debugindex: rename the parent column to mention nodeid

We will add new columns with the "revnum" version of the parent. It will be
useful in case we need to inspect a corrupted revlog index.

Tests for experimental.removeemptydirs

  $ cat >> pwd.py << EOF
  > import os
  > try:
  >     print(os.getcwd())
  > except OSError:
  >     print("<directory is no longer accessible>")
  > EOF

  $ NO_RM=--config=experimental.removeemptydirs=0
  $ DO_RM=--config=experimental.removeemptydirs=1
  $ isdir() { if [ -d $1 ]; then echo yes; else echo no; fi }
  $ isfile() { if [ -f $1 ]; then echo yes; else echo no; fi }

`hg rm` of the last file in a directory:
  $ hg init hgrm
  $ cd hgrm
  $ mkdir somedir
  $ echo hi > somedir/foo
  $ hg ci -qAm foo
  $ isdir somedir
  yes
  $ hg rm somedir/foo
  $ isdir somedir
  no
  $ hg revert -qa
  $ isdir somedir
  yes
  $ hg $NO_RM rm somedir/foo
  $ isdir somedir
  yes
  $ ls somedir
  $ cd $TESTTMP

`hg mv` of the last file in a directory:
  $ hg init hgmv
  $ cd hgmv
  $ mkdir somedir
  $ mkdir destdir
  $ echo hi > somedir/foo
  $ hg ci -qAm foo
  $ isdir somedir
  yes
  $ hg mv somedir/foo destdir/foo
  $ isdir somedir
  no
  $ hg revert -qa
(revert doesn't get rid of destdir/foo?)
  $ rm destdir/foo
  $ isdir somedir
  yes
  $ hg $NO_RM mv somedir/foo destdir/foo
  $ isdir somedir
  yes
  $ ls somedir
  $ cd $TESTTMP

Updating to a commit that doesn't have the directory:
  $ hg init hgupdate
  $ cd hgupdate
  $ echo hi > r0
  $ hg ci -qAm r0
  $ mkdir somedir
  $ echo hi > somedir/foo
  $ hg ci -qAm r1
  $ isdir somedir
  yes
  $ hg co -q -r ".^"
  $ isdir somedir
  no
  $ hg co -q tip
  $ isdir somedir
  yes
  $ hg $NO_RM co -q -r ".^"
  $ isdir somedir
  yes
  $ ls somedir
  $ cd $TESTTMP

Rebasing across a commit that doesn't have the directory, from inside the
directory:
  $ hg init hgrebase
  $ cd hgrebase
  $ echo hi > r0
  $ hg ci -qAm r0
  $ mkdir somedir
  $ echo hi > somedir/foo
  $ hg ci -qAm first_rebase_source
  $ hg $NO_RM co -q -r ".^"
  $ echo hi > somedir/bar
  $ hg ci -qAm first_rebase_dest
  $ hg $NO_RM co -q -r ".^"
  $ echo hi > somedir/baz
  $ hg ci -qAm second_rebase_dest
  $ hg co -qr 'desc(first_rebase_source)'
  $ cd $TESTTMP/hgrebase/somedir
  $ hg --config extensions.rebase= rebase -qr . -d 'desc(first_rebase_dest)'
  current directory was removed (rmcwd !)
  (consider changing to repo root: $TESTTMP/hgrebase) (rmcwd !)
  $ cd $TESTTMP/hgrebase/somedir
(The current node is the rebased first_rebase_source on top of
first_rebase_dest)
This should not output anything about current directory being removed:
  $ hg $NO_RM --config extensions.rebase= rebase -qr . -d 'desc(second_rebase_dest)'
  $ cd $TESTTMP

Histediting across a commit that doesn't have the directory, from inside the
directory (reordering nodes):

A directory with the right pass exists at the end of the run, but it is a
different directory than the current one.

Windows is not affected

  $ hg init hghistedit
  $ cd hghistedit
  $ echo hi > r0
  $ hg ci -qAm r0
  $ echo hi > r1
  $ hg ci -qAm r1
  $ echo hi > r2
  $ hg ci -qAm r2
  $ mkdir somedir
  $ echo hi > somedir/foo
  $ hg ci -qAm migrating_revision
  $ cat > histedit_commands <<EOF
  > pick 89079fab8aee 0 r0
  > pick e6d271df3142 1 r1
  > pick 89e25aa83f0f 3 migrating_revision
  > pick b550aa12d873 2 r2
  > EOF
  $ cd $TESTTMP/hghistedit/somedir
  $ hg $DO_RM --config extensions.histedit= histedit -q --commands ../histedit_commands
  current directory was removed (no-windows !)
  (consider changing to repo root: $TESTTMP/hghistedit) (no-windows !)
  $ ls -1 $TESTTMP/hghistedit/
  histedit_commands
  r0
  r1
  r2
  somedir
#if windows
  $ "$PYTHON" "$TESTTMP/pwd.py"
  $TESTTMP/hghistedit/somedir
#else
  $ echo ${PWD} # no-pwd-check
  $TESTTMP/hghistedit/somedir
  $ "$PYTHON" "$TESTTMP/pwd.py"
  <directory is no longer accessible>
#endif
  $ ls -1 $TESTTMP/hghistedit/somedir
  foo
  $ ls -1
  foo (windows !)

Get out of the doomed directory

  $ cd $TESTTMP/hghistedit
  chdir: error retrieving current directory: getcwd: cannot access parent directories: $ENOENT$ (?)
  $ hg files --rev . | grep somedir/
  somedir/foo


  $ cat > histedit_commands <<EOF
  > pick 89079fab8aee 0 r0
  > pick 7c7a22c6009f 3 migrating_revision
  > pick e6d271df3142 1 r1
  > pick 40a53c2d4276 2 r2
  > EOF
  $ cd $TESTTMP/hghistedit/somedir
  $ hg $NO_RM --config extensions.histedit= histedit -q --commands ../histedit_commands
Regardless of system, we should always get a 'yes' here.
  $ isfile foo
  yes
  $ cd $TESTTMP

This is essentially the exact test from issue5826, just cleaned up a little:

  $ hg init issue5826_withrm
  $ cd issue5826_withrm

Let's only turn this on for this repo so that we don't contaminate later tests.
  $ cat >> .hg/hgrc <<EOF
  > [extensions]
  > histedit =
  > EOF
Commit three revisions that each create a directory:

  $ mkdir foo
  $ touch foo/bar
  $ hg commit -qAm "add foo"

  $ mkdir bar
  $ touch bar/bar
  $ hg commit -qAm "add bar"

  $ mkdir baz
  $ touch baz/bar
  $ hg commit -qAm "add baz"

Enter the first directory:

  $ cd foo

Histedit doing 'pick, pick, fold':

#if rmcwd

  $ hg histedit --commands - <<EOF
  > pick 6274c77c93c3 1 add bar
  > pick ff70a87b588f 0 add foo
  > fold 9992bb0ac0db 2 add baz
  > EOF
  current directory was removed
  (consider changing to repo root: $TESTTMP/issue5826_withrm)
  abort: $ENOENT$
  [255]

Go back to the repo root after losing it as part of that operation:
  $ cd $TESTTMP/issue5826_withrm

Note the lack of a non-zero exit code from this function - it exits
successfully, but doesn't really do anything.
  $ hg histedit --continue

  $ cd $TESTTMP/issue5826_withrm

  $ hg histedit --commands - <<EOF

  1:b9eddaa97cbc add foo

  add baz
  0:d17db4b0303a add bar

#endif

Now test that again with experimental.removeemptydirs=false:
  $ hg init issue5826_norm
  $ cd issue5826_norm

Let's only turn this on for this repo so that we don't contaminate later tests.
  $ cat >> .hg/hgrc <<EOF
