Hi Loic,
> Note that you also need to update
We have prepared mSHEC's parameter sets which we think will be commonly used.
Because I'm not sure how to update another person's repository, we will write down
those parameter sets in this mail.
If we are required to do something, please let us know.
while read k m c ; do
for stripe_width in $STRIPE_WIDTHS ; do
ceph_erasure_code_non_regression --stripe-width $stripe_width --plugin shec --parameter technique=multiple --parameter k=$k --parameter m=$m --parameter c=$c $ACTION $VERBOSE $MYDIR
done
done <<EOF

Hi,
Note that you also need to update
https://github.com/dachary/ceph-erasure-code-corpus/blob/master/v0.85-764-gf3a1532/non-regression.sh
to include non regression tests for the most common cases of the SHEC plugin encoding / decoding. This is run by make check (this repository is a submodule of Ceph). It helps make sure that content encoded / decoded with a given version of the plugin can be encoded / decoded exactly in the same way by all future versions.
Cheers
