Merge ~osomon/oxide:autofill into oxide:master

[Olivier Tilloy]

Add support for autofill popups in UbuntuWebView (LP: #1214048).

This initial implementation supports single text fields, datalist entries and autofill profiles.
Credit cards and passwords are not supported.
There is no API to manage stored profiles, this will be implemented as a followup feature.

8f3dace... by Olivier Tilloy on 2017-02-28

Fix a unit test when run in single process mode.

acc726e... by Olivier Tilloy on 2017-03-10

Reduce the height of the autofill entries.

2bf8c7c... by Olivier Tilloy on 2017-03-10

Preview autofill entry under mouse cursor.

fca284a... by Olivier Tilloy on 2017-03-10

Highlight currently selected suggestion.

32f4f1e... by Olivier Tilloy on 2017-03-13

Simplify focus handling.

0fd49b9... by Olivier Tilloy on 2017-03-13

Fix FTBFS.

305a4b1... by Olivier Tilloy on 2017-03-13

Handle validation when no suggestion is selected.

c6f3be8... by Olivier Tilloy on 2017-03-14

Add a unit test for autofill popup destruction.

ff81c57... by Olivier Tilloy on 2017-03-15

Ensure unit tests are locale-independent.

[Chris Coulson (chrisccoulson)]

I haven't had time to complete the review of this yet, so I've left you a few comments in the meantime to unblock you :)

review: Needs Fixing

[Chris Coulson (chrisccoulson)]

I've left a few more comments now. I've not yet finished reviewing it though, so there will most likely be some more later.

review: Needs Fixing

f7170cf... by Olivier Tilloy on 2017-03-23

Fix build errors when rebased on latest master.

12ec53f... by Olivier Tilloy on 2017-03-23

Always use an InMemoryPrefStore.

Persisting the value of OxideQQuickWebContext::autofillEnabled would be
inconsistent with every other setting exposed by the API
(eg, we don't persist popupBlockerEnabled or doNotTrackEnabled).

2c47ca7... by Olivier Tilloy on 2017-03-23

Move CreateAutofillPopup to WebContentsClient.

bd0082a... by Olivier Tilloy on 2017-03-23

Bump version for new WebContext API to 1.23.

b7f468f... by Olivier Tilloy on 2017-03-23

Drop default case as there's already a branch for every value.

579a028... by Olivier Tilloy on 2017-03-23

Do not modify oxide::ContentClient to access the application locale.

Instead, expose the application locale as a new method on BrowserPlatformIntegration.

e1aa089... by Olivier Tilloy on 2017-03-23

Marked a private helper private.

f0aa5a2... by Olivier Tilloy on 2017-03-23

Ensure that autofill works in incognito mode, as expected.

[Olivier Tilloy (osomon)]

I addressed the first round of comments from two days ago. Still pending: add tests for autofill behaviour in incognito mode.

1d7be1b... by Olivier Tilloy on 2017-03-23

Add tests for autofill in incognito webviews.

e48baae... by Olivier Tilloy on 2017-03-23

Make WebAutofillPopupHost::Init not return anything, for consistency.

4017f9d... by Olivier Tilloy on 2017-03-23

Remove redundant std::move().

4116cd7... by Olivier Tilloy on 2017-03-23

Rename methods to start with an uppercase letter, for consistency with newly-written code.

31d4425... by Olivier Tilloy on 2017-03-23

Take timeout into account.

dc3f850... by Olivier Tilloy on 2017-03-23

Do not depend on the omnibox component in release builds.

f4c8cba... by Olivier Tilloy on 2017-03-23

Rename files for consistency with newly-added code.

4fd1d34... by Olivier Tilloy on 2017-03-23

Remove unused references to gfx::NativeView (always null) in AutofillPopupController.

88dfc51... by Olivier Tilloy on 2017-03-23

Remove unused method.

31c9a11... by Olivier Tilloy on 2017-03-23

Make ownership of AutofillPopupController explicit.

[Olivier Tilloy (osomon)]

I addressed all comments (and answered questions) in the second review round except for the last one (the suggestion to re-implement a custom WebDataServiceWrapper), which is pending.

8dcafd5... by Olivier Tilloy on 2017-03-27

Fork WebDataServiceWrapper to remove bits that oxide doesn't need.

[Olivier Tilloy (osomon)]

WebDataServiceWrapper has been forked to remove all the bits that oxide doesn't need, thus removing the need for the dependency on omnibox in a component build.

bc34ffb... by Olivier Tilloy on 2017-03-27

New FilteredPrefStore class that stores all preferences in memory except for a selected set which are persisted on disk.

133ba6a... by Olivier Tilloy on 2017-03-28

Unit tests for FilteredPrefStore.

1ac8924... by Olivier Tilloy on 2017-04-17

Remove stale line that remained after rebasing on master.

Unmerged commits

1ac8924... by Olivier Tilloy on 2017-04-17
