Module cache

Modules§

CACHE_FORMAT_VERSION: Current cache format version. Bump this when making breaking changes to the cache format.
COMPILER_VERSION_HASH: Compiler version hash. Caches from different compiler versions are invalid.
GO_STDLIB_HASH: Go stdlib-only content hash (typedefs/*.d.lis).
PRELUDE_HASH: Prelude-only content hash (prelude.d.lis).
STDLIB_HASH: Combined stdlib content hash. Changes to any stdlib file (prelude.d.lis or any typedefs/*.d.lis) will change this hash, invalidating all user module caches.

apply_emit_stamps: Set or clear the emit_stamp for each module’s cache file. Missing files are skipped; undecodable (e.g. pre-bump) files are unlinked and skipped; other read errors propagate so the debug pre-write clear can hard-fail rather than leave a stale stamp over freshly-overwritten Go.
cache_file_name
cache_path
compute_emit_artifact_hash: Hash over the non-debug Go-artifact inputs for one module.
compute_module_hash: Compute a module’s hash from its source hash and dependency hashes. This ensures transitive invalidation: if C changes, B’s module_hash changes (even though B’s source didn’t), which invalidates A’s cache.
get_dependency_module_hashes
hash_module_sources
is_cache_disabled
is_cache_valid
register_cached_module: Register a cached module in the store. display_path for each cached file is recomputed from the project layout against the current cwd, so warm and cold builds render the same diagnostic paths even though the cache stores only bare names.
