The expectation is that the results returned from `testmempoolaccept` are what you'd get from test-then-submitting each transaction individually, in that order (this means the package is expected to be sorted in topological order, for now at least). The validation is also atomic: in the case of failure, it immediately halts and may return "unfinished" `MempoolAcceptResult`s for transactions that weren't fully validated. The API for 1 transaction stays the same. **Motivation:** - This allows you to test validity for transaction chains (e.g. with multiple spending paths and where you don't want to broadcast yet); closes #18480. - It's also a first step towards package validation in a minimally invasive way. - The RPC commit happens to close #21074 by clarifying the "allowed" key. There are a few added restrictions on the packages, mostly to simplify the logic for areas that aren't critical to main package use cases: - No package can have conflicts, i.e. none of them can spend the same inputs, even if it would be a valid BIP125 replacement. - The package cannot conflict with the mempool, i.e. RBF is disabled. - The total count of the package cannot exceed 25 (the default descendant count limit), and total size cannot exceed 101KvB (the default descendant size limit). If you're looking for review comments and github isn't loading them, I have a gist compiling some topics of discussion [here](https://gist.github.com/glozow/c3acaf161c95bba491fce31585b2aaf7) ACKs for top commit: laanwj: Code review re-ACK 13650fe2e527bf0cf5d977bf5f3f1563b853ecdc jnewbery: Code review ACK 13650fe2e527bf0cf5d977bf5f3f1563b853ecdc ariard: ACK 13650fe Tree-SHA512: 8c5cbfa91a6c714e1c8710bb281d5ff1c5af36741872a7c5df6b24874d6272b4a09f816cb8a4c7de33ef8e1c2a2c252c0df5105b7802f70bc6ff821ed7cc1a2f

2021-05-24[policy] limit package sizesglozow
Maximum number of transactions allowed in a package is 25, equal to the default mempool descendant limit: if a package has more transactions than this, either it would fail default mempool descendant limit or the transactions don't all have a dependency relationship (but then they shouldn't be in a package together). Same rationale for 101KvB virtual size package limit. Note that these policies are only used in test accepts so far.
2021-05-24Merge bitcoin/bitcoin#21848: refactor: Make CFeeRate constructor ↵MarcoFalke
architecture-independent fafd121026c4f1e25d498983e4f88c119516552b refactor: Make CFeeRate constructor architecture-independent (MarcoFalke) Pull request description: Currently the constructor is architecture dependent. This is confusing for several reasons: * It is impossible to create a transaction larger than the max value of `uint32_t`, so a 64-bit `size_t` is not needed * Policy (and consensus) code should be arch-independent * The current code will print spurious compile errors when compiled on 32-bit systems: ``` policy/feerate.cpp:23:22: warning: result of comparison of constant 9223372036854775807 with expression of type 'size_t' (aka 'unsigned int') is always true [-Wtautological-constant-out-of-range-compare] assert(nBytes_ <= uint64_t(std::numeric_limits<int64_t>::max())); ``` Fix all issues by making it arch-independent.

2021-05-20[policy] Define packagesglozow
Define the Package type as an alias for a vector of transactions for now. Add PackageValidationResult, similar to TxValidationResult and BlockValidationResult for package-wide errors that cannot be reported within a single transaction result, such as having too many transactions in the package. We can update the concept of what a package is and have different logic for packages vs lists of transactions in the future, e.g. for package relay.

2020-11-25Add MAX_STANDARD_SCRIPTSIG_SIZE to policysanket1729
Bitcoin core has a standardness rule for max satisfaction script sig size. This PR adds to the policy header file so that it is documented along with along policy rules. The initial reasoning that 1650 is an implicit limit(would not reached assuming all other policy rules are being followed) is outdated. As we now know, bitcoin transactions can have spend conditions are more than just signatures and there may exist p2sh transactions involving 100 byte preimages that maybe non-standard because of this rule. Because this rule is no longer implicit, we should explicitly document it in policy header file

2020-10-30Only relay Taproot spends if next block has it activePieter Wuille
2020-10-12Make Taproot spends standard + policy limitsPieter Wuille
This adds a `TxoutType::WITNESS_V1_TAPROOT` for P2TR outputs, and permits spending them in standardness rules. No corresponding `CTxDestination` is added for it, as that isn't needed until we want wallet integration. The taproot validation flags are also enabled for mempool transactions, and standardness rules are added (stack item size limit, no annexes).

2020-08-04Add txids with non-standard inputs to reject filterSuhas Daftuar
Our policy checks for non-standard inputs depend only on the non-witness portion of a transaction: we look up the scriptPubKey of the input being spent from our UTXO set (which is covered by the input txid), and the p2sh checks only rely on the scriptSig portion of the input. Consequently it's safe to add txids of transactions that fail these checks to the reject filter, as the witness is irrelevant to the failure. This is helpful for any situation where we might request the transaction again via txid (either from txid-relay peers, or if we might fetch the transaction via txid due to parent-fetching of orphans). Further, in preparation for future witness versions being deployed on the network, ensure that WITNESS_UNKNOWN transactions are rejected in AreInputsStandard(), so that transactions spending v1 (or greater) witness outputs will fall into this category of having their txid added to the reject filter.
