            C++ : undetectable change of variable, artificial "volatile" mutex not works
            Asked 2020-Feb-17 at 15:06

            How it is possible, that is such a line just after if statement with unequal, variables are already equal in pull() method? I have already added Mutex variable, but it not helped.



            Answered 2020-Feb-16 at 11:19

            first, you'd better use std::atomic and/or std::mutex for synchronization purposes. At least use std::flag. volatile has issues in general - it isn't suited for atomic operations - it has a different purpose altogether.

            Second in your code, there is a bug and I don't know to solve it properly with volatile.

            Can't get mysql results more than once
            Asked 2019-Dec-26 at 22:34

            I'm trying so hard to get my socket server python script to loop every so often to check for updates in a mysql table.

            The code works on the first time no problem. on the second loop and every loop after it throws errors.
            Things i've tried:

            • try/catch (for multiple loops to see if ANY work)

            • threading

            • conn.close()

            • cursor.close() (not cursor.commit() any changes so this through errors of course)

            However, I can put the code in a stand alone file and spam running the file and it works perfectly. It doesn't seem to like running the sql code in the same process or file (which i thought threading fixed but i guess i was wrong?)

            Here is the error: (note the first line is the output i'm trying to print in a loop for testing)

            As indicated by the exception, there are unread rows associated with your cursor. To solve this, you have two solutions :

            • Use a buffered cursor, replacing your code with conn.cursor(buffered=True)
            • Or, retrieve every result associated to your cursor using a for loop with something like : for row in cursor: dosomething(row)

            How To Fix Indy TIdTCPServer Freezing When Sending Text To TIdTCPClient?
            Asked 2019-Feb-22 at 08:40

            Cannot send text from TIdTCPServer To TIdTCPClient, the server hanging (Not Responding), it just freezes when trying to send text to the client.

            I Started Recently using Indy TIdTCPClient and TIdTCPServer, i have the client application working well when sending and receiving response from the server form, then issue is from the server it doesn't send data, and when i try to send data like Indy creators provided in their Doc, it just freezes and then stops responding (crashes) :(, the weird thing is that the server sends back the response on Execute Event, and not sending data with my send function, so here is my code that i use:

            Server Execute Event:

            TIdTCPServer is a multi-threaded component, which you are not accounting for propery.

            The server's various events are fired in the context of internal worker threads, not in the context the main UI thread. Your OnExecute code is not syncing with the main UI thread when accessing MessageDisplay1, which can cause all kinds of problems, including but not limited to deadlocks. You MUST sync with the main UI thread, such as with TThread::Synchronize() or TThread::Queue(). For example:

            firemonkey idTcp and Record
            Asked 2018-Nov-25 at 18:38

            Good afternoon.

            The client sends a message to the server, and the server responds by sending two messages to the client.

            The client sees these messages, but the memo records the very first value sent by the server.

            Prompt in what the reason

            Server ----------------------------------------------------



            Answered 2018-Nov-25 at 18:38

            On the server side, your are ignoring the client's request, and flooding the connection with endless responses. The TIdTCPServer.OnExecute event is called in a continuous loop for the lifetime of the connection, not when the client sends a request.

            On the client side, you are running a continuous reading loop in a thread, trying to take in all of those responses. But your use of TThread.Sleep() ensures that loop reads messages much slower than the server can produce them, congesting network traffic.

            But worse, you are hindering your client's ability to process server messages. Your UI timer runs at 100ms intervals, while the reading thread runs at 10ms intervals. So at most, 10 messages may be pushed into the queue per timer interval. Your OnTimer event handler pops only 1 message per interval, leaving up to 9 messages in the queue. So very quickly (~1s), the queue will fill up to its max capacity of 100 messages, and PushItem() will start ignoring messages. You are not checking for push errors/timeouts at all.

            In addition, I see other issues with your code.

            On the server side, you are leaking your TIdTCPServer object, as you don't assign an Owner to it, and you don't Free it. But also, your Form's OnCreate event handler is adding 2 separate bindings to TIdTCPServer - one on and the other on It should be adding only one binding - on

            On the client side, when creating your thread, you should not be calling TIdTCPClient.Connect() or TIdIOHandler.Write() in the thread's constructor, they belong in the thread's Execute() method only.

            And lastly, I would suggest using TQueue instead of TThreadedQueue. The latter uses its own internal threads to manage push/pop timeouts, which is wasted overhead in this situation. You can use TMonitor or TEvent to accomplish the same thing without the extra threads.

            With that said, try something more like this instead:

            I wasn't able to solve this in a proper way. It seems that because you get values when you actually start your session, numpy will complain. I was able to solve the problem by replacing:

            Gracefully terminating all the threads

            I am using this in one of my solution

            My requirement is to clear the queue and kill all the threads gracefully when Stop button is clicked.

            For this I created an ObjectList



            Answered 2017-Nov-22 at 08:03

            Terminate only sets the Terminated property to true. It's important that the internal loop of the thread checks the Terminated property periodically, and returns from the Execute method when it is set to true. After that, use WaitFor in the main thread to check the threads have all ended before you free queue or thread-pool objects.
