tests: stabilize test-shelve.t#phasebased for #no-symlink and #no-execbit

The rev number ended up being 11 instead of 13 on Windows.  If I ever get back
to issue2020, this will go away.

shelve has a help message
  $ hg shelve -h
  hg shelve [OPTION]... [FILE]...
  
  save and set aside changes from the working directory
  
      Shelving takes files that "hg status" reports as not clean, saves the
      modifications to a bundle (a shelved change), and reverts the files so
      that their state in the working directory becomes clean.
  
      To restore these changes to the working directory, using "hg unshelve";
      this will work even if you switch to a different commit.
  
      When no files are specified, "hg shelve" saves all not-clean files. If
      specific files or directories are named, only changes to those files are
      shelved.
  
      In bare shelve (when no files are specified, without interactive, include
      and exclude option), shelving remembers information if the working
      directory was on newly created branch, in other words working directory
      was on different branch than its first parent. In this situation
      unshelving restores branch information to the working directory.
  
      Each shelved change has a name that makes it easier to find later. The
      name of a shelved change defaults to being based on the active bookmark,
      or if there is no active bookmark, the current named branch.  To specify a
      different name, use "--name".
  
      To see a list of existing shelved changes, use the "--list" option. For
      each shelved change, this will print its name, age, and description; use "
      --patch" or "--stat" for more details.
  
      To delete specific shelved changes, use "--delete". To delete all shelved
      changes, use "--cleanup".
  
  (use 'hg help -e shelve' to show help for the shelve extension)
  
  options ([+] can be repeated):
  
   -A --addremove           mark new/missing files as added/removed before
                            shelving
   -u --unknown             store unknown files in the shelve
      --cleanup             delete all shelved changes
      --date DATE           shelve with the specified commit date
   -d --delete              delete the named shelved change(s)
   -e --edit                invoke editor on commit messages
   -l --list                list current shelves
   -m --message TEXT        use text as shelve message
   -n --name NAME           use the given name for the shelved commit
   -p --patch               output patches for changes (provide the names of the
                            shelved changes as positional arguments)
   -i --interactive         interactive mode, only works while creating a shelve
      --stat                output diffstat-style summary of changes (provide
                            the names of the shelved changes as positional
                            arguments)
   -I --include PATTERN [+] include names matching the given patterns
   -X --exclude PATTERN [+] exclude names matching the given patterns
      --mq                  operate on patch repository
  
  (some details hidden, use --verbose to show complete help)

shelving in an empty repo should be possible
(this tests also that editor is not invoked, if '--edit' is not
specified)

  $ HGEDITOR=cat hg shelve
  shelved as default
  0 files updated, 0 files merged, 5 files removed, 0 files unresolved

  $ hg unshelve
  unshelving change 'default'

  $ hg commit -q -m 'initial commit'

  $ hg shelve
  nothing changed
  [1]

make sure shelve files were backed up

  $ ls .hg/shelve-backup
  default.hg
  default.patch
  default.shelve

checks to make sure we dont create a directory or
hidden file while choosing a new shelve name

when we are given a name

  $ hg shelve -n foo/bar
  abort: shelved change names can not contain slashes
  [255]
  $ hg shelve -n .baz
  abort: shelved change names can not start with '.'
  [255]
  $ hg shelve -n foo\\bar
  abort: shelved change names can not contain slashes
  [255]

when shelve has to choose itself

  $ hg branch x/y -q
  $ hg commit -q -m "Branch commit 0"
  $ hg shelve
  nothing changed
  [1]
  $ hg branch .x -q
  $ hg commit -q -m "Branch commit 1"
  $ hg shelve
  nothing changed
  [1]
  $ hg branch x\\y -q
  $ hg commit -q -m "Branch commit 2"
  $ hg shelve
  nothing changed
  [1]

cleaning the branches made for name checking tests

  $ hg up default -q
  $ hg strip e9177275307e+6a6d231f43d+882bae7c62c2 -q

create an mq patch - shelving should work fine with a patch applied

  $ echo n > n
  $ hg add n
  $ hg commit n -m second
  $ hg qnew second.patch

shelve a change that we will delete later

  $ echo a >> a/a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved

set up some more complex changes to shelve

  $ echo a >> a/a
  $ hg mv b b.rename
  moving b/b to b.rename/b
  $ hg cp c c.copy
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy

  R b/b

the common case - no options or filenames

  $ hg shelve
  shelved as default-01
  2 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ hg status -C

ensure that our shelved changes exist

  $ hg shelve -l

  temporarily committing pending changes (restore with 'hg unshelve --abort')
  rebasing shelved changes
  merging a/a

  $ hg revert --all -q
  $ rm a/a.orig b.rename/b c.copy

apply it and make sure our state is as expected

(this also tests that same timestamp prevents backups from being
removed, even though there are more than 'maxbackups' backups)

  $ f -t .hg/shelve-backup/default.patch
  .hg/shelve-backup/default.patch: file
  $ touch -t 200001010000 .hg/shelve-backup/default.patch

(both of default.hg and default-1.hg should be still kept, because it
is difficult to decide actual order of them from same timestamp)

  $ hg unshelve foo

named shelves, specific filenames, and "commit messages" should all work
(this tests also that editor is invoked, if '--edit' is specified)

  $ hg status -C

  HG: Leave message empty to abort commit.
  HG: --
  HG: user: shelve@localhost
  HG: branch 'default'

expect "a" to no longer be present, but status otherwise unchanged

  $ hg status -C
  A b.rename/b
    b/b
  A c.copy
    c
  R b/b
  $ hg shelve -l --stat
  wibble          (*)    wat (glob)
   a/a |  1 +
   1 files changed, 1 insertions(+), 0 deletions(-)

and now "a/a" should reappear

  $ cd a
  $ hg unshelve -q wibble
  $ cd ..
  $ hg status -C
  M a/a
  A b.rename/b
    b/b
  A c.copy

ensure old shelve backups are being deleted automatically

  $ ls .hg/shelve-backup/
  default-01.hg
  default-01.patch
  default-01.shelve
  wibble.hg
  wibble.patch
  wibble.shelve

  $ echo c>>a/a
  $ hg commit -m second
  $ hg tip --template '{files}\n'

"hg unshelve" at REV5 implies steps below:

(1) commit changes in the working directory (REV6)
(2) unbundle shelved revision (REV7)
(3) rebase: merge REV7 into REV6 (REV6 => REV6, REV7)
(4) rebase: commit merged revision (REV8)
(5) rebase: update to REV6 (REV8 => REV6)
(6) update to REV5 (REV6 => REV5)
(7) abort transaction

Shelve and unshelve unknown files. For the purposes of unshelve, a shelved
unknown file is the same as a shelved added file, except that it will be in
unknown state after unshelve if and only if it was either absent or unknown
before the unshelve operation.

  $ hg init unknowns
  $ cd unknowns

The simplest case is if I simply have an unknown file that I shelve and unshelve

  $ echo unknown > unknown
  $ hg status
  ? unknown
  $ hg shelve --unknown
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ hg unshelve
  unshelving change 'default'
  $ hg status
  ? unknown
  $ rm unknown

If I shelve, add the file, and unshelve, does it stay added?

  $ echo unknown > unknown
  $ hg shelve -u
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ touch unknown
  $ hg add unknown
  $ hg status
  A unknown
  $ hg unshelve
  unshelving change 'default'
  temporarily committing pending changes (restore with 'hg unshelve --abort')
  rebasing shelved changes
  merging unknown
  $ hg status
  A unknown
  $ hg forget unknown
  $ rm unknown

And if I shelve, commit, then unshelve, does it become modified?

  $ echo unknown > unknown
  $ hg shelve -u
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg status
  $ touch unknown
  $ hg add unknown
  $ hg commit -qm "Add unknown"
  $ hg status
  $ hg unshelve
  unshelving change 'default'
  rebasing shelved changes
  merging unknown
  $ hg status
  M unknown
  $ hg remove --force unknown
  $ hg commit -qm "Remove unknown"

  $ cd ..

We expects that non-bare shelve keeps newly created branch in
working directory.

  $ hg init shelve-preserve-new-branch
  $ cd shelve-preserve-new-branch
  $ echo "a" >> a
  $ hg add a
  $ echo "b" >> b
  $ hg add b
  $ hg commit -m "ab"
  $ echo "aa" >> a
  $ echo "bb" >> b
  $ hg branch new-branch
  marked working directory as branch new-branch
  (branches are permanent and global, did you want a bookmark?)
  $ hg status
  M a
  M b
  $ hg branch
  new-branch
  $ hg shelve a
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch

  $ hg status

  $ touch "c" >> c
  $ hg add c
  $ hg status

  $ hg shelve --exclude c

  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch

  $ hg shelve --include c
  shelved as default-02
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch
  new-branch
  $ hg status
  $ echo "d" >> d
  $ hg add d
  $ hg status
  A d

We expect that bare-shelve will not keep branch in current working directory.

  $ hg shelve
  shelved as default-03
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg branch
  default
  $ cd ..

When i shelve commit on newly created branch i expect
that after unshelve newly created branch will be preserved.

  $ hg init shelve_on_new_branch_simple
  $ cd shelve_on_new_branch_simple
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch

  $ hg branch test

  (branches are permanent and global, did you want a bookmark?)
  $ echo "bbb" >> a
  $ hg status

  $ hg shelve

  $ hg branch

  $ hg unshelve
  unshelving change 'default'

  $ hg status

When i shelve commit on newly created branch, make
some changes, unshelve it and running into merge
conflicts i expect that after fixing them and
running unshelve --continue newly created branch
will be preserved.

  test
  $ hg commit -m "test-commit"

When i shelve on test branch, update to default branch
and unshelve i expect that it will not preserve previous
test branch.

  $ echo "xxx" > b
  $ hg add b
  $ hg shelve
  shelved as test
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ hg update -r 7049e48789d7
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg unshelve
  unshelving change 'test'
  rebasing shelved changes
  $ hg status
  A b
  $ hg branch
  default
  $ cd ..

When i unshelve resulting in merge conflicts and makes saved
file shelvedstate looks like in previous versions in
mercurial(without restore branch information in 7th line) i
expect that after resolving conflicts and successfully
running 'shelve --continue' the branch information won't be
restored and branch will be unchanged.

shelve on new branch, conflict with previous shelvedstate

  $ hg init conflict
  $ cd conflict
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch
  default
  $ hg branch test
  marked working directory as branch test
  (branches are permanent and global, did you want a bookmark?)
  $ echo "bbb" >> a
  $ hg status
  M a
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  default
  $ echo "ccc" >> a
  $ hg status
  M a
  $ hg unshelve
  unshelving change 'default'
  temporarily committing pending changes (restore with 'hg unshelve --abort')
  rebasing shelved changes
  merging a
  warning: conflicts while merging a! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see 'hg resolve', then 'hg unshelve --continue')
  [1]

Removing restore branch information from shelvedstate file(making it looks like
in previous versions) and running unshelve --continue

  $ cp .hg/shelvedstate .hg/shelvedstate_old
  $ cat .hg/shelvedstate_old | grep -v 'branchtorestore' > .hg/shelvedstate

  $ echo "aaabbbccc" > a
  $ rm a.orig
  $ hg resolve --mark a
  (no more unresolved files)
  continue: hg unshelve --continue
  $ hg unshelve --continue
  unshelve of 'default' complete
  $ cat a
  aaabbbccc
  $ hg status
  M a
  $ hg branch
  default
  $ cd ..

On non bare shelve the branch information shouldn't be restored

  $ hg init bare_shelve_on_new_branch
  $ cd bare_shelve_on_new_branch
  $ echo "aaa" >> a
  $ hg commit -A -m "a"
  adding a
  $ hg branch
  default
  $ hg branch test
  marked working directory as branch test
  (branches are permanent and global, did you want a bookmark?)
  $ echo "bbb" >> a
  $ hg status
  M a
  $ hg shelve a
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg branch
  test
  $ hg branch default
  marked working directory as branch default
  (branches are permanent and global, did you want a bookmark?)
  $ echo "bbb" >> b
  $ hg status
  ? b
  $ hg unshelve
  unshelving change 'default'
  $ hg status
  M a
  ? b
  $ hg branch
  default
  $ cd ..

Prepare unshelve with a corrupted shelvedstate
  $ hg init r1 && cd r1
  $ echo text1 > file && hg add file
  $ hg shelve
  shelved as default
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ echo text2 > file && hg ci -Am text1
  adding file
  $ hg unshelve
  unshelving change 'default'
  rebasing shelved changes
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see 'hg resolve', then 'hg unshelve --continue')

  $ echo somethingsomething > .hg/shelvedstate

Unshelve --continue fails with appropriate message if shelvedstate is corrupted
  $ hg unshelve --continue
  abort: corrupted shelved state file
  (please run hg unshelve --abort to abort unshelve operation)
  [255]

Unshelve --abort works with a corrupted shelvedstate
  $ hg unshelve --abort
  could not read shelved state file, your working copy may be in an unexpected state
  please update to some commit

Unshelve --abort fails with appropriate message if there's no unshelve in
progress
  $ hg unshelve --abort
  abort: no unshelve in progress

  $ cd ..

Unshelve respects --keep even if user intervention is needed
  $ hg init unshelvekeep && cd unshelvekeep
  $ echo 1 > file && hg ci -Am 1
  adding file
  $ echo 2 >> file
  $ hg shelve
  shelved as default
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ echo 3 >> file && hg ci -Am 13
  $ hg shelve --list
  default         (*s ago) * changes to: 1 (glob)
  $ hg unshelve --keep
  unshelving change 'default'

  continue: hg unshelve --continue
  $ hg unshelve --continue
  unshelve of 'default' complete
  $ hg shelve --list

Unshelving when there are deleted files does not crash (issue4176)
  $ hg init unshelve-deleted-file && cd unshelve-deleted-file
  $ echo a > a && echo b > b && hg ci -Am ab
  adding a
  adding b
  $ echo aa > a && hg shelve
  shelved as default

  $ hg unshelve
  unshelving change 'default'
  $ hg shelve

  $ rm a && echo b > b
  $ hg st
  ! a
  $ hg unshelve
  unshelving change 'default'
  abort: shelved change touches missing files
  (run hg status to see which files are missing)
  [255]
  $ hg st

  $ cd ..

New versions of Mercurial know how to read onld shelvedstate files
  $ hg init oldshelvedstate
  $ cd oldshelvedstate
  $ echo root > root && hg ci -Am root
