From 205c80427ba6f5751d1aef800f1dd00d736a3ca9 Mon Sep 17 00:00:00 2001 From: jeff Date: Thu, 21 Sep 2023 22:33:00 -0500 Subject: [PATCH] wallet: store watch-only wallet correctly when `change_password()` is called The Monero GUI code was calling `Monero::wallet::setPassword()` on every open/close for some reason, and the old `store_to()` code called `store_keys()` with `watch_only=false`, even for watch-only wallets. This caused a bug where the watch-only keys file got saved with with the JSON field `watch_only` set to 0, and after saving a watch-only wallet once, a user could never open it back up against because `load()` errored out. This never got brought up before this because you would have to change the file location of the watch-only wallet to see this bug, and I guess that didn't happen often, but calling the new `store_to()` function with the new `force_rewrite` parameter set to `true` triggers key restoring and the bug appeared. --- src/wallet/wallet2.cpp | 4 ++-- 1 file changed, 2 insertions(+), 2 deletions(-) diff --git a/src/wallet/wallet2.cpp b/src/wallet/wallet2.cpp index c5c66d4e5..a450cc9eb 100644 --- a/src/wallet/wallet2.cpp +++ b/src/wallet/wallet2.cpp @@ -4460,7 +4460,7 @@ boost::optional wallet2::get_keys_file_data(const epee: value2.SetInt(m_key_device_type); json.AddMember("key_on_device", value2, json.GetAllocator()); - value2.SetInt(watch_only ? 1 :0); // WTF ?
