From 2b5941df74806d344c59ec0ca126b81cc7bbffe1 Mon Sep 17 00:00:00 2001 From: Max Romanov Date: Tue, 8 Feb 2022 12:04:41 +0300 Subject: Python: fixing incorrect function object dereference. The __call__ method can be native and not be a PyFunction type. A type check is thus required before accessing op_code and other fields. Reproduced on Ubuntu 21.04, Python 3.9.4 and Falcon framework: here, the App.__call__ method is compiled with Cython, so accessing op_code->co_flags is invalid; accidentally, the COROUTINE bit is set which forces the Python module into the ASGI mode. The workaround is explicit protocol specification. Note: it is impossible to specify the legacy mode for ASGI. --- docs/changes.xml | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'docs/changes.xml') diff --git a/docs/changes.xml b/docs/changes.xml index 64a35da8..a6b1178d 100644 --- a/docs/changes.xml +++ b/docs/changes.xml @@ -43,6 +43,13 @@ some Spring Boot applications failed to start, notably with Grails. + + +incorrect Python protocol auto detection (ASGI or WSGI) for native callable +object, notably with Falcon. + + + -- cgit
