Remove qtwebkit from touch image

The current use by 20 apps in the store:
 - 2 apps that cannot be ported as of today
 - one app that would require a sizeable amount of work
 - one app that would require some work
 - 5 apps that would require minimal changes
 - 11 apps that wouldn’t require any changes (other than the imports)

(9) no specific QtWebKit API used, can be replaced by Ubuntu WebView without any changes:

  com.ubuntu.developer.carloalberto.randomimagesrel
  com.ubuntu.developer.fabricio.mnmo-counters
  com.ubuntu.developer.hansueli.burri.xkcd-viewer
  com.ubuntu.developer.larochelle.brian.feed-the-aggregator
  com.ubuntu.developer.mlosli.panpipe
  com.ubuntu.developer.mzanetti.getmewheels2
  com.ubuntu.developer.yuntan.aztter
  ir.oneapp.oneperday

(2) actually uses an UbuntuWebView (version 0.1), can be replaced by Ubuntu WebView without any changes
  com.ubuntu.developer.mzanetti.ubuntu-fitbit-app
  com.ubuntu.developer.rschroll.beru

(4) uses WebView.onLoadingChanged, minimal changes needed
  com.nucleussystems.app.freshbookstimer
  com.ubuntu.developer.mitya57.touchwriter
  com.ubuntu.developer.qqworini.aesyweibo
  com.ubuntu.developer.qtros.twimgo

(1) uses onLoadProgressChanged, but can easily be rewritten to avoid that
  fr.skimbo.skimbou

(1) relies on the fact that QtWebKit’s WebView is a flickable, shouldn’t be too hard to port to Ubuntu WebView
  com.ubuntu.developer.brianrobles204.karma-machine

(1) uses lots of QtWebKit experimental APIs (it’s a browser app), sizeable amount of work to migrate to Ubuntu WebView (or more likely a raw Oxide WebView)
  com.ubuntu.developer.penk.slatekit-shell

(2) uses QtWebKit experimental APIs such as urlSchemeDelegates, cannot be replaced by Ubuntu/Oxide WebView as is
  com.ubuntu.developer.dpniel.dekko
  com.ubuntu.developer.zaspire.cordova-mobilespec

Bug 1260016 added for an API to allow defining custom URL scheme delegates

We need to remove the dependency from the html container, which depends on Oxide 1.3 which supports script injection.

We also need to update all webapps using a policy < 1.1
There are 24 such apps in the store

The bug to add script injection to oxide for use in the html container is bug #1221996

This may not make rtm and isnt critical

opened a webbrowser-app task to track if there is any work needed on the browser or container side to remove this dependency. please mark invalid if not.

I installed all 624 apps from the store (as of today) on a Nexus 7 running vivid-proposed (image #42), and grepped through them to get a picture of which still use QtWebKit. Here’s a summary:

 - 15 applications import (and supposedly use) QtWebKit directly:

    com.nucleussystems.app.freshbookstimer
    com.ubuntu.developer.brianrobles204.karma-machine
    com.ubuntu.developer.carloalberto.randomimagesrel
    com.ubuntu.developer.fabricio.mnmo-counters
    com.ubuntu.developer.hansueli.burri.xkcd-viewer
    com.ubuntu.developer.larochelle.brian.feed-the-aggregator
    com.ubuntu.developer.mitya57.touchwriter
    com.ubuntu.developer.mzanetti.getmewheels2
    com.ubuntu.developer.penk.slatekit-shell
    com.ubuntu.developer.qqworini.aesyweibo
    com.ubuntu.developer.qtros.twimgo
    com.ubuntu.developer.yuntan.aztter
    com.ubuntu.developer.zaspire.cordova-mobilespec
    fr.skimbo.skimbou
    ir.oneapp.oneperday

 - 10 applications import (and supposedly use) Ubuntu.Components.Extras.Browser 0.1, i.e. QtWebKit under the hood:

    com.ubuntu.developer.andrewsomething.stackbrowser
    com.ubuntu.developer.daker.bytesjack
    com.ubuntu.developer.daker.x-type
    com.ubuntu.developer.fcole90.feedspot
    com.ubuntu.developer.karthik.upadya1.ifacebook
    com.ubuntu.developer.karthik.upadya1.igplus
    com.ubuntu.developer.karthik.upadya1.imail
    com.ubuntu.developer.mdspencer.project-dashboard
    com.ubuntu.developer.sangshuduo.doubanfmunofficial
    com.wellsb.esv-bible

 - 4 applications import Ubuntu.Components.Extras.Browser 0.2 (i.e. Oxide under the hood), they could use a rename of the import to Ubuntu.Web 0.2:

    com.ubuntu.developer.alaak.uberbag
    com.ubuntu.developer.filip-dobrocky.gagger
    com.ubuntu.developer.karthik.upadya1.wikipediatouch
    com.ubuntu.developer.rschroll.beru

 - 16 applications import Ubuntu.Web 0.2 (i.e. Oxide under the hood), no change needed:

    com.canonical.payui
    com.ubuntu.developer.bobo1993324.pdfjsviewer
    com.ubuntu.developer.mhall119.ureadit
    com.viclog.2048
    com.ubuntu.developer.bobo1993324.udropcabin
    com.ubuntu.developer.danielholm.pingpong
    com.ubuntu.developer.dholbach.randomcats
    com.ubuntu.developer.mdspencer.project-dashboard
    com.ubuntu.developer.mlosli.panpipe
    com.ubuntu.developer.mzanetti.ubuntu-fitbit-app
    com.ubuntu.developer.qtros.yad
    com.ubuntu.developer.rayalez.hackernews
    com.ubuntu.developer.roman2861.zmusic
    com.ubuntu.developer.turan.mahmudov.ufoursquare
    com.viclog.flappybird
    cx.gould.ted.ubuntu-app-startup

 - 12 applications import com.canonical.Oxide, no change needed:

    com.ubuntu.reminders
    com.popey.calculator
    com.popey.sst
    com.ubuntu.developer.danielholm.stumble
    com.ubuntu.developer.dobey.delta-web
    com.ubuntu.developer.dpniel.dekko
    com.ubuntu.developer.mkamenjak77.4chanappextra
    com.ubuntu.developer.mkamenjak77.bluedragonbrowser
    com.ubuntu.developer.mkamenjak77.bugapp
    com.ubuntu.developer.mkamenjak77.googleplusapp
    com.ubuntu.developer.nathanosman.twobuntu-app
    com.ubuntu.developer.rschroll.beru

 - Additionally, there are still 15 webapps using version 1.0 of the policy, ...

All the apps that still use QtWebKit (either explicitly or through Ubuntu.Components.Extras.Browser 0.1 or version 1.0 of the policy) should be rather straightforward to migrate to Oxide with minimal changes, without any work required in webbrowser-app.

There are two exceptions, which might not be that easy to port (if possible at all, assessing that would require in-depth analysis of their code):

    com.ubuntu.developer.penk.slatekit-shell
    com.ubuntu.developer.zaspire.cordova-mobilespec

Leaving the webbrowser-app task open as the webapp container is currently built with QtWebKit support (for web applications that still use version 1.0 of the policy). Once those applications are updated to use version 1.1 of the policy, we can remove QtWebKit support, and a lot of conditional code with it.

For webapp-container, ie webapps, I have sent emails to the maintainers of all the 20 webapps still using the 13.10 framework.

As of today, we have 8 of them already updated to 14.04, and 12 still pending.

For the Cordova sample app, we should be able to upload a new version shortly with the new cordova release which now supports Oxide directly.

Keep in mind also that you can't transparently migrate apps to Oxide, because of the framework they are attached to. Apps still using the 13.10 framework will need an explicit upload, as the apparmor policy will only let them use Oxide if they declare 14.04+ and add the 'webview' policy_group. I counted 120 apps still using 13.10, out of which 20 are webapps.

Pushing out due to all the moving pieces

make it part of move to vivid

On latest vivid, the following binary packages still depend on libqt5webkit5, making it stay on the image:

signon-ui-x11 (signon-ui): libqt5webkit5
ubuntu-html5-container (ubuntu-html5-theme): qml-module-qtwebkit
webapp-container (webbrowser-app): qml-module-qtwebkit
qtdeclarative5-ubuntu-ui-extras-browser-plugin (webbrowser-app): qml-module-qtwebkit
ubuntu-sdk-libs (ubuntu-touch-meta): qml-module-qtwebkit

The Cordova runtime has been updated to only use Oxide.

As of today, com.ubuntu.developer.daker.x-type has been updated to use Oxide.

For reference all published webapps have been migrated to the newer framework which uses Oxide:
- the upload of new webapp mandates the use of the Oxide-oriented frameworks for a few months
- developers have been informed of the change on the ubuntu-phone mailing list
- developers of webapps requiring a framework upgrade have been contacted individually and guided to upload updated click packages

What is left before this can be removed?

All of comment #15 is still valid: signon-ui, ubuntu-html5-theme and webbrowser-app need to stop using/depending on it.

I'll propose a branch against the seed to remove that depedency.

This bug was fixed in the package ubuntu-touch-meta - 1.216

The meta package update means webkit would drop from the images if the three remaining source packages would stop depending on it in the binaries installed on device.

Adding signon-plugin-oauth2 task, since it erroneously depends on now dummy package signon-ui, which Recommends signon-ui-x11, which is not needed on the images but brings the webkit dependency. Neither signon-ui-x11 or signon-ui dummy package should be on the phone images.

Correction: not Recommends, but Depends: signon-ui-x11 | ubuntu-system-settings-online-accounts (>= 0.4) - however, since signon-ui-x11 is listed first, and it does not conflict with u-s-s-o-a, it gets installed.

Removing signon-ui. The fix will happen on the signon-plugin-oauth2 project.

Removed from image #172 onwards:

http://people.canonical.com/~ogra/touch-image-stats/172.changes

Space savings from those four dropped packages: 380 + 614 + 500 + 22739 = 24233kB.
