  * plainbox:commands: show 'steps' information in CLI for manual jobs
    This patch fixes a problem where plainbox would omit showing
    'steps' field in CLI clients when running manual jobs. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1453067
  * plainbox:commands: print field headers This patch makes CLI front-
    ends print 'Purpose:', 'Steps:' and 'Verificaiton:' text before
    printing contents of the corresponding fields. This should make
    interaction with plainbox more digestable. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1453070
  * plainbox:commands:inv_run: fix wrong reporting of estimated_time
    This patch fixes reporting of time left in the session.
  * plainbox:commands: add progress notification before starting each
    job This patch makes plainbox report current progress (how many
    jobs are done, out of how many, what's the estimated time to
    complete the session). This notification is visible when using
    both: plainbox run and checkbox with new-ui. Fixes:
    https://bugs.launchpad.net/checkbox-ng/+bug/1392123
  * plainbox:commands:inv_run: add seconds_to_human_duration funtion
    This patch adds a function that converts number of seconds to
    human readable string. It should be used when front-ends want to
    display projected time left in a current testing session
  * plainbox: add *.html from plainbox/data/ to MANIFEST.in Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1443472
  * plainbox:box: load exporters for stubbox
  * plainbox:docs: update examples using --output-format
  * plainbox:exporter:hexr: export IO logs for just the attachments
    The original XML exporter iterated over attachment map, we're
    iterating over the job state map so we should filter out non
    attachment jobs explicitly. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1464653
  * plainbox:exporter:hexr: add additional tests
  * plainbox:exporter:html: use correct loop index for re-runs
  * checkbox-ng:service: log extra warnings when results cannot be
    removed
  * plainbox: ship hexr .xml template Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1463705
  * plainbox:exporter:html: display result history
  * plainbox:exporter:text: display result history
  * plainbox:session:result: replay the full result history
  * plainbox:session:suspend: store full result history
  * plainbox:session:jobs: keep track of result history
  * plainbox:result: remove all setters and change signals
  * plainbox:exporter:hexr: fix escaping test The original test
    injected "evil" data by setting the _io_log attribute (note the
    leading underscore). This was easily mistaken since the original
    code was accepting any attributes. I spotted this during the job
    result builder conversion and decided to fix it properly.
  * plainbox:exporter:hexr: use JobResultBuilder
  * plainbox:commands:run: use JobResultBuilder This patch changes all
    of the result handling in the implementation of "plainbox run" to
    rely on job result builder. This is done to avoid any modification
    of existing results and instead, if appropriate, construction of
    new results. One minor detail is that the timing measurements are
    now done at a lower level, where we still have the result builder.
  * plainbox:runner: use JobResultBuilder everywhere This patch
    changes all of the code to use JobResultBuilder. This change has
    two implications. First we don't need to construct concrete result
    types anymore so all of the code is more consistent. Second of
    all, some private, helper methods now return a builder object,
    instead of a result. This is done so that the caller can still
    modify the result before finally returning a sealed result object
    out of the JobRunner methods.
  * plainbox:result: add _JobReturnBase.get_builder() To complement
    the JobResultBuilder.get_result() we have
    {Memory,Disk}JobResult.get_builder(). During the current
    transition it might be helpful to construct and de-construct
    result objects (as we get new objects all the time we don't
    trigger any modification warnings).
  * plainbox:result: add JobResultBuilder This patch adds a new class
    that assists in building appropriate JobResult objects. The result
    builder has a .get_result() method that returns a regular result
    (of the appropriate kind, either disk or memory). The idea is to
    make the result immutable later on and only allow modification to
    happen inside the builder.
  * plainbox:exporter:html: remove redundant calls to
    get_certification_status_map()
  * plainbox:exporter:html: remove commented-out css rule
  * plainbox:exporter:html: don't use deprecated -vendor properties
  * plainbox:exporter:html: fix some inconsistent css syntax
  * plainbox:exporter:html: remove unused css rules
  * plainbox:exporter:html: inline checkbox.js
  * plainbox:exporter:html: inline checkbox.css
  * plainbox:exporter:html: use a variable for job_state_map
  * plainbox:exporter:html: use a variable for resource_map
  * plainbox:exporter:html: don't spell the long namespace over and
    over
  * plainbox:exporter:html: remove useless newlines
  * plainbox:exporter:html: remove useless OOM object
  * plainbox:exporter:html: fix broken substitution on tr_outcome
  * plainbox:exporter:html: re-factor construction of test data This
    patch replaces the large mocking constructs that provided test
    data for the html exporter with real objects. It is actually much
    shorter and easier to set it up this way.
  * plainbox:exporter: add HEXR exporter This patch adds a new
    exporter (HEXR) that is intended to replace our current "xml"
    exporter. The schema is specific to the Canonical HEXR application
    so the name reflects that. Note that due to the syntax used, this
    exporter requires Jinja2 >= 2.7. The dependency wasn't there
    before so I've added it to install_requires.
  * plainbox:exporter:jinja: add support for customizing Environment
    The environment is how you control all of jinja's behavior.
    Currently the environment is hidden in the initializer of the base
    jinja exporter class. By having a method where we can customize
    the environment _before_ a template is loaded we can add anything
    (additional tests and filters). After a template is initialized,
    those changes don't affect the template.
  * plainbox:providers:special: allow passing keyword args to
    get_stubbox() The provider constructor seems to call the old
    validate API. Since this is pretty annoying (all the incorrect
    things the old validation says) I wanted to have a way to disable
    that by passing validate=False, check=True. This is a quick stop-
    gap measure. In reality we want to purge all the old validation
    code.
  * plainbox:stubbox: add set of representative jobs This patch adds a
    number of jobs that validate and don't do anything. Each job has
    an identifier that looks like "representative/plugin/{plugin}".
    The goal of this collection is to simplify unit tests that
    traditionally re-created everything using python APIs (which is
    both fragile and more verbose).
  * plainbox:resource: make it possible to iterate over resources
    Iterating over resources behaves just like iterating over
    dictionaries (keys are returned). This is useful to access
    resource elements in Jinja templates. In the past we just accessed
    ._data directly but this is a hack and we should get rid of it.
  * plainbox:commands:check_config: produce more useful output This
    patch changes the 'plainbox check-config' command so that it is
    immediately obvious which ini-file section each variable belongs
    to. I found that I didn't remember some settings and I had to go
    and chase the code to see the definitions. With this tweak, each
    variable looks like a part of the actual ini file so everything is
    obvious.
  * plainbox:pod: add Field.change_notifier This patch adds a new
    decorator that can be used similarly to @foo.setter (when foo is a
    @property-decorated method). This can simplify all fields that
    need to have a custom notification method. All such methods can be
    implemented _after_ all of the field definitions now.
  * plainbox:pod: filter-out UNSET from as_dict() Normally UNSET
    values don't exist in a POD for a long time. Typically they are
    only used briefly during POD initialization. If the developer uses
    a custom default value and actually uses UNSET (or assigns UNSET
    explicitly) then as_dict() will misbehave, producing the UNSET
    value again (which is implicit). This patch changes as_dict() so
    that it doesn't propagate them to the dict representation. Note
    that this is different from the as_tuple(), which cannot avoid
    representing UNSET.
  * plainbox:pod: add unset variants for type assignment filters This
    patch adds pod.unset_or_typed and pod.unset_or_typed.sequence
    assign filters. Those two new filters allow to use UNSET values
    (when explicitly desired) and still get a benefit from the type
    checks that typed and typed.sequence offer. UNSET acts as a kind
    of variant of None, offering nullable types. This is not the best
    way to do it but I wanted to have a distinction between None and
    UNSET so that None can be used normally.
  * plainbox:pod: fix copy-pasted docstring
  * plainbox:pod: fix sequence_type_check_assign_filter() This patch
    fixes a silly issue in sequence_type_check_assign_filter() that
    wasn't tested. The raised exception should have mentioned the type
    of the sequence elements, not the type of the actual sequence.
    Yes, tests find bugs. Untested code is almost always broken.
  * plainbox: use @morris.signal instead of @signal This patch changes
    all of the code that looks like @signal def blah(...): ... To look
    like this instead: @morris.signal def blah(...): ... This prevents
    us from shadowing the stdlib signal module by accident. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1442175
  * plainbox:resume: enable 5th resume helper
  * plainbox:resume: split tests for DiskJobResult 1-4 and 5 This
    patch splits unit tests for DiskJobResult in formats 1 through 4
    and in the 5th format. Tests for the 5th format check the extra
    conditions and behavior related to relative and absolute pathnames
  * plainbox:resume: add 5th resume helper
  * plainbox:resume: use absolute path for DiskJobResult resume test
    An absolute path is more realistic. Using it will also help with
    the upcoming 5th format.
  * plainbox:resume: add SessionResumeHelper1._load_io_log_filename()
    This patch moves a part of SessionResumeHelper1._build_JobResult()
    method to a new, tiny method so that it can be overriden
    separately for 5th resume format.
  * plainbox:resume: enable extra testing for 4th format
  * plainbox:resume: make SessionResumeHelper1.__init__(...) arguments
    mandatory This patch makes the flags and location arguments of
    SessionResumeHelper1 mandatory in anticipation of the fifth resume
    format that relies on a sane value of "location"
  * plainbox:resume: better docstring for
    SessionResumeHelper1.__init__()
  * plainbox:resume: better docstring for
    SessionResumeHelper.__init__()
  * plainbox:resume: make _build_JobResult(flags, location) mandatory
    This patch makes all of the arguments to _build_JobResult()
    mandatory.
  * plainbox:resume: pass flags and location to _build_JobResult()
    This patch modifies all calls to _build_JobResult() so that flags
    and location arguments are provided. This will allow to make them
    mandatory later. The intent is to make them mandatory as they will
    be required for 5th resume format and all non-test code already
    uses them.
  * plainbox:resume: make SessionResumeHelper.__init__() args
    mandatory This match makes it mandatory to pass the location and
    flags arguments to the session resume helper. This is done so that
    the location argument is not omitted by accident anywhere.
    Location will be mandatory soon, with the 5th resume format.
  * plainbox:resume: fix PEP-8 issue
  * plainbox:resume: fix typo
  * plainbox:manager: pass 2nd argument to suspend() This patch makes
    the session manager pass the session_dir hint argument to the
    suspend helper. This way the helper can optimize the
    representation of the session to that directory.
  * plainbox:suspend: switch to 5th format by default
  * plainbox:suspend: add 5th suspend format This patch adds the fifth
    suspend format. This format is the same as the fourth format with
    the exception of how DiskJobResult is saved. If the new (but still
    optional) session_dir argument is provided then a relative
    pathname to each DiskJobResult is saved instead of an absolute
    one. This allows the whole session to be relocated easily. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1378295
  * plainbox:suspend: use a more convenient io_log_pathname
  * plainbox:session: decouple helper class from tests
  * plainbox:suspend: push session_dir to all helper methods This
    patch pushes the session_dir argument to all of the helper methods
    on all of the SessionSuspendHelper1 subclasses.
  * plainbox:suspend: add session_dir argument to suspend() This patch
    adds a new optional argument to SessionSuspendHelper1.suspend().
    The optional argument can be used to tell the suspend helper where
    the data will be stored. This can be used to use relative
    pathnames inside the representation.
  * plainbox:pod: add @podify decorator This patch adds a new
    decorator, @podify, that converts any class that inherits from
    PODBase to a POD-lookalike. This way one can make PODs out of
    classes with custom metaclasses as well as use POD-based
    exceptions.
  * plainbox:pod: move POD methods to new PODBase class This patch
    moves all of the methods unique to a POD to the new PODBase class.
    This class has no metaclass and can be inherited by anything that
    wants to do so.
  * plainbox:pod: use field.counter to determine field ordering This
    patch changes _FieldCollection.inspect_namespace() to use
    field.counter to detect ordering of Field() entries as they appear
    in the source code. This will make it possible to drop the
    requirement to use the __prepare__() method later.
  * plainbox:pod: add .counter to each Field. This patch adds a ever-
    incrementing counter to each Field instance. This field can be
    used to look at the order in which particular fields were defined
    when we cannot control the namespace in which a class is defined
    in (via the __prepare__ metaclass method)
  * plainbox:pod: fix PEP-8 issues
  * plainbox:pod: fix PEP257 issues
  * providers:checkbox: don't use dbus-launch Using dbus-launch is
    always wrong, as explained in the bug linked below. Fixes:
    https://bugs.launchpad.net/plainbox-provider-checkbox/+bug/1377266
  * plainbox:commands:run: don't crash when job has unknown duration
    This patch fixes a crash that happens when a job has unknown
    estimated duration. It also ensures that the UI looks useful when
    that happens by changing the estimate to "unknown". Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1445030
  * plainbox:depmgr: add extra debugging logs
  * plainbox:depmgr: replace integers with Color enumeration values
  * plainbox:depmgr: add Color enumeration This patch adds a classic
    three-value color enumeration for graph traversal algorithms.
  * plainbox:depmgr: fix PEP257 issues and improve docstrings. Most of
    the changes are related to ensuring proper spacing and
    punctuation. Some changes are re-wording docstrings for
    consistency among similar classes.
  * plainbox:unit:job: materialize imports before passing to resource
    program This patch fixes an interesting bug where a "imports" line
    would only work for the first out of all the requirements. The
    reason for this is that the implementation of the imports system
    uses a generator and the resource program iterates over that
    iterator more than once. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1444242
  * plainbox:public: add get_providers This patch exposes
    get_providers() as the first public method (apart from main).
  * plainbox.public: load functions lazily This patch replaces the old
    '@public' decorator with LazyModule.
  * plainbox:lazymod: add the _lazymod module This patch adds a copy
    of code from python-glibc (that I also wrote) that simplifies
    creation of 'lazy modules'. Those modules can conveniently expose
    various objects (functions, classes, anything really) and only
    load it on demand. I intend to use it for the public module to
    work around some circular import issues that were present with the
    older approach that did all of the imports immediately.
  * plainbox:providers: add get_providers() function This patch adds a
    new (public) function that addresses the problem of confusing APIs
    for loading all available providers. Unlike past approaches this
    is a simple function, it's not a class nor an object with complex
    API. This should make it easier to understand and use within
    applications.
  * plainbox:providers: remove stray newline from the license
  * plainbox:ctrl: skip non-jobs printed by local jobs This patch
    makes the session state controller skip non-job units that are
    printed by local jobs. In theory we could add more units this way
    but the code for handling that is ugly as it is, without the
    holding area, so this is the better compromise. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1443228
  * plainbox:ctrl: use real RFC822 record for testing This patch
    changes some tests to use a real RFC822 record for testing session
    controller code. The intent is to let that real record behave
    correctly when upcoming code inspects it for some data.
  * providers:manifest: add use-chunked-io flag to collect-manifest
    job
  * plainbox:commands:run: flush on each part of IO This patch enables
    explicit flush on each write that came from a job process. This is
    normally line-based IO for all the text-based jobs. When using
    CHUNKED_IO with legacy thread+blocking IO extcmd this is actually
    triggered on each byte read so we get "live" output, as it
    happens.
  * plainbox:commands:run: preserve original line endings for display
  * plainbox:runner: use CHUNKED_IO for jobs that request it This
    patch enables CHUNKED_IO mode for jobs that have the 'use-chunked-
    io' flag.
  * plainbox:vendor:extcmd: use 1-byte buffers for legacy chunked IO
    This patch is a hack to get to an useful effect from legacy
    (thread based) chunked IO implementation. By default chunked mode
    used a 4K buffer which was a reasonable value for bulk data
    transfers. Since the blocking API doesn't allow us to see anything
    before the whole buffer gets full we cannot use it to get things
    like interactive prompts to work. In order to fix bug
    https://bugs.launchpad.net/plainbox/+bug/1443911 I wanted to use
    chunked IO (and it works great in glibc mode which uses non-
    blocking IO). To use chunked IO in thread + blocking mode we can
    cheat and use 1-byte buffers. That is, each byte that gets written
    to a pipe gets read and reported to the application. This is
    slower and by far, but it gets the job done. Since chunked IO is
    enabled selectively and so far only the manifest job enables it,
    it's a safe hack / compromise.
  * plainbox:vendor:extcmd: add support for chunked I/O This patch
    adds a way to do non-line-based I/O via extcmd. Line base I/O is
    perfect for text but can be problematic and inefficient for binary
    data. By allowing applications to pass the new CHUNKED_IO flag to
    extcmd, they can now opt-into the new behavior (per extcmd
    instance) which calls the new on_chunk() delegate method, instead
    of the old on_line() method.
  * plainbox:depmgr: don't crash when directly solving unknown jobs
    This patch changes the DependencyManager class not to crash when
    asked to solve the dependency chain of a given job, directly (as
    if it was placed on the desired_job_list) but the job is not
    present in the solver copy of job_list. Instead of raising
    KeyError, a new error (subclass of DependencyError)
    DependencyUnknownError is raised. This error is handled uniformly
    by the SessionState class so everything works as expected. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1334296
  * plainbox:state: add fix and regression test for 1444126 This patch
    fixes a bug in SessionState.update_desired_job_list() that could
    cause a job to be removed twice (causing ValueError to be raised).
    As explained in the associated regression test, the problem is
    caused by the following chain of dependencies: A -> B -> C The
    session knows about jobs A and B, C is unknown. We want A and B
    The solver loop results in the following actions: - (A depends on
    B so we go to B and notice that it depends on C). - B gets removed
    from desired_job_list because C is unknown
    (DependencyMissingError). - The problem is recorded and we try
    again (another solution, this time just looking for [A]) - (A
    depends on B so we go to B and notice that it depends on C) -
    Crash, B was already removed! The fix also involves removing jobs
    from the set of known jobs because otherwise an endless loop
    occurs: - (A depends on B so we go to B and notice that it depends
    on C). - B gets removed from desired_job_list because C is unknown
    (DependencyMissingError). - The problem is recorded and we try
    again (another solution, this time just looking for [A]) - (A
    depends on B so we go to B and notice that it depends on C) - B
    was already removed so we don't do anything and we try again
    (oops!, nothing has changed we'll be here forever) Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1444126
  * plainbox:depmgr: add DependencyMissingError.__hash__()
  * plainbox:depmgr: add DependencyMissingError.__eq__()
  * checkbox-ng: load manifest provider This patch makes checkbox-ng
    use extra APIs to load the manifest provider. This is not the best
    way to solve it as plainbox should really just load all of the
    special providers as well but for now this will have to do. There
    will be separate patches to fix the provider API next. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1443895
  * plainbox:testplan: don't crash if id is not set This patch
    prevents a crash that can happen when a test plan doesn't have an
    ID field. This is normally validated separately but the context
    validator (which does other checks) should be written defensively
    and not assume that each unit is correct. Here the problem was
    related to trying to come up with a regular expression match of a
    None id against some unrelated test plan pattern. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1443899
  * checkbox-ng:ui: don't crash if there are no nodes to toggle This
    patch fixes the 'toggle' feature where the test operator can press
    enter to expand/collapse a test node. Since having no nodes at all
    is possible (though not common) it's required to check if we got a
    node in the first place before going to toggle it's state. Fixes:
    https://bugs.launchpad.net/checkbox-ng/+bug/1443901
  * plainbox:manifest: correct location of the hardware manifest This
    patch adds the missing 'share/' directory part to closer mimic the
    XDG_DATA_HOME directory. Fixes:
    https://bugs.launchpad.net/plainbox/+bug/1443903
  * plainbox:ctrl: detect and break via cycles This patch changes the
    CheckBoxSessionStateController to pay extra attention not to
    create via cycles when processing local jobs. Fixes: https://bugs.
    launchpad.net/plainbox/+bug/1441993https://bugs.launchpad.net/plai
    nbox/+bug/1441993
  * plainbox:ctrl: add get_via_cycle() This patch adds a function that
    detects cycles in via connections.
  * plainbox:ctrl: rewrite tests for local jobs This patch rewrites
    three tests for local jobs, not changing their semantics but
    changing the implementation. The original implementation used
    mocking for everything and focused on observing impact of the
    session controller on the mocked session. This turned out to be
    difficult to adapt to changes to the controller so instead non-
    mocked objects are used and minimal mocking is used as a short-cut
    (to remove the necessity to create real results that correctly
    define jobs).
  * plainbox:exporter: remove unnecessary xml import in html exporter
  * Fix missing info in the HTML report (requirements and blocker
    sections)
  * plainbox: remove dependencies on lxml This patch removes all of
    the remaining mentions of lxml.
  * plainbox:exporter:xml: Remove the old XML exporter module Remove
    dependency and references to lxml
  * plainbox:data:report: Remove the hexr/html templates from
    plainbox/data They are now the PROVIDER_DATA directory of the
    exporter special provider.
  * plainbox:exporter: Remove old html/hexr exporters Those are now
    entirely generated using the Jinja2 exporter
  * plainbox:secure:config: Allow keys w/o values and set '=' as
    unique delimiter
  * plainbox:setup.py: Use the HEXR exporter to generate XML
  * plainbox:commands:run: Load exporters from their units `plainbox
    -f` now only accept valid exporter unit ids. The exporter is
    created after we get a session to query the manager and get all
    exporter units
  * plainbox:exporter: Update exporters __init__() with an
    exporter_unit argument All exporters get a new argument called
    exporter_unit meant to store the new ExporterUnitSupport.
    Exporters can now have access to the custom data property and
    tweak the reports in many ways. Options are still a positional
    argument but can be extended by options set in the data field of
    the exporter unit, in the "extra_options" key. The Jinja2 exporter
    adds to the list of paths where to look for templates the special
    PROVIDER_DATA directory of the exporter unit. Providers can now
    ship new templates for Jinja2 based exporters (HTML is obviously a
    perfect candicate) Both the HTML and HEXR exporter classes are now
    merged into their base Jinja2 exporter class.
  * plainbox:exporter:text: Fix Colorizer import
  * plainbox:session:manager: Add the exporter_map property A Map from
    exporter id to the corresponding exporter support unit. This is
    the preferred way to get such units as the manager knows all the
    loaded providers and their related units. Note: Only units passing
    the validation check() are kept.
  * plainbox:providers: Special provider for existing exporters The
    xlsxwriter package is now mandatory (at least for development)
  * plainbox:unit:exporter: New unit type allowing exporter
    customization The mandatory fields are the unit id and the
    setuptools entry point to call. The exporter summary will be used
    by the `plainbox run -f ?` command. The exporter_cls method is the
    target of the entry point. If plainbox cannot load the entry point
    it will exit automatically. The data field is a special optional
    field meant to be used to pass a complex object to the exporter.
    As RFC822 was not suitable for such container, the data field must
    be in JSON format. E.g: data: { "foo": "bar", "baz": [ 1, 2, 3] }
