Bump github.com/buger/jsonparser from 1.2.0 to 1.6.1

[dependabot]

Bumps github.com/buger/jsonparser from 1.2.0 to 1.6.1.

Release notes

Sourced from github.com/buger/jsonparser's releases.

v1.6.1 — Fastest across all payload sizes (now benchmarks vs gjson + sonic)

🔒 Covered by ReqProof — L3 Assurance (123 requirements, 0 errors, 0 warnings)

Performance — gjson-style fast-skip

Ported gjson's >'\\' single-comparison fast-skip to three hot loops. The trick skips all non-structural bytes (those > 0x5C) in one unsigned comparison per byte, reducing branch overhead.

Payload	Before	After	Change
Small (190B)	382 ns	339 ns	-11.3%
Medium (2.4kB)	3,899 ns	3,141 ns	-19.4%
Large (24kB)	20,788 ns	20,114 ns	-3.2%

Now benchmarks against gjson and sonic

Added tidwall/gjson (15.5k⭐) and bytedance/sonic (9.6k⭐) to the benchmark suite.

Large payload — the definitive ranking:

Library	time/op	allocs
jsonparser	20,114 ns	0
gjson	22,756 ns	2
easyjson	33,771 ns	134
sonic	41,053 ns	71
ffjson	59,063 ns	144
encoding/json	130,565 ns	147

jsonparser is the fastest across ALL payload sizes and the only zero-allocation parser.

Full changelog: CHANGELOG.md

v1.6.0 — Append function + zero open known issues

🔒 Covered by ReqProof — L3 Assurance (123 requirements, 0 errors, 0 warnings, 0 open known issues)

New API: Append

// Append to an array without knowing its length
data, _ = jsonparser.Append(data, []byte(`"new_item"`), "items")

Append(data, value, keys...) ([]byte, error) — clean array-append API. Works on top-level and nested arrays. Auto-creates missing paths as single-element arrays. No need for [N] path syntax.

Bug fixes — all known issues resolved

KI	Fix
KI-2	ParseInt("-") now returns MalformedValueError (was returning 0, nil)
KI-3	Disposition corrected to fixed (auto-coerce was implemented in v1.3.0)

... (truncated)

[v1.6.1] — 2026-07-29

Covered by ReqProof — L3 Assurance (123 requirements, 0 errors, 0 warnings)

Performance — gjson-style fast-skip in hot loops

Ported gjson's >'\\' fast-skip trick to three inner loops in parser.go: stringEndConfig tail, blockEndConfig, and searchKeysConfig. The trick uses a single unsigned comparison (byte > 0x5C) to skip all non-structural bytes in bulk, reducing per-byte branch overhead.

Payload	Before	After	Improvement
Small (190B)	382 ns	339 ns	-11.3%
Medium (2.4kB)	3,899 ns	3,141 ns	-19.4%
Large (24kB)	20,788 ns	20,114 ns	-3.2%

Zero allocations maintained on all paths.

Benchmarks — now includes gjson and sonic

Added tidwall/gjson (15.5k⭐, path-based parser like jsonparser) and bytedance/sonic (9.6k⭐, SIMD-accelerated deserializer) to the benchmark suite.

Final leaderboard (large payload):

Library	time/op	bytes/op	allocs/op
buger/jsonparser	20,114	0	0
tidwall/gjson	22,756	28,672	2
mailru/easyjson	33,771	4,016	134
bytedance/sonic	41,053	31,368	71
pquerna/ffjson	59,063	4,822	144
encoding/json	130,565	4,432	147

jsonparser is the fastest across all payload sizes and the only zero-allocation parser.
