Arwinss
From ReactOS
Arwinss is an alternative implementation of the core Win32 subsystem components. Technical information about implementation details is available at this page: Arwinss technical.

Usage
Checkout the arwinss branch (svn://svn.reactos.org/reactos/branches/arwinss/reactos), and compile using following command:
makex comctl32 user32 gdi32 win32k winent win32csr freetype kernel32 explorer winlogon
This will build all needed modules of a new subsystem, which you need to copy over to the installed ReactOS version (see Transfer files from the host OS to the virtual drive).
If you want to build winex11 module, you need to firstly copy lib/3rdparty/libX11/libX11.a file from your working copy to the obj-i386/lib/3rdparty/libX11 directory (creating it if it does not exist). This will fix the winex11.drv linking issues, and you can just type
makex winex11
to build this optional module.
Architecture
Arwinss uses parts of the Wine architecture and parts of Windows NT architecture in appropriate places and in a good way.The overall call flow / architecture of Arwinss looks like this:
It consists of the following modules, one of them being optional (winex11.drv):
- dll/3rdparty/freetype - implements usermode font rendering (FreeType library, with small ReactOS glue), used by GDI32.DLL
- dll/win32/user32 - implements USER API
- dll/win32/gdi32 - implements GDI API
- dll/win32/winent.drv - implements native graphics and user drivers
- dll/win32/winex11.drv - implements X11 X-windows graphics and user drivers
- subsystems/win32/win32k - implements kernel mode counter part of the native graphics driver, a Simple Window Manager (SWM) and a kernel mode USER server.
- subsystems/win32/csrss/win32csr - implements needed parts of the CSR subsystem along with handling user input
Hacking
Most of the hacking happens in WINENT.DRV and WIN32K.SYS, with very rare fixes to the user32/gdi32 (mainly, because it's a tested Wine's code with only minor changes).
Convention for marking changes. C++ code comments (//) mean that the place has some special mark up for debugging. A typical use is for a
// FIXME: Something
Potential Benefits
These bugs would be fixed if Arwinss was ready (just a short list):
| ID | Resolution | Summary (9 tasks) ⇒ |
|---|---|---|
| 1175 | comctl32: listbox does not hide scrollbars in listbox | |
| 1776 | Microsoft remote desktop client: computername can't be entered | |
| 2428 | Nonstop scrolling hangs entire GUI | |
| 3500 | charmap: redrawing bug | |
| 4612 | Tn5250: can't move window | |
| 5069 | Image (scaling) artifacts in MSI installers | |
| 933 | OpenOffice: v 1.x.x displays garbled text in setup and app itself | |
| 1239 | PATCH: winamp: main window partially drawn | |
| 4443 | FIXED | Firefox 3.0.5 - Can't scroll page with mouse wheel. |
As one can see from these bug titles it mainly boils down to drastically improved user32 and gdi32 support.
