Generic 0.3.14 Changes

  • CMake and MSVC efforts continue and a variety of linking bugs have been resolved due to differing strictness between GCC and MSVC.
  • Service control manager events are now logged in the system log.
  • Service startup and shutdown has been cleaned up significantly.
  • The pagefile has been limited to 2GB in size due to FAT limitations.
  • Services will now always return ERROR_SUCCESS when they have successfully started.
  • Both the VBE and VGA drivers are being marked as VGA compatible as a hack due another bug preventing VirtualBox's video driver from loading when the VBE driver is installed.
  • Wireless network support has been merged into ReactOS. Currently ReactOS is able to join unsecured and WEP secured wireless networks.

Known Issues

  • There exists a memory manager bug that consistently occurred when attempting to install ReactOS using the VirtualBox 4.x series. The issue manifests as a hang when the installer attempts to copy over the mshtml.dll file. A hack was applied that appears to eliminate the issue, but users who encounter it can also use VirtualBox 3.x or another virtual machine platform.
  • Skype and TuxPaint both crash right now.

Applications

  • 3DText: Rotation is now independent of computer speed.
  • Calc: Buttons have been realigned to better match calculator in Windows XP.
  • CharMap: Skeleton for advanced view implemented. Font zoom when scrolling and changing fonts has been fixed.
  • Cmd: File IO functions have been replaced with memory IO functions for batch files.
  • Device Manager: New device manager using ATL has been begun. Main window focus defaults to treeview to allow easier navigation by keyboard.
  • MSPaint: Cut function implemented.
  • Notepad: Notepad is now marked as unicode.
  • Ping: Option parsing has been made stricter and more robust.
  • Rapps: Links have been converted from FTP to HTTP until underlying Wine library starts supporting FTP.
  • Regedit: Ability to parse and display REG_RESOURCE_LIST values added. User is now prompted when importing from commandline. Fixes to handling of REG_MULTI_SZ values.
  • SndVol32: Application to control setting the volume in ReactOS.
  • Spider: Yes/No dialog is now used for exiting the game instead of Okay/Cancel.
  • Taskmgr: Terminating an application now uses 1 as the exit code.

  • Floppy disk is now correctly formatted to FAT12 before the bootloader is installed and booting from floppy works again.
  • OemName in boot sector is no longer overwritten.
  • Volume Boot Record only is now an install option so that the MBR will not be overwritten.

Core Functionality

Audio/Video Stack

Kernel Streaming

PORTCLS

  • Status codes of unhandled IRPs are no longer modified.

Filesystems

CDFS

  • Reading along non-aligned blocks has been fixed.

ACPI

  • ACPICA updated to 20110922.
  • Special devices are now identified with unique IDs.
  • Physical address retrieval has been implemented.
  • Reading and writing PCI configuration mistakenly interpreted a value representing bits as representing bytes, causing memory corruption and overreads. This issue is now resolved.

Plug n Play

  • IRPs sent to PnP devices during enumeration are now compatible with XP/2003/Vista.
  • Duplicate loading of drivers is now properly resolved.

  • IopDecrementDeviceObjectHandleCount, IopInterlockedIncrementUlong, IopInterlockedDecrementUlong, IopNotifyAlreadyRegisteredFileSystems, and IoEnumerateRegisteredFiltersList functions implemented.
  • Additional I/O device registration and removal functions relating to storage devices have been implemented.
  • The kernel now handles unexpected device removals.
  • Removal of locks when debug information is associated is now fixed.
  • The correct number of serial ports is now registered in the global configuration table.

  • Data is no longer corrupted when the receive buffer is smaller than the incoming data.
  • Events whose conditions have already been fulfilled before a wait operation was called are immediately notified now.
  • AFD now immediately listens for new connections instead of waiting for the current connection to be accepted, helping increase throughput.

  • Start menu initialization has been improved to better show what fails.
  • A ReactOS registry key is used for ReactOS specific features.

Startup/Shutdown

  • FreeLoader no longer allocates entire pages for every small memory allocations, reducing fragmentation and overall memory usage during booting.
  • A variety of fixes for dealing with bios memory maps. These maps could have a range of problems including invalid entries, overlapping regions, and not aligning entries along page boundaries. FreeLoader also no longer overwrites itself when loading the HAL due to invalid memory maps.
