2016-05-05Merge #7907: Optimize and Cleanup CScript::FindAndDeleteWladimir J. van der Laan
d1d7775 Improve worst-case behavior of CScript::FindAndDelete (Patrick Strateman) e2a30bc Unit test for CScript::FindAndDelete (Gavin Andresen) c0f660c Replace c-style cast with c++ style static_cast. (Patrick Strateman) ec9ad5f Replace memcmp with std::equal in CScript::FindAndDelete (Patrick Strateman)

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

2016-04-19Replace memcmp with std::equal in CScript::FindAndDeletePatrick Strateman
Function is stl; std::equal just makes more sense.
2016-02-14BIP112: Implement CHECKSEQUENCEVERIFYMark Friedenbach
- 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.
2015-10-01Accept any sequence of PUSHDATAs in OP_RETURN outputsPeter Todd
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!)
2015-10-01Add IsPushOnly(const_iterator pc)Peter Todd
Allows IsPushOnly() to be applied to just part of the script for OP_RETURN outputs.
2015-07-30Resolve issue 3166.mruddy
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.

ffd75ad Enable CHECKLOCKTIMEVERIFY as a standard script verify flag (Peter Todd) bc60b2b Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65) (Peter Todd) 48e9c57 Move LOCKTIME_THRESHOLD to src/script/script.h (Peter Todd) 99088d6 Make CScriptNum() take nMaxNumSize as an argument (Peter Todd)
2015-06-21Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65)Peter Todd
<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.

2015-05-09Move LOCKTIME_THRESHOLD to src/script/script.hPeter Todd
Will now be needed by CHECKLOCKTIMEVERIFY code.
2015-05-09Make CScriptNum() take nMaxNumSize as an argumentPeter Todd
While the existing numeric opcodes are all limited to 4-byte bignum arguments, new opcodes will need different limits.

2014-10-17script: move CScriptID to standard.h and add a ctor for creating them from ↵Cory Fields
CScripts This allows for a reversal of the current behavior. This: CScript foo; CScriptID bar(foo.GetID()); Becomes: CScript foo; CScriptID bar(foo); This way, CScript is no longer dependent on CScriptID or Hash();
