Pytest moved its cache from `./.cache` (which is in our `.gitignore`) to
`./.pytest_cache` (which isn’t).
It’s annoying having to be careful not to commit it all the time, so
this commit makes it ignored.
See https://github.com/pytest-dev/pytest/issues/3286 for more context.
I don’t think we’re getting any benefit from it. Especially since we’re
not running any Node code in production, but just using it to build the
frontend.
The downside is we keep getting these massive diffs which means we don’t
get an accurate line count on pull requests.

Previously we used AWS which meant that we could create wheels
from our requirements and then install them offline which made
deployments quicker.
We're no longer using AWS so let's remove that.
Although CloudFoundry supports installing dependencies in an offline
environment as documented here:
http://docs.cloudfoundry.org/buildpacks/python/#vendoring
To achieve this we create a vendor/ directory which will contain
the packages to install. This uses --no-index and --find-links so will
not resolve for any dependencies from pypi. For this reason there is
assumed confidence that the vendor/ directory will contain all
of the dependencies we need.
…or how to move a bunch of things from a bunch of different places into
`app/static`.
There are three main reasons not to use Flask Assets:
- It had some strange behaviour like only
- It was based on Ruby SASS, which is slower to get new features than libsass,
and meant depending on Ruby, and having the SASS Gem globally installed—so
you’re already out of being a ‘pure’ Python app
- Martyn and I have experience of doing it this way on Marketplace, and we’ve
ironed out the initial rough patches
The specific technologies this introduces, all of which are Node-based:
- Gulp – like a Makefile written in Javascript
- NPM – package management, used for managing Gulp and its related dependencies
- Bower – also package management, and the only way I can think to have
GOV.UK template as a proper dependency
…speaking of which, GOV.UK template is now a dependency. This means it can’t be
modified at all (eg to add a global `#content` wrapper), so every page now
inherits from a template that has this wrapper. But it also means that we have a
clean upgrade path when the template is modified.
Everything else (toolkit, elements) I’ve kept as submodules but moved them to a
more logical place (`app/assets` not `app/assets/stylesheets`, because they
contain more than just SASS/CSS).
Since GOV.UK Elements is versionned now it makes sense to bring it in as a
dependency. This enforces a separation between what generic stuff we’re using
from Elements and what is specific to our app.
The benefit is that when the generic stuff changes it will be easy to bring
those changes in.
This commit also bumps GOV.UK frontend toolkit to the latest version (v4.5.0).
