Merge #12119: [wallet] use P2WPKH change output if any destination is P2WPKH or P2WSH
596c446 [wallet] use P2WPKH change output if any destination is P2WPKH or P2WSH (Sjors Provoost)

Pull request description:

  If `-changetype` is not explicitly set, then regardless of `-addresstype`, the wallet will use a ~`bech32` change address~ `P2WPKH` change output if any destination is `P2WPKH` or `P2WSH`.

  This seems more intuitive to me and more in line with the spirit of [BIP-69](https://github.com/bitcoin/bips/blob/master/bip-0069.mediawiki).

  When combined with #11991 a QT user could opt to use `bech32` exclusively without having to figure out how to launch with `-changetype=bech32`, although so would #11937.

Pull request description:

  Makes the `command` optional, since there are valid bitcoin-cli calls that have no `command`:

  * `bitcoin-cli -?`
  * `bitcoin-cli -getinfo`
  * ...

  Also, rename self.args to self.options, since that is the name in the `bitcoin-cli -help` documentation.

Merge #11415: [RPC] Disallow using addresses in createmultisig
1df206f Disallow using addresses in createmultisig (Andrew Chow)

Pull request description:

  This PR should be the last part of #7965.

  This PR makes createmultisig only accept public keys and marks the old functionality of accepting addresses as deprecated.

  It also splits `_createmultisig_redeemscript` into two functions, `_createmultisig_getpubkeys` and `_createmultisig_getaddr_pubkeys`. `_createmultisig_getpubkeys` retrieves public keys from the RPC parameters and `_createmultisig_getaddr_pubkeys` retrieves addresses' public keys from the wallet. `_createmultisig_getaddr_pubkeys` requires the wallet and is only used by `addwitnessaddress` (except when `createmultisig` is used in deprecated mode).

  `addwitnessaddress`'s API is also changed. Instead of returning just an address, it now returns the same thing as `createmultisig`: a JSON object with two fields, address and redeemscript.

Merge #12220: Error if relative -walletdir is specified
ec527c6 Don't allow relative -walletdir paths (Russell Yanofsky)

Pull request description:

  This makes it an error to explicitly specify a non-absolute -walletdir path, and also adds a debug.log warning if a relative rather than absolute -datadir path is configured.

  Specifying paths relative to the current working directory in a daemon process can be dangerous, because files can fail to be located even if the configuration doesn't change, but the daemon is started up differently.

  Specifying a relative -datadir now adds a warning to the debug log. It would not be backwards-compatible to forbid relative -datadir paths entirely, and it could also be inconvenient for command line testing.

  Specifying a relative -walletdir now results in a startup error. But since the -walletdir option is new in 0.16.0, there should be no compatibility issues. Another reason not to use working directory paths for -walletdir specifically is that the default -walletdir is a "wallets" subdirectory inside the datadir, so it could be surprising that setting -walletdir manually would choose a directory rooted in a completely different location.

Pull request description:

  Commit e545dedf72 moved `TransactionAddedToMempool` to the background scheduler thread. Thus, adding a transaction to the mempool will no longer add it to the wallet immediately. Functional tests, that `sync_mempools` and then call into wallet rpcs will race against the scheduler thread.

134cdc7 Test walletpassphrase timeout bounds and clamping (Andrew Chow)
0b63e3c Clamp walletpassphrase timeout to 2^(30) seconds and check its bounds (Andrew Chow)

Pull request description:

  Fixes #12100

  Makes the timeout be clamped to 2^30 seconds to avoid the issue with sign flipping with large timeout values and thus relocking the wallet instantly. Unlocking for at most ~34 years should be sufficient.

  Also checks that the timeout is not negative to avoid instant relocks.

Pull request description:

  Splitting #11774 into two parts -- this part updates the README with the proposed naming convention, and adds some checks to test_runner.py that the number of tests violating the naming convention doesn't increase too much. Idea is this part of the change should not introduce merge conflicts or require much rebasing, so reviews of the complicated bits won't become invalidated too often; while the second part will just be file renames, which will require regular rebasing and will introduce merge conflicts with pending PRs, but can be merged later, and should also be much easier to review, since it will only include relatively trivial changes.

1df206f854 Disallow using addresses in createmultisig
Make createmultisig only accept public keys with the old functionality
marked as deprecated.

Splits _createmultisig_redeemscript into two functions, one for
getting public keys from UniValue and one for getting addresses
from UniValue and then their respective public keys. The one for
retrieving address's public keys is located in rpcwallet.cpp

Changes addwitnessaddress's output to be a JSON object with
two fields, address and redeemscript.

Adds a test to deprecated_rpc.py for testing the deprecation.

Update the tests to use addwitnessaddress or give only public keys
to createmultisig. Anything that used addwitnessaddress was also
updated to reflect the new API.

Pull request description:

  This implements a minimum viable implementation of SegWit wallet support, based on top of #11389, and includes part of the functionality from #11089.

  Two new configuration options are added:
  * `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`.
  * `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used.

  All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version.

  The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key.

  To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used:
  * All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date.
  * All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software.
  * All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work.

  These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented.

  `dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

940a21932b SegWit wallet support
This introduces two command line flags (-addresstype and -changetype) which control
the type of addresses/outputs created by the GUI and RPCs. Certain RPCs allow
overriding these (`getnewaddress` and `getrawchangeaddress`). Supported types
are "legacy" (P2PKH and P2SH-multisig), "p2sh-segwit" (P2SH-P2WPKH and P2SH-P2WSH-multisig),
and "bech32" (P2WPKH and P2WSH-multisig).

A few utility functions are added to the wallet to construct different address type
and to add the necessary entries to the wallet file to be compatible with earlier
versions (see `CWallet::LearnRelatedScripts`, `GetDestinationForKey`,
`GetAllDestinationsForKey`, `CWallet::AddAndGetDestinationForScript`).

Pull request description:

  As discussed in https://github.com/bitcoin/bitcoin/pull/11289#issuecomment-334600457, adds the CScripts from the wallet to the `dumpwallet` RPC and then allows them to be imported with the `importwallet` RPC. Includes a basic test, and modifies the helptext of the dumpwallet RPC.

  Notes:
  - Reviewers: use `?w=1` to avoid the indentation-only change in commit `Add scripts to importwallet RPC `
  - currently the scripts are followed with `# addr=` comments just as the other keys are, unsure if this might confuse users into thinking all the scripts are for valid P2SH addresses though, but I don't think that should be an issue.
  - there are no birthtimes for scripts, so script imports don't affect rescans
  - `importwallet` imports the CScripts but I'm not sure how to approach specifying whether scripts are for P2SH addresses, BIP173 addresses, etc. whether that matters or not. Otherwise the RPC helptext might just need modification.

  Fixes #11715

Pull request description:

  Adds a new functional test for testing various command line and configuration file argument interactions, that aren't specific enough to other functionality to be placed in other tests.

  Currently this tests the error messages for non-existent datadir, which would have caught the bug fixed in https://github.com/bitcoin/bitcoin/pull/11829. It also tests that command line arguments override the ones in the config file.

  I plan on working on a fix for https://github.com/bitcoin/bitcoin/issues/11819 / https://github.com/bitcoin/bitcoin/issues/1044 and then expanding this test with cases for that.

2e02984591 [tests] node_network_limited - remove race condition
node_network_limited had a race condition, since wait_for_block()
doesn't do what you might expect. It only checks the most recent block
received over the P2P interface (perhaps we should rename the method
wait_for_most_recent_block() to avoid future confusion). The test can
fail if the node sends us invs for other blocks, we respond with a
getdata, and the node sends us one of those blocks in the 0.05 second
wait_until loop window.

Fix this by not responding to inv messages with getdata messages.

Pull request description:

  Suggested in https://github.com/bitcoin/bitcoin/pull/10481#issuecomment-325244946, this adds the option to explicitly choose whether a serialized transaction should be decoded as a witness or non-witness transaction rather than relying on the heuristic checks in #10481. The parameter defaults to relying on #10481 if not included, but it overrides that if included.

Pull request description:

  [Reviewer hint: use [?w=1](https://github.com/bitcoin/bitcoin/pull/10275/files?w=1) to avoid seeing a bunch of indentation changes.]

  Presuming a user knows the block hash of the block containing a given transaction, this PR allows them to fetch the raw transaction, even without `-txindex`. It also enables support for getting transactions that are in orphaned blocks.

  Note that supplying a block hash will override mempool and txindex support in `GetTransaction`. The rationale behind this is that a transaction may be in multiple places (orphaned blocks) and if the user supplies an explicit block hash it should be adhered to.

  ```Bash
  $ # a41.. is a tx inside an orphan block ..3c6f.. -- first try getting it normally
  $ ./bitcoin-cli getrawtransaction a41e66ee1341aa9fb9475b98cfdc1fe1261faa56c0a49254f33065ec90f7cd79 1

  No such mempool transaction. Use -txindex to enable blockchain transaction queries. Use gettransaction for wallet transactions.

Pull request description:

  This patch adds an option to configure the name and/or directory of the debug log file.

  The user can specify either a relative path, in which case the path is relative to the (network specific) data directory. They can also specify an absolute path to put the log anywhere else in the file system.

  Alternative to #11741 that gets rid of the concept of a "log directory" by specifying the path for the specific kind of log, the debug log. Which happens to be the only kind of log we have at this point*, but a hypothetical new kind of log (say, an audit log) would get a new option. This has more flexibility than specifying a directory which has to contain all of them.

  \* excluding `db.log` which is internally generated by the wallet database library, but that one moves along with `-walletdir`.

  > Currently, when a functional test fails, the debug logs are printed sequentially to the travis log. This makes debugging race conditions based on the travis log hard. Instead, all logs events should be combined and sorted by their timestamp, then appended to the travis log.

  This is the final step in #11518, except for possibly renaming - for motivation, please see that PR.

  If this is merged, then migrating the test framework from asyncore to asyncio should be easier (I say should because I haven't dug too deeply into what would be required).

  Requesting review from @ryanofsky , since he always has good feedback on these refactor PRs, and I'd appreciate his take on this refactor. Note particularly that I've reverted the change suggested here: https://github.com/bitcoin/bitcoin/pull/11182#discussion_r148859555 . The idea, as always, is to present a simple interface to the test writer.

Pull request description:

  Closes #11348

  Adds a `-walletdir` parameter which specifies a directory to use for wallets, allowing them to be stored separately from the 'main' data directory. Creates a new `wallets/` directory in datadir if this is the first time running, and defaults to using it if it exists.

  Includes tests and release notes. Things which might need to be considered more:
  - there is no 'lock' on the wallets directory, which might be needed?
  - because this uses a new wallets/ directory by default, downgrading to an earlier version won't see the wallets in that directory (not a big deal though, users can just copy them up to the main dir)
  - jnewbery suggested putting each wallet in its own directory, which is a good idea, but out of scope for this PR IMO. EDIT: this is being done in https://github.com/bitcoin/bitcoin/pull/11687
  - doc/files.md needs updating (will do soon)

  I also considered including  a cleanup by removing caching of data directory paths and instead just initialise them once on startup (c.f. #3073), but decided it wasn't super relevant here will just complicate review.

f0c4ab9a70 [tests] fix flakiness in sendheaders.py
Fixes to sources of intermittent failure in sendheaders.py

- at the start of test_null_locators(), a new block is generated and
then a getheaders is sent. check_last_accouncement() is called to assert
that the headers message is received. However, the new block triggers an
inv to be sent over both P2P connections, so there's a race. If the inv
is received at the wrong time, the test fails.

- test_null_locators() ends by sending a block to the node under test.
At the start of test_nonnull_locators(), a block is mined and
check_last_announcement() is called to assert that the inv received is
for the same block. That means there's a race: if the inv from the block
sent in test_null_locators() is received at the wrong time, the test
fails.

Pull request description:

  Exposing whether the node is in IBD would help for testing, and may be useful in general, particularly for developers.

  First discussed in #10357 here: https://github.com/bitcoin/bitcoin/pull/10357#pullrequestreview-59963870

  > ... we could simplify this (and possibly other) tests by just adding a way to know if a node is in IBD. I'd like to do that, but I'm not sure it makes sense to complicate this PR with discussion over how that information should be made available. Eg it's not clear to me that the notion of being in IBD is worth exposing to the casual user, versus a hidden rpc call or something, since the definition has changed over time, and may continue to change in the future. But I still do agree that at least for testing purposes it would be far simpler to expose the field somehow...

   This PR currently implements the simplest way of doing this: adding an `initialblockdownload` field to `getblockchaininfo`. Other approaches we could take:

  1. add a new debug RPC method that exposes `IBD` and potentially other information.
  2. add a parameter to `getblockchaininfo`, eg `debug_info`, which would cause it to return debug information including IBD
  3. add a query string to the url `?debug=true` which would cause RPCs to return additional debug information.

  I quite like the idea of (3). Feedback on these and other approaches very much welcomed!

725b79a [test] Verify node doesn't send headers that haven't been fully validated (Russell Yanofsky)
3788a84 Do not send (potentially) invalid headers in response to getheaders (Matt Corallo)

Pull request description:

  Nowhere else in the protocol do we send headers which are for
  blocks we have not fully validated except in response to getheaders
  messages with a null locator. On my public node I have not seen any
  such request (whether for an invalid block or not) in at least two
  years of debug.log output, indicating that this should have minimal
  impact.

Pull request description:

  This is the first part of #11518. It removes a ~150 lines of unused code from the mininode module:

  - remove unused `deliver_sleep_time` and `EarlyDisconnectError` code
  - remove support for pre-BIP31 ping messages
  - remove support for alert message
  - explicitly don't support p2p versions lower than 60001

  Should be an easy ACK for reviewers. If all extended tests pass, then this code really was dead :)

Pull request description:

  Most tests shouldn't have to deal with the now-historical SegWit activation transition (and other deployments, but SegWit is certainly the hardest one to accomodate).

  This PR makes a versionbits starttime of -1 equal to "always active", and enables it by default for SegWit on regtest. Individual tests can override this by using the existing `-vbparams` option.

  A few unit tests and functional tests are adapted to indeed override vbparams, as they specifically test the transition.

  This is in preparation for wallet SegWit support, but I thought having earlier eyes on it would be useful.

Pull request description:

  @sdaftuar pointed out that the version in #11487 was somewhat DoS-able as someone could feed you a valid chain that forked off the the last checkpoint block and force you to do lots of work just walking backwards across blocks for each new block they gave you. We came up with a few proposals but settled on the one implemented here as likely the simplest without obvious DoS issues. It uses our existing on-load mapBlockIndex walk to make sure everything that descends from an invalid block is marked as such, and then simply caches blocks which we attempted to connect but which were found to be invalid. To avoid DoS issues during IBD, this will need to depend on #11458.

  Includes tests from #11487.

Merge #11490: Disconnect from outbound peers with bad headers chains
e065249 Add unit test for outbound peer eviction (Suhas Daftuar)
5a6d00c Permit disconnection of outbound peers on bad/slow chains (Suhas Daftuar)
c60fd71 Disconnecting from bad outbound peers in IBD (Suhas Daftuar)

Pull request description:

  The first commit will disconnect an outbound peer that serves us a headers chain with insufficient work while we're in IBD.

  The second commit introduces a way to disconnect outbound peers whose chains fall out of sync with ours:

  For a given outbound peer, we check whether their best known block (which is known from the blocks they announce to us) has at least as much work as our tip.  If it doesn't, we set a 20 minute timeout, and if we still haven't heard about a block with as much work as our tip had when we set the timeout, then we send a single getheaders message, and wait 2 more minutes.  If after two minutes their best known block has insufficient work, we disconnect that peer.

  We protect 4 of our outbound peers (who provide some "good" headers chains, ie a chain with at least as much work as our tip at some point) from being subject to this logic, to prevent excessive network topology changes as a result of this algorithm, while still ensuring that we have a reasonable number of nodes not known to be on bogus chains.

  We also don't require our peers to be on the same chain as us, to prevent accidental partitioning of the network in the event of a chain split.  Note that if our peers are ever on a more work chain than our tip, then we will download and validate it, and then either reorg to it, or learn of a consensus incompatibility with that peer and disconnect.  This PR is designed to protect against peers that are on a less work chain which we may never try to download and validate.
