ci: add a runner for macos

This is running from a venv, created with the packages from the requirements
file in the `test-setup-future-work` topic being discussed separately.  We can
basically reuse the existing `test_c` configuration as-is, but there was one
small issue- if the clone from the previous CI run is still present in `/tmp`,
the clone for the current run fails.  It's not a problem for the current setup
because a new container is instantiated, so the easy fix is to simply delete the
clone first.  (The Windows CI avoids this by not cloning in the first place.)

It looks like it takes ~80m to run the whole test suite on the current system.

===============================
Test the "tracked hint" feature
===============================

The tracked hint feature provide a file that get updated when the set of tracked
files get updated.

basic setup

  $ cat << EOF >> $HGRCPATH
  > [format]
  > use-dirstate-tracked-hint=yes
  > EOF

  $ hg init tracked-hint-test
  $ cd tracked-hint-test
  $ hg debugbuilddag '.+10' -n
  $ hg log -G -T '{rev} {desc} {files}\n'
  o  10 r10 nf10

  o  9 r9 nf9

  o  8 r8 nf8

  o  7 r7 nf7

  o  6 r6 nf6

  o  5 r5 nf5

  $ hg up tip

  $ hg files

key-file exists
-----------

The tracked hint file should exist

  $ ls -1 .hg/dirstate*
  .hg/dirstate
  .hg/dirstate-tracked-hint

key-file stay the same if the tracked set is unchanged
------------------------------------------------------

(copy its content for later comparison)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ echo foo >> nf0
  $ sleep 1
  $ hg status
  M nf0
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  $ hg revert -C nf0
  $ sleep 1
  $ hg status
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck

key-file change if the tracked set is changed manually
------------------------------------------------------

adding a file to tracking

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ echo x > x
  $ hg add x
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

remove a file from tracking
(forget)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg forget x
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

(remove)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg remove nf1
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

key-file changes on revert (when applicable)
--------------------------------------------

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status
  R nf1
  ? x
  $ hg revert --all
  undeleting nf1
  $ hg status
  ? x
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]


`hg update` does affect the key-file (when needed)
--------------------------------------------------

update changing the tracked set

(removing)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status --rev . --rev '.#generations[-1]'
  R nf10
  $ hg up '.#generations[-1]'
  0 files updated, 0 files merged, 1 files removed, 0 files unresolved
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

(adding)

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status --rev . --rev '.#generations[1]'
  A nf10
  $ hg up '.#generations[1]'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck
  Files .hg/dirstate-tracked-hint and ../key-bck differ
  [1]

update not affecting the tracked set

  $ echo foo >> nf0
  $ hg commit -m foo

  $ cp .hg/dirstate-tracked-hint ../key-bck
  $ hg status --rev . --rev '.#generations[-1]'
  M nf0
  $ hg up '.#generations[-1]'
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ diff --brief .hg/dirstate-tracked-hint ../key-bck

Test upgrade and downgrade
==========================

  $ test -f .hg/dirstate-tracked-hint
  $ hg debugrequires | grep 'tracked'
  dirstate-tracked-key-v1

downgrade

  $ hg debugupgraderepo --config format.use-dirstate-tracked-hint=no --run --quiet
  upgrade will perform the following actions:
  
  requirements
     preserved: * (glob)
     removed: dirstate-tracked-key-v1
  
  no revlogs to process
  
  $ test -f .hg/dirstate-tracked-hint
  [1]
  $ hg debugrequires | grep 'tracked'
  [1]

upgrade

  $ hg debugupgraderepo --config format.use-dirstate-tracked-hint=yes --run --quiet
  upgrade will perform the following actions:
  
  requirements
     preserved: * (glob)
     added: dirstate-tracked-key-v1
  
  no revlogs to process
  
  $ test -f .hg/dirstate-tracked-hint
  $ hg debugrequires | grep 'tracked'
  dirstate-tracked-key-v1
  $ cd ..

Test automatic upgrade and downgrade
------------------------------------

create an initial repository

  $ hg init auto-upgrade \
  > --config format.use-dirstate-tracked-hint=no
  $ hg debugbuilddag -R auto-upgrade --new-file .+5
  $ hg -R auto-upgrade update
  6 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg debugformat -R auto-upgrade | grep tracked
  tracked-hint:        no

upgrade it to dirstate-tracked-hint automatically

  $ hg status -R auto-upgrade \
  > --config format.use-dirstate-tracked-hint.automatic-upgrade-of-mismatching-repositories=yes \
  > --config format.use-dirstate-tracked-hint=yes
  automatically upgrading repository to the `tracked-hint` feature
  (see `hg help config.format.use-dirstate-tracked-hint` for details)
  $ hg debugformat -R auto-upgrade | grep tracked
  tracked-hint:       yes

rhg supports this feature

  $ hg status -R auto-upgrade \
  > --config format.use-dirstate-tracked-hint=yes --config rhg.on-unsupported=abort

downgrade it from dirstate-tracked-hint automatically

  $ hg status -R auto-upgrade \
  > --config format.use-dirstate-tracked-hint.automatic-upgrade-of-mismatching-repositories=yes \
  > --config format.use-dirstate-tracked-hint=no
  automatically downgrading repository from the `tracked-hint` feature
  (see `hg help config.format.use-dirstate-tracked-hint` for details)
  $ hg debugformat -R auto-upgrade | grep tracked
  tracked-hint:        no
