Philip Kaufmann 27df4123c4 make all catch() arguments const
- I saw this on http://en.cppreference.com/w/cpp/language/try_catch and
  thought it would be a good idea
- also unify used format to better be able to search for exception
  uses in our codebase

Pieter Wuille b6e03cc592 Add SCRIPT_VERIFY_CLEANSTACK (BIP62 rule 6)
Based on an earlier patch by Peter Todd, though the rules here are different
(P2SH scripts should not have a CLEANSTACK check before the P2SH evaluation).

2014-11-20 15:29:28 +01:00
Pieter Wuille 98b135f97f Make STRICTENC invalid pubkeys fail the script rather than the opcode.
This turns STRICTENC turn into a softforking-safe change (even though it
is not intended as a consensus rule), and as a result guarantee that using
it for mempool validation only results in consensus-valid transactions in
the mempool.

0391423 Discourage NOPs reserved for soft-fork upgrades (Peter Todd)

Discourage NOPs reserved for soft-fork upgrades
NOP1 to NOP10 are reserved for future soft-fork upgrades. In the event
of an upgrade such NOPs have *VERIFY behavior, meaning that if their
arguments are not correct the script fails. Discouraging these NOPs by
rejecting transactions containing them from the mempool ensures that
we'll never accept transactions, nor mine blocks, with scripts that are
now invalid according to the majority of hashing power even if we're not
yet upgraded. Previously this wasn't an issue as the IsStandard() rules
didn't allow upgradable NOPs anyway, but 7f3b4e95 relaxed the
IsStandard() rules for P2SH redemptions allowing any redeemScript to be
spent.

We *do* allow upgradable NOPs in scripts so long as they are not
executed. This is harmless as there is no opportunity for the script to
be invalid post-upgrade.

Cory Fields ab9edbd6b6 script: create sane error return codes for script validation and remove logging
Attempt to codify the possible error statuses associated with script
validation. script/types.h has been created with the expectation that it will
be part of the public lib interface. The other flag enums will be moved here in
a future commit.

Logging has also been removed in order to drop the dependency on core.h. It can
be re-added to bitcoind as-needed. This makes script verification finally free
of application state and boost!

Eventually (after 0.10) these files will hold the logic for crypto
verification routines, and CKey/CPubKey will call into them.

Pieter Wuille 698c6abb25 Add SCRIPT_VERIFY_MINIMALDATA (BIP62 rules 3 and 4)
Also use the new flag as a standard rule, and replace the IsCanonicalPush
standardness check with it (as it is more complete).

Cory Fields 066e2a1403 script: move CScriptID to standard.h and add a ctor for creating them from 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();

Pieter Wuille 9df9cf5a9f Make SCRIPT_VERIFY_STRICTENC compatible with BIP62
* Delete canonical_tests.cpp, and move the tests to script_tests.cpp.
* Split off SCRIPT_VERIFY_DERSIG from SCRIPT_VERIFY_STRICTENC (the BIP62 part of it).
* Change signature STRICTENC/DERSIG semantics to fail the script entirely rather than the CHECKSIG result (softfork safety, and BIP62 requirement).
* Add many autogenerated tests for several odd cases.
* Mention specific BIP62 rules in the script verification flags.
