What

  • Bound request-scoped HAR collectors with configurable entry details.
  • Preserve accurate body sizes and normalize HTTP status text.
  • Preserve logger-specific JSON output for derived loggers.
  • Update Go module metadata and lock files.

Why

  • Keep HAR collection bounded while retaining complete long-lived exports.
  • Maintain consistent JSON behavior across derived loggers.

Summary by CodeRabbit

  • New Features

    • Added configurable limits for retained HAR entries, dropped-entry reporting, and entry forwarding.
    • Added selective HAR detail views for headers, query parameters, and request or response bodies.
    • Added HTTP connection timeout configuration.
    • Added logger format detection for JSON output.
  • Improvements

    • Improved bounded body capture while preserving unread streaming data.
    • HAR responses now display standard HTTP reason phrases.
    • Improved safe formatting of logged messages.
    • Updated the Go toolchain and supporting libraries for compatibility and security.

Review Change Stack

Walkthrough

The PR updates Go dependencies and adds bounded HAR retention, replayable body capture, configurable HAR details, HTTP connection timeouts, safe context logging, and JSON logger state preservation.

Changes

HAR capture updates

Layer / File(s) Summary
Bounded HAR entry retention
har/har.go, har/collector.go, har/collector_test.go
Collectors limit retained entries, count dropped entries, and forward all added entries to an optional handler.
Bounded replayable body capture
har/middleware.go, har/middleware_bounded_test.go, har/middleware_test.go
Body capture uses known content lengths, limits reads, reports total size, and restores unread stream data.
HAR status and detail rendering
har/metadata.go, har/middleware.go, har/pretty.go, har/pretty_test.go, har/middleware_test.go
Responses use standard HTTP reason phrases. Entry.Detail selectively renders HAR sections.

HTTP connection timeout

Layer / File(s) Summary
Transport connection timeout
http/client.go, http/connect.go, http/connect_test.go
Client.ConnectTimeout validates the timeout, clones the transport, applies dial deadlines, and preserves existing settings.

Logger behavior updates

Layer / File(s) Summary
JSON logger capability and propagation
logger/log.go, logger/slog.go, logger/slog_test.go
Loggers expose JSON capability. SlogLogger preserves JSON mode across derived loggers and uses instance state for raw output.
Safe context logging calls
context/context.go
Context logging methods pass format strings and arguments safely to the logger.

Go dependency updates

Layer / File(s) Summary
Toolchain and module refresh
go.mod, .github/workflows/test.yml
The Go version, test matrix, and direct and indirect dependencies are updated.

Merge Risk: 🟡 Moderate · up to 3fb8a

The PR adds bounded HAR collection and preserves logger output, but its custom HTTPS dialing path can bypass the configured connection timeout, allowing requests to hang; the current head is not merge-ready until the timeout wrapping and regression coverage are fixed.

Cover constructor output, not only the JSON flag.

newLogger sets json directly and installs a TextHandler even when json is true. This test can pass if New or NewWithWriter fails to set JSON mode, and it does not verify handleRaw output. Construct the production loggers and assert that emitted records are valid JSON. Keep the derived-logger propagation checks.

In `@har/middleware.go`:
- Around line 133-151: The sentinel limit in the body-capture flow must not
overflow when maxSize is math.MaxInt64. Update the read-limit calculation before
io.LimitReader so the maximum int64 value is treated as uncapped or otherwise
avoids adding one; preserve truncation and totalSize behavior for finite limits,
and add a regression test covering the maximum configuration.

In `@http/connect.go`:
- Around line 26-35: Prevent ConnectTimeout wrappers from nesting by storing the
original dial function separately on Client, such as a connectDialContext field,
and have each ConnectTimeout call wrap that original function rather than the
previously configured wrapper. Preserve builder compatibility and add a
regression test verifying that a later timeout replaces an earlier timeout.

Wrap custom TLS dialing in ConnectTimeout.

When DialTLSContext is set, net/http.Transport uses it for non-proxied HTTPS requests and skips DialContext. Cache and wrap the original DialTLSContext, then add a blocking HTTPS regression test.

132-137: 📐 Maintainability & Code Quality | 🟡 Minor | ⚡ Quick win

Validate emitted JSON for derived loggers.

IsJSONLogger only checks the JSON capability state in logger/log.go, Lines 86-89. These assertions can pass even if WithValues or WithV preserves the flag but emits through a non-JSON path. Emit one record through each derived logger and validate it with assertRecord.

Bound request-scoped collectors while forwarding complete entries to long-lived HAR exports.
Preserve accurate body sizes without reading entire payloads, normalize HTTP status text, and expose configurable entry detail sections.
Use the concrete logger's output mode instead of global configuration, preserving JSON behavior across derived loggers.
Use safe logging formats, preserve dialer behavior across repeated connection-timeout configuration, and prevent maximum body limits from overflowing. Expand regression coverage and update CI to Go 1.26.
