pull: pass rev to check out as integer to postincoming() I don't know if there's ever been a need for it to be a string (it's been like that since 02f40b2ece3f (commands: use rev from remote repo when updating as part of a pull, 2009-10-21)). I'm soon going to require it to be an integer, so let's fix this first. Differential Revision: https://phab.mercurial-scm.org/D3086

children: support specifying revision by revset Same reason as the previous patch. Differential Revision: https://phab.mercurial-scm.org/D3085

heads: add support for specifying branches by revset Before this commit, e.g. "hg heads .^" would fail with: abort: unknown revision '.^'! Like the previous patch, I don't care about the command itself (I don't think I had ever used it before), I'm just cleaning up uses of repo[<string>].

perf: make perfmanifest and perfnodelookup work with revsets They were using repo[rev], which only works with a single symbol (e.g. "." or "my-bookmark"), not general revsets. Switch them to scmutil.revsingle() so they can also be used with e.g. ".^". I don't actually care about these commands, but I want to remove uses of repo[<string>].

context: use revsymbol() in "merge.preferancestor" code Differential Revision: https://phab.mercurial-scm.org/D3082

wireproto: use repo.lookup() for lookup command I'm trying to reduce use of repo[<string>] and this seems like an obvious place to use repo.lookup(). Differential Revision: https://phab.mercurial-scm.org/D3081

localrepo: use revsymbol in lookupbranch() too lookupbranch() takes a string that comes from the CLI, so scmutil.revsymbol() is appropriate for looking it up. Differential Revision: https://phab.mercurial-scm.org/D3080

localrepo: drop "remote" argument from lookupbranch() (API) According to `hg grep --all lookupbranch`, the "remote" argument has never been used ever since it was introduced in ca739acf1a98 (commands: add more robust support for 'hg log -b' (issue2078), 2010-04-12).

revset: use revsymbol() for checking if a symbol is valid Differential Revision: https://phab.mercurial-scm.org/D3078

tests: disable tests for advanced clone features with simple store There are a handful of test failures in the simple store with regards to stream clones. Fixing them will require a lot of conditional output. Disabling the tests wholesale is easier at this juncture. Differential Revision: https://phab.mercurial-scm.org/D3064
