This change concerns reports of `qweb-html` type. Previously, they were
openned in a popup and it was not very practical. We chose to open these
reports in an iframe (as opposed to what's done in `account_report`) in
order to be the most close to the pdf version in terms of apperance.
The client action allows an integration with the control panel. Apart from
the breadcrumbs integration, we also add buttons to handle the web_editor
(save, discard, etc). We also add a button to print the pdf version.
As there is some security concern to communicate with an iframe, we use
the postMessage[1] technology and we fix the `targetOrigin` to the
`web.base.url` parameter, that means that if the window to which we send
the message does not match the `web.base.url` origin, the event is not
even dispatched.
In order to to that, the report module uses the ir_http `session_info`
override mechanism to add the `web.base.url` in the DOM of the webclient,
and the report module adds to the DOM of report the `web.base.url`
content. This way, both scripts (in the webclient and in the iframe)
have the information of the trusted origin.
The client action does not have a complicated logic: it opens the
report's url in an iframe to show the report or open the web_editor
(the editor is activated by using the `enable_editor` query string.
If you click on the control panel button (save/discard) it'll send
message to the web_editor in the iframe to ask for save and discard.
It also waits for messages to know if the edition is done / cancelled
and toggle buttons of the control panel accordingly.
To allow that, we override the web_editor mechanism if it's opened in
an iframe and we chain to the `save` and `cancel` method deferred that
send message to the client action's window. We also make the web_editor
waits for message to start and stop the edition (controlled by the
control panel buttons).
The override of the action manager has been refactored / improved in
order to open the clien action and not the popup anymore. This way
we are able to, in the client action, return the current action with
the type `qweb-pdf` and the report is downloaded.

PURPOSE
=======
I've seen this new improvement regarding the naming of the printed reports:
https://www.odoo.com/web?#id=10870&view_type=form&model=project.task&menu_id=3942&action=327
This makes the report have the pdf name being the name instead of the report_name of
the ir.actions.report.xml, which is already an improvement.
But why don't we allow the users to have their own naming conventions?
I mean, we could allow our client to create and name their pdf the way they want, as
they do regarding the attachment.
Not only when it's about saving it as an attachment on the record, but also when downloading
directly the pdf, such that the modification in the previous screenshot, would give the following
result when downloaded:
People need to have their pdf named automatically according to a convention. When you print 10 sales
order during an hour, you don't want to get lost in having the following:
Devis / Commande.pdf
Devis / Commande(1).pdf
Devis / Commande(2).pdf
Devis / Commande(3).pdf
Devis / Commande(4).pdf
Devis / Commande(5).pdf
Devis / Commande(6).pdf
Devis / Commande(7).pdf
especially when those are for different partners.
Up to this revision, barcodes set in reports are generated
using the controller `/report/barcode`,
using a `img` HTML tag, e.g. (from `report_location_barcode`)
```
<img t-if="not o.loc_barcode"
t-att-src="'/report/barcode/?type=%s&value=%s&width=%s&height=%s'
% ('Code128', o.name, 600, 100)" style="width:300px;height:50px"/>
``
This `/report/barcode` route is set as `auth='user'`, meaning
the route can only be accessed by signed in users.
When wkhtmltopdf prints a report containing such a barcode,
it calls this `report/barcode` route, making sure to pass
the request session in the cookies, so wkhtmltopdf
uses the same session than the one of the user. This is
needed, as only users can access this `report/barcode/` route.
This session is passed in `report.py`, in the method
`_run_wkhtmltopdf`, thanks to the --cookie wkhtmltopdf
parameter.
Nevertheless, if a report is printed through the website
front-end, as public (without a signed in user), the request
session is not associated to a signed in user, and therefore
the route `/report/barcode` refuses the access / redirects
to the login, making it impossible to print a report
containing a barcode without being signed in. This even
if the report is printed as `sudo` through a controller
(as this is the session of the not signed in user which is passed,
not a session associated to `sudo).
Fixes#10621
opw-667797
Added two dummy reports to print an empty internal and external report
and added direct link to edit header/footers template in the form view
(in technical features) for convenience.
Also moved the 'preview rml report' under the rml configuration and
tried to make the company form as clean as possible but i think it's
failed.
