_check_download_dir()

Optional[str] pip._internal.operations.prepare._check_download_dir ( Link  link, str  download_dir, Optional[Hashes]  hashes, bool   warn_on_hash_mismatch = True  )

protected

Check download_dir for previously downloaded file with correct hash
If a correct file is found return its path else None

_get_prepared_distribution()

BaseDistribution pip._internal.operations.prepare._get_prepared_distribution ( InstallRequirement  req, BuildTracker  build_tracker, PackageFinder  finder, bool  build_isolation, bool  check_build_deps  )

protected

Prepare a distribution for installation.

get_file_url()

File pip._internal.operations.prepare.get_file_url	(	Link	link,
		Optional[str]	download_dir = None,
		Optional[Hashes]	hashes = None
	)

Get file and optionally check its hash.

unpack_url()

Optional[File] pip._internal.operations.prepare.unpack_url	(	Link	link,
		str	location,
		Downloader	download,
		int	verbosity,
		Optional[str]	download_dir = None,
		Optional[Hashes]	hashes = None
	)

Unpack link into location, downloading if required.

:param hashes: A Hashes object, one of whose embedded hashes must match,
    or HashMismatch will be raised. If the Hashes is empty, no matches are
    required, and unhashable types of requirements (like VCS ones, which
    would ordinarily raise HashUnsupported) are allowed.
