4b94c0831e Use 'dumb quotes' rather than `really dumb quotes'
Back in the far-off twentieth century, it was normal on unix
workstations for U+0060 GRAVE ACCENT to be drawn as "‛" and for U+0027
APOSTROPHE to be drawn as "’". This led to the convention of using
them as poor-man's ‛smart quotes’ in ASCII-only text.

However, "'" is now universally drawn as a vertical line, and "`" at a
45-degree angle, making them an `odd couple' when used together.

Unfortunately, there are lots of very old strings in glib, and also
lots of new strings in which people have kept up the old tradition,
perhaps entirely unaware that it used to not look stupid.

Fix this by just using 'dumb quotes' everywhere.

f24d8247b3 Do not use static GTypeInfo and GInterfaceInfo
Either g_type_register_static_simple (used by G_DEFINE_TYPE_EXTENDED)
and G_IMPLEMENT_INTERFACE use automatic variables for GTypeInfo and
GInterfaceInfo structs, while tutorials and source code often use
static variables. This commit consistently adopts the former method.

3bd3067ffc gobject: Use _ prefixing in private headers over G_GNUC_INTERNAL in public headers
This helps out gtk-doc and g-ir-scanner, and also makes much clearer
what's private versus public.

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*.

Wed Mar  7 09:33:27 2001  Tim Janik  <timj@gtk.org>

Sat Feb 17 04:55:35 2001  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: changed collect_format, collect_value() and lcopy_format,
        lcopy_value() in the GTypeValueTable. the collect functions are now
        called only once per value, collect_format/lcopy_format are strings
        that enlist all necessary GTypeCValues to be varargs-collected.

        * gvalue.h: ranamed STATIC_TAG to G_VALUE_NOCOPY_CONTENTS to indicate that
        a value shouldn't copy its contents.

        * gvaluecollector.h: changed G_VALUE_COLLECT() and G_VALUE_LCOPY()
        macros to carry an additional argument (flags) that can be used
        to pass G_VALUE_NOCOPY_CONTENTS along to the collection functions.

        * *.c: adapted collect_value() and lcopy_value() functions to the new
        prototypes, support G_VALUE_NOCOPY_CONTENTS where apropriate.

        * gsignal.[hc]: introduced a G_SIGNAL_TYPE_STATIC_SCOPE flag that can
        be passed along (ORed) with the parameter types, indicating that the
        emission arguments are to be considered static for the scope of the
        emission. should be used with care and only if the caller knows that
        a parameter cannot be destroyed/freed from signal handlers connected
        to an emission.

Wed Jan 31 07:14:22 2001  Tim Janik  <timj@gtk.org>

        * gobject/Makefile.am: adapt to work with new CVS gtk-doc, leaving the old
        rules in place caused bogus recursions. main changes:
        - add to conditionalized section:
          all-local:

          +     cd $(srcdir) && rm -rf sgml html $(DOC_MODULE)-decl-list.txt $(DOC_MODULE)-decl.txt $(DOC_STAMPS)

        * glib/Makefile.am (maintainer-clean-local): dito.

Wed Jan 31 06:21:32 2001  Tim Janik  <timj@gtk.org>

        * gobject/tmpl/types.sgml: applied docu patch from Eric Lemings
        <eric.b.lemings@lmco.com>, did some more editing.

Wed Jan 31 06:19:49 2001  Tim Janik  <timj@gtk.org>

        * gparam.h: gtk-doc sucks for not dealing with #define inside enums.

        * gtype.[hc]: added G_TYPE_FLAG_RESERVED_ID_BIT, a bit in the type
        number that's supposed to be left untouched (preserved mainly
        for the signal code).

        * *.c: added thread safety code, based on an old patch from sebastian.
        the remaining thread safety issues are now datalists on pspecs (to be
        solved im gdataset.c) and gvalue.c where locking concerns value exchange
        functionality only, and that's soon to be revised.

Wed Oct 25 20:27:02 2000  Tim Janik  <timj@gtk.org>

        * gtype.c (g_type_free_instance): for the moment, freeing object
        structures will fill their memory portion with 0xAA. there's a
        FIXME there, remove this line at a later point.

Tue Oct 24 23:10:26 2000  Tim Janik  <timj@gtk.org>

        * glib-genmarshal.1:
        * glib-genmarshal.c: added publically installed marshaller generator.

        * gtype.h: added G_TYPE_INSTANCE_GET_INTERFACE() to retrive a certain
        interface VTable from instances.

Mon Oct 23 08:28:15 2000  Tim Janik  <timj@gtk.org>

        * gobject.[hc]: new functions for closure maintenance:
        (g_object_watch_closure): maintain validity of the object and
        the closure for objects that are used as data part of a closure.
        (g_cclosure_new_object): convenience function to create C closures
        that have an object as data argument.
        (g_closure_new_object): convenience function to create closures
        that have an object as data argument.

        * gclosure.[hc]: implementation of GClosure mechanism.
        a closure is basically an encapsulation of a callback function
        and its environment. ideally, most places supporting callback
        functions will simply take a GClosure* pointer and thus unify
        callback environments wrg destroy notification etc.
        GClosure provides destroy notifiers for arbitrary data pointers,
        reference counting, invalidation notification (it can be invalidated
        which is merely a deactivate state) and a marshallinbg abstraction.
        GCClosure is also provided in these files, they present a specialized
        GClosure implementation for C language callbacks.

        * genum.c: macro cleanups.

        * gboxed.[hc]: new files, for boxed type abstraction.
        (g_boxed_copy): copy a boxed structure
        (g_boxed_free): free a boxed structure
        (g_value_set_boxed):
        (g_value_get_boxed): standard GValue functions for boxed types
        (g_boxed_type_register_static): convenience function for easy
        introduction of new G_TYPE_BOXED derivatives.

        * gparam.[hc]: introduced g_param_type_register_static(), a short hand
        for creation of new GParamSpec derived types.

        * gtype.[hc]: many fixes, introduced ability to flag individual
        type nodes as ABSTRACT upon registration, added value_peek_pointer()
        to the value table to peek at GValue contents as a pointer for types
        that support this. fixed up GValue checks.

        * gvalue.[hc]: added g_value_fits_pointer() and g_value_get_as_pointer()
        to peek at the value contents as pointer.

        * *.[hc]: adaptions to type macro fixes and changes in the type
        registration API.

        * many const corrections over the place.

Sat Oct 21 02:49:56 2000  Tim Janik  <timj@gtk.org>

        * gtype.c (g_type_conforms_to): this function basically behaves like
        and is_a check, except that it _additionally_ features interfaces
        for instantiatable types. enforce this in the second branch as well
        (`type' conforms_to `type') even if `type' is not an interface type.

Fri Oct 20 15:31:04 2000  Tim Janik  <timj@gtk.org>

        * gvaluetypes.[hc]: added G_TYPE_POINTER implementation from jrb.

        * gtype.[hc]:
        * gobject.c:
        * gvaluetypes.c: added GTypeValueTable.value_peek_pointer and
        suitable implementations of this for G_TYPE_STRING, G_TYPE_OBJECT
        and G_TYPE_POINTER.

Mon Aug 21 04:13:37 2000  Tim Janik  <timj@gtk.org>

        * gbsearcharray.[hc]: long standing needed generic implementation
        of a binary searchable, sorted and dynamically sized array.

Fri Jun 23 17:20:26 2000  Tim Janik  <timj@gtk.org>

        * glib.h: define gstring in terms of gchar*. this typedef reflects
        the type name of the primitive G_TYPE_STRING in the gobject module.

Sat Jun 24 23:03:04 2000  Tim Janik  <timj@gtk.org>

        * gtype.[hc]: provide G_TYPE_CHAR, G_TYPE_UCHAR, G_TYPE_BOOLEAN,
        G_TYPE_INT, G_TYPE_UINT, G_TYPE_LONG, G_TYPE_ULONG, G_TYPE_FLOAT,
        G_TYPE_DOUBLE and G_TYPE_STRING fundamental types.
        added a GTypeValueTable* pointer to GTypeInfo structure for types
        to implement GValue handling functions.
        GTypeValueTable contains the following members:
          value_init(): initialize a GValue structure.
          value_free(): free GValue structure contents (optional).
          value_copy(): copy one GValue contents to another GValue structure of
          collect_type: varargs collection type for the first variable argument
          to be collected by collect_value().
          collect_value(): variable arguments collection function (optional).
          lcopy_type: varargs collection type for the first variable argument
          to be location copyied by lcopy_value().
          lcopy_value(): variable arguments location copy function (optional).
        g_type_value_table_peek(): new function to retrive the GTypeValueTable*
        for a type node. ValueTables get inherited from parent types, unless
        overridden through the GTypeInfo structure. internally, GTypeValueTable
        support means an added overhead of one pointer per static or used
        dynamic type node.
        g_type_add_class_cache_func(): provide a cache_func/data pair to be
        called  prior to a type nodes last_unref() function, this can be used
        to prevent premature class destruction. multiple installed cache_func()
        will be chained upon last_unref() untill one of them returns TRUE.
        the cache_func()s have to check the type id passed in to figure whether
        they actually wants to cache the class of this type (since any types are
        routed through the cache_func() chain).
        g_type_remove_class_cache_func(): remove a previously installed
        cache_func/data pair. the cache maintained by this function has to be
        clear when calling g_type_remove_class_cache_func() to avoid leaks.
        g_type_class_unref_uncached(): class unref function for cache_func()
        implementations, unreferences a class omitting the cache chain (and
        therefore unref->cache->unref->... loops).

        * gvaluetypes.[hc]: provide the value setters/getters for the primitive
        fundamental types boolean, char, uchar, int, uint, long, ulong, float,
        double and string.

        * gvalue.[hc]: provide G_TYPE_IS_VALUE() in terms of whether a
        GTypeValueTable is provided for this type.
        removed g_value_init_default(), g_value_validate(), g_value_defaults(),
        g_value_set_default() and g_values_cmp() as these are supplied by the
        GParamSpec API now.
        moved g_values_exchange() into the "implementation details" section,
        since it just provides the underlying functionality for
        g_value_convert().

        * gvaluecollector.h: renamed the varargs value container from
        GParamCValue to GTypeCValue as the value collection methods are
        supplied by the type system now.
        G_PARAM_COLLECT_VALUE() and G_PARAM_LCOPY_VALUE() got renamed to
        G_VALUE_COLLECT() and G_VALUE_LCOPY() and operate without a
        GParamSpec structure now.

        * genums.h: macros cleanups/fixes.

        * genum.c: provide G_TYPE_ENUM and G_TYPE_FLAGS type
        and assorted g_value_{s|g}et_{enum|flags}() implementations.

        * gobject.[hc]:
        provide G_IS_VALUE_OBJECT(), G_TYPE_OBJECT ValueTable methods
        and g_value_{s|g}et_object().

        * gparam.[hc]: reduced class to value_set_default(),
        value_validate() and values_cmp(). also parameters now need to fill
        in a GType value_type; field to indicate the GValue type they
        are handling. provide g_param_value_set_default(),
        g_param_value_defaults(), g_param_value_validate() and
        g_param_values_cmp().

        * gparamspecs.[hc]: got rid of the g_value_* functions and
        the G_IS_VALUE_* macros. adapted param spec implementations
        according to the GParamSpecClass changes.

397ad5881e add reserved fundamental ids for gtk types (for transition time). added
Fri May  5 01:15:48 2000  Tim Janik  <timj@gtk.org>

	* gtype.h: add reserved fundamental ids for gtk types (for transition
	time). added G_TYPE_FUNDAMENTAL_MAX for gtk.

Mon Apr 17 20:45:50 2000  Tim Janik  <timj@gtk.org>

	* glib-gobject.c (g_object_base_class_finalize): oops, don't unset
	n_params prior to destructing them.

Tue Apr 11 04:28:10 2000  Tim Janik  <timj@gtk.org>

	* fixed a couple of bugs in the initial parameter/object
	implementations, after getting beast running on GObject and GValue.

Fri Apr  7 04:27:49 2000  Tim Janik  <timj@gtk.org>

	* glib-gobject.[hc]: completed parameter set/get implementations,
	along with asyncronous parameter changed notification queue.

Sun Apr  2 04:54:36 2000  Tim Janik  <timj@gtk.org>

	* glib-gobject.[hc]: GObject implementation, that is facilities
	for setting/getting quarked data and reference counting.

	* glib-gparamspecs.[hc]: first actuall parameter implementations
	for GLib, so far we have: char, uchar, bool, int, uint, long,
	ulong, enum, flags, float, double, string and object. each of these
	GParamSpecs is a new instantiatable type in its own respect,
	so the .c file derives 13 new types from G_TYPE_PARAM and
	defines over 50 (*2) conversion facilities.

	* glib-gvaluecollector.h: generic varargs handling stubs for
	GParamSpecs, private header file (does get installed for
	inclusion into user code though).

	* glib-gvalue.[hc]: GValue functionality implementation.

	* glib-gparam.[hc]: basis GParamSpec implementation for
	the virtual base type G_TYPE_PARAM.

        * glib-genums.[hc]: enum/flags type implementation, based on
	bseenum.[hc].

	* glib-extra.[hc]: GLib additions, including 1.3 compatibility
	routines and various other functions, from string manipulation
	over list manipulation up to a unix signal GSource.

	* glib-gtype.[hc]: GLib Type System implementation, heavily
	based on BSE's dynamic type system.
