By default, JSON::Validator::OpenAPI tries to fetch the
swagger v2 schema from http://swagger.io/v2/schema.json.
If you've installed from CPAN, JSON::Validator::OpenAPI will
come with a cached copy, so it won't try to fetch it over HTTP.
However, if you've installed from libjson-validator-perl
from Debian/Ubuntu, the Debian package excludes the cached copy,
so JSON::Validator::OpenAPI tries to fetch it over HTTP.
Unfortunately, today and other days in the past, the file at
http://swagger.io/v2/schema.json has been unavailable, and this causes
Koha to crash in a perpetual loop.
This patch includes a copy of the swagger v2 schema, and it loads
it locally rather than fetching over HTTP.
The changes to Koha/REST/Plugin/PluginRoutes.pm are not required,
since the validator isn't currently called there, but I've added
a patch to future proof it.
To Test:
0a) Remove /usr/share/perl5/JSON/Validator/cache/36d1bd12eeed51e86c8695bd8876a9df
if it exists
0b) Block external access to http://swagger.io/v2/schema.json or
test during an outage when it's unavailable
0c) Do not apply patch
1) koha-plack --restart kohadev
2) Note that it crashes in a loop and is unavailable in web browser
3) Apply patch
4) koha-plack --restart kohadev
5) Note that Koha comes up and there are no errors in the Plack logs
