From 5d3111b7e6b9bfb3ad63ee2fe82ceb2613f38e36 Mon Sep 17 00:00:00 2001 From: Femi John Date: Tue, 28 Apr 2026 21:03:15 +0100 Subject: [PATCH 1/4] feat: Implement optional fields validation enhancement - Added comprehensive validation for optional fields in the Dongle smart contract. - Enhanced URL validation with protocol, length, and domain checks. - Enhanced IPFS CID validation for CIDv0 and CIDv1 formats. - Introduced new wrapper functions for validating optional fields: `validate_optional_website`, `validate_optional_logo_cid`, `validate_optional_metadata_cid`, and `validate_optional_comment_cid`. - Integrated validation into project registration and update processes. - Updated review submission and update processes to include comment CID validation. - Created a new test suite for optional field validation with 40+ test cases covering all scenarios. - Added detailed documentation for validation specifications, quick reference, and implementation summary. - Ensured all changes are backwards compatible with existing functionality. --- CHANGELOG.md | 317 ++++++++++++ CODE_CHANGES.md | 449 ++++++++++++++++ IMPLEMENTATION_SUMMARY.md | 374 ++++++++++++++ IMPLEMENTATION_VERIFICATION.md | 489 ++++++++++++++++++ QUICK_REFERENCE.md | 328 ++++++++++++ VALIDATION_ENHANCEMENT.md | 225 ++++++++ dongle-smartcontract/src/project_registry.rs | 8 + dongle-smartcontract/src/review_registry.rs | 6 + dongle-smartcontract/src/tests/mod.rs | 1 + .../src/tests/optional_field_validation.rs | 318 ++++++++++++ dongle-smartcontract/src/utils.rs | 121 ++++- 11 files changed, 2633 insertions(+), 3 deletions(-) create mode 100644 CHANGELOG.md create mode 100644 CODE_CHANGES.md create mode 100644 IMPLEMENTATION_SUMMARY.md create mode 100644 IMPLEMENTATION_VERIFICATION.md create mode 100644 QUICK_REFERENCE.md create mode 100644 VALIDATION_ENHANCEMENT.md create mode 100644 dongle-smartcontract/src/tests/optional_field_validation.rs diff --git a/CHANGELOG.md b/CHANGELOG.md new file mode 100644 index 0000000..5089dad --- /dev/null +++ b/CHANGELOG.md @@ -0,0 +1,317 @@ +# Changelog - Optional Fields Validation Enhancement + +## Version: 0.2.0 +**Date:** 2026-04-28 +**Type:** Enhancement +**Priority:** Medium + +--- + +## Summary + +This release implements comprehensive validation for optional fields in the Dongle smart contract.

None values are always valid. + +**Q: What error is returned on validation failure?** +A: `ContractError::InvalidProjectData` is returned for all optional field validation failures. + +**Q: Can I use these functions outside of registration/update?** +A: Yes! The validation functions are public and can be called from anywhere in the contract. + +**Q: Do I need to call validation functions manually?** +A: No. If you use `ProjectRegistry::register_project()`, `ProjectRegistry::update_project()`, `ReviewRegistry::add_review()`, or `ReviewRegistry::update_review()`, validation is automatic. + +**Q: What's the performance impact?** +A: Negligible. Validation is O(n) where n is the string length, which is bounded by MAX_WEBSITE_LEN (256) or MAX_CID_LEN (128). + +**Q: Are there any breaking changes?** +A: No. The changes are fully backwards compatible.
