tests: add testing for diff.showfunc The diff.showfunc config knob did not have coverage before.

manifest: make manifest.intersectfiles() internal manifest.intersectfiles() is just a utility used by manifest.matches(), and a future commit removes intersectfiles for treemanifest for optimization purposes. This commit makes the intersectfiles methods on manifestdict and treemanifest internal, and converts its test to a more generic testMatches(), which has the exact same coverage.

win32: add comment about WinError Prevent reintroducing the bug that was added in e34106fa0dc3 (and fixed with a2285e2fc949).

templates: fix "log -q" output of phases style It had the same problem as 6136704b975d, name conflicts of {node} keyword.

record_curses: fix ui bug for newly added file With record's curses interface toggling and untoggling a newly added file would lead to a confusing UI (the header was marked as partial and the hunks as unselected). Tested additionally using the curses interface with newly added, removed and modified files in a test repo.

import-checker: rotatecycle is actually the canonical cycle key So refactor to drop cyclekey().

import-checker: make search algorithm non-recursive breadth-first Breadth-first allows finding the shortest cycle including the starting module. This lets us terminate our search early when we've discovered shorter paths already. This gives a tremendous speed-up to the cycle-finding portion of the test, dropping total runtime from 39s to 3s.

import-checker: drop set() from cyclekey()

import-checker: drop duplicate element from cycle This will allow optimizing cyclekey creation

import-checker: fix rotatecycle It was duplicating the last element sometimes.

dirs.addpath: rework algorithm to search forward This improves performance because it uses strchr rather than a loop. For LLVM/clang version "Apple LLVM version 6.0 (clang-600.0.56) (based on LLVM 3.5svn)" on OS X, for a repo with over 200,000 files, this improves perfdirs from 0.248 seconds to 0.230 (7.3%) For gcc 4.4.6 on Linux, for a test repo with over 500,000 files, this improves perfdirs from 0.704 seconds to 0.658 (6.5%).

changeset_printer: use changectx to get status tuple log.parents() can't handle wdir() revision. Because repo.status() creates ctx objects, there would be no benefit to get parent node from changelog.

changeset_printer: replace _meaningful_parentrevs() by changeset_templater's Because changeset_printer needs pctx object anyway, there would be no benefit to avoid creation of pctx in _meaningful_parentrevs().

changeset_printer: use context objects consistently to show parents This prepares for merging changeset_printer._maningful_parentrevs() with changeset_templater's.

children: don't pass filectx to displayer displayer doesn't want a fctx but a ctx. It failed with -Tdefault template. Traceback (most recent call last): ... File "mercurial/templatekw.py", line 212, in showbookmarks bookmarks = args['ctx'].bookmarks() AttributeError: 'filectx' object has no attribute 'bookmarks'

verify: add a note about a paleo-bug In the very early days of hg, it was possible to commit /dev/null because our patch importer was too simple. Repos from this era may still exist, add a note about why we ignore this name.

cmdutil: remove some excess vertical whitespace

revert: move calculation of targetsubs earlier

shelve: add interactive mode This allows us to shelve selectively part of the changes of the workdir

shelve: add interactive mode command line option

record: change return value of recording code It makes it easier to include interactive mode to more commands that require to get a reference to the newly created node

revert: fix --interactive on local modification (issue4576) We were moving files during the backup phase and it was incompatible with the way record/crecord is working

largefiles: remove useless overrideupdate Now, "overrideupdate()" wrapping "hg update" is useless, because "workingctx.dirty() and raising Abort" in "hg update" was replaced by "cmdutil.bailifchanged()" in the previous patch, and the latter can detect changes of largefiles in the working directory.

update: replace workingctx.dirty and raising Abort by cmdutil.bailifchanged This patch makes wrapping "commands.update()" by largefiles extension useless, because "cmdutil.bailifchanged()" can detect changes of largefiles in the working directory. This patch also changes test-update-branches.t, because "cmdutil.bailifchanged()" shows more detailed information about dirty-ness of the working directory than "workingctx.dirty()".
