Function is stl; std::equal just makes more sense.
2016-04-18wallet_ismine.h → script/ismine.hWladimir J. van der Laan
Removes conditional dependency of `src/test` on wallet. Makes multisig and P2SH tests complete without wallet built-in.

2016-02-16Code style fix.BtcDrak
This if statement is a little obtuse and using braces here improves readability.
2016-02-14Separate CheckLockTime() and CheckSequence() logicBtcDrak
For the sake of a little repetition, make code more readable.
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.

Based on the earlier BIP66 soft-fork logic implemented by Pieter Wuille's 5a47811da5158df763aa2fca09ce646ee0c51e7b
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.
2015-10-01Make TX_SCRIPTHASH clear vSolutionsRet firstPeter Todd
Previously unlike other transaction types the TX_SCRIPTHASH would not clear vSolutionsRet, which means that unlike other transaction types if it was called twice in a row you would get the result of the previous invocation as well.
