If a hook function neither calls the callback nor returns a
(non-undefined) value then there's no way for the hook system to know
if/when the hook function has finished.
The hostname:port of URIs used in Minify are currently bogus and refer
to localhost only for historical reasons; there's no reason to retain
them and omitting them avoids generating an invalid URI when "port" is
not an integer.
Context: settings.port is passed to express's listen; if not numeric, it
is used a filename for a Unix domain socket.
This allows e.g. starting a server to be reverse-proxied on a multi-user
system, using the filesystem to handle access control and avoiding need
to allocate port numbers.
Before this change, etherpad-lite starts without error when configured
to listen on a Unix domain socket in this manner. However, `pad.js` and
`ace2_common.js` are generated incorrecting, causing an error
"Uncaught Error: The module at "ep_etherpad-lite/static/js/rjquery" does not exist."
when loading the editor:
When settings.port is a non-numeric string, e.g. `etherpad.sock`, a URI
of the form `http://localhost:etherpad.sock/static/js/rjquery.js` is
generated and parsed to find the file needed. In this case, the file
searched for is `:etherpad.sock/static/js/rjquery.js`, rather than the
expected `static/js/rjquery.js`. No such file exists, and the required
code is silently omitted from the bundle.
As a workaround, hard-code a (meaningless) hostname which can be parsed
correctly, since the current code makes no use of it anyway.
`localhost`, `0.0.0.0`, `127.0.0.1` each works only in some places some of the time, this works around the problem by overriding Yajsml's built-in request mechanism in favor of a hacked together one. TODO: Serve files from another service, or directly from the file system in order to make this unnecessary.
Fixes#747
