class BuildManager: (source)

View In Hierarchy

This class holds shared state for building a mypy program. It is used to coordinate parsing, import processing, semantic analysis and type checking. The actual build steps are carried out by dispatch(). Attributes: data_dir: Mypy data directory (contains stubs) search_paths: SearchPaths instance indicating where to look for modules modules: Mapping of module ID to MypyFile (shared by the passes) semantic_analyzer: Semantic analyzer, pass 2 all_types: Map {Expression: Type} from all modules (enabled by export_types) options: Build options missing_modules: Set of modules that could not be imported encountered so far stale_modules: Set of modules that needed to be rechecked (only used by tests) fg_deps_meta: Metadata for fine-grained dependencies caches associated with modules fg_deps: A fine-grained dependency map version_id: The current mypy version (based on commit id when possible) plugin: Active mypy plugin(s) plugins_snapshot: Snapshot of currently active user plugins (versions and hashes) old_plugins_snapshot: Plugins snapshot from previous incremental run (or None in non-incremental mode and if cache was not found) errors: Used for reporting all errors flush_errors: A function for processing errors after each SCC cache_enabled: Whether cache is being read. This is set based on options, but is disabled if fine-grained cache loading fails and after an initial fine-grained load. This doesn't determine whether we write cache files or not. quickstart_state: A cache of filename -> mtime/size/hash info used to avoid needing to hash source files when using a cache with mismatching mtimes stats: Dict with various instrumentation numbers, it is used not only for debugging, but also required for correctness, in particular to check consistency of the fine-grained dependency cache. fscache: A file system cacher ast_cache: AST cache to speed up mypy daemon

Undocumented

def add_stats(self, **kwds: Any): (source)

Undocumented

def all_imported_modules_in_file(self, file: MypyFile) -> list[tuple[int, str, int]]: (source)

Find all reachable import statements in a file. Return list of tuples (priority, module id, import line number) for all modules imported in file; lower numbers == higher priority. Can generate blocking errors on bogus relative imports.

def dump_stats(self): (source)

Undocumented

def get_stat(self, path: str) -> os.stat_result: (source)

Undocumented

def getmtime(self, path: str) -> int: (source)

Return a file's mtime; but 0 in bazel mode. (Bazel's distributed cache doesn't like filesystem metadata to end up in output files.)

def is_module(self, id: str) -> bool: (source)

Is there a file in the file system corresponding to module id?

def load_fine_grained_deps(self, id: str) -> dict[str, set[str]]: (source)

Undocumented

def log(self, *message: str): (source)

Undocumented

def log_fine_grained(self, *message: str): (source)

Undocumented

def maybe_swap_for_shadow_path(self, path: str) -> str: (source)

Undocumented

def parse_file(self, id: str, path: str, source: str, ignore_errors: bool, options: Options) -> MypyFile: (source)

Parse the source of a file with the given name. Raise CompileError if there is a parse error.

def report_file(self, file: MypyFile, type_map: dict[Expression, Type], options: Options): (source)
