What are multithreading bugs?
Classification of Concurrency Bugs Concurrency bugs occur when multiple threads, processes, or CPUs interact with each other. Deadlock is where two or more threads are in the waiting status and each thread is waiting for either resources from another thread or a task’s termination.
How do you debug multithreaded?
Debug the multithreaded app
- In the source code editor, look for one of the following code snippets: C# Copy.
- Left-click in the left gutter of the Thread.
- On the Debug menu, select Start Debugging (F5).
- In the source code editor, locate the line that contains the breakpoint.
What are the most common multithreaded bugs in software?
Our biggest problem: multi-threaded concurrency bugs. Most of our class libraries are written to be asynchronous by use of some thread pool classes. Methods on the class libraries often enqueue long running taks onto the thread pool from one thread and then the callback methods of that class get invoked on a different thread.
Is there a way to fix multithreaded bugs?
So now we have a bug in which Shutdown could get called while OnHttpNetworkRequestComplete is occuring on. A tester finds the bug, captures the crash dump, and assigns the bug to a developer. He in turn fixes the bug like this. The above fix looks good until you realize there’s an even more subtle edge case.
Which is a problem in multithreading-producer / consumer problem?
The problem in your scenario, is that the producer writes continuously new items until buffer is full, so there is a risk of letting the consumers starve until buffer is full, thus arriving de facto at a sequentialization of the processing.
Which is better logging or multi threading environment?
Failing that, like Péter Török said, Logging is probably be the way. As far as I know, Debugger did a bad job on multi-threading environment. try to locate where is the lock is, get a whole what resources are waiting, and in what condition the racing condition occurs.
