* Remove template matching and pseudo opcodesPieter Wuille2018-05-291-7/+0
| | | | | | | | | | | | | The current code contains a rather complex script template matching engine, which is only used for 3 particular script types (P2PK, P2PKH, multisig). The first two of these are trivial to match for otherwise, and a specialized matcher for multisig is both more compact and more efficient than a generic one. The goal is being more flexible, so that for example larger standard multisigs inside SegWit outputs are more easy to implement. As a side-effect, it also gets rid of the pseudo opcodes hack.

* Support serialization as another type without castingPieter Wuille2018-03-201-1/+1
| | | | | | | | | This adds a READWRITEAS(type, obj) macro which serializes obj as if it were casted to (const type&) when const, and to (type&) when non-const. This makes it usable in serialization code that uses a single implementation for both serialization and deserializing, which doesn't know the constness of the object involved.
* Merge #10498: Use static_cast instead of C-style casts for non-fundamental typesMarcoFalke2018-02-071-1/+1
|\ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 9ad6746ccd Use static_cast instead of C-style casts for non-fundamental types (practicalswift) Pull request description: A C-style cast is equivalent to try casting in the following order: 1. `const_cast(...)` 2. `static_cast(...)` 3. `const_cast(static_cast(...))` 4. `reinterpret_cast(...)` 5. `const_cast(reinterpret_cast(...))` By using `static_cast<T>(...)` explicitly we avoid the possibility of an unintentional and dangerous `reinterpret_cast`. Furthermore `static_cast<T>(...)` allows for easier grepping of casts. For a more thorough discussion, see ["ES.49: If you must use a cast, use a named cast"](https://isocpp.github.io/CppCoreGuidelines/CppCoreGuidelines#es49-if-you-must-use-a-cast-use-a-named-cast) in the C++ Core Guidelines (Stroustrup & Sutter).

* 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.

* 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!)
