* 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!)

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.
