Subject: [PATCH] src: Fix refcounting issues | ||
|
||
Commit 5a455b1ead attempted to fix both GLib warnings around | ||
floating references and other presumed refcounting issues. However | ||
it missed 2 kinds of bugs: | ||
|
||
- The places that take an IBusText created from a static string | ||
were made to avoid freeing it afterwards, but the staticness refers | ||
to the string content, not the object itself. | ||
- The places that are documented to emit signals on floating object | ||
references used to do the following after signal emission: | ||
|
||
if (g_object_is_floating (object)) | ||
g_object_unref (object) | ||
|
||
And did possibly trigger GLib warnings were changed to: | ||
|
||
if (g_object_is_floating (object)) | ||
g_object_sink_ref (object); | ||
g_object_unref (object); | ||
|
||
Which fixes the GLib warning for floating references, but do | ||
unintendedly steal one reference away for non floating references. | ||
|
||
This commit is essentially a revert of commit 5a455b1ead, but | ||
addressing both things differently: | ||
|
||
- All label/tooltip/symbol IBusText properties in IBusProperty do | ||
now always sink the reference of the stored object. | ||
|
||
- All places documented as maybe using objects with a floating reference | ||
on signals changed to doing: | ||
|
||
if (g_object_is_floating (object)) { | ||
g_object_ref_sink (object); | ||
g_object_unref (object); | ||
} | ||
|
||
So the floating reference is owned and unreferenced without warnings, | ||
but already owned references are left unchanged. | ||
|
||
This addresses the possible GLib warnings, fixes the possible double | ||
unrefs happening on IBusText used in signals, and fixes the missing | ||
unrefs on IBusText objects created from static strings. | ||
