2013-02-11lib/oe/path.py: support missing directory components in realpath()Enrico Scholz
Some use cases in OE operate on symlinks which dangling path components. Assume that these are directories instead of raising ENOENT. Signed-off-by: Enrico Scholz <enrico.scholz@sigma-chemnitz.de> Signed-off-by: Richard Purdie <richard.purdie@linuxfoundation.org>
2013-02-11lib: implemented oe.path.realpath()Enrico Scholz
Various parts of the buildsystem have to work with symlinks. Resolving them is not trivial because they are always relative to a sysroot directory. Patch adds a function which returns the destination of a symlink by assuming a given path as the / toplevel directory. A testsuite was added too.
