[bitbake-devel] [PATCH 1/1] cooker.py: change working dir before use pyinotify

[Robert Yang]

Fixed:
$ cd tmp/work/core2-64-poky-linux/bash/4.3-r1
$ bitbake bash -cclean

ERROR: Running idle function
Traceback (most recent call last):

                 else:
  File "/usr/lib/python2.7/posixpath.py", line 347, in abspath(path='./build'):
             else:
    >            cwd = os.getcwd()
             path = join(cwd, path)
OSError: [Errno 2] No such file or directory

And we can't run bitbake again:
ERROR: Only one copy of bitbake should be run against a build directory

Chaneg working dir to TOPDIR rather than the dir which runs the command
will fix the problem. Move self.initConfigurationData ahead, otherwise,
there is no self.data.
