Also warn if bitcoind is configured to use a relative -datadir path.
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 also 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.

fa1e69e qa: Sync with validationinterface queue in sync_mempools (MarcoFalke)
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.
Fix that race by flushing the scheduler queue.

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.

Transaction selection for mining tracks ancestor feerates that are
modified based on transactions that have already been selected. This
commit de-duplicates the code so that the ancestor feerate sorting used
by the mempool can also be directly applied to the miner.
Clamps the timeout of walletpassphrase to 2^(30) seconds, which is
~34 years. Any number greater than that will be forced to be
2^(30). This avoids the sign flipping problem with large values which
can result in a negative time used.
Also perform bounds checks to ensure that the timeout is positive
to avoid immediate relocking of the wallet.
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.

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`).

3e1ee31 [Tests] Adding unit tests for GetDifficulty in blockchain.cpp. (sean)
Pull request description:
blockchain.cpp has low unit test coverage. This commit is intended
to start improving its code coverage to reasonable levels. One or more
follow up commits will complete the task that this commit is starting
(though the usefulness of this commit is not dependent upon later
commits).
Note that these tests were not written based upon a specification of how
GetDifficulty *should* work, but rather how it actually *does* work. As
a result, if there are any bugs in the current GetDifficulty
implementation, these unit tests serve to lock them in rather than
expose them.
-- Why has blockchain.cpp been modified if this is a unit testing change?
Since the existing GetDifficulty function relies on a global variable,
chainActive, it was not suitable for unit testing purposes. Both the
existing GetDifficulty function and the unit tests now call through to
a new, more modular version of GetDifficulty that can work on any chain,
not just chainActive.
-- Why does blockchain_tests.cpp directly include blockchain.cpp instead
of blockchain.h?
While the new GetDifficulty function's signature is arguably better than
the old one's, it still isn't great, and doesn't seem to warrant inclusion
as part of the blockchain.h API, especially since only test code is
directly using it. If a better way of exposing the new GetDifficulty
function to unit tests exists, please mention it and the commit will be
updated accordingly.
-- Why is the test fixture named blockchain_difficulty_tests rather than
blockchain_tests?
The Bitcoin Core policy for naming unit test files is to match the the
file under test ("blockchain" becomes "blockchain_tests"). While this
commit complies with that, blockchain.cpp is a massive file, such that
having all of the unit tests in one file will tend towards disorder.
Since there will be a lot more tests added to this file, the intention
is to divide up different types of tests into different test fixtures
within the same file.

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.

f455a24 [net] add seed.testnet.bitcoin.sprovoost.nl to testnet DNS seeds (Sjors Provoost)
Pull request description:
I tested it myself by:
* `dig seed.testnet.bitcoin.sprovoost.nl` (should have propagated by now, but if you only see two records with `A 66.111... ` try again later)
* deleting the other seeds and all data in `.../testnet3`, recompiling and then starting the node. Log shows `21 addresses found from DNS seeds`.
ACK https://github.com/bitcoin/bitcoin/blob/master/doc/dnsseed-policy.md
I'm willing to keep it up and running at least throughout 2018, unless something bad happens.
About my setup:
* Amazon EC2 instance in Europe, running Ubuntu 16.04; I use this instance for some other chores, but only port 53 is world reachable (for mainnet I'd probably run a dedicated instance, and perhaps a location I have physical control over)
* running [sipa/bitcoin-seeder](https://github.com/sipa/bitcoin-seeder) with default settings (and the non-root port redirect)
* feedback about my domain / DNS setup is welcome, I can provide more details via private email
I can use guidance on _Any hosting services contracted by the operator are equally expected to uphold these expectations_. Although I assume the requirements for testnet are less strict than for mainnet, in case I want to pursue the latter in the future: what unpleasant things can Amazon, my domain registrar and other intermediaries do? How would I mitigate that?
Also note that The Netherlands passed some pretty onerous legislation creating uncertainty over what the secret service can compel people like myself to do. However these laws won't take effect before mid 2018, there's probably more interesting targets than myself to go after, and it's easier for them to just monitor all unencrypted P2P traffic everywhere, or monitor some intermediary I depend on.
Any good tools for monitoring uptime?

2862b56 [tests] remove redundant univalue_tests.cpp (John Newbery)
Pull request description:
univalue unit tests were added in #4730 , and exist at `/src/test/univalue_tests.cpp` (outside the univalue tree). That test was brought into the univalue repository in https://github.com/bitcoin-core/univalue/pull/4 , which was pulled into the github repository in https://github.com/bitcoin/bitcoin/pull/11420.
That means that the univalue test exists in two places:
1. `/src/test/univalue_tests.cpp`
2. `/src/univalue/test/object.cpp`
(2) is a strict superset of (1). It adds some macros to work around boost not being a univalue dependency, and adds a few extra lines of test.
Therefore remove `/src/test/univalue_tests.cpp`

ecf9b25 remove unused fNoncriticalErrors variable from CWalletDB::FindWalletTx (Pierre Rochard)
Pull request description:
The `CWalletDB::FindWalletTx` method was patterned after `CWalletDB::LoadWallet`, where `fNoncriticalErrors` is used when a tx check fails in `ReadKeyValue`.
Since `FindWalletTx` is only used by methods which are zapping txs, it makes sense that `ReadKeyValue` is not called and the tx is not checked, so I think that deleting the unused `fNoncriticalErrors` boolean variable and its conditional statement is appropriate.

12781db [Tests] check specific validation error in miner tests (Sjors Provoost)
Pull request description:
## Problem
`BOOST_CHECK_THROW` merely checks that some `std::runtime_error` is
thrown, but not which one.
Here's an example of how this can cause a test to pass when a developer
introduces a consensus bug. The test for the sigops limit assumes
that `CreateNewBlock` fails with `bad-blk-sigops`. However it can
also fail with bad-txns-vout-negative, if a naive developer lowers
`BLOCKSUBSIDY` to `1*COIN`.
## Solution
`BOOST_CHECK_EXCEPTION` allows an additional predicate function. This
commit uses this for all exceptions that are checked for in
`miner_tets.cpp`:
* `bad-blk-sigops`
* `bad-cb-multiple`
* `bad-txns-inputs-missingorspent`
* `block-validation-failed`
If the function throws a different error, the test will fail. Although the message produced by Boost is a bit [confusing](http://boost.2283326.n4.nabble.com/Test-BOOST-CHECK-EXCEPTION-error-message-still-vague-tt4683257.html#a4683554), it does show which error was actually thrown. Here's what the above `1*COIN` bug would result in:
<img width="1134" alt="schermafbeelding 2017-09-02 om 23 42 29" src="https://user-images.githubusercontent.com/10217/29998976-815cabce-9038-11e7-9c46-f5f6cfb0ca7d.png">
## Other considerations
A more elegant solution in my opinion would be to subclass `std::runtime_error` for each `INVALID_TRANSACTION` type, but this would involve touching consensus code.
I put the predicates in `test_bitcoin.h` because I assume they can be reused in other test files. However [serialize_tests.cpp](https://github.com/bitcoin/bitcoin/blob/v0.15.0rc3/src/test/serialize_tests.cpp#L245) also uses `BOOST_CHECK_EXCEPTION` and it defines the predicate in the test file itself.
Instead of four `IsRejectInvalidReasonX(std::runtime_error const& e)` functions, I'd prefer something reusable like `bool IsRejectInvalidReason(String reason)(std::runtime_error const& e)`, which would be used like `BOOST_CHECK_EXCEPTION(functionThatThrows(), std::runtime_error, IsRejectInvalidReason("bad-blk-sigops")`. I couldn't figure out how to do that in C++.

Pull request description:
These changes are required to allow the Bitcoin source to build with Microsoft's C++ compiler (#11562 is also required).
I looked around for a better place for the typedef of ssize_t which is in random.h. The best candidate looks like src/compat.h but I figured including that header in random.h is a bigger change than the typedef. Note that the same typedef is in at least two other places including the OpenSSL and Berkeley DB headers so some of the Bitcoin code already picks it up.

Pull request description:
CChainState should eventually, essentially, be our exposed "libconsensus", but we're probably a few releases away, so the real goal is to clarify our internal interfaces. The main split was a big step, but validation.cpp is still a somewhat ranomly-mixed bag of functions that are pure functions which validate inputs (which should probably either merge with their callers or move into another file in consensus/), read/write data from disk, manipulate our current chain state (which moves into CChainState), and do mempool transaction validation.
Obviously this is only a small step, but some effort is made to clean up what functions the functions in CChainState call, and obviously as things are added its easy to keep clear "CChainState::* cannot call anything except via callbacks through CValidationInterface, pure functions, or disk read/write things". Right now there are some glaring violations in mempool callbacks, and general flushing logic needs cleaning up (FlushStateToDisk maybe shouldnt be called, and there should be an API towards setDirtyBlockIndex, but I'll leave that for after @sipa's current changesets land).

2dd6f80 Add a test that all flags are softforks (Pieter Wuille)
2851b77 Make all script verification flags softforks (Pieter Wuille)
Pull request description:
This change makes `SCRIPT_VERIFY_UPGRADABLE_NOPS` not apply to `OP_CHECKLOCKTIMEVERIFY` and `OP_CHECKSEQUENCEVERIFY`. This is a no-op as `UPGRADABLE_NOPS` is only set for mempool transactions, and those always have `SCRIPT_VERIFY_CHECKLOCKTIMEVERIFY` and `SCRIPT_VERIFY_CHECKSEQUENCEVERIFY` set as well. The advantage is that setting more flags now always results in a reduction in acceptable scripts (=softfork).
This results in a nice and testable property for validation, for which a new test is added.
This also means that the introduction of a new definition for a NOP or witness version will likely need the following procedure (example OP_NOP8 here)
* Remove OP_NOP8 from being affected by `SCRIPT_VERIFY_DISCOURAGE_UPGRADABLE_NOPS`.
* Add a `SCRIPT_VERIFY_DISCOURAGE_NOP8`, which only applies to `OP_NOP8`.
* Add a `SCRIPT_VERIFY_NOP8` which implements the new consensus logic.
* Before activation, add `SCRIPT_VERIFY_DISCOURAGE_NOP8` to the mempool flags.
* After activation, add `SCRIPT_VERIFY_NOP8` to both the mempool and consensus flags.

If a custom data directory is specified using `-datadir` argument, its existence is checked before the conf file is loaded. But if the conf file then specifies a different non-existent `datadir`, that isn't tested, and results in esoteric errors like:
EXCEPTION: N5boost10filesystem16filesystem_errorE
boost::filesystem::space: Operation not permitted
This just adds a check for the datadir existence at the end of `ReadConfigFile()`

[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
error code: -5
error message:
No such mempool transaction. Use -txindex to enable blockchain transaction queries. Use gettransaction for wallet transactions.

This should fix a very rare travis failure in zapwallettxes, but
is also more correct, as you can currently race
ReacceptWalletTransactions with stop RPC calls to get bitcoind to
(IMO) eroneously return a non-0 exit code.

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`.
