a constructor or a ref, unref, or destroy method, then it must be
a reference type, so mark it "opaque" but then also mark all of
its fields public and writable.
* */*-api*.raw: Regen
* generator/Parser.cs (ParseNamespace): make the opaque attribute
check actually look at the value of the attribute rather than just
checking if it's there, so that you can change a struct's opaque
attribute from "true" to "false" via metadata and have that work.
* generator/BoxedGen.cs (Generate): do not generate the boxed's
"Free" method (since it's guaranteed to crash when we pass it a
stack pointer). If "Copy" is marked deprecated, create a
deprecated no-op for it, otherwise just skip it (since otherwise
it will just leak memory when we copy its result onto the stack).
* pango/Pango.metadata: deprecate Pango.Color.Copy and
Pango.Matrix.Copy. Hide some array fields in Pango.GlyphString
that we've never generated correctly. Tweak Pango.LayoutLine
fields to be the same as they used to be.
* pango/GlyphItem.custom (glyphs, item):
* pango/GlyphString.custom (Zero, New):
* pango/Item.custom (Zero, New):
* pango/LayoutRun.custom (glyphs, item): add deprecated API compat
* gdk/Gdk.metadata: undo the parser's new opaquification of
Gdk.Font; it's been deprecated since pre-gtk# times, and no one
should be using it, so there's no point in fixing it now. Fix up a
few other things to match how they used to be. Fix RgbCmap's
constructor args.
* gdk/RgbCmap.custom (Zero, New): deprecated API compat
* gdk/PangoAttrEmbossed.custom:
* gdk/PangoAttrStipple.custom (Zero, New, Attr): deprecated API
compat
(explicit operator ...): allow casting back and forth between
Pango.Attribute. (We can't usefully make them real subclasses of
Pango.Attribute, because there's no way for
Pango.Attribute.GetAttribute() to be able to dtrt with them.)
* gtk/Gtk.metadata: deprecate Gtk.Requisition.Copy,
Gtk.TextIter.Copy, and Gtk.TreeIter.Copy. Mark the return value of
TextView.DefaultAttributes as "owned". Mark TargetList's fields
private so it stays how it used to be.
* gtk/TextAttributes.custom (Zero, New): deprecated API compat
* gnomevfs/Gnomevfs.metadata: remove a bunch of opaque
declarations that the parser figures out on its own now.
* art/Art.metadata:
* glade/Glade.metadata:
* rsvg/Rsvg.metadata: un-mark everything the parser marked opaque
in these libraries, because all of the structs in question would
still be unusably broken, so the API churn would be pointless.
svn path=/trunk/gtk-sharp/; revision=48387
* 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.
