From: Sebastian Harl Date: Wed, 29 Jan 2014 20:55:58 +0000 (+0100) Subject: store: Added support for different data-types for attributes. X-Git-Tag: sysdb-0.1.0~229 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=c9ed4d2a7a92ef589809a7df9b04c061afa4ef64;p=sysdb.git store: Added support for different data-types for attributes. An attribute value is now stored as sdb_data_t, supporting all data-types which are supported by that type. JSON-serialization does not fully support that yet, though. --- diff --git a/src/backend/puppet/store-configs.c b/src/backend/puppet/store-configs.c index a9a0ff7..e109b30 100644 --- a/src/backend/puppet/store-configs.c +++ b/src/backend/puppet/store-configs.c @@ -87,7 +87,7 @@ sdb_puppet_stcfg_get_attrs(sdb_dbi_client_t __attribute__((unused)) *client, const char *hostname; const char *key; - const char *value; + sdb_data_t value; sdb_time_t last_update; assert(n == 4); @@ -98,10 +98,11 @@ sdb_puppet_stcfg_get_attrs(sdb_dbi_client_t __attribute__((unused)) *client, hostname = data[0].data.string; key = data[1].data.string; - value = data[2].data.string; + value.type = SDB_TYPE_STRING; + value.data.string = data[2].data.string; last_update = data[3].data.datetime; - status = sdb_store_attribute(hostname, key, value, last_update); + status = sdb_store_attribute(hostname, key, &value, last_update); if (status < 0) { sdb_log(SDB_LOG_ERR, "puppet::store-configs backend: Failed to " diff --git a/src/core/store.c b/src/core/store.c index e8d14a0..2522233 100644 --- a/src/core/store.c +++ b/src/core/store.c @@ -71,7 +71,7 @@ struct sdb_store_base { typedef struct { sdb_store_base_t super; - char *value; + sdb_data_t value; } sdb_attribute_t; #define SDB_ATTR(obj) ((sdb_attribute_t *)(obj)) #define SDB_CONST_ATTR(obj) ((const sdb_attribute_t *)(obj)) @@ -158,20 +158,19 @@ sdb_store_obj_destroy(sdb_object_t *obj) static int sdb_attr_init(sdb_object_t *obj, va_list ap) { - const char *value; + const sdb_data_t *value; int ret; - /* this will consume the first argument (type) of ap */ + /* this will consume the first two arguments + * (type and last_update) of ap */ ret = store_base_init(obj, ap); if (ret) return ret; - value = va_arg(ap, const char *); + value = va_arg(ap, const sdb_data_t *); - if (value) { - SDB_ATTR(obj)->value = strdup(value); - if (!
