Week 4 Meetings and Activities

Weekly Project Sync Meeting 4​

(June 16, 2026)

Attendees​

Discussion​

  • Reviewed the need to align the PHP-side license expression parser with the shared SPDX parser contract.
  • Discussed why the PHP parser is required for UI and REST API workflows where users manually create or edit license expressions.
  • Reviewed the shared parser contract and decided that the PHP implementation should follow the same grammar, AST format, canonical behavior, and shared test corpus as the native C parser.
  • Discussed keeping current database and UI behavior unchanged while replacing parser internals.
  • Reviewed the need for a compatibility adapter from the shared contract AST to the existing PR storage AST.
  • Discussed expression editing behavior in the clearing view and how license/operator nodes should be validated.
  • Reviewed UI problems in the expression editor, including incomplete license suggestions when editing license nodes.
  • Discussed keeping the Conclude Expression action consistently available in the clearing view.
  • Reviewed how manually edited expressions should be saved and displayed consistently across clearing decisions and browser views.

Activities Done in Week 04​

  • Implemented a contract-compatible PHP SPDX expression parser for the web/UI layer.
  • Aligned the PHP parser grammar with the shared SPDX parser contract used by the native C implementation.
  • Added PHP parser support for SPDX operators such as AND, OR, and WITH.
  • Added support for parentheses, exceptions, LicenseRef, DocumentRef, NONE, and NOASSERTION handling in the PHP parser flow.
  • Added canonicalization behavior so manually entered expressions are normalized consistently.
  • Added a compatibility adapter so the new PHP parser output can still be stored using the existing license expression AST format.
  • Added PHPUnit coverage for the PHP parser using the shared parser test corpus.
  • Replaced PHP-side expression validation/editing paths to use the new contract-compatible parser.
  • Verified that expression editing in the clearing view continues to save expressions correctly.
  • Fixed the expression editor so license nodes can fetch and suggest available license references properly.
  • Updated the clearing view so expression rows render with the same column structure as normal license rows.
  • Kept the expression edit action available for expression rows while preserving existing clearing behavior.
  • Updated the Conclude Expression action so it remains available consistently in the clearing view.
  • Removed the redundant add-license action from the Conclude Expression modal to avoid overlap with User Decision behavior.
  • Performed local UI validation for manually edited expressions and confirmed that saved expressions remain visible after refresh.

Next Steps​

  • Continue checking UI consistency between expression rows and simple license rows.
  • Review License Browser summary and histogram behavior for concluded expressions.
  • Improve expression display behavior in tree view and flat view.
  • Validate API behavior for manually created and edited license expressions.
  • Continue testing expression edits, clearing decisions, and refresh behavior across multiple uploads.
