2a5d233881 Bug#13604121 - LIBMYSQLCIENT.SO MISSING SOME FUNCTIONS PRESENT IN LIBMYSQLCLIENT.A
+get_tty_password  this is the only external symbol in get_password.c,
                   which is explicitly listed in CLIENT_SOURCES
+handle_options    this is in mysys/my_getopt.c
                   adding this sysmbol pulls in the other externals:
T getopt_compare_strings
T getopt_double_limit_value
T getopt_ll_limit_value
T getopt_ull_limit_value

1433621c14 fixes for non-debug builds (CMAKE_BUILD_TYPE=Release or RelWithDebInfo)
client/CMakeLists.txt:
  1. -rdynamic is a linker flag.
  2. it should be used in all builds, not debug only
libmysql/get_password.c:
  prefer a standard function, when possible
  (otherwise a plugin will need to load it from the client)

3c1125d4ca fixes for get_password():
1. on windows: don't hang when there's no console, that is, _getch() returns -1. 
2. on windows: _getch() returns an int, not char.
   to distinguish between (char)255 and (int)-1
3. everywhere. isspace(pos[-1]) == ' ' never worked,
   isspace() returns a boolean, not a char. the never-worked loop was
   removed to preserve the existing behavior.

1f8efaccd4 Bug#13101974 SLAVE CAN'T CONNECT AS REPLICATION USER USING WINDOWS AUTH PLUGIN
Problem was that built-in client-side support for Windows Native Authentication (WNA) was included only in the client library, but not into the server code (which also uses some of the sources from the client library).

This is fixed by modyfying sql/CMakeLists.txt to include the client-side WNA plugin library and enable WNA related code by defining AUTHENTICATION_WIN macro.

Also, the logic of libmysql/CMakeLists.txt is simplified a bit.

a5b881594d MWL#192: Non-blocking client API for libmysqlclient.
All client functions that can block on I/O have alternate _start() and
_cont() versions that do not block but return control back to the
application, which can then issue I/O wait in its own fashion and later
call back into the library to continue the operation.

Works behind the scenes by spawning a co-routine/fiber to run the
blocking operation and suspend it while waiting for I/O. This
co-routine/fiber use is invisible to applications.

For i368/x86_64 on GCC, uses very fast assembler co-routine support. On
Windows uses native Win32 Fibers. Falls back to POSIX ucontext on other
platforms. Assembler routines for more platforms are relatively easy to
add by extending mysys/my_context.c, eg. similar to the Lua lcoco
library.

For testing, mysqltest and mysql_client_test are extended with the
option --non-blocking-api. This causes the programs to use the
non-blocking API for database access. mysql-test-run.pl has a similar
option --non-blocking-api that uses this, as well as additional
testcases.

An example program tests/async_queries.c is included that uses the new
non-blocking API with libevent to show how, in a single-threaded
program, to issue many queries in parallel against a database.

tests/mysql_client_test.c:
  Replace blocking calls with wrappers around the non-blocking calls, used in
  mysql_client_test to test the new non-blocking API.
tests/nonblock-wrappers.h:
  Replace blocking calls with wrappers around the non-blocking calls, used in
  mysql_client_test to test the new non-blocking API.

93f2daf3ad Bug#12897501 REPLICATION DOES NOT SUPPORT WINDOWS AUTH PLUG-IN
Connection of slave to master using a replication account which authenticates
with an external plugin was not possible.

Fixed by making sure that the CLIENT_PLUGIN_AUTH capability is set when client connects using mysql_real_connect(). Also, a plugin-dir path used by client library to locate authentication plugins is set based on the analogous server setting. This is done in connect_to_master() function before a call to mysql_real_connect().

cee822ca79 Bug#12873214 WINDOWS AUTHENTICATION PLUGIN PRODUCES EXCESSIVE RECORDS IN SERVER ERROR LOG
Changed semantics of AUTHENTICATION_WIN_LOG environment variable recognized by client library to accept the following values which are levels of logging done during Windows authentication handshake:
      
  0 - no logging
  1 - log only error messages
  2 - additionally log warnings
  3 - additionally log info notes
  4 - also log debug messages
      
Setting it to 'on', 'yes' or 'true' will request log level 2 and setting it to 'debug' or 'dbug' will request log level 4.

4171483b53 Backport Fix for Bug#24509 - 2048 file descriptor limit on windows needs increasing.
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.

Noteworthy benefit of this patch is that it removes limits from the table_cache size - 
allowing for more simultaneus users

8c6d569f2a Bug#12612143 - LIBMYSQL 5.5.13 BREAKS USER APPLICATION BUILD
Since the Windows authentication support has been added to libmysql, this library depends on the system Secur32 library. Consequently, clients which are linked against libmysql should be also linked with Secur32 (in addition to ws2_32).

In MS VC++ it is possible to embed information about required libraries into object file using #pragma directive. This patch adds such directive when the Windows authentiaction support is compiled. This is similar to analogous #pragma for ws2_32 library in my_init.c

  Extended cast functions Item_func_signed() and Item_func_unsigned() to work with dynamic types
  Added Item_double_typecast()
sql/item_func.h:
  Added class Item_double_typecast()
sql/item_strfunc.cc:
  Added functions for COLUMN_CREATE(), COLUMN_ADD(), COLUMN_GET() and COLUMN_LIST()
sql/item_strfunc.h:
  Added classes for COLUMN_CREATE(), COLUMN_ADD(), COLUMN_GET() and COLUMN_LIST()
sql/item_timefunc.cc:
  Added flag argument to str_to_time_with_warn()
  Updated Item_char_typecast() to handle result type that may change between calls (for dynamic columns)
  Added Item_time_typecast::get_date() to ensure that we cast a datetime to time properly.
sql/item_timefunc.h:
  Added get_date() to Item_time_typecast() to allow proper results for casting time to datetime
sql/lex.h:
  Added new SQL function names
sql/my_decimal.cc:

  Added my_decimal2int()
sql/my_decimal.h:
  Moved some constants to my_decimal_limits.h

  Made my_decimal2int() a function as it's rather long (no reason to have it inline)
  Added decimal2my_decimal() function.
sql/mysql_priv.h:
  Prototypes for new functions
sql/share/errmsg.txt:
  New error messages for wrong casts and dynamic columns

32a41e5a25 Patch for Bug#12374486 - SEVERE MEMORY LEAK IN PREPARED STATEMENTS
THAT CALL STORED PROCEDURES.

The bug was introduced by WL#4435. The problem was that if a stored
procedure generated a few result sets with different set of columns,
a new memory would be allocated after every EXECUTE for every
result set.

The fix is to introduce a new memory root in scope of MYSQL_STMT,
and to store result-set metadata in that memory root.
