From: Matt Corallo Date: Mon, 15 Mar 2021 23:49:51 +0000 (-0400) Subject: Enforce block connection ordering in unit and functional tests X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=349d780103f72ad5dac7cb308acfed80eb1daf7d;p=rust-lightning Enforce block connection ordering in unit and functional tests This expands the assertions on block ordering to apply to `#[cfg(test)]` builds in addition to normal builds, requiring that unit and functional tests have syntactically-valid (ie the previous block hash pointer and the heights match the blocks) blockchains. This requires a reasonably nontrivial diff in the functional tests however it is mostly straightforward changes. --- diff --git a/lightning/src/ln/channelmanager.rs b/lightning/src/ln/channelmanager.rs index 997570ea3..50f8ccbb7 100644 --- a/lightning/src/ln/channelmanager.rs +++ b/lightning/src/ln/channelmanager.rs @@ -3302,16 +3302,10 @@ impl ChannelMana let _persistence_guard = PersistenceNotifierGuard::new(&self.total_consistency_lock, &self.persistence_notifier);
