[bitbake-devel] Question about the setVar method

[Kuhl, Brian]

I'm working on a new bitbake class which includes the following function which works as desired except the
d.setVar( dict[cmd],retlist[0])
function does not appear to have global scope, and its effects are not seen outside the function.
How do I give this operation global scope?

python rpm_spec_do_postpatch() {
               import subprocess
               dict = {'DESCRIPTION':'DESCRIPTION',
                                             'LICENSE':'LICENSE',
                                             'SUMMARY':'SUMMARY',
                                             'URL':'HOMEPAGE' }

               harvest_spec = d.getVar('HARVEST_SPEC', True)
               if harvest_spec :
                              pn = d.getVar('PN', True)
                              workdir = d.getVar('WORKDIR', True)
                              src_spec = d.getVar('SRCSPEC', True)
                              rpm_args = d.getVar('RPM_ARGS',True)
                              spec_path = os.path.join( workdir,src_spec )
                              prefix = "rpm -q %s --specfile %s --qf '%%{" % (rpm_args,spec_path)
                              postfix = "}<:>' "
                              for cmd in dict:
                                             cmd_str = prefix + cmd + postfix
                                             retstr = subprocess.check_output(cmd_str, shell=True)
                                             retlist = retstr.split('<:>')
                                             if retlist[0]:
                                                            d.setVar( dict[cmd],retlist[0])
                                                            bb.data.update_data(d)
                                                            bb.note ("rpm_spec_do_postpatch HARVEST_SPEC setting  %s in %s to: %s \n" %( (dict[cmd]),pn,retlist[0]))

}
