multi-thread environment???

[ghost]

The only thing I found really annoying is the amount of times that PAMAC locks with lock_file since pylamp also has its own lock. I propose to change its blockade by a multi-thread environment where threads lock in the daemon when some client access to danger zones.
This will give you the ease of graphical interface completely separate business, giving greater flexibility to the application.
In a multithreaded enviroment, the thread started by client notifies the thread that is waiting for data (possibly confirmation of a transition).

def EmitTransactionConfirmation(self, info_config):
        self.emit("EmitTransactionConfirmation", info_config)
        self.client_response = False
        self.client_condition.acquire()
        while not self._client_confirm_trans():
            self.client_condition.wait()
        self.client_condition.release()


def Release(self):
        try:
            if not self.client_response:
                self.client_condition.acquire()
                self.client_condition.notify()
                self.client_response = True
                self.client_condition.release()
            self.t.release()
            self.lock_trans.release()
        except:
            pass


def Commit(self):
        if not self.client_response:
            self.client_condition.acquire()
            self.client_condition.notify()
            self.client_response = True
            self.client_condition.release()
        error = ''

 def prepare_transaction_install(self, pkgs, cascade = True, recurse = False):
        self.lock_trans.acquire()
        self.to_add = set()
        self.to_update = set()
        self.to_load = set()
        self.to_remove = set()

I'm forcing to do that, because i have 3 modules that use the same interface, but i recommend do some thing similar...

Yes, this is a bug we are facing a longer time now. Can you patch pamac to use the proper way and the lock from pyalpm? We will include it right away.

I currently make this for my application, but in my application only use a subset of pamac... Clear will be more complex for pamac. When i can test that all is working, i will try to add this to pamac, but i think will be better have this in a non master branch for some time, to be tested first... Have dependency of a daemon with multithread, could create several test cases...
