If the descriptor entry is unrecognized/corrupt, the unserialization fails and
`LoadWallet` instead of stop there and return the error, continues reading all
the db records. As other records tied to the unrecognized/corrupted descriptor
are scanned, a fatal error is thrown.

|
|
This avoids initializing variables with the copy-constructor of a
non-trivially copyable type.

c318211ddd48d44dd81dded553afeee3bc41c89e walletdb: fix last client version update (furszy)
bda8ebe608e6572eaaf40cd28dab6954241c9b0d wallet: don't read db every time that a new WalletBatch is created (furszy)
Pull request description:
Found it while was working on #25297.
We are performing a db read operation every time that a new `WalletBatch` is created, inside the constructor, just to check if the client version field is inside the db or not.
As the client version field does not change in the entire db lifecycle, this operation can be done only once: The first time that the db is accessed/opened and the client version value can be cached.

39b1763730177cd7d6a32fd9321da640b0d65e0e Replace use of `ArgsManager` with `DatabaseOptions` (Kiminuo)
Pull request description:
Contributes to #21005.
The goal of this PR is to remove `gArgs` from database classes (i.e. `bdb.h` and `sqlite.h`) so that they can be tested without relying on `gArgs` in tests.
Notes:
* My goal is to enable unit-testing without relying on `gArgs` as much as possible. Global variables are hard to reason about which in turn makes it slightly harder to contribute to this codebase. When the compiler does the heavy lifting for us and allows us only to construct an object (or call a method) with valid parameters, we may also save some time in code reviews. The cost for this is passing an argument which is not for free but the cost is very miniscule compared to benefits, I think.
* GUI code is an exception because it seems fine to have `gArgs` there so I don't plan to make changes in `src/qt` folder, for example.
* My approach to removal of `gArgs` uses is moving from lower levels to upper ones and pass `ArgsManager` as an argument as needed. The approach is very similar to what #20158.

0652ee73ec880a66ec88bde007ee03c0b9d1b074 Add size check on meta.key_origin.path (Rob Fielding)
Pull request description:
Currently inactive HD chains are only derived from at the time a key in that chain is found to have been used. However, at that time, the wallet may not be able to derive keys (e.g. it is locked). Currently we would just move on and not derive any new keys, however this could result in missing funds.
This PR resolves this problem by adding memory only variables to `CHDChain` which track the highest known index. `TopUp` is modified to always try to top up the inactive HD chains, and this process will use the new variables to determine how much to top up. In this way, after an encrypted wallet is unlocked, the inactive HD chains will be topped up and hopefully funds will not be missed.
Note that because these variables are not persisted to disk (because `CHDChain`s for inactive HD chains are not written to disk), if an encrypted wallet is not unlocked in the same session as a key from an inactive chain is found to be used, then it will not be topped up later unless more keys are found.
Additionally, wallets which do not have upgraded key metadata will not derive any keys from inactive HD chains. This is resolved by using the derivation path string in `CKeyMetadata.hdKeypath` to determine what indexes to derive.

When build CHDChains out of CKeyMetadata, the chain counters are
actually 1 based, not 0 based, so 1 must be added to each index.
|
|
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.
|
|
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.
|
|
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.

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.

bf68ebc1cd555f791103f81adc9111e0e55c8003 wallet: allow to import same descriptor twice (S3RK)
Pull request description:
Rationale: allow updating existing descriptors with `importdescriptors` command.
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).

32def8d1c29e0855fe5429687acabd2f29119316 Catch ios_base::failure specifically (Peter Bushnell)
Pull request description:
In https://github.com/bitcoin/bitcoin/pull/2950 a hash of the pubkey and private was added to speed up key import, this was made backwards compatible by reading the hash in a try block with an ellipses catch all in case the hash was not present.
CDataStream::read() specifically throws std::ios_base::failure, backwards compatibility expects only that error to be thrown, if something else gets thrown we should not be catching it. The change in this commit is to catch that exception only. If any other exception is thrown other than std::ios_base::failure it will be caught by the wider try block and an error written to the log and/or console.
CDataStream::read() throwing std::ios_base::failure.
