- adds a common/servermetrics package that owns the metrics MetricsMessage wire
format and the reporting/usage subsystem (message builder, usage registry,
interval and usage counters), wrapping the openziti/metrics Registry for
metric collection
- moves the controllers metrics reporter into the router package and removes it
from the shared metrics package, breaking a common -> router/env import cycle
- repoints controller and router consumers to common/servermetrics; base metric
collection stays on openziti/metrics
- keeps the proto field numbers and the metrics content-type identical so the
encoding is byte-compatible across the move, and uses a distinct proto package
name so ziti's and the library's messages coexist without a global proto
registry clash
- adds a round-trip test asserting wire compatibility with the library's
MetricsMessage
- leaves openziti/metrics unchanged, so sdk-golang and the shared xgress data
plane are unaffected
- moves the channel dependency to channel/v5 v5.0.10 and sdk-golang to v1.9.0 in the root and zititest modules
- mechanically rewrites every channel/v4 import path to channel/v5
This is the import-path-only step; the API-level changes the switch requires land in the following commit. This commit does not build on its own.
Previously we often had two sets of events, one in the network
package, and then another in the events package. We now only
have one, in the events package. Events now have a public API,
with minimal deps. There's an implementation package which has
the dependencies. This allows the network package to generate
events, without have a circular dependency on the events
implementation package.
