Verified fuzz infrastructure dependencies: - PASS: cargo-fuzz 0.13.1 installed - PASS: Rust nightly 1.98.0 toolchain supports fuzzing - PASS: fuzz/fuzz_targets/ directory exists with 5 working targets - FAIL: content.rs fuzz target does not exist (critical dependency issue) Parent beads (bf-2mzuw, bf-2g0kn) reference non-existent 'content' fuzz target. Available targets: lexer, object_parser, xref, stream_decoder, cmap_parser. Closes bf-2pq5z

# Fuzz Dependency Verification - bf-2pq5z
|
|
|
|
## Task
|
|
Verify fuzz dependencies are installed for the content.rs fuzz harness.
|
|
|
|
## Findings
|
|
|
|
### ✅ PASS: cargo-fuzz Installation
|
|
- **Status**: Installed and working
|
|
- **Version**: cargo-fuzz 0.13.1
|
|
- **Command**: `cargo fuzz --version` succeeded
|
|
|
|
### ✅ PASS: Rust Toolchain
|
|
- **Status**: Supports fuzzing
|
|
- **Version**: rustc 1.98.0-nightly (f20a92ec0 2026-06-07)
|
|
- **Cargo**: 1.98.0-nightly (0b1123a48 2026-06-01)
|
|
|
|
### ✅ PASS: Fuzz Harness Directory
|
|
- **Status**: Directory exists and contains fuzz targets
|
|
- **Location**: `fuzz/fuzz_targets/`
|
|
- **Available targets**: 5 fuzz targets found
|
|
- `cmap_parser.rs`
|
|
- `lexer.rs`
|
|
- `object_parser.rs`
|
|
- `stream_decoder.rs`
|
|
- `xref.rs`
|
|
|
|
### ❌ FAIL: content.rs Fuzz Target
|
|
- **Status**: NOT FOUND
|
|
- **Expected**: `fuzz/fuzz_targets/content.rs`
|
|
- **Found**: The file does not exist
|
|
- **Verified by**: `test -f fuzz/fuzz_targets/content.rs` returned false
|
|
|
|
## Critical Issue
|
|
|
|
The parent beads (bf-2mzuw, bf-2g0kn) reference a non-existent `content` fuzz target:
|
|
|
|
1. **bf-2mzuw** (closed) claims to verify "the content.rs fuzz harness compiles" with command `cargo fuzz build content`
|
|
2. **bf-2g0kn** (in_progress) expects to run `cargo fuzz run content -- -max_total_time=5`
|
|
3. **fuzz/Cargo.toml** defines 5 fuzz targets but NO `content` target
|
|
|
|
This is a **dependency chain inconsistency**. The content.rs fuzz target was never created, but dependent beads were written as if it existed.
|
|
|
|
## Available Fuzz Targets
|
|
|
|
The actual fuzz infrastructure includes these working targets:
|
|
- `lexer` - PDF lexer fuzzing
|
|
- `object_parser` - PDF object parsing fuzzing
|
|
- `xref` - Cross-reference table fuzzing
|
|
- `stream_decoder` - PDF stream decoding fuzzing
|
|
- `cmap_parser` - Character map parsing fuzzing
|
|
|
|
## Recommendation
|
|
|
|
Before running fuzz tests (bf-2g0kn), the dependency chain needs resolution:
|
|
1. Either create the missing `content.rs` fuzz target, OR
|
|
2. Update dependent beads to reference existing fuzz targets
|
|
|
|
## Acceptance Criteria Status
|
|
|
|
| Criterion | Status | Result |
|
|
|-----------|--------|--------|
|
|
| `cargo fuzz --version` succeeds | ✅ PASS | Version 0.13.1 |
|
|
| fuzz/fuzz_targets/content.rs exists | ❌ FAIL | File NOT found |
|
|
| No missing dependency errors | ⚠️ WARN | Missing target itself |
|
|
|
|
## Conclusion
|
|
|
|
Fuzz **dependencies** (cargo-fuzz, Rust toolchain, harness infrastructure) are properly installed and working. However, the specific **content.rs fuzz target** referenced by this bead and its parent does not exist in the codebase.
|
|
|
|
**Note**: This verification exposes a pre-existing dependency chain issue that existed before this bead started. The parent bead (bf-2mzuw) was incorrectly closed despite the content.rs target not existing.
