Make sure that the scripts of decoded transactions are valid scripts.
|
|
Added a function in CScript that checks if the script contains valid opcodes.
Add a test for that function

Such moves are used when reallocating vectors that contain them,
for example.

Thanks to Sergio Lerner for identifying this issue and suggesting this kind of solution.

Function is stl; std::equal just makes more sense.

- Replace NOP3 with CHECKSEQUENCEVERIFY (BIP112)
<nSequence> CHECKSEQUENCEVERIFY -> <nSequence>
- Fails if txin.nSequence < nSequence, allowing funds of a txout to be locked for a number of blocks or a duration of time after its inclusion in a block.
- Pull most of CheckLockTime() out into VerifyLockTime(), a local function that will be reused for CheckSequence()
- Add bitwise AND operator to CScriptNum
- Enable CHECKSEQUENCEVERIFY as a standard script verify flag
- Transactions that fail CSV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CSV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CSV for production use.

This adds two new constants, MAX_OPS_PER_SCRIPT and
MAX_PUBKEYS_PER_MULTISIG.
|
|
Previously only one PUSHDATA was allowed, needlessly limiting
applications such as matching OP_RETURN contents with bloom filters that
operate on a per-PUSHDATA level. Now any combination that passes
IsPushOnly() is allowed, so long as the total size of the scriptPubKey
is less than 42 bytes. (unchanged modulo non-minimal PUSHDATA encodings)
Also, this fixes the odd bug where previously the PUSHDATA could be
replaced by any single opcode, even sigops consuming opcodes such as
CHECKMULTISIG. (20 sigops!)
|
|
Allows IsPushOnly() to be applied to just part of the script for
OP_RETURN outputs.
|
|
These changes decode valid SIGHASH types on signatures in assembly (asm) representations of scriptSig scripts.
This squashed commit incorporates substantial helpful feedback from jtimon, laanwj, and sipa.

<nLockTime> CHECKLOCKTIMEVERIFY -> <nLockTime>
Fails if tx.nLockTime < nLockTime, allowing the funds in a txout to be
locked until some block height or block time in the future is reached.
Only the logic and unittests are implemented; this commit does not have
any actual soft-fork logic in it.
Thanks to Pieter Wuille for rebase.
Credit goes to Gregory Maxwell for the suggestion of comparing the
argument against the transaction nLockTime rather than the current
time/blockheight directly.

|
|
|
Will now be needed by CHECKLOCKTIMEVERIFY code.
|
|
While the existing numeric opcodes are all limited to 4-byte bignum
arguments, new opcodes will need different limits.

Also use the new flag as a standard rule, and replace the IsCanonicalPush
standardness check with it (as it is more complete).
