gedih3.doctor.parallel

Doctor-internal scandir helpers + back-compat re-export of gedih3.parallel.parallel_map().

The general parallelism primitive has been promoted to gedih3.parallel (it is used by the build, download, and manifest-writing paths too, not only by the doctor diagnoses). This module now keeps only the doctor-internal O(1) scandir helpers used by doctor/diagnoses/orphans.py and re-exports parallel_map so any external caller importing from here keeps working.

Functions

partition_is_empty(→ bool)	O(1) emptiness check via os.scandir() — no recursive glob.
list_year_dirs(→ List[str])	List immediate subdirectories of a partition directory.
year_dir_is_empty(→ bool)	O(1) parquet presence check inside one year=*/ directory.

Module Contents

gedih3.doctor.parallel.partition_is_empty(partition_dir: str) → bool

O(1) emptiness check via os.scandir() — no recursive glob.

Mirrors the build pipeline’s emptiness check at gh3builder.py:1356-1362. A partition is considered empty when it contains no parquet file at any depth (year subdir or root).

gedih3.doctor.parallel.list_year_dirs(partition_dir: str) → List[str]

List immediate subdirectories of a partition directory.

Single os.scandir call instead of glob.glob('*/'); same primitive the build pipeline uses to enumerate per-h3 work units.

gedih3.doctor.parallel.year_dir_is_empty(year_dir: str) → bool

O(1) parquet presence check inside one year=*/ directory.
