Not necessarily, it may be considered a feature to load version info from the native dll, even though the actual code will run from the builtin. This may help programs believe they got the exact version they wanted (since presumably the app installed the dll in the first place). > Will DONT_RESOLVE_DLL_REFERENCES work with built-in dlls somewhere in the future? Unlikely; the problem is that we cannot prevent constructors from running, and we need to resolve imports before running constructors. -- Alexandre Julliard julliard(a)winehq.com

I think it's reasonable to give the native dll priority when doing LOAD_LIBRARY_AS_DATAFILE. An app using this wants to poke inside the dll binary file and we are much better off giving it the 'real' thing in this case IMO. -- Alexandre Julliard julliard(a)winehq.com

Re: RFC: client side implementation of async I/O
by Mike McCormack 19 Mar '01

19 Mar '01

Hi All, WWW reported that my client side async patch relies on the service thread... sorry for not clearly explaining, but it doesn't. It works by multiplexing the server's wait reponse fd with pending i/o operation fds using poll. When i have time, i'll try to clean it up a bit. Currently i'm working on a kernel patch to help implement other WaitCommEvent flags. i hope Alexandre considers applying the client side async patch in some form.

First thanks for the bug report. The trace is not difficult to read, the menu item is a text item and the text pointer is NULL. MENU_CalcItemSize is not handling this case. What is strange is this problem appears only with my patch. Maybe your app is really initializing the menu when receiving the WM_INITMENU message, but *only* when there is need to display the menu. I can't see how it could find out about it, though. Anyway, could you try the following patch ? It tries to remove the main case I saw where the app can set a menu item to text type with a null text pointer. It is a legitimate patch by itself, even if it does not fix your problem. Maybe it could have nasty side effects. If it avoids the systematic crash, try to find if the other is really gone for good too. I have found a strangeness in the HEAP_strdup macros - WARNING - this is of interest to anyone dabbling with Wine code. While HEAP_strdupW and HEAP_strdupAtoW appear very similar, the specs are not the same; one returns a null pointer when called with a null pointer, the other allocates 2 bytes of memory and returns a pointer to it. Nice trap :-) Gerard --- menu.c.orig Wed Mar 14 20:19:46 2001 +++ menu.c Sat Mar 17 14:47:30 2001 @@ -4524,11 +4524,15 @@ menu->text = lpmii->dwTypeData; - if (IS_STRING_ITEM(menu->fType) && menu->text) { - if (unicode) - menu->text = HEAP_strdupW(GetProcessHeap(), 0, lpmii->dwTypeData); - else - menu->text = HEAP_strdupAtoW(GetProcessHeap(), 0, (LPSTR)lpmii->dwTypeData); + if (IS_STRING_ITEM(menu->fType)) { + if (menu->text) { + if (unicode) + menu->text = HEAP_strdupW(GetProcessHeap(), 0, lpmii->dwTypeData); + else + menu->text = HEAP_strdupAtoW(GetProcessHeap(), 0, (LPSTR)lpmii->dwTypeData); + } + else + menu->fType |= MF_SEPARATOR; } }

There are applications testing the version number of the common controls - tons of them : all the apps written with modern Borland tools. Their behaviour change accordingly because Ms changed things quite a lot with 4.72. Wine does not emulate the old behaviour, so it's needed to return a recent version number to get some apps to work correctly. Unless the version number of winsock.dll, richedit.dll, version.dll, or unrelated dlls like that is always identical to the version number of common controls ? I did not check but that seems unlikely. >1. I believe that version numbers should be equal in both numerical field and >in the string value (0.01 != 4.72 and 1.00 != 4.72). >2.

Version resources in kernel, user, gdi for both 16 and 32-bit dlls could serve >as an example of adding version resources into built-in dlls. Well, all right I'll do like it's done in include/wine. I did not search far enough, I used the file in commdlg as an example :-) I found another problem you missed btw, there is a special function to retrieve the dll version directly, it returns hard coded values; I'll add code to retrieve these from the resource.

I have noticed a couple of crashes at controls/menu.c 872 since I applied this - when I fatfinger something in the wm (icewm) and keyboard input gets directed to a different window, but the event comes to wine, I think, but I haven't looked into it too closely and I'm not sure I can reproduce it. /* If we get here, then it must be a text item */ if (IS_STRING_ITEM( lpitem->fType )) { SIZE size; GetTextExtentPoint32W(hdc, lpitem->text, strlenW(lpitem->text), &size); and in this case lpitem is NULL and the strlen crashes. Would you be interested to see traces if I can reproduce it (if so which traces)? I think maybe it is a wm bug, but maybe wine should protect itself if it is not too expensive to do so?

Re: Eliminate excessive retries in GetFileVersionInfo(Size)

Good day! Maybe it takes a Man from Mars to think that a windose function might ought to sort of do what its name implies, but the more I think about it, wouldn't it be simpler? It is right and proper for the functions of oleaut32.dll to be performed by liboleaut32.so and friends (if the Wine administrator so directs), but if the app asks for the version info for oleaut32.dll, and the named file exists (because the app's installer _put_ that file there, in this case) how about we give it the version info from that bloody file? If the file doesn't exist, we give it a builtin construct, say. IOW, disconnect file version from dll. I don't think it is any business of the app what does its work, so I don't see why it should be able to tell by GetFileVersionInfo whether the working blah.dll is builtin or native. I guess you could make a case for a [VersionOverrides] section in the config, but I am not going to. That way lies madness. I would be willing to take a shot at writing the code if that's what we decide we want, and if no one is in a great hurry for it, but...
