Why don't you fix them in the hostilix branch and submit your changes back to ROS?

DIB code generator
by Ge van Geldorp 08 Jul '05

08 Jul '05

One of the things which has bothered me a bit is the code duplication we have in our DIB engine (subsys/win32k/dib). Most of the BitBlt routines in there are very similar. With the recent interest in optimizations a bunch of new (almost identical) routines were added. Don't get me wrong, I'm not saying that adding those optimizations was a bad idea, I'm just pointing out that we have a lot of code duplication. There are 256 possible ROP codes, we support 1bpp, 4bpp, 8bpp, 16bpp, 24bpp and 32bpp, so in theory there could be 1536 routines with basically the same structure. I've been playing around with the idea to write a code generator which would generate the source code for those routines. That would cut down on the duplicated source code and associated maintenance problems (you only need to change the code generator) while still allowing optimized code for each individual ROP code. Just to give you an idea what such a code generator would look like, I've attached my first attempt. Please note that it doesn't really try to optimize the generated code yet, it's just to give an impression. The code generated (16bpp only atm) is rather large, you can get it from ftp://ftp.geldorp.nl/pub/ReactOS/dib16gen.c if you like (or compile the code generator ("gcc -o gendib gendib.c") and run it). A possible problem is that the generated code is quite large. When using the generated 16bpp code, size of win32k.sys increases by about 350kb. Extrapolating this for all bpps, it would mean that win32k.sys would triple in size. So, I'm wondering what you guys are thinking. Should we basically trade memory for speed? Problem is that I can't quantify the speed increase at the moment. Gé van Geldorp.

A few bugs
by Rafal Kupiec 07 Jul '05

07 Jul '05

1) Task manager displays closed / killed software too. Maybe it cannot kill software? Runned software window disappears but in task manager it on runned application list. There's no info about this software in process tab. 2) In browse window I cannot enter in folders. System want to change its name when I double click on it. 3) In Task Manager there's 2x Windows posision in menu (sometimes).

I was wondering what software was being run on the ReactOS machine. I know that it is a version of linux and I guess php and mysql. Are there any others?

Branch for the 0.2.7-Release approaching
by Robert Köpferl 06 Jul '05

06 Jul '05

Hi, the date of the branch for the 0.2.7-release is fastly approaching. I dated it for Monday, 11.06. So there's still over one week ahead. I please you to stop implementing new features but and finish bigger reorganizations in the code. Keep the checked in code compileable. If you have issues concerning the date of the branch, post a message. More or less for my own (but also from comments on the ml) I decided to do a just normal release with normal names. So there will be no "network preview release" or such kind.

Whats happening with this? It seems to have died a death again. Can we appoint some more people to the web team as there have been some great ideas put forward, but nobody seems to be acting on them.
