MacPorts fails to open a portfile due to denied permissions

[mkae (Marko Käning)]

I recently upgraded to MacPorts 2.0.0.

It looks like I have found a MacPorts permission problem now.

Here is an example of a usual workflow when I work with a local port tree.

• Right at the beginning one sees that the install of kdepimlibs4 fails.

• A look at the log file reveals that MacPorts changes gid and uid to 505 and 511 respectively being the macports user.

• dscl shows that marko has uid 502

• ls -l shows that the Portfile should be readable to anyone, BUT IT ISN'T OBVIOUSLY. :-(

Same basic problem as #26094. I could never reproduce it either…

What are the permissions on /Users/marko/WC/MacPorts/ports/kde/kdepimlibs4?

[mkae (Marko Käning)]

Nothing unusual:

$ ls -la /Users/marko/WC/MacPorts/ports/kde/kdepimlibs4
total 24
drwxr-xr-x   5 marko  staff   170 Jul 24 01:01 .
drwxr-xr-x  15 marko  staff   510 Jun 19 13:00 ..
-rw-r--r--   1 marko  staff  1220 Jul 18 19:31 Portfile
-rw-r--r--   1 marko  staff  1220 Jul 18 17:26 Portfile.my

[pixilla (Bradley Giesbrecht)]

I was wondering if the permission on the directory /Users/marko/WC/MacPorts/ports/kde/kdepimlibs4 had ugo+x so everyone could access.

[pixilla (Bradley Giesbrecht)]

Can you quite Terminal.app, relaunch Terminal.app and do:

$ ls -la /Users/marko/WC/MacPorts/ports/kde/kdepimlibs4
$ open /Users/marko/WC/MacPorts/ports/kde/kdepimlibs4

Verify that the file Portfile actually exists.

Workaround is setting macportsuser to root.

I see, well, I've found now why it happens. A directory higher up had too restrictive permissions which is why this was bound to fail. See my comment in ticket #26094!
