Add flexible API version boundaries There are cases when it should be possible to define at compile time what range of functions and types should be used, in order to get, or restrict, the compiler warnings for deprecated or newly added types or functions. For instance, if GLib introduces a deprecation warning on a type in version 2.32, application code can decide to specify the minimum and maximum boundary of the used API to be 2.30; when compiling against a new version of GLib, this would produce the following results: - all deprecations introduced prior to 2.32 would emit compiler warnings when used by the application code; - all deprecations introduced in 2.32 would not emit compiler warnings when used by the application code; - all new symbols introduced in 2.32 would emit a compiler warning. Using this scheme it should be possible to have fairly complex situations, like the following one: assuming that an application is compiled with: GLIB_VERSION_MIN_REQUIRED = GLIB_VERSION_2_30 GLIB_VERSION_MAX_ALLOWED = GLIB_VERSION_2_32 and a GLib header containing: void function_A (void) GLIB_DEPRECATED_IN_2_26; void function_B (void) GLIB_DEPRECATED_IN_2_28; void function_C (void) GLIB_DEPRECATED_IN_2_30; void function_D (void) GLIB_AVAILABLE_IN_2_32; void function_E (void) GLIB_AVAILABLE_IN_2_34; any application code using the above functions will get the following compiler warnings: function_A: deprecated symbol warning function_B: deprecated symbol warning function_C: no warning function_D: no warning function_E: undefined symbol warning This means that it should be possible to gradually port code towards non-deprecated API gradually, on a per-release basis. https://bugzilla.gnome.org/show_bug.cgi?id=670542

Add flexible API version boundaries There are cases when it should be possible to define at compile time what range of functions and types should be used, in order to get, or restrict, the compiler warnings for deprecated or newly added types or functions. For instance, if GLib introduces a deprecation warning on a type in version 2.32, application code can decide to specify the minimum and maximum boundary of the used API to be 2.30; when compiling against a new version of GLib, this would produce the following results: - all deprecations introduced prior to 2.32 would emit compiler warnings when used by the application code; - all deprecations introduced in 2.32 would not emit compiler warnings when used by the application code; - all new symbols introduced in 2.32 would emit a compiler warning. Using this scheme it should be possible to have fairly complex situations, like the following one: assuming that an application is compiled with: GLIB_VERSION_MIN_REQUIRED = GLIB_VERSION_2_30 GLIB_VERSION_MAX_ALLOWED = GLIB_VERSION_2_32 and a GLib header containing: void function_A (void) GLIB_DEPRECATED_IN_2_26; void function_B (void) GLIB_DEPRECATED_IN_2_28; void function_C (void) GLIB_DEPRECATED_IN_2_30; void function_D (void) GLIB_AVAILABLE_IN_2_32; void function_E (void) GLIB_AVAILABLE_IN_2_34; any application code using the above functions will get the following compiler warnings: function_A: deprecated symbol warning function_B: deprecated symbol warning function_C: no warning function_D: no warning function_E: undefined symbol warning This means that it should be possible to gradually port code towards non-deprecated API gradually, on a per-release basis. https://bugzilla.gnome.org/show_bug.cgi?id=670542

Add a new _GLIB_EXTERN macro for "extern" This macro simply evaluates the "extern" unless it has been explicitly defined to something else. All of the version macros (including the unversioned deprecation markers and GLIB_AVAILABLE_IN_ALL) now include _GLIB_EXTERN as part of their definition. G_INLINE has also been modified to use _GLIB_EXTERN where appropriate. This macro should never be used outside of the gmacros.h/gversonmacros.h headers. The effect of this patch is that "extern" has now been added to all functions declared in installed headers. Strictly speaking, this is something we should have had all along... GLIB_VAR and GOBJECT_VAR have also been modified to use _GLIB_EXTERN on non-Windows, instead of "extern" which they were using before.

Add a new _GLIB_EXTERN macro for "extern" This macro simply evaluates the "extern" unless it has been explicitly defined to something else. All of the version macros (including the unversioned deprecation markers and GLIB_AVAILABLE_IN_ALL) now include _GLIB_EXTERN as part of their definition. G_INLINE has also been modified to use _GLIB_EXTERN where appropriate. This macro should never be used outside of the gmacros.h/gversonmacros.h headers. The effect of this patch is that "extern" has now been added to all functions declared in installed headers. Strictly speaking, this is something we should have had all along... GLIB_VAR and GOBJECT_VAR have also been modified to use _GLIB_EXTERN on non-Windows, instead of "extern" which they were using before. The eventual goal is to use the normal version/deprecation macros on exported variables and drop GLIB_VAR but we need to see how this will work on Windows before we go ahead with that. https://bugzilla.gnome.org/show_bug.cgi?id=688681

Add flexible API version boundaries There are cases when it should be possible to define at compile time what range of functions and types should be used, in order to get, or restrict, the compiler warnings for deprecated or newly added types or functions. For instance, if GLib introduces a deprecation warning on a type in version 2.32, application code can decide to specify the minimum and maximum boundary of the used API to be 2.30; when compiling against a new version of GLib, this would produce the following results: - all deprecations introduced prior to 2.32 would emit compiler warnings when used by the application code; - all deprecations introduced in 2.32 would not emit compiler warnings when used by the application code; - all new symbols introduced in 2.32 would emit a compiler warning. Using this scheme it should be possible to have fairly complex situations, like the following one: assuming that an application is compiled with: GLIB_VERSION_MIN_REQUIRED = GLIB_VERSION_2_30 GLIB_VERSION_MAX_ALLOWED = GLIB_VERSION_2_32 and a GLib header containing: void function_A (void) GLIB_DEPRECATED_IN_2_26; void function_B (void) GLIB_DEPRECATED_IN_2_28; void function_C (void) GLIB_DEPRECATED_IN_2_30; void function_D (void) GLIB_AVAILABLE_IN_2_32; void function_E (void) GLIB_AVAILABLE_IN_2_34; any application code using the above functions will get the following compiler warnings: function_A: deprecated symbol warning function_B: deprecated symbol warning function_C: no warning function_D: no warning function_E: undefined symbol warning This means that it should be possible to gradually port code towards non-deprecated API gradually, on a per-release basis. https://bugzilla.gnome.org/show_bug.cgi?id=670542
