Module: StillActive::CompactIndexClient

Extended by:
CompactIndexClient
Included in:
CompactIndexClient
Defined in:
lib/still_active/compact_index_client.rb

Overview

The RubyGems compact index (/info/<gem>), which is what Bundler itself resolves through. It is not built by merging upstream metadata, so it lists the versions actually resolvable from the source even when a member remote (a legacy private gem host) can't answer the metadata endpoint Artifactory prefers (#142).

The protocol is generic: any host that serves it (rubygems.org, Artifactory, a direct Contribsys/Gemstash/geminabox source) works here. The caller supplies the source URI and any auth headers, so this stays free of host-specific credential handling.

  # The parser never raises: a non-index 200 (an auth wall or HTML error page
  # served with status 200) yields no versions instead of an error. Since the
  # compact index is the primary source, a silent empty result would look
  # identical to a clean parse and hide a broken source, so say so and let the
  # caller fall through. A header-only index (every version yanked) is valid
  # and empty, so the "---" marker, not mere emptiness, tells them apart.
