From: Duncan Dean Date: Wed, 26 Apr 2023 12:57:18 +0000 (+0200) Subject: Use `env::temp_dir()` for BP tests X-Git-Tag: v0.0.116-alpha1~65^2 X-Git-Url: http://git.bitcoin.ninja/?a=commitdiff_plain;h=4abf3ba206a72612f46d9f0901be714b9007da6d;p=rust-lightning Use `env::temp_dir()` for BP tests Currently `BackgroundProcessor` tests create persister directories in the current working directory and rely on cleaning up in a `Drop` implementation. Unfortunately, it seems that in the async tests that nodes are not `drop()`ed for some reason and so the directories created by those tests remain behind in the current working directory. This commit at least ensures that these test directories are created in a temporary location for the OS using `temp_dir()`. It doesn't aim to solve the lack of cleanup in the async tests. Partial fix for #2224 but I believe it's enough to resolve it as these temp directories that do remain will be purged by the OS at some stage and are overwritten by subsequent tests if there is a conflict. --- diff --git a/lightning-background-processor/src/lib.rs b/lightning-background-processor/src/lib.rs index 3227b63fd..bc42c6eb6 100644 --- a/lightning-background-processor/src/lib.rs +++ b/lightning-background-processor/src/lib.rs @@ -859,7 +859,7 @@ mod tests { use lightning::util::persist::KVStorePersister; use lightning_persister::FilesystemPersister; use std::collections::VecDeque; - use std::fs; + use std::{fs, env}; use std::path::PathBuf; use std::sync::{Arc, Mutex}; use std::sync::mpsc::SyncSender; @@ -1116,7 +1116,9 @@ mod tests { path.to_str().unwrap().to_string() } - fn create_nodes(num_nodes: usize, persist_dir: String) -> Vec { + fn create_nodes(num_nodes: usize, persist_dir: &str) -> (String, Vec) { + let persist_temp_path = env::temp_dir().join(persist_dir); + let persist_dir = persist_temp_path.to_string_lossy().to_string(); let network = Network::Testnet; let mut nodes = Vec::new(); for i in 0..num_nodes { @@ -1129,7 +1131,7 @@ mod tests { let seed = [i as u8; 32]; let router = Arc::new(DefaultRouter::new(network_graph.clone(), logger.clone(), seed, scorer.clone())); let chain_source = Arc::new(test_utils::TestChainSource::new(Network::Testnet)); - let persister = Arc::new(FilesystemPersister::new(format!("{}_persister_{}", persist_dir, i))); + let persister = Arc::new(FilesystemPersister::new(format!("{}_persister_{}", &persist_dir, i))); let now = Duration::from_secs(genesis_block.header.time as u64); let keys_manager = Arc::new(KeysManager::new(&seed, now.as_secs(), now.subsec_nanos())); let chain_monitor = Arc::new(chainmonitor::ChainMonitor::new(Some(chain_source.clone()), tx_broadcaster.clone(), logger.clone(), fee_estimator.clone(), persister.clone())); @@ -1151,7 +1153,7 @@ mod tests { } } - nodes + (persist_dir, nodes) } macro_rules! open_channel { @@ -1223,7 +1225,7 @@ mod tests { // Test that when a new channel is created, the ChannelManager needs to be re-persisted with // updates.
