From e3687f790a77f616966ad9feea8db1693fda2303 Mon Sep 17 00:00:00 2001 From: Kittywhiskers Van Gogh <63189531+kwvg@users.noreply.github.com> Date: Wed, 26 Jun 2024 11:48:16 +0000 Subject: [PATCH] test, bench: remove globals vCoins and testWallet from test and bench adapted from a5595b13 and 5e54aa9b in bitcoin#23288. changes to coinselector_tests must be reverted before backports related to it are done as these changes are primarily motivated by bitcoin#21866 taking away the global chainstate, which breaks coinselector_tests and these changes skips over a lot of backporting, making them incompatible with backporting efforts (or even the commits its adapted from). the existing behaviour was that it creates its own testNode but doesn't populate it with a ChainstateManager (or much at all) while the rest of the client uses WalletTestingSetup's values. for the longest time this was fine because addCoins > listMNCollaterials > ChainActive() meant that it was using the fallback, but when chainstate globals are removed, WalletTestingSetup's values can't serve as a fallback anymore as it'd now be looking for NodeContext::chainman::m_chain, and chainman wasn't setup with testNode and the tests crash. --- src/bench/coin_selection.cpp | 10 +- src/wallet/test/coinselector_tests.cpp | 406 +++++++++++++------------ 2 files changed, 209 insertions(+), 207 deletions(-) diff --git a/src/bench/coin_selection.cpp b/src/bench/coin_selection.cpp index 3b82351928b2f..9f1a75a553425 100644 --- a/src/bench/coin_selection.cpp +++ b/src/bench/coin_selection.cpp @@ -61,10 +61,6 @@ static void CoinSelection(benchmark::Bench& bench) } typedef std::set CoinSet;
