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).

Host Tools

Buildno

• Fix warnings when compiled with gcc 4.2 or later (Daniel Verkamp)

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)

Kernel and Executive (NTOSKRNL)

EX

• Include a "System Idle Process" as the first item in QSI SystemProcessInformation (Aleksey Bragin)

• Pass thread's CreateTime in QSI SystemProcessInformation (Aleksey Bragin)

• Better implementation of QSI SystemInterruptInformation (Aleksey Bragin)

• Remove a hack in the executive handle implementation which worked around a memory corruption bug (Stefan Ginsberg, bug #3512)

IO

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

• Fix unloading function to check if a driver to be unloaded really has DriverSection set, and if not, fail (Aleksey Bragin, bug #3221)

• Fix Irp flags assignment in case of an IoAllocateIrp call with ChargeQuota set to TRUE (Aleksey Brgin)

• Fixed double freeing of IRP in NtSetInformationFile (Michael Martin)

KD

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

KE

• Fix a problem with normal and special APCs being inserted in the wrong order, spotted by Jury Sidorov. Now Borland Turbo Debugger should be able to debug applications, also it can fix hangs in other applications (Aleksey Bragin, Yury Sidorov, bug #3426)

• PDT of CSRSS has no entry for TCB of the thread, fix this problem (Dmitry Gorbachev, bug #3591)

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)

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)

Run Time Library (RTL)

• Prevent crashes when heapPtr is NULL, also fix broken heap magic output (Aleksey Bragin, Roel Messiant)

• 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)

Kernel Mode Drivers

AFD

• Move IRP completion out of spinlock (Cameron Gutman)
• Fix problems with handling cancelled IRPs (Cameron Gutman)
• Fix a few memory leaks (Cameron Gutman)
• Fix lock releasing issues (Cameron Gutman)
• Don't pass a bad IRP on failure (Cameron Gutman)
• Also cancel the connect IRP (Cameron Gutman)
• Add DeviceObject checks (Cameron Gutman)
• Unlock MDL pages before completing (Cameron Gutman)

TCPIP

• Fix problems in the IRP cancellation routine (Cameron Gutman)
• Fix a problem in which we wait on an event that isn't set (Cameron Gutman)
• Don't mark the IRP as pending while setting its cancel routine (Cameron Gutman)
• Remove a hack from DispTdiSendDatagram (Cameron Gutman)

NDIS

• Reenable commented out spinlocks in MiniIndicateData (Cameron Gutman)
• Don't raise IRQL before calling MiniDoRequest (Cameron Gutman)

BOOTVID

• Fix a problem in VgaIsPresent: Content of the Address Register goes to the Data Register, and vice versa. It also writes content of the Map Select Register (which is number 4) into the Bit Mask Register (number 8) (Dmitry Gorbachev, bug #2125)

SCSIPORT

• Don't release the same spinlock twice on failure (Cameron Gutman) (bug #3520)

NT System Library (NTDLL)

• Initialize TLS expansion bitmap properly, it fixes accessing uninitialized memory when all regular TEB slots for TLS data are occupied (Aleksey Bragin)

• Add an initial breakpoint for usermode process startup, this makes usermode debuggers working (Yury Sidorov, Aleksey Bragin)

Static Libraries

CRT

• Use "size_t" instead of "unsigned int" where appropriate in crt string functions (Samuel Serapión)
• Fix double linking of snprintf, _snprintf should be used in CRT (Aleksey Bragin)
• Implement %p for scanf (Peter Oberndorfer)
• Implement ___setlc_active_func/___unguarded_readlc_active_add_func (Jon Griffiths)

TCP

• Release spinlock on failure path before returning (Cameron Gutman)

Keyboard Layouts

• Add Slovak QWERTY keyboard layout (kbdsk1.dll) by Mário Kačmár (bug #3528)

USETUP

• Remove all translations for the "Paged Memory", "Nonpaged Memory" and "Free Memory" progress bars.
  This is debug stuff, which should have never been translated. As the translated strings are also sometimes longer than the english ones, they led to unnecessary problems like text overlapping. (Colin Finck)

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)

• Remove XFORM members from DCLEVEL and use MATRIX instead (Stefan Ginsberg)

• Fixed RestoreDC and lots of visual glitches as result. Especially in Delphi applications (Yury Sidorov, bug #3491)

Services

services

• Implemented ScmDeleteMarkedServices. Services can be deleted now (Yury Sidorov)

Control panel applets

Intl

• Fixed country codes (each country appears once only) (Matthias Kupfer) (bug #3488)

Timedate

• Fixed flickering clock (Matthias Kupfer)
• Extended range of years in month view (Matthias Kupfer)

Win32™ Libraries

ADVAPI32

• Check for correct access, DELETE, when deleting services (Michael Martin)
• Dependencies param in CreateService is a double terminated string array (Michael Martin)
• Fixed dependency string length to pass correct size to rpcserver (Michael Martin)

DNSAPI

• Fix heap corruptions and memory leaks (Art Yerkes, Colin Finck, Samuel Serapión)

GDI32

• Fix a typo in the DC_ATTR structure (mxDevicetoWorld -> mxDeviceToWorld) (Stefan Ginsberg)

MSAFD

• Properly handle STATUS_TIMEOUT (Cameron Gutman)

• Added comments to the CPTABLEINFO structure based on documentation from http://www.ping.uio.no/~ovehk/nls/ (Colin Finck)
• Add a new check for 'MultiByteCount < 0' to WideCharToMultiByte (verified under WinXP SP2) (Colin Finck)
• Fixed WriteProcessMemory. With this fix applied, user mode debuggers are able to work much better - be able to write in memory, set breakpoints, etc. (Yury Sidorov, Aleksey Bragin, bug #3415)

MSVCRT

• Fix ordinals of msvcrt according to Windows Server 2003 SP1's msvcrt.dll (Colin Finck)
• Implement new versions of wctomb and wcstombs, which consider the language set by setlocale() and work according to all behaviours I could find when testing under WinXP SP2 (Colin Finck)
