tests: add missing no-outer-repo requirements Outer repos (if any) will now never be touched by the tests. But it is better to run without any repos around the tmp directory.

tests: convert some 'hghave no-outer-repo' to #if In some places we instead use 'hg init' to create a well-known outer repo without any special extensions or other config settings.

strip: incrementally update the branchheads cache after a strip This function augments strip to incrementally update the branchheads cache rather than recompute it from scratch. This speeds up the performance of strip and rebase on repos with long history. The performance optimization only happens if the revisions stripped are all on the same branch and the parents of the stripped revisions are also on that same branch. This adds a few test cases, particularly one that reproduces the extra heads that mpm observed.

localrepo: convert _updatebranchcache from nodespace to revspace _updatebranchcache used to use revlog.reachable. After the switch to revlog.ancestors, we can now clean it up a bit and switch the algorithm from nodes to revs.

discovery: convert legacy part of checkheads to revs from nodes After a recent switch from revlog.reachable to revlog.ancestors, clean up this old call site, switching it from nodes to revs.

transplant: convert applied() algorithm from nodes to revs After a recent switch from revlog.reachable to revlog.ancestors, clean up the code a bit to use revs rather than nodes.

revlog: remove reachable and switch call sites to ancestors This change does a trivial conversion of callsites to ancestors. Followon diffs will switch the callsites over to revs.

revlog: add incancestors, a version of ancestors that includes revs listed ancestors() returns the ancestors of revs provided. This func is like that except it also includes the revs themselves in the total set of revs generated.

scmutil: change canonpath to use util.samefile (issue2167) Fixes (on Windows in cmd.exe): $ hg -R v:\x\a status V:\x\a\bar abort: V:\x\a\bar not under root where v:\x\a is a valid repository with a checked-out file "bar" (Note the difference in casing: "v:\" versus "V:\")

win32.py: let samefile and samedevice work on directories too

rebase: do not add second parent to rebased changeset (drop detach option) (BC) Rebase now behaves as if --detach was always passed. Non-merges are rebased as non-merges, regardless of their parent being an ancestor of the destination. Merges will usually be rebased as merges unless both of their parents are ancestors of the destination, or one of their parents is pruned when rebased. This only alters the behavior of rebase when using the --source/--rev options. --detach option is deprecated. All test changes were carefully validated.

zsh completion: catch up with 2.2 commands and options * add completion for phase and graft core commands * add completion for rebase extension * add new options for already defined commands: * commit --amend * import --bypass * manifest --all * merge --tool * revert -C (short for --no-backup) * qpush --exact [mq] * email --body [patchbomb]

revset: add a utility for obtaining the source of a given rev graft, transplant and rebase all embed a different type of source marker in extra, and each with a different name. The current implementation of each is such that there will never be more than one of these markers on a node. Note that the rebase marker can only be resolved if the source is still present, which excludes the typical rebase usage (without --keep) from consideration (unless the resulting bundle in strip-backup is overlayed). There probably isn't any reason to use rebase --keep as a substitute for transplant or graft at this point, but maybe there was at one point and there are even a few rebases in the hg repo, so it may be of historical interest.

revset: add a predicate for finding converted changesets This selects changesets added because of repo conversions. For example hg log -r "converted()" # all csets created by a convertion hg log -r "converted(rev)" # the cset converted from rev in the src repo The converted(rev) form is analogous to remote(id), where the remote repo is the source of the conversion. This can be useful for cross referencing an old repository into the current one. The source revision may be the short changeset hash or the full hash from the source repository. The local identifier isn't useful. An interesting ramification of this is if a short revision is specified, it may cause more than one changeset to be selected. (e.g. converted(6) matches changesets with a convert_revision field of 6e..e and 67..0) The convert.hg.saverev option must have been specified when converting the hg source repository for this to work. The other sources automatically embed the converted marker.
