So I finally got around to playing with this set. One thing I found is
that some of the references that were being caught before were not
now... after far too much time, I figured out that the problem was
references to .txt files, of which we have quite a few in the docs.
admin-guide/kernel-parameters.txt in particular is quite popular.
Before this change, those were being turned into xrefs, afterward not.
To address that, I applied this little tweak:
-RE_doc = re.compile(r'(\bDocumentation/)?((\.\./)*[\w\-/]+)\.rst')
+RE_doc = re.compile(r'(\bDocumentation/)?((\.\./)*[\w\-/]+)\.(rst|txt)')
That seems to make things work properly again.
While tracking this down I put in a print for failing cross references,
and noted that we have quite a few; it's a useful way to see where the
stale references are. Maybe I'll try to hack together something to make
those stand out so we can fix them.
Thanks,
jon
