Overview

  1. Base#static! (upstream base.rb:1147)

Upstream: URI_INSTANCE.unescape — URI_INSTANCE is defined in upstream as URI::RFC2396_PARSER (populated in opal_patches.rb with a CGI-backed stand-in), so this works today. The homura port also dropped the ‘static_headers` setting (not used on Workers — static files are served from R2 or a CDN, not from per-request Ruby response headers). Keeping parity here.

.force_encoding(data, encoding = default_encoding) ⇒ Object

  1. Base.force_encoding (upstream base.rb:1942)

Upstream calls ‘.force_encoding(encoding).encode!`. Opal’s String#encode! raises NotImplementedError (JS Strings are immutable UTF-16). force_encoding alone is a no-op that returns the same String object. Drop encode! and guard raw JS null/undefined values before sending Ruby messages.

.setup_default_middleware(builder) ⇒ Object

  1. Base.setup_default_middleware (upstream base.rb:1846)

Upstream invokes ‘setup_host_authorization` which uses IPAddr. homura does not use host_authorization on Workers (the request host is always whitelisted by the Worker binding itself; permitted_hosts is moot). Skip that middleware.

  # NOTE: upstream calls `setup_host_authorization builder` here.
  # On Cloudflare Workers the host whitelist is enforced by the
  # wrangler.toml binding configuration itself, and the
  # `Rack::Protection::HostAuthorization` middleware is not vendored
  # (would require IPAddr, also stubbed in homura). Skipping it
  # is functionally equivalent in our deployment model.
