Bug 72947 – [Qt] Add support for using OWRT with Qt5

• Component: Tools / Tests
• Status: RESOLVED FIXED

[Csaba Osztrogonác]

It seems -graphicssystem command line argument isn't supported by Qt5:
// ### Qt4 compatibility, remove?
static inline void setGraphicsSystem(const QString &) {}

But ORWT still pass this argument (-graphicssystem raster) to QtTestBrowser,
and QtTestBrowser open an empty window with URL-bar: http://raster and "Host not found" text.

We shouldn't pass "-graphicssystem raster" argument if Qt version >= 5.

I think the idea is good. The ChangeLog entry is missing and I have a few nitpicks :)

> +        $platform = "qt-5.0";

This seems unrelated?

> Tools/Scripts/old-run-webkit-tests:1222
> +  if(!(getQtVersion() ge "5.0")) {

Shouldn't that properly check the major version of Qt only? (if major-version < 4)

No, we need this change too, because qt-5.0 platform wasn't supported by ORWT before.

Of course we can check only the major version, but getQtVersion() (webkitdirs.pm)
parses qmake's output and return major&minor version in this format as string.

I think, that if ((getQtVersion() lt "5.0")) would be good, because 
it is equivalent to (non-existent-yet) (getQtMajorVersion() < 5).

It looks like your first name isn't properly utf-8 encoded here. Is that possible?

> Tools/Scripts/old-run-webkit-tests:242
> +    } elsif (getQtVersion() eq "5.0") {
> +        $platform = "qt-5.0";

This looks like an unrelated change. Is that intentional?

This looks much better :). Out of curiosity: Does 'lt' work with strings like "5.0" like that?

Ooops, I didn't see Ossy's comment. Let me see again :)

Shouldn't this be mentioned in the ChangeLog then?

Right now the title of the bug is about not passing -graphicssystem raster when running OWRT with Qt 5. I do however have the impression that the title of this bug should be "Add support for using OWRT with Qt 5" or similar, and that the ChangeLog should mention this line.

I think pretty diff can't handle correct the utf8 names.
Check one of my patches: https://bugs.webkit.org/attachment.cgi?id=114235&action=review
or one of Tor Arne's patches: https://bugs.webkit.org/attachment.cgi?id=104833&action=review

Unfortunately perl differs from bash. lt, eq, gt, ... are for string comparision in perl.

You're right, we should.

It's reasonable, I fixed the title of the bug.

LGTM, r=me.

> +  if(getQtVersion() lt "5.0") {

only a little nit: missing space after the if.(I'll fix it locally before landing.)
