project_config.cache module

Persistent cache.

class project_config.cache.Cache[source]

Bases: object

Global cache to avoid recomputing expensive intermediate objects.

_expiration_time: float | int | None = 30

static clean() → None[source]: Remove the cache directory.

classmethod ensure_dir() → None[source]: Ensure the cache directory exists.

classmethod generate_unique_key_from_tree_entry(tree_entry: str) → str[source]: Generate a unique key.

classmethod get(tree_entry: str) → Any[source]

classmethod set(tree_entry: str, value: Any) → None[source]

classmethod set_expiration_time(expiration_time: Optional[Union[float, int]] = None) → None[source]

Configure global cache.

Parameters:: expiration_time (float) – Expiration time in seconds for cached objects.

project_config.cache.generate_possible_cache_dirs() → Iterator[str][source]: Generate the possible cache directories.

project_config.cache.get_creation_time_from_fpath(fpath: str) → int[source]: Get creation time of an entry in the cache given its path.

project_config.cache.read_file(fpath: str) → bytes[source]: Read a file from the cache.

project_config.cache.write_file(fpath: str, value: Any) → None[source]: Write a file to the cache.
