Subject: qa/cephfs: handle non-numeric values for json.loads()
X-Git-Tag: v18.1.0~1032^2
X-Git-Url: http://git-server-git.apps.pok.os.sepia.ceph.com/?a=commitdiff_plain;h=38fdf6df664e7fc28f1e381ce1bb590fc74926ae;p=ceph.git

qa/cephfs: handle non-numeric values for json.loads()

Not handling values infinity, negative infinity and "NaN" properly leads
to JSONDecodeError. Replace "inf" by "Infinity" in string before loading
JSON and pass a method to json.load() to handle these values to fix this
issue.
