New submission from Xiang Zhang: BaseHTTPRequestHandler in http.server supports HTTP/0.9. But the response for HTTP/0.9 request is implemented wrong.
Response of HTTP/0.9 request returns message body directly without status line and headers. But if you inherit BaseHTTPRequestHandler and set the default_request_version to "HTTP/1.x", then self.request_version can never be "HTTP/0.9" since in the https://hg.python.org/cpython/file/tip/Lib/http/server.py#l315 branch it does not set version to "HTTP/0.9" and then always sends the status line and headers back. A trivial patch can fix this problem that set version to "HTTP/0.9" in the branch. But this will cause some failure in tests. The tests in test_httpservers use http.client.HTTPConnection to send and receive HTTP message. But since 3.4, HTTPConnection doesn't support HTTP/0.9-style simple responses. We can use it to test HTTP/0.9 connection if the server is implemented in the right way. And since http.client.HTTPConnection has dropped the support for HTTP/0.9, is it reasonable to drop the support in http.server too? ---------- components: Library (Lib) messages: 261898 nosy: xiang.zhang priority: normal severity: normal status: open title: Bad BaseHTTPRequestHandler response when using HTTP/0.9 versions: Python 3.6 _______________________________________ Python tracker <rep...@bugs.python.org> <http://bugs.python.org/issue26578> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
