41 | * This list, global to the library, keeps all component classes that |
42 | * have a reference to their shared library handles. It allows iteration | |
43 | * on all component classes still present when the destructor executes | |
44 | * to release the shared library handle references they might still have. | |
55bb57e0 | 45 | * |
bfa9a4be | 46 | * The list items are the component classes created with |
55bb57e0 PP |
47 | * bt_plugin_add_component_class(). They keep the shared library handle |
48 | * object created by their plugin alive so that the plugin's code is | |
49 | * not discarded when it could still be in use by living components | |
50 | * created from those component classes: | |
51 | * | |
bfa9a4be | 52 | * [component] --ref-> [component class]-> [shlib handle] |
55bb57e0 | 53 | * |
bfa9a4be | 54 | * It allows this use-case: |
55bb57e0 | 55 | * |
c8db3219 | 56 | * my_plugins = bt_plugin_find_all_from_file("/path/to/my-plugin.so"); |
55bb57e0 PP |
57 | * // instantiate components from a plugin's component classes |
58 | * // put plugins and free my_plugins here | |
59 | * // user code of instantiated components still exists | |
60 | * | |
bfa9a4be MD |
61 | * An entry is removed from this list when a component class is |
62 | * destroyed thanks to a custom destroy listener. When the entry is | |
63 | * removed, the entry is removed from the list, and we release the | |
64 | * reference on the shlib handle. Assuming the original plugin object | |
65 | * which contained some component classes is put first, when the last | |
66 | * component class is removed from this list, the shared library handle | |
67 | * object's reference count falls to zero and the shared library is | |
68 | * finally closed. | |
5cea295b PP |
69 | * |
70 | * We're not using a GLib linked list here because this destructor is | |
71 | * called after GLib's thread-specific data is destroyed, which contains | |
72 | * the allocated memory for GLib data structures (what's used by | |
73 | * g_slice_alloc()). | |
