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).

b05bf8ff0f Merge 10.1 to 10.2. 
Most notably, this includes MDEV-11623, which includes a fix and
an upgrade procedure for the InnoDB file format incompatibility
that is present in MariaDB Server 10.1.0 through 10.1.20.

In other words, this merge should address
MDEV-11202 InnoDB 10.1 -> 10.2 migration does not work

494e4b99a4 Remove MYSQL_TABLESPACES. 
MySQL 5.7 introduced partial support for user-created shared tablespaces
(for example, import and export are not supported).

MariaDB Server does not support tablespaces at this point of time.
Let us remove most InnoDB code and data structures that is related
to shared tablespaces.

70c11485d2 Remove MYSQL_ENCRYPTION. 
MariaDB will likely never support MySQL-style encryption for
InnoDB, because we cannot link with the Oracle encryption plugin.
This is preparation for merging MDEV-11623.

ab1e6fefd8 MDEV-11623 MariaDB 10.1 fails to start datadir created with 
MariaDB 10.0/MySQL 5.6 using innodb-page-size!=16K

The storage format of FSP_SPACE_FLAGS was accidentally broken
already in MariaDB 10.1.0. This fix is bringing the format in
line with other MySQL and MariaDB release series.

Please refer to the comments that were added to fsp0fsp.h
for details.

This is an INCOMPATIBLE CHANGE that affects users of
page_compression and non-default innodb_page_size. Upgrading
to this release will correct the flags in the data files.
If you want to downgrade to earlier MariaDB 10.1.x, please refer
to the test innodb.101_compatibility how to reset the
FSP_SPACE_FLAGS in the files.

NOTE: MariaDB 10.1.0 to 10.1.20 can misinterpret
uncompressed data files with innodb_page_size=4k or 64k as
compressed innodb_page_size=16k files, and then probably fail
when trying to access the pages. See the comments in the
function fsp_flags_convert_from_101() for detailed analysis.

Move PAGE_COMPRESSION to FSP_SPACE_FLAGS bit position 16.
In this way, compressed innodb_page_size=16k tablespaces will not
be mistaken for uncompressed ones by MariaDB 10.1.0 to 10.1.20.

Derive PAGE_COMPRESSION_LEVEL, ATOMIC_WRITES and DATA_DIR from the
dict_table_t::flags when the table is available, in
fil_space_for_table_exists_in_mem() or fil_open_single_table_tablespace().
During crash recovery, fil_load_single_table_tablespace() will use
innodb_compression_level for the PAGE_COMPRESSION_LEVEL.

FSP_FLAGS_MEM_MASK: A bitmap of the memory-only fil_space_t::flags
that are not to be written to FSP_SPACE_FLAGS. Currently, these will
include PAGE_COMPRESSION_LEVEL, ATOMIC_WRITES and DATA_DIR.

Introduce the macro FSP_FLAGS_PAGE_SSIZE(). We only support
one innodb_page_size for the whole instance.

When creating a dummy tablespace for the redo log, use
fil_space_t::flags=0. The flags are never written to the redo log files.

Remove many FSP_FLAGS_SET_ macros.

dict_tf_verify_flags(): Remove. This is basically only duplicating
the logic of dict_tf_to_fsp_flags(), used in a debug assertion.

fil_space_t::mark: Remove. This flag was not used for anything.

fil_space_for_table_exists_in_mem(): Remove the unnecessary parameter
mark_space, and add a parameter for table flags. Check that
fil_space_t::flags match the table flags, and adjust the (memory-only)
flags based on the table flags.

fil_node_open_file(): Remove some redundant or unreachable conditions,
do not use stderr for output, and avoid unnecessary server aborts.

fil_user_tablespace_restore_page(): Convert the flags, so that the
correct page_size will be used when restoring a page from the
doublewrite buffer.

fil_space_get_page_compressed(), fsp_flags_is_page_compressed(): Remove.
It suffices to have fil_space_is_page_compressed().

FSP_FLAGS_WIDTH_DATA_DIR, FSP_FLAGS_WIDTH_PAGE_COMPRESSION_LEVEL,
FSP_FLAGS_WIDTH_ATOMIC_WRITES: Remove, because these flags do not
exist in the FSP_SPACE_FLAGS but only in memory.

fsp_flags_try_adjust(): New function, to adjust the FSP_SPACE_FLAGS
in page 0. Called by fil_open_single_table_tablespace(),
fil_space_for_table_exists_in_mem(), innobase_start_or_create_for_mysql()
except if --innodb-read-only is active.

fsp_flags_is_valid(ulint): Reimplement from the scratch, with
accurate comments. Do not display any details of detected
inconsistencies, because the output could be confusing when
dealing with MariaDB 10.1.x data files.

fsp_flags_convert_from_101(ulint): Convert flags from buggy
MariaDB 10.1.x format, or return ULINT_UNDEFINED if the flags
cannot be in MariaDB 10.1.x format.

fsp_flags_match(): Check the flags when probing files.
Implemented based on fsp_flags_is_valid()
and fsp_flags_convert_from_101().

dict_check_tablespaces_and_store_max_id(): Do not access the
page after committing the mini-transaction.

IMPORT TABLESPACE fixes:

AbstractCallback::init(): Convert the flags.

FetchIndexRootPages::operator(): Check that the tablespace flags match the
table flags. Do not attempt to convert tablespace flags to table flags,
because the conversion would necessarily be lossy.

PageConverter::update_header(): Write back the correct flags.
This takes care of the flags in IMPORT TABLESPACE.

- Atomic writes are enabled by default
- Automatically detect if device supports atomic write and use it if
  atomic writes are enabled
- Remove ATOMIC WRITE options from CREATE TABLE
  - Atomic write is a device option, not a table options as the table may
    crash if the media changes

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.

8777458a6e MDEV-6076 Persistent AUTO_INCREMENT for InnoDB 
This should be functionally equivalent to WL#6204 in MySQL 8.0.0, with
the notable difference that the file format changes are limited to
repurposing a previously unused data field in B-tree pages.

For persistent InnoDB tables, write the last used AUTO_INCREMENT
value to the root page of the clustered index, in the previously
unused (0) PAGE_MAX_TRX_ID field, now aliased as PAGE_ROOT_AUTO_INC.
Unlike some other previously unused InnoDB data fields, this one was
actually always zero-initialized, at least since MySQL 3.23.49.

The writes to PAGE_ROOT_AUTO_INC are protected by SX or X latch on the
root page. The SX latch will allow concurrent read access to the root
page. (The field PAGE_ROOT_AUTO_INC will only be read on the
first-time call to ha_innobase::open() from the SQL layer. The
PAGE_ROOT_AUTO_INC can only be updated when executing SQL, so
read/write races are not possible.)

During INSERT, the PAGE_ROOT_AUTO_INC is updated by the low-level
function btr_cur_search_to_nth_level(), adding no extra page
access. [Adaptive hash index lookup will be disabled during INSERT.]

If some rare UPDATE modifies an AUTO_INCREMENT column, the
PAGE_ROOT_AUTO_INC will be adjusted in a separate mini-transaction in
ha_innobase::update_row().

When a page is reorganized, we have to preserve the PAGE_ROOT_AUTO_INC
field.

During ALTER TABLE, the initial AUTO_INCREMENT value will be copied
from the table. ALGORITHM=COPY and online log apply in LOCK=NONE will
update PAGE_ROOT_AUTO_INC in real time.

innodb_col_no(): Determine the dict_table_t::cols[] element index
corresponding to a Field of a non-virtual column.
(The MySQL 5.7 implementation of virtual columns breaks the 1:1
relationship between Field::field_index and dict_table_t::cols[].
Virtual columns are omitted from dict_table_t::cols[]. Therefore,
we must translate the field_index of AUTO_INCREMENT columns into
an index of dict_table_t::cols[].)

Upgrade from old data files:

By default, the AUTO_INCREMENT sequence in old data files would appear
to be reset, because PAGE_MAX_TRX_ID or PAGE_ROOT_AUTO_INC would contain
the value 0 in each clustered index page. In new data files,
PAGE_ROOT_AUTO_INC can only be 0 if the table is empty or does not contain
any AUTO_INCREMENT column.

For backward compatibility, we use the old method of
SELECT MAX(auto_increment_column) for initializing the sequence.

btr_read_autoinc(): Read the AUTO_INCREMENT sequence from a new-format
data file.

btr_read_autoinc_with_fallback(): A variant of btr_read_autoinc()
that will resort to reading MAX(auto_increment_column) for data files
that did not use AUTO_INCREMENT yet. It was manually tested that during
the execution of innodb.autoinc_persist the compatibility logic is
not activated (for new files, PAGE_ROOT_AUTO_INC is never 0 in nonempty
clustered index root pages).

initialize_auto_increment(): Replaces
ha_innobase::innobase_initialize_autoinc(). This initializes
the AUTO_INCREMENT metadata. Only called from ha_innobase::open().

ha_innobase::info_low(): Do not try to lazily initialize
dict_table_t::autoinc. It must already have been initialized by
ha_innobase::open() or ha_innobase::create().

Note: The adjustments to class ha_innopart were not tested, because
the source code (native InnoDB partitioning) is not being compiled.

* remove old 5.2+ InnoDB support for virtual columns
  * enable corresponding parts of the innodb-5.7 sources
  * copy corresponding test cases from 5.7
  * copy detailed Alter_inplace_info::HA_ALTER_FLAGS flags from 5.7
     - and more detailed detection of changes in fill_alter_inplace_info()
  * more "innodb compatibility hooks" in sql_class.cc to
     - create/destroy/reset a THD (used by background purge threads)
     - find a prelocked table by name
     - open a table (from a background purge thread)

  * different from 5.7:
    - new service thread "thd_destructor_proxy" to make sure all THDs are
      destroyed at the correct point in time during the server shutdown
    - proper opening/closing of tables for vcol evaluations in
       + FK checks (use already opened prelocked tables)
       + purge threads (open the table, MDLock it, add it to tdc, close
         when not needed)
    - cache open tables in vc_templ
    - avoid unnecessary allocations, reuse table->record[0] and table->s->default_values
    - not needed in 5.7, because it overcalculates:
      + tell the server to calculate vcols for an on-going inline ADD INDEX
      + calculate vcols for correct error messages

  * update other engines (mroonga/tokudb) accordingly

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.

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.

ec8257216e Enhancement: Change atomic_writes table option to enum type. Now every file can either use atomic writes, not use it or use default. 
SYNTAX: ATOMIC_WRITES=['DEFAULT','ON','OFF']

Idea here is to be able to define innodb_doublewrite = 1 but with following rules:

ATOMIC_WRITES='DEFAULT' - if innodb_use_atomic_writes = 1, we do not write to doublewrite buffer the changes
                          if innodb_use_atomic_writes = 0, we write to doublewrite buffer
ATOMIC_WRITES='ON'      - do not write to doublewrite buffer
ATOMIC_WRITES='OFF'     - write to doublewrite buffer

Note that doublewrite buffer can't be used if innodb_doublewrite = 0.

  branches/6.0: Allow the minimum length of a multi-byte character to be
  up to 4 bytes. (Bug #35391)

  dtype_t, dict_col_t: Replace mbminlen:2, mbmaxlen:3 with mbminmaxlen:5.
  In this way, the 5 bits can hold two values of 0..4, and the storage size
  of the fields will not cross the 64-bit boundary.  Encode the values as
  DATA_MBMAX * mbmaxlen + mbminlen.  Define the auxiliary macros
  DB_MBMINLEN(mbminmaxlen), DB_MBMAXLEN(mbminmaxlen), and
  DB_MINMAXLEN(mbminlen, mbmaxlen).

  Try to trim and pad UTF-16 and UTF-32 with spaces as appropriate.

  Alexander Barkov suggested the use of cs->cset->fill(cs, buff, len, 0x20).
  ha_innobase::store_key_val_for_row() now does that, but the added function
  row_mysql_pad_col() does not, because it doesn't have the MySQL TABLE object.

60d4288272 Check in the support for Information Schema System Table Views. Users 
can now view the content of InnoDB System Tables through following
information schema tables:

information_schema.INNODB_SYS_TABLES
information_schema.INNODB_SYS_INDEXES
information_schema.INNODB_SYS_COUMNS
information_schema.INNODB_SYS_FIELDS
information_schema.INNODB_SYS_FOREIGN
information_schema.INNODB_SYS_FOREIGN_COLS

7ceb29ff17 Renamed storage/innodb_plugin to storage/innobase, so that 1) it's the same 
layout as we always had in trees containing only the builtin
2) win\configure.js WITH_INNOBASE_STORAGE_ENGINE still works.

storage/innobase/CMakeLists.txt:
  fix to new directory name (and like 5.1)
storage/innobase/Makefile.am:
  fix to new directory name (and like 5.1)

b57e4dbd88 Creation of mysql-trunk = {summit + "Innodb plugin replacing the builtin"}: 
bzr branch mysql-5.1-performance-version mysql-trunk # Summit
cd mysql-trunk
bzr merge mysql-5.1-innodb_plugin # which is 5.1 + Innodb plugin 
bzr rm innobase # remove the builtin
Next step: build, test fixes.

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.

  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"

  Revision r1529:
  Revert r799, which was supposed to prevent similar cases as Bug#21638.
  In reality, the patch breaks the handling of prefix indexes of

  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 r1529:
  Revert r799, which was supposed to prevent similar cases as Bug#21638.
  In reality, the patch breaks the handling of prefix indexes of
  variable-length columns in ROW_FORMAT=COMPACT.  Reverting the patch
  is only a partial fix of Bug#28138.

  Revision r1424:
  Bug#20352. Added variable srv_insert_buffer_batch_size. We want to make
  this variable settable. Since the pluggable engine interface currently
  doesn't provide a usable mechanism, we will add the latter functionality
  once it's available.
  
  
  Revision r1426:
  Fix code indentation from r1424.
  
  
  Revision r1459:
  Fix typo in the comment.
  
  
  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.

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.

  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

  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().

innodb-5.1-ss1318
innodb-5.1-ss1330
innodb-5.1-ss1332
innodb-5.1-ss1340

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.

  Revision r1186:
  dict_load_foreign(): Use a local variable instead of the 10-bit field
  foreign->n_fields in order to preserve ON UPDATE CASCADE and
  ON DELETE CASCADE flags.  For some reason, gcc does not warn about
  shifting a 10-bit field to right by 24 bits.  (Bug 24741)
  
  This bug was introduced while reducing the memory footprint of the
  InnoDB data dictionary (Bug 20877).
  
  innodb.test, innodb.result: Add a test case.
  
  
  Revision r1318:
  Add a test case for r1316 (Bug #25927).
  
  
  Revision r1329:
  Merge changes from MySQL AB to mysql-test directives.
  The results are not affected.
  
  
  Revision r1340:
  innodb.test, innodb.result: Add test case for Bug #26835.
  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.

storage/innobase/btr/btr0btr.c:
  Applied innodb-5.1 snapshots ss799 and ss854
  
  Revision r823:
  Minor cleanup related to Bug #20877.
  
  btr_print_recursive(): Replace tree->tree_indexes with tree->index.
  This should have been done in r453.
  
  univ.i: Add UNIV_BTR_PRINT.
  
  rw_lock_t: Reduce writer_is_wait_ex to a bit and move it close to
  other bitfields.  Change the types to unsigned, in case ulint or ibool
  bitfields will not work.
  
  
  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)
  
  struct dict_tree_struct, dict_tree_t: Remove.
  
  struct dict_index_struct: Add page and lock.
  
  dict_tree_create(): Remove.  Replace the invocation with
  assignment to index->page and a call to rw_lock_create(&index->lock).
  
  dict_tree_free(): Remove.  Replace the invocation wtih
  a call to rw_lock_free(&index->lock).
  
  dict_index_get_tree(): Remove.
  
  dict_tree_get_space_reserve(): Rename to dict_index_get_space_reserve()
  and remove the parameter, which was unused.
  
  btr_level_list_remove(): Remove the unused parameter "tree".
  
  Replace the occurrences of "tree" with "index" in names of variables,
  functions and data types, e.g. "dict_tree_t tree" becomes
  "dict_index_t index".  Remove local variables "tree" or "index" of
  functions that needed both "tree" and "index".
  
  
  Revision r834:
  dict_col_t: Copy the fields of "dtype_t type" directly to this structure,
  so that all integer fields can be packed into 64 bits.  (Bug #20877)
  
  dtype_t: Change the type of all bit-fields to unsigned.
  
  dict_table_get_nth_col(), dict_table_get_sys_col_noninline(),
  dict_table_get_sys_col(), dict_field_get_col(): Return const
  dict_col_t*, so that changes to dict_col_t can be detected more
  easily.  Add const to many dict_col_t* declarations.
  
  dict_index_get_nth_type(): Replace with dict_index_get_nth_col().
  
  dict_col_get_type(): Replace with dict_col_copy_type().
  
  dict_col_get_min_size(), dict_col_get_max_size(), dict_col_get_fixed_size(),
  dict_col_get_sql_null_size(): New functions.
  
  dtype_get_at_most_n_mbchars(): Replace the parameter dtype
  with the parameters prtype, mbminlen, mbmaxlen.
  
  dtype_get_pad_char(), cmp_data_data(), cmp_data_data_slow(),
  cmp_whole_field(): Replace the dtype_t* parameter with the ulint
  parameters mtype, prtype.
  
  dtype_copy(): Add a const qualifier to type2 (the one being copied from).
  
  dtype_set_mblen(): Replaced with dtype_get_mblen().
  
  dtype_get_fixed_size_low(), dtype_get_min_size_low(),
  dtype_get_fixed_max_low(): Replace dtype_get_fixed_size(),
  dtype_get_min_size(), and dtype_get_max_size().  These are used by the
  dict_col_get_{fixed,min,max}_size() functions.
  
  cmp_types_are_equal(): Replace with cmp_cols_are_equal().
  
  dict_table_get_col_name(): Add a const qualifier parameter to the
  parameter "table".
  
  dtype_binary, dtype_binary_val: Remove.
  
  dtype_is_fixed_size(): Remove.
  
  
  Revision r837:
  page_offset(): New function to replace many ut_align_offset(., UNIV_PAGE_SIZE)
  calls.
  
  dict_index_build_node_ptr(): Correct a typo in a comment.
  
  
  Revision r838:
  Revamp the line splits done in r763 and r764 that can now be done better,
  thanks to r826.

  dtype_t: Remove unused field "prec", which was supposed to be used for
  the precision of decimal columns in stand-alone InnoDB.
  
  dtype_get_prec(): Remove.
  
  dtype_set(), dict_mem_table_add_col(): Remove parameter "prec".
  
  dtype_t: Turn all fields (mtype, prtype, len, mbminlen, mbmaxlen, len)
  into bit-fields.
  
  dict_table_t, dict_index_t, dict_tree_t: Omit magic_n from non-debug builds.
  
  dict_col_t: Turn ind, clust_pos, and ord_part into bit-fields.
  
  Replace the default clust_pos value ULINT_UNDEFINED with
  REC_MAX_N_FIELDS and replace all references to clust_pos with calls to
  the accessor function dict_col_get_clust_pos().
  
  dict_field_t: Turn prefix_len and fixed_len into bit-fields.
  
  dict_tree_t: Remove pad[64].
  
  dict_table_t: Turn the fields ibd_file_missing, tablespace_discarded,
  cached, flags, stat_initialized, and autoinc_inited into bit-fields.
  Remove does_not_fit_in_memory from non-debug builds.

  (Bug #20877)
  
  We could shrink the structure further to three 32-bit words or two
  64-bit words by turning the remaining fields to bit-fields.
  Unfortunately, the fields are not protected by any mutex, and thus we
  would better keep each field aligned to a machine word.
  
  btr_search_t, buf_block_t: Rename "ulint side" to "ibool left_side".

  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256

  Revision r832:
  Add dict_table_get_col_name() in preparation for getting rid of

  Revision r833:
  Tweak the bit-field definitions introduced since r813 to address Bug #20877.
  
  rw_lock_t: Do not make writer_is_wait_ex a bit-field.  There are no fields
  yet that could be fused to the same machine word, but we play it safe,
  because the field writer_is_wait_ex may be modified by several threads
  simultaneously.  Such fields should always be allocated an own machine
  word.
  
  dict_table_t: Change the type of all bit-fields to "unsigned".  Make
  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.
  
  dict_build_table_def_step(): Pass a local variable to
  fil_create_new_single_table_tablespace() and initialize table->space
  from it after the call, now that table->space is a bit-field.
  
  
  Revision r834:
  dict_col_t: Copy the fields of "dtype_t type" directly to this structure,

  dict_table_get_nth_col(), dict_table_get_sys_col_noninline(),
  dict_table_get_sys_col(), dict_field_get_col(): Return const
  dict_col_t*, so that changes to dict_col_t can be detected more
  easily.  Add const to many dict_col_t* declarations.

  Remove dict_col_t::hash, dict_col_t::table,

  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),
  dict_col_remove_from_cache(): Remove.  These only updated dict_sys->col_hash.
  
  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.

  dict_col_get_clust_pos(): Add parameter clust_index.  Replace the
  look-up with a linear search of all columns in the clustered index.
  
  row_upd_index_replace_new_col_vals(): Compute clust_index outside
  the loops.  Compute clust_pos outside the inner loop.

  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.

  Revision r828:
  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)

  functions that needed both "tree" and "index".

  Remove dict_col_t::hash, dict_col_t::table,
  dict_sys->col_hash, and DICT_POOL_PER_COL_HASH.  (Bug #20877)
  
  The col->table pointer was only needed for maintaining a hash table of
  all defined columns in all tables.  The hash table was only looked up
  in dict_index_find_cols().  Removing the col->hash and col->table
  pointers reduces the size of a table column by two machine words
  (usually 8 or 16 bytes).
  
  dict_col_add_to_cache(), dict_col_reposition_in_cache(),
  dict_col_remove_from_cache(): Remove.  These only updated dict_sys->col_hash.
  
  dict_index_find_cols(): Use a linear search instead of the hash table.
  The time complexity is affected, but this function is only invoked by
  dict_index_add_to_cache(), and we only search the columns of a single
  table (typically at most a few dozen) as opposed to all columns of all
  tables.

  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256

  simultaneously.  Such fields should always be allocated an own machine
  word.

  "space" a bit-field of 32 bits.  Move name_hash and id_hash after all
  bit-fields, so that the bit-fields can be allocated together.  Do not
  make autoinc_inited a bit-field, as we cannot allocate any field
  from the same machine word.

  Remove dict_tree_t, which should have been removed in r453.
  There always was a one-to-one mapping between dict_tree_t and dict_index_t.
  
  This saves 6 machine words per B-tree index in the data dictionary
  cache plus the memory allocation overhead.  We save one mem_heap_t
  object per index (15 machine words).  Considering the internal
  fragmentation of the buddy allocator in mem_area_alloc(), this should
  save 32 machine words per index (128 bytes on 32-bit systems and 256
  bytes on 64-bit systems).  (Bug #20877)
