* Make address index types consistent
* Simplify non-finalized address index updates
* Update snapshots for address index queries
* Simplify non-finalized UTXO query
* Add a query method for non-finalized address balance changes
* Add a query method for finalized state address balances
* Add a query function for address balances
* Refactor balance queries to make them repeatable
* Retry interrupted finalized balance queries
* Pop chain root blocks until it matches the finalized tip
* Avoid cloning the chain
It has already been cloned by the watch receiver
* Refactor and fix documentation of the balance query code
* Add round-trip test for OutputLocation disk serialization
* Make the transaction snapshot tests more accurate
Previously, we were showing the genesis transaction hash at height 0, index 0.
But its hash is actually not stored by location in the database,
because the genesis transaction is skipped due to a consensus rule.
* Update the transaction snapshot data
* Add history tree snapshot tests
At the current test heights, the history trees are all empty.
* Add the history tree snapshot data
* Update comments
* Simplify snapshot test code
* Make some serde::Serialize impls test-only, so we can hex-encode them
This should also speed up release compilation a bit.
* Add snapshot test code for UTXOs
* Add snapshot data for UTXOs
* Make Amount arithmetic more generic
To modify generated amounts, we need some extra operations on `Amount`.
We also need to extend existing operations to both `NonNegative` and
`NegativeAllowed` amounts.
* Add a constrain method for ValueBalance
* Derive Eq for ValueBalance
* impl Neg for ValueBalance
* Make some Amount arithmetic expectations explicit
* Explain why we use i128 for multiplication
And expand the overflow error details.
* Expand Amount::sum error details
* Make amount::Error field order consistent
* Rename an amount::Error variant to Constraint, so it's clearer
* Add specific pool variants to ValueBalanceError
* Update coinbase remaining value consensus rule comment
This consensus rule was updated recently to include coinbase transactions,
but Zebra doesn't check block subsidy or miner fees yet.
* Add test methods for modifying transparent values and shielded value balances
* Temporarily set values and value balances to zero in proptests
In both generated chains and proptests that construct their own transactions.
Using zero values reduces value calculation and value check test coverage.
A future change will use non-zero values, and fix them so the check passes.
* Add extra fields to remaining transaction value errors
* Swap the transparent value balance sign to match shielded value balances
This makes the signs of all the chain value pools consistent.
* Use a NonNegative constraint for transparent values
This fix:
* makes the type signature match the consensus rules
* avoids having to write code to handle negative values
* Allocate total generated transaction input value to outputs
If there isn't enough input value for an output, set it to zero.
Temporarily reduce all generated values to avoid overflow.
(We'll remove this workaround when we calculate chain value balances.)
* Consistently use ValueBalanceError for ValueBalances
* Make the value balance signs match the spec
And rename and document methods so their signs are clearer.
* Convert amount::Errors to specific pool ValueBalanceErrors
* Move some error changes to the next PR
* Add extra info to remaining transaction value errors (#2585)
* Distinguish between overflow and negative remaining transaction value errors
And make some error types cloneable.
* Add methods for updating chain value pools (#2586)
* Move amount::test to amount::tests:vectors
* Make ValueBalance traits more consistent with Amount
- implement Add and Sub variants with Result and Assign
- derive Hash
* Clarify some comments and expects
* Create ValueBalance update methods for blocks and transactions

* implement Sum for Amount
* check overflows
* add a `zero()` method to `Amount`
* impl iter::Sum<&Amount<C>> for Result<Amount<C>>
And modify the tests so they test both reference and value based sums.
* use `try_fold()`

* Add the constraint name to the Amount debug format
* Test consensus-critical serialization for Amount
Previously we were testing `serde` and `bincode` serialization,
which uses a completely different code path.
Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com>
* Implement `PartialEq<i64>` for `Amount`
Allows to compare an `Amount` instance directly to an integer.
* Add `SerializationError::BadTransactionBalance`
Error variant representing deserialization of a transaction that doesn't
conform to the Sapling consensus rule where the balance MUST be zero if
there aren't any shielded spends and outputs.
* Validate consensus rule when deserializing
Return an error if the deserialized V4 transaction has a non-zero value
balance but doesn't have any Sapling shielded spends nor outputs.
* Add consensus rule link to field documentation
Describe how the consensus rule is validated structurally by
`ShieldedData`.
* Clarify that `value_balance` is zero
Make the description more concise and objective.
Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com>
* Update field documentation
Include information about how the consensus rule is guaranteed during
serialization.
Co-authored-by: teor <teor@riseup.net>
* Remove `check::sapling_balances_match` function
The check is redundant because the respective consensus rule is
validated structurally by `ShieldedData`.
* Test deserialization of invalid V4 transaction
A transaction with no Sapling shielded spends and no outputs but with a
non-zero balance value should fail to deserialize.
* Change least-significant byte of the value balance
State how the byte index is calculated, and change the least
significant-byte to be non-zero.

* add general and founders reward subsidy modules
* validate founders reward
* Use funding streams after Canopy on testnet
ZIP-1014 only applies to mainnet, where Canopy is at the first halving.
On testnet, Canopy is before the first halving, and the dev fund rules
apply from Canopy. (See ZIP-214.)
