Bug 57068 – [GTK] [WebKit2] Implement a basic WebKitTestRunner

• Component: WebKitGTK
• Status: RESOLVED FIXED

[Martin Robinson]

WebKitTestRunner is required to run tests on WebKit2. We should work much more on WebKit2 without it.

While calling g_object_set() again? you can just add "gtk-xft-rgba", "none" to the first g_object_set call.

isn't this function X11 specific?

Ah, right, this should move up into the previous block. For a particular test it needs to move, but I'm not sure if it's possible to get the test name at this point in the file.

It's specific to ports that use FontConfig. As far as I know we are phasing out non-FontConfig builds.

Great Patch :)

Are these Prefix headers now required to be included in makefiles since we are including config.h anyways in all files as first header?

Why do we require WINMM libs for GTK port?

Instead of listing all fonts, can we use the env variable WEBKIT_TEST_FONTS, which is used in DRT as well as other WebKit2 ports? It simplifies the code here a lot.

Can we name it as waitToDumpWatchdogTimerFired() itself?

Shouldn't this be FALSE? Who will cancel it since it will be firing continuously?

Why are we not using gtk_widget_set_size_request() since it does both window_resize & size_allocate?

Ditto.

Shouldn't the cancelTimeout() here based on the bool condition sent in platformRunUntil()? All other ports run until the bool goes false on which they cancel the timer. Isn't it so?

Looks good, still checking what happens and why it stalls when starting to test, but somme comments already.

Apparently gdk_window_get_geomtry does not include depth as a parameter in gtk+3.

I think it's good to set up the prefix header even if it isn't strictly necessary now. It might be useful later and we want the ports to be as similar as possible.

> > Tools/WebKitTestRunner/GNUmakefile.am:44

This is required for GTK+ builds on Windows. Perhaps this could be moved to the library itself, but that should happen in another patch.

It's possible that we could move some of this to a helper function and compile it into both the DRT and the WKTR, but some of it must still be different. I'd prefer to have as much of the logic be in the harness rather than the harness-script (old-run-webkit-tests), since we have to write it twice (for new-run-webkit-tests as well).

I've renamed this to waitToDumpWatchdogTimerCallback to simplify things. I prefer having the "Callback" suffix on GSignal callbacks to be more precise. :)

It should! Fixed.

The documentation for gtk_widget_set_size_request says "Sets the minimum size of a widget; that is, the widget's size request will be width by height. "

The Qt port ignores the boolean parameter as well. I think it's just a nicety for ports that work more like the Mac port where the main loop runs directly in the platformRunUntil method.

I've #ifdeffed this section for GTK+ 3.x. Nice find.

Can't we define both the typedef here itself instead of 2 separate blocks?

I guess the argument should be WKImageRef. :)

I'm surprised the :: is needed.

Do we need to close this ever?

This doesn't look right. You should modify buildPlatformHierarchy instead, similar to what is done for win-wk2 and mac-wk2.

Do you want to modify readSkippedFiles, too, to fall back to mac-wk2 like win-wk2 and qt-wk2 do?

This seems somewhat orthogonal.

Is it not possible to find the injected bundle using a path relative to the test runner?

I think you're leaking m_injectedBundlePath.

You could assert that m_injectedBundlePath is initialized.

Thank you very much for the review! I've attached an updated patch.

Sadly, it is. Attempts to remove it have been unsuccessful.

Closing the module will make the symbols unavailable. It stays open much like the Mac implementation. It seems that the lifetime of InjectedBundle is for the extent of the WebProcess?

I think we are still exploring how our test situation looks.  Hopefully we can share the skipped list in the future like the Qt port.

I added because the old-run-webkit-tests script executes run-launcher to show the results. Right now this produces an error because we build WebKit1 separately. In the future we'd like to build them together, so maybe this change is not needed in the end. It can certainly be in a separate patch though. I've removed it.

It's actually non-trivial to find the binary path in a cross-platform way. We've punted on this, much like Qt.

> I think you're leaking m_injectedBundlePath.

You're right! I've fixed it in my patch and I will try to write a patch to fix the Qt code.

I'd write this as a one-liner: return $library if -e $library;

This won't do the right thing if $productDir contains a space and @ARGV is empty. (The shell will split $productDir on the space and try to execute a bogus path instead of WTR.) One way to avoid that is:

my @args = ("$productDir/Programs/WebKitTestRunner", @ARGV);
return system { $args[0] } @args;

You could use an early continue instead of nesting code inside this if.

This needs braces because it is multiple lines (even though it's only a single statement).
