[issue8112] xmlrpc.server: ServerHTMLDoc.docroutine uses (since 3.0) depricated function "inspect.getargspec()"
New submission from tormen : This throws an exception and crashes your DocXMLRPCServer when using registered python functions that use function annotations. Seems inconsistent to me.

[issue8112] xmlrpc.server: ServerHTMLDoc.docroutine uses (since 3.0) deprecated function "inspect.getargspec()"
tormen added the comment:
Okey ...
Consider you have a function:
def fn( str:str ): pass
That you register to your DocXMLRPCServer:
register_function of SimpleXMLRPCDispatcher stores the function object in the
dictionary self.funcs under the name of the function (as key).
Then you start your server and access (with a browser) the ip and port of the
machine running your xmlrpc server which calls
> DocXMLRPCRequestHandler.do_GET which
> generate_html_documenation() which copies the funcs dictionary into methods
> and hands it to
> ServerHTMLDoc.docserver which calls for each function name + function object:
> ServerHTMLDoc.docroutine which calls (for inspect.ismethod and
> inspect.isfunction):
inspect.getargspec on the function object
which will fail if you register an annotated function (like the above "fn") in
the first place:
=
File "/usr/lib/python3.1/inspect.py", line 789, in getargspec
raise ValueError("Function has keyword-only arguments or annotations"
ValueError: Function has keyword-only arguments or annotations, use
getfullargspec() API which can support them
=
Which most probably leads to the conclusion that you should just use the
getfullargspec instead of getargspec just to avoid that the XMLRPC server
crashes if someone registers a annotated function.

tormen added the comment: If you want an example: pydoc3.1 xmlrpc.server 2nd usage pattern change "SimpleXMLRPCServer" to "DocXMLRPCServer" change function signature from "pow(self, x, y)" to "pow(self, x:int, y:int)" and your good to go and have your doc xmlrpc server crashed the moment you send a get request to him (e.g. by accessing "http://ip:port"; in the browser of your choice). -- ___ Python tracker <http://bugs.python.org/issue8112> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue5099] subprocess.POpen.__del__() AttributeError (os module == None!)
tormen added the comment: I ran into the same problem today :( The patch resolved it :) BUT: Could anyone comment on when this patch will or will not live?! ... As the bug is fairly old and already has duplicates and everyone seems to agree on the issue. ... Plus it seems easy enough to edit the patch to include the try: / finally: and to incorporate the remove_stderr_debug_decorations() suggestion. -- nosy: +tormen ___ Python tracker <http://bugs.python.org/issue5099> ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
