bf-32by8-step3: Execute pdftract command with captured output

State: FAIL

Date: 2026-07-06

Command Executed

unset RUST_LOG; cargo run -- extract tests/fixtures/encoding/fingerprint-match.pdf --json - 2>&1

Exit Code: 1 (failure)

Captured Output Summary

Build Phase

  • Warnings: 205 warnings (unused imports, unused variables, dead code)
  • Build Status: SUCCESS (completed in 43.78s)
  • Binary: target/debug/pdftract

Execution Result

Running `target/debug/pdftract extract tests/fixtures/encoding/fingerprint-match.pdf --json -`
Error: Failed to extract PDF

Detailed Output Structure

  1. Compiler warnings - 205 warnings about unused code (does not affect functionality)
  2. Build completion - "Finished dev profile" message
  3. Execution start - "Running" message with full command
  4. Error - "Failed to extract PDF"
  5. Exit code - 1

Analysis

  1. RUST_LOG State: ✓ Confirmed unset

    • The command explicitly ran with unset RUST_LOG before invocation
    • No log output was produced (would have appeared if RUST_LOG was set)

  2. Exit Code: 1 (failure)

    • Non-zero exit code indicates the command failed
    • The error message "Failed to extract PDF" suggests an extraction issue

  3. Output Streams:

    • stdout: No JSON output (extraction failed before producing output)
    • stderr: Error message "Failed to extract PDF" + compiler warnings

Next Steps

The exit code 1 and error message indicate:

  • The command execution was captured correctly
  • RUST_LOG was successfully unset (no log output appeared)
  • The PDF extraction failed for some reason (to be investigated in subsequent steps)

Acceptance Criteria Status

  • ✅ Run unset RUST_LOG; cargo run -- -i <fixture> -o - 2>&1 (adapted to correct syntax) - PASS
  • ✅ Capture both stdout and stderr to a temp file or variable - PASS
  • ✅ Record the command exit code (Exit code: 1) - PASS
  • ✅ Save captured output to notes/bf-32by8-step3.md - PASS (this file)
