Status Meeting (April 2017)
by Aleksey Bragin 24 Apr '17

24 Apr '17

Hello, Let me invite you to the monthly status meeting taking place 27th of April, 19:00 UTC. We do it either in #reactos-meeting on Freenode, or on a very own standalone IRC server. In that case your participation passwords and server address will be emailed to you shortly before the meeting starts, and they are going to be different once again as they are not stored in any database. And everyone is fine with that. Please send agenda proposals to me before the meeting so we don't waste time trying to setup the agenda directly during the meeting. Regards, Aleksey Bragin

retiring 'shellext/slayer'
by Mark Jansen 22 Apr '17

22 Apr '17

The shell extension 'slayer' will soon be removed. It has been surpassed by the shell extension 'acppage'. Since neither of the modules is yet active, this should not pose a problem. Related issues: CORE-10375 and CORE-13111 Regards, Mark.

Test KVM AHK Bot Upgrade
by Sylvain Petreolle 18 Apr '17

18 Apr '17

Hello all, I'm currently upgrading my AHK Testbot to Fedora 25, 24 only receives backports and Fedora 26 is already on the way. I never upgraded it before, so I don't know if it will take one or several hours to be back online. Kind regards, Sylvain Petreolle

Re: [ros-dev] [ros-diffs] [tfaber] 74305: [NTOS:KE] - Gracefully handle page faults during V86 code execution. This is a bit of a hack because with our limited use of V86 code it is unclear how a page fault can even occur. ...

So why implement this code path if we have nothing that hits it?

Re: [ros-dev] Definite Decision about ISO lifetimes at iso.reactos.org

Am 16.03.2017 um 00:00 schrieb Giannis Adamopoulos: > I was wondering if it is possible to delete every second iso instead of purging all isos before some time? That's a good idea and makes sense for the bootcd-dbg ISOs. So my final proposal is this one: bootcd-dbg: 5 years (after that every second ISO is purged) bootcd-dbgwin: 0.5 years bootcd-rel: 0.5 years bootcdregtest: 1 week livecd-dbg: 0.5 years livecd-dbgwin: 0.5 years livecd-rel: 0.5 years I'll be away until the beginning of April, so there is enough time for any objections. Otherwise, it will be set up exactly this way when I'm back. - Colin

Building/Testing infrastructure back on steroids!
by Colin Finck 09 Apr '17

09 Apr '17

Hi all! As of today, our high-performance servers Carrier, Mothership and Testee are finally back in service for building and testing! They take over many tasks from HotelLux, the generously provided server from Aleksey, which had to bear the load of previously 3 separate machines for over a year. You should notice faster builds on the Windows buildslaves, a returned VBox testslave, and more reliable ISO downloads. The VMware testslave is not back yet, but I'll be reinstalling this one as well. In June, we also plan to upgrade our best-performing server even more, using the donated 64GB of RAM and CPU upgrades that are cheaply available these days. This should decrease build times even more! Cheers, Colin
