From ad7a9fb8e883f2b92cb0dcc19143490805eef425 Mon Sep 17 00:00:00 2001 From: "Kevin P. Fleming" Date: Mon, 26 Oct 2009 22:03:29 +0000 Subject: [PATCH] Correct broken logic from revision 225405. The code committed in revision 225405 was broken; instead of removing the unreference code, the logic used to decide when to do it should have been reversed. This patch corrects the situation, and makes reference counting work properly again. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@225955 65c4cc65-6c06-0410-ace0-fbb531ad65f3 --- main/astobj2.c | 11 ++++++++++- 1 file changed, 10 insertions(+), 1 deletion(-) diff --git a/main/astobj2.c b/main/astobj2.c index da52ab1f0d..a7dd7cc25f 100644 --- a/main/astobj2.c +++ b/main/astobj2.c @@ -685,6 +685,7 @@ static void *internal_ao2_callback(struct ao2_container *c, match &= cb_default(EXTERNAL_OBJ(cur->astobj), arg, flags); } + /* we found the object, performing operations according flags */ if (match == 0) { /* no match, no stop, continue */ continue; } else if (match == CMP_STOP) { /* no match but stop, we are done */ @@ -692,7 +693,6 @@ static void *internal_ao2_callback(struct ao2_container *c, break; } - /* we found the object, performing operations according flags */ /* we have a match (CMP_MATCH) here */ if (!(flags & OBJ_NODATA)) { /* if must return the object, record the value */ /* it is important to handle this case before the unlink */ @@ -719,6 +719,15 @@ static void *internal_ao2_callback(struct ao2_container *c, AST_LIST_REMOVE_CURRENT(entry); /* update number of elements */ ast_atomic_fetchadd_int(&c->elements, -1); + /* if the object is not going to be returned, we must decrement the reference count + * to account for the reference the container was holding + */ + if (flags & OBJ_NODATA) { + if (tag) + __ao2_ref_debug(EXTERNAL_OBJ(cur->astobj), -1, tag, file, line, funcname); + else + __ao2_ref(EXTERNAL_OBJ(cur->astobj), -1); + } ast_free(cur); /* free the link record */ }
