random heap corruption using threads about python-magic HOT 8 CLOSED

Hi, sorry for the delayed response. I'm not entirely sure what's going on. It's extremely odd that you see all instances die at once, I can't think of a way that would happen.

One possibility is that somehow magic_close() is being called on self.cookie and then that cookie is re-used. I don't see how that could happen. I did add some defensive checks here:

4142c79

If you use a current version of the wrapper does the problem still occur?

Another option (unlikely) is some bug in file_vprintf. I've traced through the logic there and am somewhat confident it won't double free ms->o.buf, but it's hard to be sure.

Now, I believe the GIL is held during all these calls. If it is not held then that's a whole different problem.

I'm going to optimistically assume that this is resolved, if not please re-open.

from python-magic.

I am facing a similar issue. We are using python-jira library, which depends upon python-magic==0.4.2
Running under Django 1.4.2 Ubuntu 12.04 64 bit - After making a call from jira python, the Django server segfaults.

I too am facing this double free corruption error, I am also using this in a multi-threaded environment. If there is any more information I can provide to help, let me know!

    mime_type = magic.from_file(file_path, mime=True)
    if not mime_type:
        mime_type = 'unknown'

I was experiencing similar issues in a multithreaded environment, I found giving each thread it's own instance of the Magic class fixed it. Something like this:

import collections
import magic
import threading

class magicdict(dict):
    def __missing__(self, flags):
        self[flags] = value = magic.Magic(mime=flags & magic.MAGIC_MIME, mime_encoding=flags & magic.MAGIC_MIME_ENCODING)

        return value

def lets_see_some_magic(flags=magic.MAGIC_NONE, wand_cache=collections.defaultdict(magicdict)):
    return wand_cache[threading.current_thread()][flags]

I'm not convinced this should be handled inside python-magic, but maybe documented as a known work around, or an optional activation, magic.attempt_thread_safety() or so.

Oh wow. I spent some time digging through libmagic looking for the magic_close issue and couldn't find the issue but @thesteed's stack is really helpful. Fix coming.

i see a fix is landed. could you consider releasing a new version to pypi?

For some reason I was under the impression the GIL was held while in extension calls by default, but turns out CDLL does not hold the GIL (PyDLL does). This was a huge oversight on my part, my apologies.

I will push a new version shortly, I'd like to triage all the new issues first.
