2022-02-03refactor: replace boost::filesystem with std::filesystemKiminuo
Warning: Replacing fs::system_complete calls with fs::absolute calls in this commit may cause minor changes in behaviour because fs::absolute no longer strips trailing slashes; however these changes are believed to be safe.

2021-11-15refactor: Make CWalletTx sync state type-safeRussell Yanofsky
Current CWalletTx state representation makes it possible to set inconsistent states that won't be handled correctly by wallet sync code or serialized & deserialized back into the same form. For example, it is possible to call setConflicted without setting a conflicting block hash, or setConfirmed with no transaction index. And it's possible update individual m_confirm and fInMempool data fields without setting an overall consistent state that can be serialized and handled correctly. Fix this without changing behavior by using std::variant, instead of an enum and collection of fields, to represent sync state, so state tracking code is safer and more legible. This is a first step to fixing state tracking bugs https://github.com/bitcoin-core/bitcoin-devwiki/wiki/Wallet-Transaction-Conflict-Tracking, by adding an extra margin of safety that can prevent new bugs from being introduced as existing bugs are fixed.
2021-10-22walletdb: Use SQLiteDatabase for mock wallet databasesAndrew Chow
Default to SQLiteDatabase instead of BerkeleyDatabase for CreateDummyWalletDatabase. Most tests already use descriptor wallets and the mock db doesn't really matter for tests. The tests where it does matter will make the db directly.
2021-10-05refactor: Block unsafe fs::path std::string conversion callsRussell Yanofsky
There is no change in behavior. This just helps prepare for the transition from boost::filesystem to std::filesystem by avoiding calls to methods which will be unsafe after the transaction to std::filesystem to due lack of a boost::filesystem::path::imbue equivalent and inability to set a predictable locale.

2021-09-01refactor: Detach wallet transaction methods (followup for move-only)Russell Yanofsky
Followup to commit "MOVEONLY: CWallet transaction code out of wallet.cpp/.h" that detaches and renames some CWalletTx methods, making into them into standalone functions or CWallet methods instead. There are no changes in behavior and no code changes that aren't purely mechanical. It just gives spend and receive functions more consistent names and removes the circular dependencies added by the earlier MOVEONLY commit. There are also no comment or documentation changes. Removed comments from transaction.h are just migrated to spend.h, receive.h, and wallet.h.

Currently if you run same `importdescriptors` command twice with a descriptor containing private key you will get very confusing error — `Missing required fields`. What happens is that Wallet tries to write imported private key to the disk, but it exists already so we get `DB_KEYEXIST (-30995)` from BerkelyDB. Please note, that we set `DB_NOOVERWRITE` (I guess not to lose some keys accidentally). The exception is caught in `catch (...)` in rpcdump.cpp with a generic error. With this PR if a descriptor is already present than we will update its activeness, internalness, label, range and next_index. For the range only expansion is allowed (range start can only decrease, range end increase).

New function is not currently called but will be called in upcoming commits. It moves database path checking, and existence checking, and already-loaded checking, and verification into a single function so this logic does not need to be repeated all over higher level wallet code, and so higher level code does not need to change when SQLite support is added in https://github.com/bitcoin/bitcoin/pull/19077. This also lets higher level wallet code make fewer assumptions about the contents of wallet directories. This commit just adds the new function and does not change behavior in any way.

This should have only been initializing the cache when one does not exist. However this code itself is unnecessary as the act of looking up the cache to add to it will initialize it if it didn't already exist. This issue could be hit by trying to load a wallet that had imported a multisig descriptor. The wallet would fail to load. A test has been added to wallet_importdescriptors.py to catch this case.

This PR replaces those functions with `Add*` and `Load*` variants so that they follow the pattern used elsewhere in the wallet. `AddHDChain`, `AddActiveScriptPubKeyMan`, and `AddWalletFlags` both set their respective variables in `CWallet` and writes them to disk. These functions are used by the actions which modify the wallet such as `sethdseed`, `importdescriptors`, and creating a new wallet. `LoadHDChain`, `LoadActiveScriptPubKeyMan`, and `LoadWalletFlags` just set the `CWallet` variables. These functions are used by `LoadWallet` when loading the wallet from disk.

It doesn't make sense for these to be standalone nor for them to be static functions. So instead, move them from `BerkeleyBatch` into `BerkeleyDatabase` and make them member functions instead of static. `BerkeleyBatch::VerifyEnvironment` and `BerkeleyBatch::VerifyDatabaseFile` are combined into a single `BerkeleyDatabase::Verify` function that operates on that `BerkeleyDatabase` object. `BerkeleyBatch::Rewrite` and `BerkeleyBatch::PeriodicFlush` both took a `BerkeleyDatabase` as an argument and did stuff on it. So we just make it a member function so it doesn't need to take a database as an argument.

2020-07-03walletdb: don't reinitialize desc cache with multiple cache entriesAndrew Chow
When loading descriptor caches, we would accidentally reinitialize the descriptor cache when seeing that one already exists. This should have only been initializing the cache when one does not exist. However this code itself is unnecessary as the act of looking up the cache to add to it will initialize it if it didn't already exist. This issue could be hit by trying to load a wallet that had imported a multisig descriptor. The wallet would fail to load. A test has been added to wallet_importdescriptors.py to catch this case. Another test case has also been added to check that loading a wallet with only single key descriptors works.
