Bug 190144 – PORTDIR as symlink triggers sandbox violation with svn.eclass

• Product: Portage Development
• Status: RESOLVED FIXED

[Description Taylor Braun-Jones 2007-08-25 07:11:07 UTC]

When building mythtv frontendonly I get an access violation error because portage is trying to unpack the subversion source to the wrong place. /usr/portage-mrserver is a NFS mount point. /usr/portage symlinks to it. See the attached error log. My emerge --info is:

This is what emerge -pv mythtv looks like:
trjones@bigbird ~ $ emerge -pv mythtv

These are the packages that would be merged, in order:

No it doesn't try to unpack to a "wrong place", it unpacks to a place you've configured it to unpack. Set PORTDIR="/usr/portage-mrserver" instead of symlinking the thing, that's the whole point why the variable exists.

[Comment 3 Zac Medico 2007-08-25 08:36:15 UTC]

The sandbox doesn't work with symlinks.  I suppose we can export the real path in the ebuild environment, but you can just set PORTDIR="/usr/portage-mrserver" like Jakub said.

[Comment 4 Zac Medico 2007-08-25 19:43:45 UTC]

In svn r7700 it's fixed to use the realpath of DISTDIR.

[Comment 5 Zac Medico 2007-09-07 19:18:22 UTC]

This has been released in 2.1.3.8.
