This will help make failures in the event of a non-negative return code more obvious when they go unhandled; the current behavior in _post_shutdown() is to print a warning message only in the event of signal-based terminations (for negative return codes). (Note: In Python, catching BaseException instead of Exception catches a broader array of Exception events, including SystemExit and KeyboardInterrupt. We do not want to "wrap" such exceptions as a VMLaunchFailure, because that will 'downgrade' the exception from a BaseException to a regular Exception. We do, however, want to perform cleanup in either case, so catch on the broadest scope and wrap-and-re-raise only in the more targeted scope.)

The new library delays this to the accept() call, because binding occurs inside of the call to start_[unix_]server(), which is an async method -- so it cannot happen during __init__ anymore. Python 3.7+ adds the ability to create the server (and thus the bind() call) and begin the active listening in separate steps, but we don't have that functionality in 3.6, our current minimum. Therefore ... Add a temporary workaround that allows the synchronous version of the client to bind the socket in advance, guaranteeing that there will be a UNIX socket in the filesystem ready for the QEMU client to connect to without a race condition. (Yes, it's a bit ugly. Fixing it more nicely will have to wait until our minimum Python version is 3.7+.)

Sorry, no. The VM runs, and it produces output to stdout, and then it goes away again. The test cases and test harnesses *must* output to standard output any information that might be useful for diagnosing problems.

I need to change the interface in the async library entirely to make the process more granular -- We don't need the granularity in a truly async mode, but the sync wrapper that allows the existing iotests corpus to use the library in a synchronous manner *requires* a more granular connection API, so I have to write one. It's in progress, it just might be a few more days; verifying and testing the error pathways has been slow work. (In detail: python's asyncio.create_unix_server() call combines bind() + listen() + accept() into a single discrete step. A synchronous client, though, needs to have a reprieve from all of those blocking steps to launch the QEMU process after listen() but before accept() so it can launch the QEMU process. I was able to pull the bind() step out, but the async listen() + accept() steps the way I initially wrote it are inseparable. Live and learn.) In the meantime, there *IS* a way to use the old library, but I don't think the environment variable in question is routed down into the VM tests. I can look at (as a very quick fix) amending the VM launcher to pass along that environment variable if it sees it set in the host environment -- that should get you on the old, tried-and-true library when you want it, and the test should pass. --js ^ permalink raw reply [flat|nested] 16+ messages in thread
