See service_bundle.dtd.1 for XML definitions 34 * of templates, and the svccfg code for information on how those definitions 35 * are translated into the repository. 36 * 37 * The main data structures are scf_pg_tmpl and scf_prop_tmpl. These 38 * are allocated by the callers through scf_tmpl_[pg|prop]_create(), and 39 * destroyed with scf_tmpl_[pg|prop]_destroy(). They are populated by 40 * scf_tmpl_get_by_pg_name(), scf_tmpl_get_by_pg(), and 41 * scf_tmpl_get_by_prop(). They also store the iterator state for 42 * scf_tmpl_iter_pgs() and scf_tmpl_iter_props(). 43 * 44 * These data structures are then consumed by other functions to 45 * gather information about the template (e.g. name, description, 46 * choices, constraints, etc.). 47 * 48 * scf_tmpl_validate_fmri() does instance validation against template 49 * data, and populates a set of template errors which can be explored using 50 * the scf_tmpl_next_error() and the scf_tmpl_error*() suite of functions. 51 * 52 * The main data structures for template errors are scf_tmpl_errors, 53 * defined in this file, and scf_tmpl_error, defined in libscf_priv.h. 54 * scf_tmpl_error is shared with svccfg to offer common printing 55 * of error messages between libscf and svccfg. 56 * 57 * General convenience functions are towards the top of this file, 58 * followed by pg and prop template discovery functions, followed 59 * by functions which gather information about the discovered 60 * template. Validation and error functions are at the end of this file. 61 */ 62 63 #include "lowlevel_impl.h" 64 #include "libscf_impl.h" 65 #include <assert.h> 66 #include <errno.h> 67 #include <libintl.h> 68 #include <stdlib.h> 69 #include <stdio.h> 70 #include <strings.h> 71 #include <locale.h> 72 #include <ctype.h> 73 #include <inttypes.h> 74 75 #define SCF_TMPL_PG_COMMON_NAME_C "common_name_C" 76 77 #define SCF__TMPL_ITER_NONE 0 78 #define SCF__TMPL_ITER_INST 1 79 #define SCF__TMPL_ITER_RESTARTER 2 80 #define SCF__TMPL_ITER_GLOBAL 3 81 82 #define SCF_TMPL_PG_NT 0 83 #define SCF_TMPL_PG_N 1 84 #define SCF_TMPL_PG_T 2 85 #define SCF_TMPL_PG_WILD 3 86 87 struct scf_pg_tmpl { 88 int pt_populated; 89 scf_handle_t *pt_h; 90 scf_propertygroup_t *pt_pg; 91 scf_service_t *pt_orig_svc; 92 scf_service_t *pt_svc; 93 scf_instance_t *pt_orig_inst; 94 scf_instance_t *pt_inst; 95 scf_snapshot_t *pt_snap; 96 int pt_is_iter; 97 scf_iter_t *pt_iter; 98 int pt_iter_last; 99 }; 100 101 #define SCF_WALK_ERROR -1 102 #define SCF_WALK_NEXT 0 103 #define SCF_WALK_DONE 1 104 105 struct pg_tmpl_walk { 106 const char *pw_snapname; 107 const char *pw_pgname; 108 const char *pw_pgtype; 109 scf_instance_t *pw_inst; 110 scf_service_t *pw_svc; 111 scf_snapshot_t *pw_snap; 112 scf_propertygroup_t *pw_pg; 113 const char *pw_target; 114 char *pw_tmpl_pgname; 115 }; 116 117 typedef struct pg_tmpl_walk pg_tmpl_walk_t; 118 119 typedef int walk_template_inst_func_t(scf_service_t *_svc, 120 scf_instance_t *_inst, pg_tmpl_walk_t *p); 121 122 struct scf_prop_tmpl { 123 int prt_populated; 124 scf_handle_t *prt_h; 125 scf_pg_tmpl_t *prt_t; 126 scf_propertygroup_t *prt_pg; 127 char *prt_pg_name; 128 scf_iter_t *prt_iter; 129 }; 130 131 /* 132 * Common server errors are usually passed back to the caller.
