Re: [ros-dev] [ros-diffs] [sginsberg] 36773: - Unbreak GetTextFaceA/W, broken since 28730 by GreatLord

[gedmurphy]

Why do you need to publically state it was broken and who broke it?
Does it make you feel more important and help to boost your ego?

Agreed.... Everyone makes mistakes.  You should point out mistakes in the
least personal matter. People don't learn if you attack them personally, and
they tend to shut off towards others.

*WE* are a team, *WE* broke it.

[Timo Kreuzer]

Ok, I need to defend Magnus here, I guess (thanks KJK::Hyperion for
noticing)

Actually, Magnus did the correct check and *WE* (*cough*) broke it.
Please check rostests/apitests/gdi32api/tests/GetTextFace.c

I refuse to put logic tables here. It was all correct!

"If it ain't broke, fix it till it is...."

here's how I tested the behavior of GetTextFaceW:

#define WIN32_LEAN_AND_MEAN
#define STRICT
#define NOMINMAX

#include <windows.h>

#include <stdio.h>
#include <tchar.h>

int main()
{
	HDC hdc = CreateCompatibleDC(NULL);

	TCHAR buf[1];

	int c = ARRAYSIZE(buf);
	LPTSTR lpName = buf;

	SetLastError(1); _tprintf(_T("GetTextFace(hdc, %d, %p) -> %d,
GetLastError() -> %lu\n"), 0, NULL,   GetTextFace(hdc, 0, NULL),
GetLastError());

	SetLastError(1); _tprintf(_T("GetTextFace(hdc, %d, %p) -> %d,
GetLastError() -> %lu\n"), 0, lpName, GetTextFace(hdc, 0, lpName),
GetLastError());

	SetLastError(1); _tprintf(_T("GetTextFace(hdc, %d, %p) -> %d,
GetLastError() -> %lu\n"), c, lpName, GetTextFace(hdc, c, lpName),
GetLastError());

	SetLastError(1); _tprintf(_T("GetTextFace(hdc, %d, %p) -> %d,
GetLastError() -> %lu\n"), c, NULL,   GetTextFace(hdc, c, NULL),
GetLastError());
}

// EOF

And this is the output:

GetTextFace(hdc, 0, 00000000) -> 7, GetLastError() -> 1
GetTextFace(hdc, 0, 0021FD70) -> 0, GetLastError() -> 1
GetTextFace(hdc, 1, 0021FD70) -> 1, GetLastError() -> 1
GetTextFace(hdc, 1, 00000000) -> 7, GetLastError() -> 1

(7 is sizeof("System"))

When lpName is NULL, the API always return the required size, ignoring
c. If a buffer is specified, it must be at least 1 character long (0
characters won't even fit an empty string), otherwise failure. Hence,
the success conditional is !(lpName && !c), i.e. (!lpName || c), which
is what it had been all along

[James Tabor]

OMG, now I'm getting dragged into this!

Okay Vista may not set GdiSetLastError but XP does! Did anyone bother
to check GetTextFaceAliasW? If anyone does please move it to
objects/text.c too.

Thanks,

[James Tabor]

Hi,
I simplified the program a bit~ 8^D

The compiler does things backwards sometimes. If this was a m68k
system it would have worked the first time.

Sorry,
James

Stating the revision number is enough (and useful). Stating the  
actual author is redundant, but might feed someone's ego (though I  
think it was never taken too close to heart).


WBR,
