  element.py: Do not include type name of artifact cache in cache key
  
  The artifact cache backend does not affect build outputs and we anyway
  no longer have pluggable artifact cache backends. This hardcodes
  CASCache instead of removing the entry completely to avoid cache key
  changes.

  by Jürg Billeter at 2018-11-05T17:18:12Z

  Split up artifact cache and CAS cache
  
  This changes CASCache from a subclass to a delegate object of
  ArtifactCache. As the lower layer, CASCache no longer deals with
  elements or projects.
  
  Fixes #659.

  Fix cache corruption by scripts when layout and integration commands are used
  
  Root directory was marked as a non-artifact mount, so not using
  SafeHardLink.  However integration commands executed with write access
  to the root directory.

  Move bwrap checks in platform/linux.py
  
  Remove the bwraps checks from _site.py and put them in platform.linux
  which is the only place where they are run.
  
  This allows the removal of a double level of caching, making
  reasoning about tests easier

  conftest.py: Ensure platform is not maintained between tests
  
  This removes the `_instance` on the platform object that we use
  for caching and not recreating the object everytime at the start
  of every test.
  
  This is to ensure our tests share the least amount of state.
  
  The performance penalty is from 5 to 10% accross the whole test suite.
  The readings were done 5 times for each before and after the change
  and on the same computer.

  Test that helpful messages are raised when missing dependencies
  
  This adds a `reason` to the SandboxEror thrown in sandboxdummy
  to be able to understand where the error comes from

  contributing: WIP again to be kind to reviewers
  
  As someone coming from GitHub to GitLab, I was pleasantly surprised by
  the 'filter by WIP status' option.
  
  To make sure we get the most out of it, add a guideline to keep the
  filter clean, to reduce reviewer burden.

  contributing: non-WIP should always be landable
  
  I was recently surprised that we don't prefer addressing review comments
  in 'fixup!' commits.
  
  Coming from GitHub, I've found that fixup commits make it easier for
  reviewers to see what has changed since their last review. The idea is
  to use '--autosquash' before landing to clean up the history again.
  
  It's a pleasant surprise that it's easy to keep track of what changed in
  merge-requests between pushes, so we can always keep the history clean.
  
  Document this, so folks like me can see the light sooner.

  contributing: emphasise the 'why' in commits
  
  Explain why it's useful to mention the decisions made for a change and
  provide links for background, e.g. issue numbers.
  
  My general experience of git histories is that folks don't do enough
  explaining, so it's great we have a contributing section for it.
  
  I've found it's easier for folks to stick to rules when they know the
  practical reasons for them, so provide some.

  cli: Interactively warn if the user is trying to close the workspace they're using to load the project
  
  This involves changes in:
  * _stream.py:
    * Add the helper Stream.workspace_is_required()
  * cli.py:
    * If buildstream is invoked interactively, prompt the user to confirm
      that they want to close the workspace they're using to load this
      project.
