[issue27415] regression: BaseEventLoop.create_server does not accept port=None

[Marcus Cobden]

Marcus Cobden added the comment:

Ah thanks, that's fair.
It seems a shame since this regression was introduced to 3.4 by a 
security/bugfix release.
Since there's a workaround it's not a big deal.

Still doesn't work in Python 3.4.5; I can confirm it's fixed in Python 3.5.2.

I should add that port=0 is an acceptable workaround

[issue27415] BaseEventLoop.create_server does not accept port=None

[Marcus Cobden]

New submission from Marcus Cobden:

With the most recent 3.4 bugfix, calling create_server with port=None stopped 
working.
This also affects 3.5, and I would imagine also 3.6, but haven't checked that.

Test case:

import asyncio; l = asyncio.get_event_loop(); 
l.run_until_complete(l.create_server(lambda: None, host='0.0.0.0', port=None))

Expected result: a socket object
Broken result: "TypeError: an integer is required (got type NoneType)"

[issue17558] gdb debugging python frames in optimised interpreters

[Marcus Cobden]

Marcus Cobden added the comment:

Is there anyone who could take a look at this? I'd rather it not bit-rot into 
oblivion.

I know the code quality is rather poor, but I can fix that.

[issue17558] gdb debugging python frames in optimised interpreters

[Marcus Cobden]

New submission from Marcus Cobden:

I've made some tweaks to the libpython.py util functions to better pick up 
python frames when using a normal python interpreter.

It's not by any means perfect, but it works on my ubuntu-shipped python 
interpreter (with debugging symbols installed, but not running the debug 
interpreter).

It works by finding the top frame via the thread state struct, and then going 
up the frame stack, comparing the stack pointer to a stack pointer in the C 
context.

I'd appreciate some feedback/advice :)
