From e97653ccf3356c57100606f0a0a175dbf4676df7 Mon Sep 17 00:00:00 2001 From: Bastien Montagne Date: Thu, 16 Sep 2021 14:26:49 +0200 Subject: Fix: properly implement the 'only append' execption case for WorkSpaces. Add needed extra flag and utils to IDType to mark and check an ID type as only appendable. Note that this is only a loose user-level enforcement currently, in any case you need to be able to link an ID to append it currently, so for low-level code this does not really matter. Currently only WorkSpace and Screen ID types are marked with the new `IDTYPE_FLAGS_ONLY_APPEND` flag. --- source/blender/blenkernel/BKE_idtype.h | 5 +++++ source/blender/blenkernel/intern/idtype.c | 24 +++++++++++++++++++--- source/blender/blenkernel/intern/screen.c | 2 +- source/blender/blenkernel/intern/workspace.c | 2 +- .../blender/windowmanager/intern/wm_files_link.c | 5 ++--- 5 files changed, 30 insertions(+), 8 deletions(-) diff --git a/source/blender/blenkernel/BKE_idtype.h b/source/blender/blenkernel/BKE_idtype.h index 3b45db19919..7136a3fd7af 100644 --- a/source/blender/blenkernel/BKE_idtype.h +++ b/source/blender/blenkernel/BKE_idtype.h @@ -45,6 +45,10 @@ enum { IDTYPE_FLAGS_NO_COPY = 1 << 0, /** Indicates that the given IDType does not support linking/appending from a library file. */ IDTYPE_FLAGS_NO_LIBLINKING = 1 << 1, + /** Indicates that the given IDType should not be directly linked from a library file, but may be + * appended. + * NOTE: Mutually exclusive with `IDTYPE_FLAGS_NO_LIBLINKING`. */ + IDTYPE_FLAGS_ONLY_APPEND = 1 << 2, /** Indicates that the given IDType does not have animation data. */ IDTYPE_FLAGS_NO_ANIMDATA = 1 << 3, }; @@ -285,6 +289,7 @@ const char *BKE_idtype_idcode_to_translation_context(const short idcode); bool BKE_idtype_idcode_is_valid(const short idcode); bool BKE_idtype_idcode_is_linkable(const short idcode); +bool BKE_idtype_idcode_is_only_appendable(const short idcode); /* Macro currently, since any linkable IDtype should be localizable. */ #define BKE_idtype_idcode_is_localizable BKE_idtype_idcode_is_linkable diff --git a/source/blender/blenkernel/intern/idtype.c b/source/blender/blenkernel/intern/idtype.c index fee70922570..b2efccc53c4 100644 --- a/source/blender/blenkernel/intern/idtype.c +++ b/source/blender/blenkernel/intern/idtype.c @@ -224,10 +224,10 @@ bool BKE_idtype_idcode_is_valid(const short idcode) } /** - * Return non-zero when an ID type is linkable. + * Check if an ID type is linkable. * - * \param idcode: The code to check. - * \return Boolean, 0 when non linkable. + * \param idcode: The IDType code to check. + * \return Boolean, false when non linkable, true otherwise. */ bool BKE_idtype_idcode_is_linkable(const short idcode) { @@ -236,6 +236,24 @@ bool BKE_idtype_idcode_is_linkable(const short idcode) return id_type != NULL ?
