Not sure if this is a bug report or a feature request, but after upgrading to Ubuntu 24.04 and ejabberd 23.10 I tried to use a unix socket with ejabberd_http because it is behind nginx and there is no point in using TCP:

listen:
  -
    port: "unix://run/ejabberd/ejabberd_http.socket"
    unix_socket:
      mode: "0660"
    module: ejabberd_http
    tls: false  # handled by nginx
    request_handlers:
      /bosh: mod_bosh
      /captcha: ejabberd_captcha
      /upload: mod_http_upload
      /ws: ejabberd_http_ws
      /admin: ejabberd_web_admin

Unfortunately, this doesn't work:

[error] CRASH REPORT:

I see two get_auto_url functions in the ejabberd code, both require Port to be an integer:

• ejabberd/src/ejabberd_captcha.erl

  Line 516 in a19ab9f

  (integer_to_binary(Port))/binary,

• ejabberd/src/mod_host_meta.erl

  Line 161 in a19ab9f

  (integer_to_binary(Port))/binary,

Is it technically possible to refactor get_auto_url so that I manually set the base url so that it no longer tries to interpret Port as an integer?

I already did this for captcha and http upload, but it would be nice to configure the whole ejabberd_http module.

modules:
  mod_http_upload:
    put_url: "https://xmpp.andreymal.org/upload"
    get_url: "https://xmpp.andreymal.org/files"

captcha_url: "https://xmpp.andreymal.org/captcha"
