"Rows not deleted from innodb partitioned tables if --innodb_autoinc_lock_mode=0"
Due to a previous bugfix which initializes a previously uninitialized
variable, ha_partition::get_auto_increment() may fail to operate
correctly when the storage engine reports that it is only reserving
one value and one or more partitions have a different 'next-value'.
Currently, only affects Innodb's new-style auto-increment code which
reserves larger blocks of values and has less inter-thread contention.

Ensure that innobase_read_and_init_auto performs table autoinc lock when lock_mode = 0
No need for "if" guard around row_unlock_table_autoinc_for_mysql() because
it already performs same check.
Make autoinc_lock_mode variable read-only for duration of running mysqld process.
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().
Additional changes for bug#29903
- Changed to do embedded build part as normal build, when
WITH_EMBEDDED_SERVER is set.
- Allow both normal and debug build with embedded.
- Build static embedded library by pointing out all source and compile
it all, i.e. not building libraries from libraries, not portable.
- Let embedded use generated files from the "sql" directory, added
dependencies to make sure built before embedded.
- Mark library "dbug" in TARGET_LINK_LIBRARIES() with "debug", so only
linked in when debug target is used.
- Removed change of target name with "mysqld${MYSQLD_EXE_SUFFIX}", as
others can't depend on it, not defined at configure time. Instead
set the output file name.
- Created work around for bug in CMake 2.4.6 and output names, to
set the "mysqld<suffix>.pdb" name to the same base name.
- Set the correct manifest "name" (patch by iggy)
They had been introduced in 5.1 and were only later backported to 5.0;
as a consequence, the files in the 5.1 tree do not depend on the 5.0 ones,
and changes in 5.0 do not propagate into the 5.1 files.
To fix this, the (previous) files in 5.1 now are deleted ("bk rm"),
and the previously deleted files depending on 5.0 are now moved to the
respective source directories ("bk mv").
The current 5.1 contents is restored in these files.
If you need the previous history of the 5.1 files ("bk revtool"),
access those in "BitKeeper/deleted".
Contrary to the original plan, I did not introduce the name
"CMakeLists.historic" - mostly in order not to clutter the source tree.
This fixes bug#29982.
for enabling threads. However, duplicate AC_PROG_* macros in the
innobase plug.in file were resetting $CC and causing link errors.
As AC_PROG_* macros are already used in the main configure.in file
there should be no need for them to be duplicated here too.
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.

Add more accessors to MySQL internals in mysql/plugin.h, for storage
engine plugins.
Add some accessors specific to the InnoDB storage engine, to allow
InnoDB to be compiled as a plugin (without MYSQL_SERVER). InnoDB
has additional requirements, due to its foreign key support, etc.
- Add build configuration parameter EMBEDDED_ONLY which will configure
the VS solution to produce only mysql embedded binary.
- Make necessary updates to successfully compile solution.
replication):
Patch to add binlog format capabilities to the InnoDB storage engine.
The engine will not allow statement format logging when in READ COMMITTED
or READ UNCOMMITTED transaction isolation level.
In addition, an error is generated when trying to use READ COMMITTED
or READ UNCOMMITTED transaction isolation level in STATEMENT binlog
mode.
The following type conversions was done:
- Changed byte to uchar
- Changed gptr to uchar*
- Change my_string to char *
- Change my_size_t to size_t
- Change size_s to size_t
Removed declaration of byte, gptr, my_string, my_size_t and size_s.
Following function parameter changes was done:
- All string functions in mysys/strings was changed to use size_t
instead of uint for string lengths.
- All read()/write() functions changed to use size_t (including vio).
- All protocoll functions changed to use size_t instead of uint
- Functions that used a pointer to a string length was changed to use size_t*
- Changed malloc(), free() and related functions from using gptr to use void *
as this requires fewer casts in the code and is more in line with how the
standard functions work.
- Added extra length argument to dirname_part() to return the length of the
created string.
- Changed (at least) following functions to take uchar* as argument:
- db_dump()
- my_net_write()
- net_write_command()
- net_store_data()
- DBUG_DUMP()
- decimal2bin() & bin2decimal()
- Changed my_compress() and my_uncompress() to use size_t. Changed one
argument to my_uncompress() from a pointer to a value as we only return
one value (makes function easier to use).
- Changed type of 'pack_data' argument to packfrm() to avoid casts.
- Changed in readfrm() and writefrom(), ha_discover and handler::discover()
the type for argument 'frmdata' to uchar** to avoid casts.
- Changed most Field functions to use uchar* instead of char* (reduced a lot of
casts).
- Changed field->val_xxx(xxx, new_ptr) to take const pointers.
Other changes:
- Removed a lot of not needed casts
- Added a few new cast required by other changes
- Added some cast to my_multi_malloc() arguments for safety (as string lengths
needs to be uint, not size_t).
- Fixed all calls to hash-get-key functions to use size_t*. (Needed to be done
explicitely as this conflict was often hided by casting the function to
hash_get_key).
- Changed some buffers to memory regions to uchar* to avoid casts.
- Changed some string lengths from uint to size_t.
- Changed field->ptr to be uchar* instead of char*. This allowed us to
get rid of a lot of casts.
- Some changes from true -> TRUE, false -> FALSE, unsigned char -> uchar
- Include zlib.h in some files as we needed declaration of crc32()
- Changed MY_FILE_ERROR to be (size_t) -1.
- Changed many variables to hold the result of my_read() / my_write() to be
size_t. This was needed to properly detect errors (which are
returned as (size_t) -1).
- Removed some very old VMS code
- Changed packfrm()/unpackfrm() to not be depending on uint size
(portability fix)
- Removed windows specific code to restore cursor position as this
causes slowdown on windows and we should not mix read() and pread()
calls anyway as this is not thread safe. Updated function comment to
reflect this. Changed function that depended on original behavior of
my_pwrite() to itself restore the cursor position (one such case).
- Added some missing checking of return value of malloc().
- Changed definition of MOD_PAD_CHAR_TO_FULL_LENGTH to avoid 'long' overflow.
- Changed type of table_def::m_size from my_size_t to ulong to reflect that
m_size is the number of elements in the array, not a string/memory
length.
- Moved THD::max_row_length() to table.cc (as it's not depending on THD).
Inlined max_row_length_blob() into this function.
- More function comments
- Fixed some compiler warnings when compiled without partitions.
- Removed setting of LEX_STRING() arguments in declaration (portability fix).
- Some trivial indentation/variable name changes.
- Some trivial code simplifications:
- Replaced some calls to alloc_root + memcpy to use
strmake_root()/strdup_root().
- Changed some calls from memdup() to strmake() (Safety fix)
- Simpler loops in client-simple.c
