/* GObject - GLib Type, Object, Parameter and Signal Library
changed prototype of g_boxed_type_register_static() to contain an optional Wed Mar 7 09:36:33 2001 Tim Janik <timj@gtk.org> * gboxed.[hc]: changed prototype of g_boxed_type_register_static() to contain an optional init function and a hint at whether the boxed structure uses ref counting internally. added g_value_set_boxed_take_ownership(). made G_TYPE_BOXED an abstract value type. * genums.[hc]: made G_TYPE_ENUM and G_TYPE_FLAGS abstract value types. * glib-genmarshal.c: argument type changes, preparation for third-party arg specification. * gobject.[hc]: cleaned up get/set property code. added g_strdup_value_contents() to improve warnings. * gparam.[hc]: added g_param_value_convert(), taking over responsibility of the old g_value_convert(). added G_PARAM_LAX_VALIDATION flag so validation alterations may be valid a part of the property setting process. * gparamspecs.[hc]: made value comparisons stable (for sort applications). added GParamSpecValueArray, a param spec for value arrays and GParamSpecClosure. nuked the value exchange functions and GParamSpecCCallback. * gtype.[hc]: catch unintialized usages of the type system with g_return_val_if_uninitialized(). introduced G_TYPE_FLAG_VALUE_ABSTRACT to flag types that introduce a value table, but can't be used for g_value_init(). cleaned up reserved type ids. * gvalue.[hc]: code cleanups and saner checking. nuked the value exchange API. implemented value transformations, we can't really "convert" values, rather transforms are an anylogy to C casts, real conversions need a param spec for validation, which is why g_param_value_convert() does real conversions now. * gvaluearray.[hc]: new files that implement a GValueArray, a struct that can hold inhomogeneous arrays of value (to that extend that it also allowes undefined values, i.e. G_VALUE_TYPE(value)==0). this is exposed to the type system as a boxed type. * gvaluetransform.c: new file implementing most of the former value exchange functions as single-sided transformations. * gvaluetypes.[hc]: nuked G_TYPE_CCALLBACK, added g_value_set_string_take_ownership(). * *.h: s/G_IS_VALUE_/G_VALUE_HOLDS_/. * *.[hc]: many fixes and cleanups. * many warning improvements. Tue Feb 27 18:35:15 2001 Tim Janik <timj@gtk.org> * gobject.c (g_object_get_valist): urg, pass G_VALUE_NOCOPY_CONTENTS into G_VALUE_LCOPY(), this needs proper documenting. * gparam.c: fixed G_PARAM_USER_MASK. * gtype.c (type_data_make_W): (type_data_last_unref_Wm): fixed invalid memory freeing. * gobject.c (g_object_last_unref): destroy signal handlers associated with object, right before finalization. * gsignal.c (g_signal_parse_name): catch destroyed nodes or signals that don't actually support details. * gobject.[hc]: got rid of property trailers. nuked GObject properties "data" and the "signal" variants. (g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming. Wed Mar 7 09:33:27 2001 Tim Janik <timj@gtk.org> * gobject/Makefile.am: shuffled rules to avoid excessive rebuilds. * gobject/gobject-sections.txt: updates. * gobject/tmpl/*: bunch of updates, added another patch from Eric Lemings <eric.b.lemings@lmco.com>.

/**
* SECTION:gclosure
* @short_description: Functions as first-class objects
* @title: Closures
*
* A #GClosure represents a callback supplied by the programmer.
*
* It will generally comprise a function of some kind and a marshaller
2014-07-06 03:27:58 +02:00
* used to call it. It is the responsibility of the marshaller to
* convert the arguments for the invocation from #GValues into
* a suitable form, perform the callback on the converted arguments,
* and transform the return value back into a #GValue.
*
* In the case of C programs, a closure usually just holds a pointer
* to a function and maybe a data argument, and the marshaller
* converts between #GValue and native C types. The GObject
* library provides the #GCClosure type for this purpose. Bindings for
* other languages need marshallers which convert between #GValues
* and suitable representations in the runtime of the language in
* order to use functions written in that language as callbacks. Use
* g_closure_set_marshal() to set the marshaller on such a custom
* closure implementation.
*
* Within GObject, closures play an important role in the
* implementation of signals. When a signal is registered, the
* @c_marshaller argument to g_signal_new() specifies the default C
* marshaller for any closure which is connected to this
* signal. GObject provides a number of C marshallers for this
* purpose, see the g_cclosure_marshal_*() functions. Additional C
* marshallers can be generated with the [glib-genmarshal][glib-genmarshal]
* utility. Closures can be explicitly connected to signals with
* g_signal_connect_closure(), but it usually more convenient to let
* GObject create a closure automatically by using one of the
* g_signal_connect_*() functions which take a callback function/user
* data pair.
*
* Using closures has a number of important advantages over a simple
* callback function/data pointer combination:
*
* - Closures allow the callee to get the types of the callback parameters,
* which means that language bindings don't have to write individual glue
* for each callback type.
*
* - The reference counting of #GClosure makes it easy to handle reentrancy
* right; if a callback is removed while it is being invoked, the closure
* and its parameters won't be freed until the invocation finishes.
*
* - g_closure_invalidate() and invalidation notifiers allow callbacks to be
* automatically removed when the objects they point to go away.

/**
* g_closure_sink:
* @closure: #GClosure to decrement the initial reference count on, if it's
* still being held
*
* Takes over the initial ownership of a closure.
*
* Each closure is initially created in a "floating" state, which means
* that the initial reference count is not owned by any caller.
*
* This function checks to see if the object is still floating, and if so,
* unsets the floating state and decreases the reference count. If the
* closure is not floating, g_closure_sink() does nothing.
*
* The reason for the existence of the floating state is to prevent
* cumbersome code sequences like:
*
* |[<!-- language="C" -->
* closure = g_cclosure_new (cb_func, cb_data);
* g_source_set_closure (source, closure);
* g_closure_unref (closure); // GObject doesn't really need this
* ]|
*
* Because g_source_set_closure() (and similar functions) take ownership of the
* initial reference count, if it is unowned, we instead can write:
*
* |[<!-- language="C" -->
* g_source_set_closure (source, g_cclosure_new (cb_func, cb_data));
* ]|
*
* Generally, this function is used together with g_closure_ref(). An example
* of storing a closure for later notification looks like:
*
* |[<!-- language="C" -->
* static GClosure *notify_closure = NULL;
* void
* foo_notify_set_closure (GClosure *closure)
* {
* if (notify_closure)
* g_closure_unref (notify_closure);
* notify_closure = closure;
* if (notify_closure)
* {
* g_closure_ref (notify_closure);
* g_closure_sink (notify_closure);
* }
* }
* ]|
*
* Because g_closure_sink() may decrement the reference count of a closure
* (if it hasn't been called on @closure yet) just like g_closure_unref(),
* g_closure_ref() should be called prior to this function.

(g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()).

(g_object_connect): new convenience function to do multiple signal connections at once. (g_object_disconnect): likewise, for disconnections. * gparam.[hc] (g_param_spec_pool_lookup): took out trailer support. * gvalue.[hc]: marked g_value_fits_pointer() and g_value_peek_pointer() as private (the latter got renamed from g_value_get_as_pointer()). Wed Mar 7 09:32:06 2001 Tim Janik <timj@gtk.org> * glib-object.h: add gvaluearray.h. * gstring.[hc]: fixup naming of g_string_sprint*. * gtypes.h: fixed GCompareDataFunc naming.

fixed dealing with collection/lcopy of NULL values. Mon Dec 11 04:44:11 2000 Tim Janik <timj@gtk.org> * gboxed.c: fixed dealing with collection/lcopy of NULL values. * gclosure.h: removed insane ramblings, added G_CALLBACK() a casting convenience macro. * Makefile.am: cleanups, marshaller generation rules. * gmarshal.[hc]: new files with GRuntime standard marshallers. * glib-genmarshal.c: fix log domain, support gruntime standard marshallers, suport G_TYPE_PARAM, come with extern "C" and #include gmarshal.h. * glib-genmarshal.1: reflect glib-genmarshal.c updates. * gobject.[hc]: implement object constructor. rework parameter changed notification queueing, we support queue freezes now and don't dispatch from an idle handler anymore. parameter->property rename hassle. implemented ::properties_changed and ::notify::* signals for property change notification (the later supports property names as details). added signal connection and named data properties. (g_signal_connect_object): new function to setup while_alive connections. (g_object_class_install_property): sink properties now, since they are initially floating. (g_object_steal_data): (g_object_set_data_full): (g_object_set_data): (g_object_get_data): set/get data by using g_datalist_*() functions directly. (g_object_queue_param_changed): nuked. (g_object_freeze_notify): start queueing of property changes (freeze/ thaw calls stack). (g_object_notify): announce changes of a certain property directly. (g_object_thaw_notify): process queue of property changes, therefore emitting GObject::notify::detail with detail being the changed properties names. (G_OBJECT_WARN_INVALID_PROPERTY_ID): saner macro variant of former G_WARN_INVALID_PARAM_ID(). * gparam.[hc]: param specs are now initially floating and need to be sunken with g_param_spec_sink(), support G_TYPE_PARAM values. added G_PARAM_CONSTRUCT and G_PARAM_CONSTRUCT_ONLY parameter flags, required by GObjectClass.constructor(). * gparamspecs.[hc]: added GParamSpecParam, GParamSpecPointer and GParamSpecCCallback, param specs for G_TYPE_PARAM, G_TYPE_POINTER and G_TYPE_CCALLBACK respectively. * gsignal.[hc]: cleanups. (signal_id_lookup): after walking the anchestry, try interfaces as well. (g_signal_new): new function to create signals from varargs type list. (g_signal_connect_closure): closure connection variant that works from signal name+detail. (g_signal_connect_data): c handler connection variant that works from signal name+detail. (g_signal_emit_valist): emit signal for an instance with paraneters collected from a va_list. (g_signal_emit): emit signal, taking parameters from varargs list. (g_signal_emit_by_name): same as g_signal_emit, working from signal name+detail. (signal_emit_R): return whether return_value needs to be altered. * gtype.[hc]: set log-domain to GRuntime, i'm slowly getting to all the points that need to reflect the upcoming rename. melt g_type_conforms_to() functionality into g_type_is_a(), as that is what we really want (liskov substitution principle). assorted changes to other files due to conforms_to->is_a. * gvalue.[hc]: implemented g_value_set_instance() that sets a value from an instantiatable type via the value_table's collect_value() function (based on an idea from James Henstridge <james@daa.com.au>). cleanups/fixes. * gvaluetypes.[hc]: implement G_TYPE_CCALLBACK and G_TYPE_PARAM.

closure: fix handling of ENUMs and integral return types on 64-bit BE platforms enums are stored in v_long but need to be marshalled as signed integers. On platforms where int is 32 bits, taking the address of v_long resulted in the wrong 32 bits being marshalled. So we need to stuff the enum's int-sized value to a temporary int-sized variable and marshall that instead. Second, on return, libffi actually returns a pointer to a value that's sized according to platform conventions, not according to what the caller requested. ie if ffi_type_sint was requested, the value can still be a 64-bit sign-extended long on a 64-bit architecture like PPC64, thus the caller cannot simply cast the return value as a pointer to the desired type, but must cast as a pointer to an integral type and then cast to the desired type to remove any sign extension complications. For more information on how to correctly handle libffi return values, see the following bug, specifically comment 35: https://bugzilla.redhat.com/show_bug.cgi?id=736489 "For 64-bit ABIs that extend integral returns types to 64-bits, libffi always returns full 64-bit values that you can truncate in the calling code. It's just the way it is has always been. Please don't change libffi. I'll document this clearly for the next version (perhaps there is a mention of this, I haven't looked yet). The same is true for returning 8-bit values, for instance, on 32-bit systems. All ABIs extend those results to the full 32-bits so you need to provide a properly aligned buffer that's big enough to hold the result." https://bugzilla.gnome.org/show_bug.cgi?id=659881

Second, on return, libffi actually returns a pointer to a value that's sized according to platform conventions, not according to what the caller requested. ie if ffi_type_sint was requested, the value can still be a 64-bit sign-extended long on a 64-bit architecture like PPC64, thus the caller cannot simply cast the return value as a pointer to the desired type, but must cast as a pointer to an integral type and then cast to the desired type to remove any sign extension complications. For more information on how to correctly handle libffi return values, see the following bug, specifically comment 35: https://bugzilla.redhat.com/show_bug.cgi?id=736489 "For 64-bit ABIs that extend integral returns types to 64-bits, libffi always returns full 64-bit values that you can truncate in the calling code. It's just the way it is has always been. Please don't change libffi. I'll document this clearly for the next version (perhaps there is a mention of this, I haven't looked yet). The same is true for returning 8-bit values, for instance, on 32-bit systems.

closure: fix handling of ENUMs and integral return types on 64-bit BE platforms enums are stored in v_long but need to be marshalled as signed integers. On platforms where int is 32 bits, taking the address of v_long resulted in the wrong 32 bits being marshalled. So we need to stuff the enum's int-sized value to a temporary int-sized variable and marshall that instead. Second, on return, libffi actually returns a pointer to a value that's sized according to platform conventions, not according to what the caller requested. ie if ffi_type_sint was requested, the value can still be a 64-bit sign-extended long on a 64-bit architecture like PPC64, thus the caller cannot simply cast the return value as a pointer to the desired type, but must cast as a pointer to an integral type and then cast to the desired type to remove any sign extension complications. For more information on how to correctly handle libffi return values, see the following bug, specifically comment 35: https://bugzilla.redhat.com/show_bug.cgi?id=736489 "For 64-bit ABIs that extend integral returns types to 64-bits, libffi always returns full 64-bit values that you can truncate in the calling code. It's just the way it is has always been. Please don't change libffi. I'll document this clearly for the next version (perhaps there is a mention of this, I haven't looked yet). The same is true for returning 8-bit values, for instance, on 32-bit systems.
