Tracks template, partial, and data file dependencies during rendering to enable incremental builds. Records dependencies in BuildCache for change detection and selective rebuilding. Key Concepts: Dependency tracking: Template and data file dependencies per page Thread-safe tracking: Thread-local storage for parallel rendering Cache integration: Dependencies stored in BuildCache Incremental builds: Dependency changes trigger selective rebuilds Related Modules: bengal.cache.build_cache: Build cache persistence bengal.orchestration.incremental: Incremental build logic bengal.rendering.pipeline: Rendering pipeline using dependency tracking See Also: bengal/cache/dependency_tracker.py: DependencyTracker for tracking logic plan/active/rfc-incremental-builds.md: Incremental build design View source 2 Classes Classes CacheInvalidator Cache invalidation logic for incremental builds.

Provides methods for selective invalidation and full cache invalidation. Creation: Direct instantiation: CacheInvalidator(config_hash, content_paths, template_paths) Created by DependencyTracker for cache invalidation Requires config hash and path lists Attributes Name Type Description config_hash — Hash of configuration for config change detection content_paths — List of content file paths template_paths — List of template file paths invalidated — Set of invalidated paths Relationships — Used by: DependencyTracker for cache invalidation - Uses: Path sets for invalidation tracking Methods 4 Tag is_stale property Invariant: Check if cache needs rebuild. bool Caret Right def is_stale(self) -> bool Invariant: Check if cache needs rebuild. Returns bool invalidate_content Invalidate on content changes. 1 set[Path] Caret Right def invalidate_content(self, changed_paths: set[Path]) -> set[Path] Invalidate on content changes. Parameters 1 changed_paths set[Path] Returns set[Path] invalidate_templates Invalidate dependent pages on template changes. 1 set[Path] Caret Right def invalidate_templates(self, changed_paths: set[Path]) -> set[Path] Invalidate dependent pages on template changes. Parameters 1 changed_paths set[Path] Returns set[Path] invalidate_config Full invalidation on config change. 0 set[Path] Caret Right def invalidate_config(self) -> set[Path] Full invalidation on config change. Returns set[Path] Internal Methods 1 Caret Right __init__ 3 None Caret Right def __init__(self, config_hash: str, content_paths: list[Path], template_paths: list[Path]) Parameters 3 config_hash str content_paths list[Path] template_paths list[Path] DependencyTracker Tracks dependencies between pages and their templates, partials, and config files.

Records template and data file dependencies during rendering to enable incremental builds. Uses thread-local storage for thread-safe parallel rendering and maintains dependency graphs for change detection. Creation: Direct instantiation: DependencyTracker(cache, site=None) Created by IncrementalOrchestrator for dependency tracking Requires BuildCache instance for dependency storage Attributes Name Type Description cache — BuildCache instance for dependency storage site — Optional Site instance for config path access logger — Logger instance for dependency tracking events tracked_files — Mapping of file paths to page paths dependencies — Forward dependency graph (page → dependencies) reverse_dependencies — Reverse dependency graph (dependency → pages) current_page — Thread-local current page being processed invalidator — CacheInvalidator for cache invalidation Relationships — Uses: BuildCache for dependency persistence - Used by: RenderingPipeline for dependency tracking during rendering - Used by: IncrementalOrchestrator for change detection Thread Safety: Thread-safe. Uses thread-local storage for current page tracking and thread-safe locks for dependency graph updates. Methods 10 start_page Mark the start of processing a page (thread-safe). 1 None Caret Right def start_page(self, page_path: Path) -> None Mark the start of processing a page (thread-safe). Parameters 1 page_path Path Path to the page being processed track_template Record that the current page depends on a template (thread-safe). 1 None Caret Right def track_template(self, template_path: Path) -> None Record that the current page depends on a template (thread-safe). Parameters 1 template_path Path Path to the template file track_partial Record that the current page depends on a partial/include (thread-safe). 1 None Caret Right def track_partial(self, partial_path: Path) -> None Record that the current page depends on a partial/include (thread-safe). Parameters 1 partial_path Path Path to the partial file track_config Record that the current page depends on the config file (thread-safe). All page… 1 None Caret Right def track_config(self, config_path: Path) -> None Record that the current page depends on the config file (thread-safe). All pages depend on config, so this marks it as a global dependency. Parameters 1 config_path Path Path to the config file track_asset Record an asset file (for cache invalidation). 1 None Caret Right def track_asset(self, asset_path: Path) -> None Record an asset file (for cache invalidation). Parameters 1 asset_path Path Path to the asset file track_taxonomy Record taxonomy (tags/categories) dependencies. When a page's tags change, tag… 2 None Caret Right def track_taxonomy(self, page_path: Path, tags: set[str]) -> None Record taxonomy (tags/categories) dependencies. When a page's tags change, tag pages need to be regenerated. Parameters 2 page_path Path Path to the page tags set[str] Set of tags/categories for this page end_page Mark the end of processing a page (thread-safe). 0 None Caret Right def end_page(self) -> None Mark the end of processing a page (thread-safe). get_changed_files Get all files that have changed since the last build. 1 set[Path] Caret Right def get_changed_files(self, root_path: Path) -> set[Path] Get all files that have changed since the last build. Parameters 1 root_path Path Root path of the site Returns set[Path] — Set of paths that have changed find_new_files Find files that are new (not in cache). 1 set[Path] Caret Right def find_new_files(self, current_files: set[Path]) -> set[Path] Find files that are new (not in cache). Parameters 1 current_files set[Path] Set of current file paths Returns set[Path] — Set of new file paths find_deleted_files Find files that were deleted (in cache but not on disk). 1 set[Path] Caret Right def find_deleted_files(self, current_files: set[Path]) -> set[Path] Find files that were deleted (in cache but not on disk). Parameters 1 current_files set[Path] Set of current file paths Returns set[Path] — Set of deleted file paths Internal Methods 2 Caret Right __init__ Initialize the dependency tracker. 2 None Caret Right def __init__(self, cache: BuildCache, site: Site | None = None) -> None Initialize the dependency tracker. Parameters 2 cache BuildCache BuildCache instance to store dependencies in site Site | None Optional Site instance to get config path from _hash_config Hash config for invalidation. 0 str Caret Right def _hash_config(self) -> str Hash config for invalidation.
