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


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

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

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?

No such file?

so it is not with the installation.

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

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.

Regards,

Vinay Sajip
