_checksum_failure_temp_file(distdir,
basename)
| source code

First try to find a duplicate temp file with the same checksum and
return that filename if available. Otherwise, use mkstemp to create a new
unique filename._checksum_failure_.$RANDOM, rename the given file, and
return the new filename. In any case, filename will be renamed or removed
before this function returns a temp filename.

_check_digests(filename,
digests,
show_errors=1)
