Problem

Generated processors now dispatch only through the METHODS table (the process_<name> methods are gone). When a service extends another one, the child processor inherits from the parent processor. self.class::METHODS only returns the child's constant, so the parent's methods are never registered.

As a result, every inherited method fails with Unknown function <name>. For example, add_influencers on analytics.manager.Manager, which extends base.EntityManager.

Fix

Thrift::Processor#initialize now walks the class ancestors and merges every METHODS table it finds. A method defined in the child still takes precedence over the parent's.

Tests

• Added a spec with a processor extending another one. It calls both an inherited method and one of its own.
• Checked against the real Analytics::Thrift::Manager::Processor (analytics-thrift-v2 0.0.19, base-thrift-v2 0.1.176):
  • before: Unknown function add_influencers
  • after: normal reply

• Did you create an Apache Jira ticket? (not required for trivial changes)
• If a ticket exists: Does your pull request title follow the pattern "THRIFT-NNNN: describe my issue"?
• Did you squash your changes to a single commit? (not required, but preferred)
• Did you do your best to avoid breaking changes? If one was needed, did you label the Jira ticket with "Breaking-Change"?
• If your change does not involve any code, add [skip ci] at the end of your pull request to free up build resources.
