This is the changelog for ReactOS™ version 0.3.3 (released 12 September, 2007), an open-source operating system designed to be binary executable- and device driver-compatible with Microsoft™ Windows NT™ and subsequent Microsoft operating systems such as Windows 2000™ and Windows XP™. ReactOS is written by the ReactOS development team, and the last previous version of ReactOS was version 0.3.1 (released 10 March, 2007).


Generic 0.3.3 Changes

  • Source tree restructure and cleanup (Alex Ionescu, Aleksey Bragin)
  • Update DejaVu font to 2.18 (Magnus Olsen)
  • Switch to DejaVu font in all cases, Cmd is now using DejaVu font as well, the GUI already uses it (Magnus Olsen)
  • Import usp10 from Wine, CVS revision 1.8 (Magnus Olsen)
  • Add a test case for a few APIs of the Win32k DirectX support, like NtGdiDdCreateDirectDrawObject, NtGdiDdDeleteDirectDrawObject, NtGdiDdQueryDirectDrawObject. The test case is not 100% correct because of different faults, so you need to check by hand why it failed in some cases. The test case works on every Windows that supports DirectX8 or higher, or ReactOS 0.2.9 or higher (Magnus Olsen)
  • Change ObpDosDevicesShortName to match the ob.h header prototype (Magnus Olsen)
  • Many header compatibility fixes between our DDK and MS DDK version 3790.1830 (Magnus Olsen)

  • Fix (and optimize) KeRemoveByKeyDeviceQueue() routine (Aleksey Bragin).

  • Fix a bug with querying registry values (Herve Poussineau).
  • Fix a problem when a device, which was already in the list is freed and memory corruption is introduced (Aleksey Bragin).
  • Massive changes to the driver loading / device creation logic: Really reuse the driver's object (Aleksey Bragin).
  • Fix driver's object creation accordingly in NtLoadDriver() and IopActionInitChildServices() (Aleksey Bragin).

  • Give "RAW" filesystem driver a name (Aleksey Bragin).
  • Added a small piece of a new logic into IopCreateDriver(). In ReactOS it's being called two times almost immediately, which results in a non-unique driver object name, since KeTickCount is the same. In order to prevent this situation a loop is added, having 100 iterations as max (Aleksey Bragin).

Audio Stack

  • Fix incompatibility: In Windows IoGetDeviceProperty(DevicePropertyAddress) returns information as 0xDDDDFFFF (D=Device, F=Function) and not as a PCI_SLOT_NUMBER structure. This is confirmed by tests in Windows XP and 2003, and also found via Google (Aleksey Bragin).

Storage Stack


  • Check if the same Monitor ID (= 10 bytes from the EDID, which can be used to uniquely identify a monitor) appears two times and stop the child enumeration in this case. (Colin Finck, bug #2239)

NT System Library (NTDLL)

  • Implemented strtoull (msvcrt.dll & ntdll.dll, most generally in libcntpr) (Pierre Schweitzer, bug #2314)

  • Bug fixes for NtGdiDdCreateSurface, it can create one surface now, but it contains many bugs (Magnus Olsen)
  • Rewrite NtGdiDdBlt, it can now operate on a surface, but it might contain bugs (Magnus Olsen)
  • Revert revision 21677, this change is not needed, I confirm VMware's own graphics driver does not release the DX interface in windows XP/2003 or higher.
    I removed this, so the VMware driver gets a DX interface, this enables Windows XP graphics driver again. Unfortunately, there are no DX hardware accelerations from VMware any longer. (Magnus Olsen)
  • Remove a Windows 95/98/Me behaviour in NtGdiDdQueryDirectDrawObject, also tested under Windows 2000 to see if this behaviour really existed or not.
    puvmList and puNumHeaps should be ignored by Windows NT when they are passed down. After I fix the last part, this API is 99.9% compatible with Windows 2000 and higher. (Magnus Olsen)

  • Make the Device Manager open both devmgmt.exe in ROS and devmgmt.msc in Windows (Ged Murphy)

  • Compact
    • Implemented: Main_DirectDraw_Compact with the same behaviour as MS DirectDraw_Compact.
      According to MSDN, it is unimplemented and always returns DD_OK, but in fact it can return DDERR_NOEXCLUSIVEMODE in some cases. (Magnus Olsen)
  • GetMonitorFrequency
  • DirectDraw_QueryInterface
    • Found out a bit more how DirectDraw_QueryInterface works and commented the new investigations (Magnus Olsen)

      • Bug Fix: The linking interface was used, when we did not require a linking interface and the other way round. (Magnus Olsen)
      • Bug Fix: Cleaned up the linking interface code, so it gets simplier (like reusing the same DX handler and other stuff) (Magnus Olsen)
      • Bug Fix: Maarten Bosma noticed that I did take the wrong structure at the allocation, I also commented up the code a bit. Fixed by (Magnus Olsen)

      • Bug Fix: Fixed smaller bugs in startup.c, it does not set a window handler or use the window handler's hdc, it creates an own hdc (Magnus Olsen)
      • Bug Fix: Reactivate linking, create a link when you require a new DirectDraw interface from an old one. This way we do not create a new lcl pointer, but use the current one we got (Magnus Olsen)
      • Bug Fix: Rewrite a little part of Create_DirectDraw and add a "reenable" option. (Magnus Olsen)
  • Miscellaneous stuff
    • Bug Fix: CreateDirectDraw did crash (Magnus Olsen)

    • Commented which API are under development and hard tested. Marked which ones have been completed and act like the ones from MS DDraw. (Magnus Olsen)
    • Made ddraw.dll a little more msvs frendly (Magnus Olsen)
    • Added table lockups for DirectDraw 1-6, but they are not yet completed (Magnus Olsen)
