Andrew Poelstra 97bfbe790b Add a `clone` to script sat-checker to satisfy new soundness rules
This was actually a soundness bug waiting to happen fwiw...but I'm
still not so happy about it.

Andrew Poelstra e0c9844ff2 Make UtxoSet store (height, txo) pairs rather than just the raw txo
Will take some experimentation to see if this is what I want the API
to be, if the memory usage is acceptable, etc.

This will force a total reindex for wizards-wallet users.

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.

Andrew Poelstra 9f56b9c57f Fix wallet serialization to not use "" as a key anywhere
Turns out TOML does not support tables named "", so we instead encode
the accounts list as an array rather than a name-keyed hashmap. This
is fine since the account name is in the account structure itself
anyway.

Andrew Poelstra bc7077fac4 Encodable/Decodable improvements; add `user_enum` macro for string enums 2014-09-05 09:16:22 -05:00
Andrew Poelstra 331e555e4c Use `verify_raw` rather than `verify` to check signatures
`verify` cannot handle illegally padded signatures because it takes an object
of type `Signature`, which is a fixed-size type. This should have been part
of the previous commit --- an important lesson about running the unit tests
before every push!

Andrew Poelstra c25862a107 Change UtxoSet to use full TXID as key
Sorry, this is needed to enable proper txid/vout lookups for the address index.
This means any users of wizards-wallet need to rebuild their utxo sets, and
will also mean an increase in RAM usage.

Andrew Poelstra 9d283150c9 Fix GT/LT/GTEQ/LTEQ handling to not compare bools
I was trying to do something clever by making sure that the numeric
bounds were consistent with whatever ordering relation we were checking,
AND that the boolean values were also consistent...this is Wrong is the
case of negative numbers, and pointless anyway since I recently fixed
`set_bool_value`, `set_num_lo` and `set_num_hi` to update both numeric
and boolean information if possible, so they will always contain the
same info.

Andrew Poelstra d880bd1ccc Ensure execution state stack is empty at the start
We had a single `true` on the execution state stack, which would
allow scripts to have one more OP_ENDIF than they are allowed.

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.
