  CONTRIBUTING.rst: Fix formatting of link to pip docs
  
  The link explaining python's requirements files was formatted
  incorrectly (missing underscore at the end). This resulted in the text
  being rendered literally, as opposed to being converted into a
  hyperlink.

  Move push and pull to the new artifact subcommand group
  
  This commit also ensures that if we try to use the 'old' commands,
  BuildStream will fail and instruct the user to use the new command.

  cli: Add artifact checkout subcommand
  
  'artifact checkout' has slightly different behaviour from 'checkout',
  that is, either '--directory' or '--tar' are now required options.
  This is a step towards allowing checkout to take multiple args.

  Mark 'old' checkout command as obsolete
  
  This commit marks 'bst checkout' as a 'hidden' command. If used,
  the user will be prompted to use the new 'bst artifact checkout'
  command.
  
  All tests which used 'bst checkout' have been modified to use
  the new artifact sub-command.
  
  This partially solves #822.

  man: Regenerate all of our man pages
  
  Due to an upstream click_man issue:
  https://github.com/click-contrib/click-man/issues/10
  generating the man pages with our current setup.py only generates
  a man page for bst-artifact-server, our first entry point.
  I then had to remove this entry point from setup.py and regenerate to
  obtain man pages for the commands in cli.py

  cli.py: Add an obsoletion note to our deprecated commands.
  
  Click 7.0 allows us to declare commands as 'hidden'.
  However, sphinx-click and click-man still generate these hidden
  commands in the documentation and man pages, respectively.
  
  This is a stop gap solution until the upstream issues (tracked in
  issues #879 and #881) have been addressed.

  tests/integration/pullbuildtrees.py: Fix the non-integration case.
  
  This test has one test case which is marked as an integration test,
  and the other is not an integration test, but was using the integration
  cli. The integration cli does not work correctly if not run in
  integration mode.
  
  This was causing an error locally in conftest.py when trying to
  create a tmpdir inside a nonexisting integration cache directory.

  tests: Migrated cache quota test into artifactcache/cache_size.py
  
  Instead of sitting mysteriously alone in internals/utils.py
  

• 9be31641
  by Tristan Van Berkom at 2019-01-23T13:57:53Z

  _artifactcache.py: Raise ArtifactError() when quota size exceeds disk space.
  
  This is not an error related to loading data, like a parse error
  in the quota specification is, but a problem raised by the artifact
  cache - this allows us to assert more specific machine readable
  errors in test cases (instead of checking the string in stderr, which
  this patch also fixes).
  
  This also removes a typo from the error message in the said error.
  
    * tests/artifactcache/cache_size.py
  
      Updated test case to expect the artifact error, which consequently
      changes the test case to properly assert a machine readable error
      instead of asserting text in the stderr (which is the real, secret
      motivation behind this patch).
  
    * tests/artifactcache/expiry.py: Reworked test_invalid_cache_quota()
  
      Now expect the artifact error for the tests which check configurations
      which create caches too large to fit on the disk.

  tests/frontend/track.py: test_track_error_cannot_write_file() fixup
  
  This tests how BuildStream reacts when it fails to write the tracking
  results to the element files or project.refs file, which is an operation
  that plugins do not play a part in.
  
  As such, removing the per repo kind parameterization from this test
  as multiple runs are redundant here.

  an element with an open workspace will not be fetched.

  _frontend/cli.py: Ignore junctions in default targets where appropriate
  
  Junctions cannot be built, pulled, or pushed. Specifying a junction on
  the command line for these commands will result in an error. However,
  junctions may be in the list of default targets, so they need to be
  ignored for build, pull, and push commands.

  _scheduler/resources.py: Dont error out in unregister_exclusive_interest()
  
  Don't require the interest to be registered, just discard any interest,
  this function just sets a bit in a mask, and is not intended to maintain
  a balance like the reserve() function is.

  _scheduler/scheduler.py: Run cache size exclusively at startup
  
  When running any session that has Queues which require Resource.CACHE,
  check if our loaded estimated size exceeds the quota, and if so;
  lock the Resource.CACHE resource exclusively right away and run
  an exclusive initial cache size job.
  
  This ensures we cleanup first before doing anything which might
  add to the cache at startup time, if deemed needed.
  
  This is a partial fix for issue #737

  _frontend/widget.py: Render core messages more like other messages
  
  In order to test when core activities occur by parsing the stderr
  in tests, we should make the messages conform more.
  
  At the same time, this restores alignment of columns in core
  messages with the element processing related messages.
  
  Also, _scheduler/scheduler.py is updated to make it's activity names
  conform to the (current) 5 character limit for the sake of alignment.
  
  The tests/frontend/logging.py test gets it's regexes updated for
  the log lines it checks for in stderr.

  utils.py: Add _get_volume_size()
  
  We can streamline this call to os.statvfs() in a few places.
  

• 9fd9fbb9
  by Tristan Van Berkom at 2019-01-24T18:02:08Z

  _artifactcache.py: Refactored to use utils._get_volume_size()
  
  This will benefit from a better UtilError being raised, and
  and turns the artifact cache's local function into a one liner.
  
  The loop which finds the first existing directory in the
  given path has been removed, being meaningless due to the
  call to os.makedirs() in ArtifactCache.__init__().
  
  The local function was renamed to _get_cache_volume_size() and
  no longer takes any arguments, which is more suitable for the
  function as it serves as a testing override surface for
  unittest.mock().
  
  The following test cases which use the function to override
  the ArtifactCache behavior have been updated to use the new
  overridable function name:
  
     tests/artifactcache/cache_size.py
     tests/artifactcache/expiry.py

  Also enhanced messaging about what was cleaned up so far when
  aborting a cleanup.

  _artifactcache.py: Don't require the quota to be available on disk.
  
  Instead only rely on the headroom to be enough to protect against
  out of space conditions. The headroom can become configurable as
  a separate step is required.
  
  The changes to achieve this are:
  
    * Rename ArtifactCache.has_quota_exceeded() to ArtifactCache.full().
  
    * ArtifactCache.full() now also reports True if the available
      space on the artifact cache volume is smaller than the headroom.
  
      This ensures jobs get triggered to cleanup the cache when
      reaching the end of the disk.
  
    * When loading the artifact quota, it is now only an error if
      the quota exceeds the overall disk space, not if it does not
      fit in the available space.
  
      It is still a warning if the quota does not fit in the
      available space on the artifact cache volume.
  
    * Updated scheduler.py and buildqueue.py for the API rename
  
    * tests: Updated the artifactcache/expiry.py test for its
      expectations in this regard.
  
      Added a new test to test an error when quota was specified to
      exceed total disk space, and adjusted the existing tests to
      expect a warning when the quota does not fit in the available
      space.
  
  This fixes issue #733 and #869.

  setup.py: Do not error out when man directory is empty/missing
  
  If the `man` directory is empty, then it won't be copied in the source
  distribution, and `list_man_pages()` will throw an exception when trying
  to list files in a non-existent directory. This prevents us from
  installing the BuildStream package when the man pages are not there.
  
  The most common use-case for this is when we want to re-generate the man
  pages but want to install the package before re-generating them.

  Fix crash when spawned job completes very fast
  
  Job can complete before we return from `Job.span()` to
  `Scheduler._spawn_job()`, so that `_active_jobs` would not yet contain
  the job.
  
  This would print a stack on the console and try to run a second time
  the job which can have unexpected effects.
  
  In order to reproduce the issue, in
  `buildstream/_scheduler/jobs/job.py`, in `Job.spawn`,
  add a call to `time.sleep()` right before call to
  `asyncio.get_child_watcher()`.
  
  This fixes issue #857.
