some platforms

Since the behavior of write(fd, buf, 0) is undefined, it may fail with
EFAULT on some architectures when buf == NULL. The error was propagated
up to a caller, since my_write() code did not handle it properly.

Fixed by checking the 'number of bytes' argument in my_write() and
returning before calling the write() system call when there is nothing
to write.


mysys/my_write.c:
  Return from my_write() before calling the write() system call when the
  number of bytes to be written is 0, since the behavior of write() in
  this case is not portable.

(compiler issue ?)

Problem:

Improper compile-time flags on AIX prevented use of files > 2 GB. This
resulted in Max_data_length being truncated to 2 GB by MyISAM code.

Solution:

Reverted large-file changes from the fix for bug10776. We need to define
_LARGE_FILES on AIX to have support for files > 2 GB.

 Since _LARGE_FILE_API is incompatible with _LARGE_FILES and may be
automatically defined by including standards.h, we also need a
workaround to avoid this conflict.


config/ac-macros/large_file.m4:
  Reverted large-file changes from the fix for bug10776. We need to define
  _LARGE_FILES on AIX to have support for files > 2 GB.
include/my_global.h:
  _LARGE_FILE_API is defined in standards.h that is automatically included
  by at least some C++ compilers on AIX. Since it is also incompatible
  with _LARGE_FILES which is required for POSIX IO calls to be
  largefile-safe, the only workaround is to explicitely #undef
  _LARGE_FILE_API.

Options to mysqld were not processed correctly because switch statement
was missing some "break"s. CS adds them.

No test case; would require .opt file and server restart. Manually tested.

fix is to check thd for NULL before using it.

  It is possible that mark_transaction_to_rollback() may be
  called in rare circumstances when thd is NULL (e.g., from
  some calls to convert_error_code_to_mysql()).  Don't use thd
  if it is NULL.

bitmap_is_set(table->write_set, fiel

Problem: creating a temporary table we allocate the group buffer if needed
followed by table bitmaps (see create_tmp_table()). Reserving less memory for 
the group buffer than actually needed (used) for values retrieval may lead 
to overlapping with followed bitmaps in the memory pool that in turn leads 
to unpredictable consequences.

As we use Item->max_length sometimes to calculate group buffer size,
it must be set to proper value. In this particular case 
Item_datetime_typecast::max_length is too small.

Another problem is that we use max_length to calculate the group buffer
key length for items represented as DATE/TIME fields which is superfluous.

Fix: set Item_datetime_typecast::max_length properly,
accurately calculate the group buffer key length for items 
represented as DATE/TIME fields in the buffer.

    - the group buffer key length for items represented as 
  DATE/TIME fields in the buffer should be calculated using
  the maximum pack length of such fields (== 8), using 
  max_length here is redundant.
