bip143: Rename witness_script to script_code
For p2wsh the scriptCode is the witness script, but for p2wpkh, it's the
equivalent legacy p2pkh output script.
The name scriptCode is used in the BIP, so it's less confusing.

Dr. Maxim Orlovsky 3c21e301aa Better RawNewtorkMessage deserealization from IO stream (#231)
Follow-up to https://github.com/rust-bitcoin/rust-bitcoin/pull/229

While working with remote peers over the network it is required to deserealize RawNetworkMessage from `TCPStream` to read the incoming messages. These messages can be partial – or one TCP packet can contain few of them. To make the library usable for such use cases, I have implemented the required functionality and covered it with unit tests.

Sample usage:
```rust
fn run() -> Result<(), Error> {
    // Opening stream to the remote bitcoind peer
    let mut stream = TcpStream::connect(SocketAddr::from(([37, 187, 0, 47], 8333));
    let start = SystemTime::now();

    // Constructing and sending `version` message to get some messages back from the remote peer
    let since_the_epoch = start.duration_since(UNIX_EPOCH)
        .expect("Time went backwards");
    let version_msg = message::RawNetworkMessage {
        magic: constants::Network::Bitcoin.magic(),
        payload: message::NetworkMessage::Version(message_network::VersionMessage::new(
            0,
            since_the_epoch.as_secs() as i64,
            address::Address::new(receiver, 0),
            address::Address::new(receiver, 0),
            0,
            String::from("macx0r"),
            0
        ))
    };
    stream.write(encode::serialize(&version_msg).as_slice())?;

    // Receiving incoming messages
    let mut buffer = vec![];
    loop {
        let result = StreamReader::new(&mut stream, None).read_messages();
        if let Err(err) = result {
            stream.shutdown(Shutdown::Both)?;
            return Err(Error::DataError(err))
        }
        for msg in result.unwrap() {
            println!("Received message: {:?}", msg.payload);
        }
    }
}
```

Sample output is the following:
```
Received message: Version(VersionMessage { version: 70015, services: 1037, timestamp: 1548637162, receiver: Address {services: 0, address: [0, 0, 0, 0, 0, 65535, 23536, 35968], port: 33716}, sender: Address {services: 1037, address: [0, 0, 0, 0, 0, 0, 0, 0], port: 0}, nonce: 1370726880972892633, user_agent: "/Satoshi:0.17.99/", start_height: 560412, relay: true })

```

This change also moves the secp256k1::Error wrapper from util::Error to

that are not related to consensus::encode.

Carl Dong b88f00c698 Add bitcoin_hashes dependency, rename some features
Because features and dependencies share the same namespace, and we want
to pass down the optional dependence on serde to bitcoin_hashes, we need
to rename the feature to something other than serde. Right now only
features can be passed down to dependencies.

Note that we could have also renamed the dependency to something like
serde-dep and kept the same feature name, however, dependency renaming
has only been available since cargo 0.27.0

Features that represent optional dependencies have been prefixed with
'use-'. The travis file has also been modified to conform to this
change.

Rename `TxOutRef` to `OutPoint` and use it in `TxIn`.
2018-08-20 18:18:00 +00:00
Jean Pierre Dudey 32631e44ad Rename `TxOutRef` to `OutPoint` and use it in `TxIn`.
Previously this structure was unused, it's now being used by the `TxIn`
structure to simplify the code a little bit and avoid confusions. Also
the rust-lightning source code has an `OutPoint` similar to this one
but with the `vout` index as an `u16` to avoid unsafe conversions.

I've added to new methods to `OutPoint`:

- `null`: Creates a new "null" `OutPoint`.
- `is_null`: Checks if the given `OutPoint` is null.

Jean Pierre Dudey 1b4aba1d80 Update serde to 1.0 and strason to 0.4
The `serde_struct_impl!` macro has been modified to be compatible
with the serde 1.0 crate, we use this macro and not the `serde_derive`
crate because the latter doesn't support Rust 1.14.0 which is shipped
on Debian stable and we should remain compatible with it.

Two new features were added:

- "serde": enables serialization/deserialization for common types, it pulls
the serde 1.0 dependency.
- "serde-decimal": enables serialization/deserialization for `UDecimal`/`Decimal`,
this pulls the strason 0.4 depdendency and the serde 1.0 dependency.

Carl Dong 4a5bf52ed9 Improve consistency for bip32::ChildNumber
There seemed to be some confusion as to whether the internal
represenation of a ChildNumber is supposed to be the index (0..2^31-1
for _both_ Normal and Hardened) or the actual number (0..2^31-1 for
Normal and 2^31..2^32-1 for Hardened). This commits fixes this
confusion.

- Make clear that the internal representation is the index rather
  than the actual number
- Make the internal representation non-public
- Provide methods for creating valid ChildNumbers
- Change relevant callers and tests to conform to this new ChildNumber

My rationale for using index rather than the actual number as internal
representation is that the difference between the two enum variants
already encode wether a ChildNumber is a normal one or a hardened one,
so the only bit of extra information left to be encoded is its index.

Savil Srivastava 933dcaeb82 [code hygiene] remove deprecated rustc-serialize
Addresses #96.

Turns out it was being used for hex encoding/decoding, so replaced that with the `hex` crate.

i chose to import the `decode` method as:
```
use hex::decode as hex_decode
```

so that it is clear to the reader what is being decoded when it is called. "decode" is such a generic sounding function name that it would get confusing otherwise.

Matt Corallo 0e1d927b47 Only provide the required TxIn to bip143 sighash_all.
This resolves an very unergonomic API by allowing iteration over a
Transaction being signed's inputs without needing to take a
conflicting reference to the transaction.

The API is still relateively unsafe in that its very easy to
generate bogus sighashes with it, but this is much better than it
was, and its not clear how to fix it further.

Matt Corallo a33f00621b Move witness inside of TxIn.
This is a rather large breaking API change, but is significantly
more sensible. In the "do not allow internal representation to
represent an invalid state" category, this ensures that witness
cannot have an length other than the number of inputs. Further,
it reduces vec propagation, which may help performance in some
cases by reducing allocs. Fianlly, this just makes more sense (tm).
Witness are a per-input field like the scriptSig, placing them
outside of the TxIn is just where they are serialized, not where
they logically belong.

Andrew Poelstra e05e6d2215 [BREAKING CHANGE] Drop UtxoSet
This code was unmaintained, is unlikely to work on the majority of systems
(since it holds the whole utxoset in RAM, and not in a terribly efficient
manner), and has a dependency on `eventual` which has been broken for a
long time.

The library no longer compiles on nightly because of this, and without any
known usecases for `UtxoSet`, nor good ability to test it, I'm simply
removing the code.

I recommend anyone who cares about this extracts the code from the previous
commit and creates a new crate. It should be more featureful anyway, e.g.
support a backing store.

be used in the actual library (in particular, TxOutRef.index is a usize for
convenience while TxIn.prev_index is a u32 for correct consensus encoding,
so there is not redundancy here).

Andrew Poelstra 3491c5057e Make contracthashtool check that the number of keys matches the template's requirement
This is easy to satisfy given that the template-to-script code takes a
slice of keys. Just do &keys[..n_keys] if you have too many keys. (If
you have too few you're SOL no matter what.) This way we can catch
likely configuration errors without putting much of a burden on users
who legitimately have more keys than the template requires.

Also add a method required_keys() to Template so that users can check
how many keys they ought to have.

Does not do stuff like validating the form of contracts, since this seems like

Work is stalled on some other library work (to give better lifetime

committing here.

Also all the indenting is done, so there should be no more massive

Andrew Poelstra ef11e8273b Destroy socket listener on error rather than trying to reconnect; add #derivings
Reconnecting an existing socket simply was not working; the Rust socket
did not expose any methods for reconnection, so I simply tried calling
connect() again. As near as I can tell, this was a no-op --- which makes
sense because both the sending and receiving threads had their own copy
of the Socket, and it's not clear what the synchronization behaviour
should have been.

Instead if the connection fails, we relay this information to the main
thread, wait for an acknowledgement, then simply destroy the listening
thread. The caller can then simply call `start()` again.

anyway.

same info.

Andrew Poelstra 340b569c73 Add much more agressive provably-false checker
Now unspendable outs are determined by attempting to create a minimal
satisfying input script. If this can't be done, the output is unspendable.
(Unfortunately this "minimal satisfying script" is not (yet) something
that can be shown to the user, since it is more a bundle of constraints
than actual data pushes.)

Current limitations:
  - OP_ADD and friends mean the checker gives the script a free pass.
    There is no fundamental reason for this, I just didn't get to it
    yet.

  - Pubkeys are checked for DER encoding but signatures aren't. This
    is because secp256k1 exposes a method for pubkeys, but not one
    for sigs :). Signatures are loosely length checked.

A breaking change by the array newtyping is that Show for Sha256dHash
now outputs the slice Show. You have to use `{:x}` to get the old hex
output.

other hashes, so I'm committing here as a checkpoint before doing all
that.

Andrew Poelstra 2986e1f983 Fix for new partial-move rules; swap hash le_hex_string and be_hex_string
I noticed that the little/big endian hex string functions for Sha256dHash
did not match my intuition. What we should have is that the raw bytes
correspond to a little-endian representation (since we convert to Uint256
by transmuting, and Uint256's have little-endian representation) while
the reversed raw bytes are big-endian.

This means that the output from `sha256sum` is "little-endian", while the
standard "zeros on the left" output from bitcoind is "big-endian". This
is correct since we think of blockhashes as being "below the target" when
they have lots of zeros on the left, and we also notice that when hashing
Bitcoin objects with sha256sum that the output hashes are always reversed.

These two functions le_hex_string and be_hex_string should really not be
used outside of the library; the Encodable trait should give access to a
"big endian" representation while ConsensusEncodable gives access to a
"little endian" representation. That way we describe the split in terms
of user-facing/consensus code rather than big/little endian code, which
is a better way of thinking about it. After all, a hash is a collection
of bytes, not a number --- it doesn't have an intrinsic endianness.

Oh, and by the way, to compute a sha256d hash from sha256sum, you do

  echo -n 'data' | sha256sum | xxd -r -p | sha256dsum

Andrew Poelstra 474d04d154 Manually implement Encodable/Decodable/Show for Network
Since TOML will not encode C-like enums as strings, we do it
ourselves. This is also worthwhile so that we can get the
lowercase "bitcoin" and "testnet" as encodings for the actual
enum values, which are more verbose and camel case.
2014-08-03 06:29:19 -07:00
Andrew Poelstra a6eb33efd0 Actually encode network message
A pretty serious oversight :) this was not noticed because I was
simultaneously dealing with a serious tcp connection bug in rustc,
and I had thought bitcoind's angry disconnects were a further
symptom of that.

Andrew Poelstra a34f2642f1 Implement ToJson for BlockHeader
I think this is what I want to do for everything json-visible...perhaps
I will not be able to keep the macro for it though, since there are
some clever variations on it (e.g. blocks should have their header's
hash as a field, txes should appear as txids unless vebose output is
requested, etc.)

This was causing a mystery crash. Fixed.

Andrew Poelstra 1be45395da Store TxOuts directly in UtxoSet rather than in Boxes
This gives a significant speedup during deserialization since we
don't have to allocate for every output.

Andrew Poelstra b5c25ff768 Distinguish between network/decode errors in network message decode
It is now visible that EOF (i.e. peer hung up) is interpreted
as a message decode error. Probably what we want to do is reset
the connection on any error. TODO

Andrew Poelstra 46969b3396 Replace PatriciaTree with HashMap for UTXO set
We get a speed up (~5%) and memory savings (~10%) on initial sync from
using a HashMap, though it's hard to tell precisely how much savings
because it's quite nonlinear.

I haven't tested de/serialization. Some work needs to be done there to
split up the UTXO set since it takes forever to saveload.

Andrew Poelstra 54e4ea4586 Rename Serializable::hash() to Serializable::bitcoin_hash()
We were conflicting with the Rust stdlib trait Hash, which is used
by various datastructures which need a general hash. Also implement
Hash for Sha256dHash so that we can use bitcoin hashes as keys for
such data structures.
