From: Sebastian Harl Date: Tue, 22 Oct 2013 16:53:34 +0000 (+0200) Subject: Made log prefixes slightly more generic. X-Git-Tag: sysdb-0.1.0~336^2~40 X-Git-Url: https://git.tokkee.org/?a=commitdiff_plain;h=08f22afc30f1658a89aed05d4d596debe034c20a;p=sysdb.git Made log prefixes slightly more generic. Changed "plugin" to "core" and "sock" to "frontend". Those names better identify the context in which the error happened. --- diff --git a/src/core/plugin.c b/src/core/plugin.c index 472396f..09d5cce 100644 --- a/src/core/plugin.c +++ b/src/core/plugin.c @@ -218,7 +218,7 @@ plugin_unregister_by_name(const char *plugin_name) if (! obj) break; - sdb_log(SDB_LOG_INFO, "plugin: Unregistering " + sdb_log(SDB_LOG_INFO, "core: Unregistering " "%s callback '%s' (module %s)", type, obj->name, cb->cb_ctx->info.plugin_name); sdb_object_deref(obj); @@ -305,7 +305,7 @@ plugin_cb_init(sdb_object_t *obj, va_list ap) assert(obj); if (sdb_llist_search_by_name(*list, obj->name)) { - sdb_log(SDB_LOG_WARNING, "plugin: %s callback '%s' " + sdb_log(SDB_LOG_WARNING, "core: %s callback '%s' " "has already been registered.
