Elliot Smith 952ffb3e1f bitbake: toaster: move most recent builds templating to client
The most recent builds area of the all builds and project builds
table needs to update as a build progresses. It also needs
additional functionality to show other states (e.g. recipe parsing,
queued) which again needs to update on the client side.

Rather than add to the existing mix of server-side templating
with client-side DOM updating, translate all of the server-side
templates to client-side ones (jsrender), and add logic which
updates the most recent builds area as the state of a build changes.

Add a JSON API for mostrecentbuilds, which returns the state of
all "recent" builds. Fetch this via Ajax from the build dashboard
(rather than fetching the ad hoc API as in the previous version).

Then, as new states for builds are fetched via Ajax, determine
whether the build state has changed completely, or whether the progress
has just updated. If the state completely changed, re-render the
template on the client side for that build. If only the progress
changed, just update the progress bar. (NB this fixes the
task progress bar so it works for the project builds and all builds
pages.)

In cases where the builds table needs to update as the result of
a build finishing, reload the whole page.

This work highlighted a variety of other issues, such as
build requests not being able to change state as necessary. This
was one part of the cause of the "cancelling build..." state
being fragile and disappearing entirely when the page refreshed.
The cancelling state now persists between page reloads, as the
logic for determining whether a build is cancelling is now on
the Build object itself.

Note that jsrender is redistributed as part of Toaster, so
a note was added to LICENSE to that effect.

# Running Toaster's browser-based test suite

These tests require Selenium to be installed in your Python environment.

The simplest way to install this is via pip:

  pip install selenium==2.53.2

Note that if you use other versions of Selenium, some of the tests (such as
tests.browser.test_js_unit_tests.TestJsUnitTests) may fail, as these rely on
a Selenium test report with a version-specific format.

To run tests against Chrome:

* Download chromedriver for your host OS from
  https://sites.google.com/a/chromium.org/chromedriver/downloads
* On *nix systems, put chromedriver on PATH
* On Windows, put chromedriver.exe in the same directory as chrome.exe

To run tests against PhantomJS (headless):

* Download and install PhantomJS:
  http://phantomjs.org/download.html
* On *nix systems, put phantomjs on PATH
* Not tested on Windows

To run tests against Firefox, you may need to install the Marionette driver,
depending on how new your version of Firefox is. One clue that you need to do
this is if you see an exception like:

  selenium.common.exceptions.WebDriverException: Message: The browser
  appears to have exited before we could connect. If you specified
  a log_file in the FirefoxBinary constructor, check it for details.

See https://developer.mozilla.org/en-US/docs/Mozilla/QA/Marionette/WebDriver
for installation instructions. Ensure that the Marionette executable (renamed
as wires on Linux or wires.exe on Windows) is on your PATH; and use "marionette"
as the browser string passed via TOASTER_TESTS_BROWSER (see below).

(Note: The Toaster tests have been checked against Firefox 47 with the
Marionette driver.)

The test cases will instantiate a Selenium driver set by the
TOASTER_TESTS_BROWSER environment variable, or Chrome if this is not specified.

Available drivers:

* chrome (default)
* firefox
* marionette (for newer Firefoxes)
* ie
* phantomjs

e.g. to run the test suite with phantomjs where you have phantomjs installed
in /home/me/apps/phantomjs:

PATH=/home/me/apps/phantomjs/bin:$PATH TOASTER_TESTS_BROWSER=phantomjs manage.py test tests.browser
