From: Matt Corallo Date: Fri, 10 Feb 2023 19:29:13 +0000 (+0000) Subject: Replace `get_route` macro with a function X-Git-Tag: v0.0.115~76^2~7 X-Git-Url: http://git.bitcoin.ninja/index.cgi?a=commitdiff_plain;h=b5912eccf0f498a31383be9496ccaa12b12855f7;p=rust-lightning Replace `get_route` macro with a function The `get_route!()` macro has no reason to be a macro so here we move its logic to a function and leave the macro in place to avoid touching every line of code in the tests. This reduces the `--profile=test --lib` `Zpretty=expanded` code size from 326,588 LoC to 324,763 LoC. --- diff --git a/lightning/src/ln/functional_test_utils.rs b/lightning/src/ln/functional_test_utils.rs index 88e1b77f8..542dc6594 100644 --- a/lightning/src/ln/functional_test_utils.rs +++ b/lightning/src/ln/functional_test_utils.rs @@ -16,14 +16,14 @@ use crate::chain::transaction::OutPoint; use crate::ln::{PaymentPreimage, PaymentHash, PaymentSecret}; use crate::ln::channelmanager::{ChainParameters, ChannelManager, ChannelManagerReadArgs, RAACommitmentOrder, PaymentSendFailure, PaymentId, MIN_CLTV_EXPIRY_DELTA}; use crate::routing::gossip::{P2PGossipSync, NetworkGraph, NetworkUpdate}; -use crate::routing::router::{PaymentParameters, Route, get_route}; +use crate::routing::router::{self, PaymentParameters, Route}; use crate::ln::features::InitFeatures; use crate::ln::msgs; use crate::ln::msgs::{ChannelMessageHandler,RoutingMessageHandler}; use crate::util::enforcing_trait_impls::EnforcingSigner; use crate::util::scid_utils; use crate::util::test_utils; -use crate::util::test_utils::{panicking, TestChainMonitor}; +use crate::util::test_utils::{panicking, TestChainMonitor, TestScorer, TestKeysInterface}; use crate::util::events::{Event, HTLCDestination, MessageSendEvent, MessageSendEventsProvider, PathFailure, PaymentPurpose}; use crate::util::errors::APIError; use crate::util::config::UserConfig; @@ -1583,19 +1583,26 @@ macro_rules!
