util: add sort helper

remove: work directly off status This allows us to use a single directory walk and to trivially ignore unknown files. The resulting code is also easier to follow.

status: clean up all users for unknown files

churn: major refactor - use contexts - use ui.pushbuffer and patch.diff to greatly simplify patch generation - simplify diff counting logic - fold all the counting functions together - simplify progress math - simplify padding function - kill graph helper function - simplify alias reading - use Schwartzian transform on stats - change some notes to debugs

Check that git patches only touch files under root

purge: cleanup - remove casefolding check, no longer needed - fold error function into remove - simplify eol logic - remove force logic and parameters

dirstate: improve case-folding logic - return normalized form in directory walk - track normalized form in known

dirstate: fold statwalk and walk

purge: use status

repo.status: eliminate list_

verify: lots of refactoring - simplify finding first bad rev - no need to count changesets - add exc function to simplify exception handling - combine checksize and checkversion to checklog - unify missing revlog detection in checklog - add checkentry to consolidate - linkrev lookup - detailed check of linkrev - detailed check of parents - duplicate checking - use checkentry for changelog, manifest, and files - simplify havecl and havemf - track all changesets refering to a manifest - move unnamed file check somewhere more useful - reorder crosschecks - fix filenodes crosscheck and add exception handling - check unpacked size field

verify: add some local variables

add __len__ and __iter__ methods to repo and revlog

manifest: remove execf/linkf methods

make debugrename work on p1, not tip

use repo[changeid] to get a changectx

rename checkfolding to checkcase

dirstate: remove unused folding function

context: remove islink and isexec methods

simplify flag handling add _checklink var to dirstate introduce dirstate.flagfunc switch users of util.execfunc/linkfunc to flagfunc change manifestdict.set to take a flags string change ctx.fileflags to ctx.flags change gitmode func to a dict remove util.execfunc/linkfunc

context: clean up parents()

context: simplify changeid logic

use repo.changectx(None) to get a workingctx

context: avoid using None for working parent

use repo.changectx rather than context.changectx

context: consistently return p1 context for None

lookup: optimize '.' Remove error messages as behavior is documented in hg help revs

Remove RSS/atom links from coal/paper index

Improve archive links in coal/paper index

graph: fix JavaScript issues to make it work on IE
