POSIX requires that a signal handler defined with sigaction()
is not reset on delivering a signal unless SA_NODEFER or
SA_RESETHAND is set. It is therefore unnecessary to redefine
the handler on signal delivery on platforms where sigaction()
is used without those flags.
include/my_alarm.h:
Renamed DONT_REMEMBER_SIGNAL ->
SIGNAL_HANDLER_RESET_ON_DELIVERY.

automatic reconnect
A client with automatic reconnect enabled will see the error
message "Lost connection to MySQL server during query" if the
connection is lost between mysql_stmt_prepare() and
mysql_stmt_execute(). The mysql_stmt_errno() number, however,
is 0 -- not the corresponding value 2013.
This patch checks for the case where the prepared statement
has been pruned due to a connection loss (i.e., stmt->mysql
has been set to NULL) during a call to cli_advanced_command(),
and avoids changing the last_errno to the result of the last
reconnect attempt.
Apart strict-aliasing warnings, fix the remaining warnings
generated by GCC 4.4.4 -Wall and -Wextra flags.
One major source of warnings was the in-house function my_bcmp
which (unconventionally) took pointers to unsigned characters
as the byte sequences to be compared. Since my_bcmp and bcmp
are deprecated functions whose only difference with memcmp is
the return value, every use of the function is replaced with
memcmp as the special return value wasn't actually being used
by any caller.
There were also various other warnings, mostly due to type
mismatches, missing return values, missing prototypes, dead
code (unreachable) and ignored return values.
BUILD/SETUP.sh:
Remove flags that are implied by -Wall and -Wextra.
Do not warn about unused parameters in C++.
BUILD/check-cpu:
Print only the compiler version instead of verbose banner.
Although the option is gcc specific, the check was only
being used for GCC specific checks anyway.
client/mysql.cc:
bcmp is no longer defined.

SIGSEGV.
This patch reinstates the reloading of character set data when
a mysql_library_init() is done after a mysql_library_end().

The problem is a somewhat common misusage of the strmake function.
The strmake(dst, src, len) function writes at most /len/ bytes to
the string pointed to by src, not including the trailing null byte.
Hence, if /len/ is the exact length of the destination buffer, a
one byte buffer overflow can occur if the length of the source
string is equal to or greater than /len/.
client/mysqldump.c:
Make room for the trailing null byte.

As documented in the bug report, the double checked locking
pattern has inherent issues, and cannot guarantee correct
initialization.
This patch replaces the logic in init_available_charsets()
with the use of pthread_once(3). A wrapper function,
my_pthread_once(), is introduced and is used in lieu of direct
calls to init_available_charsets(). Related defines
MY_PTHREAD_ONCE_* are also introduced.
For the Windows platform, the implementation in lp:sysbench is
ported. For single-thread use, a simple define calls the
function and sets the pthread_once control variable.
Charset initialization is modified to use my_pthread_once().
include/my_no_pthread.h:
Dummy my_pthread_once() for single thread use.
include/my_pthread.h:
Declaration for new function my_pthread_once().
mysys/charset.c:
Logic in init_available_charsets() is simplified.
Using my_pthread_once() for all calls to this func.
mysys/my_winthread.c:
Windows implementation of my_pthread_once().
Don't use static link by default (in compile-pentium) as some new systems doesn't have all static libraries available
Change type for functions in plugin.h:str_mysql_ftparser_param() to const unsigned char and string lengths to size_t.
One effect of the above change is that one needs to include mysql_global.h or define size_t before including plugin.h
This fixes a case where mysql_client_test failed with newer gcc that enables strict-aliasing by default

Restore a stub of the removed mysql_odbc_escape_string function
to fix a ABI breakage. The function was intended to be private
and used only by Connector/ODBC, but, unfortunately, it was exported

original function is inherently broken and shouldn't be used.
This restoration only applies to MySQL 5.0. This will be addressed

This patch fixes a number of GCC warnings about variables used
before initialized. A new macro UNINIT_VAR() is introduced for
use in the variable declaration, and LINT_INIT() usage will be
gradually deprecated. (A workaround is used for g++, pending a
patch for a g++ bug.)
GCC warnings for unused results (attribute warn_unused_result)
for a number of system calls (present at least in later
Ubuntus, where the usual void cast trick doesn't work) are
also fixed.
client/mysqlmanager-pwgen.c:
A fix for warn_unused_result, adding fallback to use of
srand()/rand() if /dev/random cannot be used. Also actually
adds calls to rand() in the second branch so that it actually
creates a random password.
- Remove bothersome warning messages. This change focuses on the warnings

Various parts of code used different 'precision' arguments for sprintf("%g") when converting
floating point numbers to a string. This led to differences in results in some cases
depending on whether the text-based or prepared statements protocol is used for a query.
Fixed by changing arguments to sprintf("%g") to always be 15 (DBL_DIG) so that results are
consistent regardless of the protocol.
This patch will be null-merged to 6.0 as the problem does not exists there (fixed by the
patch for WL#2934).
client/sql_string.cc:
Use 15 (DBL_DIG) as a precision argument for sprintf(), as Field_double::val_str() does.
libmysql/libmysql.c:
Use 15 (DBL_DIG) as a precision argument for sprintf(), as Field_double::val_str() does.

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

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()
PREPARE", review fixes:
- make the patch follow the specification of WL#4166 and remove
the new error that was originally introduced.
Now the client never gets an error from reprepare, unless it failed.
I.e. even if the statement at hand returns a completely different
result set, this is not considered a server error.
The C API library, that can not handle this situation, was modified to
return a client error.
Added additional test coverage.
include/errmsg.h:
Add a new client side error: now when we automatically
reprepare a statement, the new result set may contain a different
number of columns.
include/mysql_com.h:
Add a new server status to be sent to the client if the
number of columns in the result set is different.
libmysql/errmsg.c:
Add a new error message.
libmysql/libmysql.c:
Make the client library robust against a result set that
contains a different number of columns from prepare time.
Previously that could never happen, and we simply had an assert.
That means in particular that all clients are advised to upgrade
with transition to 5.1, if they are using prepared statements C API.
Make mysql_stmt_store_result() and mysql_stmt_execute() robust against
"broken" statement handles (those that have an error).
sql/sql_parse.cc:
Clear transient server status flags at start of statement more
systematically.
sql/share/errmsg.txt:
Remove an error that is unused and is not part of any public release.
sql/sql_prepare.cc:
Instead of returning an error in case the number of result set columns
has changed, simply update the client in server status.
That will allow modern clients automatically recover from an error.
tests/mysql_client_test.c:
Add additional coverage to the cases when the number of result
set columns changed as a result of reprepare.
Cover conversion and truncation of result set columns.
