Martin Panter added the comment: Thankyou Eryksun for the detailed explanation. Unfortunately, that means that uploading an unseekable file via urllib.request, or via http.client, isn’t going to work by default on Windows. I see a couple of workarounds with the current code:
* Users can force chunked encoding (manually pass Transfer-Encoding: chunked, and/or encode_chunked=True, depending on the API) * Users can pass an iterator that reads the file: iter(partial(file.read, CHUNK_SIZE), b"") But I never liked how so much behaviour depends on specific details of the upload body object anyway. Perhaps this is an opportunity to change the behaviour so that a file object always triggers chunked encoding. We could add a note to <https://docs.python.org/3.6/whatsnew/3.6.html#changes-in-the-python-api> to warn that uploading files to HTTP 1.0 servers will now require Content-Length to be manually specified. ---------- _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue12319> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
