context: make repo[<filtered binary nodeid>] match node If you pass in a binary nodeid of a filtered node to repo.__getitem__, it would run through this code: try: self._node = changeid self._rev = repo.changelog.rev(changeid) return except error.FilteredLookupError: raise except LookupError: pass However, repo.changelog.rev() would raise a FilteredLookupError, not FilteredRepoLookupError. Instead, we would hit the "except LookupError" and continue, trying to interpret the nodeid as a bookmark etc. The end result would be an error like this: abort: unknown revision 'ddadbd7c40ef8b8ad6d0d01a7a842092fc431798'! After this patch, it would instead be: abort: 00changelog.i@ddadbd7c40ef8b8ad6d0d01a7a842092fc431798: filtered node! This only happens when we get a binary nodeid, which means it's not string directly from the user, so it would be a programming error if it happened. It's therefore a little hard to test (I checked test-context.py, but it doesn't use obsmarkers). It looks like this has been wrong ever since dc25ed84bee8 (changectx: issue a FilteredRepoLookupError when applicable, 2014-10-15). Differential Revision: https://phab.mercurial-scm.org/D3144

context: move handling of filtering error to revsymbol() (API) When changectx's constructor runs into various Filtered*Error, it creates an exception with a hint about using --hidden. This only makes sense when the revision was provided by the user (if we get e.g. a FilteredLookupError from repo[p1], then it's instead a programming error). Thus, I'm moving the handling into revsymbol(). Also changed "unfilteredrepo[changeid]" to "revsymbol(unfilteredrepo, changeid)" as part of the move.

mq: avoid a silly conversion from binary nodeid to hex We generally deal with binary nodeids in code. In this case the hex nodeid was passed to strip.checksubstate() where it was passed to repo.__getitem__, which of course accepts a binary nodeid.

narrow: remove unused "cacheprop" stuff This is unused since D3046. I didn't even notice it then, but tests still pass so I hope it's still handled safely. Differential Revision: https://phab.mercurial-scm.org/D3142
