            Bug ID: 58556
           Summary: winhttp web socket api is not thread safe
           Product: Wine
           Version: 10.12
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: winhttp
          Assignee: wine-bugs(a)winehq.org
          Reporter: linuxFTW49(a)gmail.com
      Distribution: ---

WinHttpWebSocketSend and WinHttpWebSocketReceive cannot be called from two
different threads. `socket_receive` can end up calling `send_frame` which is
not thread safe when calling `socket_send` from another thread.
> From the description on msdn
> (https://learn.microsoft.com/en-us/windows/win32/winhttp/concurrency-in-winht...)
> The send and receive sides of a web socket are separate and may be used concurrently; an application may do a send-only operation on one thread at the same time that another thread is performing a receive-only operation.

This is a mismatch in behavior from the windows implementation of winhttp.dll

Do you have an application that depends on this (or more ideally, a simplified
test case with source available)?
