Subject: bug#70588: hash mismatch error and stop fallback
Date: Thu, 25 Apr 2024 15:28:27 +0200 [thread overview]
Message-ID: <87ttjpinb8.fsf@gmail.com> (raw)
Hi,
Considering something from the past – well to my knowledge it is still
an issue with the current implementation and such it will be a issue for
the future. ;-)
For instance, the R package MASS from 2019 (Guix revision 711cec):
because the CRAN project did some in-place replacements, we have a hash
mismatch and all the process stops.

Therefore, the bug is to not consider a hash mismatch as a fullstop and
error out but consider it as a failure of one strategy and thus try the
next strategy.
Other said, hash mismatch should be raised and obviously the content
must be discarded; then the hash mismatch should be considered as “not
found” so let try the next strategy for downloading the content.
Cheers,
simon
