From abed3ba46789e7f75e928d0df247e9715c2e3ddf Mon Sep 17 00:00:00 2001 From: Praveen Babu J D Date: Tue, 1 Sep 2026 16:24:57 -0700 Subject: [PATCH 01/46] Extract JSON Schema validation into external pJsonSchemaValidator Move schema validation out of pjson entirely into a standalone ByteDance::pJsonSchemaValidator class declared in the new and implemented in pjson_schema.cpp. The validator is a pure consumer of pjson's public API: it includes only pjson_schema.h (not pjson_internal.h) and touches no library internals, so the core DOM no longer links the schema/regex machinery and programs that never validate do not pull it in. Compile a schema once and reuse the validator across many instances. - Remove pjson::validate() and the nested pjson::SchemaError / pjson::SchemaOptions types; the vocabulary now lives as pJsonSchemaValidator::Error / ::Options (no backward compatibility). - Promote the exact cross-kind numeric ordering the validator needs to a public pjson::tryCompareNumber() method; equality now traverses via the public keys()/find() API. - Migrate all schema/fuzz tests, examples 06/07, the fuzz target/util, and the installed-package consumer smoke test to the new API; add pjson_test::SchemaError/SchemaOptions aliases and schemaValidate() adapters in test_util.h. - Update README, tutorials 06/07, both migration guides, the Doxygen reference + validate-reference.py, CHANGELOG, Todo.md, and the per-requirement response for the extracted validator (SCHEMA-002 and MAINT-002 now done). - Install pjson_schema.h; bump install-consumer version floor to 2.0. Debug/ASan/Release: 483/483 tests pass. Fuzz, examples, docs, and the real find_package install consumer all green.

Tests: +`pjsontest/src/tests_numbers.cpp`, and both SAX/DOM front ends agree +(`tests_depth_frontends.cpp`). + +### PJSON-NUM-002 — Handle non-finite floats explicitly — Implemented +The old behavior (stored NaN/Inf silently serialized as `null`) is replaced by +`SerializeOptions::NonFinitePolicy`. The default `RejectNonFinite` fails +serialization with a structured error (`toString` throws +`std::invalid_argument`; `write` sets `failbit`) identically for compact, +pretty, and streaming output. `NonFiniteToNull` restores the legacy mapping and +`NonFiniteToString` emits `"NaN"`/`"Infinity"`/`"-Infinity"`. Double formatting +remains locale-independent. Tests: `tests_numbers.cpp` +(`non_finite_serialization_policy`, `non_finite_stream_policy`). + +### PJSON-NUM-003 — Define finite float conversion precisely — Partially implemented / already satisfied +The baseline already parsed via a classic-locale conversion, rejected overflow +to non-finite, and round-tripped finite binary64 (verified in +`tests_pathological.cpp` and the new `finite_double_round_trips`). This pass +made the overflow-vs-reject policy explicit through `NumberPolicy`. The formal +"correctly rounded on every standard library" guarantee and the exhaustive +halfway/subnormal randomized-corpus proof described in the requirement remain a +documentation-and-test hardening task (tracked in `Todo.md`); the observable +round-trip contract holds today. + +### PJSON-SEC-001 — Make nesting limits stack-safe — Implemented +Confirmed defect A.4 was real: a large configured `maxDepth` still allowed +recursive DOM/SAX parsing to overflow. Configured depth is now clamped to a +proven-safe hard ceiling (`kParseDepthHardLimit`, 1024) that callers cannot +raise, applied uniformly in the DOM parser and both SAX parsers. A 100,000-deep +document with `maxDepth = INT_MAX` returns a structured resource-limit error +across all front ends. Tests: `tests_depth_frontends.cpp`; clean under ASan. + +### PJSON-PARSE-001 — Keep parser front ends equivalent — Implemented (verified) +Added differential tests asserting the string, byte-span, DOM-stream, +buffered-SAX, and streaming-SAX front ends agree on acceptance, value/structure, +and rejection (including the new numeric-range and depth cases): +`tests_depth_frontends.cpp`. Sharing a single lexer core (PJSON-MAINT-001) +remains deferred; behavioral equivalence is now guarded by tests. + +### PJSON-PARSE-002 — Apply duplicate-key policy early — Implemented +The DOM object parser now decodes the name, checks for a duplicate, and (under +`RejectDuplicateKeys`) fails at the duplicate key's own offset *before* parsing +or allocating its value subtree. Keep-first still grammar-checks the discarded +value. Comparison uses decoded, length-aware names.

Visitors +are function pointers with an opaque `void* ctx` (keeping the public header +declaration-only and ABI-stable); early stop is supported by returning `false`. +`keys()` remains as a convenience copy. Tests: `tests_dom_api.cpp`. + +### PJSON-API-002 — Construction and mutation primitives — Implemented +Added `null()`/`object()`/`array()` factories, `operator=(std::nullptr_t)`, +`pushBack(const pjson&)` and `pushBack(pjson&&)`, `insertOrAssign` (copy and +move), and `reserve()`. Scalar/unsigned/vector assignment and append were +extended for `uint64_t`. Multi-step mutations retain the existing +build-then-swap strong-guarantee pattern. Tests: `tests_dom_api.cpp`. + +### PJSON-API-003 — Separate safe reads from vivifying writes — Implemented +Added checked, non-vivifying `at(key)` and `at(index)` (throwing +`std::out_of_range`) and `contains()` alongside the existing non-vivifying +`find`/`hasKey`/`hasIndex`/`tryGet`. Positive `at(size_t)` uses `size_t`; +negative indexing stays on the separate signed `find(int)`/`tryGet(int, …)` +API. Tests: `tests_dom_api.cpp`. + +### PJSON-API-004 — Type conversion and equality — Implemented (semantics) / Partially (docs) +`tryGet` conversions are exact: signed↔unsigned reads succeed only when +representable, integers widen to double, and no narrowing/precision-losing read +reports success. Cross-representation equality (`1 == 1u == 1.0`) is exact above +2^53 via the rewritten `_compareNumbers`. Object equality is order-independent. +The consolidated prose table enumerating every conversion is folded into the +README numeric/equality sections; a single exhaustive matrix doc is a +documentation follow-up. + +### PJSON-API-005 — Structured error model — Implemented +`ParseError` gained a stable `Code` enum (syntax, invalid encoding, duplicate +key, number range, depth/input/node limits, allocation failure, stream error, +callback error, invalid argument) set alongside the existing message and +byte/line/column. Serialization already reports through exception/`failbit` +with distinct exception types for UTF-8 vs. limit vs. (new) non-finite. Tests: +`tests_error_model.cpp`. A separate `SerializeError` result type is not added; +the existing typed-exception/`failbit` contract satisfies the machine-facing +need. + +### PJSON-API-006 — Ownership and allocator completeness — Already satisfied (documented scope) +The baseline already documents that the custom `Allocator` covers persistent +nodes and string/array/object wrapper objects, while standard-container backing +buffers and transient scratch use the standard allocator, and it is described as +exactly that (not a "complete DOM allocator"). Cross-allocator copy/move/swap +behavior, provenance-preserving deletion, and injected-failure invariants are +covered by `tests_allocator.cpp`. Routing every container's internal buffer +through the allocator is a larger design change left as a documented limitation. + +### PJSON-API-007 — Document thread safety — Implemented (documentation) +pjson makes no positive concurrency guarantee beyond the C++ standard default: +distinct values may be used concurrently; a single value must not be mutated +concurrently with any other access; the default allocator's initialization is +thread-safe. This is now stated explicitly in the README thread-safety note. No +`ThreadSanitizer` job is added because no positive shared-object guarantee is +claimed. + +## 6. P1 serialization + +### PJSON-SER-001 — Valid and stable output — Implemented / already satisfied +Output is one valid RFC 8259 value with correct escaping and programmatic-UTF-8 +validation; `toString()` and `write()` are byte-for-byte equivalent for the +same options; no framing bytes are appended. The output-size limit is now +verified overflow-safe at limit-1/limit/limit+1 for both APIs. Non-finite and +invalid-UTF-8 behavior is defined by policy. Tests: +`tests_serialize_limits.cpp`. + +### PJSON-SER-002 — Deterministic output when requested — Already satisfied (verified) +Sorted (ascending/descending) bytewise key order is available and +deterministic; order does not affect structural equality. Verified by +`deterministic_key_order`. Canonical JSON is explicitly *not* claimed. + +## 7. P1 resource and security + +### PJSON-SEC-002 — Uniform, overflow-safe budgets — Already satisfied / extended +Parser, serializer, patch, and schema budgets exist with a documented "zero = +hard ceiling / unlimited" convention and checked arithmetic. This pass added the +depth hard-ceiling clamp (SEC-001) and kept the number-policy failures +distinguishable from malformed input via `ParseError::Code`. + +### PJSON-SEC-003 — Transactional mutation — Already satisfied (verified) +Patch/Merge Patch remain atomic (build-scratch-then-swap), now using the safe +`_swapStorage` publication path. Move-into-descendant and move-root are +rejected. Covered by `tests_pointer_patch.cpp`. + +### PJSON-SEC-004 — Regexes and external resources hostile — Already satisfied +Schema regex work is size-bounded and screened for catastrophic backtracking by +default (`trustedRegex()` to opt out). No API fetches a URL; remote `$ref` is +rejected. Unchanged and re-verified. + +## 8. Optional JSON Schema module + +### PJSON-SCHEMA-000 — Strict fail-closed subset — Implemented +Added `pJsonSchemaValidator::Options::strict()` / `strictSubset`. In strict +mode, a standard validation/applicator keyword pjson does not enforce (e.g. +`unevaluatedProperties`, `$dynamicRef`) fails validation instead of being +ignored, while unknown non-standard extension keywords remain allowed as +annotations. Default remains permissive for compatibility. Tests: +`tests_schema_2020.cpp`. + +### Schema module extracted to an external validator — Implemented +JSON Schema validation was moved out of `pjson` entirely into the standalone +`ByteDance::pJsonSchemaValidator` class (`` / `pjson_schema.cpp`). +It is a **pure consumer of pjson's public API** and touches no library +internals, so the core DOM no longer carries the schema/regex machinery and +programs that never validate do not link it. The former nested +`pjson::SchemaError` / `pjson::SchemaOptions` are now +`pJsonSchemaValidator::Error` / `pJsonSchemaValidator::Options`, and the +member `pjson::validate()` overloads are removed. Callers construct a validator +from a schema once and reuse it. A new public `pjson::tryCompareNumber()` +promotes the exact cross-kind numeric ordering the validator needs from a +former private helper. This also delivers the compiled/immutable validator +object requested by PJSON-SCHEMA-002. + +### PJSON-SCHEMA-001..006 — Partially implemented / Deferred +This pass materially expanded the validator toward 2020-12 by adding +`if`/`then`/`else`, `prefixItems`, `contains`/`minContains`/`maxContains`, and +`dependentSchemas` (fixing the A.5 conditional-schema gap), plus the strict +gate above, and by extracting a reusable compiled validator object +(SCHEMA-002, above). Not yet implemented: +`$dynamicRef`/`$dynamicAnchor`, `unevaluatedItems`/`unevaluatedProperties`, +`$vocabulary` negotiation, external resolver callbacks, and the full +`draft2020-12` `JSON-Schema-Test-Suite` CI gate. Per the requirement's own +rule, documentation continues to describe this as a **documented subset** and +does not claim general 2020-12 conformance. Remaining SCHEMA-001/003/004/006 +work is tracked in `Todo.md` as a separately gated module effort. + +## 9. Existing extensions + +### PJSON-EXT-001/002/003 — Pointer / Patch / Merge Patch — Already satisfied +RFC 6901/6902/7396 behavior, atomicity, and structured errors were already +implemented and tested; embedded-NUL and aliasing fixes above strengthen them. +Re-verified by `tests_pointer_patch.cpp`. + +## 10. P2 performance + +### PJSON-PERF-001/002/003 — Deferred +The comparative benchmark harness (`bench/`) and methodology already exist. The +broader per-workload matrix, regression tracking on controlled runners, and the +"avoid avoidable work" audit are performance projects deferred to a follow-up so +this pass could keep correctness gates as the priority. The new unsigned path +and traversal API were written to avoid extra allocations/copies. + +## 11. P2 build, packaging, portability + +### PJSON-BUILD-001..005 — Already satisfied (verified) +The baseline is a well-behaved CMake subproject (namespaced `pjson::pjson`, +developer targets off when embedded), supports static/shared install and +build-tree consumers, ships relocatable CMake + pkg-config + Conan/vcpkg +recipes, publishes a CI platform matrix (GCC/Clang/AppleClang/MSVC), and keeps +optional features modular. Version fields were bumped to 2.0.0 across the header, +CMake, Conan, and vcpkg manifests (a configure-time mismatch is a hard error). + +## 12. Verification + +### PJSON-TEST-001..005 — Partially implemented / already satisfied +JSONTestSuite and the JSON-Schema-Test-Suite (draft-07) are pinned and wired; +sanitizer, differential, and fuzz jobs exist. This pass added the two mandatory +regressions (embedded-NUL access; ancestor/descendant move under sanitizers) and +new differential front-end tests, and every compiled case remains individually +registered with CTest (483 cases). The `draft2020-12` conformance gate is +deferred with the full-dialect work (SCHEMA-006). + +## 13. Documentation and governance + +### PJSON-DOC-001..004 — Partially implemented +README, `CHANGELOG.md`, and `Todo.md` are updated for the new numeric model, +non-finite policy, error codes, traversal/factory/checked APIs, and schema +additions, and the 2.0.0 compatibility impact is called out (ABI break + +behavioral changes) per DOC-004. `SECURITY.md`/`GOVERNANCE.md` already cover +DOC-003. A single consolidated behavioral-contract reference (DOC-001) remains a +documentation follow-up. + +## 14. Maintainability + +### PJSON-MAINT-001/002 — MAINT-002 implemented / MAINT-001 deferred +Unifying the DOM and SAX grammar into one shared core (MAINT-001) remains an +architectural-debt item in `Todo.md`. Splitting the schema validator out of the +DOM translation unit (MAINT-002) is done: it now lives in its own +`pjson_schema.cpp` behind the external `pJsonSchemaValidator` class, decoupled +from the DOM via the public API. Both are guarded by the differential and schema +tests. + +## 15. P3 optional enhancements — Deferred +Insertion-order object storage, big-integer/decimal types, `string_view` +overloads, JSON Lines helpers, canonical JSON, and a pull-parser cursor remain +optional and out of scope; several are listed in `Todo.md`. + +## 16–17. Delivery sequence and definition of done + +Steps 1–6 of the requirement's own delivery order (the core correctness gate) +are complete: embedded-NUL keys, aliasing safety, exact unsigned integers, the +non-finite policy, stack-safe/equivalent front ends, and early duplicate +detection with structured diagnostics — each with a permanent regression test +and clean under ASan/UBSan. Step 7 (traversal, generic insertion, factories, +checked indexing) and the structured-error portion of step 6 are done. The full +JSON Schema 2020-12 module (step 10) is advanced but intentionally still labeled +a documented subset, and steps 9/11 (performance baselines, registry publishing) +plus the deferred items above remain open and tracked in `Todo.md`. diff --git a/docs/featurerequest.md b/docs/featurerequest.md new file mode 100644 index 0000000..d1fb87a --- /dev/null +++ b/docs/featurerequest.md @@ -0,0 +1,1063 @@ +# pjson Production-Readiness Requirements + +Status: Proposed +Baseline reviewed: pjson 1.0.0, commit 843930fbf2ec0ca6e2edc9fdc60aad6e27ed9cb6 +Scope: the standalone pjson library and its optional standards modules + +## 1. Purpose + +This document defines the correctness, safety, API, standards-conformance, +performance, testing, packaging, and maintenance requirements for pjson to be a +dependable general-purpose C++ JSON library. It is intentionally independent of +any particular downstream project, application, or protocol. + +The requirements are observable contracts. Implementations may change as long +as the contracts and acceptance criteria remain satisfied. + +The key words MUST, MUST NOT, SHOULD, SHOULD NOT, and MAY are to be interpreted +as described by RFC 2119 and RFC 8174. + +## 2. Product goals + +pjson should provide: + +- strict and predictable RFC 8259 parsing and serialization; +- lossless handling of every value represented by its documented data model; +- safe processing of untrusted input under explicit resource budgets; +- a compact but complete DOM API for construction, inspection, traversal, and + mutation; +- consistent behavior across DOM, SAX, string, byte-span, and stream APIs; +- optional standards modules whose conformance level is explicit and testable; +- portable build and package integration; and +- evidence-based performance and reliability claims. + +The following are not required goals: + +- being header-only; +- preserving source key order unless an explicit storage policy requests it; +- silently accepting malformed or implementation-defined JSON; +- implicit network access for external references; or +- being the fastest library on every workload. + +## Normative references + +The implementation and its conformance claims should be evaluated against the +published standards rather than another library's behavior: + +- [RFC 8259 — The JavaScript Object Notation Data Interchange Format](https://www.rfc-editor.org/rfc/rfc8259) +- [ECMA-404 — The JSON Data Interchange Syntax](https://ecma-international.org/publications-and-standards/standards/ecma-404/) +- [RFC 6901 — JavaScript Object Notation Pointer](https://www.rfc-editor.org/rfc/rfc6901) +- [RFC 6902 — JavaScript Object Notation Patch](https://www.rfc-editor.org/rfc/rfc6902) +- [RFC 7396 — JSON Merge Patch](https://www.rfc-editor.org/rfc/rfc7396) +- [JSON Schema Draft 2020-12](https://json-schema.org/draft/2020-12/) +- [Semantic Versioning 2.0.0](https://semver.org/spec/v2.0.0.html) + +Where a standard permits implementation-defined behavior, pjson MUST document +its chosen behavior and test it consistently across all relevant APIs. + +## 3.

The core +DOM may be production-ready without that component, but the project MUST NOT +claim conformance that the optional component has not achieved. + +## 4. P0 correctness and safety requirements + +### PJSON-COR-001: Preserve object keys byte-for-byte + +JSON object names are strings and may contain embedded U+0000. Every API that +accepts a length-aware string MUST preserve the complete byte sequence and MUST +NOT route it through a NUL-terminated representation. + +Required behavior: + +- std::string lookup, insertion, assignment, tryGet, hasKey, and erase paths + MUST use both the pointer and length. +- A string-view API MUST also be length-aware. For C++11, a library-defined + view or a (const char*, size_t) overload is acceptable. +- const char* overloads MAY retain conventional NUL-terminated behavior, but + this distinction MUST be documented. +- Parsed names "a" and "a\u0000b" MUST remain distinct. +- JSON Pointer escaping, lookup, Patch, Merge Patch, equality, copying, and + serialization MUST preserve such names. + +Acceptance tests MUST cover empty names and U+0000 at the beginning, middle, +and end of a name through const and mutable APIs. At minimum, parsing an object +containing both "a" and "a\u0000b" must allow the two values to be found, +updated, and erased independently. + +### PJSON-COR-002: Make aliasing mutations memory-safe + +Every public copy, move, assignment, swap, and mutation operation MUST have +defined behavior when its source aliases the destination, including when one +operand is an ancestor or descendant of the other. It MUST NOT cause +use-after-free, double-free, ownership cycles, leaks, or partially committed +state. + +The implementation MAY complete an operation from a temporary snapshot or +reject an unsupported relationship before mutation. If rejection is chosen, +the API MUST expose it deterministically; an undocumented undefined-behavior +precondition is not acceptable. A noexcept API must use a non-throwing error +result, a documented safe no-op, or another explicit mechanism. + +Acceptance tests MUST cover: + +- self-copy and self-move; +- assigning a root from one of its descendants; +- assigning a descendant from its root; +- assignments between siblings; +- swapping a root and descendant; +- same-allocator and cross-allocator cases; and +- allocation failure during paths that take a defensive copy. + +All cases MUST run under AddressSanitizer, UndefinedBehaviorSanitizer, and leak +checking. This pattern, in particular, must never access freed storage: + +~~~cpp +pjson root; +root["child"]["value"] = std::int64_t{7}; +pjson& child = root["child"]; +root = std::move(child); +~~~ + +### PJSON-NUM-001: Never silently corrupt an accepted number + +The library MUST define an explicit numeric model and preserve every value it +claims to represent. A syntactically valid integer token MUST NOT be silently +rounded into a different value merely because it is outside int64_t. + +At minimum, the DOM and SAX APIs MUST support the complete int64_t and uint64_t +ranges exactly. The public API MUST provide: + +- a distinct unsigned integer representation, such as jsonNumberUInt; +- assignment and construction from uint64_t; +- isUInt() and tryGet(uint64_t&); +- an unsigned SAX event, such as onUInt(uint64_t); +- array and vector insertion support for unsigned integers; +- exact signed/unsigned/double comparison semantics; and +- decimal serialization without conversion through double. + +For backward compatibility, integer tokens from zero through INT64_MAX MAY +remain stored as signed integers. Tokens from INT64_MAX + 1 through UINT64_MAX +MUST be stored as unsigned integers. An explicit uint64_t assignment SHOULD +retain unsigned type identity even when its value is small. + +Integer tokens outside the supported exact range MUST either: + +1. be rejected with a structured out-of-range error; or +2. be preserved through an explicitly documented exact decimal or big-integer + representation. + +Lossy conversion to double MUST require an explicit opt-in policy. + +Acceptance tests MUST include: + +- INT64_MIN, INT64_MIN - 1, -1, 0, 2^53 - 1, 2^53, 2^53 + 1, + INT64_MAX, INT64_MAX + 1, UINT64_MAX, and UINT64_MAX + 1; +- construction, parsing, SAX events, extraction, comparison, copying, moving, + Patch test, schema numeric comparison, and serialization; and +- identical numeric classification across all parser front ends and arbitrary + input chunk boundaries. + +### PJSON-NUM-002: Handle non-finite floating-point values explicitly + +JSON has no NaN or infinity values. A stored NaN or infinity MUST NOT silently +serialize as JSON null, because that changes both type and value while reporting +success. + +The default policy MUST do one of the following: + +- reject non-finite assignment; or +- retain the value in the DOM but make every serialization API fail with a + structured error. + +An explicit opt-in conversion policy MAY map non-finite values to null or +strings, but it MUST never be the implicit default. Compact, pretty, buffered, +and streaming output MUST follow the same policy. + +Double formatting MUST be locale-independent and use +std::numeric_limits::max_digits10 or a proven shortest-round-trip +algorithm rather than a hard-coded assumption about binary64 precision. + +Tests MUST cover positive and negative infinity, quiet and signaling NaNs where +the platform provides them, negative zero, the smallest subnormal, the largest +finite value, and root and nested positions. + +### PJSON-NUM-003: Define finite floating-point conversion precisely + +Parsing a decimal JSON number into binary floating point is inherently a +conversion. The parser MUST document its supported floating-point domain and +MUST use a locale-independent, correctly rounded conversion where the platform +permits it. + +Required behavior: + +- finite values within the supported range MUST parse deterministically; +- overflow MUST fail with a structured numeric-range error; +- underflow that would silently change a nonzero token to zero MUST either fail + by default or require an explicit lossy-conversion policy; +- the sign of negative zero MUST have a documented parse, equality, extraction, + and serialization policy; +- serialization followed by parsing MUST recover the same finite double bits, + except where a clearly documented normalization policy applies; and +- parsing and formatting MUST not depend on the process locale or rounding + mode without explicitly documenting that dependency. + +Tests MUST cover halfway cases, subnormals, exponent extremes, negative zero, +all rounding boundaries around 2^53, and randomized binary64 round trips on +every supported standard-library implementation. + +### PJSON-SEC-001: Make nesting limits stack-safe + +User-configurable resource limits MUST NOT allow callers to disable memory +safety. If a parser or tree algorithm is recursive, accepting an arbitrarily +large depth limit can exhaust the native stack. + +The parser MUST either: + +- use an iterative state machine whose nesting storage is heap-bounded; or +- clamp configured depth to a documented hard maximum proven safe on every + supported platform. + +The same rule applies to schema validation, equality, copying, destruction, +serialization, Pointer, Patch, and Merge Patch. Existing iterative algorithms +must remain iterative. + +Acceptance tests MUST pass a very large requested depth, including INT_MAX, +then process deeply nested arrays and objects without stack overflow. DOM, SAX, +buffered-stream, and chunked-stream entry points MUST return a resource-limit +error under sanitizers rather than terminate the process. + +### PJSON-PARSE-001: Keep all parser front ends behaviorally equivalent + +The string, byte-span, DOM stream, buffered SAX, and incremental SAX APIs MUST +use the same JSON grammar and semantic policies. For equivalent input and +options, they MUST agree on acceptance, decoded values or events, +duplicate-key behavior, number classification, resource accounting, and the +first relevant error location. + +Required edge cases include: + +- empty input and every valid top-level scalar type; +- trailing JSON values, trailing non-whitespace bytes, and embedded NUL bytes; +- malformed and truncated UTF-8 at every byte boundary; +- escaped Unicode and surrogate pairs split across stream chunks; +- malformed numbers and very long number tokens; +- arrays and objects split at every possible one-to-four-byte boundary; and +- cancellation or exceptions from SAX callbacks. + +DOM and SAX implementations SHOULD share a lexer/parser core to reduce future +behavioral drift. + +### PJSON-PARSE-002: Apply duplicate-key policy early and consistently + +Duplicate detection MUST compare decoded, length-aware names. Under the reject +policy, the parser SHOULD report a duplicate immediately after the second name +is decoded, before allocating or traversing its value subtree. + +Under keep-first, the duplicate value MUST still be checked for valid JSON and +charged against input and work budgets, but the implementation SHOULD avoid +building an unused DOM subtree. Under keep-last, replacement MUST provide a +clear exception-safety guarantee. DOM and SAX behavior MUST be documented where +an event stream cannot retract an earlier value. + +Tests MUST cover identical, escaped-equivalent, embedded-NUL, and nested names; +malformed duplicate values; large duplicate subtrees; and all three policies. + +## 5. P1 core DOM and API requirements + +### PJSON-API-001: Provide non-allocating traversal + +The DOM MUST provide direct, non-owning traversal for arrays and objects without +copying every object name or performing a second lookup per member. Acceptable +designs include iterator and range types or callback-based visitors. + +The API MUST provide: + +- const array traversal; +- mutable array-value traversal; +- const object traversal exposing a length-aware key view and value reference; +- mutable object-value traversal without allowing in-place key corruption; and +- documented iterator and reference invalidation rules for insert, erase, + clear, move, swap, and type-changing mutation. + +keys() MAY remain as a convenience copy API. Tests and benchmarks MUST verify +that the direct traversal path performs no per-key allocations. + +### PJSON-API-002: Complete construction and mutation primitives + +The library SHOULD offer explicit, unambiguous ways to create and mutate each +JSON kind: + +- null(), object(), and array() factories or equivalent tagged constructors; +- assignment from std::nullptr_t; +- scalar constructors and assignments for strings, booleans, signed integers, + unsigned integers, and doubles; +- pushBack(const pjson&), pushBack(pjson&&), and an emplacement equivalent; +- object insert-or-assign operations accepting copied and moved pjson values; +- optional initializer-list factories with unambiguous object and array syntax; + and +- reserve() for arrays and any object representation where reservation is + meaningful. + +Default construction MAY continue to mean JSON null. Callers must not need to +rely on default construction having an implicit object or array type. + +All multi-step mutations MUST document and test their exception guarantee. A +failed allocation SHOULD leave the destination unchanged; where that is not +possible, the exact valid postcondition MUST be documented. + +### PJSON-API-003: Separate safe reads from vivifying writes + +Mutating operator[] MAY create missing nodes, but read-only access MUST NOT +mutate the document. The public API SHOULD include: + +- find(key or index), returning a pointer or nullable view; +- contains(key) or hasKey(key), and hasIndex(index); +- checked at(key or index), with a documented exception or result type; +- strict tryGet functions that leave outputs unchanged on failure; and +- convenience getOr functions whose conversions are explicit and checked. + +Positive array indexing SHOULD use size_t. If negative indexing remains, it +SHOULD use a separately named signed-index API. Out-of-range negative indexes +MUST NOT silently clamp to element zero. + +### PJSON-API-004: Define type conversion and equality precisely + +The documentation MUST define: + +- which conversions are exact, widening, narrowing, or forbidden; +- whether 1, unsigned 1, and 1.0 compare equal; +- exact behavior above 2^53; +- negative-zero behavior; +- whether numeric type identity survives parse and serialization; +- object equality independent of storage or serialization order; and +- equality behavior for values using different allocators. + +No narrowing or precision-losing tryGet operation may report success. Checked +conversion APIs MAY be supplied for callers that explicitly request narrowing. + +### PJSON-API-005: Provide a structured error model + +Human-readable messages are useful but insufficient as the only machine-facing +error contract. Parsing and serialization SHOULD expose stable error categories +in addition to text. At minimum, distinguish: + +- syntax error; +- invalid UTF-8 or escape; +- duplicate key; +- numeric overflow, underflow, or unsupported exact number; +- depth, input-byte, node, work, and output-byte limits; +- allocation failure; +- stream read or write failure; +- callback cancellation or exception; and +- invalid API argument. + +Parse diagnostics MUST retain byte offset, one-based line, and documented +column semantics. A non-throwing serialization overload SHOULD return a result +or populate a SerializeError; callers should not need to infer the cause from +ostream failbit. + +### PJSON-API-006: Make ownership and allocator behavior complete + +If the library advertises allocator-aware storage, the contract MUST state +exactly which allocations use the supplied allocator. Prefer routing all +persistent DOM allocations through it, including node objects, strings, object +names, and array and object backing storage. Otherwise, describe the feature as +a node allocator rather than a complete DOM allocator. + +Required guarantees: + +- an allocator outlives every value bound to it; +- destruction always uses the originating allocator; +- cross-allocator copy, move, and swap behavior is explicit; +- parsed ownership cannot be detached and deleted incorrectly; +- failure injection at every persistent allocation site leaves a valid tree; + and +- iterative destruction remains safe for very deep documents. + +### PJSON-API-007: Document thread safety + +The project MUST state whether: + +- separate values can be used concurrently; +- one immutable value can be read concurrently; +- mutation requires exclusive synchronization; +- custom allocators must provide their own synchronization; and +- global or default allocator and version functions are initialization-safe. + +Any positive thread-safety guarantee MUST have a ThreadSanitizer test. + +## 6. P1 serialization requirements + +### PJSON-SER-001: Guarantee valid and stable JSON output + +Every successful serializer MUST emit exactly one valid RFC 8259 JSON value. It +MUST correctly escape values and names, validate programmatically supplied +UTF-8, and never append framing bytes such as a newline unless explicitly +requested. + +The contract MUST specify: + +- compact versus pretty output; +- key-order policy; +- Unicode and solidus escaping policies; +- floating-point formatting; +- behavior for invalid UTF-8 and non-finite values; +- maximum output size; and +- whether a stream failure can leave partial output. + +toString() and streaming write() MUST be semantically equivalent for the same +options. Output-size checks MUST be overflow-safe and tested at limit minus one, +the exact limit, and limit plus one. + +### PJSON-SER-002: Preserve deterministic output when requested + +The library MUST provide a deterministic object-key order. Sorted bytewise +order is sufficient and matches the current representation. If insertion-order +storage is added, callers MUST still be able to request sorted output. + +Canonical JSON is a separate feature and MUST NOT be claimed unless all rules +of a named canonicalization specification are implemented and tested. + +## 7. P1 resource and security requirements + +### PJSON-SEC-002: Use uniform, overflow-safe resource budgets + +Every operation that can scale with untrusted input SHOULD accept or inherit an +explicit budget. Applicable limits include: + +- input bytes; +- nesting depth; +- materialized nodes; +- decoded string and name bytes; +- number-token length; +- total parser work; +- serialized output bytes; +- Patch operations, cloned nodes and bytes, and pointer traversal; +- schema depth, reference resolutions, regex work, validation work, and error + count; and +- stream token buffering. + +All size arithmetic MUST be checked before addition or multiplication. A zero +limit MUST have one consistent documented meaning; it must not mean unlimited +for one budget and use the hard ceiling for another without an explicit type or +name distinguishing those policies. + +Resource-limit failures MUST be distinguishable from malformed input and +allocation failure. Defaults MUST be finite and suitable for untrusted input. +Applications MAY explicitly opt into larger limits, subject to stack-safe hard +ceilings. + +### PJSON-SEC-003: Preserve transactional mutation guarantees + +Patch and Merge Patch MUST remain atomic: syntax, lookup, failed test, budget, +and allocation failures leave the original target unchanged. Other compound +mutations SHOULD offer the strong exception guarantee. + +Pointer and Patch implementations MUST handle deeply nested and adversarial +paths without integer overflow or unbounded recursion. Move operations MUST NOT +create ownership cycles. + +### PJSON-SEC-004: Treat regexes and external resources as hostile + +Any regex-processing feature MUST bound both pattern and subject work or use an +engine with a reliable complexity guarantee. Disabling protections MUST require +an explicit trusted-input option. + +No API may fetch a URL merely because input contains one. Optional external +resource resolution MUST be callback-driven and disabled by default, with +caller-controlled scheme and host allowlists, byte limits, timeouts, redirect +policy, recursion limits, and caching. + +## 8. Optional JSON Schema module requirements + +JSON Schema is not required for a useful JSON DOM. However, if pjson advertises +general JSON Schema support rather than a named subset, the following are +requirements. Keeping this functionality in an optional pjson-schema target is +encouraged so the core library remains small. + +### PJSON-SCHEMA-000: Make subset validation fail closed when requested + +Even without full dialect support, the schema component MUST provide a strict +subset mode suitable for validation boundaries. In that mode it MUST reject: + +- unsupported standard validation or applicator keywords; +- malformed values for supported keywords; +- unresolved or unsupported references; and +- a declared dialect or required vocabulary it cannot implement. + +It MAY allow unknown extension keywords as annotations under an explicit +policy. Permissive behavior that ignores unsupported constraints MAY remain +available for backward compatibility, but it MUST be clearly named, documented, +and opt-in for new code. A caller must be able to determine whether every +validation-relevant part of a schema was understood before trusting the result. + +### PJSON-SCHEMA-001: Implement an explicit dialect contract + +The schema API MUST accept a default dialect option and honor $schema when +present. It MUST support JSON Schema Draft 2020-12 completely before claiming +2020-12 conformance. Additional dialects, such as Draft 7, MAY be supported. +Unsupported dialects and required vocabularies MUST produce a clear error. + +Unknown extension keywords must be handled according to the selected dialect; +they must not be confused with unsupported required vocabularies. + +### PJSON-SCHEMA-002: Compile and validate schemas separately + +Provide a compiled, immutable schema object. Compilation MUST: + +- validate the schema against the appropriate meta-schema when strict schema + checking is enabled; +- reject malformed shapes for known keywords in strict mode; +- resolve identifiers, anchors, dynamic anchors, and references; +- detect invalid reference graphs and enforce reference and work budgets; and +- avoid repeating compilation for every instance validation. + +Compiled schemas SHOULD be safe for concurrent validation when callers use +separate diagnostic sinks. + +### PJSON-SCHEMA-003: Cover the Draft 2020-12 vocabulary + +The implementation MUST cover the applicable 2020-12 Core, Applicator, +Validation, Unevaluated, and Metadata vocabularies, including at least: + +- $schema, $id, $vocabulary, $defs, $anchor, $dynamicAnchor, $ref, + $dynamicRef, and $comment; +- allOf, anyOf, oneOf, not, if, then, and else; +- prefixItems, items, contains, minContains, and maxContains; +- properties, patternProperties, additionalProperties, propertyNames, and + dependentSchemas; +- unevaluatedItems and unevaluatedProperties; +- type, enum, const, multipleOf, numeric bounds, string lengths and patterns, + array size and uniqueness, object size, required, and dependentRequired; and +- annotations such as title, description, default, deprecated, readOnly, + writeOnly, and examples. + +Format annotation and assertion behavior MUST be selectable and documented. +Supported formats MUST be listed individually. Content vocabulary and +nonstandard formats MAY be optional, but unsupported behavior must be explicit. +Regular-expression behavior MUST follow the dialect's required ECMA-262 model +closely enough to pass its official tests; using a platform regex engine is not +by itself evidence of compatibility. + +### PJSON-SCHEMA-004: Make reference resolution secure and embeddable + +Local fragment and URI resolution MUST follow the selected JSON Schema dialect. +Remote references MUST never trigger implicit network access. Applications MAY +provide a resolver callback that returns schema bytes or DOM values. Resolution +MUST enforce cycle detection, depth, document-count, total-byte, and work +limits. + +Failure to resolve a required reference MUST fail compilation or validation; it +MUST NOT silently make the schema permissive. + +### PJSON-SCHEMA-005: Provide actionable diagnostics + +Each schema compilation or validation error SHOULD include: + +- a stable error code; +- instance location as a JSON Pointer; +- schema or keyword location as a URI or JSON Pointer; +- keyword name; +- human-readable message; and +- nested causes for combinators when requested. + +Callers MUST be able to choose first-error or bounded multi-error collection. +Diagnostic collection itself must respect an error-count and memory budget. + +### PJSON-SCHEMA-006: Prove conformance + +The full applicable JSON-Schema-Test-Suite Draft 2020-12 corpus MUST run in CI. +Skipped groups and deliberate deviations MUST be machine-readable, reviewed, +and published. A missing corpus must fail release CI rather than produce a +successful skip. + +Tests MUST also cover malformed schemas, vocabulary negotiation, reference +cycles, external resolver failures, regex limits, validation budgets, Unicode +length, exact mixed numeric comparisons, and boolean schemas. + +Until these requirements are met, documentation and package metadata MUST say +documented JSON Schema subset, name the supported keyword set, and prominently +state that unknown or unsupported constraints may be ignored. + +## 9. Existing extension requirements + +### PJSON-EXT-001: JSON Pointer + +JSON Pointer behavior MUST conform to RFC 6901 for string and URI-fragment forms +if both are exposed. Tests MUST include empty tokens, ~0, ~1, embedded NUL, +non-ASCII names, invalid escapes, large indices, leading-zero indices, and the +array dash token where applicable. Lookups MUST be non-vivifying. + +### PJSON-EXT-002: JSON Patch + +JSON Patch behavior MUST conform to RFC 6902. All operations must be atomic as +a document, and test MUST use the documented structural and numeric equality +rules. Tests MUST cover root replacement and removal, same-array moves, +descendant moves, invalid paths, duplicate members in the patch document, +budget failure, and allocation failure. + +### PJSON-EXT-003: JSON Merge Patch + +JSON Merge Patch behavior MUST conform to RFC 7396, including root replacement, +null member deletion, and wholesale array replacement. Deep patches must be +stack-safe and atomic under allocation or budget failure. + +## 10. P2 performance requirements + +### PJSON-PERF-001: Maintain representative benchmarks + +Benchmarks MUST separately measure parse, compact serialization, traversal, +copy, move, and allocation behavior for: + +- small request and response documents; +- medium nested documents; +- large documents; +- wide objects; +- large arrays; +- string-heavy and escape-heavy data; +- integer-heavy and floating-point-heavy data; and +- optional caller-supplied real-world corpora. + +Comparison runs SHOULD include current releases of several established DOM +libraries, including at least one feature-rich implementation and one +performance-oriented implementation. Results MUST record commit, compiler, +flags, architecture, operating system, allocator, input sizes, and methodology. + +No performance claim should rely on a single machine, best-case sample, or one +workload. Median latency, throughput, peak resident memory, allocation count, +compiled object size, final binary size, and clean and incremental compilation +time SHOULD be reported separately. + +### PJSON-PERF-002: Avoid avoidable work in common DOM operations + +The common paths SHOULD support: + +- one-lookup object access; +- traversal without copied key lists; +- moved child insertion without deep copying; +- array capacity reservation and amortized append; +- direct serialization to a caller-provided sink; +- schema compilation reuse; and +- parsing from byte spans without an intermediate NUL-terminated copy. + +Performance changes MUST preserve all safety budgets and MUST be checked by +correctness tests and sanitizers. + +### PJSON-PERF-003: Track regressions without overclaiming + +CI SHOULD retain historical benchmark artifacts or compare against the last +stable release on controlled runners. Initially, regressions larger than an +agreed threshold should produce a report rather than a flaky pass or fail. +Once runner stability is demonstrated, release gates MAY enforce per-workload +budgets. + +## 11. P2 build, packaging, and portability requirements + +### PJSON-BUILD-001: Be a well-behaved CMake subproject + +The project MUST export a namespaced target such as pjson::pjson and MUST NOT +modify parent-wide compiler flags, warning levels, language standards, +BUILD_TESTING, or unrelated cache variables when included with +add_subdirectory() or FetchContent. Developer-only tests, examples, benchmarks, +documentation, fuzzers, and install rules MUST default off when the project is +embedded. + +The minimum CMake version SHOULD be no higher than required by the library +implementation. CMake 3.15 compatibility is a useful portability target. If a +newer minimum remains necessary, the exact feature requiring it MUST be +documented and direct-source integration must remain supported. + +### PJSON-BUILD-002: Support static and shared consumption correctly + +Static and shared builds MUST work through build-tree and installed-package +usage. Public symbol visibility and export macros SHOULD be explicit rather +than depending solely on automatic Windows symbol export. Position-independent +code, runtime-library selection, and debug and release configuration handling +MUST behave correctly on supported platforms. + +Installed CMake and pkg-config metadata MUST be relocatable, contain no source +or build paths, and expose only actual consumer dependencies. + +### PJSON-BUILD-003: Publish immutable package inputs + +Release tags MUST be immutable and resolve to reviewed commits. Release source +archives and artifacts MUST include checksums. Package recipes SHOULD use an +immutable tag or commit plus a cryptographic hash rather than building a mutable +checkout. + +Official or documented recipes SHOULD cover Conan and vcpkg once their registry +submission and maintenance status are clear. Static and shared package +consumers MUST be built and executed in CI. + +### PJSON-BUILD-004: Define the supported platform matrix + +The project MUST publish its supported combinations of operating system, +architecture, compiler, standard library, C++ language level, and build type. +CI MUST exercise every combination claimed as supported or clearly distinguish +fully tested platforms from best-effort platforms. At minimum, the expected +general-purpose matrix is: + +- GCC and Clang on Linux; +- AppleClang on macOS; +- MSVC on Windows; +- x86-64 and arm64 where hosted runners are available; and +- Debug and optimized Release builds. + +If MinGW, 32-bit targets, Android, unusual double formats, or big-endian targets +are claimed, they require corresponding CI or periodic verification. + +### PJSON-BUILD-005: Keep optional features modular + +The RFC 8259 parser, serializer, and DOM SHOULD remain usable without JSON +Schema, regular-expression, networking, or benchmark dependencies. Optional +standards modules SHOULD have separate targets and headers with explicit +dependency and version contracts. Disabling an optional module MUST remove its +code and transitive dependencies from consumer builds. + +## 12. P1 and P2 verification requirements + +### PJSON-TEST-001: Keep conformance corpora mandatory for releases + +Release CI MUST fetch commit-pinned and integrity-verified conformance corpora +and fail if they are absent, empty, at the wrong revision, or produce an +unexpected case count. A local developer build MAY skip unavailable optional +corpora, but the skip must be conspicuous. + +Required suites include: + +- JSONTestSuite for parser acceptance and rejection; +- JSON-Schema-Test-Suite for every claimed schema dialect and vocabulary; and +- maintained RFC 6901, RFC 6902, and RFC 7396 cases for extension APIs. + +Accepted implementation-defined parser cases SHOULD be checked for structural +equality and stable reserialization, not only successful reparsing. + +### PJSON-TEST-002: Run differential and property tests + +The project SHOULD maintain tests for: + +- DOM versus SAX acceptance and value or event equivalence; +- string versus byte-span versus stream parsing; +- compact output reparsing to structural equality; +- stream output matching buffered output; +- copy, move, and swap invariants; +- Patch and Merge Patch atomicity; +- allocator provenance and injected allocation failure; and +- comparisons against one or more mature JSON implementations on the common, + standards-defined subset. + +Differences from comparison libraries MUST be placed in a small reviewed +allowlist with a reason and an expiry or review condition. + +### PJSON-TEST-003: Strengthen fuzzing + +Maintain separate fuzzers for DOM parsing, SAX and stream parsing, +serialization, Pointer and Patch, Merge Patch, and schema compilation and +validation. Fuzz invariants SHOULD include: + +- no crash, leak, undefined behavior, or unbounded work within configured + limits; +- DOM and SAX acceptance parity; +- parse of serialize producing structural equality for representable values; +- equivalent buffered and chunked-stream behavior; +- failed transactional operations leaving inputs unchanged; and +- diagnostics remaining within configured budgets. + +Smoke fuzzing MUST include inputs larger than 4 KiB as well as targeted seeds +for Unicode boundaries, embedded NUL, duplicate names, long numbers, deep and +wide containers, output limits, and aliasing mutations. Prefer active +continuous hosted fuzzing; otherwise run scheduled sustained fuzz jobs and +retain and minimize all findings. + +### PJSON-TEST-004: Require sanitizers and static analysis + +Every release candidate MUST pass the complete unit and conformance suite with: + +- AddressSanitizer; +- UndefinedBehaviorSanitizer; +- leak detection on a supported platform; and +- compiler warnings treated as errors for project sources. + +ThreadSanitizer SHOULD cover any documented concurrent-use guarantees. Memory +Sanitizer SHOULD only be claimed when the whole relevant dependency graph is +instrumented. If a sanitizer option is unsupported by the selected toolchain, +configuration MUST fail clearly rather than silently ignoring the request. + +Static analysis and CodeQL SHOULD remain enabled. Findings must be triaged, and +release criteria must require zero unresolved high-severity correctness or +security findings. + +### PJSON-TEST-005: Add regression tests for every defect + +Every correctness or security fix MUST first gain a minimal reproducer and then +retain it as a permanent test. The two initial mandatory regressions are: + +1. length-preserving access to an embedded-NUL object name; and +2. ancestor and descendant move assignment under sanitizers. + +The test suite must register every compiled case with the test runner. Release +CI SHOULD compare discovered and registered counts to prevent silent omission. + +## 13. P2 documentation and API-governance requirements + +### PJSON-DOC-001: Publish one precise behavioral contract + +Versioned documentation MUST define: + +- every JSON value representation and numeric boundary; +- parsing strictness, duplicate handling, and resource-limit defaults; +- error and exception behavior for each entry point; +- construction, auto-vivification, and null semantics; +- iterator, pointer, reference, and string-view invalidation; +- copy, move, swap, allocator, and aliasing behavior; +- serialization ordering, escaping, and numeric formatting; +- thread-safety guarantees; and +- exact conformance scope for every optional standard. + +Examples MUST use safe, non-vivifying APIs for reads and must not depend on +undocumented behavior. + +### PJSON-DOC-002: Maintain compatibility and migration guidance + +Semantic Versioning MUST cover documented source and behavioral contracts. If +ABI stability is not promised, documentation must state that consumers should +rebuild the library and dependents together. + +For each release, publish: + +- added, changed, deprecated, removed, fixed, and security-relevant behavior; +- migration notes for behavior changes; +- supported compiler and platform matrix; +- conformance-suite revisions and results; and +- benchmark methodology and comparison caveats. + +Changes to enum values, object ordering, number classification, duplicate-key +defaults, exception behavior, or serialization are compatibility changes and +must be versioned deliberately. Existing enum numeric values SHOULD NOT be +renumbered when an unsigned kind is added. + +### PJSON-DOC-003: Keep security and maintenance expectations explicit + +Maintain a private vulnerability-reporting path, supported-version table, +response targets, and coordinated-disclosure policy. Repository governance must +identify active maintainers and the process for reviewing significant API, +security, or compatibility changes. + +### PJSON-DOC-004: Classify compatibility impact before implementation + +Each requirement must be assigned a release-compatibility impact before its +implementation is merged: + +| Change class | Typical impact | +| --- | --- | +| Fix incorrect lookup or memory-unsafe behavior | Patch release, with regression tests | +| Add new overloads, factories, traversal, or structured errors | Minor release when source-compatible | +| Add a numeric variant that changes class layout | ABI break; require dependent binaries to rebuild and document it prominently | +| Change duplicate-key defaults, non-finite handling, numeric classification, or serialized spelling | Behavioral compatibility change; provide migration notes and use the SemVer level required by the published contract | +| Add a separate optional schema module | Minor release when it does not alter core behavior | +| Change object storage or iteration invalidation rules | Potential source, behavioral, and ABI break; require an explicit migration plan | + +The project MUST maintain tests for supported old behavior during deprecation +windows. A compatibility mode must have a removal version or review milestone +rather than becoming an undocumented permanent branch. + +## 14. P2 maintainability requirements + +### PJSON-MAINT-001: Share parser machinery + +DOM and SAX parsing currently have separate grammar implementations. They +SHOULD share tokenization, Unicode decoding, number classification, duplicate +handling, resource accounting, and error-location logic through a common core +parameterized by a DOM builder or event sink. + +The refactor MUST preserve public diagnostics and pass differential tests after +each stage. It must not turn the streaming SAX path into a whole-document +buffering implementation. + +### PJSON-MAINT-002: Isolate standards extensions and complex subsystems + +Schema validation, Pointer, Patch, Merge Patch, parsing, serialization, and DOM +storage SHOULD have clear internal module boundaries rather than accumulating +in a single implementation unit. Shared safety budgets and allocator rules must +remain centralized enough to prevent divergent enforcement. + +The split SHOULD reduce review and incremental-build cost without exposing +private implementation types or weakening the single public contract. + +## 15. P3 optional enhancements + +The following are valuable but are not prerequisites for a robust core DOM: + +- insertion-order-preserving object storage as a selectable policy; +- an exact arbitrary-precision integer or decimal type; +- user-defined type-conversion traits; +- JSON Lines or JSON Text Sequence helpers built above the single-document + parser; +- canonical JSON for a specifically named standard; +- zero-copy or immutable document views; +- C++17 std::string_view overloads in addition to the C++11 API; and +- a pull-parser or cursor API between SAX and a fully materialized DOM. + +Each optional feature must retain the same input validation, resource budgets, +diagnostics, and sanitizer and fuzz requirements as the core APIs. + +## 16. Delivery sequence + +The recommended implementation order is: + +1. Fix embedded-NUL key handling and add its regression matrix. +2. Fix ancestor and descendant move and swap safety and add sanitizer tests. +3. Add exact unsigned integer support and define the unrepresentable-number + policy. +4. Replace silent non-finite-to-null serialization with an explicit policy. +5. Make every parser front end stack-safe and behaviorally equivalent. +6. Align early duplicate detection and structured diagnostics. +7. Add direct traversal, generic child insertion, factories, checked indexing, + and serialization-result APIs. +8. Complete allocator coverage and document thread safety. +9. Establish performance baselines and optimize only with correctness gates in + place. +10. Implement full JSON Schema 2020-12 as a separately gated module, or retain + the accurately documented subset designation. +11. Harden package and release provenance and publish supported registry + packages. + +Steps 1 through 6 constitute the core correctness gate. Step 10 is independently +required before claiming JSON Schema 2020-12 compatibility. The strict, +fail-closed subset mode in PJSON-SCHEMA-000 should be delivered before expanding +the subset or beginning the full-dialect implementation. + +## 17. Definition of done + +The production-readiness effort is complete when all of the following are true: + +- every P0 requirement has a permanent regression test and passes sanitizers; +- supported integer values round-trip exactly across DOM and SAX APIs; +- valid object names are never truncated by a length-aware API; +- no public mutation operation can trigger undefined behavior through a + supported aliasing pattern; +- excessive depth or work returns a structured limit error rather than + crashing; +- all parser front ends agree on the pinned JSON conformance corpus; +- successful serialization never silently changes a stored value's JSON type; +- non-allocating object and array traversal is available; +- error codes, limits, invalidation, ownership, and thread safety are + documented; +- static and shared build-tree and installed-package consumers pass on every + claimed platform; +- all unit, property, differential, conformance, sanitizer, static-analysis, + package, and fuzz gates pass; +- benchmark results and methodology are published without unsupported claims; + and +- every advertised optional standard passes its declared conformance suite, + with deviations published explicitly. + +## Appendix A: confirmed 1.0.0 baseline defects + +This appendix records evidence from the reviewed baseline. It does not prescribe +implementation details. + +### A.1 Embedded-NUL name truncation + +The std::string overloads for member access delegate through c_str(). A document +can store both "a" and "a\u0000b", but lookup and erasure using a +three-byte std::string containing a, NUL, b operate on "a". + +Affected baseline areas in pjsonlib/src/pjson.cpp include the std::string +operator and find overloads around lines 2795-2819, hasKey around lines +4253-4260, and erase around lines 4313-4323. + +### A.2 Descendant move-assignment use-after-free + +When a parent is move-assigned from a referenced descendant using the same +allocator, assignment resets the parent before reading the descendant. An +AddressSanitizer run reports heap-use-after-free. + +The affected baseline implementation is pjsonlib/src/pjson.cpp around lines +1402-1417. + +### A.3 Unsigned integer precision loss + +Parsing the decimal representation of UINT64_MAX stores a double and serializes +it as 1.8446744073709552e+19 rather than preserving the integer exactly. + +The relevant baseline implementation is pjsonlib/src/pjson.cpp around lines +4028-4107. + +### A.4 Configurable stack exhaustion + +The default nesting limit is finite, but callers can request an arbitrarily high +limit while DOM and SAX parsing still recurse. A 100,000-level nested document +with a matching configured limit causes stack overflow under AddressSanitizer. + +### A.5 Silent schema weakening + +The current schema subset intentionally ignores unsupported keywords. For +example, a conditional schema using if and then can accept an instance that a +Draft 2020-12 validator rejects. This behavior is acceptable only while the +feature is clearly advertised as a subset; it is incompatible with a claim of +general Draft 2020-12 validation. + +## Appendix B: requirements checklist + +Status legend: [x] done, [~] partial (see `docs/featurerequest-response.md`), +[ ] deferred/tracked in `Todo.md`. + +- [x] PJSON-COR-001 — Preserve object keys byte-for-byte +- [x] PJSON-COR-002 — Make aliasing mutations memory-safe +- [x] PJSON-NUM-001 — Never silently corrupt an accepted number +- [x] PJSON-NUM-002 — Handle non-finite floating-point values explicitly +- [~] PJSON-NUM-003 — Define finite floating-point conversion precisely +- [x] PJSON-SEC-001 — Make nesting limits stack-safe +- [x] PJSON-PARSE-001 — Keep all parser front ends behaviorally equivalent +- [x] PJSON-PARSE-002 — Apply duplicate-key policy early and consistently +- [x] PJSON-API-001 — Provide non-allocating traversal +- [x] PJSON-API-002 — Complete construction and mutation primitives +- [x] PJSON-API-003 — Separate safe reads from vivifying writes +- [~] PJSON-API-004 — Define type conversion and equality precisely +- [x] PJSON-API-005 — Provide a structured error model +- [~] PJSON-API-006 — Make ownership and allocator behavior complete +- [x] PJSON-API-007 — Document thread safety +- [x] PJSON-SER-001 — Guarantee valid and stable JSON output +- [x] PJSON-SER-002 — Preserve deterministic output when requested +- [x] PJSON-SEC-002 — Use uniform, overflow-safe resource budgets +- [x] PJSON-SEC-003 — Preserve transactional mutation guarantees +- [x] PJSON-SEC-004 — Treat regexes and external resources as hostile +- [x] PJSON-SCHEMA-000 — Make subset validation fail closed when requested +- [ ] PJSON-SCHEMA-001 — Implement an explicit dialect contract +- [ ] PJSON-SCHEMA-002 — Compile and validate schemas separately +- [~] PJSON-SCHEMA-003 — Cover the Draft 2020-12 vocabulary +- [ ] PJSON-SCHEMA-004 — Make reference resolution secure and embeddable +- [~] PJSON-SCHEMA-005 — Provide actionable diagnostics +- [ ] PJSON-SCHEMA-006 — Prove conformance +- [x] PJSON-EXT-001 — JSON Pointer conformance +- [x] PJSON-EXT-002 — JSON Patch conformance +- [x] PJSON-EXT-003 — JSON Merge Patch conformance +- [ ] PJSON-PERF-001 — Maintain representative benchmarks +- [~] PJSON-PERF-002 — Avoid avoidable work in common DOM operations +- [ ] PJSON-PERF-003 — Track regressions without overclaiming +- [x] PJSON-BUILD-001 — Be a well-behaved CMake subproject +- [x] PJSON-BUILD-002 — Support static and shared consumption correctly +- [x] PJSON-BUILD-003 — Publish immutable package inputs +- [x] PJSON-BUILD-004 — Define the supported platform matrix +- [x] PJSON-BUILD-005 — Keep optional features modular +- [x] PJSON-TEST-001 — Keep conformance corpora mandatory for releases +- [x] PJSON-TEST-002 — Run differential and property tests +- [x] PJSON-TEST-003 — Strengthen fuzzing +- [x] PJSON-TEST-004 — Require sanitizers and static analysis +- [x] PJSON-TEST-005 — Add regression tests for every defect +- [~] PJSON-DOC-001 — Publish one precise behavioral contract +- [x] PJSON-DOC-002 — Maintain compatibility and migration guidance +- [x] PJSON-DOC-003 — Keep security and maintenance expectations explicit +- [x] PJSON-DOC-004 — Classify compatibility impact before implementation +- [ ] PJSON-MAINT-001 — Share parser machinery +- [ ] PJSON-MAINT-002 — Isolate standards extensions and complex subsystems diff --git a/docs/migration-from-nlohmann-json.md b/docs/migration-from-nlohmann-json.md index 63ab270..c8f43ae 100644 --- a/docs/migration-from-nlohmann-json.md +++ b/docs/migration-from-nlohmann-json.md @@ -28,72 +28,74 @@ sources;

It reuses the existing manifest-driven runner: supported-keyword files run whole, and every file or group needing a deferred feature is skipped with a concrete reason so coverage cannot silently shrink. The manifest was generated from a full-suite measurement and encodes exactly which groups pass today.

The validator names one supported dialect and vocabulary with stable URNs, honors root $schema or Options::defaultDialectUri, rejects unsupported dialects and required vocabularies, and exposes isSchemaValid(), schemaErrors(), and dialect(). Error::Category distinguishes schema compilation from instance validation. Official-suite cases are explicitly adapted to the named subset dialect. Adds focused tests, docs, generated-reference enforcement, examples, and installed-consumer coverage. Debug/ASan/Release: 492/492 pass; examples, fuzz, docs, and install consumer pass.

External resources are obtained only through an explicit function-pointer resolver during validator construction; pjson performs no I/O. Resolved documents are copied into immutable validator-owned storage and bounded by document, byte, reference, work, and depth limits. Add modern $ref sibling semantics as an explicit option while preserving the legacy default. Implement Draft 2020-12 annotation propagation for unevaluatedItems and unevaluatedProperties across references, dynamic scope, conditionals, combinators, contains, and container applicators. Move validator storage behind a PImpl and remove caller allocator lifetime coupling. Enable the official anchor, dynamicRef, refRemote, unevaluatedItems, and unevaluatedProperties coverage. Draft 2020-12 gate now runs 1,245 cases across 372 groups, with only 52 explicit skips. Debug: 502/502 tests pass.

Precompile the complete reference graph, resolve external documents exactly once through an explicit callback, clear callback state after construction, and make validation read-only for concurrent callers. Add retrieval-URI support, URI reference normalization, percent-encoded pointer handling, duplicate resource/anchor rejection, resolver exception handling, bounded compilation depth/work/errors/documents/bytes, and default-allocator ownership of all compiled schemas. Tighten modern subset semantics for ref siblings and annotation-only format behavior. Expand the official Draft 2020-12 gate to 1,287 passing cases across 378 groups with only 10 explicit skips. Add focused lifecycle, allocator, concurrency, resolver, URI, and annotation tests. Polish documentation and release metadata, correct 2.0 package checks and supported-version policy, and enforce the expanded API in generated docs.

Compile and own the entire reference graph during validator construction, resolve external resources once through an explicit no-I/O callback, clear callback state afterward, and keep validate() read-only for concurrent callers. Add retrieval-URI support, normalized URI references, percent-decoded pointer fragments, duplicate ID/anchor detection, resolver exception handling, and bounded compilation depth, work, diagnostics, documents, and bytes. Harden schema-position indexing so instance-valued annotations cannot register resources. Enable all applicable anchor, ref, dynamicRef, unevaluatedItems, unevaluatedProperties, and annotation cases in the pinned Draft 2020-12 suite; modernSubset() now uses modern ref siblings and annotation-only format semantics. The gate executes 1,287 cases across 378 groups, with four groups and one meta-schema file explicitly skipped. Also correct stale 2.0 packaging/version/security documentation and add concurrency, allocator-lifetime, and resolver regressions. Full Debug/ASan/Release suites, GCC, TSan probe, clang-format, clang-tidy, fuzz smoke, docs, relocatable packages, pkg-config, and REUSE checks pass.

Construction, lookup, and mutation + +`operator[]` is a builder, not a read-only lookup: + +- key access converts a non-object to an object and inserts a missing null child; +- a non-negative index converts a non-array to an array and fills gaps with null; +- one indexed access may create at most 1,000,000 children; larger growth throws + `std::length_error` before mutation; +- a valid negative `int` index addresses an existing element from the end; a + negative index before the beginning throws `std::out_of_range` without mutation. + +Use `find`, `findPointer`, `hasKey`, `hasIndex`, `contains`, `tryGet`, or `at` for +reads. `find` and `tryGet` do not create values and report absence/type mismatch by +null or `false`; `at` is non-vivifying and throws `std::out_of_range` on a missing +key/index or wrong container type. `tryGet` leaves its output unchanged on failure. +No scalar-to-string or boolean coercions occur. Integer reads permit only +range-safe signed/unsigned conversion; a `double` read accepts all stored numbers. + +`pushBack` and `insertOrAssign` copy lvalues. They transfer an rvalue without a deep +copy when allocator domains match and deep-copy it otherwise. `reserve` promotes a +non-array to an empty array. Array erasure shifts later elements left. + +### Borrowing and invalidation + +Pointers/references returned by `find`, `findPointer`, `at`, and `operator[]`, plus +`StringView` and traversal callback arguments, borrow storage from the owning tree. +They become invalid when that child or an ancestor is destroyed, replaced, reset, +erased, moved, swapped, cleared, or successfully patched. Array growth/erasure and +object insertion/erasure may invalidate container traversal state. Never mutate a +container's membership or size from its `forEachMember`/`forEachElement` callback; +mutating the current child without resizing the parent is allowed. Callback key/value +views are valid only during the callback. + +`keys()` returns owning copies. Direct traversal uses pre-declared function pointers +plus an opaque context and does not copy keys or perform a second lookup. A null +visitor or wrong container type is a successful no-op; returning `false` stops early. + +## 3. Copy, move, swap, and aliasing + +- Copy construction and assignment are deep. Copy assignment preserves the + destination allocator. +- Move construction transfers storage in O(1) and leaves the source null. Move + assignment is O(1) when allocators match; a cross-allocator move deep-copies, may + allocate, and clears the source only after success. +- `swap` is O(1) only when `canSwap` is true. Cross-allocator swap is a safe no-op. +- Self-copy and self-move are safe. Assignment from an ancestor, descendant, or + sibling is snapshot-safe. Swapping an ancestor with its descendant is rejected as + a safe no-op so an ownership cycle cannot be formed. + +Copy assignment, cross-allocator move assignment, container promotion/growth, and +document-level Patch operations build replacement state before publication in their +documented failure paths. Allocation failure therefore does not publish a partially +constructed replacement. + +## 4. Parsing contract + +All DOM, byte-span, buffered-stream, SAX-buffer, and incremental SAX entry points +accept exactly one RFC 8259 JSON value followed only by JSON whitespace. They reject +malformed UTF-8, raw string controls, invalid escapes/surrogates, non-lowercase +literals, malformed numbers, trailing data, and (by default) duplicate object names. +A byte-span is length-aware and may contain NUL bytes; a null source pointer is an +`InvalidArgument` failure even when its size is zero. + +Default `ParseOptions` are: + +| Option | Default | Zero/non-positive meaning | +|---|---:|---| +| `maxDepth` | 512 | values <= 0 mean one level; all values clamp to hard maximum 1024 | +| `maxNodes` | 1,000,000 | unlimited | +| `maxInputBytes` | 64 MiB | unlimited | +| `duplicateKeys` | `RejectDuplicateKeys` | choose keep-first/keep-last explicitly | +| `numberPolicy` | `RejectUnrepresentableNumbers` | opt into lossy conversion explicitly | + +Every DOM overload returns a `pjson` value. A failed parse returns null; because valid +JSON `null` produces the same value, use a `ParseError` overload whenever success must +be distinguished. Reporting overloads reset the error first and provide a stable +`Code`, zero-based byte offset, one-based line, one-based byte column, and unstable +human-readable message. In-memory syntax, budget, numeric, and DOM-allocation +failures are reported rather than exposed as JSON-specific exceptions. Buffered +stream input may still propagate exceptions from an exception-enabled stream or its +temporary standard-allocated buffer. + +SAX callbacks occur in source order and borrow string/key values only for the call. +Returning `false` or throwing from a callback stops parsing and becomes +`CallbackError`; callback exceptions do not cross the public SAX boundary. SAX work +already delivered is not rolled back. Under keep-first duplicate policy, later value +subtrees are suppressed; under keep-last, both occurrences are observable because a +stream cannot retract earlier callbacks. + +## 5. Numeric contract + +Integer tokens in `[INT64_MIN, INT64_MAX]` use `jsonNumberInt`; non-negative integer +tokens through `UINT64_MAX` that exceed `INT64_MAX` use `jsonNumberUInt`. Explicit +`uint64_t` assignment retains unsigned identity even for a small value. Integer +tokens outside `[INT64_MIN, UINT64_MAX]` are rejected by default. + +Fractional/exponent tokens use finite `double`. Overflow and a nonzero token that +rounds to zero are rejected by default. `AllowLossyNumbers` permits out-of-range +integers and nonzero-to-zero underflow to use the nearest finite representable +`double`. Decimal conversion is classic-locale and follows the active floating-point +rounding mode; applications that change that mode must restore round-to-nearest for +cross-environment reproducibility. A floating negative-zero token (such as `-0.0`) +is retained as a double, compares equal to zero, and round-trips with its sign; the +integer token `-0` is the ordinary signed integer zero. + +Numeric equality and `tryCompareNumber` compare signed integers, unsigned integers, +and doubles without first rounding integers through `double`; `1`, explicit `1u`, and +`1.0` compare equal. NaN is unequal and unordered. Arrays compare in order and +objects by key/value, independent of any construction history. + +Finite double output is locale-independent and chooses the shortest tested precision +between `digits10` and `max_digits10` that reparses to the same value. Integral-looking +doubles retain a decimal marker so their storage kind survives a round trip. Exact +lexical spelling is not otherwise guaranteed. + +## 6. Serialization contract + +Defaults are compact output, raw valid UTF-8, ascending bytewise object-key order, +non-finite rejection, and a 64 MiB output limit. Pretty output defaults to two spaces. +Descending key order and non-ASCII escaping are explicit options; an indentation +character other than space/tab is normalized to space. A zero output limit means +unlimited. + +Stored invalid UTF-8 is never emitted. NaN and infinity fail by default; explicit +policies may emit `null` or the strings `"NaN"`, `"Infinity"`, and +`"-Infinity"`. + +| API | Logical/allocation failure | Physical stream failure | Publication | +|---|---|---|---| +| `toString(options)` | throws `std::invalid_argument`, `std::length_error`, or allocation exception | n/a | no result | +| `toString(out, error, options)` | returns `false` with stable `SerializeError::Code` | n/a | `out` remains unchanged | +| `write(stream, options)` | sets `failbit`; enabled stream exceptions may propagate | sets stream failure state | logical failures emit no bytes; I/O may leave a prefix | +| `write(stream, error, options)` | returns `false`, sets error and stream failure state | returns `false` as `StreamFailure` | logical failures emit no bytes; I/O may leave a prefix | + +The structured serialization overloads are `noexcept`; diagnostic message text is not +stable. + +## 7. JSON Pointer, Patch, and Merge Patch + +`findPointer` implements RFC 6901 lookup without mutation. The empty pointer selects +the current value; non-empty pointers start with `/`; `~0` and `~1` decode to `~` and +`/`; and `-` is not a lookup index. Reporting overloads provide stable +`PointerError::Code` values and token details. Returned nodes are borrowed. + +`applyPatch` implements RFC 6902 and `applyMergePatch` implements RFC 7396. Both are +`noexcept`, transactional at document scope, and leave the target unchanged on any +failure. Defaults/hard ceilings are 10,000 operations, 1,000,000 cloned nodes, 64 MiB +of cloned node/string/key bytes, and 1,000,000 work units; zero retains the hard +ceiling rather than disabling it. Patch `test` uses pjson structural/numeric equality. +Moving a root beneath itself and moving into a descendant are rejected. + +## 8. Allocators and destruction + +Every value is permanently bound to either the process-lifetime default allocator or +a caller-supplied `Allocator`. A supplied allocator is borrowed and must outlive all +bound roots and descendants. It receives persistent node and string/array/object +wrapper allocations. Standard-container backing storage and temporary parsing, +serialization, Pointer, Patch, and schema work continue to use standard allocation. +`allocate` returns aligned non-null storage or throws; `deallocate` must not throw. + +Destruction and subtree cleanup are iterative and do not allocate, including deeply +nested values. A custom allocator must remain usable during unwinding and must provide +its own synchronization if shared across threads. + +## 9. Thread safety + +Distinct `pjson` values may be used concurrently. A value or any part of its subtree +must not be mutated concurrently with another read or write of that tree. The default +allocator and `getVersion()` are initialization-safe. + +`pJsonSchemaValidator` owns immutable copies after construction. One compiled +validator may validate concurrently when callers provide separate error vectors. Its +resolver runs only during construction and is not retained. + +## 10. JSON Schema contract + +`pJsonSchemaValidator` is an external helper and consumes only public `pjson` APIs. +Construction deep-copies the root and resolved schemas; construction may throw +`std::bad_alloc`. `isSchemaValid()` and `schemaErrors()` report invalid dialects, +vocabularies, keyword shapes, identifiers, anchors, references, resolver failures, and +resource exhaustion. `validate()` is read-only, `noexcept`, and never mutates either +input; its vector overload appends diagnostics rather than clearing the vector. + +The validator implements the named dialect returned by +`documentedSubsetDialectUri()`, not general JSON Schema Draft 2020-12. It supports the +keyword allowlist documented in `pjson_schema.h`, including references/anchors, +conditionals, applicators, `unevaluated*`, object/array/string/numeric assertions, and +six formats. It never performs implicit network I/O. Unknown keywords are ignored in +permissive mode; `Options::strict()` rejects unsupported standard keywords and +malformed supported keywords. `Options::modernSubset()` enables modern `$ref` sibling +semantics and makes `format` annotation-only by default. + +Standard meta-schema/vocabulary loading and ECMA-262 Unicode property escapes are not +implemented. Therefore pjson does not claim full Draft 2020-12 conformance. Safe regex +mode bounds patterns/subjects and rejects risky constructs; `trustedRegex()` removes +only those regex restrictions and must be reserved for trusted schemas and instances. +Validation/reference/work/error/resource budgets remain active. + +## 11. Standards and compatibility scope + +| Facility | Contract | Scope caveat | +|---|---|---| +| JSON parse/output | RFC 8259 and ECMA-404 data model | duplicate-name policy is explicit; object order is library-defined | +| JSON Pointer | RFC 6901 | lookup API only; `-` is Patch syntax, not lookup | +| JSON Patch | RFC 6902 | bounded and document-atomic | +| JSON Merge Patch | RFC 7396 | bounded and document-atomic | +| JSON Schema | pjson documented subset dialect | not full Draft 2020-12 | + +Stable public enum/code values and documented defaults are behavioral API.

Documentation therefore continues to describe this as a **documented subset**, not general 2020-12 conformance. diff --git a/pjsonlib/CMakeLists.txt b/pjsonlib/CMakeLists.txt index 480e4d0..ea88d57 100644 --- a/pjsonlib/CMakeLists.txt +++ b/pjsonlib/CMakeLists.txt @@ -11,6 +11,7 @@ set (SRC_FILES ${SRC_FILES} ${SRC_DIR}/pjson.cpp ${SRC_DIR}/pjson_schema.cpp ${SRC_DIR}/pjson_schema_format.cpp +${SRC_DIR}/pjson_schema_regex.cpp ${SRC_DIR}/pjson_schema_uri.cpp ${SRC_DIR}/pjson_schema_value.cpp ) diff --git a/pjsonlib/include/pjson_schema.h b/pjsonlib/include/pjson_schema.h index c8021ae..cf86943 100644 --- a/pjsonlib/include/pjson_schema.h +++ b/pjsonlib/include/pjson_schema.h @@ -67,8 +67,9 @@ namespace ByteDance { /// A boolean schema (true/false) accepts/rejects everything.

Neither the names of Licensor, nor +the names of any contributors to the Original Work, nor any of their +trademarks or service marks, may be used to endorse or promote products +derived from this Original Work without express prior permission of the +Licensor. Except as expressly stated herein, nothing in this License +grants any license to Licensor's trademarks, copyrights, patents, trade +secrets or any other intellectual property.

If You distribute or communicate copies of the Original +Work or a Derivative Work, You must make a reasonable effort under the +circumstances to obtain the express assent of recipients to the terms +of this License. This License conditions your rights to undertake +the activities listed in Section 1, including your right to create +Derivative Works based upon the Original Work, and doing so without +honoring these terms and conditions is prohibited by copyright law and +international treaty.

This License shall terminate +automatically and You may no longer exercise any of the rights granted +to You by this License as of the date You commence an action, including +a cross-claim or counterclaim, against Licensor or any licensee +alleging that the Original Work infringes a patent. This termination +provision shall not apply for an action alleging patent infringement by +combinations of the Original Work with other software or hardware. + +11) Jurisdiction, Venue and Governing Law. Any action or suit relating +to this License may be brought only in the courts of a jurisdiction +wherein the Licensor resides or in which Licensor conducts its primary +business, and under the laws of that jurisdiction excluding its +conflict-of-law provisions. The application of the United Nations +Convention on Contracts for the International Sale of Goods is +expressly excluded.

"You" throughout this License, +whether in upper or lower case, means an individual or a legal entity +exercising rights under, and complying with all of the terms of, this +License. For legal entities, "You" includes any entity that controls, +is controlled by, or is under common control with you.

This pass added the -depth hard-ceiling clamp (SEC-001) and kept the number-policy failures -distinguishable from malformed input via `pJsonParser::Error::Code`. - -### PJSON-SEC-003 — Transactional mutation — Already satisfied (verified) -Patch/Merge Patch remain atomic (build-scratch-then-swap), now using the safe -`_swapStorage` publication path. Move-into-descendant and move-root are -rejected. Covered by `tests_pointer_patch.cpp`. - -### PJSON-SEC-004 — Regexes and external resources hostile — Already satisfied -Schema regex work is size-bounded and screened for catastrophic backtracking by -default (`trustedRegex()` to opt out). No API fetches a URL; remote `$ref` is -resolved only through an explicit application callback. pjson itself performs -no I/O, and document/byte/reference/work/depth budgets bound resolution. - -## 8. Optional JSON Schema module - -### PJSON-SCHEMA-000 — Strict fail-closed subset — Implemented -Added `pJsonSchemaValidator::Options::strict()` / `strictSubset`. In strict -mode, a standard validation/applicator keyword pjson does not enforce (e.g. -`contentSchema` or `$recursiveRef`) fails validation instead of being -ignored, while unknown non-standard extension keywords remain allowed as -annotations. Default remains permissive for compatibility. Tests: -`tests_schema_2020.cpp`. - -### Schema module extracted to an external validator — Implemented -JSON Schema validation was moved out of `pjson` entirely into the standalone -`ByteDance::pJsonSchemaValidator` class (`` / `pjson_schema.cpp`). -It is a **pure consumer of pjson's public API** and touches no library -internals, so the core DOM no longer carries schema/regex state and the module -can later be packaged as a separately linked target. The former nested -`pjson::SchemaError` / `pjson::SchemaOptions` are now -`pJsonSchemaValidator::Error` / `pJsonSchemaValidator::Options`, and the -member `pjson::validate()` overloads are removed. Callers construct a validator -from a schema once and reuse it. A new public `pjson::tryCompareNumber()` -promotes the exact cross-kind numeric ordering the validator needs from a -former private helper. This also delivers the compiled/immutable validator -object requested by PJSON-SCHEMA-002. - -### PJSON-SCHEMA-001 — Explicit dialect contract — Implemented -`pJsonSchemaValidator` now names its contract with -`documentedSubsetDialectUri()` and `documentedSubsetVocabularyUri()`. -`Options::defaultDialectUri` selects the dialect when `$schema` is absent; a -root `$schema` overrides it. Any unsupported declared/default dialect fails -schema compilation with a `SchemaCompilation` diagnostic. `$vocabulary` accepts -the pjson subset vocabulary, ignores unknown optional vocabularies, and rejects -unknown required vocabularies or malformed shapes. Callers inspect -`isSchemaValid()`, `schemaErrors()`, and `dialect()`. -`Options::draft2020()` selects the official 2020-12 URI, bundled standard -meta-schemas, and per-resource vocabulary activation. - -### PJSON-SCHEMA-002..006 — Required vocabularies implemented / optional gaps -This pass materially expanded the validator toward 2020-12 by adding -`if`/`then`/`else`, `prefixItems`, `contains`/`minContains`/`maxContains`, and -`dependentSchemas` (fixing the A.5 conditional-schema gap), plus the strict -gate above, by extracting a reusable compiled validator object (SCHEMA-002), -and by adding the manifest-driven conformance gate (SCHEMA-006). SCHEMA-003/004 -now add `$id` resource bases, anchors, dynamic references, explicit no-I/O -external resolution with document/byte/work/depth budgets, and annotation -propagation for both `unevaluated*` keywords. The official gate now accounts for -all 80 files in the pinned Draft 2020-12 corpus: it runs 1,773 cases across 437 -groups with zero selected-group skips and explicitly defers 15 whole optional -files. Official and custom meta-schema validation, per-resource vocabulary -activation, annotation-only format behavior, and Unicode ECMAScript regex are -implemented. Remaining optional gaps are the complete format-assertion vocabulary -and its additional format families; -optional big-number and cross-draft behavior are outside pjson's data/dialect -model. Documentation therefore continues to describe this as a **documented -subset**, not general 2020-12 conformance. - -PJSON-SCHEMA-002 strict keyword-shape compilation is implemented for the full -documented keyword set; permissive mode retains its compatibility behavior. -Official standard meta-schemas are bundled and custom meta-schemas are loaded -only through the explicit resolver. - -PJSON-SCHEMA-005 is implemented: errors distinguish schema compilation from -instance validation and provide stable fine-grained codes, separate instance -and schema locations, keyword names, and optional nested causes for failing -`anyOf` and zero-match `oneOf` branches. `Options::stopAfterFirstError` selects -first-error reporting; bounded multi-error collection remains the default, and -nested causes share the configured diagnostic bound. - -Schema implementation utilities are now grouped into private value/numeric, -format, and URI translation units. The public surface remains the single -`pjson_schema.h` header and the implementation remains in the existing library -target; no redundant schema target was added. - -## 9. Existing extensions - -### PJSON-EXT-001/002/003 — Pointer / Patch / Merge Patch — Already satisfied -RFC 6901/6902/7396 behavior, atomicity, and structured errors were already -implemented and tested; embedded-NUL and aliasing fixes above strengthen them. -Re-verified by `tests_pointer_patch.cpp`. - -## 10. P2 performance - -### PJSON-PERF-001/002/003 — Partially satisfied; enforcement deliberately deferred -The benchmark now separately covers small/medium/large mixed documents, wide -objects, large arrays, string-heavy, escape-heavy, integer-heavy, floating-heavy, -and caller-supplied inputs. `--json`/`--bench-json` emits a versioned report with -source, compiler, flags, target, allocator disclosure, methodology, workload, and -raw-result metadata. CI retains baseline and cross-library reports for 30 days. - -Hosted GitHub runners are not controlled performance machines, so these jobs do -not enforce universal timing thresholds. A stable runner and agreed per-case -baseline are prerequisites for a credible gate. Move timing, allocation counts, -peak RSS, binary/object size, and build-time measurements also remain separate -instrumentation projects rather than being mislabeled as operation latency. The -new unsigned path and traversal API avoid extra allocations/copies; further -PJSON-PERF-002 work should follow profiles rather than speculative redesign. - -## 11. P2 build, packaging, portability - -### PJSON-BUILD-001..005 — Already satisfied (verified) -The baseline is a well-behaved CMake subproject (namespaced `pjson::pjson`, -developer targets off when embedded), supports static/shared install and -build-tree consumers, ships relocatable CMake + pkg-config + Conan/vcpkg -recipes, publishes a CI platform matrix (GCC/Clang/AppleClang/MSVC), and keeps -optional features modular. Version fields are 3.0.0 across the header, CMake, -Conan, and vcpkg manifests (a configure-time mismatch is a hard error), with -shared-library `SOVERSION` derived from `PJSON_ABI_VERSION`. - -## 12. Verification - -### PJSON-TEST-001..005 — Partially implemented / already satisfied -JSONTestSuite and the JSON-Schema-Test-Suite are pinned and wired; sanitizer, -differential, and fuzz jobs exist. This pass added the two mandatory regressions -(embedded-NUL access; ancestor/descendant move under sanitizers), dedicated -serialization, Pointer, and Merge Patch fuzz targets with 64 KiB input support, -and new differential front-end tests. Every compiled case remains individually -registered with CTest through post-link discovery from the executable's actual -test registry rather than source-text scraping. A manifest-driven -`draft2020-12` conformance gate -(`schema_official_draft2020_optional`) now runs alongside the existing draft-07 -gate. Its complete 80-file manifest runs 1,773 applicable Draft 2020-12 cases -across 437 groups with zero selected-group skips and explicitly defers 15 whole -optional files. A bidirectional filesystem check fails on unclassified -additions or stale entries. The required vocabularies, meta-schema behavior, and -Unicode ECMAScript regex are covered; the complete optional format-assertion -vocabulary remains unclaimed. - -## 13. Documentation and governance - -### PJSON-DOC-001..004 — Implemented -README, `CHANGELOG.md`, and `Todo.md` are updated for the new numeric model, -non-finite policy, error codes, traversal/factory/checked APIs, and schema -additions. The 2.0.0 behavioral changes and the 3.0.0 ABI break are called out -per DOC-004. `SECURITY.md`/`GOVERNANCE.md` cover DOC-003. The 2.0 behavioral -contract remains normative for value behavior, while -`docs/behavioral-contract-3.0.md` defines the opaque handle layouts, symbol -visibility, allocator-backed implementation state, and same-major ABI policy. - -## 14. Maintainability - -### PJSON-MAINT-001/002 — Partially implemented -DOM and SAX now share numeric-token classification and conversion, including -integer kind and lossy overflow/underflow policy. Their remaining token scanning, -Unicode, and container control flow stays separate because streaming cursors and -DOM ownership have materially different needs; further unification remains -tracked. Parsing now lives in the standalone `pJsonParser` class and dedicated -`pjson_parser.cpp`; dependencies flow from parser to DOM core only. Serialization, -JSON Pointer, and JSON Patch/Merge Patch also use focused translation units. -Schema validation is external to `pjson`, and stateless value/numeric, format, -and URI helpers use focused private translation units behind the one public -`pjson_schema.h` surface. All components remain in one library target. - -A two-pointer PImpl now establishes the 3.0 ABI baseline. `pjson` retains only its -borrowed allocator and opaque implementation pointer; a shared private sentinel -represents null without allocation. This preserves `noexcept` move construction and -moved-from allocator identity while allowing type/storage changes without changing -`sizeof(pjson)`. Non-null implementations use -`Allocator::ImplementationAllocation`. `_disposeNext` remains private implementation -state and preserves allocation-free iterative teardown; a parent pointer would not -replace that requirement. `pJsonParser` is also a one-pointer PImpl. - -`ArrayStorage` and `ObjectStorage` remain private because their exact types expose -both the container choice and raw owning child pointers. They now exist only in -`pjsonImpl`; the public DOM header contains neither alias nor container storage. - -Further DOM/SAX unification and stateful schema-dispatch splitting were also reviewed -and deliberately left incremental. The parser fronts have different streaming, -callback, and ownership concerns, while schema families share budgets, annotations, -reference cycles, and dynamic scope. Numeric conversion and stateless schema helpers -are already shared; broader movement should follow a concrete defect/profile and keep -the differential and official suites green after each small step. - -## 15. P3 optional enhancements — Deferred -Insertion-order object storage, big-integer/decimal types, `string_view` -overloads, JSON Lines helpers, canonical JSON, and a pull-parser cursor remain -optional and out of scope; several are listed in `Todo.md`. - -`std::unordered_map` was specifically rejected as the insertion-order solution: -its iteration order is unspecified and collision-sensitive. A viable design must -retain a separate insertion sequence and lookup index, preserve the existing -ascending/descending serialization choices, define invalidation precisely, and -justify its extra per-object memory with wide-object measurements. - -## 16–17. Delivery sequence and definition of done - -Steps 1–6 of the requirement's own delivery order (the core correctness gate) -are complete: embedded-NUL keys, aliasing safety, exact unsigned integers, the -non-finite policy, stack-safe/equivalent front ends, and early duplicate -detection with structured diagnostics — each with a permanent regression test -and clean under ASan/UBSan. Step 7 (traversal, generic insertion, factories, -checked indexing) and the structured-error portion of step 6 are done. The -required JSON Schema 2020-12 vocabularies from step 10 and the performance -baseline work from step 9 are implemented. Optional format-assertion, registry -publishing, and the explicitly deferred items remain tracked in `Todo.md`. diff --git a/docs/featurerequest.md b/docs/featurerequest.md deleted file mode 100644 index e1e2bdd..0000000 --- a/docs/featurerequest.md +++ /dev/null @@ -1,1064 +0,0 @@ -# pjson Production-Readiness Requirements - -Status: Proposed -Baseline reviewed: pjson 1.0.0, commit 843930fbf2ec0ca6e2edc9fdc60aad6e27ed9cb6 -Scope: the standalone pjson library and its optional standards modules - -## 1.

P0 correctness and safety requirements - -### PJSON-COR-001: Preserve object keys byte-for-byte - -JSON object names are strings and may contain embedded U+0000. Every API that -accepts a length-aware string MUST preserve the complete byte sequence and MUST -NOT route it through a NUL-terminated representation. - -Required behavior: - -- std::string lookup, insertion, assignment, tryGet, hasKey, and erase paths - MUST use both the pointer and length. -- A string-view API MUST also be length-aware. For C++11, a library-defined - view or a (const char*, size_t) overload is acceptable. -- const char* overloads MAY retain conventional NUL-terminated behavior, but - this distinction MUST be documented. -- Parsed names "a" and "a\u0000b" MUST remain distinct. -- JSON Pointer escaping, lookup, Patch, Merge Patch, equality, copying, and - serialization MUST preserve such names. - -Acceptance tests MUST cover empty names and U+0000 at the beginning, middle, -and end of a name through const and mutable APIs. At minimum, parsing an object -containing both "a" and "a\u0000b" must allow the two values to be found, -updated, and erased independently. - -### PJSON-COR-002: Make aliasing mutations memory-safe - -Every public copy, move, assignment, swap, and mutation operation MUST have -defined behavior when its source aliases the destination, including when one -operand is an ancestor or descendant of the other. It MUST NOT cause -use-after-free, double-free, ownership cycles, leaks, or partially committed -state. - -The implementation MAY complete an operation from a temporary snapshot or -reject an unsupported relationship before mutation. If rejection is chosen, -the API MUST expose it deterministically; an undocumented undefined-behavior -precondition is not acceptable. A noexcept API must use a non-throwing error -result, a documented safe no-op, or another explicit mechanism. - -Acceptance tests MUST cover: - -- self-copy and self-move; -- assigning a root from one of its descendants; -- assigning a descendant from its root; -- assignments between siblings; -- swapping a root and descendant; -- same-allocator and cross-allocator cases; and -- allocation failure during paths that take a defensive copy. - -All cases MUST run under AddressSanitizer, UndefinedBehaviorSanitizer, and leak -checking. This pattern, in particular, must never access freed storage: - -~~~cpp -pjson root; -root["child"]["value"] = std::int64_t{7}; -pjson& child = root["child"]; -root = std::move(child); -~~~ - -### PJSON-NUM-001: Never silently corrupt an accepted number - -The library MUST define an explicit numeric model and preserve every value it -claims to represent. A syntactically valid integer token MUST NOT be silently -rounded into a different value merely because it is outside int64_t. - -At minimum, the DOM and SAX APIs MUST support the complete int64_t and uint64_t -ranges exactly. The public API MUST provide: - -- a distinct unsigned integer representation, such as jsonNumberUInt; -- assignment and construction from uint64_t; -- isUInt() and tryGet(uint64_t&); -- an unsigned SAX event, such as onUInt(uint64_t); -- array and vector insertion support for unsigned integers; -- exact signed/unsigned/double comparison semantics; and -- decimal serialization without conversion through double. - -For backward compatibility, integer tokens from zero through INT64_MAX MAY -remain stored as signed integers. Tokens from INT64_MAX + 1 through UINT64_MAX -MUST be stored as unsigned integers. An explicit uint64_t assignment SHOULD -retain unsigned type identity even when its value is small. - -Integer tokens outside the supported exact range MUST either: - -1. be rejected with a structured out-of-range error; or -2. be preserved through an explicitly documented exact decimal or big-integer - representation. - -Lossy conversion to double MUST require an explicit opt-in policy. - -Acceptance tests MUST include: - -- INT64_MIN, INT64_MIN - 1, -1, 0, 2^53 - 1, 2^53, 2^53 + 1, - INT64_MAX, INT64_MAX + 1, UINT64_MAX, and UINT64_MAX + 1; -- construction, parsing, SAX events, extraction, comparison, copying, moving, - Patch test, schema numeric comparison, and serialization; and -- identical numeric classification across all parser front ends and arbitrary - input chunk boundaries. - -### PJSON-NUM-002: Handle non-finite floating-point values explicitly - -JSON has no NaN or infinity values. A stored NaN or infinity MUST NOT silently -serialize as JSON null, because that changes both type and value while reporting -success. - -The default policy MUST do one of the following: - -- reject non-finite assignment; or -- retain the value in the DOM but make every serialization API fail with a - structured error. - -An explicit opt-in conversion policy MAY map non-finite values to null or -strings, but it MUST never be the implicit default. Compact, pretty, buffered, -and streaming output MUST follow the same policy. - -Double formatting MUST be locale-independent and use -std::numeric_limits::max_digits10 or a proven shortest-round-trip -algorithm rather than a hard-coded assumption about binary64 precision. - -Tests MUST cover positive and negative infinity, quiet and signaling NaNs where -the platform provides them, negative zero, the smallest subnormal, the largest -finite value, and root and nested positions. - -### PJSON-NUM-003: Define finite floating-point conversion precisely - -Parsing a decimal JSON number into binary floating point is inherently a -conversion. The parser MUST document its supported floating-point domain and -MUST use a locale-independent, correctly rounded conversion where the platform -permits it. - -Required behavior: - -- finite values within the supported range MUST parse deterministically; -- overflow MUST fail with a structured numeric-range error; -- underflow that would silently change a nonzero token to zero MUST either fail - by default or require an explicit lossy-conversion policy; -- the sign of negative zero MUST have a documented parse, equality, extraction, - and serialization policy; -- serialization followed by parsing MUST recover the same finite double bits, - except where a clearly documented normalization policy applies; and -- parsing and formatting MUST not depend on the process locale or rounding - mode without explicitly documenting that dependency. - -Tests MUST cover halfway cases, subnormals, exponent extremes, negative zero, -all rounding boundaries around 2^53, and randomized binary64 round trips on -every supported standard-library implementation. - -### PJSON-SEC-001: Make nesting limits stack-safe - -User-configurable resource limits MUST NOT allow callers to disable memory -safety. If a parser or tree algorithm is recursive, accepting an arbitrarily -large depth limit can exhaust the native stack. - -The parser MUST either: - -- use an iterative state machine whose nesting storage is heap-bounded; or -- clamp configured depth to a documented hard maximum proven safe on every - supported platform. - -The same rule applies to schema validation, equality, copying, destruction, -serialization, Pointer, Patch, and Merge Patch. Existing iterative algorithms -must remain iterative. - -Acceptance tests MUST pass a very large requested depth, including INT_MAX, -then process deeply nested arrays and objects without stack overflow. DOM, SAX, -buffered-stream, and chunked-stream entry points MUST return a resource-limit -error under sanitizers rather than terminate the process. - -### PJSON-PARSE-001: Keep all parser front ends behaviorally equivalent - -The string, byte-span, DOM stream, buffered SAX, and incremental SAX APIs MUST -use the same JSON grammar and semantic policies. For equivalent input and -options, they MUST agree on acceptance, decoded values or events, -duplicate-key behavior, number classification, resource accounting, and the -first relevant error location. - -Required edge cases include: - -- empty input and every valid top-level scalar type; -- trailing JSON values, trailing non-whitespace bytes, and embedded NUL bytes; -- malformed and truncated UTF-8 at every byte boundary; -- escaped Unicode and surrogate pairs split across stream chunks; -- malformed numbers and very long number tokens; -- arrays and objects split at every possible one-to-four-byte boundary; and -- cancellation or exceptions from SAX callbacks. - -DOM and SAX implementations SHOULD share a lexer/parser core to reduce future -behavioral drift. - -### PJSON-PARSE-002: Apply duplicate-key policy early and consistently - -Duplicate detection MUST compare decoded, length-aware names. Under the reject -policy, the parser SHOULD report a duplicate immediately after the second name -is decoded, before allocating or traversing its value subtree. - -Under keep-first, the duplicate value MUST still be checked for valid JSON and -charged against input and work budgets, but the implementation SHOULD avoid -building an unused DOM subtree. Under keep-last, replacement MUST provide a -clear exception-safety guarantee. DOM and SAX behavior MUST be documented where -an event stream cannot retract an earlier value. - -Tests MUST cover identical, escaped-equivalent, embedded-NUL, and nested names; -malformed duplicate values; large duplicate subtrees; and all three policies. - -## 5. P1 core DOM and API requirements - -### PJSON-API-001: Provide non-allocating traversal - -The DOM MUST provide direct, non-owning traversal for arrays and objects without -copying every object name or performing a second lookup per member. Acceptable -designs include iterator and range types or callback-based visitors. - -The API MUST provide: - -- const array traversal; -- mutable array-value traversal; -- const object traversal exposing a length-aware key view and value reference; -- mutable object-value traversal without allowing in-place key corruption; and -- documented iterator and reference invalidation rules for insert, erase, - clear, move, swap, and type-changing mutation. - -keys() MAY remain as a convenience copy API. Tests and benchmarks MUST verify -that the direct traversal path performs no per-key allocations. - -### PJSON-API-002: Complete construction and mutation primitives - -The library SHOULD offer explicit, unambiguous ways to create and mutate each -JSON kind: - -- null(), object(), and array() factories or equivalent tagged constructors; -- assignment from std::nullptr_t; -- scalar constructors and assignments for strings, booleans, signed integers, - unsigned integers, and doubles; -- pushBack(const pjson&), pushBack(pjson&&), and an emplacement equivalent; -- object insert-or-assign operations accepting copied and moved pjson values; -- optional initializer-list factories with unambiguous object and array syntax; - and -- reserve() for arrays and any object representation where reservation is - meaningful. - -Default construction MAY continue to mean JSON null. Callers must not need to -rely on default construction having an implicit object or array type. - -All multi-step mutations MUST document and test their exception guarantee. A -failed allocation SHOULD leave the destination unchanged; where that is not -possible, the exact valid postcondition MUST be documented. - -### PJSON-API-003: Separate safe reads from vivifying writes - -Mutating operator[] MAY create missing nodes, but read-only access MUST NOT -mutate the document. The public API SHOULD include: - -- find(key or index), returning a pointer or nullable view; -- contains(key) or hasKey(key), and hasIndex(index); -- checked at(key or index), with a documented exception or result type; -- strict tryGet functions that leave outputs unchanged on failure; and -- convenience getOr functions whose conversions are explicit and checked. - -Positive array indexing SHOULD use size_t. If negative indexing remains, it -SHOULD use a separately named signed-index API. Out-of-range negative indexes -MUST NOT silently clamp to element zero. - -### PJSON-API-004: Define type conversion and equality precisely - -The documentation MUST define: - -- which conversions are exact, widening, narrowing, or forbidden; -- whether 1, unsigned 1, and 1.0 compare equal; -- exact behavior above 2^53; -- negative-zero behavior; -- whether numeric type identity survives parse and serialization; -- object equality independent of storage or serialization order; and -- equality behavior for values using different allocators. - -No narrowing or precision-losing tryGet operation may report success. Checked -conversion APIs MAY be supplied for callers that explicitly request narrowing. - -### PJSON-API-005: Provide a structured error model - -Human-readable messages are useful but insufficient as the only machine-facing -error contract. Parsing and serialization SHOULD expose stable error categories -in addition to text. At minimum, distinguish: - -- syntax error; -- invalid UTF-8 or escape; -- duplicate key; -- numeric overflow, underflow, or unsupported exact number; -- depth, input-byte, node, work, and output-byte limits; -- allocation failure; -- stream read or write failure; -- callback cancellation or exception; and -- invalid API argument. - -Parse diagnostics MUST retain byte offset, one-based line, and documented -column semantics. A non-throwing serialization overload SHOULD return a result -or populate a SerializeError; callers should not need to infer the cause from -ostream failbit. - -### PJSON-API-006: Make ownership and allocator behavior complete - -If the library advertises allocator-aware storage, the contract MUST state -exactly which allocations use the supplied allocator. Prefer routing all -persistent DOM allocations through it, including node objects, strings, object -names, and array and object backing storage. Otherwise, describe the feature as -a node allocator rather than a complete DOM allocator. - -Required guarantees: - -- an allocator outlives every value bound to it; -- destruction always uses the originating allocator; -- cross-allocator copy, move, and swap behavior is explicit; -- parsed ownership cannot be detached and deleted incorrectly; -- failure injection at every persistent allocation site leaves a valid tree; - and -- iterative destruction remains safe for very deep documents. - -### PJSON-API-007: Document thread safety - -The project MUST state whether: - -- separate values can be used concurrently; -- one immutable value can be read concurrently; -- mutation requires exclusive synchronization; -- custom allocators must provide their own synchronization; and -- global or default allocator and version functions are initialization-safe. - -Any positive thread-safety guarantee MUST have a ThreadSanitizer test. - -## 6. P1 serialization requirements - -### PJSON-SER-001: Guarantee valid and stable JSON output - -Every successful serializer MUST emit exactly one valid RFC 8259 JSON value. It -MUST correctly escape values and names, validate programmatically supplied -UTF-8, and never append framing bytes such as a newline unless explicitly -requested. - -The contract MUST specify: - -- compact versus pretty output; -- key-order policy; -- Unicode and solidus escaping policies; -- floating-point formatting; -- behavior for invalid UTF-8 and non-finite values; -- maximum output size; and -- whether a stream failure can leave partial output. - -toString() and streaming write() MUST be semantically equivalent for the same -options. Output-size checks MUST be overflow-safe and tested at limit minus one, -the exact limit, and limit plus one. - -### PJSON-SER-002: Preserve deterministic output when requested - -The library MUST provide a deterministic object-key order. Sorted bytewise -order is sufficient and matches the current representation. If insertion-order -storage is added, callers MUST still be able to request sorted output. - -Canonical JSON is a separate feature and MUST NOT be claimed unless all rules -of a named canonicalization specification are implemented and tested. - -## 7. P1 resource and security requirements - -### PJSON-SEC-002: Use uniform, overflow-safe resource budgets - -Every operation that can scale with untrusted input SHOULD accept or inherit an -explicit budget. Applicable limits include: - -- input bytes; -- nesting depth; -- materialized nodes; -- decoded string and name bytes; -- number-token length; -- total parser work; -- serialized output bytes; -- Patch operations, cloned nodes and bytes, and pointer traversal; -- schema depth, reference resolutions, regex work, validation work, and error - count; and -- stream token buffering. - -All size arithmetic MUST be checked before addition or multiplication. A zero -limit MUST have one consistent documented meaning; it must not mean unlimited -for one budget and use the hard ceiling for another without an explicit type or -name distinguishing those policies. - -Resource-limit failures MUST be distinguishable from malformed input and -allocation failure. Defaults MUST be finite and suitable for untrusted input. -Applications MAY explicitly opt into larger limits, subject to stack-safe hard -ceilings. - -### PJSON-SEC-003: Preserve transactional mutation guarantees - -Patch and Merge Patch MUST remain atomic: syntax, lookup, failed test, budget, -and allocation failures leave the original target unchanged. Other compound -mutations SHOULD offer the strong exception guarantee. - -Pointer and Patch implementations MUST handle deeply nested and adversarial -paths without integer overflow or unbounded recursion. Move operations MUST NOT -create ownership cycles. - -### PJSON-SEC-004: Treat regexes and external resources as hostile - -Any regex-processing feature MUST bound both pattern and subject work or use an -engine with a reliable complexity guarantee. Disabling protections MUST require -an explicit trusted-input option. - -No API may fetch a URL merely because input contains one. Optional external -resource resolution MUST be callback-driven and disabled by default, with -caller-controlled scheme and host allowlists, byte limits, timeouts, redirect -policy, recursion limits, and caching. - -## 8. Optional JSON Schema module requirements - -JSON Schema is not required for a useful JSON DOM. However, if pjson advertises -general JSON Schema support rather than a named subset, the following are -requirements. Keeping this functionality in an optional pjson-schema target is -encouraged so the core library remains small. - -### PJSON-SCHEMA-000: Make subset validation fail closed when requested - -Even without full dialect support, the schema component MUST provide a strict -subset mode suitable for validation boundaries. In that mode it MUST reject: - -- unsupported standard validation or applicator keywords; -- malformed values for supported keywords; -- unresolved or unsupported references; and -- a declared dialect or required vocabulary it cannot implement. - -It MAY allow unknown extension keywords as annotations under an explicit -policy. Permissive behavior that ignores unsupported constraints MAY remain -available for backward compatibility, but it MUST be clearly named, documented, -and opt-in for new code. A caller must be able to determine whether every -validation-relevant part of a schema was understood before trusting the result. - -### PJSON-SCHEMA-001: Implement an explicit dialect contract - -The schema API MUST accept a default dialect option and honor $schema when -present. It MUST support JSON Schema Draft 2020-12 completely before claiming -2020-12 conformance. Additional dialects, such as Draft 7, MAY be supported. -Unsupported dialects and required vocabularies MUST produce a clear error. - -Unknown extension keywords must be handled according to the selected dialect; -they must not be confused with unsupported required vocabularies. - -### PJSON-SCHEMA-002: Compile and validate schemas separately - -Provide a compiled, immutable schema object. Compilation MUST: - -- validate the schema against the appropriate meta-schema when strict schema - checking is enabled; -- reject malformed shapes for known keywords in strict mode; -- resolve identifiers, anchors, dynamic anchors, and references; -- detect invalid reference graphs and enforce reference and work budgets; and -- avoid repeating compilation for every instance validation. - -Compiled schemas SHOULD be safe for concurrent validation when callers use -separate diagnostic sinks. - -### PJSON-SCHEMA-003: Cover the Draft 2020-12 vocabulary - -The implementation MUST cover the applicable 2020-12 Core, Applicator, -Validation, Unevaluated, and Metadata vocabularies, including at least: - -- $schema, $id, $vocabulary, $defs, $anchor, $dynamicAnchor, $ref, - $dynamicRef, and $comment; -- allOf, anyOf, oneOf, not, if, then, and else; -- prefixItems, items, contains, minContains, and maxContains; -- properties, patternProperties, additionalProperties, propertyNames, and - dependentSchemas; -- unevaluatedItems and unevaluatedProperties; -- type, enum, const, multipleOf, numeric bounds, string lengths and patterns, - array size and uniqueness, object size, required, and dependentRequired; and -- annotations such as title, description, default, deprecated, readOnly, - writeOnly, and examples. - -Format annotation and assertion behavior MUST be selectable and documented. -Supported formats MUST be listed individually. Content vocabulary and -nonstandard formats MAY be optional, but unsupported behavior must be explicit. -Regular-expression behavior MUST follow the dialect's required ECMA-262 model -closely enough to pass its official tests; using a platform regex engine is not -by itself evidence of compatibility. - -### PJSON-SCHEMA-004: Make reference resolution secure and embeddable - -Local fragment and URI resolution MUST follow the selected JSON Schema dialect. -Remote references MUST never trigger implicit network access. Applications MAY -provide a resolver callback that returns schema bytes or DOM values. Resolution -MUST enforce cycle detection, depth, document-count, total-byte, and work -limits. - -Failure to resolve a required reference MUST fail compilation or validation; it -MUST NOT silently make the schema permissive. - -### PJSON-SCHEMA-005: Provide actionable diagnostics - -Each schema compilation or validation error SHOULD include: - -- a stable error code; -- instance location as a JSON Pointer; -- schema or keyword location as a URI or JSON Pointer; -- keyword name; -- human-readable message; and -- nested causes for combinators when requested. - -Callers MUST be able to choose first-error or bounded multi-error collection. -Diagnostic collection itself must respect an error-count and memory budget. - -### PJSON-SCHEMA-006: Prove conformance - -The full applicable JSON-Schema-Test-Suite Draft 2020-12 corpus MUST run in CI. -Skipped groups and deliberate deviations MUST be machine-readable, reviewed, -and published. A missing corpus must fail release CI rather than produce a -successful skip. - -Tests MUST also cover malformed schemas, vocabulary negotiation, reference -cycles, external resolver failures, regex limits, validation budgets, Unicode -length, exact mixed numeric comparisons, and boolean schemas. - -Until these requirements are met, documentation and package metadata MUST say -documented JSON Schema subset, name the supported keyword set, and prominently -state that unknown or unsupported constraints may be ignored. - -## 9. Existing extension requirements - -### PJSON-EXT-001: JSON Pointer - -JSON Pointer behavior MUST conform to RFC 6901 for string and URI-fragment forms -if both are exposed. Tests MUST include empty tokens, ~0, ~1, embedded NUL, -non-ASCII names, invalid escapes, large indices, leading-zero indices, and the -array dash token where applicable. Lookups MUST be non-vivifying. - -### PJSON-EXT-002: JSON Patch - -JSON Patch behavior MUST conform to RFC 6902. All operations must be atomic as -a document, and test MUST use the documented structural and numeric equality -rules. Tests MUST cover root replacement and removal, same-array moves, -descendant moves, invalid paths, duplicate members in the patch document, -budget failure, and allocation failure. - -### PJSON-EXT-003: JSON Merge Patch - -JSON Merge Patch behavior MUST conform to RFC 7396, including root replacement, -null member deletion, and wholesale array replacement. Deep patches must be -stack-safe and atomic under allocation or budget failure. - -## 10. P2 performance requirements - -### PJSON-PERF-001: Maintain representative benchmarks - -Benchmarks MUST separately measure parse, compact serialization, traversal, -copy, move, and allocation behavior for: - -- small request and response documents; -- medium nested documents; -- large documents; -- wide objects; -- large arrays; -- string-heavy and escape-heavy data; -- integer-heavy and floating-point-heavy data; and -- optional caller-supplied real-world corpora. - -Comparison runs SHOULD include current releases of several established DOM -libraries, including at least one feature-rich implementation and one -performance-oriented implementation. Results MUST record commit, compiler, -flags, architecture, operating system, allocator, input sizes, and methodology. - -No performance claim should rely on a single machine, best-case sample, or one -workload. Median latency, throughput, peak resident memory, allocation count, -compiled object size, final binary size, and clean and incremental compilation -time SHOULD be reported separately. - -### PJSON-PERF-002: Avoid avoidable work in common DOM operations - -The common paths SHOULD support: - -- one-lookup object access; -- traversal without copied key lists; -- moved child insertion without deep copying; -- array capacity reservation and amortized append; -- direct serialization to a caller-provided sink; -- schema compilation reuse; and -- parsing from byte spans without an intermediate NUL-terminated copy. - -Performance changes MUST preserve all safety budgets and MUST be checked by -correctness tests and sanitizers. - -### PJSON-PERF-003: Track regressions without overclaiming - -CI SHOULD retain historical benchmark artifacts or compare against the last -stable release on controlled runners. Initially, regressions larger than an -agreed threshold should produce a report rather than a flaky pass or fail. -Once runner stability is demonstrated, release gates MAY enforce per-workload -budgets. - -## 11. P2 build, packaging, and portability requirements - -### PJSON-BUILD-001: Be a well-behaved CMake subproject - -The project MUST export a namespaced target such as pjson::pjson and MUST NOT -modify parent-wide compiler flags, warning levels, language standards, -BUILD_TESTING, or unrelated cache variables when included with -add_subdirectory() or FetchContent. Developer-only tests, examples, benchmarks, -documentation, fuzzers, and install rules MUST default off when the project is -embedded. - -The minimum CMake version SHOULD be no higher than required by the library -implementation. CMake 3.15 compatibility is a useful portability target. If a -newer minimum remains necessary, the exact feature requiring it MUST be -documented and direct-source integration must remain supported. - -### PJSON-BUILD-002: Support static and shared consumption correctly - -Static and shared builds MUST work through build-tree and installed-package -usage. Public symbol visibility and export macros SHOULD be explicit rather -than depending solely on automatic Windows symbol export. Position-independent -code, runtime-library selection, and debug and release configuration handling -MUST behave correctly on supported platforms. - -Installed CMake and pkg-config metadata MUST be relocatable, contain no source -or build paths, and expose only actual consumer dependencies. - -### PJSON-BUILD-003: Publish immutable package inputs - -Release tags MUST be immutable and resolve to reviewed commits. Release source -archives and artifacts MUST include checksums. Package recipes SHOULD use an -immutable tag or commit plus a cryptographic hash rather than building a mutable -checkout. - -Official or documented recipes SHOULD cover Conan and vcpkg once their registry -submission and maintenance status are clear. Static and shared package -consumers MUST be built and executed in CI. - -### PJSON-BUILD-004: Define the supported platform matrix - -The project MUST publish its supported combinations of operating system, -architecture, compiler, standard library, C++ language level, and build type. -CI MUST exercise every combination claimed as supported or clearly distinguish -fully tested platforms from best-effort platforms. At minimum, the expected -general-purpose matrix is: - -- GCC and Clang on Linux; -- AppleClang on macOS; -- MSVC on Windows; -- x86-64 and arm64 where hosted runners are available; and -- Debug and optimized Release builds. - -If MinGW, 32-bit targets, Android, unusual double formats, or big-endian targets -are claimed, they require corresponding CI or periodic verification. - -### PJSON-BUILD-005: Keep optional features modular - -The RFC 8259 parser, serializer, and DOM SHOULD remain usable without JSON -Schema, regular-expression, networking, or benchmark dependencies. Optional -standards modules SHOULD have separate targets and headers with explicit -dependency and version contracts. Disabling an optional module MUST remove its -code and transitive dependencies from consumer builds. - -## 12. P1 and P2 verification requirements - -### PJSON-TEST-001: Keep conformance corpora mandatory for releases - -Release CI MUST fetch commit-pinned and integrity-verified conformance corpora -and fail if they are absent, empty, at the wrong revision, or produce an -unexpected case count. A local developer build MAY skip unavailable optional -corpora, but the skip must be conspicuous. - -Required suites include: - -- JSONTestSuite for parser acceptance and rejection; -- JSON-Schema-Test-Suite for every claimed schema dialect and vocabulary; and -- maintained RFC 6901, RFC 6902, and RFC 7396 cases for extension APIs. - -Accepted implementation-defined parser cases SHOULD be checked for structural -equality and stable reserialization, not only successful reparsing. - -### PJSON-TEST-002: Run differential and property tests - -The project SHOULD maintain tests for: - -- DOM versus SAX acceptance and value or event equivalence; -- string versus byte-span versus stream parsing; -- compact output reparsing to structural equality; -- stream output matching buffered output; -- copy, move, and swap invariants; -- Patch and Merge Patch atomicity; -- allocator provenance and injected allocation failure; and -- comparisons against one or more mature JSON implementations on the common, - standards-defined subset. - -Differences from comparison libraries MUST be placed in a small reviewed -allowlist with a reason and an expiry or review condition. - -### PJSON-TEST-003: Strengthen fuzzing - -Maintain separate fuzzers for DOM parsing, SAX and stream parsing, -serialization, Pointer and Patch, Merge Patch, and schema compilation and -validation. Fuzz invariants SHOULD include: - -- no crash, leak, undefined behavior, or unbounded work within configured - limits; -- DOM and SAX acceptance parity; -- parse of serialize producing structural equality for representable values; -- equivalent buffered and chunked-stream behavior; -- failed transactional operations leaving inputs unchanged; and -- diagnostics remaining within configured budgets. - -Smoke fuzzing MUST include inputs larger than 4 KiB as well as targeted seeds -for Unicode boundaries, embedded NUL, duplicate names, long numbers, deep and -wide containers, output limits, and aliasing mutations. Prefer active -continuous hosted fuzzing; otherwise run scheduled sustained fuzz jobs and -retain and minimize all findings. - -### PJSON-TEST-004: Require sanitizers and static analysis - -Every release candidate MUST pass the complete unit and conformance suite with: - -- AddressSanitizer; -- UndefinedBehaviorSanitizer; -- leak detection on a supported platform; and -- compiler warnings treated as errors for project sources. - -ThreadSanitizer SHOULD cover any documented concurrent-use guarantees. Memory -Sanitizer SHOULD only be claimed when the whole relevant dependency graph is -instrumented. If a sanitizer option is unsupported by the selected toolchain, -configuration MUST fail clearly rather than silently ignoring the request. - -Static analysis and CodeQL SHOULD remain enabled. Findings must be triaged, and -release criteria must require zero unresolved high-severity correctness or -security findings. - -### PJSON-TEST-005: Add regression tests for every defect - -Every correctness or security fix MUST first gain a minimal reproducer and then -retain it as a permanent test. The two initial mandatory regressions are: - -1. length-preserving access to an embedded-NUL object name; and -2. ancestor and descendant move assignment under sanitizers. - -The test suite must register every compiled case with the test runner. Release -CI SHOULD compare discovered and registered counts to prevent silent omission. - -## 13. P2 documentation and API-governance requirements - -### PJSON-DOC-001: Publish one precise behavioral contract - -Versioned documentation MUST define: - -- every JSON value representation and numeric boundary; -- parsing strictness, duplicate handling, and resource-limit defaults; -- error and exception behavior for each entry point; -- construction, auto-vivification, and null semantics; -- iterator, pointer, reference, and string-view invalidation; -- copy, move, swap, allocator, and aliasing behavior; -- serialization ordering, escaping, and numeric formatting; -- thread-safety guarantees; and -- exact conformance scope for every optional standard. - -Examples MUST use safe, non-vivifying APIs for reads and must not depend on -undocumented behavior. - -### PJSON-DOC-002: Maintain compatibility and migration guidance - -Semantic Versioning MUST cover documented source and behavioral contracts. If -ABI stability is not promised, documentation must state that consumers should -rebuild the library and dependents together. - -For each release, publish: - -- added, changed, deprecated, removed, fixed, and security-relevant behavior; -- migration notes for behavior changes; -- supported compiler and platform matrix; -- conformance-suite revisions and results; and -- benchmark methodology and comparison caveats. - -Changes to enum values, object ordering, number classification, duplicate-key -defaults, exception behavior, or serialization are compatibility changes and -must be versioned deliberately. Existing enum numeric values SHOULD NOT be -renumbered when an unsigned kind is added. - -### PJSON-DOC-003: Keep security and maintenance expectations explicit - -Maintain a private vulnerability-reporting path, supported-version table, -response targets, and coordinated-disclosure policy. Repository governance must -identify active maintainers and the process for reviewing significant API, -security, or compatibility changes. - -### PJSON-DOC-004: Classify compatibility impact before implementation - -Each requirement must be assigned a release-compatibility impact before its -implementation is merged: - -| Change class | Typical impact | -| --- | --- | -| Fix incorrect lookup or memory-unsafe behavior | Patch release, with regression tests | -| Add new overloads, factories, traversal, or structured errors | Minor release when source-compatible | -| Add a numeric variant that changes class layout | ABI break; require dependent binaries to rebuild and document it prominently | -| Change duplicate-key defaults, non-finite handling, numeric classification, or serialized spelling | Behavioral compatibility change; provide migration notes and use the SemVer level required by the published contract | -| Add a separate optional schema module | Minor release when it does not alter core behavior | -| Change object storage or iteration invalidation rules | Potential source, behavioral, and ABI break; require an explicit migration plan | - -The project MUST maintain tests for supported old behavior during deprecation -windows. A compatibility mode must have a removal version or review milestone -rather than becoming an undocumented permanent branch. - -## 14. P2 maintainability requirements - -### PJSON-MAINT-001: Share parser machinery - -DOM and SAX parsing currently have separate grammar implementations. They -SHOULD share tokenization, Unicode decoding, number classification, duplicate -handling, resource accounting, and error-location logic through a common core -parameterized by a DOM builder or event sink. - -The refactor MUST preserve public diagnostics and pass differential tests after -each stage. It must not turn the streaming SAX path into a whole-document -buffering implementation. - -### PJSON-MAINT-002: Isolate standards extensions and complex subsystems - -Schema validation, Pointer, Patch, Merge Patch, parsing, serialization, and DOM -storage SHOULD have clear internal module boundaries rather than accumulating -in a single implementation unit. Shared safety budgets and allocator rules must -remain centralized enough to prevent divergent enforcement. - -The split SHOULD reduce review and incremental-build cost without exposing -private implementation types or weakening the single public contract. - -## 15. P3 optional enhancements - -The following are valuable but are not prerequisites for a robust core DOM: - -- insertion-order-preserving object storage as a selectable policy; -- an exact arbitrary-precision integer or decimal type; -- user-defined type-conversion traits; -- JSON Lines or JSON Text Sequence helpers built above the single-document - parser; -- canonical JSON for a specifically named standard; -- zero-copy or immutable document views; -- C++17 std::string_view overloads in addition to the C++11 API; and -- a pull-parser or cursor API between SAX and a fully materialized DOM. - -Each optional feature must retain the same input validation, resource budgets, -diagnostics, and sanitizer and fuzz requirements as the core APIs. - -## 16. Delivery sequence - -The recommended implementation order is: - -1. Fix embedded-NUL key handling and add its regression matrix. -2. Fix ancestor and descendant move and swap safety and add sanitizer tests. -3. Add exact unsigned integer support and define the unrepresentable-number - policy. -4. Replace silent non-finite-to-null serialization with an explicit policy. -5. Make every parser front end stack-safe and behaviorally equivalent. -6. Align early duplicate detection and structured diagnostics. -7. Add direct traversal, generic child insertion, factories, checked indexing, - and serialization-result APIs. -8. Complete allocator coverage and document thread safety. -9. Establish performance baselines and optimize only with correctness gates in - place. -10. Implement full JSON Schema 2020-12 as a separately gated module, or retain - the accurately documented subset designation. -11. Harden package and release provenance and publish supported registry - packages. - -Steps 1 through 6 constitute the core correctness gate. Step 10 is independently -required before claiming JSON Schema 2020-12 compatibility. The strict, -fail-closed subset mode in PJSON-SCHEMA-000 should be delivered before expanding -the subset or beginning the full-dialect implementation. - -## 17. Definition of done - -The production-readiness effort is complete when all of the following are true: - -- every P0 requirement has a permanent regression test and passes sanitizers; -- supported integer values round-trip exactly across DOM and SAX APIs; -- valid object names are never truncated by a length-aware API; -- no public mutation operation can trigger undefined behavior through a - supported aliasing pattern; -- excessive depth or work returns a structured limit error rather than - crashing; -- all parser front ends agree on the pinned JSON conformance corpus; -- successful serialization never silently changes a stored value's JSON type; -- non-allocating object and array traversal is available; -- error codes, limits, invalidation, ownership, and thread safety are - documented; -- static and shared build-tree and installed-package consumers pass on every - claimed platform; -- all unit, property, differential, conformance, sanitizer, static-analysis, - package, and fuzz gates pass; -- benchmark results and methodology are published without unsupported claims; - and -- every advertised optional standard passes its declared conformance suite, - with deviations published explicitly. - -## Appendix A: confirmed 1.0.0 baseline defects - -This appendix records evidence from the reviewed baseline. It does not prescribe -implementation details. - -### A.1 Embedded-NUL name truncation - -The std::string overloads for member access delegate through c_str(). A document -can store both "a" and "a\u0000b", but lookup and erasure using a -three-byte std::string containing a, NUL, b operate on "a". - -Affected baseline areas in pjsonlib/src/pjson.cpp include the std::string -operator and find overloads around lines 2795-2819, hasKey around lines -4253-4260, and erase around lines 4313-4323. - -### A.2 Descendant move-assignment use-after-free - -When a parent is move-assigned from a referenced descendant using the same -allocator, assignment resets the parent before reading the descendant. An -AddressSanitizer run reports heap-use-after-free. - -The affected baseline implementation is pjsonlib/src/pjson.cpp around lines -1402-1417. - -### A.3 Unsigned integer precision loss - -Parsing the decimal representation of UINT64_MAX stores a double and serializes -it as 1.8446744073709552e+19 rather than preserving the integer exactly. - -The relevant baseline implementation is pjsonlib/src/pjson.cpp around lines -4028-4107. - -### A.4 Configurable stack exhaustion - -The default nesting limit is finite, but callers can request an arbitrarily high -limit while DOM and SAX parsing still recurse. A 100,000-level nested document -with a matching configured limit causes stack overflow under AddressSanitizer. - -### A.5 Silent schema weakening - -The current schema subset intentionally ignores unsupported keywords. For -example, a conditional schema using if and then can accept an instance that a -Draft 2020-12 validator rejects. This behavior is acceptable only while the -feature is clearly advertised as a subset; it is incompatible with a claim of -general Draft 2020-12 validation. - -## Appendix B: requirements checklist - -Status legend: [x] done, [~] partial (see `docs/featurerequest-response.md`), -[ ] deferred/tracked in `Todo.md`. - -- [x] PJSON-COR-001 — Preserve object keys byte-for-byte -- [x] PJSON-COR-002 — Make aliasing mutations memory-safe -- [x] PJSON-NUM-001 — Never silently corrupt an accepted number -- [x] PJSON-NUM-002 — Handle non-finite floating-point values explicitly -- [x] PJSON-NUM-003 — Define finite floating-point conversion precisely -- [x] PJSON-SEC-001 — Make nesting limits stack-safe -- [x] PJSON-PARSE-001 — Keep all parser front ends behaviorally equivalent -- [x] PJSON-PARSE-002 — Apply duplicate-key policy early and consistently -- [x] PJSON-API-001 — Provide non-allocating traversal -- [x] PJSON-API-002 — Complete construction and mutation primitives -- [x] PJSON-API-003 — Separate safe reads from vivifying writes -- [x] PJSON-API-004 — Define type conversion and equality precisely -- [x] PJSON-API-005 — Provide a structured error model -- [x] PJSON-API-006 — Make ownership and allocator behavior complete for the - documented allocator scope -- [x] PJSON-API-007 — Document thread safety -- [x] PJSON-SER-001 — Guarantee valid and stable JSON output -- [x] PJSON-SER-002 — Preserve deterministic output when requested -- [x] PJSON-SEC-002 — Use uniform, overflow-safe resource budgets -- [x] PJSON-SEC-003 — Preserve transactional mutation guarantees -- [x] PJSON-SEC-004 — Treat regexes and external resources as hostile -- [x] PJSON-SCHEMA-000 — Make subset validation fail closed when requested -- [x] PJSON-SCHEMA-001 — Implement an explicit dialect contract -- [~] PJSON-SCHEMA-002 — Compile and validate schemas separately -- [~] PJSON-SCHEMA-003 — Cover the Draft 2020-12 vocabulary -- [x] PJSON-SCHEMA-004 — Make reference resolution secure and embeddable -- [x] PJSON-SCHEMA-005 — Provide actionable diagnostics -- [~] PJSON-SCHEMA-006 — Prove conformance -- [x] PJSON-EXT-001 — JSON Pointer conformance -- [x] PJSON-EXT-002 — JSON Patch conformance -- [x] PJSON-EXT-003 — JSON Merge Patch conformance -- [~] PJSON-PERF-001 — Maintain representative benchmarks -- [~] PJSON-PERF-002 — Avoid avoidable work in common DOM operations -- [~] PJSON-PERF-003 — Track regressions without overclaiming -- [x] PJSON-BUILD-001 — Be a well-behaved CMake subproject -- [x] PJSON-BUILD-002 — Support static and shared consumption correctly -- [x] PJSON-BUILD-003 — Publish immutable package inputs -- [x] PJSON-BUILD-004 — Define the supported platform matrix -- [x] PJSON-BUILD-005 — Keep optional features modular -- [x] PJSON-TEST-001 — Keep conformance corpora mandatory for releases -- [x] PJSON-TEST-002 — Run differential and property tests -- [x] PJSON-TEST-003 — Strengthen fuzzing -- [x] PJSON-TEST-004 — Require sanitizers and static analysis -- [x] PJSON-TEST-005 — Add regression tests for every defect -- [x] PJSON-DOC-001 — Publish one precise behavioral contract -- [x] PJSON-DOC-002 — Maintain compatibility and migration guidance -- [x] PJSON-DOC-003 — Keep security and maintenance expectations explicit -- [x] PJSON-DOC-004 — Classify compatibility impact before implementation -- [~] PJSON-MAINT-001 — Share parser machinery -- [~] PJSON-MAINT-002 — Isolate standards extensions and complex subsystems diff --git a/docs/migration-from-nlohmann-json.md b/docs/migration-from-nlohmann-json.md index 9d02e83..22bcffe 100644 --- a/docs/migration-from-nlohmann-json.md +++ b/docs/migration-from-nlohmann-json.md @@ -258,7 +258,6 @@ pjson::SerializeOptions options = pjson::SerializeOptions::prettyPrinted(); options.indentWidth = 4; options.indentCharacter = ' '; options.escapeNonAscii = true; -options.keyOrder = pjson::SerializeOptions::AscendingKeys; options.maxOutputBytes = size_t(64) * 1024 * 1024; std::string text = document.toString(options); @@ -266,10 +265,11 @@ document.write(output, options); ``` Default construction selects compact output, two-space indentation, a space -indent character, UTF-8 output, ascending keys, and a 64 MiB output limit.
