            fwrite() writes the amount that i'm expecting but not the data that i want
            Asked 2021-Jun-14 at 04:42

            My task is to copy JPEGs from a file the intend here is to find the JPEGs and create a new file to put it, all JPEGs are store back to back and the "identifier" is always in the beggining of a 512 BYTE block. my problem shows only in the first file where it writes 128 bytes before the expected data from the buffer rendering the new file useless.

            what i have tried:

            • Check the original file to see if the data came from it but it does not.
            • Malloc all the pointers to have "clear memory".
            • Reorganize the code.

            any ideas?

            Take a look at the error message. strcpy takes two char * arguments, but in strcpy(values[i].id,field), values[i].id is int.

            When are python imports loaded in memory?
            Asked 2021-Jun-10 at 08:24

            From earlier questions on SO like this and this, it seems that the simple import keyword does not do lazy loading of modules. However, when I run a simple test to check the memory usage before and after the import statement - it seems that some modules are indeed loaded lazily.

            Example:

            ...

            it seems that the simple import keyword does not do lazy loading of modules.

            How should it? import has to guarantee the code in the imported file / module's __init__.py is executed at the point of importing.

            Just try the following: make a file test.py, containing nothing but print("hey!"), and in the same directory, import .test. You'll notice that import really isn't different from just executing the code in test.py.

            I am trying to understand when does a module actually get loaded in memory?

            import name really just executes the specified code in the current namespace under the name namespace. If you define a class in that code, then its instantly visible, has to get parsed, and whatnot.

            And why does an import django command not load all of django modules in memory?

            Because the code that gets executed on import django simply doesn't do that. (just as it doesn't get up and make us the much-deserved coffee!)

            2048 bytes exceed in size the typical MTU (note that TCP is laid over IP, which itself is packet oriented), so data is likely sent via multiple packets. As you have only one single call to recv chances are that you fetch the contents of first packet from the receive buffer before the the TCP/IP stack could place the contents of the follow up packets there.

            Rather have multiple reads in a loop and exit the loop on receiving 0 bytes (remote socket closed):

            problem with client server unix domain stream sockets (servered is able to be accessed by multiple clients)
            Asked 2021-May-30 at 16:19

            as mention above i am trying to make a server and client program. the client should send the length of the sequence of int and the sequence to the server. from the server it will receive the average if it is greater than 10 and a confirmation message else it will receive a failure message. The server creates threads and in the function executed by the threads it does what the client wants plus it keeps count of the successful as well as the total sequences which he receives . I have tried what follows and after i insert the array elements it does nothing and i am not sure why(as you may have guessed i am new to sockets)

            Answered 2021-May-30 at 16:19

            Server sends a variable length string (confirmation) but we need a fixed length message because client can't know beforehand the length to read. Better to just send an int that is 0=fail, 1=success.

            Server sends average first but client reads success/fail message first (i.e. a mismatch in the order of send/recv for these.

            Method to terminate client connection in server is broken. Better to have client send an explicit stop message (and server has to check connection).

            The server doesn't do pthread_join so it can overrun the thread ID array. I changed that to a linked list of a [new] per-task struct. But, I couldn't get the join code to work. Still, it should give you some idea of how to control threads in the general case, even though it's broken somewhat.

            There are many other issues, too numerous to mention individually, but, the code below is refactored and [most of] the bugs are annotated. It's still a bit fragile in places (e.g. server can get "Broken pipe") but the basic communication now works.

            You should pass the download button as a constructor dependency and wrap it in a weak reference as you've done with context.

            I think it may have thrown a ClassCastException because you attempted to force cast it from doInBackground() and the download button from the host of your AsyncTask was a weak reference of the view.

            Minor modification to your existing code should work fine:
