Subject: src/plugin.c: Assert that "data_sets" is non-NULL.
X-Git-Tag: collectd-5.3.0~27
X-Git-Url: https://git.verplant.org/?a=commitdiff_plain;h=044cb79594f94632eedf24a7bbfb8e645691a6d3;p=collectd.git

src/plugin.c: Assert that "data_sets" is non-NULL.

Otherwise we might run into an assertion in the AVL tree. This can be
triggered e.g. when calling plugin_get_ds() from within a config
callback.
