automation: delete code related to Python 2.7 support The building of Inno and WiX installers took a python_version argument that allowed us to specify "2" or "3" for the major Python version. Since we no longer support Python 2, we can delete this argument and everything feeding into it. Differential Revision: https://phab.mercurial-scm.org/D12264

#require rhg

  $ NO_FALLBACK="env RHG_ON_UNSUPPORTED=abort"

Rhg works well when sparse working copy is enabled.

  $ cd "$TESTTMP"
  $ hg init repo-sparse
  $ cd repo-sparse
  $ cat > .hg/hgrc <<EOF
  > [extensions]
  > sparse=
  > EOF

  $ echo a > show
  $ echo x > hide
  $ mkdir dir1 dir2
  $ echo x > dir1/x
  $ echo y > dir1/y
  $ echo z > dir2/z

  $ hg ci -Aqm 'initial'
  $ hg debugsparse --include 'show'
  $ ls -A
  .hg
  show

  $ tip=$(hg log -r . --template '{node}')
  $ $NO_FALLBACK rhg files -r "$tip"
  dir1/x
  dir1/y
  dir2/z
  hide
  show
  $ $NO_FALLBACK rhg files
  show

  $ $NO_FALLBACK rhg cat -r "$tip" hide
  x

  $ cd ..

We support most things when narrow is enabled, too, with a couple of caveats.

  $ . "$TESTDIR/narrow-library.sh"
  $ real_hg=$RHG_FALLBACK_EXECUTABLE

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > narrow=
  > EOF

  [1]

A naive implementation of [rhg files] leaks the paths that are supposed to be
hidden by narrow, so we just fall back to hg.

  $ $NO_FALLBACK rhg files -r "$tip"
  unsupported feature: rhg files -r <rev> is not supported in narrow clones
  [252]
  $ "$real_hg" files -r "$tip"
  dir1/x
  dir1/y

Hg status needs to do some filtering based on narrow spec, so we don't
support it in rhg for narrow clones yet.

  $ mkdir dir2
  $ touch dir2/q
  $ "$real_hg" status
  $ $NO_FALLBACK rhg --config rhg.status=true status
  unsupported feature: rhg status is not supported for sparse checkouts or narrow clones yet

Adding "orphaned" index files:

  $ (cd ..; cp repo-sparse/.hg/store/data/hide.i repo-narrow/.hg/store/data/hide.i)
  $ (cd ..; mkdir repo-narrow/.hg/store/data/dir2; cp repo-sparse/.hg/store/data/dir2/z.i repo-narrow/.hg/store/data/dir2/z.i)
  $ "$real_hg" verify

  crosschecking files in changesets and manifests
  checking files
  checked 1 changesets with 2 changes to 2 files

  $ "$real_hg" files -r "$tip"
  dir1/x
  dir1/y

# TODO: even though [hg files] hides the orphaned dir2/z, [hg cat] still shows it.
# rhg has the same issue, but at least it's not specific to rhg.
# This is despite [hg verify] succeeding above.

  $ $NO_FALLBACK rhg cat -r "$tip" dir2/z
  z
  $ "$real_hg" cat -r "$tip" dir2/z
  z
