Pull request description:
Introducing the wallet of the glorious future (again): native descriptor wallets. With native descriptor wallets, addresses are generated from descriptors. Instead of generating keys and deriving addresses from keys, addresses come from the scriptPubKeys produced by a descriptor. Native descriptor wallets will be optional for now and can only be created by using `createwallet`.
Descriptor wallets will store descriptors, master keys from the descriptor, and descriptor cache entries. Keys are derived from descriptors on the fly. In order to allow choosing different address types, 6 descriptors are needed for normal use. There is a pair of primary and change descriptors for each of the 3 address types. With the default keypool size of 1000, each descriptor has 1000 scriptPubKeys and descriptor cache entries pregenerated. This has a side effect of making wallets large since 6000 pubkeys are written to the wallet by default, instead of the current 2000. scriptPubKeys are kept only in memory and are generated every time a descriptor is loaded. By default, we use the standard BIP 44, 49, 84 derivation paths with an external and internal derivation chain for each.
Descriptors can also be imported with a new `importdescriptors` RPC.
Native descriptor wallets use the `ScriptPubKeyMan` interface introduced in #16341 to add a `DescriptorScriptPubKeyMan`. This defines a different IsMine which uses the simpler model of "does this scriptPubKey exist in this wallet". Furthermore, `DescriptorScriptPubKeyMan` does not have watchonly, so with native descriptor wallets, it is not possible to have a wallet with both watchonly and non-watchonly things. Rather a wallet with `disable_private_keys` needs to be used for watchonly things.
A `--descriptor` option was added to some tests (`wallet_basic.py`, `wallet_encryption.py`, `wallet_keypool.py`, `wallet_keypool_topup.py`, and `wallet_labels.py`) to allow for these tests to use descriptor wallets. Additionally, several RPCs are disabled for descriptor wallets (`importprivkey`, `importpubkey`, `importaddress`, `importmulti`, `addmultisigaddress`, `dumpprivkey`, `dumpwallet`, `importwallet`, and `sethdseed`).

Adds a --descriptors option globally to the test framework. This will
make the test create and use descriptor wallets. However some tests may
not work with this.
Some tests are modified to work with --descriptors and run with that
option in test_runer:
* wallet_basic.py
* wallet_encryption.py
* wallet_keypool.py
* wallet_keypool_topup.py
* wallet_labels.py
* wallet_avoidreuse.py
RPCOverloadWrapper overloads some deprecated or disabled RPCs with
an implementation using other RPCs to avoid having a ton of code churn
around replacing those RPCs.
fa03713e13 test: Properly raise FailedToStartError when rpc shutdown before warmup finished (take 2) (MarcoFalke)
Pull request description:
actually (?) fix#18561
See most recent traceback https://travis-ci.org/github/bitcoin/bitcoin/jobs/674668692#L7062
I believe the reason the error is still there is that ConnectionResetError is derived from OSError:
ConnectionResetError(ConnectionError(OSError))
And IOError is an alias for OSError since python 3.3, see https://docs.python.org/3/library/exceptions.html#IOError
So fix that by renaming IOError to the alias OSError and move the less specific catch clause down a few lines.

13782b8ba8 docs: add perf section to developer docs (James O'Beirne)
58180b5fd4 tests: add utility to easily profile node performance with perf (James O'Beirne)
Pull request description:
Adds a context manager to easily (and selectively) profile node performance during functional test execution using `perf`.
While writing some tests, I encountered some odd bitcoind slowness. I wrote up a utility (`TestNode.profile_with_perf`) that generates performance diagnostics for a node by running `perf` during the execution of a particular region of test code.
`perf` usage is detailed in the excellent (and sadly unmerged) https://github.com/bitcoin/bitcoin/pull/12649; all due props to @eklitzke.
### Example
```python
with node.profile_with_perf("large-msgs"):
for i in range(200):
node.p2p.send_message(some_large_msg)
node.p2p.sync_with_ping()
```
This generates a perf data file in the test node's datadir (`/tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data`).
Running `perf report` generates nice output about where the node spent most of its time while running that part of the test:
```bash
$ perf report -i /tmp/testtxmpod0y/node0/node-0-TestName-large-msgs.perf.data --stdio \
| c++filt \
| less
# To display the perf.data header info, please use --header/--header-only options.

When running tests with --usecli, unify the conversion from argument objects to
strings using a new function arg_to_cli(). This fixes boolean arguments when
using named arguments.
Also use json.dumps() to get the string values for arguments that are dicts and
lists so that bitcoind's JSON parser does not become confused.
Introduces `TestNode.profile_with_perf()` context manager which
samples node execution to produce profiling data.
Also introduces a test framework flag, `--perf`, which will run
perf on all nodes for the duration of a given test.

02e1e4eff6 rpc: Add wait argument to stop (João Barbosa)
Pull request description:
Fixes#11777. Reverts #11006. Replaces #13501.
With this change the HTTP server will exit gracefully, meaning that all requests will finish processing and sending the response, even if this means to wait more than 2 seconds (current time allowed to exit the event loop).
Another small change is that connections are accepted even when the server is stopping, but HTTP requests are rejected. This can be improved later, especially if chunked replies are implemented.
Briefly, before this PR, this is the order or events when a request arrives (RPC `stop`):
1. `bufferevent_disable(..., EV_READ)`
2. `StartShutdown()`
3. `evhttp_del_accept_socket(...)`
4. `ThreadHTTP` terminates (event loop exits) because there are no active or pending events thanks to 1. and 3.
5. client doesn't get the response thanks to 4.
This can be verified by applying
```diff
// Event loop will exit after current HTTP requests have been handled, so
// this reply will get back to the client.
StartShutdown();
+ MilliSleep(2000);
return "Bitcoin server stopping";
}
```
and checking the log output:
```
Received a POST request for / from 127.0.0.1:62443
ThreadRPCServer method=stop user=__cookie__

... sleep 2 seconds ...

```
For this reason point 3. is moved right after all HTTP workers quit. In that moment HTTP replies are queued in the event loop which keeps spinning util all connections are closed. In order to trigger the server side close with keep alive connections (implicit in HTTP/1.1) the header `Connection: close` is sent if shutdown was requested. This can be tested by
```
bitcoind -regtest
nc localhost 18443
POST / HTTP/1.1
Authorization: Basic ...
Content-Type: application/json
Content-Length: 44
{"jsonrpc": "2.0","method":"stop","id":123}
```
Summing up, this PR:
- removes explicit event loop exit — event loop exits once there are no active or pending events
- changes the moment the listening sockets are removed — explained above
- sends header `Connection: close` on active requests when shutdown was requested which is relevant when it's a persistent connection (default in HTTP 1.1) — libevent is aware of this header and closes the connection gracefully
- removes event loop explicit break after 2 seconds timeout

Adds a utility to get resident set size memory usage for a test
node and a context manager that allows assertions based upon
maximum memory use increase.
This requires a small changes to a few tests, but means that
deterministic addresses will always be imported (unless setup_nodes
behaviour is explicitly overridden).
Adds a generate() method to the TestNode class in the test framework.
This method intercepts calls to generate, imports a dewterministic
private key to the node and then calls generatetoaddress to generate the
block to that address.
Note that repeated calls to importprivkey for the same private keys are
no-ops, so it's fine to call the generate() method many times.

Pull request description:
This is the replacement for #11678 which implements @ryanofsky's [suggestion](https://github.com/bitcoin/bitcoin/pull/11678#pullrequestreview-76464511).
Shutting down the software was to prevent the BDB environment from writing unencrypted private keys to disk in the database log files, as was noted [here](https://bitcointalk.org/index.php?topic=51474.msg616068#msg616068). This PR replaces the shutdown behavior with a CDBEnv flush, close, and reopen which achieves the same effect: everything is cleanly flushed and closed, the log files are removed, and then the environment reopened to continue normal operation.
To ensure that no unencrypted private keys are in the log files after encrypting the wallet, I wrote [this script](https://gist.github.com/achow101/7f7143e6c3d3fdc034d3470e72823e9d) to pull private keys from the original wallet file and searches for these keys in the log files (note that you will have to change your file paths to make it work on your own machine).
As for concerns about private keys being written to slack space or being kept in memory, these behaviors no longer exist after the original wallet encryption PR and the shutting down solution from 2011.

Pull request description:
### qa: Close stdout and stderr file when node stops
Since these files are potentially deleted by the test framework for cleanup, they should be closed first. Otherwise this will lead to errors on Windows when the tests finish successfully.
Side note: After the patch, it is no longer possible to reopen the file on Windows (see https://docs.python.org/3/library/tempfile.html#tempfile.NamedTemporaryFile)
### qa: Run gen_rpcauth with sys.executable
Similar to `test_runner.py`, the `sys.executable` needs to be passed down into subprocesses to pass on native Windows. (Should have no effect on Linux)
### qa: Use files for stdout/stderr to support Windows
It seems that using PIPE is not supported on Windows. Also, it is easier to just use the files that capture the stdout and stderr within the test node class.

75d0e4c544 [qa] Delete cookie file before starting node (Suhas Daftuar)
Pull request description:
When a node is restarted during a test after an unclean shutdown (such
as with -dbcrashratio), it's possible an old cookie file was left
behind. This can cause a race condition when restarting the node, where
the test framework might try to connect using credentials from the
old cookie file, just as the node will generate new credentials and
overwrite the old file.
Delete any such cookie file if present prior to startup.

If a cookie file exists in a datadir prior to node startup, it must have
been leftover from a prior unclean shutdown. As bitcoind will overwrite
it anyway, delete it before starting up to prevent the test framework
from inadvertently trying to connect using stale credentials.

Commit c53c9831ee introduced the utility function `get_datadir_path`, however not all places in the code use this util function. Using the util function everywhere makes it easier to review pull requests related to the datadir.
This commit replaces datadir path creation with the `datadir` member of `TestNode`, which itself uses `get_datadir_path`.

fae1374 qa: Allow for partial_match when checking init error (MarcoFalke)
5812273 [Tests] Require exact match in assert_start_raises_init_eror() (John Newbery)
0ec08a6 [Tests] Move assert_start_raises_init_error method to TestNode (John Newbery)
Pull request description:
Extracted from #12379, because the changes are important on their own.
This allows for exact testing, since the match can be specified with a strict regex. Internal details (such as exact formatting of the error message) can still be fuzzed away by regex wildcards.

Prevents OSX firewall allow-this-application-to-accept-inbound-connections
permission popups and is generally safer.
To prevent binding to 127.0.0.1, set self.bind_to_localhost_only = False.
fae7b14a04 qa: Make TestNodeCLI command optional in send_cli (MarcoFalke)
ffffb10a9f qa: Rename cli.args to cli.options (MarcoFalke)
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.

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.
test_framework accepts a new --usecli parameter. Running the test with
this parameter will cause all RPCs to be sent through bitcoin-cli rather
than directly over http. By default, individual test cases do not
support --usecli, and self.supports_cli must be set to True in the
set_test_params method.
We can make supports_cli default to True in future once we know which
tests will fail with use_cli.
Change TestNodeCLI.__call__() to return a new instance instead of modifying the
existing instance. This way, it's possible to create different cli objects that
have their own options (for example -rpcwallet options to connect to different
wallets), and options set for a single call (`node.cli(options).method(args)`)
will no longer leak into future calls.
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.
