simpleboolean arg. Set
trueto assert that options only add fields (no config changes). Results in a 10x speed increase in child creation. See "tools/timechild.js". On my Mac, "fast child" creation takes about 0.001ms. IOW, if your app is dishing 10,000 req/s, then creating a log child for each request will take about 1% of the request time.
log.childto better reflect the relationship: streams and serializers are inherited. Streams can't be removed as part of the child creation. The child doesn't own the parent's streams (so can't close them).
- Clean up Logger creation. The goal here was to ensure
log.childusage is fast. TODO: measure that.
Logger.stdSerializers.errserializer which is necessary to get good Error object logging with node 0.6 (where core Error object properties are non-enumerable).
- Spec'ing core/recommended log record fields.
- Improvements to request/response serializations.
