Planned services downtime
by Pierre Schweitzer 03 May '13

03 May '13

Hi, on the 3rd of May, from 1PM to 6PM CET, the following services will down due to a power maintenance: -> ISO upload -> ISO download -> Doxygen -> cppcheck -> Linux buildbot -> KVM testbot -> VMware testbot I warmly recommend you don't commit during that period then, as remaining builder, Windows one, won't be able to upload its ISOs. Actually, I could also take the opportunity of such downtime to take SVN (svn, git, buildbot master) server down for maintenance as it will barely harm. I'll keep you informed. I'll push reminders before it happens. Sorry for the services interruption. With my best regards, -- Pierre Schweitzer<pierre at reactos.org> System Administrator ReactOS Foundation

Hello, Let me invite you to the monthly status meeting taking place last Thursday of this month, 25th of April, 19:00 UTC. The meeting will be at irc://dev.reactos.org (Port 6667, no SSL) in the channel #meeting, or as Pierre says. 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, and they are going to be different once again as they are not stored in any database. Hopefully it's not much of inconvenience. If someone still is not getting passwords sent before a meeting - please email Colin or Pierre before the meeting started to get one.

KVM testbot upgraded
by Pierre Schweitzer 10 Apr '13

10 Apr '13

Hi guys, the KVM testbot has been upgraded from 0.12.3 to 1.0. This means that you could find new regressions. On testman, the starting revision at which it has been used is: 58727. It's interesting to note that previously the KVM testbot was running headless (no VNC display on ReactOS VM). With newer release, this is impossible. Either ReactOS or KVM locks up because of this. See: http://build.reactos.org/builders/Linux_AMD64_1%20KVM-Test/builds/2710/step… With my best regards, -- Pierre Schweitzer<pierre(a)reactos.org> System Administrator ReactOS Foundation

Future merge of the ros-csrss branch into the trunk
by Hermès BÉLUSCA - MAÏTO 09 Apr '13

09 Apr '13

Hi all ! I'm writing this mail to announce to you that in one week (if everything works as expected till this time) I will be ready to merge my ros-csrss branch into our current codebase. The ros-csrss branch (http://svn.reactos.org/svn/reactos/branches/ros-csrss/?view=log) was started 5 months ago (October 14, 2012 to be precise) with a three-fold purpose: - Use the new Windows-compatible Client-Server Runtime Subsystem (csrss + csrsrv) written by Alex Ionescu, unused at the moment and which currently lives in trunk/reactos/subsystems/csr/, and as such was a replacement for the older one in trunk/reactos/subsystems/win32/csrss/. This last one was progressively hacked to include functionalities from the new csrss; however most of the old code remained and as such it was a big hack. Also the CSR client part, residing in ntdll, was updated (thanks to comments put by Alex inside it). To communicate between the server-part and the client-part, some messaging protocol is used (thanks to LPC); the used structures were not so up-to-date, but the new ones were in the code, not used. So I could use them instead of the older ones. That meant that some work was needed in ntdll (as previously stated). Disregarding the details (you can see them in the commit log), I also had to rework a little bit on the dlls which communicate with CSR, namely kernel32. - Replacing our very old win32csr.dll csr server by the collection basesrv / winsrv as it is done under Windows. For that I tried to match accurately our existing code with what should exist on Windows according to this list of CSR servers APIs : http://j00ru.vexillium.org/csrss_list/api_list.html . - Since the console subsystem is (for historical purposes on Windows) the only subsystem which exploits all the possibilities of the CSR, much of the work in the branch was done to make it working with the new csrss. Even if on Windows it is included together with other APIs inside the winsrv dll (since Windows NT 3.1 release), I decided to put it in a separate dll, called consrv, on ReactOS (I took the name from the dll where it was included in Windows NT 3.1 beta from October 1991). Also, because I believe that the console subsystem is something that, on Windows, was somewhat neglected (no ANSI control, (almost?)no TTY-like flavour...) I decided to work on its internal architecture (the exterior one being unchanged for compatibility reasons) such as to exacerbate the following things: * the "console server" which dialogs with the console applications, and which maintains a list of all the created consoles. * different "front-ends" corresponding to where you want to output the information (~= console hardware) (it is of course work-in-progress). At the moment only one is working: the GUI console. I have to make the TUI interfacing correctly with the rest of the code (but since it's not used for now, it's not extremely urgent). The idea would be to have also a front-end for serial ports, so that we could interact with the serial port (with Putty if running ROS on a virtual machine, or with a serial console, etc...). And another idea would be to make those front-ends dynamically-loadable (instead of being compiled inside consrv). - I also fixed some parts of the console properties dialog box. Here is the JIRA report for the merge: http://jira.reactos.org/browse/CORE-7002 Here are the test results with revision 58723 (plus comparison with revisions 58722 and 58720): http://old.reactos.org/testman/compare.php?ids=16213,16218,16219,16221 You will see that the ntdll:exception seems to run 24 more tests, but 4 failed compared to non-patched r58723. The errors are "exception.c:821: Test failed: Eip at 0x77f2b2a3 instead of 0079000B". It would be interesting to investigate further on these failings. Also, gdi32:font executes 33 more tests, and 10 more fail, due to the Fixedsys font. A problem, already existing in trunk, remains: http://jira.reactos.org/browse/CORE-6397 (see description inside). You are encouraged to make comments, etc... etc...
