parallel @20110602 build failure

[mkb-prime@…]

I get the following error when building parallels immediately after selfupdate. The log says to report this to the upstream maintainer as well, so I will.

I updated parallel to 20110722 in r81179. Does that help?

[mkb-prime@…]

On second thought, I don't think this is a bug in parallel. Rather, it's because of the privilege dropping that's new in MacPorts 2.0. When running as user macports, the build still tries to use semaphores in $ENV{HOME}/.parallel which in my case is owned by me and not world-writable. If I chmod ~/.parallel to 777, the install succeeds. The new version still fails.

Replying to mkb-prime@…:

it's because of the privilege dropping that's new in MacPorts 2.0.

I agree.

[mkb-prime@…]

Patch to fix

[mkb-prime@…]

I got it to work without messing with the permissions in my homedir simply by changing the homedir to ${workpath} during install. Maybe this isn't the right place, but it's a start.

[nerdling (Jeremy Lavergne)]

Patch works for me.

Committed in r81659.

[nerdling (Jeremy Lavergne)]

Further patched in r81666.

[ci42]

Committed a improved patch in r81666 and take over maintainership.
