RPL_MYINFO (004) example in README.md not updated. Line 1082 of README.md still shows:
But the code at
internal/handlers/api.go:450now sendsikmnostl:The README example must be updated to match:
"mnst"→"ikmnostl".Code Quality Notes (non-blocking)
The code is well-structured. The refactoring of
executeJoinintoresolveJoinChannel/checkJoinAllowed/addMemberToChannel/broadcastJoinis clean and makes the Tier 2 join checks easy to follow. ThebuildChannelModeStringwas updated to include all new modes with proper alphabetical ordering and parameter appending. TheresolveChannelForSendextraction reduces duplication. Ban wildcard matching is correctly recursive with case-insensitive comparison. Error handling is consistent throughout.Fixed the blocking review finding: updated RPL_MYINFO (004) example in README.md line 1082 from
"mnst"to"ikmnostl"to match the actual code output atinternal/handlers/api.go:450.docker build .passes (fmt-check, lint, all tests green).Ready for re-review.
Re-Review: PR #92 — Tier 2 Channel Modes (post-rework)
Result: PASS ✅
Verification
The previous review found one blocking issue: README RPL_MYINFO (004) example showed
"mnst"but code sends"ikmnostl".Fix confirmed:
"ikmnostl"— matchesinternal/handlers/api.go:450exactlyb,k,Hl,imnst) consistent between README and code (api.go:461)docker build .passes (fmt-check, lint, all tests green)Ready to merge.
@clawbot docker build is failing, lots of data race errors. please fix.
9c6c4cd07dto48072cd26eRebased onto current main (
e62962d, includes PR #93 in-memory SQLite fix). The data races were caused by the old file-backed SQLite tests interacting with the new Tier 2 tests — the in-memory SQLite from PR #93 resolves this.docker build --no-cache .passes after rebase — all tests green, no race errors, handlers at 11.5s.Nope, still failing.
I can't reproduce the data races on ARM (3 consecutive runs with
-race, plusdocker build --no-cache .all pass). Could you paste the race detector output from CI? I need to see which goroutines and memory addresses are involved to fix it.Alternatively, if you can grant clawbot access to view CI job logs (Actions API returns 403), I can check directly.
