branches/5.1: fix bug#3139: Mysql crashes: 'windows error 995'
after several selects on a large DB
During stress environment, Windows AIO may fail with error code
ERROR_OPERATION_ABORTED. InnoDB does not handle the error, rather
crashes. The cause of the error is unknown, but likely due to
faulty hardware or driver.
This patch introduces a new error code OS_FILE_OPERATION_ABORTED,
which maps to Windows ERROR_OPERATION_ABORTED (995). When the error
is detected during AIO, the InnoDB will issue a synchronous retry
(read/write).
This patch has been extensively tested by MySQL support.

message:
BUG#42829: binlogging enabled for all schemas regardless of
binlog-db-db / binlog-ignore-db
InnoDB will return an error if statement based replication is used
along with transaction isolation level READ-COMMITTED (or weaker),
even if the statement in question is filtered out according to the
binlog-do-db rules set. In this case, an error should not be printed.
This patch addresses this issue by extending the existing check in
external_lock to take into account the filter rules before deciding to
print an error. Furthermore, it also changes decide_logging_format to
take into consideration whether the statement is filtered out from
binlog before decision is made.

This patch is mostly based on changes copied from branches/embedded-1.0,
mainly c5432, c3439, c3134, c2994, c2978, but also some other code was

Bug #48237 Error handling in os_mem_alloc_large appears to be incorrect
rb://198 Approved by: Marko
When scanning a directory readdir() is called and stat() after it,
if a file is deleted between the two calls stat will fail and the
whole precedure will fail. Change this behavior to continue with the
next entry if stat() fails because of nonexistent file. This is
transparent change as it will make it look as if the file was deleted
before the readdir() call.
This change is needed in order to fix
https://svn.innodb.com/mantis/view.php?id=174
in which we need to abort if os_file_readdir_next_file()
encounters "real" errors.

The changes are non-functional changes for normal InnoDB,
but needed for building the Hot Backup on Windows (with
UNIV_HOTBACKUP defined).

The call to put IO threads to sleep was most probably meant for Windows
only as the comment in buf0rea.c suggests. However it was enabled on
all platforms. This patch restricts the sleep call to windows. This
approach of not putting threads to sleep makes even more sense because
now we have multiple threads working in the background and it probably
is not a good idea to put all of them to sleep because a user thread
wants to post a batch for readahead.
Approved by: Marko
Enable functionality to have multiple background io helper threads.
This patch is based on percona contributions.
More details about this patch will be written at:
https://svn.innodb.com/innobase/MultipleBackgroundThreads
The patch essentially does the following:
expose following knobs:
innodb_read_io_threads = [1 - 64] default 1
innodb_write_io_threads = [1 - 64] default 1
deprecate innodb_file_io_threads (this parameter was relevant only on windows)
Internally it allows multiple segments for read and write IO request arrays
where one thread works on one segement.

Unprotected updates to ut_total_allocated_memory in
os_mem_alloc_large() and os_mem_free_large(), called during
fast index creation, may corrupt the variable and cause assertion failures.
Also, add UNIV_MEM_ALLOC() and UNIV_MEM_FREE() instrumentation around
os_mem_alloc_large() and os_mem_free_large(), so that Valgrind can
detect more errors.

All three srv_buf_pool related variables are defined as ulong, which is
32-bit on 64-bit Windows. They are changed to 64-bit ulint. Also
system_info.dwPageSize appears to be 32-bit only. Casting to 64-bit

The memory leak was due to wrong parameters passed into VirtualFree()
call. So, the call fails with Windows error 87. MEM_DECOMMIT can NOT be
used along with MEM_RELEASE. And if the parameter is MEM_RELEASE, the
size parameter must be 0. The function frees the entire region that is
reserved in the initial allocation call to VirtualAlloc.

lexyy.c, make_flex.sh: Declare yylex as UNIV_INTERN, not static. It is
referenced from pars0grm.c.
Actually, according to
nm .libs/ha_innodb.so|grep -w '[ABCE-TVXYZ]'
the following symbols are still global:
* The vtable for class ha_innodb
* pars0grm.c: The function yyparse() and the variables yychar, yylval, yynerrs
The required changes to the Bison-generated file pars0grm.c will be addressed
in a separate commit, which will add a script similar to make_flex.sh.
The class ha_innodb is renamed from class ha_innobase by a #define. Thus,
there will be no clash with the builtin InnoDB. However, there will be some
overhead for invoking virtual methods of class ha_innodb. Ideas for making
the vtable hidden are welcome. -fvisibility=hidden is not available in GCC 3.
