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.

NodeConn -> P2PConnection
NodeConnCB -> P2PInterface
|
|
This makes NodeConnCB a subclass of NodeConn, and
removes the need for the client code to know
anything about the implementation details of NodeConnCB.
NodeConn can now be swapped out for any other implementation
of a low-level connection without changing client code.
|
|
Change the helper methods to functions which take a node and a p2p
connection as arguments.

Changing __init__() -> set_test_params() in the tests should not have
applied to NodeConnCB-derived objects.

7148b74dc [tests] Functional tests must explicitly set num_nodes (John Newbery)

36b626867 [tests] TestNode: separate add_node from start_node (John Newbery)
be2a2ab6a [tests] fix - use rpc_timeout as rpc timeout (John Newbery)
Pull request description:
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__()
method. When they do that they need to call into super().__init__() as
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.
|
|
Separates the act of creating a TestNode object from starting the node.
The test_framework now keeps track of its list of TestNodes, and test
writers can call start_node() and stop_node() without having to update
the self.nodes list.

279fde5 Check for rpcuser/rpcpassword first then for cookie (Andrew Chow)
3ec5ad8 Add test for rpcuser/rpcpassword (Andrew Chow)
c53c983 Replace cookie auth in tests (Andrew Chow)

Better to check that rpcuser and rpcpassword exist then to check for
the cookie in the test framework.
Name an argument for consistency in p2p-segwit.py
|
|
Since rpcuser and rpcpassword are now deprecated, replace them with cookie auth.
Fix test failures with cookie auth

3e3c22f [tests] fix wait_for_inv() (John Newbery)

This test was passing because we never fetch blocks if we only receive
an inv and not the header (after 037159cebf1eae4445050cec029986514ed4e9e2),
and this test wasn't delivering the header.

2a52ae6 Remove duplicate method definitions in NodeConnCB subclasses (John Newbery)
52e15aa Adds helper functions to NodeConnCB (John Newbery)
Tree-SHA512: 2d7909eb85b3bde0fc3ebf133798eca21e561f4b2a2880937750820a42856cfb61fc94e30591c14ac13218bcfae0ebe7c5e8662a7b10f5b02470325c44a86cf1

* Refactor blocktools.py so that witness script creation is its own function
* Changed p2p-segwit to use new function
|
|
All Node classes in individual test cases subclass from NodeConnCB. Many
have duplicate definitions for methods that are defined in the base
class. This commit removes those duplicate definitions.
This commit removes ~290 lines of duplicate code.
|
|
sync_with_ping currently returns false if the timeout expires, and it is
the caller's responsibility to fail the test. However, none of the tests
currently assert on sync_with_ping()'s return code. This commit adds an
assert to sync_with_ping so the test will fail if the timeout expires.
This commit also removes all the duplicate implementations of
sync_with_ping() from the individual tests.
|
|
This commit merges the NodeConnCB and SingleNodeConnCB into a single
class (called NodeConnCB). The original intent for the NodeConnCB was to
be able to have a python 'mininode' connect to multiple running
bitcoinds. This has never been used and can be achieved more easily by
having multiple NodeConns backed by a common datastore if it is ever
needed.
The changes in mininode.py are just code moves (and merging the two
classes into a single class). The code changes in the individual test
cases are changing the subclasses to subclass from NodeConnCB instead of
SingleNodeConnCB. There is a lot of duplicate code in the subclasses
that can be removed in future commits.
