encoding/json/jsontext: preserve buffer capacity in Encoder.Reset

2025-07-25T17:47:45Z

This does the equivalent of CL 681177 for the Encoder. It preserves the internal buffer between resets.

encoding/json/jsontext: use bytes.Buffer.AvailableBuffer

2025-06-30T23:52:53Z

This logic was added in October, 2021: https://github.com/go-json-experiment/json/commit/0b3bd4e1ed96587be346b7f964d6bb3fcfed65f4 before the introduction of bytes.Buffer.AvailableBuffer in March, 2023. https://go.dev/cl/474635 Updates #71845 Change-Id: I96800e1ba8fce15cc78316779db4ddcd4fe1d510 Reviewed-on: https://go-review.googlesource.com/c/go/+/685136 Reviewed-by: Damien Neil Auto-Submit: Joseph Tsai LUCI-TryBot-Result: Go LUCI Reviewed-by: Dmitri Shuralyov

encoding/json/jsontext: remove Encoder.UnusedBuffer

2025-06-25T20:56:42Z

WARNING: This commit contains a breaking change. This is permissible since jsontext is experimental and not subject to the Go 1 compatibility agreement. Existing callers of UnusedBuffer should use AvailableBuffer instead.

encoding/json/jsontext: rename Encoder.UnusedBuffer as Encoder.AvailableBuffer

2025-06-25T20:56:35Z

This follows the precedent set by: bufio.Writer.AvailableBuffer bytes.Buffer.AvailableBuffer both with methods that return a zero-length buffer that is intended to only be used with a following Write call. This keeps the older UnusedBuffer method around so that at least one commit that has both methods for migration purposes.

encoding/json/jsontext: consistently use JSON terminology

2025-06-23T22:35:18Z

RFC 8259, section 2 uses the term "begin-array" amd "begin-object" rather than "start array" or "start object". Be consistent in our documentation.

encoding/json: add json/v2 with GOEXPERIMENT=jsonv2 guard

2025-04-18T15:24:07Z

This imports the proposed new v2 JSON API implemented in github.com/go-json-experiment/json as of commit d3c622f1b874954c355e60c8e6b6baa5f60d2fed. When GOEXPERIMENT=jsonv2 is set, the encoding/json/v2 and encoding/jsontext packages are visible, the encoding/json package is implemented in terms of encoding/json/v2, and the encoding/json package include various additional APIs. (See #71497 for details.) When GOEXPERIMENT=jsonv2 is not set, the new API is not present and the encoding/json package is unchanged. The experimental API is not bound by the Go compatibility promise and is expected to evolve as updates are made to the json/v2 proposal. The contents of encoding/json/internal/jsontest/testdata are compressed with zstd v1.5.7 with the -19 option.
