Pull request description:

  Replaces #11779 . Notes from that PR:

  > 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.

Pull request description:

  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.

John Newbery e9dfa9bccc [tests] Move version message sending from NodeConn to NodeConnCB
This commit moves the logic that sends a version message

John Newbery dad596fc37 [tests] Make NodeConnCB a subclass of NodeConn
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.

of a low-level connection without changing client code.

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.

  Second part of #11518.

  - First commit is almost entirely move-only
  - Second commit is mostly move-only, but also does a little tidying.

Merge #11468: [tests] Make comp test framework more debuggable
748157913 [tests] Make comp test framework more debuggable (John Newbery)

Pull request description:

  We should remove the comparison test framework entirely (see #10603).

  Until we do that, let's make it a bit more debuggable. Currently, if there's an assert in the framework, it's very difficult to track down where we are in the test generator. Make the logging a bit better to help with debugging.

a2be3b6 [net] Ignore getheaders requests for very old side blocks (Jim Posen)

Pull request description:

  Sending a getheaders message with an empty locator and a stop hash is a request for a single header by hash. The node will respond with headers for blocks not in the main chain as well as those in the main chain. To avoid fingerprinting, the node should, however, ignore requests for headers on side branches that are too old. This replicates the logic that currently exists for `getdata` requests for blocks.

  #11121 inadvertently broke the constructor for the `TestNode()` object in `p2p-segwit.py`, silently breaking at least one of the tests.

  Although the python code was raising exceptions due to a `TestNode()` object not existing (or having the right type), mininode was masking these from anyone running the test through the test_runner (like travis), because it catches all exceptions during message delivery and just prints a log message and continues.  Such "graceful" handling of errors is almost certainly something we don't want in our test suite, so the first commit here attempts to prevent that type of failure from ever being masked.

  The second commit fixes the particular bug in `p2p-segwit.py`.

Pull request description:

  Builds on top of #11117.

  This adds support for:
  * Creating BIP173 addresses for testing (through `addwitnessaddress`, though by default it still produces P2SH versions)
  * Sending to BIP173 addresses (including non-v0 ones)
  * Analysing BIP173 addresses (through `validateaddress`)

  It includes a reformatted version of the [C++ Bech32 reference code](https://github.com/sipa/bech32/tree/master/ref/c%2B%2B) and an independent implementation of the address encoding/decoding logic (integrated with CTxDestination). All BIP173 test vectors are included.

  Not included (and intended for other PRs):
  * Full wallet support for SegWit (which would include automatically adding witness scripts to the wallet during automatic keypool topup, SegWit change outputs, ...) [see #11403]
  * Splitting base58.cpp and tests/base58_tests.cpp up into base58-specific code, and "address encoding"-code [see #11372]
  * Error locating in UI for BIP173 addresses.

Merge #11323: mininode: add an optimistic write and disable nagle
1817398b3 mininode: add an optimistic write and disable nagle (Cory Fields)

Pull request description:

  Disclaimer: I'm not familiar with asyncore, so I'm unclear how safe this is. It works for me (tm).

  Because the poll/select loop may pause for 100msec before actually doing a send, and we have no way to force the loop awake, try sending from the calling thread if the queue is empty.

  Also, disable nagle as all sends should be either full messages or unfinished sends.

  This shaves an average of ~1 minute or so off of my accumulated runtime, and 10-15 seconds off of actual runtime.

Pull request description:

  There has been an example of p2p-leaktests.py failing on travis in the new service bits test (introduced in #11001 . It appeared to me that the previous p2p connections had not been fully disconnected before attempting to add new p2p connections.

  I've added a sleep and restarted the NetworkThread, but I don't know whether this will fix the problem, since I'm unable to reproduce the failure locally.

  @MarcoFalke - not sure what you want to do here? I don't think this change could make things any worse.

  Some additional tidyups after the introduction of TestNode:

  - commit 1 makes TestNode use the correct rpc timeout. This should have been included in #11077
  - commit 2 separates `add_node()` from `start_node()` as originally discussed here: https://github.com/bitcoin/bitcoin/pull/10556#discussion_r121161453 with @kallewoof . The test writer no longer needs to assign to `self.nodes` when starting/stopping nodes.
  - commit 3 adds a `set_test_params()` method, so individual tests don't need to override `__init__()` and call `super().__init__()`

Almost all test scripts currently need to override the __init__()

the base class does some generic initialization.

This commit makes the base class __init__() call into set_test_params()
method. Individual test cases can override set_test_params() to setup
their test parameters.

c6ec4358a [tests] Add bitcoin_cli.py test script (John Newbery)
b23549f6e [tests] add TestNodeCLI class for calling bitcoin-cli for a node (John Newbery)

Pull request description:

  We don't test bitcoin-cli at all. That means that we can miss inconsistencies between the bitcoin-cli client and the RPC interface, such as #10698 and #10747. It also means that the various bitcoin-cli options and features are untested and regressions could be silently introduced.

  Let's fix that.

  This PR adds bitcoin-cli testing in the python functional test_framework:

  1. Add a bitcoin_cli.py test script that tests bitcoin-cli. At the moment it only tests that the result of `getinfo` is the same if you run it as an RPC or through bitcoin-cli, but can easily be extended to test additional bitcoin-cli features

  **EDIT: `--usecli` option is moved to a separate PR. This PR now only covers the bitcoin_cli.py test.**

  2. ~Add a `--usecli` option to the test framework. This changes the test to use bitcoin-cli for all RPC calls instead of using direct HTTP requests. This is somewhat experimental. It works for most tests, but there are some cases where it can't work transparently because:~
  - ~the testcase is asserting on a specific error code, and bitcoin-cli returns a different error code from the direct RPC~
  - ~we're sending a very large RPC request (eg `submitblock`) and it can't be serialized into a shell bitcoin-cli call.~

  ~I think that even though `--usecli` doesn't work on all tests, it's still a useful experimental feature. Future potential enhancements:~
  - ~enhance the framework to automatically skip tests that are known to fail with bitcoin-cli if the `--usecli` option is used.~
  - ~run a subset of tests in Travis with `-usecli`~

  This builds on and requires the `TestNode` PR #10711 . As an aside, this is a good demonstration of how tidy it is to add additional features/interfaces now that test node logic/state is encapsulated in a TestNode class.

  Addresses #10791

  This moves `wait_until` to `util.py` to make it generally available to python tests.
  Also, `wait_until` now takes an optional lock that is acquired while testing the predicate.
  Previously the lock was always acquired, even when it was not necessary, cf. `disconnect_ban.py`.

John Newbery 2b4ea520b7 [tests] fix timeout issues from TestNode
Fixes a couple of bugs from the introduction of TestNode:

- test scripts were no longer able to specify a custom timeout for
starting a node. Therefore tests with nodes that take a long time to
start up (eg pruning.py) would fail.
- the test for whether a node has failed on start up was broken
by changing 'assert x is None' to 'assert not x'. Since
subprocess.poll() can return None (indicating the node is still running)
or 0 (indicating the node exited with return code 0), this was a
regression.

  Continues #10082

  TestNode is a class responsible for all state related to a bitcoind node
  under test. It stores local state, is responsible for tracking the
  bitcoind process and delegates unrecognised messages to the RPC
  connection.

  This commit changes start_nodes and stop_nodes to start and stop the
  bitcoind nodes in parallel, making test setup and teardown much faster.

  On my vm, this changeset reduces total test_runner runtime for the base set of tests
  (including building the cache) from 263s to 195s (a 25% speedup). Note that the time
  reported by test_runner does not include time spent building the cache:

John Newbery 7897338918 [tests] Introduce TestNode
TestNode is a class responsible for all state related to a bitcoind node
under test. It stores local state, is responsible for tracking the
bitcoind process and delegates unrecognised messages to the RPC
connection.

This commit changes start_nodes and stop_nodes to start and stop the
bitcoind nodes in parallel, making test setup and teardown much faster.

Merge #11023: [tests] Add option to attach a python debugger if functional test fails
cc5d38f4b Add option to attach a python debugger if test fails (John Newbery)

Pull request description:

  Adds a simple option to the test_framework to attach pdb if the test fails.

  Helpful for catching and debugging intermittent failures: Run the test in a loop with this option. The first failure will cause execution to pause and nodes will be left running for interactive debugging.

John Newbery 5e35cd94c1 [tests] Test disconnecting unsupported service bits logic.
In v0.15, we disconnect nodes that send us version messages with
unsupported service bits (1 << 5 and 1 << 7). This commit adds a test
that bitcoind will disconnect those nodes before August 1st 2018, and won't
disconnect those nodes after August 1st 2018.

Suhas Daftuar 176c021d08 [qa] Test non-atomic chainstate writes
Adds new functional test, dbcrash.py, which uses -dbcrashratio to exercise the
logic for recovering from a crash during chainstate flush.

dbcrash.py is added to the extended tests, as it may take ~10 minutes to run

Use _Exit() instead of exit() for crash simulation

This eliminates stderr output such as:
    terminate called without an active exception
or
    Assertion failed: (!pthread_mutex_destroy(&m)), function ~recursive_mutex, file /usr/local/include/boost/thread/pthread/recursive_mutex.hpp, line 104.

Eliminating the stderr output on crash simulation allows testing with
test_runner.py, which reports a test as failed if stderr is produced.

"without fully understanding the ramification of a command" -> "without fully understanding the ramifications of a command".

MarcoFalke 999923e4bb [qa] util: Check return code after closing bitcoind proc
This has no effect on the outcome of test cases, but
prints shorter and less confusing tracebacks on fails.

I.e. does not print an obvious "ConnectionRefusedError"
when shutting down the nodes due to an invalid return code.
