Incorrect call with Cpanel::JSON::XS::decode #295

Open cross opened 2 years ago

cross commented 2 years ago

I am using perl 5.24.4 with Devel::Cover 1.36. For some reason, I've begun getting the following error upon starting any perl script with Devel::Cover

Can't read /..../cover_db/digests with Cpanel::JSON::XS: Usage: Cpanel::JSON::XS::decode(self, jsonstr, typesv= NULL) at ...Devel/Cover/DB/IO/JSON.pm line 35.

I am using Cpanel::JSON::XS version 4.08.

I've tried with no digests file, and what had earlier been working (perhaps with a different array of perl modules on the system) of a file containing only {}. Looking at that line in JSON.pm, it's calling it with <$fh> which looks like it should meet that, but.

This could well be an issue on my system, or how I've installed things, but I am not sure how to proceed. If this is an issue because of a newer Cpanel::JSON::XS, then maybe it's not fixable by me.

You'll need to specify DEVEL_COVER_DB_FORMAT=JSON as an environment variable for the Devel::Cover run to output the databases in a JSON compatible format. The default is Sereal as described here.

Is this still a problem?
