Bug 74519 – [Qt] Automatic clean build feature always do clean build with --no-webkit2

• Status: RESOLVED
• Resolution: FIXED
• Component: Tools / Tests

[Csaba Osztrogonác]

I have no idea why, but every build is clean build with --no-webkit2 option:
Feature PLUGIN_ARCHITECTURE_UNSUPPORTED was removed, clean build needed!

[Csaba Osztrogonác]

Additionally with --no-webkit2 WEBKIT_TESTFONTS feauture
landed in http://trac.webkit.org/changeset/102776 doesn't work,
but it work's with Qt5-WK1 if we don't use --no-webkit2.

[Csaba Osztrogonác]

I removed --no-webkit2 from our Qt5-WK1 bot config temporarily. I'll check this bug tomorrow.

[Tor Arne Vestbø]

Cool, let's look at it tomorrow.

[Csaba Osztrogonác]

Maybe it is related to http://trac.webkit.org/changeset/99872
I hope http://trac.webkit.org/changeset/103058 fixed it.

But we I'd like to leave this bug open for several days to make sure if it is fixed.

[Csaba Osztrogonác]

Now the problem is worse. run-javascriptcore-tests call build-jsc which always triggers a clean build, but build-jsc builds only jsc and it broke layout and API tests.

Running: build-jsc --qt --release --32-bit --qt
Feature PLUGIN_ARCHITECTURE_UNSUPPORTED added, clean build needed!

I disabled --no-webkit on the Qt5-WK1 bot again.

[Csaba Osztrogonác]

This bug is still valid, you can reproduce it easily:
- Tools/Scripts/build-webkit --no-webkit2
- Tools/Scripts/run-javascriptcore-tests

The root of the problem is that build-webkit pass the BUILD_WEBKIT_ARGS environment: --no-webkit2 to qmake as --qmakearg=CONFIG+=no_webkit2,
but build-jsc doesn't. And the problem is that webkit2 build contains PLUGIN_ARCHITECTURE_UNSUPPORTED define, but --no-webkit2 build doesn't.

Modifications in build-webkit, build-jsc, webkitdirs.pm

I ran Tools/Scripts/build-webkit --no-webkit2 and then Tools/Scripts/build-jsc with this patch.
Probably it fixes the problem, but it is not final yet.

I think this patch is way to intrusive for what it does. 

I see a few options: 

  - Set BUILD_WEBKIT_ARGS on the bots for all processes, not just when running build-webkit. Since build-jsc or run-javascriptcore-tests will potentially build webkit, BUILD_WEBKIT_ARGS should be set for those as well.

  - Make build-webkit do a pure build and not a reconfigure as well when called without any arguments (or from another script), so that if you do build-webkit --no-video, and then call build-webkit, it would just build and not complain about video now being enabled. 

  - Set the PLUGIN_ARCHITECTURE_UNSUPPORTED define to something, even when not building webkit2.

or some combination of these.

Thank you for the comments, I will try to find a less complicated solution with the help of options you have mentioned.

Modifications in the build-system

I took Tor Arne Vestbø's advice, the patch always set PLUGIN_ARCHITECTURE_UNSUPPORTED define.

Adding it to build-webkit makes no sense at all. This should be a features.prf change only. And you put a no_webkit2: PLUGIN_ARCHITECTURE_UNSUPPORTED=1 block at the start and add a comment that the reason we're doing that is because of this bug.

I do not understand why merging conflict caused in skiplists, the patch did not deal with them. Whatever I have cleaned my repo and redo all the modifications.

"it's needed"

I'd write this (along with the lines below) as

!contains(DEFINES, PLUGIN_ARCHITECTURE_UNSUPPORTED) {
    no_webkit2 {
        # --no-webkit2 build did not contain this define, but it's needed to avoid unwanted clean builds by other scripts
        DEFINES += PLUGIN_ARCHITECTURE_UNSUPPORTED=1
    } else {
        # The old block
    }
}

Thank you for the advice, under a new bug there will be a more general solution for plugins that missing from no-webkit2 build.
