narrowspec: move module into core

Having support for parsing the narrow specification in core is
necessary for moving many other parts of narrow to core.

We do still want to harmonize the narrow spec with the sparse
spec. And the format needs to be documented. But this shouldn't
hold up the code moving to core.

Set up repo

  $ hg --config experimental.treemanifest=True init repo
  $ cd repo

Requirements get set on init

  $ grep treemanifest .hg/requires
  treemanifest

Without directories, looks like any other repo

  $ echo 0 > a
  $ echo 0 > b
  $ hg ci -Aqm initial
  $ hg debugdata -m 0
  a\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
  b\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)

Submanifest is stored in separate revlog

  $ mkdir dir1
  $ echo 1 > dir1/a
  $ echo 1 > dir1/b
  $ echo 1 > e
  $ hg ci -Aqm 'add dir1'
  $ hg debugdata -m 1
  a\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)
  b\x00362fef284ce2ca02aecc8de6d5e8a1c3af0556fe (esc)

  e\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)
  $ hg debugdata --dir dir1 0
  a\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)
  b\x00b8e02f6433738021a065f94175c7cd23db5f05be (esc)

Can add nested directories

  $ mkdir dir1/dir1
  $ echo 2 > dir1/dir1/a
  $ echo 2 > dir1/dir1/b
  $ mkdir dir1/dir2
  $ echo 2 > dir1/dir2/a
  $ echo 2 > dir1/dir2/b
  $ hg ci -Aqm 'add dir1/dir1'
  $ hg files -r .
  a
  b
  dir1/a
  dir1/b
  dir1/dir1/a
  dir1/dir1/b
  dir1/dir2/a
  dir1/dir2/b
  e

The manifest command works

  $ hg manifest
  a
  b
  dir1/a
  dir1/b
  dir1/dir1/a
  dir1/dir1/b
  dir1/dir2/a
  dir1/dir2/b
  e

Revision is not created for unchanged directory

  $ mkdir dir2
  $ echo 3 > dir2/a
  $ hg add dir2
  adding dir2/a
  $ hg debugindex --dir dir1 > before
  $ hg ci -qm 'add dir2'
  $ hg debugindex --dir dir1 > after
  $ diff before after
  $ rm before after

Removing directory does not create an revlog entry

  $ hg rm dir1/dir1
  removing dir1/dir1/a
  removing dir1/dir1/b
  $ hg debugindex --dir dir1/dir1 > before
  $ hg ci -qm 'remove dir1/dir1'
  $ hg debugindex --dir dir1/dir1 > after
  $ diff before after
  $ rm before after

Check that hg files (calls treemanifest.walk()) works
without loading all directory revlogs

  $ hg co 'desc("add dir2")'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ mv .hg/store/meta/dir2 .hg/store/meta/dir2-backup
  $ hg files -r . dir1
  dir1/a
  dir1/b
  dir1/dir1/a
  dir1/dir1/b
  dir1/dir2/a
  dir1/dir2/b

Check that status between revisions works (calls treemanifest.matches())
without loading all directory revlogs

  $ hg status --rev 'desc("add dir1")' --rev . dir1
  A dir1/dir1/a
  A dir1/dir1/b
  A dir1/dir2/a
  A dir1/dir2/b
  $ mv .hg/store/meta/dir2-backup .hg/store/meta/dir2

Merge creates 2-parent revision of directory revlog

  $ echo 5 > dir1/a
  $ hg ci -Aqm 'modify dir1/a'
  $ hg co '.^'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 6 > dir1/b
  $ hg ci -Aqm 'modify dir1/b'
  $ hg merge 'desc("modify dir1/a")'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m 'conflict-free merge involving dir1/'

Merge keeping directory from parent 1 does not create revlog entry. (Note that
dir1's manifest does change, but only because dir1/a's filelog changes.)

  $ hg co 'desc("add dir2")'
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 8 > dir2/a
  $ hg ci -m 'modify dir2/a'
  created new head

  $ hg debugindex --dir dir2 > before
  $ hg merge 'desc("modify dir1/a")'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg revert -r 'desc("modify dir2/a")' .
  reverting dir1/a
  $ hg ci -m 'merge, keeping parent 1'
  $ hg debugindex --dir dir2 > after
