opcensus

Overview ¶

Command opcensus counts each service's List/Describe/Get operations for gopherstack-6flj (see services/_WRAPPER_KEY_SWEEP_REMAINDER.md).

The notes on 6flj recorded per-service remainders that turned out wrong twice, each time by a large factor (ec2 "~144" vs. the real ~220+; rds "130+ remaining" vs. the real 26), both times because the wrong number was carried forward instead of being read from the service's own operation list. This tool reads that list directly: for each services/<dir>, it parses every non-test .go file, locates the GetSupportedOperations method (every service implements it; it is the dispatcher's own declared operation set, not a doc comment or a guess), and collects the string literals it returns -- following same-package function calls it makes (ec2 delegates through two helper functions; omics delegates through a dispatch-table constructor) and, where the method instead ranges over a struct field populated elsewhere (a "h.ops" map built in a constructor), falling back to a whole-package scan for string-keyed map literals and index assignments on that field name.

This counts what each service's own dispatcher claims to support, then buckets by List/Describe/Get prefix -- a proxy for "collection or nested-shape response surface," the shape of bug this issue tracks. It says nothing about whether any individual op is correct; that is still a per-op hand read against the pinned SDK deserializer.

Usage:

go run ./cmd/opcensus                # ranked summary to stdout
go run ./cmd/opcensus -json out.json # full per-service detail
