Improved packager.compile() to handle s3 storage when compiler generates output to the local one.

[thomasyip]

This patch resolves the problem by copying the compiled file into the packager (s3) storage.

If someone needs urgents fix like me:

monkey patch:

app/init.py:

# Fixes S3 for pipeline...
from pipeline.packager import Packager
from django.contrib.staticfiles.finders import get_finders, find


def __monkey_compile(self, paths, force=False):
        paths = self.compiler.compile(paths, force=force)
        for path in paths:
            if not self.storage.exists(path):
                if self.verbose:
                    print("Compiled file '%s' cannot be found with packager's storage. Locating it." % path)

                source_storage = self.find_source_storage(path)
                if source_storage is not None:
                    with source_storage.open(path) as source_file:
                        if self.verbose:
                            print("Saving: %s" % path)
                        self.storage.save(path, source_file)
                else:
                    raise IOError("File does not exist: %s" % path)
        return paths

def __monkey_find_source_storage(self, path):
    for finder in get_finders():
        for short_path, storage in finder.list(''):
            if short_path == path:
                if self.verbose:
                    print("Found storage: %s" % str(self.storage))
                return storage
    return None


Packager.compile = __monkey_compile
Packager.find_source_storage = __monkey_find_source_storage

+1 Works well for me!

[coveralls]

Coverage decreased (-1.1%) to 80.573% when pulling 0b4bf7b on beedesk:master into f004181 on jazzband:master.

[sowinski]

What need to be done to apply this fix to this branch? Is there a fork which is allready working?

[sowinski]

@cyberdelia
Does it mean that it will work with the code from the master branch now?

EDIT:
With the current master branch it works perfectly:
pip3 install git+https://github.com/jazzband/django-pipeline.git@c85a2572e53218716359126d9465cc63447817e5
