attach(): AttributeError: 'module' object has no attribute 'poll' about pyringe HOT 6 OPEN

It looks like the poll system call exists on OS X, but its implementation is so broken that they disabled it in the select python module. The canonical replacement for select.poll seems to be select.kqueue, but that's BSD-specific and won't work on Linux.

Properly fixing #4 would probably remove our use of select.poll and eliminate this issue altogether.

HI It's work with kqueue. I will try to push changes to master on evening. With this change pyringe works booth on mac os and linux.

As kqueue is BSD-specific and Linux isn't a BSD derivative, kqueue doesn't exist on linux:

>>> import select
>>> select.kqueue
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'kqueue'

I haven't seen the code, but unless you want to lock out Linux users you'd have to supply two alternate implementations of the tempfile-based IPC.
As an alternative, I propose factoring out the approach already seen in payloads/exec_socket.py into something all parts of the debugger can use.
That would fix issue #4, #14, make resolving #2 a lot easier, and would do away with tempfile-based IO.

Did this ever come to a resolution? I'd like to use pyringe on osx.
PS I just this evening received the same bug (no attribute poll)

from pyringe.

It hasn't so far. "Properly" fixing this means rewriting the IPC mechanism used for communicating with gdb, and it's not likely I'll get around to doing that.

The system build of python on os x just doesn't supply the poll interface. The build provided by macports does, however from what people say its semantics are different. So using the macports build of python may let you work around this issue for the time being.

Thanks for the tip. I recompiled my python with --with-poll and I got pyringe to connect.
Thanks for maintaining this repo!
Here's how I did it, for future readers:

brew install python --with-poll

I also had to run

sudo python -m pyringe

to get around the gdb code signing error, although I think there is another way around this.
