Richard says that if the *.done file is there, then the checksum is not

Or that is at least how I interpret his comment.
If the check is always there, why the tag?
That's not what my reading of the bitbake source says.
bitbake/lib/bb/fetch2/__init__.py contains the only references to .done files
and all it does is make sure the done file gets "touched" whenever a fetch for
the associated file occurs; it does not otherwise check for its existence.
It does two things, one is an activity marker useful for seeing whether
files are in active use and the second is for the checksum calculation
which only ever happens once after download due to the file (see
verify_checksum() in that file).
when do we create .done files? if I am in middle of download of a tar
file and I cancel it and restart it does not fetch the file again but
tried to use the corrupt file.
Is it a big build time hit if checksums are verified all the time ?
I have seen the same problem.
