Dear Maintainer,

I'm an occasional volunteer contributor with the Reproducible Builds[1]
project, and noticed recently that the python-x2go-doc package failed[2] an
automated reproducibility test on Debian.

From investigation, it seems that most if not all of the cause of
non-reproducibility during the test was due to the Sphinx autodoc extension
evaluating some of the default Python method values (like sessions_rootdir[3])
at build-time and including the evaluated value, which varied, in the
documentation.

Because the value of the parameter is determined at _runtime_ (because Python
code is not compiled), this does _not_ indicate any baked-in problem with the
python3-x2go package -- but it does create a reproducibility problem for the
python-x2go-doc package.

As a workaround, we can enable the 'autodoc_preserve_defaults'[4] configuration
setting, meaning that Sphinx will render the method signature defaults using the
original source code as-written, instead of evaluating the corresponding
values.

I'll offer a merge request on Salsa to make that change, and will link that to
this bugreport.

Thanks,
James

The patch mentioned above fixed only parts of the issue. Package
python-x2go-doc still builds not reproducible.

Looking into it now.
