running domoticz->Fatal Python error: drop_gil: GIL is not locked

[bassie127]

I compiled domoticz on Arch linux (AUR package https://aur.archlinux.org/packages/domoticz/).
* Building is OK.
* When I start domoticz via: systemctl start domoticz it crashes with "Fatal Python error: drop_gil: GIL is not locked".
* I have searched but cannot find a solution.
All tips appreciated.

Hi,

did you ever get this resolved? I'm currently experiencing the same issue.

Thanks!

Because the error is python related, I decided to downgrade the 2 python packages that were upgraded just before the issue occurred:

• python-setuptools (1:40.4.3-1 -> 1:40.2.0-1)
• python (3.7.0-4 -> 3.6.6-1)

Now I don't get the error anymore.
For me this is an acceptable workaround. I hope a future update of python or domoticz will fix this issue.

I saw some other projects that solved the issue, and they all reference https://vstinner.github.io/python37-gil-change.html. This post also explains why it still works with older versions of Python. (the complete story: https://bugs.python.org/issue20891)

Seems like that Domoticz needs a fix to be able to use the latest Python version. I think that this issue is about the same problem.

Are you building beta or stable?

Python 3.7 support was added in beta and tested in Windows a while ago

Where did you find the downgrade installation? Culdn't find any in repos for Arch (only AUR). Trying to compile it myself now, but run in to some problem with it (hopefully my fix will work).

I had the previous version in my pacman cache: /var/cache/pacman/pkg/
Hope you have them too!
