Monthly meeting - August 2012

by Aleksey Bragin

Hello, Let me invite you to the monthly status meeting taking place last Thursday of this month, 30th of August, 19:00 UTC. The meeting will be at irc://fezile.reactos.org (Port 6667, no SSL) in the channel #meeting, if the server works. If not, then an alternative place will be announced here. Note that the IRC service will only be started shortly before the meeting. Your participation passwords will be emailed to you shortly before the meeting starts. If someone still is not getting passwords sent before a meeting - please email Colin or Pierre before the meeting started to get one. In order to save time, let's choose who is going to be the minute taker on the upcoming meeting. As usual, Z98 is welcome to volunteer. The agenda will be posted shortly before the meeting, suggestions are welcome (send them to my email as usual). With the best regards, Aleksey Bragin.

Re: [ros-dev] [ros-diffs] [jgardou] 57171: [MINGWEX] - mark DllMain as a weak symbol for GCC. - supply a stubbed DllMain for MSVC. - DllMain is optional, and some DLLs don't implement it. That doesn't mean that they have no...

by Timo Kreuzer

Hi, I don't agree with these changes. If we need a DllEntry in the lib, then we should use the one that is provided by mingw-w64 (all this code is 100% mingw-w64). It simply returns true (thats exactly what the one in MS CRT does) and works for gcc and MSVC. Also what's the point of DisableThreadLibraryCalls() here? As you wrote yourself, no DllMain only means "I have nothing more to initialize than the CRT". But this disables the CRT thread initializion, too. There is also no need for weak symbols, we can simply call the stub DllMain, since it doesn't (shouldn't) do anything.

Re: [ros-dev] [ros-diffs] [tkreuzer] 57141: [FREELDR] Improve readability of sector calculation

by Timo Kreuzer

Btw, we are using a lot of hardcoded 512 values here for sector size even though there is a field in fthe Volume structure for that. Is that correct?

Good bye RBuild

by Pierre Schweitzer

Hi, after having finished its 11405th build, the last official RBuild builder has gone offline, forever. The Linux CMake builder has now turned as being the official builder. Thanks RBuild, you served us well :-). Also, the other RBuild builder, the release builder has also gone offline forever. Its hardware was not able to properly handle a ReactOS build, and was hardly upgradable. Daily release builds should replace it any time soon. With my best regards, -- Pierre Schweitzer <pierre(a)reactos.org> Systems Administrator ReactOS Foundation

by Timo Kreuzer

Hmmmmmmm.... I don't think that this is a good idea. We must call DC_vPrepareForBlit to lock the surfaces, otherwise we run into race conditions. And we should really also care for the mouse cursor, otherwise we might make it unhappy.
