Bug Report: [error-handling] — Silent error in EventBusBridge._on_domain_event

Severity Assessment

  • Impact: Events may be silently dropped if the event queue is closed, which can hide bugs and make debugging difficult.
  • Likelihood: High, as this is the designed behavior.
  • Priority: Medium

Location

  • File: src/cleveragents/a2a/events.py
  • Function/Class: EventBusBridge._on_domain_event
  • Lines: 288-289

Description

The with contextlib.suppress(RuntimeError): in EventBusBridge._on_domain_event will silently drop events if the event queue is closed. This might be the desired behavior in some cases, but it can also hide bugs and make it difficult to debug issues where events are not being processed as expected.

Evidence

        import contextlib

        with contextlib.suppress(RuntimeError):
            self._event_queue.publish(a2a_event)

Expected Behavior

The code should log a warning or an error when an event is dropped because the event queue is closed. This would provide visibility into the fact that events are being dropped and help with debugging.

Actual Behavior

The code silently drops events if the event queue is closed, which can hide bugs and make debugging difficult.

Suggested Fix

Remove the with contextlib.suppress(RuntimeError): and instead use a try...except RuntimeError: block to catch the exception and log a warning or an error message.

TDD Note

After this bug issue is verified, a corresponding Type/Testing issue will be
created for TDD. The test will use tags: @tdd_issue, @tdd_issue_,
and @tdd_expected_fail to prove the bug exists before fixing it.

auto/needs-reevaluation
Controller deferred this PR; awaiting Phase 6+ scope-evaluator or operator re-enablement.
 controller-managed
Auto-agents controller manages this PR/issue (see tools/controller/deploy/RUNBOOK.md). Remove this label to abandon controller management.
 overdue
auto/blocked-by-deps
PR blocked by an open issue dependency. Operator must close the dep (or remove the dependency link) before the merge driver can act. Auto-cleared by merge_drive when no open deps remain.
 auto/ci-timeout
Most recent merge cycle hit CI timeout. Driver excludes this PR while last merge_cycle row is < 30 min old; label persists thereafter as visible history.
 auto/claimed-implementer
Currently being processed by an implementer worker.
 auto/claimed-merge
Currently being processed by the merge driver.
 auto/claimed-reviewer
Currently being processed by a reviewer worker.
 auto/driver-down
Merge driver heartbeat stale; pipeline halted. Closed automatically on next clean tick.
 auto/invariant-violation
Detected master commit violating the strict merge invariant. Tracked as an issue (not a PR label); kept here for label completeness.
 auto/last-attempt-tier-0
In-cycle escalation: most recent attempt ran at the Tier 0 slot (`tier-0`). Slot's model defined in .opencode/models/tiers.yaml.
 auto/last-attempt-tier-1
In-cycle escalation: most recent attempt ran at the Tier 1 slot (`tier-1`). Slot's model defined in .opencode/models/tiers.yaml.
 auto/last-attempt-tier-2
In-cycle escalation: most recent attempt ran at the Tier 2 slot (`tier-2`). Slot's model defined in .opencode/models/tiers.yaml. Gated behind IMPLEMENTER_ESCALATION_TIER2_ENABLED.
 auto/last-attempt-tier-min
In-cycle escalation: most recent attempt ran at the Tier -1 slot (`tier-min`). Slot's model defined in .opencode/models/tiers.yaml. Suffix is ``-min`` (not ``--1``) so the Forgejo UI reads naturally.
 Automation Tracking

 auto/needs-conflict-resolution
Rebase conflict needs LLM conflict-resolver.
 auto/needs-implementer
Failing CI needs implementer attention.
 auto/postmortem
Documenting a driver incident or rollback.
 auto/ready-to-merge
Reviewer has APPROVED this PR and no later REQUEST_CHANGES is outstanding. The merge driver requires this label to even consider a PR for merging. Set by the reviewer worker on APPROVE; cleared on REQUEST_CHANGES.
 auto/restart-throttled
Train repeatedly lost master-tempo races. Driver excludes via merge_cycle until cooldown elapses; label persists as visible history.
 auto/revert
Revert PR backing out an invariant violation. Fast-tracked through the merge driver.
 auto/sentinel
Sentinel PR duplicated from upstream into a personal fork by tools/duplicate_prs_to_fork.py for pipeline testing. Lives only in the fork; the canonical pipeline never sees it.
 auto/stale-inactivity
No implementer activity for N days. Flagged for human review. Auto-cleared on next push to head branch.
 auto/unstable
Repeatedly fails on current master (>= 3 ci-fail-on-rebased-sha releases in 12 h). Excluded from driver until human triage.
 Blocked
A ticket in a blocked state and unable to complete until some other task is completed first.
