.baseline_configured? ⇒ Boolean

Returns:

  • (Boolean)

# File 'lib/standard_audit.rb', line 153

def baseline_configured?
  !@baseline_configuration.nil?
end

.batch ⇒ Object

Buffers record calls and flushes them via insert_all! on block exit. If the block raises, buffered records are dropped — only successful batches are persisted. Nested batches flush independently. Block-form record calls (with AS::Notifications) bypass the buffer and are processed normally since they don't persist records directly. Note: uses Thread.current for storage, which is not fiber-safe. Apps using async adapters (Falcon) should avoid concurrent batches.

end

.clear_baseline_configuration! ⇒ Object

Forgets the configure(baseline: true) block. Mainly for the gem's own specs and for a host that needs a genuinely pristine configuration.

def config

end

.configure(baseline: false, &block) ⇒ Object

Applies configuration to the single mutable Configuration instance.

baseline: true also remembers the block, so reset_configuration! replays it. That matters because the config object holds behaviour, not just data — before_checksum_hooks in particular. Without a baseline, a suite that installs the rspec plugin (which calls reset_configuration! before every example) silently loses write-time hooks after the first example, and the specs that would notice pass vacuously.

Idiomatic host usage, in config/initializers/standard_audit.rb:

StandardAudit.configure(baseline: true) do |config|
config.subscribe_to "myapp.**"
config.before_checksum :backfill_scope
end

Only the most recent baseline: true block is remembered; call it once, from the initializer.

.reset_configuration!(replay_baseline: true) ⇒ Object

Drops the memoized Configuration. Any block registered with configure(baseline: true) is replayed onto the fresh instance, so a per-example reset restores the app's real configuration rather than the gem defaults.
