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/sasl/src/release_handler_1.erl | 15 ++++++++++----- lib/stdlib/doc/src/gen_server.xml | 10 +++++++--- lib/stdlib/src/gen_server.erl | 2 +- lib/stdlib/src/supervisor.erl | 2 +- 4 files changed, 19 insertions(+), 10 deletions(-) (limited to 'lib') diff --git a/lib/sasl/src/release_handler_1.erl b/lib/sasl/src/release_handler_1.erl index 37275eff45..93d12cf609 100644 --- a/lib/sasl/src/release_handler_1.erl +++ b/lib/sasl/src/release_handler_1.erl @@ -505,15 +505,20 @@ resume(Pids) -> change_code(Pids, Mod, Vsn, Extra, Timeout) -> Fun = fun(Pid) -> - case Timeout of - default -> - ok = sys:change_code(Pid, Mod, Vsn, Extra); - _Else -> - ok = sys:change_code(Pid, Mod, Vsn, Extra, Timeout) + case sys_change_code(Pid, Mod, Vsn, Extra, Timeout) of + ok -> + ok; + {error,Reason} -> + throw({code_change_failed,Pid,Mod,Vsn,Reason}) end end, lists:foreach(Fun, Pids). +sys_change_code(Pid, Mod, Vsn, Extra, default) -> + sys:change_code(Pid, Mod, Vsn, Extra); +sys_change_code(Pid, Mod, Vsn, Extra, Timeout) -> + sys:change_code(Pid, Mod, Vsn, Extra, Timeout). + stop(Mod, Procs) -> lists:zf(fun({undefined, _Name, _Pid, _Mods}) -> false; diff --git a/lib/stdlib/doc/src/gen_server.xml b/lib/stdlib/doc/src/gen_server.xml index 1045766e01..edeb7dff91 100644 --- a/lib/stdlib/doc/src/gen_server.xml +++ b/lib/stdlib/doc/src/gen_server.xml @@ -4,7 +4,7 @@

State is the internal state of the gen_server.

Extra is passed as-is from the {advanced,Extra} part of the update instruction.

The function should return the updated internal state.

If successful, the function shall return the updated + internal state.

If the function returns {error,Reason}, the ongoing + upgrade will fail and roll back to the old release.
