merge: remove useless dirstate.normallookup() invocation in applyupdates()

Explicit 'dirstate.normallookup()' invocation via 'dirtysubstate()' in
'applyupdates()' is useless now, because previous patch fixed the
relevant issue by writing in-memory dirstate changes out at the end of
dirty check.

'dirstate.normallookup()' invocation was introduced by 6becb9dbca25 to
avoid occasional test failure. This is partial backout of it (added
tests are still left).

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)
  dir1\x008b3ffd73f901e83304c83d33132c8e774ceac44ed (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 (glob)
  dir1/b (glob)
  dir1/dir1/a (glob)
  dir1/dir1/b (glob)
  dir1/dir2/a (glob)
  dir1/dir2/b (glob)
  e

Revision is not created for unchanged directory

  $ mkdir dir2
  $ echo 3 > dir2/a
  $ hg add dir2
  adding dir2/a (glob)
  $ 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 (glob)
  removing dir1/dir1/b (glob)
  $ 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 (glob)
  dir1/b (glob)
  dir1/dir1/a (glob)
  dir1/dir1/b (glob)
  dir1/dir2/a (glob)
  dir1/dir2/b (glob)

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 (glob)
  $ hg ci -m 'merge, keeping parent 1'
  $ hg debugindex --dir dir2 > after
  $ diff before after
  $ rm before after

Merge keeping directory from parent 2 does not create revlog entry. (Note that
dir2's manifest does change, but only because dir2/a's filelog changes.)

  $ hg co 'desc("modify dir2/a")'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debugindex --dir dir1 > before
  $ hg merge 'desc("modify dir1/a")'

Create flat source repo for tests with mixed flat/tree manifests

  $ cd ..
  $ hg init repo-flat
  $ cd repo-flat

Create a few commits with flat manifest

  $ echo 0 > a
  $ echo 0 > b
  $ echo 0 > e
  $ for d in dir1 dir1/dir1 dir1/dir2 dir2
  > do
  >   mkdir $d
  >   echo 0 > $d/a

  $ hg ci -Aqm initial

  $ echo 1 > a
  $ echo 1 > dir1/a
  $ echo 1 > dir1/dir1/a
  $ hg ci -Aqm 'modify on branch 1'

  $ hg co 0
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 2 > b
  $ echo 2 > dir1/b
  $ echo 2 > dir1/dir1/b
  $ hg ci -Aqm 'modify on branch 2'

  $ hg merge 1
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg ci -m 'merge of flat manifests to new flat manifest'

Create clone with tree manifests enabled

  $ cd ..
  $ hg clone --pull --config experimental.treemanifest=1 repo-flat repo-mixed
  requesting all changes
  adding changesets
  adding manifests
  adding file changes
  added 4 changesets with 17 changes to 11 files
  updating to branch default
  11 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ cd repo-mixed
  $ test -f .hg/store/meta
  [1]
  $ grep treemanifest .hg/requires
  treemanifest

Commit should store revlog per directory

  $ hg co 1
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 3 > a
  $ echo 3 > dir1/a
  $ echo 3 > dir1/dir1/a
  $ hg ci -m 'first tree'

Merge of two trees

  $ hg co 2
  6 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg merge 1
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved
  (branch merge, don't forget to commit)
  $ hg ci -m 'merge of flat manifests to new tree manifest'
  created new head
  $ hg diff -r 3

Parent of tree root manifest should be flat manifest, and two for merge

  $ hg debugindex -m
     rev    offset  length   base linkrev nodeid       p1           p2
       0         0      80      0       0 40536115ed9e 000000000000 000000000000

Status across flat/tree boundary should work

  $ hg status --rev '.^' --rev .
  M a
  M dir1/a
  M dir1/dir1/a


Turning off treemanifest config has no effect

  $ hg debugindex .hg/store/meta/dir1/00manifest.i
     rev    offset  length   base linkrev nodeid       p1           p2

Create deeper repo with tree manifests.

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

  $ mkdir a
  $ mkdir b
  $ mkdir b/bar
  $ mkdir b/bar/orange
  $ mkdir b/bar/orange/fly
  $ mkdir b/foo
  $ mkdir b/foo/apple
  $ mkdir b/foo/apple/bees

  $ touch a/one.txt
  $ touch a/two.txt
  $ touch b/bar/fruits.txt
  $ touch b/bar/orange/fly/gnat.py
  $ touch b/bar/orange/fly/housefly.txt
  $ touch b/foo/apple/bees/flower.py
  $ touch c.txt
  $ touch d.py

  $ hg ci -Aqm 'initial'

We'll see that visitdir works by removing some treemanifest revlogs and running
the files command with various parameters.

Test files from the root.

  $ hg files -r .
  a/one.txt (glob)
  a/two.txt (glob)
  b/bar/fruits.txt (glob)
  b/bar/orange/fly/gnat.py (glob)
  b/bar/orange/fly/housefly.txt (glob)
  b/foo/apple/bees/flower.py (glob)
  c.txt
  d.py

Excludes with a glob should not exclude everything from the glob's root

  $ hg files -r . -X 'b/fo?' b
  b/bar/fruits.txt (glob)
  b/bar/orange/fly/gnat.py (glob)
  b/bar/orange/fly/housefly.txt (glob)

Test files for a subdirectory.

  $ mv .hg/store/meta/a oldmf
  $ hg files -r . b
  b/bar/fruits.txt (glob)
  b/bar/orange/fly/gnat.py (glob)
  b/bar/orange/fly/housefly.txt (glob)
  b/foo/apple/bees/flower.py (glob)
  $ mv oldmf .hg/store/meta/a

Test files with just includes and excludes.

  $ mv .hg/store/meta/a oldmf
  $ mv .hg/store/meta/b/bar/orange/fly oldmf2
  $ mv .hg/store/meta/b/foo/apple/bees oldmf3
  $ hg files -r . -I path:b/bar -X path:b/bar/orange/fly -I path:b/foo -X path:b/foo/apple/bees
  b/bar/fruits.txt (glob)
  $ mv oldmf .hg/store/meta/a
  $ mv oldmf2 .hg/store/meta/b/bar/orange/fly
  $ mv oldmf3 .hg/store/meta/b/foo/apple/bees

Test files for a subdirectory, excluding a directory within it.

  $ mv .hg/store/meta/a oldmf
  $ mv .hg/store/meta/b/foo oldmf2
  $ hg files -r . -X path:b/foo b
  b/bar/fruits.txt (glob)
  b/bar/orange/fly/gnat.py (glob)
  b/bar/orange/fly/housefly.txt (glob)
  $ mv oldmf .hg/store/meta/a
  $ mv oldmf2 .hg/store/meta/b/foo

Test files for a sub directory, including only a directory within it, and
including an unrelated directory.

  $ mv .hg/store/meta/a oldmf
  $ mv .hg/store/meta/b/foo oldmf2
  $ hg files -r . -I path:b/bar/orange -I path:a b
  b/bar/orange/fly/gnat.py (glob)
  b/bar/orange/fly/housefly.txt (glob)
  $ mv oldmf .hg/store/meta/a
  $ mv oldmf2 .hg/store/meta/b/foo

Test files for a pattern, including a directory, and excluding a directory
within that.

  $ mv .hg/store/meta/a oldmf
  $ mv .hg/store/meta/b/foo oldmf2
  $ mv .hg/store/meta/b/bar/orange oldmf3
  $ hg files -r . glob:**.txt -I path:b/bar -X path:b/bar/orange
  b/bar/fruits.txt (glob)
  $ mv oldmf .hg/store/meta/a
  $ mv oldmf2 .hg/store/meta/b/foo
  $ mv oldmf3 .hg/store/meta/b/bar/orange
