Now allow addresses to be communicated in a 'connected' message in the case of a connecting transport, so that diameter_tcp (in particular) can make local address configuration optional, communicating the gen_tcp default after connection establishment instead. --- lib/diameter/doc/src/diameter_transport.xml | 30 ++++++++++++++++++----------- lib/diameter/src/base/diameter_peer.erl | 8 ++++++-- lib/diameter/src/base/diameter_peer_fsm.erl | 13 +++++++++++-- 3 files changed, 36 insertions(+), 15 deletions(-) diff --git a/lib/diameter/doc/src/diameter_transport.xml b/lib/diameter/doc/src/diameter_transport.xml index 55b531155f..8bccf6521e 100644 --- a/lib/diameter/doc/src/diameter_transport.xml +++ b/lib/diameter/doc/src/diameter_transport.xml @@ -1,6 +1,8 @@ message()'> + MESSAGES'> + start/3'> inet:ip_address()'> @@ -12,7 +14,7 @@
