Doc Text:
Sphinx builds HTML documentation in FIPS mode properly Previously, the Python Sphinx generator failed to build documentation in the HTML format on systems with FIPS mode activated. With this update,the use of the md5() function has been fixed by setting the "used_for_security" parameter to `false`. As a result, Sphinx now builds HTML documentation as expected.

Description Bohuslav "Slavek" Kabrda 2013-05-24 11:30:03 UTC
Sphinx html builder uses md5 function for determining whether the docs have been already built [1] and thus fails with ValueError in any html docs build. This would IMHO be safe to alter using usedforsecurity=False in md5 function call (because this is really not used for security).

Yes, I think that's a completely valid option (or at least I can't see an attack scenario that would apply to building/not building documentation).

Another option is to migrate to a stronger hash anyway (which would imply a rebuild when upgrading from an older version of sphinx to a newer version of sphinx, but the caching would work fine on the next call of get_outdated_docs() again).

Or just let get_outdated_docs() return everything if md5 computation fails.
