Bugzilla maintainer
by Aleksey Bragin 19 Sep '07

19 Sep '07

Hello, Amine Khaldi is going to be a bugzilla maintainer, starting tomorrow. This is the first step from the a number of efforts I'm going to announce soon, which aim significant improving of the development process, resulting in less breakages and more smooth development progress. You can see what the work of a bugzilla maintainer is at the following wikipage: http://www.reactos.org/wiki/index.php/ Bugzilla_Maintainer With the best regards, Aleksey Bragin.

ReactOS status
by Carlos Alexandre Pires 18 Sep '07

18 Sep '07

Hi, my name is Carlos Pires, and i've been tracking this project since 2006, and now I've managed to get some time for me to get involved in it. I've fetched the svn sources, and past this last 3 days looking at the code, trying to find how was going the implementention. I've also download tinykrnl for analsys, and realized that reactOS does not implement some hal fuctions like HaliQuerySystemInformation, trying to find more information one this i've also realize that reactOS does not have a Machine Check Handler. I noticed that a lot of effort is being made in User Mode code, to make software work in reactOS. I've also check svn activity and checked that the Kernel Mode code had minor changes (i've only looked at dates). Now, i've said that, i have a few questions: - How is the Kernel Mode implemention current status? - Looking at Windows architecture, the HAL part is one of the most important thing in making Windows device drivers work in reactOS, shouldn't this be ReactOS first goal? - Isn't more important to create a fully working Kernel (executive,hal,etc) before going into User Mode? Sorry if i've said something that is not correct, this are only thoughts i've had, while i was looking at the code. I'm a developer and want to help as much as i can this project, so if anyone can help in getting some lights about the current status, i appreciate. The best regards

Re: [ros-dev] [ros-diffs] [silverblade] 29089: Bare-bones foundations of the ReactOS Audio Service. At present it's nothing more than a "mutex service". Some info on the planned implementation is in the included audiosrv.txt file.

Problems with resources or something else
by carlo.bramix 16 Sep '07

Hello, it's long time that I compile ReactOS and I have some errors into the start menu bar. My results are almost identical to this screenshot: http://www.reactos.org/media/screenshots/2007/ros_033_xara3d.jpg As you can see, the two icons after the start button and the '1','2','3','4' buttons are corrupted. Actually I'm using the windres.exe that I received from here: http://www.reactos.org/archives/public/ros-dev/2007-July/009548.html Do you have some idea?

Linking problems
by Marc Piulachs 15 Sep '07

15 Sep '07

Does the order of .o files matter when linking against a static library? I ask this because I'm having problems linking ntoskrnl with rtl dependending on the order of object files when compiling rtl. For example on the rbuild generated makefile.auto the order of .o files is : rtl_OBJS := \ $(INTERMEDIATE)\lib\rtl\austin\avl.o \ $(INTERMEDIATE)\lib\rtl\austin\tree.o \ $(INTERMEDIATE)\lib\rtl\access.o \ $(INTERMEDIATE)\lib\rtl\acl.o \ $(INTERMEDIATE)\lib\rtl\atom.o \ $(INTERMEDIATE)\lib\rtl\bitmap.o \ $(INTERMEDIATE)\lib\rtl\bootdata.o \

In the rbuild generated file the .asm files generating this problem will be added to the end of the list because they are inside an If condition (ARCH=i386) so this ¿bug? does not appear even when exists Am I missing something here?

gdi object code optimization
by Timo Kreuzer 07 Sep '07

07 Sep '07

Hi Here are some ideas for optimizing our gdi object code: 1.) When allocating, locking and deleting a gdi object, we pass the global variable GdiHandleTable to GDIOBJ_AllocObj(). Do we really need this? Is there a case where we pass something else? We would only save few cycles here, but if we don't need it... 2.) When allocating a gdi object, we first need to search the list of LookasideLists. My suggestion is to give each gdi object type a constant index in the list and pass that index instead of the object type value. That would require that the table for the object types/sizes/CleanupProc is in sync with the index definitions. This could be achieved by initializing that table on win32k load: InitGdiObjectType(UINT Index, LONG GdiType, ULONG_PTR ObjectSize, GDICLEANUPPROC CleanupProc); Then we only need to make sure, that every index is only there once and add one line for each object in GDIOBJ_iAllocHandleTable to initialize the object type. 3.) ROS makes massive use of gdi object handles. It uses a lot more handles than windows does. That is because every object we use is always inserted into the handle table. This is slow and wastes handle entries, wich are a limited resource. Whenever we need a (temporary) object, we allocate it (find lookaside list, allocate mem, find free entry, lock entry, do some stuff, unlock entry), then in a second call lock it (do some checks, lock entry, return pointer) and at the end unlock it and then delete it. I think we should rewrite the code a little, so that we only create handles, when the object reaches usermode and use pointers to mem objects instead if the objects are kernel mode / temporary only. XXXOBJ_AllocObj(UINT Index) -> allocate an entry from the LookasideList and initialize it. Don't create a handle. XXXOBJ_FreeObj(PVOID pObjBody) -> free the entry from the LookasideList GDIOBJ_CreateHandle(PVOID pObjBody, UINT Index, LONG GdiType) -> create a handle for a given mem object rewrite some XXXOBJ_Xxx apis to deal with pointers to the mem objects instead of handles (see REGION_Xxx apis) Imo this should result in a big speed increase for several ntgdi/ntuser apis Regards, Timo
