A major bug in zchunk-1.1.14 was flagged up to me today. If zchunk-
1.1.14 (on a system with zstd 1.5.0+) is used to create a zck file with
a zdict, the file will be impossible to decompress. Embarrassingly,
the tests weren't testing this combination.
The good news is that this doesn't affect decompression at all, so this
is only a problem for the server that's used to generate the zchunked
metadata, which is using zdicts.
I've just finished building zchunk-1.1.15 which fixes this bug (and
adds tests to make sure it never happens again), but please make sure
that zchunk doesn't get updated to 1.1.14 on the servers that generate
the metadata.
Thanks, and apologies for the inconvenience.
Jonathan
