From e54ee755135be1fe0ddc9d1634204149eb5dc5a0 Mon Sep 17 00:00:00 2001 From: Graham McIntire Date: Sat, 21 Mar 2026 16:08:40 -0500 Subject: [PATCH] Rewrite protobuf encoding/decoding in pure Gleam with integrated validation (#104) Replace the protobuf hex package (agent.pb.ex) and hand-written validator (validator.ex) with a pure Gleam implementation: wire format primitives, all 23 message types, encode/decode functions, and validation merged into decode. Thin Elixir wrappers in agent.ex preserve the existing struct API. - Wire format: varint, length-delimited, double (IEEE 754 via FFI), tag encode/decode - Types: all proto3 message types as Gleam custom types with enums and oneof - Decode: field-level parsing with integrated validation (UUID, IP, hostname, limits) - Encode: proto3 default omission, bytes_tree concatenation, map/repeated fields - Wrappers: Elixir structs with encode/decode delegating to Gleam, enum atom conversion - Remove {:protobuf, "~> 0.12"} dependency Reviewed-on: https://git.mcintire.me/graham/towerops-web/pulls/104 --- .forgejo/workflows/pr-tests.yaml | 9 + gleam.toml | 1 + gleam_lint.toml | 24 + lib/towerops/agent/validator.ex | 659 ----- lib/towerops/proto/agent.ex | 1035 ++++++++ lib/towerops/proto/agent.pb.ex | 628 ----- lib/towerops_web/channels/agent_channel.ex | 22 +- manifest.toml | 11 + mix.exs | 9 +- mix.lock | 1 - src/towerops/proto/decode.gleam | 2352 +++++++++++++++++ src/towerops/proto/encode.gleam | 416 +++ src/towerops/proto/types.gleam | 392 +++ src/towerops/proto/wire.gleam | 335 +++ src/towerops_proto_decode_ffi.erl | 79 + src/towerops_proto_wire_ffi.erl | 54 + test/towerops/agent/validator_test.exs | 291 +- test/towerops/proto/agent_pb_test.exs | 82 +- test/towerops/proto/agent_test.exs | 273 +- test/towerops/proto/wire_test.exs | 214 ++ .../agent_channel_check_proto_test.exs | 87 +- .../channels/agent_channel_test.exs | 26 +- 22 files changed, 5292 insertions(+), 1708 deletions(-) create mode 100644 gleam_lint.toml delete mode 100644 lib/towerops/agent/validator.ex create mode 100644 lib/towerops/proto/agent.ex delete mode 100644 lib/towerops/proto/agent.pb.ex create mode 100644 src/towerops/proto/decode.gleam create mode 100644 src/towerops/proto/encode.gleam create mode 100644 src/towerops/proto/types.gleam create mode 100644 src/towerops/proto/wire.gleam create mode 100644 src/towerops_proto_decode_ffi.erl create mode 100644 src/towerops_proto_wire_ffi.erl create mode 100644 test/towerops/proto/wire_test.exs diff --git a/.forgejo/workflows/pr-tests.yaml b/.forgejo/workflows/pr-tests.yaml index 81bbd2a0..56e0de91 100644 --- a/.forgejo/workflows/pr-tests.yaml +++ b/.forgejo/workflows/pr-tests.yaml @@ -91,6 +91,15 @@ jobs: - name: Compile (warnings as errors) run: mix compile --warnings-as-errors + - name: Lint Gleam (glinter) + run: | + output=$(gleam run -m glinter 2>&1) || true + echo "$output" + if echo "$output" | grep -qE '\([1-9][0-9]* errors?,'; then + echo "::error::Gleam lint errors found" + exit 1 + fi + - name: Run tests run: mix test diff --git a/gleam.toml b/gleam.toml index 315a0a2d..e59b2e4c 100644 --- a/gleam.toml +++ b/gleam.toml @@ -8,3 +8,4 @@ gleam_regexp = ">= 1.0.0 and < 2.0.0" [dev-dependencies] gleeunit = ">= 1.0.0 and < 2.0.0" +glinter = ">= 1.0.0 and < 2.0.0" diff --git a/gleam_lint.toml b/gleam_lint.toml new file mode 100644 index 00000000..bc372430 --- /dev/null +++ b/gleam_lint.toml @@ -0,0 +1,24 @@ +[rules] +# Errors: these should fail CI +avoid_panic = "error" +avoid_todo = "error" +echo = "error" +discarded_result = "error" +division_by_zero = "error" +error_context_lost = "error" +thrown_away_error = "error" +duplicate_import = "error" +# Warnings: kept as informational +assert_ok_pattern = "warning" +unwrap_used = "warning" +redundant_case = "warning" +unnecessary_variable = "warning" +# Off: too noisy for this codebase +label_possible = "off" +missing_labels = "off" +short_variable_name = "off" +prefer_guard_clause = "off" +module_complexity = "off" +function_complexity = "off" +deep_nesting = "off" +ffi_usage = "off" diff --git a/lib/towerops/agent/validator.ex b/lib/towerops/agent/validator.ex deleted file mode 100644 index 7d40a938..00000000 --- a/lib/towerops/agent/validator.ex +++ /dev/null @@ -1,659 +0,0 @@ -defmodule Towerops.Agent.Validator do - @moduledoc """ - Strict validation for Protocol Buffer messages from agents. - - Provides validation on top of protobuf schema to catch malformed data, - injection attempts, and business logic violations before processing. - - ## Philosophy - - Protobuf provides schema-level validation (types, required fields) but - doesn't validate business constraints.
