Bug ID: 40672
           Summary: wine-gecko cannot do xml + xslt on-the-fly transform
                    and display, ie8 can.
           Product: Wine
           Version: 1.9.0
          Hardware: x86
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: mshtml
          Assignee: [e-mail]

While switching the Font Validator code from COM interop with IE to managed
System.Windows.Forms.WebBrowser
( https://github.com/HinTak/Font-Validator/blob/master/FontVal/ResultsForm.cs )
to better support linux mono, and testing under wine for regressions, I
remember having problems with all the various combinations on a clean
wineprefix - stock wine (i.e. wine-mono), dotnet2 plain, dotnet2 + ie6, + ie7,
+ ie8 - except dotnet2 + ie8 .

Later I worked out that dotnet2 + ie7 and dotnet2 + wine-gecko would happily
display html, just not do xml + xslt on-the-fly transform, which was how the
code was originally written (see the history of the above file), hence I now
work around the wine problem and moved on.

Another part of the original FontValidator requires genuine dotnet2 (mixed mode
assemblies, does not work under wine-mono), but it would be good for wine-gecko
to be able to do xml + xslt displays like ie8 does.

Unfortunately I currently tried to detect wine by looking for WINEPREFIX in the
environment (line 123 of
https://github.com/HinTak/Font-Validator/blob/master/FontVal/ResultsForm.cs ),
but you can probably

The pre- COM->managed binary:

https://sourceforge.net/projects/hp-pxl-jetready/files/Microsoft%20Font%20Va...

the post- COM->managed binary:
https://sourceforge.net/projects/hp-pxl-jetready/files/Microsoft%20Font%20Va...

To test, just fire it up, go to File->Open XML report-> and just load any local
web pages, or xml + xslt combo.

Note the dependence on  https://bugs.winehq.org/show_bug.cgi?id=30988 - you
need genuine dotnet2 to have any embedded webbrowser capability at all -
wine-mono is insufficient. This bug is about wine-gecko vs ie8 on top of
dotnet2.

I did the FontVal change around the new year, found work-around and moved on,
hence the 1.9.0 tag. It probably affects later versions of wine.

The details are a bit hasty now, but I remember vaguely that dotnet2 + ie6 does
not work with either xml + xslt or html, dotnet2 + ie7 works only with html,
and dotnet2 + ie8 works with both; after discovering that  dotnet2 + ie7 works
only with html, I went back and tested dotnet2 + wine+gecko, hence the current
workaround.

Font Validator is a microsoft technology, so once I found one combo - dotnet2 +
ie8 - that works as good as genuine windows, and added the small wine detection
to supports also dotnet2 + ie7 and dotnet2 plain (i.e. + wine-gecko), I moved
on. On hind-sight, I probably should not have the work-around, so I am thinking
of reverting/removing that particular part of the code in
https://github.com/HinTak/Font-Validator/blob/master/FontVal/ResultsForm.cs .

Does the bug still occur with wine-6.19?

AFAIK it is not a code bug, but a security policy - neither gecko nor
webkit/blink (chrome family) of web browsers would load xslt from disk, as a
matter of default security policy.
