It is fast, because it is basically * a binary dump. There are some details to mind when reconstructing * the file (endianness and byte-alignment). * * This little program scans all structs that need to be serialized, * and determined the names and types of all members. It calculates * how much memory (on disk or in ram) is needed to store that struct, * and the offsets for reaching a particular one. * * There is a facility to get verbose output from sdna. Search for * \ref debugSDNA. This int can be set to 0 (no output) to some int. Higher * numbers give more output. */ #include #include #include #include "MEM_guardedalloc.h" #include "../blenlib/BLI_sys_types.h" // for intptr_t support #define SDNA_MAX_FILENAME_LENGTH 255 /* Included the path relative from /source/blender/ here, so we can move */ /* headers around with more freedom. */ static const char *includefiles[] = { /* if you add files here, please add them at the end * of makesdna.c (this file) as well */ "DNA_listBase.h", "DNA_vec_types.h", "DNA_ID.h", "DNA_ipo_types.h", "DNA_key_types.h", "DNA_text_types.h", "DNA_packedFile_types.h", "DNA_gpu_types.h", "DNA_camera_types.h", "DNA_image_types.h", "DNA_texture_types.h", "DNA_lamp_types.h", "DNA_material_types.h", "DNA_vfont_types.h", "DNA_meta_types.h", "DNA_curve_types.h", "DNA_mesh_types.h", "DNA_meshdata_types.h", "DNA_modifier_types.h", "DNA_lattice_types.h", "DNA_object_types.h", "DNA_object_force_types.h", "DNA_object_fluidsim_types.h", "DNA_world_types.h", "DNA_scene_types.h", "DNA_view3d_types.h", "DNA_view2d_types.h", "DNA_space_types.h", "DNA_userdef_types.h", "DNA_screen_types.h", "DNA_sdna_types.h", "DNA_fileglobal_types.h", "DNA_sequence_types.h", "DNA_effect_types.h", "DNA_outliner_types.h", "DNA_sound_types.h", "DNA_group_types.h", "DNA_armature_types.h", "DNA_action_types.h", "DNA_constraint_types.h", "DNA_nla_types.h", "DNA_node_types.h", "DNA_color_types.h", "DNA_brush_types.h", "DNA_customdata_types.h", "DNA_particle_types.h", "DNA_cloth_types.h", "DNA_gpencil_types.h", "DNA_gpencil_modifier_types.h", "DNA_shader_fx_types.h", "DNA_windowmanager_types.h", "DNA_anim_types.h", "DNA_boid_types.h", "DNA_smoke_types.h", "DNA_speaker_types.h", "DNA_movieclip_types.h", "DNA_tracking_types.h", "DNA_dynamicpaint_types.h", "DNA_mask_types.h", "DNA_rigidbody_types.h", "DNA_freestyle_types.h", "DNA_linestyle_types.h", "DNA_cachefile_types.h", "DNA_layer_types.h", "DNA_workspace_types.h", "DNA_lightprobe_types.h", "DNA_hair_types.h", "DNA_groom_types.h", /* see comment above before editing! */ /* empty string to indicate end of includefiles */ "" }; static int maxdata = 500000, maxnr = 50000; static int nr_names = 0; static int nr_types = 0; static int nr_structs = 0; static char **names, *namedata; /* at address names[a] is string a */ static char **types, *typedata; /* at address types[a] is string a */ static short *typelens_native; /* at typelens[a] is the length of type 'a' on this systems bitness (32 or 64) */ static short *typelens_32; /* contains sizes as they are calculated on 32 bit systems */ static short *typelens_64; /* contains sizes as they are calculated on 64 bit systems */ static short **structs, *structdata; /* at sp = structs[a] is the first address of a struct definition * sp[0] is type number * sp[1] is amount of elements * sp[2] sp[3] is typenr, namenr (etc) */ /** * Variable to control debug output of makesdna. * debugSDNA: * - 0 = no output, except errors * - 1 = detail actions * - 2 = full trace, tell which names and types were found * - 4 = full trace, plus all gritty details */ static int debugSDNA = 0; static int additional_slen_offset; /* ************************************************************************** */ /* Functions */ /* ************************************************************************** */ /** * Add type \c str to struct indexed by \c len, if it was not yet found. * \param str char * \param len int */ static int add_type(const char *str, int len); /** * Add variable \c str to * \param str */ static int add_name(const char *str); /** * Search whether this structure type was already found, and if not, * add it. */ static short *add_struct(int namecode); /** * Remove comments from this buffer.
