From 51bada696f77de9d7f673884cec9560218654fae Mon Sep 17 00:00:00 2001 From: Sergey Sharybin Date: Wed, 11 Jan 2012 08:51:06 +0000 Subject: Longer names support for all ID and other object names This commit extends limit of ID and objects to 64 (it means 63 meaning characters and 1 for zero-terminator). CustomData layers names are also extended. Changed DNA structures and all places where length constants were hardcoded. All names which are "generating" from ID block should be limited by MAX_ID_NAME-2, all non-id names now has got own define called MAX_NAME which should be used all over for non-id names to make further name migration stuff easier. All name fields in DNA now have comment with constant which corresponds to hardcoded numeric value which should make it easier to further update this limits or even switch to non-hardcoded values in DNA. Special thanks to Campbell who helped figuring out some issues and helped a lot in finding all cases where hardcoded valued were still used in code. Both of forwards and backwards compatibility is stored with blender versions newer than January 5, 2011. Older versions had issue with placing null-terminator to DNA strings on file load which will lead to some unpredictable behavior or even crashes. --- source/blender/makesdna/DNA_defs.h | 3 +++ 1 file changed, 3 insertions(+) (limited to 'source/blender/makesdna/DNA_defs.h') diff --git a/source/blender/makesdna/DNA_defs.h b/source/blender/makesdna/DNA_defs.h index 575938da653..46d7fc2b009 100644 --- a/source/blender/makesdna/DNA_defs.h +++ b/source/blender/makesdna/DNA_defs.h @@ -47,4 +47,7 @@ #define USE_BMESH_FORWARD_COMPAT +/* non-id name variables should use this length */ +#define MAX_NAME 64 + #endif /* DNA_DEFS_H */ -- cgit v1.2.3
