2022-09-19Merge bitcoin/bitcoin#26005: Wallet: Fix error handling (copy_file failure ↵fanquake
in RestoreWallet, and in general via interfaces) c3e536555aa3a7db773170671da1256a2ace2094 Bugfix: Wallet: Return util::Error rather than non-error nullptr when CreateWallet/LoadWallet/RestoreWallet fail (Luke Dashjr) 335ff98c8a64eda38a2a2334102bd253f108c253 Bugfix: Wallet: Wrap RestoreWallet content in a try block to ensure exceptions become returned errors and incomplete wallet directory is removed (Luke Dashjr) Pull request description: Bug 1: `copy_file` can throw exceptions, but `RestoreWallet` is expected to return a nullptr with a populated `errors` parameter. This is fixed by wrapping `copy_file` and `LoadWallet` (for good measure) in a `try` block, and converting any exceptions to the intended return style. Bug 2: `util::Result` turns what would have been a `false` unique_ptr into a `true` nullptr result, which leads to nullptr dereferences in at least the 3 cases of wallet creation/loading/restoring. This is fixed by keeping the pointer as a plain `std::unique_ptr` until actually returning it (ie, after the nullptr check).

This ends up being random as `mapWallet` is a `std::unordered_map`. However `ReacceptWalletTransactions` (used for adding to the mempool on loading) first sorts the txs by wallet insertion order, then submits them. The result is that `ResendWalletTranactions` will fail to rebroadcast child transactions if their txids happen to be lexicographically less than their parent's txid. This PR resolves this issue by combining `ReacceptWalletTransactions` and `ResendWalletTransactions` into a new `ResubmitWalletTransactions` so that the iteration code and basic checks are shared. A test has also been added that checks that such transaction chains are rebroadcast correctly.

Migrated wallets will need a new backup. If a wallet has watchonly stuff in it, a new watchonly descriptor wallet will be created containing those watchonly things. The related transactions, labels, and descriptors for those watchonly things will be removed from the original wallet. Migrated wallets will not have any of the legacy things be available for fetching from `getnewaddress` or `getrawchangeaddress`. Wallets that have private keys enabled will have newly generated descriptors. Wallets with private keys disabled will not have any active `ScriptPubKeyMan`s. For the basic HD wallet case of just generated keys, in addition to the standard descriptor wallet descriptors using the master key derived from the pre-existing hd seed, the migration will also create 3 descriptors for each HD chain in: a ranged combo external, a ranged combo internal, and a single key combo for the seed (the seed is a valid key that we can receive coins at!). The migrated wallet will then have newly generated descriptors as the active `ScriptPubKeyMan`s. This is equivalent to creating a new descriptor wallet and importing the 3 descriptors for each HD chain. For wallets containing non-HD keys, each key will have its own combo descriptor. There are also tests.

2022-08-29wallet: Deduplicate Resend and ReacceptWalletTransactionsAndrew Chow
Both of these functions do almost the exact same thing. They can be deduplicated so that their behavior matches except for the filtering aspect. As this function will now always be called on wallet loading, nNextResend will also always be initialized, so wallet_resendwallettransactions.py is updated to account for that. This also resolves a bug where ResendWalletTransactions would fail to rebroadcast txs in insertion order thereby potentially rebroadcasting a child transaction before its parent and causing the child to not actually get rebroadcast. Also names the combined function to ResubmitWalletTransactions as the function just submits the transactions to the mempool rather than doing any sending by itself.

When Bitcoin Core creates a wallet, it's `minversion` is set to `FEATURE_BASE`, which is 10500. However, once the wallet is unloaded using `unloadwallet` or through program termination, and subsequently loaded again, `loadwallet` updates the `minversion` in the wallet.dat file to `FEATURE_LATEST`, currently 169900. The current logging format prints the very old wallet version during `createwallet`, and then the actual version in calls to `loadwallet`. This has confused at least one person ([reference](https://bitcointalk.org/index.php?topic=5410650.0) - I was the one who asked there if there were plans to change that behavior, and was subsequently redirected here by achow), so it will be very helpful to users to explicitly specify in the logs what the walletdb is doing.

Waste calculation is now consistent with tx building code. Before we always assumed change for knapsack even when the solution is changeless4. 2. simpler tx building code. Only create change output when it's needed 3. makes it easier to correctly account for fees for CPFP inputs (should be done in a follow up) In the first three commits we fix the code to accurately track selection target in `SelectionResult::m_target` Then we introduce new variable `min_change` that represents the minimum viable change amount Then we introduce `SelectionResult::GetChange()` which incapsulates dropping change for fee logic and uses correct values of `SelectionResult::m_target` Then we use `SelectionResult::GetChange()` in both tx building and waste calculation code This PR is a refactoring and shouldn't change the behaviour. There is only one known small change (arguably a bug fix). Before we dropped change output if it's smaller than `cost_of_change` after paying change fees. This is incorrect as `cost_of_change` already includes `change_fee`.

1dc03dda05e9dce128e57f05bb7b1bb02b3cfb9e [doc] remove non-signaling mentions of BIP125 (glozow) 32024d40f03fbf47c64d814fa5f2c2a73ec14cb7 scripted-diff: remove mention of BIP125 from non-signaling var names (glozow) Pull request description: We have pretty thorough documentation of our RBF policy in doc/policy/mempool-replacements.md. It enumerates each rule with several sentences of rationale. Also, each rule pretty much has its own function (3 and 4 share one), with extensive comments. The doc states explicitly that our rules are similar but differ from BIP125, and contains a record of historical changes to RBF policy. We should not use "BIP125" as synonymous with our RBF policy because: - Our RBF policy is different from what is specified in BIP125, for example: - the BIP does not mention our rule about the replacement feerate being higher (our Rule 6) - the BIP uses minimum relay feerate for Rule 4, while we have used incremental relay feerate since #9380 - the "inherited signaling" question (CVE-2021-31876). Call it discrepancy, ambiguous wording, doc misinterpretation, or implementation details, I would recommend users refer to doc/policy/mempool-replacements.md - the signaling policy is configurable, see #25353 - Our RBF policy may change further - We have already marked BIP125 as only "partially implemented" in docs/bips.md since 1fd49eb498c75a1d14193bb736d195a3dc75ae12 - See comments from people who are not me recently: - https://github.com/bitcoin/bitcoin/pull/25038#discussion_r909507429 - https://github.com/bitcoin/bitcoin/pull/25575#issuecomment-1179519204 This PR removes all non-signaling mentions of BIP125 (if people feel strongly, we can remove all mentions of BIP125 period). It may be useful to refer to the concept of "tx opts in to RBF if it has at least one nSequence less than (0xffffffff - 1)" as "BIP125 signaling" because: - It is succint. - It has already been widely marketed as BIP125 opt-in signaling. - Our API uses it when referring to signaling (e.g. getmempoolentry["bip125-replaceable"] and wallet error message "not BIP 125 replaceable"). Changing those is more invasive. - If/when we have other ways to signal in the future, we can disambiguate them this way. See #25038 which proposes another way of signaling, and where I pulled these commits from. Alternatives: - Changing our policy to match BIP125. This doesn't make sense as, for example, we would have to remove the requirement that a replacement tx has a higher feerate (Rule 6). - Changing BIP125 to match what we have. This doesn't make sense as it would be a significant change to a BIP years after it was finalized and already used as a spec to implement RBF in other places. - Document our policy as a new BIP and give it a number. This might make sense if we don't expect things to change a lot, and can be done as a next step.

This does not work for bumping in the GUI nor `bumpfee` because these need private keys available to sign and send the transaction. But `psbtbumpfee` returns a psbt, so it is fine to not be able to sign. In order to correctly estimate the size of the inputs for coin selection, the fee bumper will use the size of the inputs of the transaction being bumped. Because the sizes of signatures are not guaranteed, for external inputs, the fee bumper will verify the scripts with a special SignatureChecker which will compute the weight of all of the signatures in that input, and compute their weights if those signatures were maximally sized. This allows the fee bumper to obtain a max size estimate for each external input. Builds on #23201 as it relies on the ability to pass weights in to coin selection.

In some cases, notably psbtbumpfee, it is okay, and potentially desired, to be able to bump the fee of a transaction which contains external inputs.

2022-08-19bumpfee: extract weights of external inputs when bumping feeAndrew Chow
When bumping the fee of a transaction containing external inputs, determine the weights of those inputs. Because signatures can have a variable size, the script is executed with a special SignatureChecker which will compute the total weight of the signatures in the transaction and the weight if they were all maximum size signatures. This allows us to compute the maximum weight of the input for use during coin selection.
