  Add Error to git and ostree sources configure
  
  Raise a error at configure time if the track and ref properties are
  not present in the sources.
  
  This is to address https://gitlab.com/BuildStream/buildstream/issues/471
  that documented unhelpful behaviour when tracking git sources. However
  the issue was also identified in ostree.

  setup.cfg: Add tests/integration/project to norecursedirs
  
  This is causing pytest to try to import the recently added app1.py
  from the pip related tests. This fails because it's not meant to be

  Use ArtifactCache's get_cache_size when calculating the quota
  
  It would have been more convenient to store the quota size in the
  ArtifactCache, except that the scheduler needs the quota size and
  doesn't have access to the ArtifactCache.

  Fix broken indentation after tracking.
  
  Issue was introduced by 171e803f (include directive) and the fix was
  found courtesy of @Qinusty. This fixes also the include
  feature. Because elements are to be serialized, the included fragments
  need to use copy_tree when loaded.
  
  Related to #470.

  dev-requirements.txt: Pin versions of pytest and pylint
  
  These packages should only be updated as a deliberate change and the
  code should be tested with the new versions to ensure that the test
  still pass.
  
  Any future updates should also happen in sync with the
  buildstream-docker-images repository so that the testsuite base images
  also enforce the same restrictions for the development requirements.

  _frontend/linuxapp.py: Fix special casing around desktop notification escape sequence
  
  Now we allow the notification to happen on any TERM
  which starts with 'xterm' or 'vte', and we only do it
  if the VTE_VERSION is >= 4600, where we know for sure that
  VTE will not print garbage on the terminal.

  Catch Non Numeric versions
  
  This patch just displays a better message than the default stack trace
  but dose not try to fix the problem. A further patch will be created but
  it effects versioneer so may take longer to land as it may need to go
  via versioneer mainline.

  Search for tags with the *.*.* patten for version
  
  This has been done in a way that I hope might be able to be upstreamed
  in to versioneer. This is not garanteed but it would be good if it
  could be.

  Don't strip pathname from debug symbol files
  
  When GDB looks for debug symbols it looks for the full path of the file
  inside the configured debug-file-directory. For example, if the
  debug-file-directory is set to a default of /usr/lib/debug, and you are
  debugging /usr/bin/python3, GDB will look for its debug symbols at this
  location: /usr/lib/debug/usr/bin/python3.
  
  BuildStream has been putting all debug files inside /usr/lib/debug
  under their $(basename), so in the above example GDB would fail to find
  any debug symbols for /usr/bin/python3 because they would be in the
  incorrect locatoin of /usr/lib/debug/python3.

  MANIFEST.in: Fix include for dev-requirements.txt
  
  Currently, running any setuptools commands using `setup.py` generates a
  warning like so:
          warning: manifest_maker: MANIFEST.in, line 21: unknown action 'dev-requirements.txt'
  
  The syntax is invalid and got accidentally introduced in !637 but it's a
  shame that this is not a warning and no obvious way to make it an error
  if there are invalid things in MANIFEST.in file.

  deps: Specify the minimum version required for blessings
  
  Buildstream uses the Terminal.does_styling attribute, which was only
  added in blessings 1.6.
  
  Blessings helpfully returns an empty string when calling an nonexistent
  attribute on the Terminal object, instead of failing.
  
  Because Fedora has blessings 1.5, Buildstream thought that my terminal
  couldn't handle styling, and just didn't print the status bar, silently.
  
  Specifying the minimum version avoids this silent failure.

  .gitlab-ci.yml: Verify that source tarball installs correctly
  
  Add a check to verify that the source distribution tarball that we
  generate installs corrctly. It is useful to do this check as this is the
  same tarball will be used when installing BuildStream via PyPI.
  
  This check also happens indirectly in the coverage job where we install
  BuildStream but this check makes it more explicit and will also cause
  the CI to fail early if the tarball is not correct.

  The Source must now mention whether the marked or translated
  URL is "primary" or not. Even when a Source may have multiple
  URLs, the auxilliary URLs are derived from the primary one, not
  only is this true for git, but it is mandated by our tracking
  API which assumes there is a primary URL.
  
  This adjusts the `git` source and the test `fetch_source.py` source
  to behave properly and advertize it's primary URL properly.

  which is used when staging & initing the source workspace. It
  checks the element's ref exists in the track (branch/tag) if it
  has been specified, raising a warning if necessary. The warning makes
  use of the warning token 'REF_NOT_IN_TRACK' from the configurable
  CoreWarnings. If the element has been tracked with bst, it is assumed
  that the value of ref exists in the track as it was generated from it
  & as such is not asserted.

  jobs.py: Reduce FD leaks from queues and process objects
  
  The garbage collector can take too long to get around to cleaning
  up the Queue and Process instances in completed Job instances.  As
  such, FDs tend to leak and in very large projects this can result
  in running out of FDs before a build, fetch, track, or other process
  can complete.  This patch reduces the chance of that by only creating
  the queue when it's needed, and forcing the queue and process instances
  to be deleted when the parent is finished with them.

  shared access.

    o ArtifactCache.set_cache_size()

  _scheduler: API fixes; _check_cache_size_real() -> check_cache_size()
  
  Here we have a very private looking _check_cache_size_real() function
  which no-one would ever want to call from outside of the _scheduler,
  especially given it's `_real()` prefix we should look for another
  outward facing API to use.
  
  However this is not private to the scheduler, and is intended to
  be called by the `Queue` implementations.
  
    o Renamed this to check_cache_size()
  
    o Moved it to the public API section of the Scheduler object
  
    o Added the missing API documenting comment
  
    o Also added the missing API documenting comment to the private
      `_run_cleanup()` callback which runs in response to completion
      of the cache size calculation job.
  
    o Also place the cleanup job logs into a cleanup subdirectory,
      for better symmetry with the cache_size jobs which now have
      their own subdirectory

  _artifactcache/artifactcache.py: Removing unused variable.
  
  The ArtifactCache._local variable used to exist in order to
  use a special hack to allow absolute paths to a remote artifact
  cache, this was all for the purpose of testing.
  
  This has all gone away with the introduction of CAS, leaving behind
  a stale variable.

  _artifactcache/artifactcache.py: Sealing away some the estimated size
  
  Previously, the API contract was to expose the estimated_size variable
  on the ArtifactCache instance for all to see, however it is only relevant
  to the ArtifactCache abstract class code. Subclasses were informed to
  update the estimated_size variable in their calculate_cache_size()
  implementation.
  
  To untangle this and hide away the estimated size, this commit
  does the following:
  
    o Introduces ArtifactCache.compute_cache_size() API for external
      callers
  
    o ArtifactCache.compute_cache_size() calls the abstract method
      for the CasCache subclass to implement
  
    o ArtifactCache.compute_cache_size() updates the private
      estimated_size variable
  
    o All direct callers to ArtifactCache.calculate_cache_size(),
      have been updated to use the ArtifactCache.compute_cache_size()
      method instead, which takes care of updating anything local
      to the ArtifactCache abstract class code (the estimated_size)

  the BuildQueue implementation where the value is observed.

  The artifact cache is anyway a singleton, the Element itself

  specific and should not be looked up by surrounding code

  and _scheduler/jobs/elementjob.py to get the artifact cache directly
  from the Platform

  _artifactcache: There shalt be only one cache size
  
  This does a lot of house cleaning, finally bringing cache
  cleanup logic to a level of comprehensibility.
  
  Changes in this commit include:
  
    o _artifactcache/artifactcache.py: _cache_size, _cache_quota and
      _cache_lower_threshold are now all private variables.
  
      get_approximate_cache_size() is now get_cache_size()
  
      Added get_quota_exceeded() for the purpose of safely checking
      if we have exceeded the quota.
  
      set_cache_size() now asserts that the passed size is not None,
      it is not acceptable to set a None size cache anymore.
  
    o _artifactcache/cascache.py: No longer set the ArtifactCache
      'cache_size' variable violently in the commit() method.
  
      Also the calculate_cache_size() method now unconditionally
      calculates the cache size, that is what it's for.
  
    o _scheduler/jobs/cachesizejob.py & _scheduler/jobs/cleanupjob.py:
  
      Now check the success status. Don't try to set the cache size
      in the case that the job was terminated.
  
    o _scheduler/jobs/elementjob.py & _scheduler/queues/queue.py:
  
      No longer passing around the cache size from child tasks,
      this happens only explicitly, not implicitly for all tasks.
  
    o _scheduler/queues/buildqueue.py & _scheduler/scheduler.py:
  
      Use get_quota_exceeded() accessor

  subprocesses: Ensure PWD is set in process environment
  
  Naive getcwd implementations (such as in bash 4.4) can break
  when bind-mounts to different paths on the same filesystem are present,
  since the algorithm needs to know whether it's a mount-point
  to know whether it can trust the inode value from the readdir result
  or to use stat on the directory.
  
  Less naive implementations (such as in glibc) iterate again using stat
  in the case of not finding the directory because the inode in readdir was wrong,
  though a Linux-specific implementation could use name_to_handle_at.
  
  Letting the command know what directory it is in makes it unnecessary
  for it to call the faulty getcwd in the first place.

  Tidy relative workspace tests
  
  They were moving the whole tmpdir to move the project repository.
  This moves the cache directories etc. as well, meaning cli.run can't find them.
  This was worked around by setting configure=False,
  but this has the side-effect of making use of the user's caches,
  which it should not be doing for reproducibility reasons.
  
  By changing the tempdir layout to have the project in a subdirectory
  we can move the project around for the relative workspace tests
  without losing track of the configured state directories,
  so we can leave configure=True and avoid touching the user's caches.

  _artifactcache/artifactcache.py: Ensure no double-setup of remotes
  
  Since ArtifactCache.setup_remotes() can be expensive and should only
  happen once, this commit will assert() if it is called a second time
  on an artifact cache instance.

  tests/artifactcache/pull.py: Do not double-initialize remotes
  
  The initialization of remotes is done by ArtifactCache.setup_remotes()
  and as such it was wrong for these tests to be calling
  CASCache.initialize_remotes() a second time.

  sandbox/_sandboxremote.py: Acquire artifact cache via Platform
  
  The SandboxRemote used to construct its own CASCache which was
  considered dangerous.  This patch replaces that with acquisition of
  the cache via the Platform singleton, hopefully eliminating issues
  from having more than one artifact cache object in a single process.

  _artifactcache/artifactcache.py: Error out gracefully when push remote is mal-specified

  fuse: Report the correct device number for devices
  
  This fixes all devices being mapped to the non-existant device 0,
  which prevents being able to use even safe devices like /dev/null
  through the hardlinks FUSE layer.

  FUSE: Mount with -odev in chroot sandbox
  
  This is needed to permit access to the device nodes added to /dev
  on Linux when FUSE is used as root.
  
  The chroot sandbox only works with all privileges,
  so there's no explicit check for being root
  or having the appropriate capabilities.
  
  A check for whether it's running as root isn't needed on Linux with bubblewrap
  because /dev or its devices are mounted on top of the FUSE layer,
  so device nodes are accessed directly rather than through the FUSE layer.

  Rework Skipped usage
  
  The SKIPPED message type is now used to indicate the end of a task which
  was successful without having to perform the given task.
  
  This overhauls the use of `Queue.done()` and therefore queues do not
  need to provide a processed/skipped return value from `done()`. Instead
  this is replaced with the action of raising a `SkipJob` exception from
  within `Queue.process()`.

  _frontend/status.py: Completely remove the blessings dependency from BuildStream
  
  This actually improves reliability of the status bar because we
  now disable it completely in the case that not all of the terminal
  escape sequences are supported on the given terminal.
  
  This replaces the few functions we were using, to move the cursor
  up one line, move it to the beginning of the line, and to clear a
  line, with low level functions provided by the curses module in
  the standard library.
  
  This change makes it easier for downstream distro package maintainers
  to package BuildStream, particularly on Fedora.
  
  Asides from changing _frontend/status.py, this commit includes the
  following changes:
  
    * _frontend/app.py: Use python isatty() function to determine if
                        we are connected to a tty, instead of relying
  		      on blessings.

  Fix outside-of-project check when project path is not canonical.
  
  The issue happens on Silverblue where /home is a symlink to /var/home.
  With this element-path is something like
  /var/home/user/project/elements, when the project path is
  /home/usr/project. Comparing canonical paths solves the issue.

  Catch correct exception from shutil.rmtree
  
  Python documentation is not clear on what shutil.rmtree is supposed to
  raise. However from the source code, it is obvious that OSError are
  raised, but never shutil.Error.
  
  It is not easy to test in normal condition because issues happen
  usually in combination with a FUSE filesystem, a probably a race
  condition where `fstatat` returns an error just before the filesystem
  being unmounted.

  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.

  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.

  Element: Use cached buildtree in build shells and failure shells
  
  This includes changes in app.py:
  * Interactive failure shell no longer uses the failed build sysroot,
    defaulting to the cached build tree.
  
  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.

  * Fix documentation so Message.sandbox is not a directory any more.

  element: Make "--sysroot" take a bare directory
  
  i.e. instead of taking a directory that must contain "root" and

  In element.py:
  * __sandbox takes the `bare_sandbox` arg, to pass into the sandbox's constructor
  
  In sandbox.py:
  * If bare_sandbox, `_root` is the passed-in directory, and `__scratch`
    is None.
  * Trying to use `__scratch` when bare_sandbox is True is a bug.

  contributing: WIP again to be kind to reviewers

  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.

  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.

  Don't pull artifact build trees by default.
  
  The addition of cached build trees being included in element
  artifacts has led to mostly redundant download overheads when
  pulling from a remote artifact server. As such the default behaviour
  of pull shouldn't fetch the build tree object if available.
  
  element.py: extend relevant pull logic for specified subdir
  consideration and ensure push logic does not lead to partial
  artifact pushes. Change assumption that the buildtree can be
  extracted if artifact is cached. __cached_buildtree() and
  __pull_directories() helpers added.
  
  _artifactcache/: artifactcache.py & cascache.py inclusion of
  helper functions for subdir artifact checking & fetching, fetch
  logic extended to only pull required artifact directories.
  extract & checkout updated to handle full/partial operation.
  
  tests/: addition of integration test pullbuildtrees.py,
  buildtrees.py adapted cli options, testutils/artifactshare.py
  has_artifact changed to return artifact digest on true condition.

  _context: refactor, extract _node_get_option_str
  
  Use a new helper function to simplify working with nodes that can only
  accept certain strings. This will be used when adding the prompt.*
  config options.
  
  In later work we can see if this function would be useful elsewhere, and
  could be added to '_yaml.py'.

  Add prompt.auto-init buildstream.conf option
  
  Provide an option in buildstream.conf to disable the 'Would you like to
  ...' prompt when we cannot resolve a project.
  
  Some users prefer not to be interrupted by such prompts, so pave the way
  to creating options to disable all those that might get in the way.
  
  Follow the example of the advice.* options 'git-config', and create a
  namespace for these UI options grouped by behaviour, rather than an
  over-reaching 'ui.*' namespace. In later work perhaps we'll also add
  'advice.*' options.
  
  Add a NEWS item for this.

  - Add prompt.really-workspace-close-remove-dir

  Add a NEWS item for these.

  man/: update with changes since Apr 2018
  
  It seems that the regenerated man pages haven't been committed for some
  time. Add them all in one lump now.
  
  Had to manually strip the version number from the generated files.
  
  Had to manually fix the NAME field of bst.1 to not be 'bst - None'.
  
  Oddly had to invoke click-man directly in order to get the changes to
  be applied, the usual setup.py route mentioned in contributing.rst
  didn't work.
  
  Eyeballed the result of invoking man on each of the commands, seems

  _stream.py: Ability to pull missing buildtrees outside of pull/build
  
  Adds helper function _buildtree_pull_required() to determine if a
  pullqueue should be constructed, for commands outside of bst pull
  and build where it is determined that an element's buildtree
  artifact is to be required given the respective semantics and
  config. Utilised in push() to attempt to mitigate skipping the push
  of partial elements without the user having to have preceded it with
  an explicit pull.

  Add `--deps build` option to `bst checkout`
  
  As discussed in
  https://mail.gnome.org/archives/buildstream-list/2018-September/msg00064.html,
  add `--deps build` option to `bst checkout`. This will allow users to
  checkout the all build dependencies of a given element using a single
  command.
  
  - _frontend/cli.py: Add `--deps build` option for `bst checkout`.
  
  - element.py: Support `deps='build'` in Element._prepare_sandbox().
  
  - tests/frontend/buildcheckout.py: Ensure `--deps build` works as
    expected.

  Before we would have a intricate logics with multiple arguments
  that might get ignored.
  
  This simplifies the design and introduces a bool `shell` instead

  _scheduler/queues: Don't call update state outside of error handling harness
  
  Commit 3fa79d8da, part of an initiative for caching of the failed builds,
  introduced a call to Element._update_state() after a job completes and before
  entering the error handling harness intended for handling plugin raised errors.
  
  Element._update_state() can result in triggering plugin code to
  run, so this is incorrect, and causes raised errors to crash BuildStream
  if they happen here.
  
  After analyzing the code, it appears that this additional call to
  Element._update_state() is unneeded, and was only added because the
  state needs to be updated for a failure as well as a success.
  
  Instead, we now have the BuildQueue call Element._assemble_done()
  unconditionally, regardless of whether the build was successful
  or not, which has the same effect and also reads better.
  
  In addition, added a FIXME comment that we are still conditionally
  updating the artifact cache size from BuildQueue.done() only
  if the build is successful, which is incorrect because failed builds
  also increase the local artifact cache size - to fix this we need
  to communicate the added artifact size through Element._assemble()
  regardless of whether the build succeeded or failed.

  git source plugin: Track git tags and save them to reproduce a minimum shallow repository
  
  Instead of tag information being fetched which can change with time,
  they are tracked and saved in the projects.refs/.bst. Then we re-tag
  automatically the closest tag so that `git describe` works and is
  reproducible.
  
  This new feature is opt-in with the new `track-tags` configuration,
  and must be used to fix modules which are broken by our new policy
  of omitting the `.git/` repository when staging git sources.
  
  This fixes issue #487

  git source plugin: Implementing submodule warnings
  
   o Unlisted submodule warning
  
     Now the git plugin will issue a configurable warning if a submodule
     exists and is used (checking out the submodule is not disabled),
     but is not specified in the source configuration.
  
   o Invalid submodule warning
  
     Now the git source plugin will issue a warning if the configuration
     specified a submodule which does not exist in the underlying git repository.
  
  As a side effect, this patch also changes the flow control of the git
  plugin such that submodules which are explicitly set to not be
  checked out, are also not fetched but instead ignored completely.

  This also allows us to remove the `self.tracked` local state, and cleanup
  some convoluted calling paths, removing some unnecessary parameters from
  the usual codepaths and making the plugin overall more readable.

  _yaml.py: Added `allow_none` parameter to _yaml.node_get()
  
  This allows specifying whether or not the code believes a None
  value is acceptable if explicitly expressed to be None in the YAML.
  
  A previous patch 3ba544b80f9f268be8ffe62fc8589b30212ec4a2 changed
  the behavior to accept None for all values across the board, along
  with allowing explicitly setting the `default_value` to `None` which
  caused the code to be much more readable (this was the main motivation
  of the patch, but it had the side effect of allowing None for everything).
  
  In the majority of cases we load YAML however, it either has a value or
  it is not specified in the YAML, and None is hardly ever acceptable
  to be explicitly specified (it may be in the case you want to override
  something with nothing in the YAML, but it is the edge case).
  
  This had the side effect of causing unexpected crashes where the
  YAML specifies an empty dictionary for instance.
  
  Instead of forcing the caller to handle a possible None value, give
  the choice to the caller if they really want to accept a None value,
  and raise the LoadError otherwise.
  
  This fixes issue #803, which is a crash due to receival of an
  unexpected None value through _yaml.node_get()

    as an optional argument. Because click gets confused if there's an
    optional argument before a mandatory argument, I had to mark LOCATION
    as optional internally.
  * `bst workspace open` makes no sense with element being optional, so
    I skipped it.
  * `bst workspace close` will probably need to be revisited when multiple
    projects can own one workspace.
  * `bst workspace reset` will happily delete the directory you're
    currently in, requiring you to `cd $PWD` to see the contents of your
    directory.
    I could exclude the top-level directory of the workspace being
    deleted, but it is entirely valid to run workspace commands from deeper
    in the workspace.

  contributing: mandate end-to-end tests, allow others
  
  Update the section on adding tests, to fulfill these broad points:
  
  - Mandate end-to-end testing, with rationale.
  - Mention internal APIs as endpoints for testing.
  - Warn against pitfalls of unit-testing.
  
  It's more text than I would have liked, perhaps in later work we'll be
  able to say it with less.

  Introduce new "source" command group
  
  Following the message thread
  https://mail.gnome.org/archives/buildstream-list/2018-November/msg00106.html,
  implement a new command group called `source`. Move existing `track`,
  `fetch`, and the recently added `source-checkout` commands under this
  group.
  
  For `track` and `fetch`, this is a BREAKING change, as the old commands
  have been marked as obsolete. Using them will result in an error message
  that refers people to use the new versions, like `bst source fetch`
  instead of old `bst fetch`. `source-checkout` will now become
  `source checkout` (the dash has turned into a space), and is not a
  breaking change as it was added in the current development cycle.
  
  Note that the functionality to hide commands from help output was added
  only recently in Click, so the minimum version of Click that we now
  require is 7.0.
  
  Summary of changes:
  
  * _frontend/cli.py: Add `source` command group, mark previous versions
    as obsolete and hide them from the help output.
  * _frontend/complete.py: Fix completion for hidden commands.
  * setup.py: Bump Click minimum version to 7.0.
  * tests: Update to cope with the new command names.
  
  Fixes #814.

  Expose base class for Git source plugins
  
  Add a `_GitSourceBase` class to act as the base class for deriving
  source plugins that work with Git. The first user of this base class is
  the `git` source plugin that's in core at the moment.
  
  The contents of this base class is almost identical to the existing `GitSource`
  class. The two notable differences are:
  
  - the private methods now have leading underscores, as some were missing
    it originally
  - the name of the class
  
  Note that we are exposing a private member here as we expect it to move to a
  separate package soon. See the following discussion for more details:
  https://gitlab.com/BuildStream/buildstream/issues/739#note_124819869
  
  Fixes #739.

  Now that we are also looking for WORKSPACE_PROJECT_FILE, we should add
  it to the error message. While we're there, also mention the directory
  we are looking in - this could help scripters be clear about what went
  wrong.

      Error loading project: None of ['project.conf', '.bstproject.yaml']
      found in '/src/temp/blah' or any of its parent directories

  BREAK: remove auto-init behaviour
  
  In the event that the project could not be found, stop BuildStream from
  asking if the user would like to create a new project. Exit with error
  instead, and give a hint to the user in case they're new.
  
  As proposed on the mailing list here:
  https://mail.gnome.org/archives/buildstream-list/2018-December/msg00082.html
  
  The new interaction looks like this:
  
      $ bst show nonsuch.bst
      No project found. You can create a new project like so:
  
          bst init

  Add requirements files for install, test and plugin dependencies
  
  Add `.in` and `.txt` requirements files for BuildStream's pure python
  dependencies. For each pair, the `.in` file is supposed to capture the
  loose version requirements, and the corresponding `.txt` file is
  supposed to have frozen requirements. We have 3 such sets:
  
  * `requirements`: BuildStream's runtime dependencies
  * `dev-requirements`: Dependencies for running tests
  * `plugin-requirements`: Dependencies for core plugins
  
  Note that the frozen requirements files will only be used for testing
  purposes, and `setup.py` will continue to read loose requirements.

  Since we don't allow use of site packages by default in our `tox`
  configuration, people will need to install non-python build dependencies
  of some of our dependencies that do not provide pre-built wheels. We
  have two such packages at the moment:
  
  * psuitl: requires python C headers, compiler
  * pygobject: requires python C headers, pkg-config, compiler, cairo
    headers, and gobject libraries

  tests/frontend/buildcheckout.py: Fix bad filename issue for Windows
  
  In BuildStream/buildstream!1028, we added a test specifically to test
  that BuildStream correctly raises an warning when the name of an element
  contains characters that are invalid on Windows. Unfortunately, we
  didn't see it coming that it would make it impossible to checkout this
  branch on Windows.
  
  Fix it by generating this file, only if we are not running on Windows.
  
  * tests/testutils/site.py: Add `IS_WINDOWS` check
  * tests/frontend/buildcheckout.py: Generate file with invalid filename
    on the fly
  * Remove tests/frontend/project/elements/invalid-chars.
  
  Fixes #842.
  
  Note that this may still cause issues on WSL when running tests on a

    * utils.py:_kill_process_tree(): Ignore NoSuchProcess errors

  It seems that we were ignoring it after sleeping when terminating

  we were still getting these exceptions at termination time from host

  _scheduler/scheduler.py: Only run one cache size job at a time
  
  When queuing the special cache management related cleanup and
  cache size jobs, we now treat these jobs as special and do the
  following:
  
    * Avoid queueing a cleanup/cache_size job if one is already queued
  
      We just drop redundantly queued jobs here.
  
    * Ensure that jobs of this type only run one at a time
  
      This could have been done with the Resources mechanics,
      however as these special jobs have the same properties and
      are basically owned by the Scheduler, it seemed more straight
      forward to handle the behaviors of these special jobs together.

  Scheduler: Introduced JobStatus instead of simple success boolean
  
  This changes the deepest callback from when a Job completes to
  propagate a JobStatus value instead of a simple boolean, and updates
  all of the effected code paths which used to receive a boolean

  Support running test environments in parallel with `detox`
  
  This patch namespaces the test temp directory and the output
  coverage report file with the name of the environment under test,
  such that separately run tests do not access the same files.
  
  When running tests without tox, directly through setup.py,
  then the tmp directory will still be `./tmp`.
  
    * .gitignore: Added new .coverage-reports/ directory
  
    * .gitlab-ci.yml: Rely on tox to combine and report coverage, only
      tell tox about the COVERAGE_PREFIX so that results can be namespaced
      by CI job name.
  
      This change also publishes the sources and final combined `.coverage`
      file in an output gitlab artifact for inspection, and lists some missing
      dependencies to the `coverage` job.
  
    * tox.ini: Add comments and refactor main [testenv] section so that
      other environments dont inherit too much unrelated cruft.
  
      Generate the coverate reports in the respective {envtmpdir} so that
      all per-process coverage files are prefixed with a full path, ensuring
      that concurrent runs don't mix reports and addressing concerns
      raised in #844.
  
      Also implemented new `tox -e coverage` environment to combine
      any found coverage and print a report.
  
    * .coveragerc: Omit .tox/ directory from coverage stats
  
  Fixes issue #844

  Bump the version of pytest-cov, so that we pick up the fix for
  the '--no-cov' option breaking in pytest 4.0:
  
      https://github.com/pytest-dev/pytest-cov/pull/230
  
  This was the error you would get prior to this version:
  
      _pytest.warning_types.RemovedInPytest4Warning: config.warn has been
      deprecated, use warnings.warn instead
  
  Although it says 'deprecated', it did result in
  termination with stack trace.

  _scheduler/queues/queue.py: Put elements in the skip list, not jobs
  
  Minor correction, looks like we're not observing this queue
  otherwise we'd be seeing crashes.

  .gitlab-ci.yml: Use newer image for overning aarch tests
  
  During recent reorganizing of `.gitlab-ci.yml` to work with `tox`, seems
  like we missed to update the image used by the overnight aarch tests,
  meaning that they currently fail due to `tox` being missing from them.
  
  While these tests will be skipped on MRs usually, here is an example of
  what the tests look like if they are actually run with this change:
  https://gitlab.com/BuildStream/buildstream/-/jobs/145449561.
  
  Fixes #859.

  _frontend/cli.py: Also check original args for --config in bash completion
  
  The path of the config file generated by testutils for completion tests
  is passed as regular argument, not via COMP_WORDS. Use that config file
  in complete_artifact() to ensure the test uses the right artifact
  directory.

  completions.py: Add a test for our artifact ref autocompletions
  
  Since the artifact subcommand group has been created, we have been able
  to tab complete both element names and artifact refs as arguments to
  the artifact subcommands (e.g. bst artifact log), this commit adds a
  test for this.

  .gitlab-ci.yml: Add job to attempt to update dependencies
  
  This will help us check if BuildStream is working with the latest
  version of dependencies, as per our constraints. This job is allowed to
  fail but its failure should signal that we need to add stricter
  constraints in some of our `.in` requirements files.
