[dependabot]

Bumps github.com/jhonsferg/relay from 0.1.1 to 0.1.24.

Release notes

Sourced from github.com/jhonsferg/relay's releases.

v0.1.10 - WithErrorDecoder + lazy context allocation

What's changed

New feature: WithErrorDecoder

Translates HTTP error status codes into typed Go errors (OpenFeign parity).

var ErrNotFound = errors.New("not found")
client := relay.New(
relay.WithErrorDecoder(func(status int, body []byte) error {
if status == http.StatusNotFound {
return ErrNotFound
}
return nil  // nil = return response normally
}),
)

Behaviour:

• Called only when status >= 400
• Runs after all OnAfterResponse hooks
• Returns non-nil error: response is pooled, Execute returns (nil, err)
• Returns nil: response returned normally (opt-out per status code)
• Default nil decoder: no behaviour change

Refactor: lazy context allocation

Redirect counter + httptrace context deferred until after circuit breaker check. When CB rejects a request, 11 allocations are avoided. Happy path unchanged at 104 allocs/op.

Full changelog: v0.1.9...v0.1.10

v0.1.9

What's changed

Performance

• dns_cache.go: Pre-join host:port in cache entries at DNS resolution time, eliminating net.JoinHostPort from the hot dial path. Validated with benchstat (count=6, p=0.002): -10.00% allocs/op, -7.24% ns/op

Refactors

• cache.go: Lazy-init expired map in evict() - avoids an unconditional heap allocation on every eviction cycle when no entries have expired

Tests

• Added BenchmarkDNSCache_WarmDialPath to validate the DNS cache improvement
• Added hotspot micro-benchmarks for PathBuilder, cache-hit replay and stream-open paths

Phase 2b audit findings

All 19 previously untouched source files profiled via pprof + escape analysis. Only dns_cache.go had a relay-controlled optimisation exceeding the 5% threshold. All other files are either dominated by net/http internals or the compiler already eliminates the allocation.
