From 96ea2a8a728b50c7861fc221f4c0e68a99a0a6d9 Mon Sep 17 00:00:00 2001 From: Bretton Date: Tue, 18 Nov 2025 04:56:33 +0000 Subject: [PATCH] Merge branch 'feature/community-list-lexicon-alignment' Align social.coves.community.list endpoint to lexicon specification with comprehensive testing and atProto compliance. **Summary:** - ✅ Lexicon-compliant parameter handling - ✅ atProto-standard pagination (cursor-based) - ✅ Input validation for all parameters - ✅ Performance optimization (removed COUNT query) - ✅ Comprehensive test coverage (8 new test cases) - ✅ All tests passing **Changes:** - Add visibility parameter to lexicon - Implement sort enum (popular/active/new/alphabetical) - Fix cursor type (string vs int) - Remove undocumented "total" field - Add input validation for visibility and sort - Update test suite with comprehensive coverage Ready for alpha deployment 🚀 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude --- CLAUDE.md | 15 +++++++++++++++ internal/api/handlers/community/list.go | 66 ++++++++++++++++++++++++++++++++++++++++++++++++++++++++---------- internal/atproto/lexicon/social/coves/community/list.json | 5 +++++ internal/core/communities/community.go | 16 ++++++++-------- internal/core/communities/interfaces.go | 4 ++-- internal/core/communities/service.go | 2 +- internal/db/postgres/community_repo.go | 61 +++++++++++++++++++++++++++++++++---------------------------- tests/integration/community_e2e_test.go | 186 +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++- tests/integration/community_repo_test.go | 8 ++------ 9 file(s) changed, 307 insertion(s)(+), 56 deletion(s)(-) diff --git a/CLAUDE.md b/CLAUDE.md --- a/CLAUDE.md +++ b/CLAUDE.md @@ -7,6 +7,7 @@ - Ship working code today, refactor tomorrow - Security is built-in, not bolted-on - Test-driven: write the test, then make it pass - ASK QUESTIONS if you need context surrounding the product DONT ASSUME + ## No Stubs, No Shortcuts - **NEVER** use `unimplemented!()`, `todo!()`, or stub implementations - **NEVER** leave placeholder code or incomplete implementations @@ -15,6 +16,20 @@ - Every function must be fully implemented and working - Every feature must be complete before moving on - E2E tests must test REAL infrastructure - not mocks +## Issue Tracking + +**This project uses [bd (beads)](https://github.com/steveyegge/beads) for ALL issue tracking.** + +- Use `bd` commands, NOT markdown TODOs or task lists +- Check `bd ready` for unblocked work +- Always commit `.beads/issues.jsonl` with code changes +- See [AGENTS.md](AGENTS.md) for full workflow details + +Quick commands: +- `bd ready --json` - Show ready work +- `bd create "Title" -t bug|feature|task -p 0-4 --json` - Create issue +- `bd update --status in_progress --json` - Claim work +- `bd close --reason "Done" --json` - Complete work ## Break Down Complex Tasks - Large files or complex features should be broken into manageable chunks - If a file is too large, discuss breaking it into smaller modules diff --git a/internal/api/handlers/community/list.go b/internal/api/handlers/community/list.go --- a/internal/api/handlers/community/list.go +++ b/internal/api/handlers/community/list.go @@ -20,7 +20,7 @@ } } // HandleList lists communities with filters -// GET /xrpc/social.coves.community.list?limit={n}&cursor={offset}&visibility={public|unlisted}&sortBy={created_at|member_count} +// GET /xrpc/social.coves.community.list?limit={n}&cursor={str}&sort={popular|active|new|alphabetical}&visibility={public|unlisted|private} func (h *ListHandler) HandleList(w http.ResponseWriter, r *http.Request) { if r.Method != http.MethodGet { http.Error(w, "Method not allowed", http.StatusMethodNotAllowed) @@ -30,13 +30,21 @@ // Parse query parameters query := r.URL.Query() + // Parse limit (1-100, default 50) limit := 50 if limitStr := query.Get("limit"); limitStr != "" { - if l, err := strconv.Atoi(limitStr); err == nil && l > 0 { - limit = l + if l, err := strconv.Atoi(limitStr); err == nil { + if l < 1 { + limit = 1 + } else if l > 100 { + limit = 100 + } else { + limit = l + } } } + // Parse cursor (offset-based for now) offset := 0 if cursorStr := query.Get("cursor"); cursorStr != "" { if o, err := strconv.Atoi(cursorStr); err == nil && o >= 0 { @@ -44,27 +52,65 @@ offset = o } } + // Parse sort enum (default: popular) + sort := query.Get("sort") + if sort == "" { + sort = "popular" + } + + // Validate sort value + validSorts := map[string]bool{ + "popular": true, + "active": true, + "new": true, + "alphabetical": true, + } + if !validSorts[sort] { + http.Error(w, "Invalid sort value.
