Bug 102438 – [Gtk] navigator.plugins contains too many plugin entries. First one are garbages

• Component: Platform
• Status: RESOLVED FIXED

[arno.]

Hi,
if I have 3 plugins, navigator.plugins.length will be 6
navigator.plugins[0], navigator.plugins[1] and navigator.plugins[2] will contain objets with null name, description or filename.
So, it looks like first half of navigator.plugins array contains wrong empty objects.

Of course, the test could only pass if the test system have the same number of plugins as me.

Looks good, r- with just a couple of minor comments.

If you look at PluginData::initPlugins() there's an ASSERT(m_plugins.isEmpty()) before calling this method, so I think we can just get rid of the resize(0) too, the vector will be empty always.

Hrm, it seems this could just be a pure js test in plugins/script-tests no? Look at navigator-mimeTypes-length.js for instance.
