[Webkit-unassigned] [Bug 167876] [Soup] Deadlock in NetworkProcess

--- Comment #1 from Carlos Garcia Campos <cgarcia at igalia.com> ---
WebKitSoupRequestInputStream uses a read lock.What is happening is that webkitSoupRequestInputStreamAddData takes the lock, and it calls webkitSoupRequestInputStreamPendingReadAsyncComplete with the lock help. That causes webkitSoupRequestInputStreamReadAsync to be called again to read the next chunk, but in the same run loop operation. webkitSoupRequestInputStreamReadAsync also takes the read lock. I don't know why we are using that read lock, I don't think it's needed, at least now everything should happen in the main thread. But I'm going to look at it in more detail. If the lock is needed, then the solution is to release it before calling webkitSoupRequestInputStreamPendingReadAsyncComplete
