From 17a74fcfc74936b48923bba5a416be73a01d2367 Mon Sep 17 00:00:00 2001 From: Wilmer Paulino Date: Thu, 27 Apr 2023 13:31:04 -0700 Subject: [PATCH] Use helper to create dummy blocks `rust-bitcoin v0.30.0` introduces concrete variants for data members of block `Header`s. To avoid having to update these across every use, we introduce new helpers to create dummy blocks and headers, such that the update process is a bit more straight-forward. --- fuzz/src/chanmon_consistency.rs | 7 +- fuzz/src/full_stack.rs | 9 +- lightning-background-processor/src/lib.rs | 6 +- lightning-persister/src/lib.rs | 7 +- lightning/src/chain/chainmonitor.rs | 12 +- lightning/src/chain/channelmonitor.rs | 8 +- lightning/src/ln/chanmon_update_fail_tests.rs | 12 +- lightning/src/ln/channelmanager.rs | 5 +- lightning/src/ln/functional_test_utils.rs | 35 +++--- lightning/src/ln/functional_tests.rs | 117 ++++++------------ lightning/src/ln/payment_tests.rs | 16 +-- lightning/src/ln/reorg_tests.rs | 21 +--- 12 files changed, 86 insertions(+), 169 deletions(-) diff --git a/fuzz/src/chanmon_consistency.rs b/fuzz/src/chanmon_consistency.rs index 837386bd9..7d507fa43 100644 --- a/fuzz/src/chanmon_consistency.rs +++ b/fuzz/src/chanmon_consistency.rs @@ -18,8 +18,6 @@ //! send-side handling is correct, other peers.
