During the development of a plugin, while creating a base class that is an extension of MantisPlugin, an attempt was made to implement the schema() function and at one point an attempt was made to use the plugin_get_current() function to obtain the plugin's base name. Instead of returning the base name, the function returned the plugin's name, as defined in the register() method ($this->name).

Upon further investigation, it was found that the plugin_needs_upgrade() function in its first line is executing plugin_push_current($p_plugin->name), when it should actually be plugin_push_current($p_plugin->basename);
