Some virtual methods are passed a native object that is wrapped in an
IDisposable managed object, which is then passed on to the managed
overrides. We need to dispose those objects as soon as possible,
otherwise their native counterpart will not be freed until the next
garbage collection. Requiring the overrides to dispose them would be
cumbersome and error-prone.
Those parameters will now be disposed in a finally {...} block, after
the virtual method has returned. This means that overrides should not
keep a reference to such a parameter outside of the scope of the method,
as it will be diposed when the method returns.
This change only affects Cairo.Context parameter for now, but it was
particularly needed for them, as they could happily hold on to tens of
MBs of memory until the next garbage collection.
This "Implementor" suffix was refactored recently (in commit
6cb03440c1) to be accessed via the ImplementorName property. So we
eliminate now the last occurrence of it in hardcoded form.
* generator/*.cs: Add a LogWriter class which formats warnings
consistently on the console. Supports the concept of non-fatal
validation warnings, since it doesn't rely on the unrolling of the
validation stack to associate a warning to a given type.
Main purpose was to add a non-fatal warning for missing element_type
attributes on list return values, though it results in cleaner log
output, and also updates some warning messages to be more helpful in
how to resolve them.
* glib/Global.cs: Kill the calling convention field again.
It breaks GLib 2.x compatibility in the generator and there is
probably no need to make the calling convention configurable.
* .cs, *.custom: Hardcode Cdecl calling convention instead of
using GLib's field.
svn path=/trunk/gtk-sharp/; revision=141283
* glib/Global.cs: Add a public constant field specifying the
calling convention used by GLib and depending libraries.
By now it's hardcoded to Cdecl as every non-Win32 runtime
should ignore this attribute.
* *.cs, *.custom: Use GLib.Global.CallingConvention for both
pinvokes and callbacks. Plugs a stack leak on Win32. All
pinvokes defaulted to StdCall and thus the stack was never
cleaned up.
svn path=/trunk/gtk-sharp/; revision=141175
* configure.in.in: Target .net 2.0 profile
* gapi-cdecl-insert: Kill. We are now using the UnmanagedFunctionPointerAttribute
for callbacks.
* glib/CdeclCallback: Mark obsolete.
* generator/*.cs:
* *.custom: Use [UnmanagedFunctionPointer (CallingConvention.Cdecl)] instead of
[GLib.CDeclCallback].
svn path=/trunk/gtk-sharp/; revision=137323
* generator/ReturnValue.cs: null-term array marshaling for vms.
* generator/VirtualMethod.cs: use ToNative return type in native
callbacks.
[Fixes#501294] Patch by Sebastian Dröge.
svn path=/trunk/gtk-sharp/; revision=133670
* generator/ClassField.cs: Derive from StructField.
* generator/ObjectBase.cs: Implement validation mechanism for
class structures. If the structure contains bitfields or fields
of unknown types, we cannot generate it in managed code.

cannot be generated. [Fixes#498051]
svn path=/trunk/gtk-sharp/; revision=133514
Add support for virtual methods(vm) to the generator.
* parser/gapi2xml.pl: Generate a class_struct element with
all members of the class structure. Dump the first (instance)
parameter for signal and vm elements. Bump up parser version.
* generator/GObjectVM.cs: Added. Support for GObject virtual methods.
* generator/DefaultSignalHandler.cs: Signal specific part of vm
generation.
* generator/InterfaceVM.cs: New class for interface vms.
* generator/ObjectBase.cs: Parse the class struct.
svn path=/trunk/gtk-sharp/; revision=131604
Patch from Christian Hoff with a few minor tweaks.
* generator/CallbackGen.cs: refactor to use ManagedCallString
and drop a ton of redundant, half-baked code.
* generator/ManagedCallString.cs: add Unconditional setup
method for stuff that has to happen before the try block.
Add "drop_first" concept so it can be reused by CallbackGen
which doesn't drop first params.
* generator/Signal.cs: use Unconditional method for prep.
* generator/VirtualMethod.cs: use Unconditional method for prep.
* gtk/Gtk.metadata: mark a ref param. [Fixes#394352]
svn path=/trunk/gtk-sharp/; revision=107494
* atk/Atk.metadata: markup all the Ref* methods to indicate owned refs.
* generator/ReturnValue.cs: Add owned object ToNative handling.
* generator/VirtualMethod.cs: Split ToNative call from managed method
invocation to avoid duplicate calls in null checking scenarios.
* glib/Object.cs: add OwnedHandle property for use by language binding
code which needs to pass owned refs to native methods.
svn path=/trunk/gtk-sharp/; revision=99849
* bootstrap-2.12: bump svn version
* generator/CallbackGen.cs: add dnotify support to invoker.
Store and respond with incoming UserData params. Start using
__prefixed private vars to avoid collisions with parameters,
like the 'result' params in gio.
* generator/ManagedCallString.cs: use new data/dnotify invoker
ctors.
* generator/MethodBody.cs:
* generator/Parameters.cs: don't link "out" length params to
preceding strings.
* generator/VMSignature.cs: don't require UserData to be last
param, since it can have things like error after it.
svn path=/trunk/gtk-sharp/; revision=98782
* generator/MethodBase.cs: move Name stuff from subclasses.
Check for (G|S)et<UpperCaseLetter> in new Has props.
* generator/Method.cs:
* generator/VirtualMethod.cs: refactor out Name stuff. Use
new Has(G|S)etterName props.
* pango/Pango.metadata: workaround Has/Hash collision with
the old broken getter check. [Fixes#344954]
svn path=/trunk/gtk-sharp/; revision=90458
* generator/*.cs: implement the interfaces on the adapters too.
Generate an Implementor interface for users which exposes the
methods to implement. Register based on the Implementor sub-iface.
* gtk/*Adapter.custom: custom implementations for the custom
interface members.
* gtk/TreeIter.custom: make UserData public.
* sample/TreeModelDemo.cs: sample for implementing a TreeModel
interface.
svn path=/trunk/gtk-sharp/; revision=86753
* generator/VirtualMethod.cs: refactor delegate generation into
GenerateCallback and add [CDeclCallback] which was missing.
* generator/InterfaceGen.cs: kill GenerateDelegates. They are now
generated by VirtualMethod.GenerateCallback.
svn path=/trunk/gtk-sharp/; revision=86026
* gtk/Gtk.metadata: virtual_method rules for GInterface generation.
* generator/ReturnValue.cs (ToNative): new method for the virtual
method generation.
* generator/Parameters.cs (FromNative): null guarding.
* generator/ManagedCallString.cs: rework for interface method
generation including callback and error param support.
* generator/CallbackGen.cs: Invoker support. new class that deals
with persistence of native and wrapper delegates in native to managed
callback method signatures.
* generator/VirtualMethod.cs: support for generation of interface
methods, and all the funky parameters that come with that.
* generator/InterfaceGen.cs: Fill out the adapter implementation.

to support GError outside the last parameter slot.

svn path=/trunk/gtk-sharp/; revision=85658
* generator/CallbackGen.cs : remove an old workaround that put
the native wrapper class into the implementor's *Sharp namespace.
Use new ImportSignature sig.
* generator/ImportSignature.cs : don't mangle the callback wrapper
namespace any more. Remove impl_ns ctor param and field.
* generator/MethodBase.cs : use new MethodBody and ImportSignature
ctor sigs.
* generator/MethodBody.cs : drop the impl_ns ctor param.
* generator/Signal.cs : use new ImportSignature ctor sig.
* generator/VirtualMethod.cs : use new ImportSignature ctor sig.
svn path=/trunk/gtk-sharp/; revision=46877
* generator/*.cs : refactoring of Parameters class. Added IEnumerable
to Parameters and gracefully handle elem == null instead of special
casing parms == null all over the place. Parameter logic is now Count
driven. [Fixes#71750]
svn path=/trunk/gtk-sharp/; revision=39594
new methods to allow arbitrary setup and teardown code around the
managed call. When passing a type with "complicated" marshalling
requirements as a ref or out param, first assign the value to a
temporary variable (in Setup), then pass the temp as the ref or
out param (in ToString), and then assign the new value back to the
original argument (in Finish).
* generator/Signal.cs:
* generator/SignalHandler.cs: Update to generate correct glue for
signals with "ref" or "out" params. (#70566)
* generator/VirtualMethod.cs: Update for ManagedCallString change
* generator/IGeneratable.cs: add comments explaining what each
member does
* gtk/Gtk.metadata: mark Editable.InsertText's "position" arg

* sample/Size.cs: connect to the SizeRequested event and override
it, to test/demo the changes
svn path=/trunk/gtk-sharp/; revision=37854
