When a transaction joins we check if there are any other transactions
waiting on its locks. If there aren't any waiting then no deadlock can
occur. This patch however has additional changes.
1. Count leading zeros
2. Count trailing zeros
There are two version of both these utility functions. One is hand
coded and the other will use the GCC builtin when available. The
changes to configure have yet to be made.
Simplify the next record lock fetch in the deadlock check code.
Pass the heap number as a parameter to the deadlock check code.

This patch:
- Moves all definitions from the mysql_priv.h file into
header files for the component where the variable is
defined
- Creates header files if the component lacks one
- Eliminates all include directives from mysql_priv.h
- Eliminates all circular include cycles
- Rename time.cc to sql_time.cc
- Rename mysql_priv.h to sql_priv.h
BUG#46364 introduced the flag binlog_direct_non_transactional_updates which
would make N-changes to be written to the binary log upon committing the
statement when "ON". On the other hand, when "OFF" the option was supposed
to mimic the behavior in 5.1. However, the implementation was not mimicking
the behavior correctly and the following bugs popped up:
Case #1: N-changes executed within a transaction would go into
the S-cache. When later in the same transaction a
T-change occurs, N-changes following it were written
to the T-cache instead of the S-cache. In some cases,
this raises problems. For example, a
Table_map_log_event being written initially into the
S-cache, together with the initial N-changes, would be
absent from the T-cache. This would log N-changes
orphaned from a Table_map_log_event (thence discarded
at the slave). (MIXED and ROW)
Case #2: When rolling back a transaction, the N-changes that
might be in the T-cache were disregarded and
truncated along with the T-changes. (MIXED and ROW)
Case #3: When a MIXED statement (TN) is ahead of any other
T-changes in the transaction and it fails, it is kept
in the T-cache until the transaction ends. This is
not the case in 5.1 or Betony (5.5.2). In these, the
failed TN statement would be written to the binlog at
the same instant it had failed and not deferred until
transaction end. (SBR)
To fix these problems, we have decided to do what follows:
For Case #1 and #2, we circumvent them:
1. by not letting binlog_direct_non_transactional_updates
affect MIXED and RBR. These modes will keep the behavior
provided by WL#2687. Although this will make Celosia to
behave differently from 5.1, an execution will be always
safe under such modes in the sense that slaves will never
go out sync. In 5.1, using either MIXED or ROW while
mixing N-statements and T-statements was not safe.
For Case #3, we don't actually fix it. We:
1. keep it and make all MIXED statements whether they end
up failing or not or whether they are up front in the
transaction or after some transactional change to always
be stored in the T-cache. This means that it is written
to the binary log on transaction commit/rollback only.
2. We make the warning message even more specific about the
MIXED statement and SBR.

the upper limit of total rollback segments from 256 to 128. This is because
we can't use the sign bit. It has not caused problems in the past because we
only created one segment. InnoDB has always had the capability to use the
additional rollback segments therefore this patch is backwards compatible.
The only requirement to maintain backward compatibility has been to ensure
that the additional segments are created after the double write buffer.
This is to avoid breaking assumptions in the existing code.

noted that the check for ignore_secondary_unique might not be disabled
for deletes. Indeed, I see no reason for the check to exist for deletes.
btr_op_enum: Document the constants. Add BTR_INSERT_IGNORE_UNIQUE_OP.
btr_cur_search_to_nth_level(): Remove the variable
ignore_sec_unique. Use btr_op instead. Invoke ibuf_should_try() with
ignore_sec_unique = (btr_op != BTR_INSERT_OP), that is, always ignore
the UNIQUE constraint when buffering delete-mark and purge.
BTR_IGNORE_SEC_UNIQUE: Note that the flag only makes sense in
conjunction with BTR_INSERT.
rb://274 approved by Sunny Bains. This addresses Issue #471.
The adaptive hash index can be used when a buffered operation is requested,
and the latch_mode check does not prevent it, because latch_mode does not
contain any btr_op bits at this point.

Check in code change for implementing Performace Schema in InnoDB.
Objects in four different modules in InnoDB have been performance
instrumented, these modules are:
1) mutexes
2) rwlocks
3) file I/O
4) threads
We mostly preserved the existing APIs, but APIs would point to
instrumented function wrappers if performance schema is defined.
There are 4 different defines that controls the instrumentation of
each module. The feature is off by default, and will be compiled in
with special build option, and requre configure option to turn it on
when server boots. For more detail design and functional information,
please refer to performance schema wiki page.

debug_max
There was a buffer overrun when unpacking the date
field. Incidentaly, this seems to affect only solaris x86_64
debug builds, but others platforms may be vulnerable as well.
In particular, the buffer size used was not taking into
consideration that the '\0' character would be written into
it.
We fix this by increasing the size of the buffer used to
accommodate one extra byte (the one for the '\0').
which was detected during the build of 5.5.3-m3.
This requires version 9 of IBM C++ to help.
More fixes will still be needed, it is very strict
(or rather: a bit picky?) about templates.
linux x86_64 max
Rpl tests were surprisingly taking too long when server was built
using cmake on linux. This was because cmake counter part of
patch for WL#4949 was not defining SIGNAL_WITH_VIO_CLOSE flag,
which had negative impact on the time needed to stop the slave IO
thread on STOP SLAVE command.
We fix this by deploy the missing SET command on configure.cmake.

archive storage engine headers don't include my_global.h first
During the build of 5.5.3-m3 on older Linux platforms
(kernels 2.4 or early 2.6),
the symptom described in the bug report occurred both
in the "archive" and in the "innobase" storage engine.
This change is the patch proposed in that bug report,
and a similar one in innobase, that latter is aligned
with Vasil Dimov of Innobase, the original author.
