JavaScript PDF Fixture Verification (bf-5wo1t)

Task Summary

Located and verified the JavaScript PDF fixture file from the previous bead step exists.

Findings

Primary JavaScript PDF Fixture

File Path: /home/coding/pdftract/tests/fixtures/security/embedded-js.pdf

Status: ✅ VERIFIED

File Details:

  • Size: 1.1K (1,120 bytes)
  • Format: PDF-1.4
  • Readable: Yes
  • Created: July 5, 2026 18:05

Generator Script: /home/coding/pdftract/tests/fixtures/security/generate_embedded_js.py (3,289 bytes)

JavaScript Content

The fixture contains documented JavaScript actions (from the generator script):

  1. Catalog /OpenAction: app.alert("pwn")
  2. Page 0 /AA /O (open action): app.alert('page_open')
  3. Page 1 annotation /A: app.alert('annot_action')

Current Extraction Behavior

According to previous testing (bf-36gzd), pdftract currently extracts only 1 JavaScript action from this fixture:

  • Extracted: app.alert("pwn") at catalog.openaction
  • Not Extracted: Page-level and annotation JavaScript actions

This may indicate incomplete JavaScript extraction or differences in PDF structure.

Secondary Fixture (with parsing issue)

File Path: /home/coding/pdftract/tests/document_model/fixtures/js_in_openaction.pdf

Status: ⚠️ Parsing Error

File Details:

  • Size: 632 bytes
  • Format: PDF-1.4
  • Issue: Expected output shows "No /Root reference in trailer" error
  • Despite this error, hexdump analysis suggests the file structure appears valid

CLI Usage

For testing JavaScript extraction:

pdftract extract tests/fixtures/security/embedded-js.pdf

Acceptance Criteria Status

  • JavaScript PDF fixture file is located
  • File path is documented: /home/coding/pdftract/tests/fixtures/security/embedded-js.pdf
  • File is readable: Yes (1.1K, PDF-1.4 format)
  • File size is reasonable (> 0 bytes): 1,120 bytes

Verification Notes

The primary JavaScript fixture embedded-js.pdf is verified and ready for use. The file contains multiple JavaScript actions and is successfully parsed by pdftract, making it suitable for JavaScript detection and extraction testing.
