localrepo: grab mixedrepostorecache class from 526750cdd02d

On default, Martin von Zweigbergk <[e-mail]> introduced a more
advance filecache decorator. I need this decorator to fix a bug on stable. So I
am grafting the relevant part of 526750cdd02d.

test that a commit clears the merge state.

  $ hg init repo
  $ cd repo

  $ echo foo > file1
  $ echo foo > file2
  $ hg commit -Am 'add files'
  adding file1
  adding file2

  $ echo bar >> file1
  $ echo bar >> file2
  $ hg commit -Am 'append bar to files'

create a second head with conflicting edits

  $ hg up -C 0
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo baz >> file1
  $ echo baz >> file2
  $ hg commit -Am 'append baz to files'
  created new head

create a third head with no conflicting edits
  $ hg up -qC 0
  $ echo foo > file3
  $ hg commit -Am 'add non-conflicting file'
  adding file3
  created new head

failing merge

  $ hg up -qC 2
  $ hg merge --tool=internal:fail 1
  0 files updated, 0 files merged, 0 files removed, 2 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon
  [1]

resolve -l should contain unresolved entries

  $ hg resolve -l
  U file1
  U file2

  $ hg resolve -l --no-status
  file1
  file2

resolving an unknown path should emit a warning, but not for -l

  $ hg resolve -m does-not-exist
  arguments do not match paths that need resolving
  $ hg resolve -l does-not-exist

tell users how they could have used resolve

  $ mkdir nested
  $ cd nested
  $ hg resolve -m file1
  arguments do not match paths that need resolving
  (try: hg resolve -m path:file1)
  $ hg resolve -m file1 filez
  arguments do not match paths that need resolving
  (try: hg resolve -m path:file1 path:filez)
  $ hg resolve -m path:file1 path:filez
  $ hg resolve -l
  R file1
  U file2
  $ hg resolve -l --config ui.relative-paths=yes
  R ../file1
  U ../file2
  $ hg resolve --re-merge filez file2
  arguments do not match paths that need resolving
  (try: hg resolve --re-merge path:filez path:file2)
  $ hg resolve -m filez file2
  arguments do not match paths that need resolving
  (try: hg resolve -m path:filez path:file2)
  $ hg resolve -m path:filez path:file2
  (no more unresolved files)
  $ hg resolve -l
  R file1
  R file2

cleanup
  $ hg resolve -u
  $ cd ..
  $ rmdir nested

(At this point we have r0 creating file1, and sibling commits r1 and r2, which
 modify and delete file1, respectively)

  $ hg merge -r 1
  file 'file1' was deleted in local [working copy] but was modified in other [merge rev].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? u
  0 files updated, 0 files merged, 0 files removed, 1 files unresolved
  use 'hg resolve' to retry unresolved file merges or 'hg merge --abort' to abandon
  [1]
  $ hg resolve --list
  U file1
Because we left it as 'unresolved' the file should still exist.
  $ [ -f file1 ] || echo "File does not exist?"
BC behavior: `hg resolve --mark` accepts that the file is still there, and
doesn't have a problem with this situation.
  $ hg resolve --mark --config commands.resolve.mark-check=abort
  (no more unresolved files)
  $ hg resolve --list
  R file1
The file is still there:
  $ [ -f file1 ] || echo "File does not exist?"
Let's check mark-check=warn:
  $ hg resolve --unmark file1
  $ hg resolve --mark --config commands.resolve.mark-check=warn
  (no more unresolved files)
  $ hg resolve --list
  R file1
The file is still there:
  $ [ -f file1 ] || echo "File does not exist?"
Let's resolve the issue by deleting the file via `hg resolve`
  $ hg resolve --unmark file1
  $ echo 'd' | hg resolve file1 --config ui.interactive=1
  file 'file1' was deleted in local [working copy] but was modified in other [merge rev].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? d
  (no more unresolved files)
  $ hg resolve --list
  R file1
The file is deleted:
  $ [ -f file1 ] && echo "File still exists?" || true
Doing `hg resolve --mark` doesn't break now that the file is missing:
  $ hg resolve --mark --config commands.resolve.mark-check=abort
  (no more unresolved files)
  $ hg resolve --mark --config commands.resolve.mark-check=warn
  (no more unresolved files)
Resurrect the file, and delete it outside of hg:
  $ hg resolve --unmark file1
  $ hg resolve file1
  file 'file1' was deleted in local [working copy] but was modified in other [merge rev].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? u
  [1]
  $ [ -f file1 ] || echo "File does not exist?"
  $ hg resolve --list
  U file1
  $ rm file1
  $ hg resolve --mark --config commands.resolve.mark-check=abort
  (no more unresolved files)
  $ hg resolve --list
  R file1
  $ hg resolve --unmark file1
  $ hg resolve file1
  file 'file1' was deleted in local [working copy] but was modified in other [merge rev].
  What do you want to do?
  use (c)hanged version, leave (d)eleted, or leave (u)nresolved? u
  [1]

  $ hg resolve --list
  U file1
  $ rm file1
  $ hg resolve --mark --config commands.resolve.mark-check=warn
  (no more unresolved files)
  $ hg resolve --list
  R file1


For completeness, let's try that in the opposite direction (merging r2 into r1,
instead of r1 into r2):
  $ hg update -qCr 1
  $ hg merge -r 2
  file 'file1' was deleted in other [merge rev] but was modified in local [working copy].
  What do you want to do?

  R file1
The file is still there:
  $ [ -f file1 ] || echo "File does not exist?"
Let's check mark-check=warn:
  $ hg resolve --unmark file1
  $ hg resolve --mark --config commands.resolve.mark-check=warn
  (no more unresolved files)
  $ hg resolve --list
  R file1
The file is still there:
  $ [ -f file1 ] || echo "File does not exist?"
Let's resolve the issue by deleting the file via `hg resolve`
  $ hg resolve --unmark file1
  $ echo 'd' | hg resolve file1 --config ui.interactive=1
  file 'file1' was deleted in other [merge rev] but was modified in local [working copy].
  What do you want to do?
  use (c)hanged version, (d)elete, or leave (u)nresolved? d
  (no more unresolved files)
  $ hg resolve --list
  R file1
The file is deleted:
  $ [ -f file1 ] && echo "File still exists?" || true
Doing `hg resolve --mark` doesn't break now that the file is missing:
  $ hg resolve --mark --config commands.resolve.mark-check=abort
  (no more unresolved files)
  $ hg resolve --mark --config commands.resolve.mark-check=warn
  (no more unresolved files)
Resurrect the file, and delete it outside of hg:
  $ hg resolve --unmark file1
  $ hg resolve file1
  file 'file1' was deleted in other [merge rev] but was modified in local [working copy].
  What do you want to do?
  use (c)hanged version, (d)elete, or leave (u)nresolved? u
  [1]
  $ [ -f file1 ] || echo "File does not exist?"
  $ hg resolve --list
  U file1
  $ rm file1
  $ hg resolve --mark --config commands.resolve.mark-check=abort
  (no more unresolved files)
  $ hg resolve --list
  R file1
  $ hg resolve --unmark file1
  $ hg resolve file1
  file 'file1' was deleted in other [merge rev] but was modified in local [working copy].
  What do you want to do?
  use (c)hanged version, (d)elete, or leave (u)nresolved? u
  [1]
  $ [ -f file1 ] || echo "File does not exist?"
  $ hg resolve --list
  U file1
  $ rm file1
  $ hg resolve --mark --config commands.resolve.mark-check=warn

  $ hg resolve --list
  R file1
