Before this commit, the posbox was built and in the process the permissions of the repo were whanged
As a result, there was a diff in the repo, making it un-upgradable
After this commit, the permissions on the posbox' Odoo repository are unchanged, and no diff is to be seen
Before this commit, the latest version of Raspbian was chosen.
It is not very helpful though as if something goes wrong, we don't on which part it is.
Also, fix python dependencies for the image
When using Wi-Fi the Odoo instance on the POSBox will start after a
Wi-Fi connection is established. This takes a bit longer than when
you're using a wired connection. If Firefox gets started before you
end up with a 'Could not connect to localhost:8069' error.
A rounding issue was resolved in
ee33593351. It however introduced
another issue.
Rounding functions (both round_precision in web.utils and float_round
in openerp.tools) are not perfect due to IEEE floating point
limitations. However both should produce the same output given the
same input. An example: rounding 13.95 to 2 digits yields
13.950000000000001.
The additional rounding introduced in
ee33593351 on price lead to issues in
certain cases. One example occurs when applying a 90% discount on a
product costing 13.95. The POS will do the following:
> 13.950000000000001 * 0.09999999999999998
1.3949999999999998
> round_pr(1.3949999999999998, .01)
1.4000000000000001
whereas the backend will do (as eg. in sale.order.line)
>>> 13.95 * 0.09999999999999998
1.3949999999999996
>>> round(1.3949999999999996, 2)
1.3900000000000001
Causing a difference of 0.01.
The core of the issue is that in the backend 13.95 is rounded
differently. When a Float gets written to the database doesn't just
pass through the regular float_round. It passes through
_symbol_set_float which truncates characters exceeding the precision.
This implements the same approach in the POS.

Closes#16119
This adds the hw_screen module which is responsible for receiving
rendered HTML from a POS client and sending it to a running Chromium
browser. This is done by sending Remote Debugging Protocol messages over
a WebSocket provided by Chromium. This allows hw_screen to evaluate
arbitrary JS. This is used to seamlessly (without flickering) update the
browser.
This also includes changes to the POSBox. X, Chromium and some
miscellaneous other programs were added. Functionality was added that
automatically displays a fullscreen, UI-less Chromium browser when the
POSBox starts up. This is accomplished through x_application.sh, which
gets executed only when a display is detected. After the browser starts,
it will display a specific screen until it receives the first order update
from a POS client.
Creates a public controller to be able to display the interface on an external
device not connected to the posbox (e.g. tablet)

The POS uses FastClick to circumvent the 300ms touch delay implemented
by browsers before a click event is fired. (Although this has since been
removed, probably we can get rid of this in the POS at some point as
well [1]).
The way FastClick works is simple: immediately fire a synthetic event
and block the one fired by the browser 300ms later.
Recently, browsers have started to only trust native events to trigger
default actions [2][3]. Chrome in particular has started not trusting
synthetic events since v53.
FastClick provides a solution for this with the needsclick class. It
will not interfere with events triggered on elements with this class.

- ngrok download URL has changed
- default kernel for raspbian image has changed and needs to match
- remove pre-existing git checkout to avoid conflicting
- wait a few seconds after setting up loop dev with kpartx to access image
contents - sometimes required to let the device appear in /dev
when extending these methods with the new api, the context is a frozendict
so we need to copy before mutating.
this patch was made by searching for key addition to context and calls to the
update() method on the 8.0 addons, and checking if a copy was made before in
the method.
