From fb4c7f27d050a167335a4274327cf1f8d8cc9aba Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Johannes=20Wei=C3=9Fl?= Date: Sun, 14 May 2017 23:35:37 +0200 Subject: Fix httpc timeout for redirects Probably since 6153ba7 (OTP R13B04) the httpc timeout setting does not work for redirects (when autoredirect is true). With this patch a new timer is started for the new (redirected) requests. This means that a simple redirected request could return after 2*timeout milliseconds. This is the first part to fix https://bugs.erlang.org/browse/ERL-420 --- lib/inets/src/http_client/httpc_handler.erl | 16 ++++++++++------ lib/inets/test/httpc_SUITE.erl | 19 +++++++++++++++++++ 2 files changed, 29 insertions(+), 6 deletions(-) (limited to 'lib/inets') diff --git a/lib/inets/src/http_client/httpc_handler.erl b/lib/inets/src/http_client/httpc_handler.erl index c99200777b..89c17a8679 100644 --- a/lib/inets/src/http_client/httpc_handler.erl +++ b/lib/inets/src/http_client/httpc_handler.erl @@ -1224,7 +1224,7 @@ close_socket(#session{socket = Socket, socket_type = SocketType}) -> http_transport:close(SocketType, Socket). activate_request_timeout( - #state{request = #request{timer = undefined} = Request} = State) -> + #state{request = #request{timer = OldRef} = Request} = State) -> Timeout = (Request#request.settings)#http_options.timeout, case Timeout of infinity -> @@ -1232,17 +1232,21 @@ activate_request_timeout( _ -> ReqId = Request#request.id, Msg = {timeout, ReqId}, + case OldRef of + undefined -> + ok; + _ -> + %% Timer is already running!
