"""Test the importmulti RPC.
Test importmulti by generating keys on node0, importing the scriptPubKeys and
addresses on node1 and then testing the address info for the different address
variants.
- `get_key()` and `get_multisig()` are called to generate keys on node0 and
return the privkeys, pubkeys and all variants of scriptPubKey and address.
- `test_importmulti()` is called to send an importmulti call to node1, test
success, and (if unsuccessful) test the error code and error message returned.
- `test_address()` is called to call getaddressinfo for an address on node1
and test the values returned."""

"""Test behavior of headers messages to announce blocks.
Setup:
- Two nodes:
- node0 is the node-under-test. We create two p2p connections to it. The
first p2p connection is a control and should only ever receive inv's. The
second p2p connection tests the headers sending logic.
- node1 is used to create reorgs.
test_null_locators
==================
Sends two getheaders requests with null locator values. First request's hashstop
value refers to validated block, while second request's hashstop value refers to
a block which hasn't been validated. Verifies only the first request returns
headers.
test_nonnull_locators
=====================
Part 1: No headers announcements before "sendheaders"
a. node mines a block [expect: inv]
send getdata for the block [expect: block]
b. node mines another block [expect: inv]
send getheaders and getdata [expect: headers, then block]
c. node mines another block [expect: inv]
peer mines a block, announces with header [expect: getdata]
d. node mines another block [expect: inv]
Part 2: After "sendheaders", headers announcements should generally work.
a. peer sends sendheaders [expect: no response]
peer sends getheaders with current tip [expect: no response]
b. node mines a block [expect: tip header]
c. for N in 1, ..., 10:
* for announce-type in {inv, header}
- peer mines N blocks, announces with announce-type
[ expect: getheaders/getdata or getdata, deliver block(s) ]
- node mines a block [ expect: 1 header ]
Part 3: Headers announcements stop after large reorg and resume after getheaders or inv from peer.
- For response-type in {inv, getheaders}
* node mines a 7 block reorg [ expect: headers announcement of 8 blocks ]
* node mines an 8-block reorg [ expect: inv at tip ]
* peer responds with getblocks/getdata [expect: inv, blocks ]
* node mines another block [ expect: inv at tip, peer sends getdata, expect: block ]
* node mines another block at tip [ expect: inv ]
* peer responds with getheaders with an old hashstop more than 8 blocks back [expect: headers]
* peer requests block [ expect: block ]
* node mines another block at tip [ expect: inv, peer sends getdata, expect: block ]
* peer sends response-type [expect headers if getheaders, getheaders/getdata if mining new block]
* node mines 1 block [expect: 1 header, peer responds with getdata]
Part 4: Test direct fetch behavior
a. Announce 2 old block headers.
Expect: no getdata requests.
b. Announce 3 new blocks via 1 headers message.
Expect: one getdata request for all 3 blocks.
(Send blocks.)
c. Announce 1 header that forks off the last two blocks.
Expect: no response.
d. Announce 1 more header that builds on that fork.
Expect: one getdata request for two blocks.
e. Announce 16 more headers that build on that fork.
Expect: getdata request for 14 more blocks.
f. Announce 1 more header that builds on that fork.
Expect: no response.
Part 5: Test handling of headers that don't connect.
a. Repeat 10 times:
1. Announce a header that doesn't connect.
Expect: getheaders message
2. Send headers chain.
Expect: getdata for the missing blocks, tip update.
b. Then send 9 more headers that don't connect.
Expect: getheaders message each time.
c. Announce a header that does connect.
Expect: no response.
d. Announce 49 headers that don't connect.
Expect: getheaders message each time.
e. Announce one more that doesn't connect.
Expect: disconnect.

bitcoin/test | bitcoin/test/functional/test-shell.md | Test Shell for Interactive Environments
=========================================
This document describes how to use the `TestShell` submodule in the functional
test suite.
The `TestShell` submodule extends the `BitcoinTestFramework` functionality to
external interactive environments for prototyping and educational purposes. Just
like `BitcoinTestFramework`, the `TestShell` allows the user to:
* Manage regtest bitcoind subprocesses.
* Access RPC interfaces of the underlying bitcoind instances.
* Log events to the functional test logging utility.
The `TestShell` can be useful in interactive environments where it is necessary
to extend the object lifetime of the underlying `BitcoinTestFramework` between
user inputs. Such environments include the Python3 command line interpreter or
[Jupyter](https://jupyter.org/) notebooks running a Python3 kernel.
## 1. Requirements
* Python3
* `bitcoind` built in the same repository as the `TestShell`.
## 2. Importing `TestShell` from the Bitcoin Core repository
We can import the `TestShell` by adding the path of the Bitcoin Core
`test_framework` module to the beginning of the PATH variable, and then
importing the `TestShell` class from the `test_shell` sub-package.
```
>>> import sys
>>> sys.path.insert(0, "/path/to/bitcoin/test/functional")
>>> from test_framework.test_shell import TestShell
```
The following `TestShell` methods manage the lifetime of the underlying bitcoind
processes and logging utilities.
* `TestShell().setup()`
* `TestShell().shutdown()`
The `TestShell` inherits all `BitcoinTestFramework` members and methods, such
as:
* `TestShell().nodes[index].rpc_method()`
* `TestShell().log.info("Custom log message")`
The following sections demonstrate how to initialize, run, and shut down a
`TestShell` object.
## 3. Initializing a `TestShell` object
```
>>> test = TestShell().setup(num_nodes=2, setup_clean_chain=True)
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Initializing test directory /path/to/bitcoin_func_test_XXXXXXX
```
The `TestShell` forwards all functional test parameters of the parent
`BitcoinTestFramework` object. The full set of argument keywords which can be
used to initialize the `TestShell` can be found in [section
#6](#custom-testshell-parameters) of this document.
**Note: Running multiple instances of `TestShell` is not allowed.** Running a
single process also ensures that logging remains consolidated in the same
temporary folder. If you need more bitcoind nodes than set by default (1),
simply increase the `num_nodes` parameter during setup.
```
>>> test2 = TestShell().setup()
TestShell is already running!
```
## 4. Interacting with the `TestShell`
Unlike the `BitcoinTestFramework` class, the `TestShell` keeps the underlying
Bitcoind subprocesses (nodes) and logging utilities running until the user
explicitly shuts down the `TestShell` object.
During the time between the `setup` and `shutdown` calls, all `bitcoind` node
processes and `BitcoinTestFramework` convenience methods can be accessed
interactively.
**Example: Mining a regtest chain**
By default, the `TestShell` nodes are initialized with a clean chain. This means
that each node of the `TestShell` is initialized with a block height of 0.
```
>>> test.nodes[0].getblockchaininfo()["blocks"]
0
```
We now let the first node generate 101 regtest blocks, and direct the coinbase
rewards to a wallet address owned by the mining node.
```
>>> test.nodes[0].createwallet('default')
{'name': 'default', 'warning': 'Empty string given as passphrase, wallet will not be encrypted.'}
>>> address = test.nodes[0].getnewaddress()
>>> test.generatetoaddress(test.nodes[0], 101, address)
['2b98dd0044aae6f1cca7f88a0acf366a4bfe053c7f7b00da3c0d115f03d67efb', ...
```
Since the two nodes are both initialized by default to establish an outbound
connection to each other during `setup`, the second node's chain will include
the mined blocks as soon as they propagate.
```
>>> test.nodes[1].getblockchaininfo()["blocks"]
101
```
The block rewards from the first block are now spendable by the wallet of the
first node.
```
>>> test.nodes[0].getbalance()
Decimal('50.00000000')
```
We can also log custom events to the logger.
```
>>> test.nodes[0].log.info("Successfully mined regtest chain!")
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework.node0 (INFO): Successfully mined regtest chain!
```
**Note: Please also consider the functional test
[readme](../test/functional/README.md), which provides an overview of the
test-framework**. Modules such as
[key.py](../test/functional/test_framework/key.py),
[script.py](../test/functional/test_framework/script.py) and
[messages.py](../test/functional/test_framework/messages.py) are particularly
useful in constructing objects which can be passed to the bitcoind nodes managed
by a running `TestShell` object.
## 5. Shutting the `TestShell` down
Shutting down the `TestShell` will safely tear down all running bitcoind
instances and remove all temporary data and logging directories.
```
>>> test.shutdown()
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Stopping nodes
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Cleaning up /path/to/bitcoin_func_test_XXXXXXX on exit
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Tests successful
```
To prevent the logs from being removed after a shutdown, simply set the
`TestShell().options.nocleanup` member to `True`.
```
>>> test.options.nocleanup = True
>>> test.shutdown()
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Stopping nodes
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Not cleaning up dir /path/to/bitcoin_func_test_XXXXXXX on exit
20XX-XX-XXTXX:XX:XX.XXXXXXX TestFramework (INFO): Tests successful
```
The following utility consolidates logs from the bitcoind nodes and the
underlying `BitcoinTestFramework`:
* `/path/to/bitcoin/test/functional/combine_logs.py
'/path/to/bitcoin_func_test_XXXXXXX'`
## 6. Custom `TestShell` parameters
The `TestShell` object initializes with the default settings inherited from the
`BitcoinTestFramework` class. The user can override these in
`TestShell().setup(key=value)`.
**Note:** `TestShell().reset()` will reset test parameters to default values and
can be called after the TestShell is shut down.
| Test parameter key | Default Value | Description |
|---|---|---|
| `bind_to_localhost_only` | `True` | Binds bitcoind RPC services to `127.0.0.1` if set to `True`.|
| `cachedir` | `"/path/to/bitcoin/test/cache"` | Sets the bitcoind datadir directory. |
| `chain` | `"regtest"` | Sets the chain-type for the underlying test bitcoind processes. |
| `configfile` | `"/path/to/bitcoin/test/config.ini"` | Sets the location of the test framework config file. |
| `coveragedir` | `None` | Records bitcoind RPC test coverage into this directory if set. |
| `loglevel` | `INFO` | Logs events at this level and higher. Can be set to `DEBUG`, `INFO`, `WARNING`, `ERROR` or `CRITICAL`. |
| `nocleanup` | `False` | Cleans up temporary test directory if set to `True` during `shutdown`. |
| `noshutdown` | `False` | Does not stop bitcoind instances after `shutdown` if set to `True`. |
| `num_nodes` | `1` | Sets the number of initialized bitcoind processes. |
| `perf` | False | Profiles running nodes with `perf` for the duration of the test if set to `True`. |
| `rpc_timeout` | `60` | Sets the RPC server timeout for the underlying bitcoind processes. |
| `setup_clean_chain` | `False` | A 200-block-long chain is initialized from cache by default. Instead, `setup_clean_chain` initializes an empty blockchain if set to `True`. |
| `randomseed` | Random Integer | `TestShell().options.randomseed` is a member of `TestShell` which can be accessed during a test to seed a random generator. User can override default with a constant value for reproducible test runs. |
| `supports_cli` | `False` | Whether the bitcoin-cli utility is compiled and available for the test. |
| `tmpdir` | `"/var/folders/.../"` | Sets directory for test logs. Will be deleted upon a successful test run unless `nocleanup` is set to `True` |
| `trace_rpc` | `False` | Logs all RPC calls if set to `True`. |
| `usecli` | `False` | Uses the bitcoin-cli interface for all bitcoind commands instead of directly calling the RPC server. Requires `supports_cli`. |

# The balance is indeed "trusted" and "confirmed" insofar as removing

Utilities for working directly with the wallet's BDB database file
This is specific to the configuration of BDB used in this project:
- pagesize: 4096 bytes
- Outer database contains single subdatabase named 'main'
- btree
- btree leaf pages
Each key-value pair is two entries in a btree leaf. The first is the key, the one that follows
is the value. And so on. Note that the entry data is itself not in the correct order. Instead
entry offsets are stored in the correct order and those offsets are needed to then retrieve
the data itself.
Page format can be found in BDB source code dbinc/db_page.h
This only implements the deserialization of btree metadata pages and normal btree pages. Overflow
pages are not implemented but may be needed in the future if dealing with wallets with large
transactions.
`db_dump -da wallet.dat` is useful to see the data in a wallet.dat BDB file

"""HTTP proxy for opening RPC connection to bitcoind.
AuthServiceProxy has the following improvements over python-jsonrpc's
ServiceProxy class:
- HTTP connections persist for the life of the AuthServiceProxy object

- sends protocol 'version', per JSON-RPC 1.1
- sends proper, incrementing 'id'
- sends Basic HTTP authentication headers
- parses all JSON numbers that look like floats as Decimal
