* Prevector typePieter Wuille2015-11-131-5/+9

* 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.

| | | | - use one CReserveScript per mining thread

|\ | | | | | | | | | | | | ffd75ad Enable CHECKLOCKTIMEVERIFY as a standard script verify flag (Peter Todd) bc60b2b Replace NOP2 with CHECKLOCKTIMEVERIFY (BIP65) (Peter Todd) 48e9c57 Move LOCKTIME_THRESHOLD to src/script/script.h (Peter Todd) 99088d6 Make CScriptNum() take nMaxNumSize as an argument (Peter Todd)
| * 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.

| | | | | Also use the new flag as a standard rule, and replace the IsCanonicalPush standardness check with it (as it is more complete).

| | | | This should move to a util header once their dependencies are cleaned up.
* script: move CScriptID to standard.h and add a ctor for creating them from ↵Cory Fields2014-10-171-6/+0
| | | | | | | | | | | | | | | | CScripts This allows for a reversal of the current behavior. This: CScript foo; CScriptID bar(foo.GetID()); Becomes: CScript foo; CScriptID bar(foo); This way, CScript is no longer dependent on CScriptID or Hash();
