It used to be declared as ulint, which is 32/64 bit integer depending on OS bitness.
However this declaration lead to problems with os_compare_and_swap_thread_id
implementation which operated on 32 bit integers (InterlockedCompareExchange)
Using 64 bit int lead to wrong result in os_compare_and_swap_thread_id
and to crash/assertion in rw_lock_set_writer_id_and_recursion_flag()
The fix is to use 4 byte integer to os_thread_id type definition.

BUG#42101 - Race condition in innodb_commit_concurrency

that innodb_commit_concurrency>0 remains constant at run time. (Bug #42101)
srv_commit_concurrency: Make this a static variable in ha_innodb.cc.
innobase_commit_concurrency_validate(): Check that innodb_commit_concurrency
is not changed from or to 0 at run time. This is needed, because
innobase_commit() assumes that innodb_commit_concurrency>0 remains constant.
Without this limitation, the checks for innodb_commit_concurrency>0
in innobase_commit() should be removed and that function would have to
acquire and release commit_cond_m at least twice per invocation.
Normally, innodb_commit_concurrency=0, and introducing the mutex operations
would mean significant overhead.

When using the random function, first take the modulus by the number of pages
and then typecast to ulint.
This is a followup to r4699 - the fix of Bug#43660.
Occasionally, if both the partition_pruning
and partition_range tests are run sequentially
against the IBMDB2I engine, the partition_range
test will fail.
Compiler padding on a 64-bit build allowed
garbage data in the hash key used for
caching open iconv descriptors. As a
result, cached descriptors were not found,
and multiple duplicate iconv descriptors
were opened for a single character set.
Eventually, the maximum number of open
iconv descriptors was reached, and further
iconv_open() calls would fail, leading the
storage engine to report incorrectly that
the character set was not supported.
This patch widens the 16-bit members of the
hash key to 32 bits to eliminate compiler
padding. The entire length of the hash key
is now initialized correctly on both 32-bit
and 64-bit builds.
storage/ibmdb2i/db2i_charsetSupport.cc:
Bug#44856 IBMDB2I gives misleading 2504 error
widen the 16-bit members of the
hash key to 32 bits to eliminate
compiler padding.
In order to better support the usage of
IBMDB2I tables from within RPG programs,
the storage engine should ensure that the
RCDFMT name is consistent and predictable
for DB2 tables.
This patch appends a "RCDFMT <name>"
clause to the CREATE TABLE statement
that is passed to DB2. <name> is
generated from the original name of
the table itself. This ensures a
consistent and deterministic mapping
from the original table.
For the sake of simplicity only
the alpha-numeric characters are
preserved when generating the new
name, and these are upper-cased;
other characters are replaced with
an underscore (_). Following DB2
system identifier rules, the name
always begins with an alpha-character
and has a maximum of ten characters.
If no usable characters are found in
the table name, the name X is used.

When a user selected an unsupported character set for an

The storage engine was not correctly handling the case in
which rnd_pos is executed for a handler without a preceding
rnd_next or index read operation. As a result, an unitialized
file handle was sometimes being passed to the QMY_READ API.
The fix clears the rrnAssocHandle at the beginning of each
read operation and then checks to see whether it has been
set to a valid handle value before attempting to use it
in rnd_pos. If rrnAssocHandle has not been set by a previous
read operation, rnd_pos instead falls back to the use of the
currently active handle.

Revert a change to Makefile.am that I committed accidentally in c4574.
On IBM i 5.4, schemas with names that are longer
than 8 characters and contain digits or an underscore
cannot contain IBMDB2I tables, even though this should
theoritically be possible if all alpha characters
are uppercase.
THe current patch fixes the IBMDB2I engine to
allow digits and the underscore(_) to be used in
schema names longer than 8 characters on IBM i 5.4.
storage/ibmdb2i/db2i_misc.h:
The function which detected whether the
operating system would treat a schema as an "ordinary identifier" (allowing 10 characters in the name instead of 8) did not cover all possible cases.Function was
renamed and enhanced to detect all
possible cases of "ordinary identifiers".
storage/ibmdb2i/ha_ibmdb2i.cc:
use the renamed function to cover all
possible cases of ordinary identifiers.
In some circumstances, when a table is created with
the IBMDB2I engine, the CREATE TABLE statement will
return successfully but the table will not exist.
The current patch addresses the above issue and causes
CREATE to fail and report and error to the user.
storage/ibmdb2i/ha_ibmdb2i.cc:
Locally declared return code hid function-
scoped declaration and went out of scope
before being returned. Removed inner
declaration.
The utf8_swedish_ci and ucs2_swedish_ci
collations do not work with indexes on
IBMDB2I tables.
The current patch adds the mapping for
ucs2_swedish collation and removes the
ucs2_spanish2 mapping which is not
supported by any version of the operating
system.
storage/ibmdb2i/db2i_collationSupport.cc:
Removed mapping for ucs2_spanish2 collation
since it is not supported by any version of the operating system. Added mapping for ucs2_swedish
collation which had been overlooked but is
supported by the IBM i 6.1.
Currently the memory map is being created
with a size that is greater than the size
of the underlying datafile. This can cause
varying behaviour,
e.g.
In windows the size of the datafile
is increased, while on linux it remains
the same.
This fix removes the increment margin to
the size that is used while creating the
memory map.
storage/myisam/mi_dynrec.c:
remove MEMMAP_EXTRA_MARGIN that is used as
the increment margin to the underlying
datafile size while creating the mmap.
storage/myisam/mi_packrec.c:
The size of the underlying datafile is
increased by MEMMAP_EXTRA_MARGIN when
using a packed record format. Hence in
this case the size of the memory map should
be incremented by the same factor.
The conformance checker was not taking into
account, and, making concessions for acceptable
incompatibilites in tables created by
versions earlier than 4.1.
The current patch relaxes the conformance
checker to ignore differences in key_alg
and language for tables created by versions
earlier than 4.1.
storage/myisam/ha_myisam.cc:
Modify check_definition to ignore differences
in key_alg and language for tables created
by versions earlier than 4.1.
