- Introduced a series of planning documents detailing the Redb-based IPS index design, schema specification, and encoding strategies.
- Added a high-level overview of the core search index schema and the use of Redb MVCC transactions for consistency and performance improvements.
- Documented simplified schema definitions avoiding optional elements, focusing on compact encodings.
- Defined transitions to postcard-encoded binary formats, aligning with Rust’s serde for standardized serialization.
- Outlined migration strategies, invariants, error handling, and testing plans for index adoption.
- Enhanced documentation with structured explanations for developers to implement, extend, and migrate seamlessly to the new index model.
- Introduced `api.rs` to provide a stable, struct-first API surface for building, linting, resolving, and publishing IPS packages.
- Encapsulated existing functionality for better abstraction and usability in external integrations.
- Enhanced `libips` with a high-level repository and transaction interface.
- Added support for dependency generation, manifest transformations, and linting via configurable rulesets.
- Updated documentation with integration flow examples and usage guidelines.
- Introduced `depend.rs` to handle dependency generation for ELF files, scripts, Python modules, and SMF manifests.
- Implemented file classification and analysis logic with configurable bypass rules and runpath handling.
- Added utility functions to resolve file dependencies into manifest actions using a provided repository.
- Updated `Cargo.toml` with `goblin` dependency for ELF processing.
- Enhanced codebase with default runpath insertion, dynamic token expansion, and Python module import detection.
- Included `pkgdepend` documentation for dependency resolution overview.
- Create `pub.p5i` files during publisher addition and transaction commits to maintain compatibility with older IPS versions.
- Introduce `create_pub_p5i_file` method in `FileBackend` for generating structured `pub.p5i` JSON files.
- Update `add_publisher` and `Transaction::commit` methods to handle `pub.p5i` creation logic.
- Add tests to verify `pub.p5i` file generation in various scenarios.
- Introduce `NULL_HASH` constant to indicate the absence of original manifest storage.
- Add `new_with_null_hash` method to create metadata for obsoleted packages without storing full manifests.
- Implement on-the-fly generation of minimal manifests with obsoletion attributes for packages with null hash.
- Update `pkg5_import` to use null hash for obsoleted packages, reducing storage requirements.
- Document null hash usage and its benefits in `obsoleted_packages.md`.
- Add `obsoleted.rs` module to handle storing, metadata management, and operations for obsoleted packages.
- Implement commands for marking, listing, searching, restoring, exporting, and importing obsoleted packages (`pkg6repo`).
- Enhance `RepositoryError` with `From` implementations for various error types to manage database and serialization-related errors.
- Introduce reusable data structures for obsoleted package metadata and export representation.
- Update `Cargo.toml` and `Cargo.lock` to include new dependencies (`redb`, `bincode`, etc.).
- Document obsoleted package workflow and integration details in `doc/obsoleted_packages.md` for contributors.
- Refactor repository internals to integrate obsoleted package support without disrupting existing workflow.
- Add robust error handling, logging, and pagination for enhanced usability and scalability.
