Automatic memory management for opaque types [#49565]
* glib/Opaque.cs (Owned): new property saying whether or not gtk#
owns the memory.
(Opaque): Set Owned to true in the void ctor and false in the
IntPtr one.
(GetOpaque): add a new overload that can also create opaques, a la
GLib.Object.GetObject.
(Ref, Unref, Free): empty virtual methods to be overridden by
subclasses.
(set_Raw): Unref() and possibly Free() the old value, Ref() the
new one.
(~Opaque, Dispose): set Raw to IntPtr.Zero (triggering Free/Unref
if needed)
* parser/gapi2xml.pl (addReturnElem): if the method is named Copy
and returns a pointer, set the "owned" attribute on the
return-type.
* */*-api.raw: Regen
* generator/HandleBase.cs (FromNative): Add new
FromNative/FromNativeReturn overloads that takes a "bool owned"
param. Implement the 1-arg FromNative and FromNativeReturn in
terms of that.
* generator/ObjectBase.cs (FromNative): Implement HandleBase's new
overload. Use the two-arg version of GLib.Object.GetObject when
"owned" is true.
* generator/OpaqueGen.cs (Generate): Pull out Ref, Unref, and
Free/Destroy/Dispose methods and handle them specially by
overriding Opaque.Ref, .Unref, and .Free appropriately. (If any
of the methods are marked deprecated, output a deprecated
do-nothing method as well, to save us from having to write all
those deprecated methods by hand.)
(FromNative): use GetOpaque, passing "owned".
* generator/ReturnValue.cs (FromNative): if the value is a
HandleBase, pass Owned to its FromNative().
* generator/Parameters.cs (Owned): new property (for use on out
params)
(FromNative): Call FromNative() on the generatable, handling Owned
in the case of HandleBase.
* generator/ManagedCallString.cs:
* generator/MethodBody.cs:
* generator/Signal.cs: use param.FromNative() rather than
param.Generatable.FromNative(), to get ownership right.
* */*.metadata: Mark opaque ref/unref/free methods deprecated
(except where we were hiding them before). Add "owned" attributes
to return values and out params as needed.
* pango/AttrIterator.custom (GetFont): work around a
memory-management oddity of the underlying method.
* pango/AttrFontDesc.cs (AttrFontDesc): copy the passed-in
FontDescriptor, since the attribute will assume ownership of it.
* gtk/TreeView.custom (GetPathAtPos): set the "owned" flag on the
returned TreePaths.
* gtk/TargetList.custom: Remove refcounting stuff, which is
now handled automatically
* gtk/NodeStore.cs (GetPath): clear the Owned flag on the created
TreePath so that the underlying structure doesn't get freed when
the function returns
* gtkhtml/HTMLStream.custom (Destroy): hide this and then
reimplement it by hand to keep OpaqueGen from using it in
Dispose(), since calling it after an HTMLStream.Close() will
result in a crash.

new one.

if needed)

FromNative/FromNativeReturn overloads that takes a "bool owned"

do-nothing method as well, to save us from having to write all

in the case of HandleBase.
