Bug 494486 – net-misc/flexget-1.1.138 with dev-python/jsonschema-2.3.0 - flexget --check: ERROR manager Task test task: expected string or buffer

• Product: Gentoo Linux
• Status: RESOLVED TEST-REQUEST

[Description Craig Andrews 2013-12-17 03:53:35 UTC]

When using net-misc/flexget with dev-python/jsonschema-2.3.0, valid configuration fails at runtime. I have reported this issue upstream in flexget at http://flexget.com/ticket/2291 Here's the problem:

In config.yml, try a block like this:

tasks:
  test task:
    rss:
      url: http://rss.thepiratebay.sx/0
      link:
        - magneturi
        - link

Then run flexget --check

The result is:

2013-11-19 15:40 ERROR    manager                       Task test task: expected string or buffer

According to http://flexget.com/wiki/Plugins/rss that should work, and it does work with dev-python/jsonschema-2.0.0.

I believe that the ebuild for net-misc/flexget should have the dependency on dev-python/jsonschema changed from:
>=dev-python/jsonschema-2.0[${PYTHON_USEDEP}]
to:
=dev-python/jsonschema-2.0[${PYTHON_USEDEP}]

in order to reflect the fact that flexget doesn't work with newer versions of jsonschema, and then when a fixed version of flexget is released the dependency expression can be changed back.

Reproducible: Always

This one looks like a bug in jsonschema as well.

[Comment 2 Pacho Ramos 2017-01-10 15:41:42 UTC]

try with jsonschema-2.5.1-r2 please
