Davanum Srinivas c40ea60b9f Update OpenTelemetry dependencies to latest versions
Core packages (opentelemetry-go):
- go.opentelemetry.io/otel: v1.38.0 → v1.39.0
- go.opentelemetry.io/otel/metric: v1.38.0 → v1.39.0
- go.opentelemetry.io/otel/trace: v1.38.0 → v1.39.0
- go.opentelemetry.io/otel/sdk: v1.38.0 → v1.39.0

Exporters:
- go.opentelemetry.io/otel/exporters/otlp/otlptrace: v1.34.0 → v1.39.0
- go.opentelemetry.io/otel/exporters/otlp/otlptrace/otlptracegrpc: v1.34.0 → v1.39.0

Contrib instrumentation (opentelemetry-go-contrib):
- go.opentelemetry.io/contrib/.../otelhttp: v0.61.0 → v0.64.0
- go.opentelemetry.io/contrib/.../otelrestful: v0.44.0 → v0.64.0

Protocol definitions (opentelemetry-proto-go):
- go.opentelemetry.io/proto/otlp: v1.5.0 → v1.9.0

Notable changes:
- Go 1.24 is now the minimum required version (Go 1.23 support dropped) for OTEL components
- Performance: ~4x improvement in histogram concurrent operations; xxhash
  replaces fnv for attribute hashing
- Fixed goroutine leak in span processors when context is canceled
- otelrestful migrated semantic conventions from v1.20.0 to v1.34.0
  (e.g., http.method → http.request.method)
- Partial OTLP export errors now surfaced instead of being silently dropped
- otelrestful no longer depends on json-iterator/go, modern-go/concurrent,
  or modern-go/reflect2; unwanted-dependencies.json updated accordingly

Exponential Backoff GoDoc

This is a Go port of the exponential backoff algorithm from Google's HTTP Client Library for Java.

Exponential backoff is an algorithm that uses feedback to multiplicatively decrease the rate of some process, in order to gradually find an acceptable rate. The retries exponentially increase and stop increasing when a certain threshold is met.

Usage

Import path is github.com/cenkalti/backoff/v5. Please note the version part at the end.

For most cases, use Retry function. See example_test.go for an example.

If you have specific needs, copy Retry function (from retry.go) into your code and modify it as needed.

Contributing

  • I would like to keep this library as small as possible.
  • Please don't send a PR without opening an issue and discussing it first.
  • If proposed change is not a common use case, I will probably not accept it.
