build(deps): bump github.com/buger/jsonparser from 1.2.0 to 1.6.0

[dependabot]

Bumps github.com/buger/jsonparser from 1.2.0 to 1.6.0.

Release notes

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

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)
KI-4	Set([1,2,3], val, "[5]") now appends instead of returning KeyPathNotFoundError

Zero open known issues. All 4 KIs are now status: fixed.

Full changelog: CHANGELOG.md

v1.5.0 — Config (lenient parsing), streaming ReaderParser, name aliases

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

Config struct — opt-in lenient parsing (#160, #115)

var Lenient = jsonparser.Config{AllowSingleQuotes: true, AllowUnknownEscapes: true}
Lenient.Get(data, "key")  // parses {'key':'value'} and unknown escapes

Single-quote support and lenient escape handling via an opt-in Config. Default stays strict (RFC 8259).

Streaming ReaderParser (#132, #257)

rp := jsonparser.NewReaderParser(file)  // any io.Reader
rp.Get("users", "[0]", "name")          // path-based access from a stream

Path-based JSON access from an io.Reader — parse 10GB+ files without loading into memory. Buffers in 64KB chunks; memory bounded by the largest value.

Name aliases (#66)

EachArray, EachObject, EachArrayErr, EachArrayWildcard — canonical EachXxx pattern. Old XxxEach names kept for backward compatibility.

[v1.6.0] — 2026-07-29

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

New API — Append

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

• Append(data, value, keys...) — appends value to the end of the JSON array addressed by keys. Addresses the top-level value when keys is empty; auto-vivifies a missing keyed path as a single-element array. Returns MalformedArrayError when the addressed value is not an array. Traced to SYS-REQ-009, SYS-REQ-110.

Known issues — all resolved (zero open)

• KI-2 fixed — ParseInt("-") now returns an error instead of (0, nil). One-line sign-only guard in bytes.go:parseInt (after stripping the sign byte, an empty remainder returns (0, false, false)).
• KI-3 fixed — Set with an array-index path component under an object parent (and vice-versa) now auto-coerces the container type instead of emitting malformed JSON. (Disposition already set to fixed in v1.5.x.)
• KI-4 fixed — Set on a top-level array-index beyond length now appends at the array's end (matching nested-array behavior under SYS-REQ-110) instead of returning KeyPathNotFoundError. Also cleans up trailing commas in malformed arrays.

Zero open known issues. Every previously shipped known issue is now resolved and covered by ReqProof L3 Assurance.

[v1.5.1] — 2026-07-28

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

Performance — 6.1x large-payload speedup

• Fix stringEnd unbounded backslash scan — stringEndConfig was scanning the ENTIRE remaining parent document for backslashes (bytes.IndexByte(data, '\\')) instead of just the string body. On a 24kb large payload this walked tens of KB per string. Now bounded to data[:firstQuote] (the string body only). 128µs → 22µs (5.8x).
• SWAR string scan — replaced two separate bytes.IndexByte calls (quote + backslash) with a single inline 8-byte SWAR (SIMD-Within-A-Register) loop that checks for both characters simultaneously. 22µs → 21µs (additional 8%).
• Benchmark suite updated — all comparison libraries (gabs, easyjson, ffjson, etc.) updated to latest versions. Benchmark methodology documented (Apple M4 Max, Go 1.26.3, median of 5 runs). The encoding/json benchmark no longer uses ffjson-generated methods (the #126 ffjson measurement bug was fixed in v1.3.1).
• README benchmarks refreshed — all numbers now reflect real measurements on modern hardware with current library versions.

Updated benchmark results (Apple M4 Max, Go 1.26.3, median of 5 runs)

Payload	jsonparser	encoding/json	easyjson	Speedup vs encoding/json
Small (190B, Get)	382 ns	1,335 ns	312 ns	3.5x
Small (190B, EachKey)	241 ns	—	—	5.5x
Medium (2.4kB, Get)	3,894 ns	10,564 ns	2,444 ns	2.7x
Medium (2.4kB, EachKey)	1,923 ns	—	—	5.5x
Large (24kB)	20,788 ns	134,123 ns	32,765 ns	6.4x

All jsonparser results: 0 bytes allocated, 0 allocations.
