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-1785: Found immediately after fixing bug-1784: with named-usergroup resolution working, a limit scoped…
|
|
|
|
## Description
|
|
Found immediately after fixing bug-1784: with named-usergroup resolution working, a limit scoped to only SOME of the four dimensions (users.yaml's demo limits.yaml sets users+queues on ug1_normal_slots but never projects/hosts) still matched no one at all.
|
|
|
|
## Environment
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Reproduction
|
|
_Not recorded (migrated from buglog.json)._
|
|
|
|
## Root cause
|
|
build_consumer() (xcelimit.c) is documented to default an unconfigured scope to the builtin "all" group (matching everyone) when g_config is NULL. But capnp encodes LimitConfig's users/queues/projects/hosts as embedded GROUPS, not nullable pointers (xceadmin's mapping.py: _build_membership_group() no-ops on an absent YAML key, but the embedded capnp struct is still present on the wire as an empty-but-non-NULL group) -- so an unconfigured scope arrives here as a non-NULL xce_group_config_t with zero members/ex_members, never as NULL. build_consumer()'s g_config!=NULL branch then builds a real, empty, UNNAMED group via makeGroup() -- a group that (per is_in_group()'s own logic) matches no one, the exact OPPOSITE of the intended "unrestricted" default. Every limit in this repo's demo limits.yaml configures only a subset of the four scopes, so every one of them was silently rejecting every job on its unconfigured dimensions.
|
|
|
|
## Fix
|
|
FIXED (2026-09-07). build_consumer() now normalizes an empty-but-present g_config (members.count==0 AND ex_members.count==0) to NULL before the existing g_config!=NULL/NULL branch runs, restoring the documented "fall back to all" behavior for a genuinely-unconfigured scope. An operator who wants "no one" for a scope still has the builtin "empty" group to reference by name explicitly, so this doesn't remove any real capability. TDD: new test_build_consumer_empty_config_defaults_to_all (src/lib/testsuite/test_limit.c) -- builds a zero-valued xce_group_config_t{0}, asserts build_consumer() falls back to a group where is_in_group() matches an arbitrary name. Passes (313 lib tests, 0 failures). Full scheduler suite: 76/77 (pre-existing bug-1762). LIVE-VERIFIED as part of the same trace as bug-1784/1786/1787/1788 -- combined, these let match_limit() and instantiate_limit() run to completion for all 7 limits in limits.yaml on every job submission (previously it silently rejected on the FIRST unconfigured scope it hit).
