From 9b16d7d3a65913f9c68787db5fcf94104d597635 Mon Sep 17 00:00:00 2001 From: Claude Date: Thu, 9 Apr 2026 19:12:47 +0000 Subject: [PATCH] =?UTF-8?q?feat:=20comprehensive=20repo=20improvements=20?= =?UTF-8?q?=E2=80=94=20error=20types,=20rate=20limiting,=20retry,=20BGP/RP?= =?UTF-8?q?KI,=20tests,=20CI?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - Complete NetworkVerifier BGP/RPKI checks via Team Cymru DNS and Cloudflare RPKI API - Implement Certificate Transparency lookup via crt.sh - Complete Zig FFI bridge: replace template placeholders, add feedback-specific ops (compute_hash, generate_id, validate_https), update version to 1.0.0 - Add structured error types (AuthenticationError, RateLimitError, NetworkError, ValidationError, PlatformError, DuplicateError) replacing generic error tuples - Add per-platform RateLimiter with token bucket algorithm and configurable limits - Add Retry module with exponential backoff, jitter, and retryable error classification - Integrate RateLimiter and Retry into Submitter - Update all channel adapters (GitHub, GitLab, Bitbucket, Codeberg, Bugzilla) to return structured errors - Add comprehensive test suite: credentials, audit_log, rate_limiter, retry, channel registry, integration tests for all channel adapters - Add Elixir CI pipeline: multi-version matrix, format check, dialyzer - Synchronize STATE.a2ml to v1.0.0 production status - Add CONTRIBUTING.adoc with language policy, dev guidelines, architecture overview https://claude.ai/code/session_01CdyQBqSt5j3WRoveJWKyip --- .github/workflows/elixir-ci.yml | 98 +++++++++ .machine_readable/6a2/STATE.a2ml | 28 ++- CONTRIBUTING.adoc | 121 +++++++++++ elixir-mcp/lib/feedback_a_tron/application.ex | 1 + .../lib/feedback_a_tron/channels/bitbucket.ex | 13 +- .../lib/feedback_a_tron/channels/bugzilla.ex | 13 +- .../lib/feedback_a_tron/channels/codeberg.ex | 13 +- .../lib/feedback_a_tron/channels/github.ex | 23 +- .../lib/feedback_a_tron/channels/gitlab.ex | 16 +- elixir-mcp/lib/feedback_a_tron/error.ex | 78 +++++++ .../lib/feedback_a_tron/network_verifier.ex | 151 +++++++++++-- .../lib/feedback_a_tron/rate_limiter.ex | 203 ++++++++++++++++++ elixir-mcp/lib/feedback_a_tron/retry.ex | 122 +++++++++++ elixir-mcp/lib/feedback_a_tron/submitter.ex | 21 +- elixir-mcp/test/audit_log_test.exs | 148 +++++++++++++ elixir-mcp/test/channel_test.exs | 72 +++++++ elixir-mcp/test/credentials_test.exs | 82 +++++++ .../integration/channel_integration_test.exs | 102 +++++++++ elixir-mcp/test/rate_limiter_test.exs | 84 ++++++++ elixir-mcp/test/retry_test.exs | 126 +++++++++++ ffi/zig/build.zig | 14 +- ffi/zig/src/main.zig | 114 ++++++++-- ffi/zig/test/integration_test.zig | 176 +++++++++++---- 23 files changed, 1700 insertions(+), 119 deletions(-) create mode 100644 .github/workflows/elixir-ci.yml create mode 100644 CONTRIBUTING.adoc create mode 100644 elixir-mcp/lib/feedback_a_tron/error.ex create mode 100644 elixir-mcp/lib/feedback_a_tron/rate_limiter.ex create mode 100644 elixir-mcp/lib/feedback_a_tron/retry.ex create mode 100644 elixir-mcp/test/audit_log_test.exs create mode 100644 elixir-mcp/test/channel_test.exs create mode 100644 elixir-mcp/test/credentials_test.exs create mode 100644 elixir-mcp/test/integration/channel_integration_test.exs create mode 100644 elixir-mcp/test/rate_limiter_test.exs create mode 100644 elixir-mcp/test/retry_test.exs diff --git a/.github/workflows/elixir-ci.yml b/.github/workflows/elixir-ci.yml new file mode 100644 index 0000000..f71539c --- /dev/null +++ b/.github/workflows/elixir-ci.yml @@ -0,0 +1,98 @@ +# SPDX-License-Identifier: PMPL-1.0-or-later +name: Elixir CI + +on: + push: + branches: [main] + paths: + -
