mysqlslap: setting --engine does not get replicated
http://bugs.mysql.com/bug.php?id=46967
and
mysqlslap: specifying --engine and --create does not
work with --engine=<storage_engine>:<option>
https://bugs.launchpad.net/maria/+bug/429773
Problems were that an --engine=<storage_engine> was translated
to a "set storage_engine = <storage_engine>", wich is _not_
replicated. A --engine=<storage_engine>:<option> was not always
properly parsed and in some cases crashed.
Fixed by eliminating "set storage_engine = ..." and adding
proper DDL generation. Initialized an unitialized buffer to
prevent crashes and fixed to use proper pointer for in
case of --engine=<storage_engine>:<option> being the last
element in list of --engines.
Also cleaned up code for better readability.
Q: Should MySQL's replication actually replicate a
"set storage_engine = ..." command or not?
A: No it should not. It is documented here:
http://dev.mysql.com/doc/refman/5.1/en/replication-features-variables.html
...
"The storage_engine system variable is not replicated, which is a
good thing for replication between different storage engines." ...
Before the patch, mysqlslap was behaving this way:
+-------------------------------+--------+-------------+
| | single | replication |
+-------------------------------+--------+-------------+

Option "--without-server" still not working in 5.1
The general approach is to make sure that source files
which require thread support are only compiled if the build
really needs thread support,
which means when the server is built or a thread-safe client
library.
This required several changes:
- Make sure the subdirectories "storage/" and "plugin/" are
only processed if the server is built, not ifclient-only.
- Make the compilation of some modules which inherently
require threading depend on thread supportin the build.
- Separate the handling of threading in "configure.in" from
that of server issues, threading is also needed in a
non-server build of a thread-safe client library.
Also, "libdbug" must get built even in a client-only build,
so "dbug/" must be in the list of client directories.
In addition, calls to thread functions in source files which
can be built without thread support must use the wrapper
functions which handle the non-threaded build.
So the modules "client/mysqlimport.c" and "client/mysqlslap.c"
must call "my_thread_end()" only via "mysql_thread_end()".
Makefile.am:
The directories "storage/" and "plugin/" contain files
which are needed for the server only, so their contents
is to be built only if a server is built.
They must not be named unconditionally, because building
their contents will fail unless threads are enabled.
These directories are now listed in the "configure"
variable "sql_server_dirs" which becomes part of
"sql_union_dirs" if the server is to be built.
client/mysqlimport.c:
Use the wrapper function "mysql_thread_end()" which
correctly handles the case of a non-threaded build.
client/mysqlslap.c:
Use the wrapper function "mysql_thread_end()" which
correctly handles the case of a non-threaded build.
configure.in:
Various changes to support builds "--without-server":
1) For the unit tests, we need "libdbug".
2) Separate the treatment of the server from that of the
thread-safe client library.
3) Introduce an "automake conditional" "NEED_THREAD"
which can be checked in some "Makefile.am".
4) Include "storage/" and "plugin/" in the list of
"sql_server_dirs" so that they are handled in the
top "Makefile.am" only if the server is to be built
(see the change in that file).
mysys/Makefile.am:
The code of "mf_keycache.c" in 5.1 is no longer safe
to be built without thread support.
(In 5.0, this was possible.)
Rather than fix these issues, which is tedious and risky,
avoid the need to ever build it without thread support:
It is needed in the server only, which needs thread support.
The only case where we build a "libmysys" without thread
support is for a non-threaded client, where "mf_keycache"
is not neded.
So its inclusion in the list of source files can depend
on the new conditional "NEED_THREAD".
unittest/mysys/Makefile.am:
Test program "my_atomic-t" is to verify the correct handling
of threads only, it cannot be built without thread support
and is not needed in such cases either.
Let its build depend on the new conditional "NEED_THREAD".
Option "--without-server" still not working in 5.1
The general approach is to make sure that source files
which require thread support are only compiled if the build
really needs thread support,
which means when the server is built or a thread-safe client
library.

Bug#24509 - 2048 file descriptor limit on windows needs increasing, also
WL#3049 - improved Windows I/O
The patch replaces the use of the POSIX I/O interfaces in mysys on Windows with
the Win32 API calls (CreateFile, WriteFile, etc). The Windows HANDLE for the open
file is stored in the my_file_info struct, along with a flag for append mode
because the Windows API does not support opening files in append mode in all cases)
The default max open files has been increased to 16384 and can be increased further
by setting --max-open-files=<value> during the server start.
Another major change in this patch that almost all Windows specific file IO code
has been moved to a new file my_winfile.c, greatly reducing the amount of code
in #ifdef blocks within mysys, thus improving readability.
Minor enhancements:
- my_(f)stat() is changed to use __stati64 structure with 64 file size
and timestamps. It will return correct file size now (C runtime implementation
used to report outdated information)
- my_lock on Windows is prepared to handle additional timeout parameter
- after review : changed __WIN__ to _WIN32 in the new and changed code.
client/mysqlbinlog.cc:
fileno -> my_fileno
client/readline.cc:
fileno -> my_fileno
include/config-win.h:
Increase OS_FILE_LIMIT for Windows.
Remove O_SHARE - Windows does not support it. Its definition conflicts with
O_SHORT_LIVED, that has different semantics.
include/my_dir.h:
Use stat64 for stat() family of functions on Windows, because of 64 bit file size.
include/my_global.h:
Increased default value for open file limit to 16K
include/my_sys.h:
- my_file_info got new structure members - file handle and open flags
- 2 new Windows-only mysys functions : my_get_osfhandle and my_osmaperr,
modelled after Windows C runtime functions _get_osfhandle and _dosmaperr
libmysql/CMakeLists.txt:
new files my_winfile.c and my_winerr.c
mysql-test/suite/large_tests/r/lock_tables_big.result:
test for more then 2048 open file descriptors on Windows
mysql-test/suite/large_tests/t/lock_tables_big.test:
test for more then 2048 open file descriptors on Windows
mysys/CMakeLists.txt:
new files my_winfile.c and my_winerr.c
mysys/Makefile.am:
new files my_winfile.c and my_winerr.c
mysys/default_modify.c:
fileno -> my_fileno
mysys/my_chsize.c:
implementation of chsize on Windows now moved to my_winfile.c
mysys/my_create.c:
- my_sopen->my_win_open
- close open file before removing (won't generally work on Windows otherwise)
mysys/my_file.c:
On Windows, files returned by my_open will not start with 0, but 2048
(making it simple to detect incompatible mix of CRT and mysys io functions)
mysys/my_fopen.c:
fileno->my_win_fileno , fclose->my_win_fclose, fdopen->my_win_fdopen
Check for legal filename is done by my_win_[f]open functions
mysys/my_fstream.c:
fileno->my_fileno
mysys/my_lib.c:
Windows stat() functions are moved to my_winfile.c
mysys/my_lock.c:
Move Windows code under #ifdef to a separate function win_lock().
Add a parameter for lock wait timeout
mysys/my_mmap.c:
_get_osfhandle->my_get_osfhandle
mysys/my_open.c:
my_sopen->my_win_open (simpler interface)
mysys/my_pread.c:
moved most windows specific code to my_win_file.c
Use my_win_pread
mysys/my_quick.c:
Use my_win_read/my_win_write
mysys/my_read.c:
Moved most of windows specific code to my_win_file.c
Use my_win_read()
mysys/my_seek.c:
On Windows, use my_win_lseek() in my_seek()/my_tell()
Removed dead code (synchronization of lseeks)
Improved DBUG tracing (file position is ulonglong, not ulong)
mysys/my_static.c:
Removed array initialization. my_file_info_default is global variable
thus it is initialized with all zeros anyway
mysys/my_sync.c:
_commit->my_win_fsync
mysys/my_winerr.c:
New file my_winerr.c
Exports my_osmaperr modelled after undocumented C runtime
function _dosmaperr(). The problem with _dosmaperr() used previously is that
1) it is nowhere documented and thus code relying on it is not guaranteed to work
in subsequent releases on the C runtime
2) it is present only in static C runtime (mysqld does not link if compiled with
/MD)
mysys/my_winfile.c:
New file my_winfile.c
Implements ANSI/Posix file IO routines, when possible using native Windows IO, without
C runtime (C runtime dropped because of the 2048 file descriptor limit).
mysys/my_write.c:
write->my_win_write
mysys/mysys_priv.h:
Declaration of Windows Posix functions (private to mysys, shall not be visible
outside)
storage/innobase/handler/ha_innodb.cc:
mysys native Windows IO : correct innodb tmp file handling
mysql_tmpfile does not return valid CRT file descriptor, thus
it is not possible to dup() it. Instead, the native file handle has
to be duplicated and then converted to CRT descriptor.
storage/myisam/mi_locking.c:
_commit->my_sync

* Finished Monty and Jani's merge
* Some InnoDB tests still fail (because it's old xtradb code run against
newer testsuite). They are expected to go after mergning with the latest
xtradb.
- Remove bothersome warning messages. This change focuses on the warnings
that are covered by the ignore file: support-files/compiler_warnings.supp.
- Strings are guaranteed to be max uint in length
