With Django 1.11 files get post-processed multiple times

See original GitHub issue

On Django 1.11 I see pipeline post-process the same file to the same hashed version multiple times and in the end I have 2 different files e.g.

media/admin.min.70004aec9612.css
media/admin.min.3719a5a090af.css

That does not happen on Django <1.10

example snippet of a my config:

         'admin_min_css': {                                             
                'source_filenames': (                                      
                'js/libs/chosen/chosen.css',                           
            ),                                                         
            'output_filename': 'admin.min.css',                        
         },

Anyone else experiencing that? Possibly related to the introduction of storage.ManifestStaticFilesStorage.max_post_process_passes in 1.11

I confirm this error with Django 1.11.10. I see pipeline post-process the same file multiple times.

Post-processed 'bower_components/bootstrap/dist/css/bootstrap.css' as 'bower_components/bootstrap/dist/css/bootstrap.60711a51db5e.css'
Post-processed 'bower_components/bootstrap/dist/css/bootstrap.css' as 'bower_components/bootstrap/dist/css/bootstrap.cb8a77bb5700.css'
Post-processed 'bower_components/bootstrap/dist/css/bootstrap.css' as 'bower_components/bootstrap/dist/css/bootstrap.3c7be87695cb.css'

after a while, this error comes up:

Post-processing 'All' failed!

I use S3BotoStorage.

When using S3 if query-string authentication is enabled, you can end up in a situation where CSS files contain URLs with query-string parameters such as AWSAccessKeyId=...&Signature=...=&Expires=... – and each time each file is hashed, these can change, creating an endless loop of differing hashes. Turing AWS_QUERYSTRING_AUTH off might help.
