From 038b9dd3a1f9bdd86cbb83bf3484ab1529d4fca2 Mon Sep 17 00:00:00 2001 From: Siri Hansen Date: Tue, 29 Nov 2011 15:37:11 +0100 Subject: Fix dialyzer warnings in supervisor Dialyzer complained over a mismatch between the callback spec of Mod:code_change in gen_server and the spec of supervisor:code_change (which is the implementation of a gen_server Mod:code_change). This commit changes the callback spec to allow {error,Reason} as return value. Also, release_handler is updated to handle this return value. --- lib/stdlib/src/supervisor.erl | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'lib/stdlib/src/supervisor.erl') diff --git a/lib/stdlib/src/supervisor.erl b/lib/stdlib/src/supervisor.erl index 2dd5ccce7a..42ea42f42e 100644 --- a/lib/stdlib/src/supervisor.erl +++ b/lib/stdlib/src/supervisor.erl @@ -37,7 +37,7 @@ %%-------------------------------------------------------------------------- --type child() :: pid() | 'undefined'. +-type child() :: 'undefined' | pid() | [pid()]. -type child_id() :: term(). -type mfargs() :: {M :: module(), F :: atom(), A :: [term()] | undefined}. -type modules() :: [module()] | 'dynamic'. -- cgit v1.2.3
