* Ensure `-maxsigcachesize` is in valid rangeJohn Newbery2017-02-172-2/+5
| | | | | | | - If the -maxsigcachesize parameter is set to zero, setup a minimum sized sigcache (2 elements) rather than segfaulting. - Handle maxsigcachesize being negative - Handle maxsigcachesize being too large

* | Get rid of nType and nVersionPieter Wuille2016-11-072-16/+18
| | | | | | | | | | | | | | | | | | | | | | Remove the nType and nVersion as parameters to all serialization methods and functions. There is only one place where it's read and has an impact (in CAddress), and even there it does not impact any of the recursively invoked serializers. Instead, the few places that need nType or nVersion are changed to read it directly from the stream object, through GetType() and GetVersion() methods which are added to all stream classes.
* | Make GetSerializeSize a wrapper on top of CSizeComputerPieter Wuille2016-11-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | Given that in default GetSerializeSize implementations created by ADD_SERIALIZE_METHODS we're already using CSizeComputer(), get rid of the specialized GetSerializeSize methods everywhere, and just use CSizeComputer. This removes a lot of code which isn't actually used anywhere. For CCompactSize and CVarInt this actually removes a more efficient size computing algorithm, which is brought back in a later commit.
* | Make streams' read and write return voidPieter Wuille2016-11-071-2/+1
| | | | | | | | | | | | | | | | The stream implementations had two cascading layers (the upper one with operator<< and operator>>, and a lower one with read and write). The lower layer's functions are never cascaded (nor should they, as they should only be used from the higher layer), so make them return void instead.
* | libconsensus: Add input validation of flagsWladimir J. van der Laan2016-10-202-0/+13
|/ | | | | | | | | | | | | Makes it an error to use flags that have not been defined on the libconsensus API. There has been some confusion as to what pass to libconsensus, and (combined with mention in the release notes) this should clear it up. Using undocumented flags is a risk because their meaning, and what combinations are allowed, changes from release to release. E.g. it is no longer possible to pass (CLEANSTACK | P2SH) without running into an assertion after the segwit changes.

* 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.
