21520b95515676d45145df624f430cdd39db7515 fuzz: add target for coinselection (Martin Zumsande) Pull request description: This adds a fuzz target for the coinselection algorithms by creating random `OutputGroup`s and running all three coin selection algorithms for them. It does not fuzz higher-level wallet logic for selecting eligible coins (as in `SelectCoins()`), thought it probably would make sense to have a fuzz target for that too.

So this PR adds fields that are present in `CInputCoin` to `COutput` and replaces the usage of `CInputCoin` with `COutput`. `COutput` is also moved to coinselection.h. As part of this move, the usage of `CWalletTx` is removed from `COutput`. It is instead replaced by storing a `COutPoint` and the `CTxOut` rather than the entire `CWalletTx` as coin selection does not really need the full `CWalletTx`. The `CWalletTx` was only used for figuring out whether the transaction containing the output was from the current wallet, and for the transaction's time. These are now parameters to `COutput`'s constructor.

`sqlite.h` 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. ACKs for top commit: achow101: ACK 39b1763730177cd7d6a32fd9321da640b0d65e0e ryanofsky: Code review ACK 39b1763730177cd7d6a32fd9321da640b0d65e0e.

2022-02-22blockstorage: Make m_block_index own CBlockIndex'sCarl Dong
Instead of having CBlockIndex's live on the heap, which requires manual memory management, have them be owned by m_block_index. This means that they will live and die with BlockManager. A change to BlockManager::LookupBlockIndex: - Previously, it was a const member function returning a non-const CBlockIndex* - Now, there's are const and non-const versions of BlockManager::LookupBlockIndex returning a CBlockIndex with the same const-ness as the member function: (e.g. const CBlockIndex* LookupBlockIndex(...) const) See next commit for some weirdness that this eliminates. The range based for-loops are modernize (using auto + destructuring) in a future commit.

2022-02-04Re-enable walletinit_verify_walletdir_no_trailing2 test disabled in #20744Ryan Ofsky
This should also fix an init error if a -walletdir with a trailing slash is used on windows. This appears to be a real error and regression introduced with #20744. On windows (or at least wine), fs calls that actuallly access the filesystem like fs::equivalent or fs::exists seem to treat directory paths with trailing slashes as not existing, so it's necessary to normalize these paths before using them. This change passes canonical paths to fs calls validating the -walletdir path to fix this.
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.

2021-12-06Remove unused (and broken) functionality in SpanReaderPieter Wuille
This removes the ability to set an offset in the SpanReader constructor, as the current code is broken. All call sites use pos=0, so it is actually unused. If future call sites need it, SpanReader{a, b, c, d} is equivalent to SpanReader{a, b, c.subspan(d)}. It also removes the ability to deserialize from SpanReader directly from the constructor. This too is unused, and can be more idiomatically simulated using (SpanReader{a, b, c} >> x >> y >> z) instead of SpanReader{a, b, c, x, y, z}.

When a receiving address is generated externally to the wallet (e.g. same wallet running on two nodes, or by 3rd party from xpub) 2. When restoring backup with lost metadata, but keypool gap is not exceeded yet When the block is connected or tx added to mempool we already mark used keys. This PR extends this logic to determine whether the destination is a receiving one and if yes add it to the address book with empty label. Works both for legacy and descriptors wallets. - For legacy it uses the internal flag from the keypool entry. Caveat: because we don't know which script type would be used we add all possible destinations for such keys. - For descriptor wallets it uses internal flag for the script pub key manager. Caveat: it only works for active descriptors. fixes #19856 fixes #20293 ACKs for top commit: laanwj: Code review ACK 3d71d16d1eb4173c70d4c294559fc2365e189856 Tree-SHA512: 03fafd5548ead0c4ffe9ebcc9eb2849f1d2fa7270fda4166419b86877d4e57dcf04460e465fbb9c90b42031f3c05d1b83f1b67a9f82c2a42980825ed1e7b52e6

2021-11-27Merge bitcoin/bitcoin#22868: wallet: Call load handlers without cs_wallet lockedSamuel Dobson
f13a22a631efe01e1fbae4ae78a4901d14ebda3c wallet: Call load handlers without cs_wallet locked (João Barbosa) Pull request description: Don't have `cs_wallet` locked while calling each `context.wallet_load_fns`. A load handler can always lock `cs_wallet` if needed. The lock was added in 1c7e25db0c to satisfy TSAN. With 44c430ffac most of the code requiring the lock is in `CWallet::AttachChain`. A comment is added to warn about wallets_mutex and cs_wallet lock ordering.
