Also, remove scope of txnouttype in fuzz tests temporarily. The next commit will add scopes to all txnouttype.
2020-06-19Disallow automatic conversion between hash typesBen Woosley
A templated BaseHash does not allow for automatic conversion, thus conversions much be explicitly allowed / whitelisted, which will reduce the risk of unintended conversions.
2020-06-19Explicitly support conversion between equivalent hash typesBen Woosley
ScriptHash <-> CScriptID CKeyID -> PKHash PKHash -> WitnessV0KeyHash
2020-06-19Use explicit conversion from WitnessV0KeyHash -> CKeyIDBen Woosley
These types are equivalent, in data etc, so they need only their data cast across.
2020-06-19Use explicit conversion from PKHash -> CKeyIDBen Woosley
These types are equivalent, in data etc, so they need only their data cast across. Note a function is used rather than a casting operator as CKeyID is defined at a lower level than script/standard
2020-06-19Convert CPubKey to WitnessV0KeyHash directlyBen Woosley
The round-tripping through PKHash has no effect, and is potentially misleading as such.
2020-06-19Prefer explicit CScriptID constructionBen Woosley

c57f03ce1741b38af448bec7b22ab9f8ac21f067 refactor: Replace const char* to std::string (Calvin Kim) Pull request description: Rationale: Addresses #19000 Some functions should be returning std::string instead of const char*. This commit changes that. Main benefits/reasoning: 1. The functions never return nullptr, so returning a string makes code at call sites easier to review (reviewers don't have to read the source code to verify that a nullptr is never returned) 2. All call sites convert to string anyway ACKs for top commit: MarcoFalke: re-ACK c57f03ce17 (no changes since previous review) 🚃 Empact: Fair enough, Code Review ACK https://github.com/bitcoin/bitcoin/pull/19004/commits/c57f03ce1741b38af448bec7b22ab9f8ac21f067 practicalswift: ACK c57f03ce1741b38af448bec7b22ab9f8ac21f067 -- patch looks correct hebasto: re-ACK c57f03ce1741b38af448bec7b22ab9f8ac21f067 Tree-SHA512: 9ce99bb38fe399b54844315048204cafce0f27fd8f24cae357fa7ac6f5d8094d57bbf5f5c1f5878a65f2d35e4a3f95d527eb17f49250b690c591c0df86ca84fd

Tests are only failing in 0.19 branch, likely because that release still uses p2sh-segwit addresses rather than bech32 by default. I'll devise a test case to catch this going forward.

Two new configuration options are added: * `-addresstype`, with options `legacy`, `p2sh`, and `bech32`. It controls what kind of addresses are produced by `getnewaddress`, `getaccountaddress`, and `createmultisigaddress`. * `-changetype`, with the same options, and by default equal to `-addresstype`, that controls what kind of change is used. All wallet private and public keys can be used for any type of address. Support for address types dependent on different derivation paths will need a major overhaul of how our internal detection of outputs work. I expect that that will happen for a next major version. The above also applies to imported keys, as having a distinction there but not for normal operations is a disaster for testing, and probably for comprehension of users. This has some ugly effects, like needing to associate the provided label to `importprivkey` with each style address for the corresponding key. To deal with witness outputs requiring a corresponding redeemscript in wallet, three approaches are used: * All SegWit addresses created through `getnewaddress` or multisig RPCs explicitly get their redeemscripts added to the wallet file. This means that downgrading after creating a witness address will work, as long as the wallet file is up to date. * All SegWit keys in the wallet get an _implicit_ redeemscript added, without it being written to the file. This means recovery of an old backup will work, as long as you use new software. * All keypool keys that are seen used in transactions explicitly get their redeemscripts added to the wallet files. This means that downgrading after recovering from a backup that includes a witness address will work. These approaches correspond to solutions 3a, 1a, and 5a respectively from https://gist.github.com/sipa/125cfa1615946d0c3f3eec2ad7f250a2. As argued there, there is no full solution for dealing with the case where you both downgrade and restore a backup, so that's also not implemented. `dumpwallet`, `importwallet`, `importmulti`, `signmessage` and `verifymessage` don't work with SegWit addresses yet. They're remaining TODOs, for this PR or a follow-up. Because of that, several tests unexpectedly run with `-addresstype=legacy` for now.

2015-10-01Accept any sequence of PUSHDATAs in OP_RETURN outputsPeter Todd
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!)

Transactions that fail CLTV verification will be rejected from the mempool, making it easy to test the feature. However blocks containing "invalid" CLTV-using transactions will still be accepted; this is *not* the soft-fork required to actually enable CLTV for production use.
