Source: sphinx Followup-For: Bug #998059 X-Debbugs-Cc: debian-python@lists.debian.org
(context: cross-posting based on an idea[1] that has been discussed upstream in sphinx's GitHub repository about how to resolve locale-based build variance) The SPHINXOPTS[2] environment variable provides a way to selectively override defined environment variables (such as LANGUAGE) in a way that should only affect sphinx (limiting the effects on unrelated build steps). For example: SPHINXOPTS='-D LANGUAGE="en_US.UTF-8"' That would allow the objects.inv file to be built in a fixed language on a per-package basis. It doesn't seem ideal to artificially limit documentation localization for affected packages, but could allow many of the affected packages to pass diffoscope reproducibility testing. Alternatives explored: I wasn't able to identify a straightforward, supported way to disable creation of the objects.inv file, nor is it currently possible to invoke a multi-locale HTML sphinx build (an approach that might permit output of monolithic documentation outputs that wouldn't vary based on build environment locale). I'll file a feature request for the former; the latter is tracked by an existing request[3].
