Cannot disable loguru in cython build

[senysenyseny16]

Hi,

I'm using Cython and loguru works but I can't manage (disable) logging:

from loguru import logger

logger.disable(<module_name>)

the above code works for source distribution and doesn't work with the binary (Cythonized) distribution.

Has anyone experienced this behavior?

Hi @senysenyseny16.

Cython removes the stack frames, causing Loguru to access the wrong context when a message is logged. Therefore, the logged message is associated with an incorrect module name, and disable() cannot filter it properly.

I'm not aware of any possible workaround, unfortunately. :/

hi @Delgan.

Thanks for your reply 🥲

Note that Cython compatibility with Loguru was improved by #1240.

Using logger.disable(None) should disable logs coming from Cython modules.

The logger.disable() method takes as input the name of the logger to disable (usually a string). Here, None is used because the logger within Cython modules has no name (due to the absence of available stack frame).
