[New-bugs-announce] [issue12386] packaging fails in install_distinfo when writing RESOURCES

[Vinay Sajip]

New submission from Vinay Sajip <vinay_sajip at yahoo.co.uk>:

This part of install_distinf.run():

    if install_data.get_resources_out() != []:
        resources_path = os.path.join(self.distinfo_dir,
                                      'RESOURCES')
        logger.info('creating %s', resources_path)
        with open(resources_path, 'wb') as f:
            writer = csv.writer(f, delimiter=',',
                                lineterminator='\n',
                                quotechar='"')
            for tuple in install_data.get_resources_out():
                writer.writerow(tuple)

fails at the writerow line:

I think the open(resources_path) should use 'w' rather than 'wb' as the open mode.

Relevant part of setup.cfg:

resources =
    virtualenvwrapper.sh = {scripts}

I know I can put it in the scripts = section, but I'm testing having something in resources, which ought to work ...
