Only works with AWS_PRELOAD_METADATA=True

[alanjds]

It still copies over everything if AWS_PRELOAD_METADATA=False, as storage.entries is empty in this case.

I dont know how to solve it yet.

That's true. However, without preloading the metadata it would need to make a separate request to S3 per file to check if it that file needs to be updated. That should be a little faster than uploading all files, but maybe not much faster.

I am thinking in a way to force to preload_metadata if is not set, but only for collectstatic command...

[alanjds]

My problem is that letting AWS_PRELOAD_METADATA=True eats about 2sec from my Heroku dyno startup. This is a lot for me.

[olofsj]

I see. Preloading the metadata only in the collect static command sounds like a nice idea. Let me know if you get it working.

[olofsj]

I think I found an easy way to always preload the metadata in the collect static command, even if AWS_PRELOAD_METADATA=False. Please try bd79483 and see if it works for you.

Thanks. It worked. In the meantime I had implemented the same here.

I think its better to log the change... Sent a pull request.
