Bug 450772 – sys-devel/llvm-9999 - subversion: can't fetch to /var/portage/distfiles/svn-src/llvm/trunk from http://llvm.org/svn/llvm-project/llvm/trunk when DISTDIR is on nfs

• Product: Gentoo Linux
• Status: RESOLVED INVALID

[Description Thomas Capricelli 2013-01-07 22:53:31 UTC]

I often use live ebuild, without any problem, but i don't seem to manage to install the live llvm ebuild. It might be because of svn, as i think this is the first live ebuild i try to install that is based on svn. Others are usually using git/hg.

Using :
system : ~amd64 up to date
dev-vcs/subversion : 1.7.7
portage : 2.1.11.38

Reproducible: Always

Ok, here's an information that i think is rather important : my distfiles is mounted through nfs (v3), it is shared by all computers on the local network.

if i unmount it, making portage use a the local disk instead, then it works.

So i guess the bug is now something around "svn live ebuild fail to checkout on nfs-mounted distfiles"

Maybe you don't have locking properly configured for your nfs mount?

Someone reported that enabling the nfslock service solved a similar problem here:

@zac

Good hint!
Lock was configured and i thought it was working. using the very useful python code from http://naf-lhcb.physi.uni-heidelberg.de/index.php?q=node/52
i can confirm locking was broken on my setup.

Once fixed (on the server, i had ALL:ALL in hosts.deny, which requires ALL:localhost in hosts.allow, even though all nfs/lock stuff was already allowed), the previous python code does work, and i can indeed emerge svn-based live ebuild from nfs.

As such, i close this bug as invalid, this is not gentoo's fault :)

Thanks again for the hint.
