ChangeLog-0.3.6

This is the changelog for ReactOS™ version 0.3.6 (not released yet), 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 0.3.5 (released 30 June, 2008).

Core

Bootloader (FreeLoader)

• Reduce Freeldr memory requirements: FreeLoader first reads entire ntoskrnl.exe (about 3M) into memory, then copies it to other address. Now, freeldr reads it straight to the place, not allocating extra memory for buffer (Dmitry Gorbachev, bug #3447)

IO

• Save pointer to driver's section in DriverSection during driver loading (Aleksey Bragin, bug #3221)

KD

• Fix an allocation of paged pool during phase 0 (Stefan Ginsberg)

• PDT of CSRSS has no entry for TCB of the thread, fix this problem (Dmitry Gorbachev, bug #3591)
• Get rid of a confusing goto in apc.c, a remnant of some code refactoring (Stefan Ginsberg)

MM

• Prevent boolean flags from being optimized away by compiler (due to PSEH usage) by making them volatile (Yury Sidorov, bug #3408)
• VirtualAlloc() fixes (Yury Sidorov, bug #3467):
  • Invalid parameter error is returned if requested memory area is located above USER_SHARED_DATA address (0x7FFE0000) (WinXP compatible).
  • Access violation error is returned if existing memory area found on requested address and this area have uninitialized region list.
• MiGetLastKernelAddress was totally broken on x86 and always returned the highest available physical page, thus the PFN database always end up at the address 0x80000000 and higher (just before the kernel). And when PFN database's size was bigger than usual (e.g. 1Gb of RAM and more), the PFN database zeroed out the kernel. This logic was introduced by 32640 commit. Fix it. (Aleksey Bragin)
• Implement MmDeleteVirtualMapping (ReactOS Portable Systems Group)

PS

• Don't leak critical region when going through failure return branch (Dmitry Gorbachev)
• Prevent BSOD if ObReferenceObjectByHandle failed in NtGetContextThread and NtSetContextThread (Yury Sidorov)

Hardware Abstraction Layer (HAL)

Run Time Library (RTL)

• Prevent crashes when heapPtr is NULL, also fix broken heap magic output (Aleksey Bragin, Roel Messiant)
• Implement RtlCaptureContext (ReactOS Portable Systems Group)
• Write a DebugService routine for ARM (ReactOS Portable Systems Group)
• Implement DebugService2 (ReactOS Portable Systems Group)
• Always call ZwRaiseException in user mode and RtlDispatchException in kernel mode. If RtlDispatchException failed call ZwRaiseException in kernel mode. Otherwise unhandled RtlRaiseException() call in kernel mode simply ignored (do nothing)! (Yury Sidorov)
• Call RtlRaiseStatus in RtlRaiseException, if something went wrong (Yury Sidorov)
• Speed-up user mode exception handling by calling RtlDispatchException() first if there is no active user mode debugger. This avoids switches to kernel mode if exception can be handled by SEH (Yury Sidorov)
• Implement RtlSetUserValueHeap, RtlSetUserFlagsHeap, RtlGetUserInfoHeap functions. It is quick implementation and it works. It fixes "Out of memory" error in all InnoSetup based installations. A lot of software can be at least installed in ReactOS now. Also it fixes Delphi applications which use TMemoryStream class. (Yury Sidorov)

Win32™ Personality

Kernel-mode subsystem server (Win32K)

• Fix a typo in the DC_ATTR structure (mxDevicetoWorld -> mxDeviceToWorld) (Stefan Ginsberg)
• Check if pool allocation succeeded right after allocation, not at the end of the function, when the pointer has been used quite a few times already (Aleksey Bragin)
