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. + +BUG=https://github.com/ibus/ibus/issues/2393 +BUG=https://github.com/ibus/ibus/issues/2387 +--- + src/ibusinputcontext.c | 35 +++++++++++++++++++++-------------- + src/ibusproperty.c | 32 +++++++++++++++++--------------- + 2 files changed, 38 insertions(+), 29 deletions(-) + +diff --git a/src/ibusinputcontext.c b/src/ibusinputcontext.c +index 4b27551bd..7981de381 100644 +--- a/src/ibusinputcontext.c ++++ b/src/ibusinputcontext.c +@@ -549,9 +549,10 @@ ibus_input_context_g_signal (GDBusProxy *proxy, + g_variant_unref (variant);
