This draft extracts a small, tests-only first slice from my JSON/YAJL investigation onto upstream v3/master at 1ebdc390b47ab033c8267130ce83130f235aed20 (the current tip when prepared).
Only test/test-cases/regression/request-body-parser-json.json changes: five additional native regression cases, with the six existing cases retained unchanged. No production code, parser library, build files, dependencies or CI workflows are changed.
The cases cover original number text (1E+02), duplicate-key values and multiplicity, partial extraction and error flags after a depth-limit failure, numeric-looking keys/strings versus number tokens (including negative zero and an array-element name), and path restoration after a dotted parent key.
The existing native regression runner is used. Each new rule chain expects HTTP 418 and a case-specific log marker only when its asserted conditions match.
why
This follows the proposed “lock behaviour first, independent of the library” step in #3308.
The additional number/path coverage incorporates ideas and edge cases from my jsonbench contributions:
The tests exercise ModSecurity itself. No jsonbench adapter implementation is copied or treated as ModSecurity's specification.
This is deliberately not the complete baseline or all of step 1. The larger investigation's byte-level/chunk/lifecycle/writer helpers, generated results, extensive reports and requirements/policy profiles stay outside this initial PR so that the native-test integration and expectations can be reviewed separately.
The depth-failure case characterizes current partial extraction; it does not settle the atomic-rollback policy question or propose retaining partial arguments forever. An intentional behaviour change should revisit that expectation explicitly.
validation
Verified that the prepared branch is one commit ahead and zero behind upstream, with one changed file and 242 added lines.
Reused the regression-test file from investigation commit dd63a59e3a993faf4e74b08979e39986e1df4d2c; the six upstream cases are unchanged.
Parsed the five added request payloads locally and checked their declared Content-Length values against their byte lengths.
Confirmed that the file is already registered in test/test-suite.in.
No fresh ModSecurity build or runtime test was completed on this updated base. Local repository cloning was unavailable in the preparation environment. Historical investigation results are not claimed as results for this PR; fresh runtime/CI validation remains pending.
After a normal test-enabled build with YAJL and debug logging enabled, run from the repository root:
make check TESTS=test/test-cases/regression/request-body-parser-json.json
Run the full make check suite for broader integration coverage.
review requested
Hi @fzipi, hi @airween — would this native-test first slice be a useful starting point for step 1? Feedback on the expectations, especially characterization versus intended policy, and on which groups should come next would help shape follow-up work.
Keeping this as a draft until the scope and expectations have been reviewed and the updated base has fresh runtime validation.
Port five existing native regression cases from
dd63a59
onto the current upstream v3/master without changing production code.
Cover original number text, duplicate-key multiplicity, partial arguments
and error flags after a depth-limit failure, numeric-looking keys and
strings, and dotted-parent path restoration. The additional number/path
coverage incorporates ideas from digitalwave/jsonbench PRs #4 and #5.
Keep investigation helpers, generated results and proposed policy changes
outside this focused first slice. Related to owasp-modsecurity#3308.

Walkthrough
The PR adds a ModSecurity JSON test package with request and audit harnesses, native regression cases, clean-build and profile-run tooling, CI workflows, recorded test results, and documentation. It does not change production JSON processing code.
Five native regression cases cover number text, duplicate keys, depth limits, and dotted keys. The request harness adds characterization and proposed-requirement cases for parsing, chunking, limits, encodings, and transaction sequences.
Audit and content-offset coverage test/json-baseline/audit_probe.cc, test/json-baseline/extended_audit_probe.cc, test/json-baseline/run_audit.py, test/json-baseline/run_extended_audit.py
The audit harnesses check transaction JSON, part selections, byte inputs, repeated serialization, lifecycle behavior, and content-offset responses.
Build, verification, and profile execution test/json-baseline/tools/*, test/json-baseline/build-*.sh, test/json-baseline/repository-template/.github/workflows/*, .github/workflows/json-tests.yml, test/Makefile.am
The tooling prepares and builds source checkouts, verifies build provenance and probe artifacts, validates reports, runs selected profiles, and uploads CI artifacts.
Recorded results and provenance test/json-baseline/results/*, doc/json-pr-extension/*.json, doc/json-pr-extension/full-v3-*.json, doc/json-yajl-provenance.json
JSON reports record baseline, characterization, requirements, audit, native, sanitizer, and build outcomes with source and execution metadata.
Baseline and package documentation README.JSON-TESTS.md, doc/*JSON-YAJL*, doc/*json-yajl*, doc/json-pr-extension/*.md, doc/reference/*
The documents describe historical JSON behavior, test coverage, reproduction, provenance, validation results, package scope, and limitations.

Explanation
The title names the main change: adding native JSON characterization test cases ahead of a YAJL replacement. The changeset adds a JSON regression test package, probes, helpers, CI workflows, and reports, and the objectives state the purpose is to lock current JSON behavior before replacing YAJL. The title is specific, short, and matches the primary intent, though it does not mention the CI workflow, probes, or documentation. This is a reasonable scope for a title.

- Line 39: Update the JSON workflow’s probe-generation invocation so ordinary
pull requests can run the JSON suites when production files change; use the
separate pinned-source preparation flow for baseline verification, or an
established current-checkout mode that avoids the fixed-ORIGINAL change
rejection in source_metadata().
Review comments at @doc/json-pr-extension/README.en.md:
- Around line 123-124: Update the reproduction instructions around the
prepare_source.py command to make clear that it selects source revision 1ebdc390
and does not reproduce the historical results. Direct readers to the historical
helper revision for reproducing those results, or explicitly label this command
as a new run against the updated source.
Review comments at @test/json-baseline/run_extended_audit.py:
- Line 259: Update the fresh audit report construction in run_extended_audit so
production_base comes from the verified build metadata for that execution; if
the source is unknown, omit the field. Preserve archived reports unchanged and
do not retain the hard-coded October baseline for new results.
Review comments at @test/json-baseline/run_extended.py:
- Line 184: Update the report construction in run_extended.py so the
production_commit field uses the verified source commit supplied by the build
manifest when run_all.py runs the suite, rather than a hard-coded older commit.
Pass that verified value through the existing build and test flow to both
generated request reports.

Pass the verified build manifest to expanded request and audit reports;
unknown standalone source identity is null instead of an October SHA.

Fix the post-build rejection of others/libinjection in the JSON jobs.
Keep input and fresh-checkout verification strict, then record non-ignored
files generated by successful bootstrap/configure/make in the root and
recursive submodules. Validate their paths and SHA-256 hashes both after
building and before running suites. New, changed, missing or symlinked files
remain errors; tracked source and gitlink checks are not disabled.
Align both JSON workflows with ci_new.yml's checkout@v7, full history,
recursive submodules, build dependencies and nproc parallelism. Retain
Ubuntu 26.04, dynamic Lua selection and all seven test suites. Print build
phase/log paths and retain the generated-file inventory with CI evidence.
Validation: 12 new local regression tests pass using real Git submodules,
nested submodules, Libtool-generated macros and compiled C++ fixtures.
They reproduce the old rejection and exercise normal profile preflight plus
negative integrity checks. Python AST, workflow YAML and shell syntax pass.
Full ModSecurity execution and external analysis must be checked on this head.
No production changes, archived-result rewrites or Sonar suppressions.

Remove the input-checkout prebuild before build.py.
build.py checks the --source checkout strictly before it clones and builds. A normal sh -e ./build.sh, ./configure, and make -j2 run in that checkout can leave non-ignored generated files in others/libinjection. The check then rejects the checkout before the managed build starts. The managed clean build already runs bootstrap, configure, and make on the fresh clone, so the prebuild steps are not needed.

Split the deeply nested request probe into focused lifecycle functions.
Use scoped ownership for resolved values and the engine's matching cleanup
API for intervention strings. Add dedicated ProbeError and byte-safe shared
hex helpers, document intentional logging callbacks, and use string views
and raw literals for applicable fixtures. Distribute and hash both new
headers so shared helper changes cannot bypass probe verification.
Address all five open CodeRabbit findings: reject empty native/case suites,
classify unavailable audit probes and dependent controls as BLOCKED,
retain sensitivity failures and completed reports, and remove the redundant
preparation build from companion instructions. Keep genuine requirements
failures and existing JSON expectations unchanged. Refactor the reported
exception tests to prepare inputs outside assertRaises.
Validation: 121 local harness self-tests pass, including 26 new tests and
real C++17 -Wall -Wextra -Werror helper/no-YAJL compilations. AST comparisons
confirm unchanged request case definitions and behavioral/audit assertions.
These checks are not a full ModSecurity/WITH_YAJL execution or Sonar scan;

PermissionError from launching a non-executable probe sets is_blocked to true,
matching the audit runner’s behavior. Preserve the existing FileNotFoundError
and probe exit=77 classifications and the resulting BLOCKED/FAIL status mapping.

Record a probe launch failure instead of aborting the report.
If --probe exists but lacks execute permission, subprocess.run() raises PermissionError. The per-case handler does not catch it. The runner then exits before writing any case report. Catch probe launch errors and record an unavailable probe as BLOCKED. The audit runner already records this condition as BLOCKED. (raw.githubusercontent.com)

Skip sensitivity controls when any case is BLOCKED or FAIL.
With --sensitivity, a probe that exits 77 marks every selected case BLOCKED. The control loop still runs, calls the probe again for each control, and records each control as FAIL with the message control did not reach an assertion. The report then counts these controls as failures, which misstates a blocked state as test failures. Gate the controls on the case counts, as run.py does. Keep the suite check before the gate so its usage error still appears.

Classify a non-executable probe as BLOCKED.
If --probe names a file without execute permission, observe() raises PermissionError. This handler records every case as FAIL, although no JSON assertion ran. Classify that launch error as BLOCKED, as the audit runner does for the same condition. (raw.githubusercontent.com)

what
This draft extracts a small, tests-only first slice from my JSON/YAJL investigation onto upstream
v3/masterat1ebdc390b47ab033c8267130ce83130f235aed20(the current tip when prepared).Only
test/test-cases/regression/request-body-parser-json.jsonchanges: five additional native regression cases, with the six existing cases retained unchanged. No production code, parser library, build files, dependencies or CI workflows are changed.The cases cover original number text (
1E+02), duplicate-key values and multiplicity, partial extraction and error flags after a depth-limit failure, numeric-looking keys/strings versus number tokens (including negative zero and an array-element name), and path restoration after a dotted parent key.The existing native regression runner is used. Each new rule chain expects HTTP 418 and a case-specific log marker only when its asserted conditions match.
why
This follows the proposed “lock behaviour first, independent of the library” step in #3308.
The additional number/path coverage incorporates ideas and edge cases from my jsonbench contributions:
The tests exercise ModSecurity itself. No jsonbench adapter implementation is copied or treated as ModSecurity's specification.
This is deliberately not the complete baseline or all of step 1. The larger investigation's byte-level/chunk/lifecycle/writer helpers, generated results, extensive reports and requirements/policy profiles stay outside this initial PR so that the native-test integration and expectations can be reviewed separately.
The depth-failure case characterizes current partial extraction; it does not settle the atomic-rollback policy question or propose retaining partial arguments forever. An intentional behaviour change should revisit that expectation explicitly.

Hi @fzipi, hi @airween — would this native-test first slice be a useful starting point for step 1? Feedback on the expectations, especially characterization versus intended policy, and on which groups should come next would help shape follow-up work.
Keeping this as a draft until the scope and expectations have been reviewed and the updated base has fresh runtime validation.
