The buglog was one 27K-line JSON file whose fields covered only symptom,
root cause and fix, as free text: 2% of entries named the code version a
bug was found on, 12% the build profile, 36% a way to reproduce, and 58% of
the file was OpenWolf hook auto-detections ("Missing guard clause",
"Function not marked async" on .md files).
- .claude/skills/buglog/bug-record.md: the record standard. Eight
sections (Summary as the title, Description, Environment, Reproduction;
Root cause, Fix, Verification, References once fixed), each with the
content it must contain -- e.g. Environment needs the OS, the libc the
failing binary loads (from its ELF interpreter: glibc 2.42 in the nix
shell vs 2.40 on the host), toolchain, build profile and commit.
- .wolf/bugs/<id>.md: 500 records migrated from buglog.json; every field
verified to round-trip. They carry legacy: true and an explicit "not
recorded" where the old log had no such field; component derived from
file paths, severity from keywords (else unknown), fix_commits from
hashes in status_note/fix that git resolves (91 of 463 fixed).
- .wolf/buglog-archive.json: the 710 hook auto-detections, verbatim.
- .wolf/buglog.json is now an index generated from the records, keeping
the fields OpenWolf's hooks and `openwolf bug search` read.
- scripts/buglog.py rewritten: new (template + Environment collected from
the machine and --binary), check, status (refuses a status the record
doesn't support; fixed needs Root cause, Fix, Verification and
--commit hashes git resolves), note, recur, set, show, list, triage,
env, index. 29 unittest cases in scripts/tests/test_buglog.py.
- scripts/git-hooks/pre-commit runs `check --staged`: incomplete staged
records, a legacy record hand-changed to fixed without the fix-time
sections, a new record claiming legacy: true, or a stale index refuse
the commit.
- scripts/gitea-sync.py reads the records: issue body = the record's
sections plus linked fix commits (origin remote, GITEA_COMMIT_REPO to
override), and a body hash so an issue's text is refreshed when the
record changes.
- bug-1866 rewritten to the full standard as the worked example.

# bug-466: Unconditional 500ms config barrier wait in push_config_to_standbys reachable from iomgr epoll…
|
|
|
|
## Description
|
|
Unconditional 500ms config barrier wait in push_config_to_standbys reachable from iomgr epoll thread (ha.c raft_cb_become_leader, ha_dispatch_repl_action_for_standby, legacy election path; join.c controller join) -> blocks all controller I/O; the awaited ACK arrives on the blocked thread (structural deadlock)
|
|
|
|
## Environment
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Reproduction
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Root cause
|
|
task 5.2 made the barrier unconditional inside push_config_to_standbys while best-effort catch-up/election pushes on iomgr-reachable paths still called the same entry
|
|
|
|
## Fix
|
|
Split the API: exported transport-only fan-out push_config_transport_only (no barrier, iomgr-safe) and switched all 5 ha.c sites + join.c:187 to it; push_config_to_standbys (transport+barrier) kept for the vtask-context upgrade path only; doc comments updated in config_repl.h
|
|
|
|
## Verification
|
|
_Not recorded (migrated from buglog.json)._
