ignore: process hgignore files in deterministic order Previously, we processed them in whatever order the dict iterator gave us.

ignore: only read an ignore file once

ignore: refactor ignore into two functions This prepares us for eventually being able to hash the list of patterns in use.

clfilter: fix `nodemap` usage in `getbundle` With the current implementation, `changelog.nodemap` is not filtered. So some filtered changeset in common are not filtered by `n in nodemap`. This leads to crash lower in the stack when the bundle generation try to access those node on a filtered changelog.

test: fix truncated comment in test The push is made to ensure repository are related. The comment in the initial changeset got truncated somehow.

clfilter: ensure context raise RepoLookupError when the revision is filtered Currently the code path of `changectx(filteredrepo, rev)` call `filteredrepo.changelog.node(rev)`. When `rev` is filtered this raise an unhandled `IndexError`. This case now raise a `RepoLookupError` as other error case do.

revlog: remove incancestors since it is no longer used

transplant: replace incancestors uses with ancestors

revlog.ancestors: add support for including revs This is in preparation for an upcoming refactoring. This also fixes a bug in incancestors, where if an element of revs was an ancestor of another it would be generated twice.

perf: add command to test performance of membership in ancestor set The new command, perfancestorset, takes an argument denoting which revset to test the membership of. Currently this runs through all the ancestors and converts them into a set. The primary purpose of having this is to compare this approach, currently used in several places, against the upcoming lazy approach.

ancestor: move missingancestors doctest out into a separate file This is in preparation for upcoming patches which will reuse the same graph for tests.

dirstate: remove obsolete comment from setbranch This comment should have been removed in b74361cf7c0a, when the call to scmutil.checknewlabel was removed.

dirstate: don't rename branch file if writing it failed

commands: 'hg bookmark NAME' should work even with ui.strict=True Before this patch, enabling strict command processing (ui.strict=True) meant that 'hg bookmark NAME', as referenced several places in the documentation, would not work. This adds 'bookmark' as an explicit alias to 'bookmarks'.

tests: improve test-mv-cp-st-diff.t readability

obsolete: refuse to push divergent changeset As other troubles `unstable` and `bumped`. Followup patches may simplify the push code with unification of "obsolescence troubles" handling.

obsolete: add a divergent method on context The same we have `unstable` and `bumped`. Convenient method to access troubles information in general may land later. This get actual use and testing in the next changesets.

obsolete: add revset and test for divergent changesets This changesets add a new `divergent()` revset similar to `unstable()` and `bumped()` one. Introducting this revset allows actuall test of the divergent detection.

obsolete: detect divergent changesets Divergent changeset are final successors (non obsolete) of a changeset who compete with another set of final successors for this same changeset. For example if you have two obsolescence markers A -> B and A -> C, B and C are both "divergent" because they compete to be the one true successors of A. Public revision can't be divergent. This function is used and tested in the next changeset.

obsolete: drop successors sets which are subset of another one If both "(B,)" and "(B, C)" are successors set of "A", "(B,)" is dropped. We won't be interrested in detection such divergence scenario.

obsolete: compute successors set Successors set are an important part of obsolescence. It is necessary to detect and solve divergence situation. This changeset add a core function to compute them, a debug command to audit them and solid test on the concept. Check function docstring for details about the concept.

mq: don't fail when removing a patch without patch file from series file

largefiles: align rm warnings with warnings used in core

merge with stable

largefiles: commit directories that only contain largefiles (issue3548) If we pass a directory to commit whose only commitable files are largefiles, the core commit code aborts before finding the largefiles. So we do the following: For directories that only have largefiles as matches, we explicitly add the largefiles to the matchlist and remove the directory. In other cases, we leave the match list unmodified.

revset.children: ignore rev numbers that are too low This replaces unnecessary parentrevs() calls with calculating min(parentset). Even though the min operation is O(size of parentset), since parentrevs is relatively expensive, this tradeoff almost always works in our favour. In a repository with over 400,000 changesets, hg perfrevset "children(X)" takes: Set X Before After -1 0.51s 0.06s -1000: 0.55s 0.08s -10000: 0.56s 0.10s -100000: 0.60s 0.25s -100000:-99000 0.55s 0.19s 0:100000 0.60s 0.61s all() 0.72s 0.74s The relative performance is similar for Mercurial's own repository -- several times faster in most cases, slightly slower for revisions close to 0 and all().

perf: add a command to measure revset performance
