  CONTRIBUTING.rst: Correcting `Context` example in the "imports" section
  
  This example is very outdated and comes from pre 1.0 when the Context
  object was going to be public API. Just corrected the example made about
  imports to import the `Context` object from `._context` instead of `.context`.

  CONTRIBUTING.rst: Added section in PEP-8 coding style about line lengths.
  
  We have a long line limit in order to handle the exceptions without making
  code unreadable as a result, this long line length limit is not an invitation
  to fill up the limit as much as possible.

  bst-docker-import: Consistently use stderr for all logs
  
  In !857, we added `contrib/bst-docker-import` script but it has a small
  issue that some of logs go to stdout while others go to stderr. Fix it
  so that all logging is done on stderr.

  doc: Add new document about Docker integrations
  
  Add a new section under "Additional writings" section about how
  BuildStream integrates with Docker. At present, this section includes
  only two sections:
  
  - "Run BuildStream inside Docker", that refers to existing instructions
  for doing so
  - "Generate Docker images", that adds instructions for using the newly
  added `contrib/bst-docker-import` script
  
  In future, this document can be extended to include the following
  things:
  
  - Importing Docker sources via `docker` source plugin - if/when the
  Docker source plguin is moved from bst-external to BuildStream proper
  - A Docker sandbox, if/when that is added

  Sandbox: CWD was not being created for workspaces
  
  The code was creating the cwd folder but when the workspace was
  mounted in to the buildroot it was hiding the folder created in it
  behind the bind mounted workspace.
  
  However by using the bubblewarp `--dir` directive to ensure that cwd
  exists we can cover both workspace and non workspace situations with
  the same method.
  
  For issue #512 in Gitlab.

  source.py: Quiet several pylint issues with abstract methods
  
  A number of times, abstract methods are called which pylint cannot
  possibly understand will only ever happen in subclasses which implement
  the abstract methods.  This silences those specific warnings

  utils.py: Disable lint warning about popen
  
  We use `preexec_fn` in our use of Popen.  Since there are threads
  in the codebase, this is not necessarily safe.  However we go to
  great lengths to ensure that the main process doesn't spawn threads
  (they're used in gRPC a lot) and so it should be safe for our use.
  As such, we disable the lint here.

  Check if command is a str and replace by list before checking existence
  
  Currently we would make sure the sandbox had a command before
  converting it to a list if it was given as a string. That meant that a string
  command would never exist and the check be invalid.
  
  This also adds the same logic in the dummy sandbox for consistency.

  element.py: Always clean up the rootdir
  
  We shouldn't need it to persist now that we cache failed build dirs.
  
  This change breaks the test
  `tests/integration/shell.py::test_sysroot_workspace_visible`.
  I can no longer see a use-case for this test.
  AIUI, it tested that the failed build sysroot stored in the builddir has
  the workspace's files in, despite the workspace being unmounted.
  I believe this behaviour is made redundant by cached buildtrees.

  This includes changes in app.py:

  Changes in element.py are:
  * Errors caused by building don't store the failed build sysroot,
    instead storing that a sandbox can be created to debug the error.
  * When staging sources, will stage the element's cached build tree if it
    exists.
  
  Changes in _exceptions.py:
  * BstError.sandbox is now a flag of whether a sandbox can be opened up
    to debug the error.
  
  Changes in widget.py:
  * Don't try to print any information about the sandbox.

  This includes a new command mimicking pytest-runner so that we
  can drop this dependency
  
  This was the only setup_requires dependency that we had and
  will make like easier for people behind proxies

  BREAK: manual.yaml: don't set any default env vars
  
  Remove the 'MAKEFLAGS' and 'V' defaults.
  
  Now that there is a specialised 'make' element, these make-specific
  defaults don't make sense here. This element is meant to be a blank
  slate for folks to build on.
  
  Note that this is a breaking change, that will require some users to
  make changes to their .bst files if they are expecting these environment
  variable to be set.
  
  _versions.py: BST_FORMAT_VERSION bumped to 18.
  
  This fixes issue #718

  _yaml.py: Implement `get()` for `ChainMap`
  
  Since the core Python `ChainMap.get()` implements with:
  
      self[key] if key in self else default
  
  The double-chain-lookup is expensive.  This simple change solves that
  for our ChainMap derived structure.  As such it improves matters
  for #466 somewhat.
