From 7687f7873b75c3cbdfa15ab570211dc39d24ab80 Mon Sep 17 00:00:00 2001 From: Andrew Chow Date: Wed, 6 Feb 2019 21:26:55 -0500 Subject: [PATCH] [wallet] Support creating a blank wallet A blank wallet is a wallet that has no keys, script or watch only things. A new wallet flag indicating that it is blank will be set when the wallet is blank. Once it is no longer blank (a seed has been generated, keys or scripts imported, etc), the flag will be unset. --- doc/release-notes-15226.md | 8 ++ src/interfaces/wallet.cpp | 1 + src/interfaces/wallet.h | 3 + src/qt/walletmodel.cpp | 7 +- src/rpc/client.cpp | 1 + src/wallet/crypter.cpp | 2 +- src/wallet/rpcwallet.cpp | 30 ++++-- src/wallet/test/wallet_tests.cpp | 1 + src/wallet/wallet.cpp | 66 ++++++++++-- src/wallet/wallet.h | 23 ++++- test/functional/test_runner.py | 4 +- test/functional/wallet_createwallet.py | 100 +++++++++++++++++++ test/functional/wallet_disableprivatekeys.py | 46 --------- 13 files changed, 221 insertions(+), 71 deletions(-) create mode 100644 doc/release-notes-15226.md create mode 100755 test/functional/wallet_createwallet.py delete mode 100755 test/functional/wallet_disableprivatekeys.py diff --git a/doc/release-notes-15226.md b/doc/release-notes-15226.md new file mode 100644 index 00000000000..3be84db3e9b --- /dev/null +++ b/doc/release-notes-15226.md @@ -0,0 +1,8 @@ +Miscellaneous RPC changes +------------ + +- The RPC `createwallet` now has an optional `blank` argument that can be used to create a blank wallet. +Blank wallets do not have any keys or HD seed. +They cannot be opened in software older than 0.18. +Once a blank wallet has a HD seed set (by using `sethdseed`) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 0.17.x. +Encrypting a blank wallet will also set a HD seed for it. diff --git a/src/interfaces/wallet.cpp b/src/interfaces/wallet.cpp index 62ede0a95a3..339c5f24872 100644 --- a/src/interfaces/wallet.cpp +++ b/src/interfaces/wallet.cpp @@ -463,6 +463,7 @@ public: } unsigned int getConfirmTarget() override { return m_wallet.m_confirm_target;
