1254913 - mozbuild includes doesn't seem able to handle symbolic links?

Status: RESOLVED FIXED

(Firefox Build System :: General, defect)

Description

[Benjamin Bouvier [:bbouvier] (inactive)]

My tree looks like this:
- /code/mozilla-inbound contains a clone of the hg repository
- /home/ben/mozilla/repo/ is a symbolic link to /code/mozilla-inbound
- my build script runs /home/ben/mozilla/repo/js/src/configure in my build dir.

What I get, since this morning (UTC+1 time):

mozbuild.configure.ConfigureError: Cannot include `/code/mozilla-inbound/browser/moz.configure` because it is not in a subdirectory of `/home/ben/mozilla/repo` 

It was working like a charm yesterday, so I guess this is something new.

Changing my build script to run /code/mozilla-inbound/js/src/configure works around the issue.

Is it that mozbuild can not handle symbolic links? If so, could it?
