None of the file types here are actually processed by our static asset
pipeline in a way that would result in the hash-named versions of the
files (stored in staticfiles.json) being accessed. (If they were,
we'd be using something like `render_bundle` to access their paths).
So, we should not be generating/shipping these hash-named versions of
image, audio, and locale files.
This change decreases the size of a Zulip release tarball from 153MB
to 93MB, by removing all of the duplicated copies of various asset
files.
This may also help with #10038, but I'm not marking it as completing
that issue yet, because part of #10038 is that the non-hash-named
image files in prod-static/generated/emoji do not seem to have been
properly overwritten on upgrade, and it's unclear why.
Fixes#5971.
What was happening before is that we built the webpack bundles in
tools/minify-js with nicely hashed filenames, and then `manage.py
collectstatic` was extending these filenames with a second hash
through the use of storage.
Removing the first one didn't seem ideal, but would probably have
worked, but seems confusing for people only familiar with webpack
(ideally, we want the Django toolchain piece to be increasingly
invisible as we replace it).
And we can't exclude the webpack bundles from being processed by
storage, since we need these bundles to be included in the manifest.
So, instead, we set the hash function to be a no-op for the bundle
files.
Fixes significant portions #5971.
More work is required to deal with versioning for some of the
image/font assets.
