Overview

Command: Find an existing error by hash or create a new one Uses pessimistic locking to prevent race conditions in multi-app scenarios.

Search order:

  1. Unresolved errors with same hash within 24 hours → increment occurrence count
  2. Resolved/wont_fix errors with same hash (any age) → reopen and increment
  3. No match → create new error record

Environment is a MATCH dimension, not part of the hash: the same error in staging and production is two rows with independent status. A row with a NULL environment predates the column; it matches as a wildcard and is stamped by the first occurrence that claims it, so history migrates itself without a backfill. An exact match always wins over a NULL one.

Constant Summary collapse

REFRESHED_CONTEXT =

Context that describes THIS occurrence rather than the error as a group. It is refreshed on every recurrence so the row always shows the latest moment of failure, not the first one in the 24 h window. Keys absent from @attributes (feature disabled, column not migrated, or a storm :lite capture that shed context) leave the stored payload alone — a shed capture must never blank out a good snapshot.
