works on compressed/non-compressed tables.

Merged from commit fabc79d2ea976c4ff5b79bfe913e6bc03ef69d42 
from https://code.google.com/p/google-mysql/

The actual steps to produce this patch are:

    take innochecksum from 5.6.14
    apply changes in innodb from facebook patches needed to make innochecksum compile
    apply changes in innochecksum from facebook patches
    add handcrafted testcase

1be4b121d5 Small Windows specific performance fixes:
- Use native memcmp() supplied with C runtime instead of hand-unrolled loop ptr_compare_N loop
Prior to fix  ptr_compare_0()  has  3.7% samples in OLTP-RO in-memory. 
Fix brings this down to 1.8% (all memcmp samples)

- Innodb : fix UT_RELAX_CPU to  be defined  as YieldProcessor, as  was also originally intended 
(but intention was lost in the #ifdef maze

This reduces number of ut_delay() samples in profile from 1.5% to 0.5%

67496884ae Bug 12323643 - CLEAN UP THE INNODB THREAD SHUTDOWN AND ASSERTIONS (WL#5136)
On shutdown, do not exit threads in os_event_wait(). This method of
exiting was only used by the I/O handler threads. Exit them on a
higher level.

os_event_wait_low(), os_event_wait_time_low(): Do not exit on shutdown.

os_thread_exit(), ut_dbg_assertion_failed(), ut_print_timestamp(): Add
attribute cold, so that GCC knows that these functions are rarely
invoked and can be optimized for size.

os_aio_linux_collect(): Return on shutdown.

os_aio_linux_handle(), os_aio_simulated_handle(), os_aio_windows_handle():
Set *message1 = *message2 = NULL and return TRUE on shutdown.

fil_aio_wait(): Return on shutdown.

logs_empty_and_mark_files_at_shutdown(): Even in very fast shutdown
(innodb_fast_shutdown=2), allow the background threads to exit, but
skip the flushing and log checkpointing.

innobase_shutdown_for_mysql(): Always wait for all the threads to exit.

e2e20a04df Fix the PAUSE instruction handling in InnoDB
Previously HAVE_IB_PAUSE_INSTRUCTION was never defined and thus InnoDB
never used the PAUSE instruction on non-windows even if it was available.
Probably the check was never migrated from autotools'
storage/innobase/plug.in to storage/innobase/CMakeLists.txt.

Since the check for PAUSE is done at top-level configure.cmake we can
use the result from there (HAVE_PAUSE_INSTRUCTION) instead of rolling
InnoDB's own HAVE_IB_PAUSE_INSTRUCTION (the check is identical anyway).

e2513bf07f Apply snapshot innodb-5.1-ss1989
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.

  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.

  Fix another compiler warning on Windows in InnoDB.
  
  ha_innodb.cc:
  
  Fix compiler warning: ::get_auto_increment takes a ulonglong
  for nb_desired_values, but InnoDB's trx struct stores it as
  a ulint (unsigned long).  Probably harmless, as a single
  statement won't be asking for more than 2^32 rows.
  
  
  Revision r1987:
  Bug fix: The problem was that when write_row() attempted to update the max
  autoinc value, and if it was rolled back because of a deadlock, the 
  deadlock error (transaction rollback) was not being propagated back to MySQL.

  ha_innodb.cc: fixed type conversion warnings revealed by bug 30639 
  
  
  Revision r1989:
  Suppress printing of deadlock errors while reading the autoinc value.
  DB_DEADLOCK errors are part of normal processing and excessive printing
  of these error messages could be disconcerting for users. 
  
  
  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.

  * Add (innodb|innobase|srv)_replication_delay MySQL config parameter.
  
  * Add UT_WAIT_FOR() macro that waits for a specified condition to occur

  Revision r1862:
  Add ut_snprintf() function. On Windows this needs to be implemented
  using auxiliary functions because there is no snprintf-variant on
  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 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.

  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).

  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.

  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().

d36f94791a Applied innodb-5.1-ss660 snapshot.
Changes in SQL parser:
 * Change default mode of SELECT from "lock in share mode"
   to "consistent read".
 * Remove support from SELECT for specifying "consistent read".
 * Add support in SELECT for specifying "lock in share mode".
 * Change all uses of SQL parser to specify "lock in share mode".
 * Modify syntax so that the only valid top-level statement is
   a procedure definition, since it's the only one that actually
   works.
 * Add support for lock waits.
