Not a Horizon bug, instead it's an Apache 'Works As Intended'. Let me explain how Apache web-server works in conjunction with django- compressor package.
First, Apache serves dynamic (Django stuff) and static (CSS/JS) Horizon content in 2 different ways: * https://github.com/openstack-dev/devstack/blob/stable/liberty/files/apache-horizon.template#L2 - dynamic content is served through Apache mod_wsgi where Apache process needs to have an access just to django.wsgi script * https://github.com/openstack-dev/devstack/blob/stable/liberty/files/apache-horizon.template#L12 - static content is served through Alias directive, which ties Web location to FileSystem location, but the FileSystem location also needs to be made explicitly available to Apache (see [2]) Then, how the Apache would be able to serve something static outside of %HORIZON_DIR% (which resides usually in /usr/share/openstack_dashboard), like our XStatic / libjs stuff? In fact it wouldn't :) - and that's what we had seen on your lab with COMPRESS_ENABLED = False. But when COMPRESS_ENABLED = True, what it does is putting compressed static assets into STATIC_ROOT [3] which is already inside %HORIZON_DIR% - the same thing that collectstatic does! So the bottom line here: in order to serve static assets from Apache you _have_ to put them to place with explicitly enabled read access. This single (and the least confusing) place is Horizon STATIC_ROOT. Either collectstatic, or compress commands of manage.py do this thing. If you don't want to multiply number of files, collectstatic --link is the only viable option. Otherwise, we won't be able to debug uncompressed statics on production environments. ** Changed in: horizon Status: New => Invalid -- You received this bug notification because you are a member of Yahoo!

Then the result isn't nice at all. Setting COMPRESS_ENABLED = False and restarting Apache leads to every xstatic library being NOT FOUND, and loading of pages taking forever.
