The detect_xfa function was already implemented in the codebase at the time of bead assignment. This note documents the verification of the existing implementation against the bead's acceptance criteria. All 6 tests pass, covering all acceptance criteria: - XFA stream presence → true - XFA array packet form → true - No XFA key → false - XFA null → false - No AcroForm → false - XFA as indirect reference → true Co-Authored-By: Claude Opus 4.7 <noreply@anthropic.com>

# pdftract-342k4: XFA Detection — Verification Note
|
|
|
|
## Summary
|
|
|
|
XFA detection (`detect_xfa`) was **already implemented** in the codebase at the time of bead assignment. No implementation work was required.
|
|
|
|
## Implementation Status
|
|
|
|
### Function Location
|
|
- **File:** `crates/pdftract-core/src/forms/mod.rs`
|
|
- **Lines:** 66-72
|
|
- **Export:** Public API in `lib.rs` line 73
|
|
|
|
### Implementation
|
|
```rust
|
|
pub fn detect_xfa(acroform: &Option<PdfDict>) -> bool {
|
|
acroform
|
|
.as_ref()
|
|
.and_then(|af| af.get("XFA"))
|
|
.map(|xfa| !matches!(xfa, PdfObject::Null))
|
|
.unwrap_or(false)
|
|
}
|
|
```
|
|
|
|
This matches the bead's specification exactly.
|
|
|
|
## Acceptance Criteria Verification
|
|
|
|
All acceptance criteria PASS:
|
|
|
|
| # | Criteria | Test | Status |
|
|
|---|----------|------|--------|
|
|
| 1 | PDF with AcroForm /XFA stream → true | `test_detect_xfa_xfa_stream` | ✅ PASS |
|
|
| 2 | PDF with AcroForm /XFA [name, stream, ...] (packet form) → true | `test_detect_xfa_xfa_array_packet_form` | ✅ PASS |
|
|
| 3 | PDF with AcroForm but no /XFA key → false | `test_detect_xfa_no_xfa_key` | ✅ PASS |
|
|
| 4 | PDF with AcroForm /XFA null → false | `test_detect_xfa_xfa_null` | ✅ PASS |
|
|
| 5 | PDF with no AcroForm → false | `test_detect_xfa_no_acroform` | ✅ PASS |
|
|
|
|
**Additional coverage:** `test_detect_xfa_xfa_ref` covers indirect reference handling (also returns true).
|
|
|
|
## Test Run
|
|
|
|
```bash
|
|
$ cargo nextest run -p pdftract-core --lib detect_xfa
|
|
