I mean, what if the probing fails? Should the paging executive somehow preempt this call and page in the missing pages (or should it simply throw a "page not present" exception - not too great to do at DPC level I'd say)? >which means the driver probably called it for a >non-paged pool address. If my previous suspicion is correct, I build on that and suspect this is an error in itself. The ProbeAndLock call should be done at APC level (though I may be completely wrong, but do read my finishing line). >In that case, the whole loop about checking if the page is present and >then faulting it in is irrelevant, and won't happen. Right. Page fault at DPC level == Bad Move(tm). -- Mike

This breaks compiling on Mac OS X... I haven't been able to build since this patch, because now it tries to include windows.h.

widl problem importing stdole2.tlb
by Steven Edwards 23 Jul '08

23 Jul '08

Hi, I've been attempting to sync some of the Wine dlls, namely the IE support dlls and have run in to a bit of a problem which I think is a bug in ReactOS widl. It seems that the import keyword is not working. When trying to build shdocvw.dll it creates a shdocvw_v1.tlb based on shdocvw_v1.idl which imports exdisp.idl from the SDK which in turn does an import ("stdole2.tlb") As you can see from the output below sedwards@mini-gimli:~/source/reactos$ make shdocvw [WIDL] obj-i386/dll/win32/shdocvw/shdocvw_v1.tlb error: Could not open importlib stdole2.tlb. mingw32-make: *** [obj-i386/dll/win32/shdocvw/shdocvw_v1.tlb] Error 2 Total Build Time: 00:00:02 Notice the . at the end of stdole2.tlb? I've tried just renaming the typelib and putting it in several intermediate folders to no effect. If any WIDL Guru can help please find the attached patch which contains an updated shdocvw.rbuild Thanks Steven -- Steven Edwards "There is one thing stronger than all the armies in the world, and that is an idea whose time has come." - Victor Hugo

kernel32
by gedmurphy 23 Jul '08

23 Jul '08

Yesterday I was playing around with the test suite in HEAD when I moved onto kernel32. It was, without wanting to sound too harsh, a bit of a disgrace, with large failures throughout the whole test range. I suggest a hacking day on it using the test suite, a joint effort to bring this core lib back into line. Perhaps with some emphasis on trying to make it fun. Whoever gets the most fixes is crowned 'king ding-a-ling' and holds the title until the next one, opening the road up to days on ntdll, user32, gdi32 and crt? Ged.

Request for Comment / Setup

23 Jul '08

Hi all, I'm working on first stage gui setup. During the development i reviewed the base/setup directory and the different modules. I suggest following changes: Now: reactos.exe: atm greeting only with disabled first stage setup dialogs setup.exe: switcher for 2nd stage setup (syssetup) or livecd usetup.exe: textmode 1st stage setup vmwinst.exe: don't know exactly, vm-ware driver installation welcome.exe: nice welcome dialog without real functions Future: setup.exe: switcher for 1st stage gui setup, 2nd stage setup, livecd and welcome dialog switched by command line arguments "setup.exe" -> welcome dialog "setup.exe -mini" -> livecd "setup.exe -newsetup1" -> 1st stage gui setup "setup.exe -newsetup2" -> 2nd stage (gui) setup usetup.exe: textmode 1st-stage-setup vmwinst.exe: keeps unchangend reactos.exe, welcome.exe: removed Are there any objections to go this way? If not, so i will change this soon. Matthias -- Matthias Kupfer Telefon +49 (0) 371 236 46 52 Wilhelm-Firl-Straße 21 Mobil +49 (0) 160 859 43 54 09122 Chemnitz
