Add support for quota permission context request.

Add support for quota permission context request.

A patch branch for chromium is needed for that change:

https://git.launchpad.net/~abreu-alexandre/oxide/+git/chromium/commit/?h=expose-frame-id-quota&id=21f76382023aab780d211d5efad3c35690fc8ddc

[Chris Coulson (chrisccoulson)]

Thanks for working on this. I've added some comments inline.

This is also lacking tests - I'd start by looking at the geolocation permission tests (and also take in to consideration the points in bug 1399196). Note, cancellation when navigating subframes probably won't work for quota permissions like it should for geolocation (we have no indication of the frame on the browser side).

[Chris Coulson (chrisccoulson)]

I've added some comments inline for this

review: Needs Fixing

[Chris Coulson (chrisccoulson)]

I've left some comments inline again.

Also, how does this API behave if a site requests persistent storage in an incognito webview?

review: Needs Fixing

[Chris Coulson (chrisccoulson)]

I've left some comments inline.

And the tests are still missing quite a few cases:
- It's not testing if requests from subframes behave correctly.
- It doesn't test if requests are cancelled on navigation.
- It doesn't verify that the request is denied if the application ignores it (ie, QuotaPermissionRequest is deleted without a response).

I still don't know what happens if a page in an incognito webview requests a persistent storage quota. Did you find out?

[Alexandre Abreu (abreu-alexandre)]

created a expose-quota-frame-id branch in ~oxide-developers/oxide/+git/chromium to track the patches that add the frame id to the storage quota request,

Use Qt::PrimaryOrientation rather than passing in QScreen's own primary orientation

[Alexandre Abreu (abreu-alexandre)]

Also about you question, for incognito webviews the request still goes through except that for those the maximum quota is set to a lower threshold, see:

https://git.launchpad.net/~oxide-developers/oxide/+git/chromium/tree/storage/browser/quota/quota_manager.cc#n51

and

https://git.launchpad.net/~oxide-developers/oxide/+git/chromium/tree/storage/browser/quota/quota_manager.cc#n320

which is the control flow for a regular storage quota request with the case of a webview being incognito being handled as a max threshold case.

QCoreApplication::applicationName() isn't really thread-safe - cache it to protect against accessing this whilst the application is modifying it (although we don't really expect this to change)

Build with 'use_ash: 0' as this seems to be pulling in dependencies from //chrome, resulting in random mis-builds

Bump Chromium rev to 0fcc1746 (48.0.2564.22)

1287. By Chris Coulson on 2015-12-09

Add support for the camera on the phone. Note this requires changes to libhybris that aren't approved yet, so some bits may change. It's also hidden behind a build option (ENABLE_HYBRIS_CAMERA)

1288. By Chris Coulson on 2015-12-11

Don't require libhybris-dev to be installed when building without ENABLE_HYBRIS_CAMERA

1293. By Chris Coulson on 2015-12-22

Don't build qt/core/api in a separate target with different build options. This means we can stop linking unconditionally with --gc-sections. It also means that the public API no longer has RTTI enabled - if we need this in the future, we'll have to split it out again and plumb it through a proxy layer like we do with qt/quick/api

Don't include .git/index files anywhere in the tarball. This was added way back in r640 but doesn't actually fix anything, and instead causes LP: #1490868 to be reintroduced in official builds where we don't install git

Make a few changes to the build system:
- package is renamed to test-package, as the former is a reserved target in cmake. This gets rid of a warning.
- Use the built-in option command.
- Move a bunch of stuff from qt/CMakeLists.txt to CMakeLists.txt
