New submission from Vitaly Kruglikov <vitaly.k...@gmail.com>: There doesn't appear to be an ordained mechanism for getting notified when a Transport's (or WriteTransport's) write buffer drains to zero (i.e., all output data has been transferred to socket). I don't want to hijack `set_write_buffer_limits()` for this purpose, because that would preclude me from using it for its intended purpose.
I see that transport in selector_events.py has a private method `_make_empty_waiter()`, which is along the lines of what I need, but it's private and is used by `BaseSelectorEventLoop._sendfile_native()`. Just like `BaseSelectorEventLoop._sendfile_native()`, my app needs equivalent functionality in order to be able to run the loop (`run_until_complete()`) until the transport's write buffer empties out. ---------- components: asyncio messages: 314236 nosy: asvetlov, vitaly.krug, yselivanov priority: normal severity: normal status: open title: No clean way to get notified when a Transport's write buffer empties out type: enhancement versions: Python 3.5, Python 3.6, Python 3.7, Python 3.8 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue33118> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
