#!/bin/sh

# The snapshot page hands a branch back as an archive. Every tar based format
# goes through the same motions, fetch the archive, read its headers, prove
# the compression is genuine, then unpack it and compare the files inside
# against the repository the shared setup built, so one function below
# registers those checks per format. cgit pipes each format through the
# matching compressor on the server and this test needs the same program to
# unpack, so one missing tool skips that format on both grounds at once. The
# zip format follows at the end, since unzip shares no flags with the rest.
