Exception: Reeve::AuditWriteError

Inherits:

Defined in:
lib/reeve/errors.rb

Overview

Raised when the ledger write fails and audit_failure_mode is :fail (FR-012).

It carries a rule like any other denial, because the failure is not recorded anywhere else: the ledger is the thing that failed, so there is no row to read afterwards. The exception is the only artifact, and a host matching on rules can match on this one.

Instance Attribute Details

#during ⇒ Object (readonly)

during is whatever the invocation was already raising when the ledger write failed — usually a DeniedError, sometimes the tool's own exception. It is carried rather than discarded: the audit failure must win, because a call that cannot be recorded is a failed call, but the developer still needs to see what the call was doing at the time.
