    Description

      For the HSM migration enhancement (LU-6081), it would be nice to be able to transfer data (stripe informaton and mdt_index) between lfs and the copytool in an exchange format, namely JSON.

      The current liblustreapi_json.c can only encode JSON. Use the CCAN (Comprehensive C Archive Network) JSON which it relatively small, can encode/decode, and has a decent testsuite.

      Replace liblustreapi_json.c with the new implementation.

            [LU-6246] Add a JSON decoder

            Hi Frank. With LUG coming up I like to discuss on developer's day about using JSON in replacement of YAML. Especially since json-c seems to be the standard now.

            The licenses used by CCAN JSON are:

            • Test anything protocol - tap.c: FreeBSD license (aka 2 clauses BSD)
            • Test anything protocol - compiler.h dependency: CC0 (Creative Commons 0)
            • JSON: MIT

            All 3 licenses are GPLv2 and v3 compatible.
