Andrew Poelstra 66eb08aab5 [BREAKING CHANGE] Make `script::Builder` implement the actual Builder pattern
Rather than having methods taking &mut self, have them consume self
and return another Builder, so that methods can be chained.

Bump major version number.

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.

Andrew Poelstra ed34bb30f1 Add support for deserializing a script into a contracthash template
This is something Matt's contracthashtool does, so to copy its functionality
I need to support it. And it also seems generally useful.

Andrew Poelstra 16e2a3519b Implement basic contract-hash support
Does not do stuff like validating the form of contracts, since this seems like
more of an application thing. Does not even distinguish a "nonce", just assumes
the contract has whatever uniqueness is needed baked in.

Andrew Poelstra adaf50a408 *** ALL TESTS PASS WITH RUSTC HEAD ***
There is still a lot of work to do modernizing the library, but the code
compiles cleanly with all unit tests passing now. Probably not much can
be done now until wizards-wallet is in better shape and the library is
actually in use.

Andrew Poelstra e5a3e84c41 Checkpoint commit (nope, not yet to small commit sizes :))
This is mostly fixing compile errors in `cargo test`. We are down
to 3 in `cargo build` and 14 in `cargo test`, at least for this
round.

Andrew Poelstra 08a20f8764 Checkpoint commit
Work is stalled on some other library work (to give better lifetime
requirements on `eventual::Future` and avoid some unsafety), so
committing here.

There are only three errors left in this round :)

Also all the indenting is done, so there should be no more massive
rewrite commits. Depending how invasive the lifetime-error fixes
are, I may even be able to do sanely sized commits from here on.

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.

Andrew Poelstra 6bf553c6fe Add BIP32 key support; unify array newtyping; improve base58 trait
Sorry for so many things in one commit ... it was an iterative
process depending as I worked on BIP32 to get the other stuff
working. (And I was too lazy to separate it out after the fact.)

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.

Andrew Poelstra ecdb750148 Implement script except for crypto opcodes, replace zero_hash by Default
Looks like to implement the crypto opcodes I may need to switch from
rust-crypto to rust-openssl.. or implement RIPEMD-160 for rust-crypto.
In either case I will need to generalize the hash.rs stuff to support
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
2014-08-03 14:52:59 -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 a2ce000b2b Revamp Serializable interface to be similar to Encoder/Encodable
This is a massive simplification, fixes a couple endianness bugs (though
not all of them I don't think), should give a speedup, gets rid of the
`serialize_iter` crap.
2014-08-01 09:01:39 -07:00
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.)

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.
2014-07-20 16:52:00 -07:00
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.
