| | | | | | Removes conditional dependency of `src/test` on wallet. Makes multisig and P2SH tests complete without wallet built-in.

* Code style fix.BtcDrak2016-02-161-1/+2
| | | | | This if statement is a little obtuse and using braces here improves readability.
* Separate CheckLockTime() and CheckSequence() logicBtcDrak2016-02-141-20/+26
| | | | For the sake of a little repetition, make code more readable.
* BIP112: Implement CHECKSEQUENCEVERIFYMark Friedenbach2016-02-144-8/+106
| | | | | | | | | | - 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.

* | script: Remove magic numbersDavid Hill2015-10-153-5/+12
|/ | | | | This adds two new constants, MAX_OPS_PER_SCRIPT and MAX_PUBKEYS_PER_MULTISIG.
* Accept any sequence of PUSHDATAs in OP_RETURN outputsPeter Todd2015-10-014-14/+12
| | | | | | | | | | | | 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!)
* Add IsPushOnly(const_iterator pc)Peter Todd2015-10-012-2/+7
| | | | | Allows IsPushOnly() to be applied to just part of the script for OP_RETURN outputs.
* Make TX_SCRIPTHASH clear vSolutionsRet firstPeter Todd2015-10-011-0/+2
| | | | | | | 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.
