📝 Walkthrough

Walkthrough

This PR upgrades AWS SDK for Go v2 from v1.41.12 to v1.42.0 and implements a new, environment-gated "2026" retry mode. The mode adds throttle-aware backoff computation, improves long-polling operation handling, adjusts retry token costs based on error classification, and introduces context-based long-polling tracking across all affected modules.

Changes

2026 Retry Mode Implementation

Layer / File(s)	Summary
Long-polling context infrastructure vendor/github.com/aws/aws-sdk-go-v2/internal/context/context.go, vendor/github.com/aws/aws-sdk-go-v2/aws/retry/retry.go	SetIsLongPolling and GetIsLongPolling helpers track long-polling state in request context; AddWithLongPolling wraps an existing retryer to expose IsLongPolling() bool.
Backoff computation for 2026 mode vendor/github.com/aws/aws-sdk-go-v2/aws/retry/jitter_backoff.go	ExponentialJitterBackoff gains baseDelay, throttle, and retries2026 fields; new backoffDelay2026 method forces 1s base delay on throttle errors, applies exponential growth with MAX_BACKOFF cap before jitter, while legacy mode is preserved.
Standard retry configuration and mode selection vendor/github.com/aws/aws-sdk-go-v2/aws/retry/standard.go	AWS_NEW_RETRIES_2026 environment variable gates mode detection; StandardOptions adds throttling strategies, ThrottlingRetryCost, and BaseDelay fields; NewStandard selects throttle-aware backoff in new mode; GetRetryToken uses throttling-based costs in new mode versus timeout-based costs in legacy mode; helper functions newRetries2026() and standardDefaults() supply mode-specific defaults.
Middleware retry flow adjustments vendor/github.com/aws/aws-sdk-go-v2/aws/retry/middleware.go	Token release is conditional on mode and attempt number; long-polling failure handling computes delay, adjusts via X-Amz-Retry-After header, and sleeps with context awareness; retry delay computation uses different attempt indices (attemptNum-1 in new mode); new adjustForRetryAfterHeader helper parses and clamps delay.

Dependency Updates and Metadata

Layer / File(s)	Summary
Go module dependency versions go.mod, vendor/modules.txt	github.com/aws/aws-sdk-go-v2 bumped to v1.42.0; internal modules (configsources, endpoints/v2, v4a, checksum, presigned-url, s3shared) updated to corresponding patch versions.
Generated module metadata constants vendor/github.com/aws/aws-sdk-go-v2/aws/go_module_metadata.go, vendor/github.com/aws/aws-sdk-go-v2/internal/*/go_module_metadata.go, vendor/github.com/aws/aws-sdk-go-v2/service/*/go_module_metadata.go	Module version constants updated across all affected packages (aws 1.42.0, configsources 1.4.29, endpoints/v2 2.7.29, v4a 1.4.30, checksum 1.9.22, presigned-url 1.13.29, s3shared 1.19.29, s3 1.103.3).
Changelog entries for dependency updates vendor/github.com/aws/aws-sdk-go-v2/*/CHANGELOG.md	New version sections (dated 2026-06-08) added to changelogs across all affected modules documenting dependency updates to latest SDK versions.

Poem

🐰 The retry hare hops with newfound grace,
Throttling delays in their proper place,
Long-polling now knows where it stands,
With 2026 mode in capable hands,
Dependencies fresh, the SDK expands!
