The reason for the error is incorrectly specified link dependencies
for mysql_embedded, mysqltest_embedded and mysql_client_test_embedded
in CMakeLists.txt (ADD_DEPENDENCIES should be TARGET_LINK_LIBRARIES)
libmysqld/CMakeLists.txt:
changed library type for libmysqld to SHARED instead of
MODULE. MODULE in CMake notation is a shared library that
is used only in dlopen/dlsym/LoadLibrary scenarios.
Hence it was impossible to use TARGET_LINK_LIBRARIES with
a MODULE.
libmysqld/examples/CMakeLists.txt:
Use TARGET_LINK_LIBRARIES (instead of previously incorrectly
used ADD_DEPENDENCIES) to specify link dependency from libmysqld
The problem here is that embedded server starts handle_thread manager
thread on mysql_library_init() does not stop it on mysql_library_end().
At shutdown, my_thread_global_end() waits for thread count to become 0,
but since we did not stop the thread it will give up after 5 seconds.
Solution is to move shutdown for handle_manager thread from kill_server()
(mysqld specific) to clean_up() that is used by both embedded and mysqld.
This patch also contains some refactorings - to avoid duplicate code,
start_handle_manager() and stop_handle_manager() functions are introduced.
Unused variables are eliminated. handle_manager does not rely on global
variable abort_loop anymore to stop (abort_loop is not set for embedded).
Note: Specifically on Windows and when using DBUG version of libmysqld,
the complete solution requires removing obsolete code my_thread_init()
from my_thread_var(). This has a side effect that a DBUG statement
after my_thread_end() can cause thread counter to be incremented, and
embedded will hang for some seconds. Or worse, my_thread_init() will
crash if critical sections have been deleted by the global cleanup
routine that runs in a different thread.
This patch also fixes and revert prior changes for Bug#38293
"Libmysqld crash in mysql_library_init if language file missing".
Root cause of the crash observed in Bug#38293 was bug in my_thread_init()
described above
client/mysql.cc:
sql_protocol_typelib is not exported from libmysqld
(does not make sense either)
thus excluded from embedded client
dbug/dbug.c:
revert changes for Bug#38293
include/my_dbug.h:
revert changes for Bug#38293
libmysql/libmysql.c:
Removed DBUG_POP call, because when called after my_end(), will access
THR_key_mysys that is already deleted. The result of pthread_get_specific
is not predictable in this case and hence DBUG_POP can crash.
libmysqld/examples/CMakeLists.txt:
Revert changes for Bug#38293.
libmysqld/lib_sql.cc:
code to start handle manager is factored out into
start_handle_manager() function
libmysqld/libmysqld.def:
Revert changes for Bug #38293
Remove excessive exports from libmysqld, export what API documents.
mysys/my_thr_init.c:
Remove windows-DLL-specific workaround for something (old code, no documentation for
what specifically). The problem is that even after my_thread_end() is finished,
DBUG statement can initiate my_thread_init(). This does not happen anywhere else and
should not happen on Windows either.
sql/mysql_priv.h:
- new functions start_handle_manager() and stop_handle_manager()
- move manager_thread_in_use variable to sql_manager.cc and made
it static
- remove manager_status, as it is unused
sql/mysqld.cc:
Code to start/stop handle_manager thread is factored out into start_handle_manager()
That's a Win-specific error.
When we create libmysqld.dll we have many libraries like mysys, dbug,
strings, etc linked into that dll, so the application built upon
this library shouldn't link these libraries to itself, rather use
those inside the dll.
Fixed by redirecting calls into the libmysqld.dll

Additional changes for bug#29903
- Changed to do embedded build part as normal build, when
WITH_EMBEDDED_SERVER is set.
- Allow both normal and debug build with embedded.
- Build static embedded library by pointing out all source and compile
it all, i.e. not building libraries from libraries, not portable.
- Let embedded use generated files from the "sql" directory, added
dependencies to make sure built before embedded.
- Mark library "dbug" in TARGET_LINK_LIBRARIES() with "debug", so only
linked in when debug target is used.
- Removed change of target name with "mysqld${MYSQLD_EXE_SUFFIX}", as
others can't depend on it, not defined at configure time. Instead
set the output file name.
- Created work around for bug in CMake 2.4.6 and output names, to
set the "mysqld<suffix>.pdb" name to the same base name.
- Set the correct manifest "name" (patch by iggy)
