Re: [ros-dev] [ros-diffs] [fireball] 28351: Dmitry Chapyshev <lentind@yandex.ru>: - Fix so that letters like "p" or "y" are correctly displayed in messageboxes.

by Ged

IMO, this change is wrong, it's a hack to a problem we have with text placement. Text is cut short on other controls too, not just messageboxes. Check out labels for example.

Re: [ros-dev] [ros-diffs] [hpoussin] 28693: Implement IsUserAnAdmin(), by copying implementation of IsUserAdmin() in setupapi (was implemented by Eric Kohl) Redirect setupapi.IsUserAdmin to shell32.IsUserAnAdmin

by Jeremy Drake

Umm, this implementation of IsUserAnAdmin is not quite correct. I just had to deal with a function almost identical to this in real life, which gave the wrong answer on Vista due to the filtered token containing the Administrators group with the "for deny only" attribute. You need to either check the attribute portion of the SID_AND_ATTRIBUTE struct as well, or use something like CheckTokenMembership (assuming that is implemented properly), or construct a security descriptor and use AccessCheck (again, assuming that is implemented correctly (I would hope so...)). Of course, this is probably just overly anal on ReactOS, as you don't have the whole Vista filtered token/elevation mess (yet), but probably best to be technically correct...

GDI_TABLE_ENTRY structure

by Timo Kreuzer

Our current gdi handle and handle table entry code uses a bunch of macros, masks, bitshifts and even hardcoded values, iirc. This leads imo to errors, will make the code less portable and cannot make use of better compiler optimizations. So I have created a new GDI_TABLE_ENTRY struct and a new type GDIHANDLE. Both use unions and packed structs to directly access all fields. GDI_TABLE_ENTRY is completely compatible to our current one, so all the code would still be valid. + the compiler can optimize access of single elements better (movzx, byte ptr ...) + no more need for additional masks, shifts and macros + no more messed up code because of wrong hardcoded values + better readable code + probably easier porting to 64 bits - must be redefined for big-endian systems - direct access of stockbit is slightly slower, but could still be handled by a macro #pragma pack(push,1) typedef struct { PVOID KernelData; /* Points to the kernel mode structure */ union { DWORD ProcessId; /* process id that created the object, 0 for kernel objects */ struct { unsigned ProcessId16: 16; unsigned Unused: 16; }; }; union { ULONG Type; struct { union { unsigned TypeLower: 16; struct { union { unsigned HandleTypeStock: 8; struct { unsigned HandleType: 7; unsigned StockBit: 1; }; }; unsigned ReuseCount: 8; }; }; union { unsigned TypeUpper: 16; struct { unsigned StorageType: 8; /* PEN uses same value as BRUSH here, no stock bit */ unsigned Flags: 8; }; }; }; }; PVOID UserData; /* Points to the user mode structure, usually NULL though */ } GDI_TABLE_ENTRY, *PGDI_TABLE_ENTRY;; typedef union { HGDIOBJ Handle; struct { unsigned Index: 16; union { unsigned Upper: 16; struct { union { unsigned HandleTypeStock: 8; struct { unsigned HandleType: 7; unsigned StockBit: 1; }; }; unsigned ReuseCount: 8; }; }; }; } GDIHANDLE, *PGDIHANDLE; #pragma pack(pop)

Re: [ros-dev] current status of xen support

by Aleksey Bragin

There is still a branch "xen", where some work has been done, however it's greatly outdated. If someone has a wish, he could make a new branch. But we don't have any volunteers at the moment.

0.33rc2?

by Bernd Blaauw

Is there going to be a new release candidate of ReactOS version 0.3.3? I tested it very shortly and was very impressed with how it looked in comparison to version 0.3.0. Is there a list of known bugs as feedback from 0.3.3rc1 testers? Searching through Bugzilla might be a bit too much :). Anyway, the issues I experience in VMware 6.00 on WinXP Pro x64 host so far are: * diskette drive not visible (and/or working). Ever since 0.2.8 or so? * shutdown does not close the virtual machine (might be improper shutdown). Screen goes all black and need to enter VMware menu to shutdown the ReactOS virtual machine. Is the AUTORUN.INF by now the only file on the root of the CD? icons and readme files can go in subdirectories I guess, which makes adding ReactOS to multi-installation CDs a lot easier (a CD/DVD containing setup or LiveCD of various operating systems, mostly using the Isolinux bootloader for a frontend menu and chainloading bootsectors). I've not extensively tested the RC1 on for example if it still can complete installation and bootup with 32MB or less RAM installed (VMware allows anywhere from 4MB to 8GB in increments of 4MB, Bochs/Qemu allow 1MB increases). A resolved item I noticed in this new release was the ability to enter digits for the computername, wasnt possible previously in 0.3.0 or 0.3.1. ReactOS is getting interesting by now..a Win32 operating system with a size of about 50MB and capable of playing huge games sooner or later. Looks like a blessing to my limited size (16GB) DRAM based solid state disk.

[ros-diffs] [jimtabor] 22523: GetGlyphOutline, large wine port. Still testing.

by James Tabor

Hi, I have it half way done. Run the test program and you can see. Program works in W2k, XP and Wine. mingw32-gcc -mwindows -Os GetGlyphOutline.c -o ggo.exe I stopped messing with it two weeks ago, I needed to work on something else. When testing you can select the alphanumeric character with the keyboard. The original program had "a" but I changed it to "L" something simple to draw at first. You will see the problem. The test program from Dr. Dobb's Journal http://www.ddj.com/184409154?pgno=12 Thanks, James Runs and hides~

Re: [ros-dev] Will ROS and WINE still be steady be synchronized ?

by Aleksey Bragin

As I already said, the difference between ReactOS and WINE, as it's written in that Wine mailing list, is that ReactOS "is known" [by some] for reversing MS binaries, and Wine is not known for reversing MS binaries (though it does not imply ReactOS is always doing it, and Wine did [does] not reverse engineer). Also, Wine is not "Open Source community", it is *part* of Open source community, as are thousands of other projects, which somehow form the general perception of projects. WBR, Aleksey Bragin.
