I have a problem while calling mysql_close()
After the dtor of Connection() is called, the program hangs somewhere in libmysql after
mysql_close() was called in:
Connection::~Connection()
{
mysql_close(&mysql_);
is_connected_ = false;
}
during debugging i found a potential problem, but it did not fix the problem.(i put some
suggestions at the end of this mail)
In the problem might depend on the fact, that i still have a 'Result' stored somewhere
else , which is not deleted while closing the connection , but i'm not sure (this would
mean, that mysql_close() knows, there is a 'Result' somewhere and waits for closing it
(?)...hard to believe...)
Any ideas what may cause the hanging and for what i should look?
-------------------------------------------------------------------------------
The code change i would suppose is the following:
bool Connection::connect(cchar* db, cchar* host, cchar* user,cchar* passwd, uint port,
my_bool compress,
unsigned int connect_timeout, cchar* socket_name,
unsigned int client_flag)
{
lock();
// Drop previous connection, if any
if (connected())
{
disconnect();
// i added this line, becaus mysql_close deallocates memory
// which was allocated in mysql_init. this is necessary for the
// mysql_real_connect later in this function
mysql_init(&mysql_);
}
...
...
...
// Establish connection
if (mysql_real_connect(&mysql_, host, user, passwd, db, port,
