changelog: fix bug in heads computation This patch refactors the native computation of heads. It fixes a bug where filtered heads in the pending index could be returned by the native code despite their filtering.

changelog: change input type of index_get_parents We were wrongfully using int instead of Py_ssize_t for the revision number.

branch: don't warn about branches if repository has multiple branches already This warning exists to prevent git users from prematurely polluting their namespace when trying out Mercurial. But for repos that already have multiple branches, understanding what branches are is not optional so we should just shut up.

transaction: really fix _addbackupentry key usage (issue4684) The fix in fd905b2bea59 is actually wrong. We now use the filename to match what '_addentry'. This whole untested code is quite suspicious. This seems to point that no one is ever running 'tr.find' for a backup file.

largefiles: avoid match.files() in conditions See 9789b4a7c595 (match: introduce boolean prefix() method, 2014-10-28) for reasons to avoid match.files() in conditions.

largefiles: pass in whole matcher to getstandinmatcher() The choice between the "always" case and the other case is done in getstandinmatcher() and the next patch will change how it's determined based on the matcher, so let's prepare by passing in the matcher, not just the matcher's files.

largefiles: drop unused 'pats' parameter from getstandinmatcher() The parameter wasn't used even when it was imported from elsewhere in cfccd3bee7b3 (hgext: add largefiles extension, 2011-09-24).

devel: rename 'all' to 'all-warnings' (BC) We have started to isolate extra usecases for developer-only output that is not a warning. As the section has the fairly generic name 'devel' it makes sense to tuck them there. As a result, 'all' becomes a bit misleading so we rename it to 'all-warnings'. This will break some developer setups but the tests are still fine and developers will likely spot this change.

copies: document hack for adding '' to set of dirs The root directory is not normally added to 'dirs' instances (although I think it should be). In copies.mergecopies, we call dirname() to get the directory of a path and then check for containment in the 'dirs' instances ('d1' and 'd2'). In order to easily handle files in the root directory, '/' is added to d1/d2. This results in the empty string being added to the sets, since what comes before the slash in '/' is an empty string. This seems less than obvious, so let's document it.

test-revset: update test that isn't broken on default branch "X or wdir()" just works because the default branch includes 40a2cf1c765b.

pathutil: demote two local functions to just be forwards We retain the forwards because it helps code be more ignorant of implementation details, but use forwards instead of our own method definitions since we don't need any truly custom behavior for now.

pathutil: restate dirname and join as forwards to posixpath I've done this as its own step so that it's easy to see that the posixpath implementations pass the doctests in this package. In a future patch I'll just make these pure forwards of the methods so that things using pathutil can be oblivious to the posix nature of these functions.

help: add documentation on include: and subinclude: Adds some help text about the new include: and subinclude: match syntax.

match: enable 'subinclude:' syntax This adds a new rule syntax that allows the user to include a pattern file, but only have those patterns match against files underneath the subdirectory of the pattern file. This is useful when you have nested projects in a repository and the inner projects wants to set up ignore rules that won't affect other projects in the repository. It is also useful in high commit rate repositories for removing the root .hgignore as a point of contention.

copies: switch to using pathutil.dirname copies had it's own dirname implementation. Now that pathutils has a common one, let's use that instead.
