* python/qmp: switch qmp-shell to AQMPJohn Snow2022-01-211-0/+3
| | | | | | | | We have a replacement for async QMP, but it doesn't have feature parity yet. For now, then, port the old tool onto the new backend. Signed-off-by: John Snow <jsnow@redhat.com> Reviewed-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com>

* python/aqmp: add __del__ method to legacy interfaceJohn Snow2022-01-211-0/+18
| | | | | | | | | | | | | | | | | | | | | | | asyncio can complain *very* loudly if you forget to back out of things gracefully before the garbage collector starts destroying objects that contain live references to asyncio Tasks. The usual fix is just to remember to call aqmp.disconnect(), but for the sake of the legacy wrapper and quick, one-off scripts where a graceful shutdown is not necessarily of paramount imporance, add a courtesy cleanup that will trigger prior to seeing screenfuls of confusing asyncio tracebacks. Note that we can't *always* save you from yourself; depending on when the GC runs, you might just seriously be out of luck. The best we can do in this case is to gently remind you to clean up after yourself. (Still much better than multiple pages of incomprehensible python warnings for the crime of forgetting to put your toys away.)

* python/aqmp: use absolute import statementJohn Snow2022-01-101-1/+2
| | | | | | | | | | | | | | | pylint's dependency astroid appears to have bugs in 2.9.1 and 2.9.2 (Dec 31 and Jan 3) that appear to erroneously expect the qemu namespace to have an __init__.py file. astroid 2.9.3 (Jan 9) avoids that problem, but appears to not understand a relative import within a namespace package. Update the relative import - it was worth changing anyway, because these packages will eventually be packaged and distributed separately.

* python/aqmp: Fix disconnect during capabilities negotiationJohn Snow2021-11-161-5/+13
| | | | | | | | | | | | | | | | | | | | | | | If we receive ConnectionResetError (ECONNRESET) while attempting to perform capabilities negotiation -- prior to the establishment of the async reader/writer tasks -- the disconnect function is not aware that we are in an error pathway. As a result, when attempting to close the StreamWriter, we'll see the same ConnectionResetError that caused us to initiate a disconnect in the first place, which will cause the disconnect task itself to fail, which emits a CRITICAL logging event. I still don't know if there's a smarter way to check to see if an exception received at this point is "the same" exception as the one that caused the initial disconnect, but for now the problem can be avoided by improving the error pathway detection in the exit path.

* python/aqmp: Disable logging messages by defaultJohn Snow2021-10-121-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | AQMP is a library, and ideally it should not print error diagnostics unless a user opts into seeing them. By default, Python will print all WARNING, ERROR or CRITICAL messages to screen if no logging configuration has been created by a client application. In AQMP's case, ERROR logging statements are used to report additional detail about runtime failures that will also eventually be reported to the client library via an Exception, so these messages should not be rendered by default. (Why bother to have them at all, then? In async contexts, there may be multiple Exceptions and we are only able to report one of them back to the client application. It is not reasonably easy to predict ahead of time if one or more of these Exceptions will be squelched. Therefore, it's useful to log intermediate failures to help make sense of the ultimate, resulting failure.) Add a NullHandler that will suppress these messages until a client application opts into logging via logging.basicConfig or similar. Note that upon calling basicConfig(), this handler will *not* suppress these messages from being displayed by the client's configuration.

* python/aqmp: add send_fd_scmJohn Snow2021-10-121-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add an implementation for send_fd_scm to the async QMP implementation. Like socket_scm_helper mentions, a non-empty payload is required for QEMU to process the ancillary data. A space is most useful because it does not disturb the parsing of subsequent JSON objects. A note on "voiding the warranty": Python 3.11 removes support for calling sendmsg directly from a transport's socket. There is no other interface for doing this, our use case is, I suspect, "quite unique". As far as I can tell, this is safe to do -- send_fd_scm is a synchronous function and we can be guaranteed that the async coroutines will *not* be running when it is invoked. In testing, it works correctly. I investigated quite thoroughly the possibility of creating my own asyncio Transport (The class that ultimately manages the raw socket object) so that I could manage the socket myself, but this is so wildly invasive and unportable I scrapped the idea. It would involve a lot of copy-pasting of various python utilities and classes just to re-create the same infrastructure, and for extremely little benefit. Nah.
