shell32 vs. shell32_new
by Gregor Schneider 19 May '11

19 May '11

Hi ros-dev, I've seen shell32_new being added into trunk by r51768, but haven't heard of anything else about it. From what I can see it changes shell32 from C to C++, which looks like a good move. Problematic seems to me that it is completely out of sync with trunk's shell32 (judging from the translations alone). It might also be annoying for merging future patches, since the C to C++ move changes the code substantially. So are there any plans concering shell32_new? Do I have to merge all code changes in C and C++ or is shell32(_old) going to be dumped anytime soon? Best regards, Gregor

msports commit (51813) - CMakeLists.txt references nonexistent files
by Adam 18 May '11

18 May '11

When I was trying to build trunk (using Cmake) the configure.cmd did not complete. Host tools were OK but reactos directory was not. I tracked the issue to /dll/win32/msports/CMakeLists.txt which contained references to two nonexistent files (serial.c and parallel.c) and commenting them out allowed the build to continue (albeit with an error at the very end) there.

Hiya Attached, you will find a rough draft of current patch assignment proposals. I`m trying to keep it in realtime, so several of those are already in place. As usual, please comment if you find you shouldn't be reviewing assigned patch. Best regards

Compatibility List moderation
by Javier Agustìn Fernàndez Arroyo 09 May '11

09 May '11

Speaking about bug reports drama, im still watching how there are several people that are still sending totally useless compatibility test results to ROS database... I want to ask for a moderation system for that, and i would want to offer myself to moderate new incoming results, such as Wine system....

Re: [ros-dev] [freeldr] Add PXE "filesystem" (Aleksey Bragin)

Hi Aleksey, I'm sorry if my opinion came across as critique of the work as such. It was definitely not intended that way. I have great respect for all your efforts. Just a point about unfortunate choice of AT&T syntax. I would gladly volunteer to translate all old AT&T code to Intel. After all, I do have 25 years of expertise in assembly coding. It's just that I'm completely bogged down by R.L and have no time. But if it can wait, just leave it be, and I'll do it later. I'm sure Timo has enough to do with other issues already. I abbreviated the pro's and con's to just two points, of which the 2nd applies just to gcc's inline asm syntax. Translating non-inline AT&T to Intel is fairly straight forward. InvalidateHarshMode(TRUE); No offence taken. Best Regards L.

Don’t join complaints if you can’t fix it. (Timo’s point is valid because that’s him who actually > converts this stuff!) > > SetHarshMode(FALSE); > > WBR, > Aleksey.

ReactOS YouTube Channel
by Adam 08 May '11

I noticed this YouTube channel here - http://www.youtube.com/reactosorg - and apparently it seems to have 3 videos about ReactOS on it. Nothing seems to be uploaded to it for a little over 1 year and I was wondering perhaps it wouldn't be a bad idea to upload some videos about various events to it. I suspect a major issue with the lack of developers is lack of publicity and I think this seems like a good opportunity. (note I am not sure if it is the official ReactOS channel or not - if not time to make one - apparently it seems the person who made the channel is displaying the Age as 16 years old)
