* Increment MIT Licence copyright header year on files modified in 2016isle29832016-12-311-1/+1
| | | | | | Edited via: $ contrib/devtools/copyright_header.py update .
* Make CScript (and prevector) c++11 movable.Pieter Wuille2016-12-211-1/+0
| | | | | Such moves are used when reallocating vectors that contain them, for example.

* Merge #7907: Optimize and Cleanup CScript::FindAndDeleteWladimir J. van der Laan2016-05-051-3/+12

| * Improve worst-case behavior of CScript::FindAndDeletePatrick Strateman2016-04-211-2/+11
| | | | | | | | Thanks to Sergio Lerner for identifying this issue and suggesting this kind of solution.

| * Replace memcmp with std::equal in CScript::FindAndDeletePatrick Strateman2016-04-191-1/+1
| | | | | | | | Function is stl; std::equal just makes more sense.

* BIP112: Implement CHECKSEQUENCEVERIFYMark Friedenbach2016-02-141-0/+12
| | | | | | | | | | - 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 Hill2015-10-151-1/+8
| | | | | This adds two new constants, MAX_OPS_PER_SCRIPT and MAX_PUBKEYS_PER_MULTISIG.
* Accept any sequence of PUSHDATAs in OP_RETURN outputsPeter Todd2015-10-011-1/+0
| | | | | | | | | | | | 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 Todd2015-10-011-0/+1
| | | | | Allows IsPushOnly() to be applied to just part of the script for OP_RETURN outputs.
* Resolve issue 3166.mruddy2015-07-301-1/+0
| | | | | 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.

| * Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65)Peter Todd2015-06-211-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | <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.
| * Move LOCKTIME_THRESHOLD to src/script/script.hPeter Todd2015-05-091-0/+4
| | | | | | | | Will now be needed by CHECKLOCKTIMEVERIFY code.
| * Make CScriptNum() take nMaxNumSize as an argumentPeter Todd2015-05-091-3/+4
| | | | | | | | | | While the existing numeric opcodes are all limited to 4-byte bignum arguments, new opcodes will need different limits.
