commit 308dde0c386158971a66c6e035b3f1ad67019eb5 Author: Taylor Yu <catalyst@torproject.org> Date: Thu Dec 13 17:18:49 2018 -0600 Remove unused old_state var in connection_or.c connection_or_change_state() saved an old_state to pass to channel_tls_handle_state_change_on_orconn(), which promptly cast it to void. Remove this unused variable and parameter. --- src/core/or/channeltls.c | 3 --- src/core/or/channeltls.h | 1 - src/core/or/connection_or.c | 6 +----- 3 files changed, 1 insertion(+), 9 deletions(-) diff --git a/src/core/or/channeltls.c b/src/core/or/channeltls.c index 8f407d5e1..cf33feec0 100644 --- a/src/core/or/channeltls.c +++ b/src/core/or/channeltls.c @@ -950,7 +950,6 @@ channel_tls_listener_describe_transport_method(channel_listener_t *chan_l) void channel_tls_handle_state_change_on_orconn(channel_tls_t *chan, or_connection_t *conn, - uint8_t old_state, uint8_t state) { channel_t *base_chan; @@ -959,8 +958,6 @@ channel_tls_handle_state_change_on_orconn(channel_tls_t *chan, tor_assert(conn); tor_assert(conn->chan == chan); tor_assert(chan->conn == conn); - /* Shut the compiler up without triggering -Wtautological-compare */ - (void)old_state; base_chan = TLS_CHAN_TO_BASE(chan); diff --git a/src/core/or/channeltls.h b/src/core/or/channeltls.h index 12715450b..2ec7fe545 100644 --- a/src/core/or/channeltls.h +++ b/src/core/or/channeltls.h @@ -49,7 +49,6 @@ channel_tls_t * channel_tls_from_base(channel_t *chan); void channel_tls_handle_cell(cell_t *cell, or_connection_t *conn); void channel_tls_handle_state_change_on_orconn(channel_tls_t *chan, or_connection_t *conn, - uint8_t old_state, uint8_t state); void channel_tls_handle_var_cell(var_cell_t *var_cell, or_connection_t *conn); diff --git a/src/core/or/connection_or.c b/src/core/or/connection_or.c index 962ec51c3..04ab4fe4a 100644 --- a/src/core/or/connection_or.c +++ b/src/core/or/connection_or.c @@ -408,16 +408,12 @@ connection_or_report_broken_states(int severity, int domain) static void connection_or_change_state(or_connection_t *conn, uint8_t state) { - uint8_t old_state; - tor_assert(conn); - old_state = conn->base_.state; conn->base_.state = state; if (conn->chan) - channel_tls_handle_state_change_on_orconn(conn->chan, conn, - old_state, state); + channel_tls_handle_state_change_on_orconn(conn->chan, conn, state); } /** Return the number of circuits using an or_connection_t; this used to
