Threading issue?

[Dave Pawson]

Using python-gnupg on Python3.

Hangs, only cleared with ^c

 File "/usr/lib/python3.5/site-packages/gnupg.py", line 1254, in search_keys

    self._collect_output(p, result, stdin=p.stdin)

  File "/usr/lib/python3.5/site-packages/gnupg.py", line 898, in _collect_output

    dr.join()

  File "/usr/lib64/python3.5/threading.py", line 1054, in join

    self._wait_for_tstate_lock()

  File "/usr/lib64/python3.5/threading.py", line 1070, in _wait_for_tstate_lock

    elif lock.acquire(block, timeout):

KeyboardInterrupt

https://github.com/python/asyncio/issues/312

Seems to relate?

Related code is

encrypted_ascii_data = gpg.encrypt(data,

                                   symmetric=True,

                                   passphrase=secret,

                                   sign=True,

                                   recipients=None) 

data is  a simple string

passphrase obtained from console.

Having locked up, it seems to remain locked. 

Suggestions please.

Dear Dave,

Does it work if you don't pass sign=True? Also, what OS (looks like Linux), what version of GnuPG, what version of python-gnupg, which exact version of Python 3.5?

Regards,

Vinay Sajip

[Dave Pawson]

No - still hangs with sign=False.
on Linux, Fedora 25, 64 bit.

[Vinay Sajip]

Dear Dave,

Sorry, which version of GnuPG and python-gnupg? Can you try the test_gnupg.py which comes with the source distribution and see if that runs OK on your system?

Regards,

Vinay Sajip

How to run the test?

# updatedb
[root@localhost ~]# locate test_gnupg.py
[root@localhost ~]#


Where is test_gnupg.py please?

Dear Dave,

Download the source archive from PyPI and unpack it. You can get it, along with md5 hash and GPG signature, from

https://pypi.python.org/pypi/python-gnupg

N.B. You appear to be logged in as root and are installing packages into system Python locations. This is generally regarded as bad practice. You should be using a venv (virtual environment), unless you have a good reason for doing otherwise.

Why? Is it a newer version?
When do you let Fedora know?

So for every app I set up a new environment? Sounds crazy to me, is there
any good reason to use venv?
I want all my apps available to all users, hence I install as root.
Again, is there any reason not to?

Confused with the reasoning?

Downloaded.

Requirement already satisfied: python-gnupg==0.4.0 from
file:///apps/py/python_gnupg-0.4.0-py2.py3-none-any.whl in
/usr/lib/python3.5/site-packages


So it seems I have the same version as that on pypi

[Vinay Sajip]

Dear Dave,

Please Google for why you should use venvs and not install packages from PyPI into your system site-packages. There should be a distro version of python-gnupg you can use, and can use dnf to install that.

I am unable to reproduce the problem on a fresh Fedora 25 64-bit machine with PyPI's python-gnupg installed into a venv.

I have updated the BitBucket issue.
