context: stop catching RepoLookupError from namespace.singlenode() As pointed out by Yuya, the RepoLookupError was there for catching errors from repo.branchtip(). However, since 885c0290f7d5 (localrepo: add ignoremissing parameter to branchtip, 2014-10-16), that should no longer happen. I think it should now be an error if a namespace raises a RepoLookupError, so we propagate the exception up and and make it easy to fix, rather than trying to interpret the changeid as nodeid prefix and raise a general "unknown revision '...'" error. I also don't think we should catch FilteredLookupError and LookupError from the changelog.rev() call, for the same reason as above: If a namespace returns a node that doesn't exist, we should provide a more helpful exception than "unknown revision '...'".

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.

rebase: remove unnecessary and incorrect handling of nullid We used to write a nullid as hex to the rebase state file and interpret it as the "todo" state (value -1). However, when reading it, we compared the string value to (binary) nullid, which would of course not match. AFAICT, it still worked because when the read nodeid did not match nullid (which, again, it didn't), we'd use the normal path which did repo[<hex nullid>].rev(), and that also happens to return -1. It seems to have been this way ever since 9972758ab4c5 (rebase: handle revtodo as a special value when storing/restoring state, 2014-12-02).
