problem with treeview
by steve.lustbader＠philips.com 19 Nov '02

19 Nov '02

My app calls TreeView_InsertItem, which leads to a crash in ntdll.dll. A backtrace is available at http://www.lustbader.net/bt.txt, and I can provide any other debug output if anyone thinks it will help. TreeView_InsertItem is called like this: TVITEM tviFoo; tviFoo.mask = TVIF_TEXT | TVIF_PARAM; tviFoo.pszText = LPSTR_TEXTCALLBACK; tviFoo.lParam = (LPARAM)pFoo; //pFoo is guaranteed to be non-NULL TVINSERTSTRUCT tvinsFoo; tvinsFoo.hParent = TVI_ROOT; tvinsFoo.hInsertAfter = TVI_LAST; tvinsFoo.item = tviFoo; HTREEITEM hTreeFoo = TreeView_InsertItem(m_hWndUserTree, &tvinsFoo); Any ideas? -Steve

msvcrt vs std incl
by Dimitrie O. Paun 19 Nov '02

Hi guys, Here's a small test program: #include <windows.h> #include <stdio.h> #include <stdlib.h> #include <assert.h> int main() { printf("sizeof(wchar_t)=%d\n", sizeof(wchar_t)); return 0; } And I want to compile this with our msvcrt headers. Look what happens: [dimi@dimi wine]$ gcc -nostdinc -fshort-wchar -I /home/dimi/dev/wine/wine.src/include/msvcrt -I /home/dimi/dev/wine/wine.src/include test.c In file included from /home/dimi/dev/wine/wine.src/include/windows.h:38, from test.c:1: /home/dimi/dev/wine/wine.src/include/winbase.h:23:20: stdarg.h: No such file or directory In file included from /home/dimi/dev/wine/wine.src/include/windows.h:38, from test.c:1: /home/dimi/dev/wine/wine.src/include/winbase.h:1257: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/winbase.h:1258: parse error before "va_list" In file included from /home/dimi/dev/wine/wine.src/include/windows.h:40, from test.c:1: /home/dimi/dev/wine/wine.src/include/winuser.h:23:20: stdarg.h: No such file or directory In file included from /home/dimi/dev/wine/wine.src/include/windows.h:40, from test.c:1: /home/dimi/dev/wine/wine.src/include/winuser.h:4459: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/winuser.h:4460: parse error before "va_list" In file included from test.c:2: /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:13:20: stdarg.h: No such file or directory In file included from test.c:2: /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:135: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:175: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:176: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:177: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:184: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:211: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:212: parse error before "va_list" /home/dimi/dev/wine/wine.src/include/msvcrt/stdio.h:213: parse error before "va_list" test.c:4:20: assert.h: No such file or directory test.c: In function `main': test.c:8: `wchar_t' undeclared (first use in this function) test.c:8: (Each undeclared identifier is reported only once test.c:8: for each function it appears in.)

Please do not ask why so many includes, I know they are not needed, but it should work, right?

Question: domain name
by Martin Wilck 19 Nov '02

19 Nov '02

Using a default domain name in Wine would be beneficial for certain Netapi functions. While it's no big deal to add a config option for that, there is the Windows registry value DefaultDomainName in HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion\Winlogon which could be used for exactly that purpose. Is it better to - use a Wine config key, - use the above MS key, - or use both, the Wine key overriding the MS one if set?

I'm don't think we have any policy concerning this. Perhaps we should have. One thing that you shouldn't assume is for example that if a function exists its reentrant variant exists as well. For example that fact getpwnam exists doesn't imply that getpwnam_r exists. And yes, you really should use the reentrent variant if present as well as having an alternative implementation if not. As to the implict existance question: I'm not sure. First of all, to answer the related question: Should you have a alternative implementation for defined(HAVE_GETPWUID) && !defined(HAVE_GETPWNAM)? IMHO the answer is no. It is not worth the effort to support hypotetical platforms unless we can verify the existance of one. To return to the original question: I suggest that we should detect the presence or absence of ALL function we use that is verified not to exist on some platform and have for example code like #if defined(HAVE_GETPWUID) || defined(HAVE_GETPWNAM) || defined(HAVE_GETPWENT) # if (defined(HAVE_GETPWUID) + defined(HAVE_GETPWNAM) + defined(HAVE_GETPWENT)) == 3 # define __HAVE_GETPW # else # error All or none of the functions getpwuid, getpwnam and getpwent are assumed to exist # endif #endif in order to formalize the assumptions and generate a common define to use in the code. Comments? Suggestions?

If it is not too much effort, could you elaborate on the derived work issue. I have been thinking about trying to stub out, then work at implementing, a particular component. Rather than have someone else do the work, I am more interested in learning about doing it myself, and about any issues (legal and technical) involved. I am not asking for a complete howto here, but even a summary of the highlights would be quite valuable (to me at least). -- Thanks -- Jeff S. _________________________________________________________________ Add photos to your e-mail with MSN 8.

Configure question
by Martin Wilck 19 Nov '02

19 Nov '02

I am thinking about some netapi32 improvements where I'd need to call the functions of the getpw/getgr family: getpwnam(), getpwent(), getgrent(), etc. Configure checks for the "pwd.h" header and getpwuid(). Must I add more checks for all the functions I use, or is it ok to assume that getpwuid() presence implies getpwnam() presence?

windres vs. wrc
by Dimitrie O. Paun 19 Nov '02

19 Nov '02

Folks, I've just discovered (DUH!) another free resource compiler: http://www.redhat.com/docs/manuals/gnupro/GNUPro-Toolkit-98r2/5_ut/c_Usingb… This one is part of binutils. Now, like any good hacker, I hate such code duplication. Granted, I haven't looked through the code of windres, so I can't say if it's any good. However, here are some points to ponder: -- all Win32 free software projects out there use windres, not wrc -- for this reason, it is like it's more generic / better maintained -- do we want eventually to phase one of them out? -- their command line arguments are incompatible. This causes problems when trying to build portable Makefiles. Should we try to be command line compatible with windres, so we are a drop in replacement (for the .rc/.res -> .o conversion)? Any windres experiences? Comments? -- Dimi.
