I tried pushing a patch to the xmonad-contrib repo today and got the following error: darcs: takeLock /home/srv/code/XMonadContrib/_darcs/lock in /home/srv/code/XMonadContrib: atomic_create /home/srv/code/XMonadContrib/_darcs/lock in /home/srv/code/XMonadContrib: permission denied (Permission denied) Anyone have any ideas about the cause? -Brent

Remains from the hack attack of c.h.o. Apparently no one has verified XMC was not tampered with and has made it writable. This has been causing trouble for weeks/months. -- gwern http://www.gwern.net

I see. So who has the ability/permission to do this? -Brent

I believe keys are unchanged, so committers can ssh in and remove the lock. I suppose since it's readable someone's diffed it with an uncorrupted version and determined no one messed with it. If commiters need keys reset or other support, they can email support at community.haskell.org. regards, wmw

That doesn't seem right.

Committers can only modify the files in the XMonadContrib-p group.

Oops, please forgive the misinformation. I've missed a lot of context having been off IRC till recently, and shouldn't have made assumptions about this issue. What attempts have been made to solve the problem? Given that dons and sjanssen have changed their roles, do they need to be involved in altering groups and permissions for the repos? Would a proposal formed by a quorom of those with commit access be enough to request changes on the c.h.o support queue? thanks, wmw One thing I do know is the support email personnel have been very responsive and helpful with issues I've had to resolve on c.h.o.

Hi, I've mailed support@community.haskell.org about this issue over a month ago (February 26), and had dons bring it up with the admins more recently (March 13). Core permissions are fine. Maybe we should just set up an alternate repo somewhere, but then there is the question of updating the website and other documentation that includes the repo url. -- Adam * On Tuesday, March 29 2011, Brent Yorgey wrote:
