NT4: ==== No failures.
Is there another way you can detect whether some XP (and up) tests can be run? We generally try not to use GetVersion() in our tests.

Just a guess, but XP's screen color depth of 32bpp might be significant here. If that's the case you'd also expect the tests to fail on an XP machine configured to e.g. 24bpp.

NT4:
No failures.
Is there another way you can detect whether some XP (and up) tests can be run? We generally try not to use GetVersion() in our tests.
Thanks for the quick response Paul. I'll look into the problem and resend.
I've run your new tests on Win95, Win98 and NT4 (all VMware):
Is there another way you can detect whether some XP (and up) tests can be run? We generally try not to use GetVersion() in our tests.
It turns out that the reason for the Win95 errors is that it calculates true-colour -> 16-bit dithers differently. These tests can be safely skipped, on these platforms.
In addition to the errors Win95 has, the other Win98 failures seem to be the product of my interpretation GetVersion returns being wrong. Easily fixed.
However, you're saying GetVersion is a problem. Why is that? And how else is one supposed to cope with GdiAlphaBlend not being present in pre-XP systems, as well as old-style dithering differences?
Thanks Joel

Hi Joel,
GetVersion() is not a problem in itself but we make an effort to decide what to test based on behavior not version. If it absolutely can not be avoided (and you will see some examples in the code) GetVersion() is accepted.
You reference GdiAlphaBlend(). That's not part of user32. If you are sure Windows uses this for alpha blend support you can always check for the availability of the GdiAlphaBlend() function:
static BOOL (WINAPI *pGdiAlphaBlend)(HDC,int,int,int,int,HDC,int,int,int,int,BLENDFUNCTION);
pGdiAlphaBlend = (void*)GetProcAddress(GetModuleHandle("gdi32.dll"), "GdiAlphaBlend");
if (!pGdiAlphaBlend) { We are on W95/W98/WinME/NT4 }
This will give you a chance to decide not to run the tests on these platforms. I already ran you tests on NT4 and they pass. This doesn't mean that all tests run on NT4 as you sometimes return() without having done an ok() test or with a trace() or skip()/win_skip(), like here:
+ hicon = create_test_icon(hdc, 2, 1, bpp, 0, (UINT32*)&color, sizeof(color)); + if (!hicon) return;
Is there a reason this could fail? If not you should add an ok() test for hicon. If yes, you should use skip() or win_skip() to show these tests are skipped but with a correct/expected reason.
There are more of these "blind" return's in your patch.

I think this is the case here. DrawIcon[Ex]'s behaviour has evolved over time, but we want Wine to support the modern behaviour not the 9X behaviour.

Sorry - that was a mistake in my earlier e-mail. The version of Windows that introduced GdiAlphaBlend also introduced alpha-channel rendering in DrawIcon[Ex] as well (which must use GdiAlphaBlend internally). So in this case it would be better to check version numbers not check for the presence of GdiAlphaBlend, because that's not what I'm testing.

Ok - yes these can be fixed. I did the blind thing because I've noticed other tests do that for the error condition, and I figured that my tests don't want to test CreateIcon et al; these are already tested. I'm only testing DrawIcon[Ex], but I suppose extra tests can't hurt.

My main idea about those return's is that I thought that they could maybe be used to show behavior that could have been used to decide whether tests can be run.

Wine tests try to not depend on a particular OS version but instead cope with differences in APIs directly. For new APIs not present in earlier OSes this is simple. You need to import them dynamically anyhow in order to not cause the entire test module load to fail on older OS versions.
It is then simple to test for a valid function pointer from GetProcAddress() und skip all relevant tests if this is not the case.
Other differences should probably be handled by allowing either result to be valid and considered as a success for that particular operation. Same as with testing error return values for instance where sometimes a range of error codes is accepted as valid result.
