ci: drop the phabricator refresh step

Now that phabricator is no longer in us, we should avoid this useless step to
save time and simplify things.

#require pygit2 no-windows

Setup:
  $ GIT_AUTHOR_NAME='test'; export GIT_AUTHOR_NAME
  > GIT_AUTHOR_EMAIL='[e-mail]'; export GIT_AUTHOR_EMAIL
  > GIT_AUTHOR_DATE="2007-01-01 00:00:00 +0000"; export GIT_AUTHOR_DATE
  > GIT_COMMITTER_NAME="$GIT_AUTHOR_NAME"; export GIT_COMMITTER_NAME
  > GIT_COMMITTER_EMAIL="$GIT_AUTHOR_EMAIL"; export GIT_COMMITTER_EMAIL
  > GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"; export GIT_COMMITTER_DATE
  > HGUSER="test <[e-mail]>"; export HGUSER
  > count=10
  > gitcommit() {
  >    GIT_AUTHOR_DATE="2007-01-01 00:00:$count +0000";
  >    GIT_COMMITTER_DATE="$GIT_AUTHOR_DATE"
  >    git commit "$@" >/dev/null 2>/dev/null || echo "git commit error"
  >    count=`expr $count + 1`
  >  }
  $ git config --global init.defaultBranch master


  $ hg version -v --config extensions.git= | grep '^[E ]'
  Enabled extensions:
    git  internal  (pygit2 *) (glob)

Test auto-loading extension works:
  $ mkdir nogit
  $ cd nogit
  $ mkdir .hg
  $ echo git >> .hg/requires
  $ hg status
  abort: repository specified git format in .hg/requires but has no .git directory
  [255]
  $ git config --global init.defaultBranch master
  $ git init
  Initialized empty Git repository in $TESTTMP/nogit/.git/
This status invocation shows some hg gunk because we didn't use
`hg init --git`, which fixes up .git/info/exclude for us.
  $ hg status
  ? .hg/cache/git-commits.sqlite
  ? .hg/cache/git-commits.sqlite-shm
  ? .hg/cache/git-commits.sqlite-wal
  ? .hg/requires
  $ cd ..

Now globally enable extension for the rest of the test:
  $ cat <<EOF >> $HGRCPATH
  > [extensions]
  > git=
  > [git]
  > log-index-cache-miss = yes
  > EOF

Test some edge cases around a commitless repo first
  $ mkdir empty
  $ cd empty
  $ git init
  Initialized empty Git repository in $TESTTMP/empty/.git/
  $ hg init --git
  $ hg heads
  [1]
  $ hg tip
  changeset:   -1:000000000000
  tag:         tip
  user:        
  date:        Thu Jan 01 00:00:00 1970 +0000
  
  $ cd ..

Make a new repo with git:
  $ mkdir foo
  $ cd foo
  $ git init
  Initialized empty Git repository in $TESTTMP/foo/.git/
Ignore the .hg directory within git:
  $ echo .hg >> .git/info/exclude
  $ echo alpha > alpha
  $ git add alpha
  $ gitcommit -am 'Add alpha'
  $ echo beta > beta
  $ git add beta
  $ gitcommit -am 'Add beta'
  $ echo gamma > gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
   (?)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

Without creating the .hg, hg status fails:
  $ hg status
  abort: no repository found in '$TESTTMP/foo' (.hg not found)
  [10]
But if you run hg init --git, it works:
  $ hg init --git
  $ hg id --traceback
  heads mismatch, rebuilding dagcache
  3d9be8deba43 tip master
  $ hg status
  ? gamma
Log works too:
  $ hg log
  changeset:   1:3d9be8deba43
  bookmark:    master
  tag:         tip
  user:        test <[e-mail]>
  date:        Mon Jan 01 00:00:11 2007 +0000
  summary:     Add beta

  date:        Mon Jan 01 00:00:10 2007 +0000
  summary:     Add alpha
  


and bookmarks:
  $ hg bookmarks
   * master                    1:3d9be8deba43

diff even works transparently in both systems:
  $ echo blah >> alpha
  $ git diff
  diff --git a/alpha b/alpha
  index 4a58007..faed1b7 100644
  --- a/alpha
  +++ b/alpha
  @@ -1* +1,2 @@ (glob)

  +blah
  $ hg diff --git
  diff --git a/alpha b/alpha

  +++ b/alpha
  @@ -1,1 +1,2 @@
   alpha
  +blah

Remove a file, it shows as such:
  $ rm alpha
  $ hg status
  ! alpha
  ? gamma

Revert works:
  $ hg revert alpha --traceback
  $ hg status
  ? gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
   (?)
  	gamma
  
  nothing added to commit but untracked files present (use "git add" to track)

Add shows sanely in both:
  $ hg add gamma
  $ hg status
  A gamma
  $ hg files
  alpha
  beta
  gamma
  $ git ls-files
  alpha
  beta
  gamma
  $ git status

  Changes to be committed:
    (use "git restore --staged <file>..." to unstage) (?)
    (use "git reset HEAD <file>..." to unstage) (?)
   (?)
  	new file:   gamma
  

forget does what it should as well:
  $ hg forget gamma
  $ hg status
  ? gamma
  $ git status
  On branch master
  Untracked files:
    (use "git add <file>..." to include in what will be committed)
   (?)

  nothing added to commit but untracked files present (use "git add" to track)

clean up untracked file
  $ rm gamma

hg log FILE

  $ echo a >> alpha

  $ echo b >> beta
  $ hg ci -m 'more beta'
