Most common winetest failures on wine

[Dan Kegel]

Thanks to everybody who responded to Jeremy's call
to run winetest using the 'dotests' script at
   http://wiki.winehq.org/MakeTestFailures

We now have 35 reports, and have some good data on
which test failures are common.  See the
Most Common Failures section at the bottom.
Here's what it says right now:

The skipgood script above now also tallies tests by how many people
they fail for. Currently, it shows:

35 shell32:shelllink
32 user32:msg
16 user32:input
14 ntdll:info
13 d3d9:visual
10 user32:win
8 ddraw:visual
7 urlmon:protocol
5 gdi32:font
4 winmm:wave
3 d3d9:query urlmon:url wininet:url
2 comctl32:tooltips ddraw:dsurface msxml3:domdoc quartz:referenceclock
wininet:http
1 d3d8:visual d3d9:device dinput:device dsound:ds3d dsound:ds3d8
dsound:dsound ...

Let's ignore the tests that only fail for one person for the moment,
and look at the others.

shell32:shelllink fails on all winetest reports from all machines,
including on real Windows. Yet "make test" in shell32 succeeds on this
test. Could somebody have a look at why it reliably fails under
winetest? I filed this as bug 13311.

user32:msg and user32:input are probably people running non-blessed
window managers; Alexandre's position is that we can ignore these,
since upstream gnome's WM is fixed.

ntdll:info is a flaky test marked todo_wine that succeeds sometimes:
"info.c:822: Test succeeded inside todo block: Expected to read 0
bytes, got 0"

d3d9:visual failures are all from people not running an approved
graphics card, and can be ignored (though maybe we should tell users
we only support nvidia Geforce 6 and higher for 3d graphics...)

user32:win appears to be nearly all people running unapproved window
managers, though abraml-hardy-32 did get one failure "win.c:2555: Test
failed: wrong active window (nil)" with KDE3 which should be
investigated. [fixme: file bug?]

ddraw:visual has two kinds of errors. The most common is
"visual.c:2045: Test failed: Got color 00dcdde6, expected 0000ff00".
Less common is mstefani's failure, "visual.c:481: Test failed:
Untransformed vertex with linear vertex fog has color 00ff0000".
[fixme: file bugs?]

urlmon:protocol has three or so failure modes; most common is
"protocol.c:1597: Test failed: Read failed: 8000000a (0 bytes)".
[fixme: file bug?]

gdi32:font has several failure modes, not sure what's going on there.
[fixme: file bug?]

winemm:wave might actually be a problem, perhaps Maarten can take a
look. [fixme: file bug?]

I haven't looked at the failures that happen for only 2 or 3 people.
