There are almost 300 occurences of memory reallocation, and we need to somehow keep track of what was reviwed/fixed etc., otherwise we risk missing quite a few... We should start with a comprehensive list of things that need fixing... -- Dimi.

Protected mode interrupt problem
by Mike McCormack 08 Oct '03

08 Oct '03

Hi All, I've run into an interrupt related problem with Quicken 2002's installer. Two 16bit programs launch, one after the other. Each program hooks INT 0, however since our interrupt tables are global to all tasks, the second task retrieves the interrupt vector that the first task set. The first task exits, and restores the original INT 0 vector. When the second task exits, tries to restore the INT 0 vector set by the first task, which now has an invalid selector, so it crashes. After a bit of discussion and writing a test program, we discovered that it appears that some interrupt vectors are task local, and some are global. The local ones appear to be stored in the TDB (task descriptor block), in offsets 0x26 - 0x4a. The attached patch fixes this, though we're not sure that it is correct for DOS programs. I have enclosed a test program that shows the problem.

Thanks. -- Dimi. P.S. Inlining them is _far_ supperior to attachment. First, we can review them without any additional action.

Theme configuration options
by Kevin Koltzau 08 Oct '03

08 Oct '03

I've come to a point in the development of uxtheme where configuration options will be needed, and am looking for feedback on how this should be done. I currently forsee the following options needed: EnableTheme ="Y|N" ThemeMethod = "XP|GTK|KDE|..." GTK, KDE, etc are conceivable, but wont be in initial implementation, will default to XP ThemeName="name of theme" for example "Luna" if ThemeMethod=="XP" and the default XP theme is installed These should probably go into the [Tweak.Layout] section (possibly only enabled with a "WineLook"="WinXP") and of course needs the ability for application specific settings The theme API also has a function EnableTheming(BOOL) which under XP turns theming on/off for all applications immediately (all applications are redrawn), and it is persistant across reboots. I havent checked up on if I can update the EnableTheme config option from code, or if I would need to possibly store this value elsewhere in the registry Another possible option would simply be to only apply that call to the current running app, and not make it persistant..but that would deviate from how windows handles it Thanks Kevin

Byteswapping
by Warren_Baird＠cimmetry.com 08 Oct '03

08 Oct '03

Hi all, There are some changes I'd like to submit as patches, but I'm not sure the best way to go about it. We need to add some byteswapping code in a few places to make things happier on big-endian machines. The problem is that the byteswap macros only exist inside wine/tools/wrc right now - we've added a new header containing the byteswap macros in wine/include, and so they are just duplicated in wine/include and wine/tools/wrc - but this is hardly the ideal solution. The best solution I can think of at the moment is to put the byteswap macros into wine/include/wine/port.h, which is one of the few main wine header that is included in the wrc code - but then we'll have to include config.h and port.h in at least one place they aren't currently included : dlls/ole32/storage32.c Does anyone have any better suggestions? Thanks, Warren

Problem with NONAMELESSUNION on MS_VC and Mingw
by Steven Edwards 08 Oct '03

08 Oct '03

Hello, I have been having problems compiling on Mingw and MS_VC + PSDK code that uses #define NONAMELESSUNION. This is not the first place I have ran in to this problem. When I try to build libwine I am getting the following error: loader.c: In function `fixup_resources': loader.c:193: error: union has no member named `s3' loader.c:194: error: union has no member named `s3' loader.c: At top level: loader.c:170: warning: `fixup_imports' defined but not used make: *** [loader.o] Error 1 I had the same problem on MS_VC with the PSDK but I cant test/submut another report on this right now as my broadband at home on my dev box with the PSDK is still out. Can anyone else with the PSDK check? Thanks Steven __________________________________ Do you Yahoo!? The New Yahoo! Shopping - with improved product search http://shopping.yahoo.com

Re: Abort glyph rendering if everything is clipped
by Warren_Baird＠cimmetry.com 08 Oct '03

08 Oct '03

> It would be better IMO to do that as part of the clip rectangle > calculation a few lines below. Well, it was intended as an optimization - if we move the check down to the "if (flags & (ETO_CLIPPED) ..." clause, we may end up doing a HeapAlloc, and calls to GetGlyphIndices and GetObject that we don't need to do. I'd much rather bail out as soon as we can and avoid doing all of that extra work... Warren
