From 43a164ed7221af19fe63030d856095bd1bc05374 Mon Sep 17 00:00:00 2001 From: Andrew Nesbitt Date: Mon, 6 Apr 2026 12:55:15 +0100 Subject: [PATCH 1/8] Add cooldown support for Hex Decode the Hex registry protobuf format, filter releases by fetching timestamps from the Hex HTTP API (hex.pm/api/packages/{name}), and re-encode without the original signature. The protobuf handling uses protowire for low-level encoding/decoding of the Signed wrapper, Package, and Release messages. Timestamps come from the inserted_at field in the JSON API response. Since the proxy re-encodes the payload without the original signature, users need to disable registry signature verification. --- README.md | 4 +- docs/configuration.md | 4 +- go.mod | 2 +- internal/handler/hex.go | 334 ++++++++++++++++++++++++++++++++++- internal/handler/hex_test.go | 297 +++++++++++++++++++++++++++++++ 5 files changed, 637 insertions(+), 4 deletions(-) diff --git a/README.md b/README.md index 242f378..069c64f 100644 --- a/README.md +++ b/README.md @@ -30,7 +30,7 @@ Currently works with npm, PyPI, pub.dev, Composer, and Cargo, which all include | Cargo | Rust | Yes | ✓ | | RubyGems | Ruby | Yes | ✓ | | Go proxy | Go | | ✓ | -| Hex | Elixir | | ✓ | +| Hex | Elixir | Yes* | ✓ | | pub.dev | Dart | Yes | ✓ | | PyPI | Python | Yes | ✓ | | Maven | Java | | ✓ | @@ -52,6 +52,8 @@ Currently works with npm, PyPI, pub.dev, Composer, and Cargo, which all include Cooldown requires publish timestamps in metadata.
