Re: [ros-svn] [hbirr] 17538: Fixed a bug in RtlLeaveCriticalSection. We have only to signal the event if someone waits on it.

by Thomas Weidenmueller

hbirr(a)svn.reactos.com wrote: > Fixed a bug in RtlLeaveCriticalSection. We have only to signal the event if someone waits on it. I believe this change is incorrect. This change introduces the exact same bug I fixed in r14326. The reason why this change is incorrect is, that you can't rely on LockCount. It may be incremented anytime a thread enters a critical section and waits for it. That's why there's the RecursionCount field, it is the only information we can rely on to determine whether we're about to release the lock or not. In this code path we already know that we left the last recursion, so no matter what the LockCount is at the moment (depends on how many threads are waiting for the critical section), we always need to unwait one waiter! This change most likely will introduce a dead-lock of cygwin. Best Regards, Thomas

Re: Re: [ros-dev] reactos.com or reactos.org?

>major Operating System manufacturer uses .org as their domain suffix. >Microsoft.com, Apple.com, Redhat.com. Given .ORG should be considered ROS is not a manufacturer, not a company, actually ROS community is a part of ReactOS source code and must be located at sourceforge. Will they register "dot sf" as a first level domain?

Re: [ros-dev] reactos.com or reactos.org?

by yash

My humble point is like this. Once ROS get's to it's first production release, you'll get many commercial offers and may need .com site for doing some commerce, like selling CD's and rotating ads. So many end users will come for download and support. Is it FreeBSD or RedHat way? Turning into monster is no good, but ROS might get huge end (very end) user hit, it is not freebsd and not even linux, it positions as a replacement for windoze itself and windoze means so much commercial and end user.... Yet my personal vision is to have www.reactos.com displaying "Server not found". So you gogo google and type reactos and if you're lucky you get to reactos.org and think "oh dear it is so cool and open source". >I was wondering if, together with the launch of the new website, we should >switch our "primary" domain from reactos.com to reactos.org?

Thanks Jim, I passed your regards on to the development team. I think sometimes we forget the great promise that ReactOS holds, but then someone like yourself reminds us.

ROS-release prepared

by Robert Köpferl

Hi, I prepared a distribution of ros 0.2.7 release. However, I have no good feeling. Not very reproducable (at least I didn't get the rule, yet) it makes problems in qemu. -Sometimes the setup without format doesn't work (crash) -Then the creation of some hive didn't work -> freeldr can't boot -Install works, boot fails At least I have an archive with qemu and working 0.2.7 Maybe that's all related. Possibly am I operating at some limit. Moving the mouse fills up the last bit of memory. Actually, however, if this is the same on our customers pcs, I don't like the idea of delivering that...

ReactOS 0.2.7 setup bug

by Lucio Diaz

Tested in real software. Sintoms: Setup start loading files, after the load a blue screen with the sentence "reactos setup" and two red lines appears in the top and the system lights become busy. After ten minutes of business nothing have happened and the bloq num keys of the keyboard are blocked (no light) so a hang or eternal cicle must be suspected. This computer used to load 0.2.5 (no hardware changes that i know, only software ones) Hardware: Semperon 2800+ 2 Ide HDD -Linux in the second (master boot record of the computer is here) with Grub loading both Suse and Yoper.(Filesystems a bit complex layout: fat, ext2, ReiserF, swap) -Windows 98 with a screwed MBR cause on installing grub i selected the wrong HDD once and my reactos loader was overwriten with grub.(all fat) A PS2 mouse and a PS2 keyboard. Gygabyte 2004 RZ mainboard with integrated ethernet and sound. Winfast graphic card. Realtek netcard (dont remember the model). DVD writemaster CD burner polaroid Any idea?
