Pull request description:
This mode ('createwallet {"disableprivatekeys": true}') is intended for a sane pure watch-only mode, ideal for a use-case where one likes to use Bitcoin-Core in conjunction with a hardware-wallet or another solutions for cold-storage.
Since we have support for custom change addresses in `fundrawtransaction`, pure watch-only wallets including coin-selection are possible and do make sense for some use cases.
This new mode disables all forms of private key generation and ensure that no mix between hot and cold keys are possible.

using an uninitialized variable in path calculation.
27ee53c1ae wallet: Add error handling. Check return value of ParseUInt32(...) in ParseHDKeypath(...). (practicalswift)
7223263899 wallet: Add tests for ParseHDKeypath(...) (practicalswift)
Pull request description:
Add error handling. Check return value of `ParseUInt32(...)` in `ParseHDKeypath(...)`.
`ParseUInt32(...)` returns `false` if the entire string could not be parsed or when an overflow or underflow occurred. In such case the uninitialized variable `number` would be used in the calculation of `path` (prior to this commit).
An example key path triggering this is `m/0/4294967296`:
```
ParseHDKeypath("m/0/4294967296", keypath);
```
`4294967296` is `1` + `0xFFFFFFFF` (`uint32_t` max: `4294967295`).
Introduced in a4b06fb42eb0ad94e562ca839391b57e69285136 which was merged into `master` 14 hours ago as part of #13557 ("BIP 174 PSBT Serializations and RPCs").

41c607f09badb2c3ed58ff6fb17a8ebbef2cdabd Implement PSBT Structures and un/serialization methods per BIP 174 (Andrew Chow)
Pull request description:
This Pull Request fully implements the [updated](https://github.com/bitcoin/bips/pull/694) BIP 174 specification. It is based upon #13425 which implements the majority of the signing logic.
BIP 174 specifies a binary transaction format which contains the information necessary for a signer to produce signatures for the transaction and holds the signatures for an input while the input does not have a complete set of signatures.
This PR contains structs for PSBT, serialization, and deserialzation code. Some changes to `SignatureData` have been made to support detection of UTXO type and storing public keys.
***
Many RPCs have been added to handle PSBTs.
`walletprocesspsbt` takes a PSBT format transaction, updates the PSBT with any inputs related to this wallet, signs, and finalizes the transaction. There is also an option to not sign and just update.
`walletcreatefundedpsbt` creates a PSBT from user provided data in the same form as createrawtransaction. It also funds the transaction and takes an options argument in the same form as `fundrawtransaction`. The resulting PSBT is blank with no input or output data filled in. It is analogous to a combination of `createrawtransaction` and `fundrawtransaction`
`decodepsbt` takes a PSBT and decodes it to JSON. It is analogous to `decoderawtransaction`
`combinepsbt` takes multiple PSBTs for the same tx and combines them. It is analogous to `combinerawtransaction`
`finalizepsbt` takes a PSBT and finalizes the inputs. If all inputs are final, it extracts the network serialized transaction and returns that instead of a PSBT unless instructed otherwise.
`createpsbt` is like `createrawtransaction` but for PSBTs instead of raw transactions.
`convertpsbt` takes a network serialized transaction and converts it into a psbt. The resulting psbt will lose all signature data and an explicit flag must be set to allow transactions with signature data to be converted.
***
This supersedes #12136

Pull request description:
A check was added to the bitcoinconsensus verify_script codepath to ensure that callers only used _exposed_ interpreter flags. I think this error should be written to `bitcoinconsensus_err* err` and not returned by verify_script?
I modified the check so it indicates the error using *err like the others, and added tests covering the error codes.

Pull request description:
Alternative to #9152.
This takes `<n>` pubkeys and optionally `<n>` xpubs (together with a definable lookup windows where the default is 0-1000) and looks up common scripts in the UTXO set of all given or derived keys.
The output will be an array similar to `listunspent`. That array is compatible with `createrawtransaction` as well as with `signrawtransaction`.
This makes it possible to prepare sweeps and have them signed in a secure (cold) space.

to hide tx time
d45b344ffd Bucket for inbound when scheduling invs to hide tx time (Gleb)
Pull request description:
It has been brought up to my attention that current random delays mechanism (originally intended to obfuscate transaction metadata) allows to easily estimate the time a transaction was received by a node.
It may be done by connecting multiple observer nodes to the same node. Each of those nodes will generate its own schedule of delays. Combined metadata regarding those events from different sources allows an observer to estimate transaction time.
After this patch a spy won't gain additional information by just creating multiple connections to a target.

d58055d25f Move AddAndGetDestinationForScript from wallet to outputype module (Anthony Towns)

Pull request description:
Adds an "address_type" parameter that accepts "legacy", "p2sh-segwit", and "bech32" to choose the type of address created. Defaults to "legacy" rather than the value of the `-address-type` option for backwards compatibility.
As part of implementing this, OutputType is moved from wallet into its own module, and `AddAndGetDestinationForScript` is changed to apply to a `CKeyStore` rather than a wallet, and to invoke `keystore.AddCScript(script)` itself rather than expecting the caller to have done that.

Pull request description:
As part of a larger effort to decouple net_processing and validation a bit, these are a bunch of simple scope cleanups. I've moved things out of the header file that are only referenced in net_processing and added static (or anonymous namespace) modifiers to everything possible in net_processing.
There are a handful of functions which could be static except that they are exposed for the sake of unit testing - these are explicitly commented. There has been some discussion of a compile time annotation, but no conclusion has been reached on that yet.
This is somewhat related to other prs #12934 #13413 #13407 and will be followed by prs that reduce reliance on cs_main to synchronize data structures which are translation unit local to net_processing

7110c830f8 [wallet] deduplicate GetAvailableCredit logic (John Newbery)
ef7bc8893c [wallet] Factor out GetWatchOnlyBalance() (John Newbery)
4279da4785 [wallet] GetBalance can take an isminefilter filter. (John Newbery)
Pull request description:
#12953 inadvertently removed the functionality to call `getbalance "*" <int> <bool>` to get the wallet's balance with either minconfs or include_watchonly.
This restores that functionality (when `-deprecatedrpc=accounts`), and also makes it possible to call ``getbalance minconf=<int> include_watchonly=<bool>` when accounts are not being used.

The SignPSBTInput function takes a PSBTInput, SignatureData, SigningProvider,
and other data necessary for signing. It fills the SignatureData with data from
the PSBTInput, retrieves the UTXO from the PSBTInput, signs and finalizes the
input if possible, and then extracts the results from the SignatureData and
puts them back into the PSBTInput.
|
|
In preparation for more create transaction and fund transcation RPCs,
refactor the transaction creation and funding logic into separate
functions.
|
|
Added methods which move data to/from SignaturData objects to
PSBTInput and PSBTOutput objects.
Added sanity checks for PSBTs as a whole which are done immediately
after deserialization.
Added Merge methods to merge a PSBT into another one.
