dcm-processor-utils 0.0.1

A Command line tool for the dicom processor library

dcm-processor-utils

dcm-processor-utils contains the shared helper functionality used across the dcm-processor platform.

It is the lowest-level common utility package among the modules we scanned.

Role In The Bigger Picture

This module is not a user-facing runtime on its own. Its value is that it keeps duplicated low-level logic out of the higher-level packages.

It currently provides shared behavior for things like:

• device identification
• archive and file handling
• downloader/path classification logic
• constants and settings enums

Other modules depend on it so they can share the same basic contracts and helper implementations.

Main Responsibilities

1. Archive And File Helpers

The module provides the shared file and archive handling logic used by other packages.

This includes:

• zipping directories
• extracting archives
• safe archive extraction checks

2. Shared Downloader Helpers

The module now also owns the shared downloader logic for:

• path classification
• web and git download handling
• archive extraction after download
• locating dcm-processor.json
• splitting version expressions

This keeps the CLI and DB-provider modules from carrying separate copies of the same download/extraction logic.

3. Device Identity

The package provides device identity helpers used by runtime modules to identify the local machine in a stable way where possible.

4. Shared Constants

The module exports shared constant types and app setting identifiers used throughout the platform.

Key Internal Areas

• dcm_processor_utils/file_manager.py
  • zip and unzip helpers
• dcm_processor_utils/downloaders.py
  • shared downloader and path classification logic
• dcm_processor_utils/device_info.py
  • device identification helpers
• dcm_processor_utils/constants.py
  • shared settings and constant values

Dependencies On Other Modules

This package is intentionally low in the dependency graph.

It is used by:

• dcm-processor-cli
• dcm-processor-db-provider
• dcm-processor-job-scheduler
• dcm-processor-worker
• dcm-processor-service

What This Module Is Not

This package is not:

• an application runtime
• a worker
• a scheduler
• a DICOM server
• a persistence layer

It is the shared infrastructure support package for the rest of the system.

Summary

Use this module for reusable low-level behavior that should stay consistent across the platform.

It exists to reduce duplication and keep the higher-level modules aligned on common helper logic.
