Check downloaded ReShare files against the file system

Mirrors .dataverse_verify_downloads(): confirms every file the download planned to save is present, is the size ReShare reported, and (when ReShare published an MD5 hash) matches the checksum.

Usage

.reshare_verify_downloads(files, download_to)

Arguments

files

the file table being built, with path, size, checksum, checksum_type, and downloaded columns, and optionally extracted

download_to

the folder the deposit was saved in

Value

files with downloaded corrected against the file system, plus size_on_disk and checksum_ok columns

Details

A row whose extracted count is set is exempt from both checks, for the same reason as the Dataverse case: ReShare's size and hash describe the zip as published, and that zip was deliberately never downloaded – only chosen members were, each verified against the CRC32 in the archive's own central directory as it is extracted.
