Added comprehensive documentation for orphaned process verification:
- Detailed explanations for three default process patterns:
* pdftract mcp (MCP server subprocess)
* TH-0 (test harness - hyphen variant)
* TH_0 (test harness - underscore variant)
- Each pattern includes:
* What it is and when it appears
* Typical spawn patterns
* Why it orphans (root causes)
* Detection examples with expected output
* Manual cleanup commands
- Manual verification walkthrough with 4 scenarios:
* After a test run (normal workflow)
* Before starting a test run (pre-flight check)
* Investigating a leaking test (binary search)
* CI post-test verification (automation)
- 5 common orphan scenarios with symptoms, verification, and fixes:
* Test timeout leaves children alive
* Panic before cleanup
* Undrained Stdio::piped() blocks wait()
* Port already in use from previous run
* Fuzz harness leaves target processes
All examples include realistic command-line output and reference existing
cleanup patterns (OrphanedProcessGuard, RAII).

Create comprehensive documentation for orphaned process verification
system at docs/test-hygiene/orphaned-process-verification.md
The documentation includes:
- Overview of orphaned process verification and why it matters
- Usage instructions for scripts/check-orphaned-processes.sh
- Verification methods (shell script, Rust helpers, CI integration)
- Best practices for RAII guards and process cleanup
- CI integration examples
- Troubleshooting guide
Closes bf-1lghw6. Verification: notes/bf-1lghw6.md
- Add Push Status section documenting remote push blocked by large files
- Issue is pre-existing: large binary test files (60MB and 235MB) exceed GitHub limits
- Changes are committed locally (70be8391), push blocked by repository infrastructure
- Implementation is complete and functional, awaiting repository maintainer resolution
Verification: notes/bf-i1e5d.md
- Add post-test verification steps after all test execution points in pdftract-ci.yaml
- Verification runs in 6 locations: glibc (cgroup v2/v1/no-cgroup) and musl (cgroup v2/v1/no-cgroup)
- Integrates existing check-orphaned-processes.sh script via post-test-check.sh wrapper
- Verification automatically kills orphaned processes and reports status
- All acceptance criteria PASS: verification runs after tests, output visible in logs, orphans flagged, works in both CI and local environments
Verification: notes/bf-i1e5d.md
Closes bf-i1e5d
- Add ProcessGuard RAII struct for deterministic process cleanup
- Implement wait_with_timeout helper to prevent indefinite blocking
- Replace all bare child.wait() calls with bounded timeouts
- Update all test cases to bind to port :0 (avoid collisions)
- Add StdioConfig enum for proper pipe handling (Piped/Null)
- Add read_initial_output_with_timeout for safe pipe reading
- Ensure no orphaned processes via RAII cleanup on Drop
Closes bf-119ys
Verification: notes/bf-119ys.md
Verify that cargo nextest timeout configuration is complete and correct.
All three profiles (default, ci, ci-proptest) have proper slow-timeout
and terminate-after settings to prevent test hangs.
Closes bf-5i310
Acceptance criteria:
- PASS: all profiles have slow-timeout configured
- PASS: all profiles have terminate-after set
- PASS: configuration is well-documented with rationale
- PASS: timeout enforcement is active
Verification: notes/bf-5i310.md
- Analyzed 5 timing flags: 2 working (libtest-json-plus, libtest-json)
- Documented JSON formats capture per-test exec_time successfully
- Slow test flags work but showed no output (no tests exceeded 60s threshold)
- Recommends --message-format=libtest-json-plus for CI timing data
Closes bf-27zav
Test each cargo nextest timing flag from bf-4wz6v documentation:
- --message-format=libtest-json-plus (2.0M, JSON with exec_time)
- --message-format=libtest-json (2.0M, JSON format)
- --message-format-version=0.1 (2.0M, versioned JSON)
- --message-format-version=1.0 (error, invalid version range)
- --message-format-version=1 (error, invalid format)
- --status-level=slow (112K, slow test detection)
- --final-status-level=slow (412K, slow test summary)
Acceptance criteria:
- PASS: Output file exists for each tested flag (8 files)
- PASS: Each file named after the flag it tests
- PASS: At least 3 flags tested (7 unique flags)
Closes bf-3m477
- Ran cargo nextest run -p pdftract-core --lib to establish baseline
- Captured 2,902 lib tests in 4.527s (2857 passed, 45 failed, 2 skipped)
- Saved output to notes/bf-mge0o-baseline.log (411.8KB)
- Created verification note at notes/bf-2n36a.md
- Output shows standard nextest format for comparison with timing-flagged runs
Closes bf-2n36a
Add summary of timing flags identified in bf-52v1t research:
- Primary candidates: --message-format libtest-json variants for per-test timing
- Secondary candidates: --status-level and --final-status-level for slow detection
- Config: slow-timeout setting for threshold definition
- Excluded: --timings flag (build timing, not test timing)
Closes bf-4wz6v
Analyzed test failures from bf-1wczm execution. Found:
- No test hangs detected (all modules completed in <1s)
- 11 test failures across 2 modules due to fixture issues
- encoding_recovery: 5 PDF fixtures corrupted (missing /Root reference, 0 pages)
- cjk_encoding: 5 tests failed due to path resolution issues
Proposed fix strategy:
1. Regenerate corrupted PDF fixtures in tests/fixtures/encoding/
2. Fix path resolution using CARGO_MANIFEST_DIR in cjk_encoding.rs
3. Add fixture validation to CI
Closes bf-n5w42.
Adds serde_yaml = { version = "0.9" } to fuzz/Cargo.toml to support the profile_yaml fuzz target. Version matches pdftract-core's serde_yaml dependency (0.9).
Closes bf-3mull
Analyzed all 7 fuzz targets and their pdftract-core feature requirements.
Confirmed that current configuration is correct and complete:
- All targets build successfully
- 'profiles' feature correctly enables serde_yaml for profile_yaml.rs
- Workspace path syntax is correct
- serde_yaml symbols verified in profile_yaml binary
No dependency issues found - current configuration is PASS.
Closes bf-4i7rs.
Research findings documenting available cargo nextest output formats
that support timing data:
- JUnit XML (stable, primary format)
- Libtest JSON (experimental, compatibility-focused)
- Test list JSON (for listing only, no timing)
Closes bf-49mfs. References: https://nexte.st/docs/machine-readable/
