Re: [ros-dev] [ros-diffs] [jgardou] 65210: [NTOS/PS] - Do not leak a reference to the process object when setting quotas.
by Timo Kreuzer 03 Nov '14

Doesn't this change Windows behaviour? No, luckily it does not change *Windows* behaviour. It does not even change ReactOS behaviour, but only, because it was already broken before. Since MS implemented this function in an arbitrary and hard to comprehend way, we need to follow this pattern. This means, the function must not fail on process reference failure, unless certain conditions are met, otherwise we will fail with the wrong Status code. To fix the situation, we could remember the fact that the process couldn't be referenced (possibly by setting Process to NULL) and later check that after other checks were done. The alternative is referencing the process individually in each and every case, which will make the function even more huge and does not really help with it's readability. Or we can factor our each case and implement it as a separate function. It would add a lot of code duplication, but might help a bit with readability and maintainability.

Fezile server downtime this evening
by Colin Finck 03 Nov '14

03 Nov '14

Hi all, Jan and I will finally install the remote management card in Fezile this evening and verify the cabling of our UPS systems. This will cause a short downtime of the Fezile server along with its testslaves, cppcheck, Doxygen, Git and iso.reactos.org. In case we notice a fault in UPS cabling, we may also be required to temporarily shut down other servers, replug their power cables and boot them up again. This may cause very short downtimes as well. After this measure, we will be able to totally manage this important server remotely, even if its OS has failed at some point. Proper UPS cabling also ensures smooth operations in case of sudden power outages. Thanks for your understanding! Cheers, Colin

It should at least be min(DeviceExt->NtfsInfo.BytesPerFileRecord, Stack->Parameters.FileSystemControl.OutputBufferLength) in the memcpy size. Or am I missing something?

Both puts and LocalFree should only be executed if AllocAndLoadString succeeds (but return FALSE in either case). Thanks!

BuildBot changes
by Colin Finck 30 Oct '14

30 Oct '14

Hi all, As you can see in project-tools SVN, I've improved our Bash scripts for Buildslaves. They're now also usable under Windows (in a Cygwin environment) and I'm already doing this on our new Windows Buildslave Carrier-Win7. Bash on Windows may look hacky at first, but it's definitely more comfortable than Batch! Moreover, we now only have a single version of build scripts to maintain for all our Buildslaves! This also involved some naming changes on the existing slaves to maintain a consistent scheme. Tell me if anything broke. Bringing all desired Windows builders back will still take some time. I've only started with a RosBE-Windows based one right now and I need your help here: For some reason, VirtualBox 4.3.18 (used for reg-testing) doesn't want to run headless. I can do a 'runas /user:buildbot VBoxManage controlvm "ReactOS Testbot" poweroff' in a CMD and it will work well. The very same command executed through BuildBot ends with: ==================================================================== VBoxManage.exe: error: Failed to create the VirtualBox object! VBoxManage.exe: error: Code E_ACCESSDENIED (0x80070005) - General access denied error (extended info not available) VBoxManage.exe: error: Most likely, the VirtualBox COM server is not running or failed to start. ==================================================================== See http://build.reactos.org/builders/Carrier-Win7%20VBox-Testbot/builds/6/step… VBoxSVC.log isn't touched when BuildBot tries this command, so I have no additional information. Haven't found a solution yet, so I'm asking here if any of the VBox experts know what could be going wrong. Cheers, Colin

Status Meeting (October 2014)
by Aleksey Bragin 29 Oct '14

29 Oct '14

Hello, Let me invite you to the monthly status meeting taking place 30th of October, 19:00 UTC (that's tomorrow!). IRC service will only be started shortly before the meeting. 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. Hopefully it's not much of inconvenience. If someone still is not getting passwords sent before a meeting - please email Pierre before the meeting started to get one. Please send agenda proposals to me before the meeting, so that we can start with a proposed agenda. Regards, Aleksey Bragin
