Re: [ros-dev] Microsoft switched to Git

Sounds like a bug in their migration/etc tool. MS has history going back to 1984 and migrated everything to Git with zero problems. At some point you should apply Ionescu's Razor: "Hmmm, a company of 150,000 developers and the most complicated and oldest series of repositories in the world, was able to move to Git, including while employing people who have been there for 30 years and used to other, older systems.... but 30 open source developers can't make that change because X". It follows from this that X is bullshit. On the polluting history, again, just read commits that have [FOOBAR] in them, and ignore others. Write a post-commit hook to rewrite/squash them.

JIRA/FishEye upgrade on March 8
by Colin Finck 18 Mar '17

18 Mar '17

Hi all! Let me announce a definite date for our JIRA/FishEye upgrade: Wednesday, March 8, around 9:00 UTC Expect downtimes of several hours at https://code.reactos.org and https://jira.reactos.org around this time. I can say for sure that I will have enough time on this day and the following to deal with all possible incidents that could happen during the complex upgrade. This also allows me to get direct in-person feedback from all the devs attending CLT on the weekend after that :) The upgrade to JIRA 7.x is a major one, and Atlassian recommends everyone to have a look at the new features: https://confluence.atlassian.com/migration/jira-7/server_jira_product-chang… Best regards, Colin

That patched result has "OUT OF PAGED POOL" errors. Is the cache too large? Or are there any leaks?

Status Meeting (February 2017)
by Aleksey Bragin 23 Feb '17

23 Feb '17

Hello, Let me invite you to the monthly status meeting taking place tomorrow, 23rd of February, 19:00 UTC. 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. Alternatively we'll do it in #reactos-meeting on Freenode, depending on our admins mood. 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

Office (Excel, Word...) 2010 on ReactOS
by Hermès BÉLUSCA-MAÏTO 22 Feb '17

22 Feb '17

Hello everyone, Today I was finally able to finish the installation of Office 2010 in ReactOS, using as a temporary measure the Wines NTLM layer that calls into the ntlm_auth utility of Samba. This was done while Samuel is completing his NTLM implementation. As this wine layer is here running on ReactOS, few modifications were needed, and I also needed to find a Windows build of Samba. Ive found one, by chance, at http://smithii.com/samba . Then, using ReactOS revision 73868 (or later), and using this version of Samba, the Office installation finishes (reminder: the problem was due to the fact the installer needed NTLM to communicate with the Office Software Platform Service, OSPPSVC.EXE). We are now able to use Excel, Word, on ReactOS, as shown in this picture: http://i.imgur.com/fLEwoVI.png There are now 2 main problems: - NTLM should be correctly implemented; - There are an awful lot of drawing problems with Office 2010 applications (similar to those of Office 2007 apps): for example, dragging the graph downwards shows his frame going upwards; there are many black regions that show up, etc...: It seems we have problems in coordinate frames. And other problems too. Also, we have some mouse capture problems: if you try to redimension the windows the normal way (bring mouse cursor on top of the border, left-click-maintained, move mouse, release left button), and then move the mouse inside the window, it continues to be redimensioned... As a result, I took ~=15 minutes to make this simple trivial picture above, almost all the time taken to fight against window dimensioning & the drawing problems. But anyways, enjoy ! This will be part of my next blog report. Cheers, Hermès
