minrk / appnope Goto Github PK

I'm getting a deprecation warning in (Windows) CI in a program depending on (macOS-based) appnope:

..\..\Users\appveyor\AppData\Local\pypoetry\Cache\virtualenvs\corrscope-2f2v7ZI7-py3.8\lib\site-packages\appnope\__init__.py:8
  C:\Users\appveyor\AppData\Local\pypoetry\Cache\virtualenvs\corrscope-2f2v7ZI7-py3.8\lib\site-packages\appnope\__init__.py:8: DeprecationWarning: invalid escape sequence \d
    return tuple(int(s) for s in re.findall("\d+", version_s))

In https://github.com/minrk/appnope/blob/main/appnope/__init__.py, did you mean to write r"\d+" rather than "\d+"?

Appnope 0.1.1 import fails. I've installed in virtual env as follows

$ python3 -m venv venv
$ source venv/bin/activate
(venv) $ pip install -U pip

Since almost 2 years i figure out a problem when installing and using jupyter notebooks in a virtual environment on Mac. I always receive the following error when starting a notebook:

ModuleNotFoundError: No module named 'appnope'

I recognised that you already had the issue with appnope 0.1.1 and that going back to 0.1.0 fixed it. Unfortunately for me this problem also appears with appnope 0.1.2 and appnope 0.1.3.

I am currently using Python 3.9.15 on MacOS Venture 13.2. I also had this problem on Python 3.7 and older MacOS versions.

Steps:

1. Add this code in a file:

from multiprocessing import Pool
import appnope

def f(x):
    appnope.nope()

if __name__ == '__main__':
    with Pool(5) as p:
        print(p.map(f, [1]))

2. Run with ipython crash.py
3. Crash with a segfault and prints:

objc[2560]: +[NSString initialize] may have been in progress in another thread when fork() was called.
objc[2560]: +[NSString initialize] may have been in progress in another thread when fork() was called. We cannot safely call it or ignore it in the fork() child process. Crashing instead. Set a breakpoint on objc_initializeAfterForkError to debug.

It would be great if this could also be used to prevent system sleep. All the required infrastructure already seems to be there.

I am importing and calling appnope at the top of my notebook as follows:

However, I am still seeing overnight runs being napped. Running on OS X 10.9.4 and Python 2.7.6. Is there any way of diagnosing why this would be happening?

At least the _nope module works on Python 3 and probably the rest too. But setup.py uses exec which is a function in py3k.

Thanks for this BTW: we've got IEP running on Maverick again :)

Hi!

Could you check the issue please?
(I just found the appnode repository e.g here.)

I recently encountered the IPython AppNap issue probably after upgrading my Mac from Mojave to Catalina. I observe very slow key response (freezes every ~1 sec) in an IPython session after using the ROOT package, which is a huge analysis library for particle physics. The issue was reported here a few days ago because I first thought that it was a ROOT issue.
https://sft.its.cern.ch/jira/browse/ROOT-10860

After discussing the ROOT developers, it was found that my issue was due to AppNap, and calling appnope.nope() in ~/.ipython/profile_default/startup/ipython_init.py resolved it. So, please first let me thank you very much.

What still puzzling me is that this issue does not appear universally. Would you tell me why I need to manually call appnope.nope() in the environments 1 and 2 ? Do you have any idea? If there is a reason, I would like to make a issue report in the Homebrew repo.

Environment 1 (Need appnope)

• macOS 10.15.5
• Homebrew
• IPython 7.15.0 installed via pip3 (Homebrew)
• Python 3.7.6 (Homebrew)
• Not a clean Mac (my main environment)

Environment 2 (Need appnope)

• macOS 10.15.5
• Homebrew
• IPython 7.15.0 installed via pip3 (Homebrew)
• Python 3.7.6 and 3.7.7 (Homebrew)
• Almost clean virtual machine

Environment 3 (OK)

• macOS 10.15.5
• Anaconda3-2020.02-MacOSX-x86_64
• IPython 7.15.0
• Python 3.8.3
• The same machine as env. 1

Environment 4 (OK)

• Mojave 10.14.6
• Homebrew
• IPython 7.4.0 (Homebrew's pip3)
• Python 3.7.6 (Homebrew)
• Not a clean Mac (my previous main machine)

Environment 5 (Need appnope)

• macOS 10.15.5
• IPython 7.15.0 installed via system pip3
• Python 3.7.3 (System default)
• Almost clean virtual machine

Environment 6 (Need appnope)

• macOS 10.15.5
• Python 3.8.3 (official installer)
• IPython 7.15.0 installed via pip3 (official install)
• Almost clean virtual machine

I think you forgot to add this file...
