Summary

This allows

cd tests && python $CREW/tests/run-tests.py -j7 --extra-config-opt devel.all-warnings=no --blacklist=<(ls test*lfs*.t test*fastanno*.t test*treeman*.t) test*remotefilelog*.t

to pass against core revision 623081f2abc2, which is fairly recent. I
think that's the entire subset of remotefilelog functionality that we
need to worry about for Google, but the disabling of the
test*treemanifest*.t tests worries me a little, so I might be back
soon with more fixes.

There's some probably-wrong hacks in here, but it seems to work.

Remotefilelog does not have rev all over the place. See:

def rev(self, node):
    # This is a hack to make TortoiseHG work.
    return node

Maybe raising NotImplementedError is safer, if it's not used.

238

It does not have a return. Does it actually get used somewhere? Maybe raising NotImplementedError is safer to capture surprises?

remotefilelog/shallowbundle.py
48–50

Maybe just make it return True for most cases:

return not repo.ui.configbool('treemanifest', 'treeonly')
140–141

Need removal.

146

I think most of the remaining code is not prepared for an empty linknode (including storage). Maybe special case it so it can be stored as nullid and change remotefilectx.py to ignore nullid linknodes.

It's needed, fortunately by setting _generaldelta=True we end up on a codepath where it's only used as a UUID and not as a sortable.

238

Someone was at least referencing and calling it. I'm a little surprised the missing return (meaning it returned None) didn't break anything, but I've corrected that issue.

remotefilelog/shallowbundle.py
140–141

My debugging secrets revealed!

146

I'm not following - this seems to work and pass tests. I'm not sure how I could fill in the linknodes for a given file log, because remotefilelog has no way of iterating file revisions. Does that impasse make sense?

(Happy to discuss on IRC if you like.)
