From 1bee1e6269b76b52b1eab9112d39c245beaa27a2 Mon Sep 17 00:00:00 2001 From: Andrew Chow Date: Mon, 22 Jun 2020 17:58:18 -0400 Subject: [PATCH 1/2] Do not create default wallet No longer create a default wallet. The default wallet will still be loaded if it exists and not other wallets were specified (anywhere, including settings.json, bitcoin.conf, and command line). Tests are updated to be started with -wallet= if they need the default wallet. Added test to wallet_startup.py testing that no default wallet is created and that it is loaded if it exists and no other wallets were specified. --- doc/release-notes-15454.md | 6 +++++ src/interfaces/wallet.cpp | 11 ++++---- src/interfaces/wallet.h | 2 +- src/wallet/init.cpp | 11 +------- src/wallet/load.cpp | 25 ++++++++++++++++--- src/wallet/load.h | 4 +-- src/wallet/test/init_test_fixture.cpp | 2 +- src/wallet/test/wallet_test_fixture.h | 2 +- .../feature_backwards_compatibility.py | 4 +-- test/functional/feature_fee_estimation.py | 6 ++--- test/functional/feature_filelock.py | 4 +-- test/functional/mempool_compatibility.py | 2 +- test/functional/wallet_backup.py | 8 +++--- test/functional/wallet_dump.py | 2 +- test/functional/wallet_import_rescan.py | 4 +-- test/functional/wallet_multiwallet.py | 5 ++-- test/functional/wallet_startup.py | 10 ++++++++ test/functional/wallet_upgradewallet.py | 2 +- 18 files changed, 67 insertions(+), 43 deletions(-) create mode 100644 doc/release-notes-15454.md diff --git a/doc/release-notes-15454.md b/doc/release-notes-15454.md new file mode 100644 index 000000000..00c847a8d --- /dev/null +++ b/doc/release-notes-15454.md @@ -0,0 +1,6 @@ +Wallet +------ + +Bitcoin Core will no longer create an unnamed `""` wallet by default when no wallet is specified on the command line or in the configuration files. +For backwards compatibility, if an unnamed `""` wallet already exists and would have been loaded previously, then it will still be loaded. +Users without an unnamed `""` wallet and without any other wallets to be loaded on startup will be prompted to either choose a wallet to load, or to create a new wallet. diff --git a/src/interfaces/wallet.cpp b/src/interfaces/wallet.cpp index d19d0406b..94c63da84 100644 --- a/src/interfaces/wallet.cpp +++ b/src/interfaces/wallet.cpp @@ -488,8 +488,7 @@ public: class WalletClientImpl : public WalletClient { public: - WalletClientImpl(Chain& chain, ArgsManager& args, std::vector wallet_filenames) - : m_wallet_filenames(std::move(wallet_filenames)) + WalletClientImpl(Chain& chain, ArgsManager& args) { m_context.chain = &chain; m_context.args = &args; @@ -506,8 +505,8 @@ public: m_rpc_handlers.emplace_back(m_context.chain->handleRpc(m_rpc_commands.back())); } } - bool verify() override { return VerifyWallets(*m_context.chain, m_wallet_filenames); } - bool load() override { return LoadWallets(*m_context.chain, m_wallet_filenames); } + bool verify() override { return VerifyWallets(*m_context.chain); } + bool load() override { return LoadWallets(*m_context.chain); } void start(CScheduler& scheduler) override { return StartWallets(scheduler, *Assert(m_context.args)); } void flush() override { return FlushWallets(); } void stop() override { return StopWallets(); } @@ -566,9 +565,9 @@ public: std::unique_ptr MakeWallet(const std::shared_ptr& wallet) { return wallet ?
