Switch from pkg_resources to modern packaging support.
Review Request #13146 — Created July 13, 2023 and submitted
pkg_resources
is on its way out, withimportlib.resources
and
importlib.metadata
taking over much of the functionality.This change updates our codebase to use these modern modules (by way of
backport modules depended on by Djblets) instead ofpkg_resources
.
The updates are largely straightforward, with the biggest change being a
migration forreviewboard.wsgi
to remove the import and some old
multi-versioned install setup code originally contributed by Fedora.
Unit tests pass.
Verified that hosting services and SCMTools loaded by entrypoint were
available.Tested upgrading older
reviewboard.wsgi
files.Tested new sites with the updated
reviewboard.wsgi
file.Tested the help output of
rb-site
to verify listed file paths.Tested
rbext create
