Subject: [RFC PATCH v2 1/3] trace2: Add a JSON schema for trace2 events
Date: Tue,  9 Jul 2019 16:05:43 -0700	[thread overview]
Message-ID: <a949db776c77e5c97c78055f1bb0f2101096f861.1562712943.git.steadmon@google.com> (raw)
In-Reply-To: <cover.1562712943.git.steadmon@google.com>

Define a JSON schema[1] that can be used to validate trace2 event
objects. This can be used to add regression tests to verify that the
event output format does not change unexpectedly.

Two versions of the schema are provided:
* event_schema.json is more permissive. It verifies that all expected
  fields are present in each trace event, but it allows traces to have
  unexpected additional fields. This allows the schema to be specified
  more concisely by factoring out the common fields into a reusable
  sub-schema.
* strict_schema.json is more restrictive. It verifies that all expected
  fields are present and no unexpected fields are present in each trace
  event. Due to this additional restriction, the common fields cannot be
  factored out into a re-usable subschema (at least as-of draft-07) [2],
  and must be repeated for each event definition.

+* list_schema.json is like event_schema.json above, but validates a JSON
+  array of trace events, rather than a single event.
+* strict_list_schema.json is like strict_schema.json above, but
+  validates a JSON array of trace events, rather than a single event.
