Pull Requests

Many files are generated. When you draft your changes, please separate out
commits that affect:

  • Cargo.lock
  • Cargo.nix
  • flake.lock

Keeping these changes isolated in specific commits makes it much easier to pull
in your changes in parallel with other features. Maintainers may harvest your
changes. We only guarantee to preserve authorship in the git log (when we
remember to do so).

Creating pull requests

  1. Fork this repository into the personal GitHub account
  2. Select the appropriate branch, release- for stable changes, unstable
    for breaking changes
  3. Make changes on the personal fork
  4. Make a Pull Request against this repository
  5. Allow maintainers to make changes to your pull request (there's a checkbox)
  6. Once the pull request has been approved, you will be thanked and observe your
    changes applied with authorship preserved (if we remember)

Description

  • Comprehensive Nixification of cargo2nix project: Introduced multiple flake configurations (flake.nix, flake-phase1.nix, flake-phase2.nix, full-flake.nix, flake-cargo2nix.nix) for reproducible Nix-based development and builds

  • Git submodule infrastructure: Added 13 Git submodules pointing to meta-introspector forks on feature/CRQ-016-nixify branch for Rust ecosystem projects and dependencies

  • Build automation: Created comprehensive Makefile with recursive submodule management, Nix build orchestration, and automated commit/push workflows

  • Nix code formatting standardization: Reformatted multiple Nix files across overlays and examples with consistent indentation, leading comma style, and improved readability

  • Dependency updates: Updated Cargo.toml with Git-based patch dependencies, upgraded cargo-platform and toml versions, and added [patch.crates-io] section for dependency overrides

  • Bug fixes: Added handling for CfgExpr::True and CfgExpr::False variants in platform configuration; improved error messaging for missing version attributes

  • Documentation and task definitions: Added conceptual mapping between elliptic curves and build systems, comprehensive task definitions for cargo-git-manage implementation, and build failure diagnostics

  • Utility scripts: Created shell scripts for submodule processing, Nix build execution, cargo2nix executable discovery, and package introspection

  • Test and example configurations: Added simple example project with flake configuration, test flakes for Rust toolchain and time-macros validation, and template files for reproducible builds

Refactored the `cargo` override in `flake.nix` to use a clearly named
`extraCargoBuildFlags` variable. This allows for safely passing additional
arguments to the `cargo build` command in a structured and configurable way.
Updated the time-rs submodule to its latest commit, which includes
changes to flake.nix, time-macros/Cargo.toml, and a new Cargo.nix file.
Corrected the syntax for defining `extraCargoBuildFlags` within the
`cargo` override in `flake.nix`. This resolves the build error caused
by incorrect attribute set definition.

This commit introduces the `repo_manager` tool, designed to automate the forking and patching of Rust crates as Git submodules.

Key changes include:
- Added `tools/repo_manager` with its source code and configuration.
- Updated `Cargo.lock` and `Cargo.toml` to reflect new dependencies and tool.
- Modified `Makefile`, `flake-phase1.nix`, `flake.lock`, and `flake.nix` to integrate the new tool and build process.
- Added `tasks/implement_fork_and_patch_submodule.toml` to outline the task for implementing the submodule logic.
- Added `generate_gh_fork_commands.sh` to generate commands for forking repositories.
…te main.rs

The `execute_actions_plan` and `update_cargo_config` functions have been moved into their respective files:
- `src/execute-actions-plan.rs`
- `src/update-cargo-config.rs`

The `src/main.rs` file has been updated to use these new modules, resolving compilation errors related to duplicate function definitions.

Changes to `Cargo.toml` and `Cargo.lock` reflect necessary dependency updates for the successful build.
This commit introduces a granular cache invalidation mechanism for `cargo-repo-sync`
by modeling the project as a Git tree structure with nested hashes.

Key changes include:
- **`RollupLock` Enhancement:** The `RollupLock` struct has been extended to store
  granular hashes for `Cargo.toml` files, Rust source files, crates, submodules,
  and an overall project root hash. This replaces the single `last_snapshot_time`
  as the primary staleness indicator.
- **Git Tree Traversal for Hashing:** The `create_snapshot` function has been
  rewritten to strictly adhere to the Git object model. It now uses a recursive
  helper function (`traverse_git_tree`) that leverages `git2-rs` to:
    - Calculate content hashes (Git Oids) for individual files (`Cargo.toml`, `.rs`).
    - Compute composite hashes for directories (trees) based on their children.
    - Determine composite hashes for submodules, incorporating their HEAD commit,
      tree hash, and working directory status.
    - Aggregate these into composite crate hashes and a final project root hash.
- **Staleness Check Refinement:** The `run_submodule_status` function now
  utilizes the `last_snapshot_time` (with a 1-year threshold) as an initial
  check to skip the expensive `create_snapshot` process if the overall cache
  is deemed fresh. Further granular checks will be implemented in subsequent
  phases using the newly populated granular hashes.
- **Dependency Update:** Added `sha2` crate for robust hashing.

This lays the groundwork for generating reusable, granular Nix expressions
per crate and managing cargo overrides for submodules based on precise
change detection.
Adds Python scripts to:
- Parse cargo depgraph output and calculate crate layers (process_depgraph.py).
- Merge layer information with non-vendored module usage counts (merge_depgraph_data.py).
- Analyze Layer 0 modules to find the most used (analyze_layer0_usage.py).
This commit introduces the new `GenerateWorkspaces` command to the CLI,
which analyzes crate dependencies and generates a clustered workspace
structure.

Key changes include:
- Added `GenerateWorkspaces` command to `cli/args.rs`.
- Implemented the core logic for `run_generate_workspaces_command` in
  `cli/commands/generate_workspaces.rs`, including:
    - Parsing '.dot' and 'tree.txt' files for dependency analysis.
    - Grouping crates by topological layers.
    - Generating 'Cargo.toml' files for each layer's workspace,
      including '[workspace]', '[workspace.dependencies]', and
      '[patch.crates-io]' sections.
- Fixed various compilation errors across multiple files, including:
    - Missing 'use' statements.
    - Type mismatches in 'cargo_config_generator.rs'.
    - Corrected 'or_insert_auto' to 'or_insert' usage in 'toml_edit'.
    - Resolved 'non-exhaustive patterns' in 'main.rs'.
    - Made 'run_process_tt_txt_command' public and created its skeleton.

Note: A persistent error regarding "binding modifiers" in 'cli/args.rs'
remains, likely due to 'clap' compatibility with Rust 2024 edition. This
issue cannot be resolved by direct code modification.

…architecture

- Decoupled nix-generator-lib from cargo-edit-tool to break cyclic dependency.
- Introduced cargo-edit-lib to define GitAdapter and CargoMetadataProvider traits.
- Modified cargo-edit-tool to implement these new traits.
- Updated cargo_repo_sync_lib_test to use the new trait-based approach and fixed compilation errors.
- Made cargo_metadata optional in cargo-edit-tool via feature flag.
