ec680f0a2b Fix for Bug#50221 Server refuses to start from non-default installdir on Solaris 32-bit
When starting mysqld it did not recognize most of the options given on
the command line when it was compiled for 32-bit Solaris using Sun
Studio compiler. The cause for this was that most of the entries in
the my_long_options array contained "garbage" data. The garbage data
was caused by a compiler bug. When initilizing the def_value member
for the "default-storage-engine" entry it was initialized like this:

  (longlong)"MyISAM"

i.e. casting a 32 bit pointer to a 64 bit integer value. Due to the
compiler bug only 4 bytes was allocated (instead of 8 bytes). This
caused everything following this entry to be stored at a location that
was 4 byte wrong.

The fix/work-around for this problem is initialize the def_value
for default-storage-engine in my_long_options to 0 and instead
initialize the default_storage_engine variable to "MyISAM" in
init_common_variables().

sql/mysqld.cc:
  Due to a bug in Sun Studio compiler when generating 32 bit code the 
  initialization of the def_value member of the default-storage-engine entry 
  in my_long_options only got 4 bytes allocated instead of 8 bytes. 
  The compiler bug was triggered by casting a 32 bit pointer to a 64 bit 
  integer value in the initialization code for my_long_options. To avoid 
  triggering the compiler bug the intialization of the def_value in
  my_long_options is set to 0 and instead the default_storage_engine
  is initialized to "MyISAM" in init_common_variables().

ac6b2605ff Addendum to the backport patch for WL#2934:
Unlike other platforms --mfpmath=sse is the default 
gcc mode on Mac OS X Intel. So it is unnecessary
to switch FPU to double precision mode (in fact,
it even breaks some math library functions).

12f364ece7 Backport of WL #2934: Make/find library for doing float/double
to string conversions and vice versa" 
Initial import of the dtoa.c code and custom wrappers around it 
to allow its usage from the server code. 
 
Conversion of FLOAT/DOUBLE values to DECIMAL ones or strings 
and vice versa has been significantly reworked. As the new 
algoritms are more precise than the older ones, results of such 
conversions may not always match those obtained from older 
server versions. This in turn may break compatibility for some 
applications. 
 
This patch also fixes the following bugs: 
- bug #12860 "Difference in zero padding of exponent between 
Unix and Windows" 
- bug #21497 "DOUBLE truncated to unusable value" 
- bug #26788 "mysqld (debug) aborts when inserting specific 
numbers into char fields" 
- bug #24541 "Data truncated..." on decimal type columns 
without any good reason"

cf9966f86f Fix for Bug#37408 - Compressed MyISAM files should not require/use mmap()
When compressed myisam files are opened, they are always memory mapped
sometimes causing memory swapping problems.

When we mmap the myisam compressed tables of size greater than the memory 
available, the kswapd0 process utilization is very high consuming 30-40% of 
the cpu. This happens only with linux kernels older than 2.6.9

With newer linux kernels, we don't have this problem of high cpu consumption
and this option may not be required.
 
The option 'myisam_mmap_size' is added to limit the amount of memory used for
memory mapping of myisam files. This option is not dynamic.

The default value on 32 bit system is 4294967295 bytes and on 64 bit system it
is 18446744073709547520 bytes.

Note: Testcase only tests the option variable. The actual bug has be to 
tested manually.

571843804c WL#5151: Conversion between different types when replicating
Row-based replication requires the types of columns on the
master and slave to be approximately the same (some safe
conversions between strings are allowed), but does not
allow safe conversions between fields of similar types such
as TINYINT and INT.

This patch implement type conversions between similar fields
on the master and slave.

The conversions are controlled using a new variable
SLAVE_TYPE_CONVERSIONS of type SET('ALL_LOSSY','ALL_NON_LOSSY').

Non-lossy conversions are any conversions that do not run the
risk of losing any information, while lossy conversions can
potentially truncate the value. The column definitions are
checked to decide if the conversion is acceptable.

If neither conversion is enabled, it is required that the
definitions of the columns are identical on master and slave.

Conversion is done by creating an internal conversion table,
unpacking the master data into it, and then copy the data to
the real table on the slave.

8969530cff Bug #45058 init_available_charsets uses double checked locking
As documented in the bug report, the double checked locking
pattern has inherent issues, and cannot guarantee correct
initialization.

This patch replaces the logic in init_available_charsets()
with the use of pthread_once(3). A wrapper function,
my_pthread_once(), is introduced and is used in lieu of direct
calls to init_available_charsets(). Related defines
MY_PTHREAD_ONCE_* are also introduced.

For the Windows platform, the implementation in lp:sysbench is
ported. For single-thread use, a simple define calls the
function and sets the pthread_once control variable.

Charset initialization is modified to use my_pthread_once().

include/my_no_pthread.h:
  Dummy my_pthread_once() for single thread use.
include/my_pthread.h:
  Declaration for new function my_pthread_once().
mysys/charset.c:
  Logic in init_available_charsets() is simplified. 
  Using my_pthread_once() for all calls to this func.
mysys/my_winthread.c:
  Windows implementation of my_pthread_once().

ba71a9e5d6 Bug #48742 Replication: incorrect help text for --init-slave
The help text for --init-slave=name:
"Command(s) that are executed when a slave connects to this master".
This text indicate that the --init-slave option is set on a  master 
server, and the master server passes the option's argument to slave 
which connects to it. This is wrong. Actually the --init-slave option 
just can be set on a slave server, and then the slave server executes 
the argument each time the SQL thread starts.

Correct the help text for --init-slave option as following:
"Command(s) that are executed by a slave server each time the SQL thread starts."


sql/mysqld.cc:
  Correct the help text for --init-slave option.

a4c50983f4 BUG#45292 orphan binary log created when starting server twice
This patch fixes three bugs as follows. First, aborting the server while purging
binary logs might generate orphan files due to how the purge operation was
implemented:

          (purge routine - sql/log.cc - MYSQL_BIN_LOG::purge_logs)

      1 - register the files to be removed in a temporary buffer.
      2 - update the log-bin.index.
      3 - flush the log-bin.index.
      4 - erase the files whose names where register in the temporary buffer
      in step 1.

Thus a failure while  executing step 4 would generate an orphan file. Second,
a similar issue might happen while creating a new binary as follows:

          (create routine - sql/log.cc - MYSQL_BIN_LOG::open)

      1 - open the new log-bin.
      2 - update the log-bin.index.

Thus a failure while executing step 1 would generate an orphan file.

To fix these issues, we record the files to be purged or created before really
removing or adding them. So if a failure happens such records can be used to
automatically remove dangling files. The new steps might be outlined as follows:

          (purge routine - sql/log.cc - MYSQL_BIN_LOG::purge_logs)

      1 - register the files to be removed in the log-bin.~rec~ placed in
      the data directory.
      2 - update the log-bin.index.
      3 - flush the log-bin.index.
      4 - delete the log-bin.~rec~.

          (create routine - sql/log.cc - MYSQL_BIN_LOG::open)

      1 - register the file to be created in the log-bin.~rec~
      placed in the data directory.
      2 - open the new log-bin.
      3 - update the log-bin.index.
      4 - delete the log-bin.~rec~.

          (recovery routine - sql/log.cc - MYSQL_BIN_LOG::open_index_file)

      1 - open the log-bin.index.
      2 - open the log-bin.~rec~.
      3 - for each file in log-bin.~rec~.
        3.1 Check if the file is in the log-bin.index and if so ignore it.
        3.2 Otherwise, delete it.

The third issue can be described as follows. The purge operation was allowing
to remove a file in use thus leading to the loss of data and possible
inconsistencies between the master and slave. Roughly, the routine was only
taking into account the dump threads and so if a slave was not connect the
file might be delete even though it was in use.

There should be indeed no Note present because there is in fact autoincrement
