phases: invalidate the phases set less often on retract boundary

We already have the information to update the phase set, so we do so directly
instead of invalidating the cache.

This show a sizeable speedup in our `perf::unbundle` benchmark on the
many-draft mozilla-try repository.

test "hg status" with "directory pattern" which matches against files
only known on target revision.

the directory matching against specified pattern should be removed,
because directory existence prevents 'dirstate.walk()' from showing
warning message about such pattern.

Status after move overwriting a file (issue4458)

  $ rm *.orig

without force

  $ hg rm a
  $ hg st --copies

  $ hg mv b a
  $ hg st --copies

Other "bug" highlight, the revision status does not report the copy information.
This is buggy behavior.

  $ hg commit -m 'blah'
  $ hg st --copies --change .
  M a

using log status template, the copy information is displayed correctly.
  $ hg log -Tstatus -r. -C
  changeset:   1:6685fde43d21

  $ cd ..

Make sure .hg doesn't show up even as a symlink

  $ hg init repo0
  $ mkdir symlink-repo0
  $ cd symlink-repo0
  $ ln -s ../repo0/.hg
  $ hg status

If the size hasn’t changed but mtime has, status needs to read the contents
of the file to check whether it has changed

  $ echo 1 > a
  $ echo 1 > b
  $ touch -t 200102030000 a b
  $ hg commit -Aqm '#0'
  $ echo 2 > a
  $ touch -t 200102040000 a b
  $ hg status
  M a

Asking specifically for the status of a deleted/removed file

  $ rm a
  $ rm b
  $ hg status a
  ! a
  $ hg rm a
  $ hg rm b
  $ hg status a
  R a
  $ hg commit -qm '#1'
  $ hg status a
  a: $ENOENT$

Check using include flag with pattern when status does not need to traverse
the working directory (issue6483)

  $ cd ..
  $ hg init issue6483
  $ cd issue6483
  $ touch a.py b.rs
  $ hg add a.py b.rs
  $ hg st -aI "*.py"
  A a.py

Also check exclude pattern

  $ hg st -aX "*.rs"
  A a.py

issue6335
When a directory containing a tracked file gets symlinked, as of 5.8
`hg st` only gives the correct answer about clean (or deleted) files
if also listing unknowns.
The tree-based dirstate and status algorithm fix this:

#if symlink no-dirstate-v1 rust

  $ cd ..
  $ hg init issue6335
  $ cd issue6335
  $ mkdir foo
  $ touch foo/a
  $ hg ci -Ama
  adding foo/a
  $ mv foo bar
  $ ln -s bar foo
  $ hg status
  ! foo/a
  ? bar/a
  ? foo

  $ hg status -c  # incorrect output without the Rust implementation
  $ hg status -cu
  ? bar/a
  ? foo
  $ hg status -d  # incorrect output without the Rust implementation
  ! foo/a
  $ hg status -du
  ! foo/a
  ? bar/a
  ? foo

#endif


Create a repo with files in each possible status

  $ cd ..
  $ hg init repo7
  $ cd repo7
  $ mkdir subdir
  $ touch clean modified deleted removed
  $ touch subdir/clean subdir/modified subdir/deleted subdir/removed
  $ echo ignored > .hgignore
  $ hg ci -Aqm '#0'
  $ echo 1 > modified
  $ echo 1 > subdir/modified
  $ rm deleted
  $ rm subdir/deleted
  $ hg rm removed
  $ hg rm subdir/removed
  $ touch unknown ignored
  $ touch subdir/unknown subdir/ignored

Check the output

  $ hg status
  M modified
  M subdir/modified
  R removed
  R subdir/removed
  ! deleted
  ! subdir/deleted
  ? subdir/unknown
  ? unknown

  $ hg status -mard
  M modified
  M subdir/modified
  R removed
  R subdir/removed
  ! deleted
  ! subdir/deleted

  $ hg status -A
  M modified
  M subdir/modified
  R removed
  R subdir/removed
  ! deleted
  ! subdir/deleted
  ? subdir/unknown
  ? unknown
  I ignored
  I subdir/ignored
  C .hgignore
  C clean
  C subdir/clean

Note: `hg status some-name` creates a patternmatcher which is not supported
yet by the Rust implementation of status, but includematcher is supported.
--include is used below for that reason

#if unix-permissions

Not having permission to read a directory that contains tracked files makes
status emit a warning then behave as if the directory was empty or removed
entirely:

  $ chmod 0 subdir
  $ hg status --include subdir
  subdir: $EACCES$
  R subdir/removed
  ! subdir/clean
  ! subdir/deleted
  ! subdir/modified
  $ chmod 755 subdir

#endif

Remove a directory that contains tracked files

  $ rm -r subdir
  $ hg status --include subdir
  R subdir/removed
  ! subdir/clean
  ! subdir/deleted
  ! subdir/modified

… and replace it by a file

  $ touch subdir
  $ hg status --include subdir
  R subdir/removed
  ! subdir/clean
  ! subdir/deleted
  ! subdir/modified
  ? subdir

Replaced a deleted or removed file with a directory

  $ mkdir deleted removed
  $ touch deleted/1 removed/1
  $ hg status --include deleted --include removed
  R removed
  ! deleted
  ? deleted/1
  ? removed/1
  $ hg add removed/1
  $ hg status --include deleted --include removed
  A removed/1
  R removed
  ! deleted
  ? deleted/1

Deeply nested files in an ignored directory are still listed on request

  $ echo ignored-dir >> .hgignore
  $ mkdir ignored-dir
  $ mkdir ignored-dir/subdir
  $ touch ignored-dir/subdir/1
  $ hg status --ignored
  I ignored
  I ignored-dir/subdir/1

Check using include flag while listing ignored composes correctly (issue6514)

  $ cd ..
  $ hg init issue6514
  $ cd issue6514
  $ mkdir ignored-folder
  $ touch A.hs B.hs C.hs ignored-folder/other.txt ignored-folder/ctest.hs
  $ cat >.hgignore <<EOF
  > A.hs
  > B.hs
  > ignored-folder/

  $ hg st -i -I 're:.*\.hs$'

Check read_dir caching

  $ cd ..
  $ hg init repo8
  $ cd repo8
  $ mkdir subdir
  $ touch subdir/a subdir/b
  $ hg ci -Aqm '#0'

The cached mtime is initially unset

  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 unset               subdir

It is still not set when there are unknown files

  $ touch subdir/unknown
  $ hg status
  ? subdir/unknown
  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 unset               subdir

Now the directory is eligible for caching, so its mtime is saved in the dirstate

  $ rm subdir/unknown
  $ sleep 0.1 # ensure the kernel’s internal clock for mtimes has ticked
  $ hg status
  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 set                 subdir

This time the command should be ever so slightly faster since it does not need `read_dir("subdir")`

  $ hg status

Creating a new file changes the directory’s mtime, invalidating the cache

  $ touch subdir/unknown
  $ hg status
  ? subdir/unknown

  $ rm subdir/unknown
  $ hg status

Removing a node from the dirstate resets the cache for its parent directory

  $ hg forget subdir/a
  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 set                 subdir
  $ hg ci -qm '#1'
  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 unset               subdir
  $ hg status
  ? subdir/a

Changing the hgignore rules makes us recompute the status (and rewrite the dirstate).

  $ rm subdir/a
  $ mkdir another-subdir
  $ touch another-subdir/something-else

  $ cat > "$TESTTMP"/extra-hgignore <<EOF
  > something-else
  > EOF

  $ hg status --config ui.ignore.global="$TESTTMP"/extra-hgignore
  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 set                 subdir

  $ hg status
  ? another-subdir/something-else

One invocation of status is enough to populate the cache even if it's invalidated
in the same run.

  $ hg debugdirstate --all --no-dates | grep '^ '
      0         -1 set                 subdir

Test copy source formatting.
  $ cd ..
  $ hg init copy-source-repo
  $ cd copy-source-repo
  $ mkdir -p foo/bar
  $ cd foo/bar
  $ touch file
  $ hg addremove
  adding foo/bar/file
  $ hg commit -m 'add file'
  $ hg mv file copy

Copy source respects relative path setting.
  $ hg st --config ui.statuscopies=true --config commands.status.relative=true
  A copy
    file
  R file

Copy source is not shown when --no-status is passed.
  $ hg st --config ui.statuscopies=true --no-status
  foo/bar/copy
  foo/bar/file
