This is a work in progress.

IMPORTANT: When adding a change, write a REAL NAME of the person, not his IRC or whatever nicks. This is an official paper. Also, reference bug numbers at the end of the change, in braces, like (your name, bug #2373).

This is the changelog for ReactOS™ version 0.3.4 (released when *censored* freezes over), 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 0.3.3 (released 12 September, 2007).

Build Tools

  • Add an "include/host" directory for Host include files (Colin Finck)
  • Correctly define LONG_PTR, ULONG_PTR and SIZE_T in "host/typedefs.h" (Colin Finck)
  • Define WCHAR to "unsigned short" in "host/typedefs.h", so it's always 2 bytes for host tools (Colin Finck)
  • Add a "nls.h" header file for many NLS definitions needed for WIDL and WRC (Colin Finck)
  • Remove a hack, which always defined __i386__ and lead to problems on other host platforms (Colin Finck)



  • Add folder support for msvc7+ solutions and mapping of pch .h files (Gregor Brunmar)
  • Fixed a small bug when displaying the version of binutils (newline where there shouldn't be one). (Peter Ward)
  • Do not use module (name + extension) as default target if installname attribute is present , use the value of it inset. (Marc Piulachs)
  • Metadata enhancement for rbuild and version report (Marc Piulachs)
  • Cleanup the LinkerScript class and use it (Marc Piulachs)
  • Rename 'base' to 'installbase' for CdFile, InstallFile and Bootstrap (Marc Piulachs)


  • Use "typedefs/host.h" instead of the Windows headers in "wine/unicode.h" and copy some needed definitions from the "winnls.h" (Colin Finck)



  • Use "typedefs/host.h" instead of the Windows headers in "wmctypes.h" (Colin Finck)


  • Use "typedefs/host.h" instead of the Windows headers in "wrctypes.h" and add a "wrcrostypes.h" for all needed definitions from the Windows headers (Colin Finck)


Kernel and Executive (NTOSKRNL)



  • Improve KDBG symbol loading mechanism, while still maintaining compatibility when compiled with KDBG=0 (Aleksey Bragin)
  • The debug object created by NtCreateDebugObject() is restricted to DEBUG_OBJECT_WAIT_STATE_CHANGE, change to DEBUG_OBJECT_ALL_ACCESS. (Timo Kreuzer, bug #2310)
  • Turn KDBG into KD-wrapper (Aleksey Bragin)


  • NtLoadDriver APIs refactor/improvement (Aleksey Bragin)
  • Almost completely fix the hack in IopParseDevice which was resulting in "FIXME: Broken Parse due to invalid DesiredAccess" messages, by changing some calls to IoGetDeviceObjectPointer to use FILE_READ_ATTRIBUTES instead of FILE_READ_DATA (so that the volume doesn't get mounted) (Aleksey Bragin)
  • Implement IoCheckEaBufferValidity() (Daniel Zimmerman)


  • Implement KiTrap19 handler (XMMI exceptions, mostly copied KiTrap7 handler and used mxcsr status word and exceptions there). (Aleksey Bragin)
  • Dynamically enable it, if CPU supports XMMI (was already done in the kernel, but #if0-ed). (Aleksey Bragin)
  • Fixed a typo in the line which lead to actual zeroing of mxcsr, instead of zeroing only reserved bits (spotted by Kamil Hornicek aka "Pigglesworth")
  • SSE/SSE2/etc is not broken anymore (Aleksey Bragin, bug #2748)
  • Copy kernel's IDT entries to the IDT we've got from the bootloader. Fixes boot-process initiated by ntldr-compatible loaders (Aleksey Bragin)
  • KeRosCaptureUserStackBackTrace is now created, which calls RtlWalkFrameChain with the user-mode flag, meaning that bugchecks finally show the user-mode stack again. (Aleksey Bragin)
  • KeRosDumpStackFrames is fixed so that if the EIP can't be found in a module list, it's still displayed (just without the module name). Previously the EIP would not be shown, resulting in code running on the heap/stack/somewhere else not being shown as part of the trace (Aleksey Bragin)
  • Coalesce all calls to MmUpdatePageDir through a single inlined function - MiSyncProcessThreadViews, and fix callers which assumed that the kernel stack is KERNEL_STACK_SIZE, when in fact, it may be KERNEL_LARGE_STACK_SIZE. We now detect and handle this, fixing a bug in KiAttachProcess. (Aleksey Bragin)
  • Unlock address space before raising to HIGH_LEVEL in KeBugCheck (Aleksey Bragin, bugreports/info by Alex)
  • Fix LoaderPagesSpanned calculation (Aleksey Bragin)
  • Plugged in batching. (James Tabor)



  • Changed Memory Manager's early initialization to be slightly more ntldr-compatible (Aleksey Bragin)
  • Move Teb's StaticUnicodeString initialisation from ntdll to MmCreateTeb (it's better to initialize it early, and all at once) (Aleksey Bragin)
  • Actually create (in the bootloader) and then respect the memory map (in memory manager) (Aleksey Bragin, thanks to Alex)
  • Fix PSEH return usage Johannes Anderwald


  • ObReferenceObjectByHandle/ObpReferenceProcessByHandle: Properly return STATUS_INVALID_HANDLE if user-mode tries to reference a kernel-mode handle
    Properly validate process/thread access rights before giving a reference to the caller. (Aleksey Bragin, thanks to Alex!)
  • Fix definition of "SizeOfHandle" macro in the handle table implementation. Fixes handle leaks at process rundown, handle allocation, and problems with processes that use more than 512 handles. (Aleksey Bragin, thanks to Alex!)
  • Remove checks for "VALID_INHERIT_FLAGS". These flags have nothing to do with handle table entries and shouldn't appear in them. (Aleksey Bragin, thanks to Alex!)


  • Fixed a bug in PnP Manager for drivers which failed initialization at boot-time (Aleksey Bragin)
  • Improved compatibility in PnP Manager, driver's load and unload routines are alwyas called in context of the system process (Aleksey Bragin)
  • Correctly set DN_DRIVER_LOADED flag. This fixes multiple installation of i8042prt/kbdclass.sys on every boot. (Aleksey Bragin, bug #2330)



  • Fixed incompatible SeSet/QuerySecurityAccessMask() behaviour (Aleksey Bragin)

Hardware Abstraction Layer (HAL)

Run Time Library (RTL)

  • Fix multiple bugs in RtlWalkFrameChain and secure it against any possibility of a bugcheck while walking the stack. (Aleksey Bragin, bugreports and info by Alex)
  • Fix bugs in RtlUnwind and RtlExceptionDispatch which assumed the DPC stack size was 4KB instead of 12KB. (Aleksey Bragin, bugreports and info by Alex)
  • Fix multiple bugs in RtlpGetStackLimits and secure it against bugchecks. Properly detect DPC or invalid stacks. (Aleksey Bragin, bugreports and info by Alex)

Kernel Mode Drivers


  • Fixed the issue with floppy.sys hanging on boot (Cameron Gutman, bug #1508)


  • Reorganized NTFS driver header : renamed Magic to jump, and OemName to OEMID, created structures for BPB and EBPB and used them in BOOT_SECTOR one, added a field to BOOY_SECTOR structure. This is based on a Technet document and Alex Ionescu document (Pierre Schweiter)


  • Moved the functions MOV_DD_SWP (the i486 version), MOV_DW2DD_SWP and MOV_DW_SWP to an external assembler file (Colin Finck)
  • Silence many warnings (Colin Finck)
  • Fix a bug, where all ATI chips were treated as Silicon Image chips (Colin Finck)
