* Specify that the conflict is a spend conflict
Make the situation clearer, because there are other types of conflict.
Co-authored-by: teor <teor@riseup.net>
* Clarify that the outpoints are from inputs
Because otherwise it could lead to confusion because it could also mean
the outputs of the transaction represented as `OutPoint` references.

* Create `storage::tests::vectors` module
Refactor to follow the convention used for other tests.
* Add an `AtLeastOne::first_mut` method
A getter to allow changing the first element.
* Add an `AtLeastOne::push` method
Allow appending elements to the collection.
* Derive `Arbitrary` for `FieldNotPresent`
This is just to make the code that generates arbitrary anchors a bit
simpler.
* Test if conflicting transactions are rejected
Generate two transactions (either V4 or V5) and insert a conflicting
spend, which can be either a transparent UTXO, or a nullifier for one of
the shielded pools. Check that any attempt to insert both transactions
causes one to be accepted and the other to be rejected.

* Fix an incorrect assertion when the block locator is at the tip
This might have been triggered by receiving block hash gossips
from the new Zebra code.
* Add missing tests for zebra-state requests and responses
Specifically:
* `BlockLocator` (populated state only)
* `FindBlockHashes`
* `FindBlockHeaders`
* Test `FindBlock*` before and after the current block
* Add a specific test for bug #2789
* Refactor collect_best_chain_hashes to avoid manual index calculations

* Use `TipAction::Reset` for initialization and out-of-order blocks
Needs tests for:
- cloning a `ChainTipChange` resets the cloned instance
- skipped updates reset the cloned instance
- changing forks resets the cloned instance
* Use `TipAction::Reset` for network upgrade activation blocks
* Use an `if` expression

* Rename ChainTipReceiver to CurrentChainTip
`fastmod ChainTipReceiver CurrentChainTip zebra*`
* Update chain tip documentation and variable names
* Basic chain tip change implementation, without resets
Also includes the following name changes:
```
fastmod CurrentChainTip LatestChainTip zebra*
fastmod chain_tip_receiver latest_chain_tip zebra*
```
* Clarify the difference between `LatestChainTip` and `ChainTipChange`
* Store precalculated transactions in an `Arc`
Transaction `Hash`es are 32 bytes,
and the minimun transparent transaction size is 54 bytes.
So a full 2MB block can create 1.1MB of transaction hashes.
We use an `Arc` to avoid repeatedly cloning that much data.
* Remove the unused `Block` from `ChainTipBlock`
This drops the block as soon as it isn't needed any more.
Previously, it would stick around until every `ChainTipReceiver`
dropped their `ChainTipBlock`, even if they didn't use the `Block`
at all.
* Re-use finalized blocks for chain tip updates
This avoids serializing and deserializing blocks from the finalized state.
* Optimise tip sender equality checks
* Re-use precalculated block hashes and heights for chain tip updates
* Add chain tip mined transaction IDs
* Doc comment typo

* Always prefer the non-finalized tip in ChainTipSender
This significantly simplifies the internal implementation of ChainTipSender.
Also make the methods and types a bit more generic.
* Update ChainTipSender with blocks, not heights
Also fix a bug where queued non-finalized blocks would clear the chain tip.
* Provide a best tip hash in ChainTip receivers
* Skip finalized blocks once the non-finalized state is active
* Add tip hash and NoChainTip tests
* Remove a redundant finalized tip update
* Skip `None` updates to the finalized tip
The finalized and non-finalized tips never update to `None`
once they have added at least one block.
* Stop committing finalized queued blocks if there is an error
Also return the highest committed queued block.

* Rename BestTipHeight so it can be generalised to ChainTipSender
`fastmod BestTipHeight ChainTipSender zebra*`
For senders:
`fastmod best_tip_height chain_tip_sender zebra*`
For receivers:
`fastmod best_tip_height chain_tip_receiver zebra*`
* Rename best_tip_height module to chain_tip
* Wrap the chain tip watch channel in a ChainTipReceiver type
* Create a ChainTip trait to avoid tricky crate dependencies
And add convenience impls for optional and empty chain tips.
* Use the ChainTip trait in zebra-network
* Replace `Option<ChainTip>` with `NoChainTip`

* add value balances to non finalized state
* fix 2 tests
* fix remaining constrain issues in tests
* extend value pool test to non finalized
* WIP: fix tests after adding value pools to non-finalized state (#2647)
* Update Chain::eq_internal_state with Chain.value_balance
Also increase the number of cases in its tests,
because they didn't detect this bug.
* Calculate the chain value pool change before `Chain::push`
Code
- store the chain value pool change in `ContextuallyValidBlock`
- convert `PreparedBlock` to `ContextuallyValidBlock` using `with_block_and_spent_utxos`
(rather than `from` or `into`)
- replace `block_utxos` with `new_outputs` in `PreparedBlock`
- replace `block_utxos` with `chain_value_pool_change` in `ContextuallyValidBlock`
Tests
- create test methods for `PreparedBlock` and `ContextuallyValidBlock`
- use `test_with_zero_chain_pool_change` or `test_with_zero_spent_utxos`
to make tests pass
* fix conflicts
* build `set_current_value_pool()` only for tests
* remove redundant cfgs
* change cfg of set_current_value_pool()
* Clarify some chain field documentation
* Fix bugs in the non-finalized chain value pool calculations
1. Only revert the chain value pool balances when the tip is popped.
Don't modify them when the root is finalized.
2. Only update or revert the chain value pool balances once per block.
(Previously, the block changes were multiplied by the number of *transactions*.)
And make corresponding changes to method names and documentation.
* Add extra proptests to try to identify value balance failures
* Simplify some transaction generation code
* Add extra debugging info to value balance errors
* Actually update non-finalized chain value pools in `UpdateWith`
Previously, we were dropping the updated value pools in the `Ok` result.
So the initial (finalized) chain value pool balances were never modified.
* Rename and document value balance add methods
The names and documentation of these methods were confusing.
* Create genesis-based proptests that check chain value pools
* Increase coverage for some test vectors
* Test each chain value balance calculation for blocks 0-10
* Make continuous blockchain test errors easier to debug
* Test the exact transparent pool values for the first few blocks

* 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

This improves proptest results in CI and locally.
Proptests should be faster, because they are not discarding 1/16 results.
Failures should be minimised more often, improving failure logs,
and generating proptest seeds locally and in CI.

* Add 1 to 3 transactions to generated blocks, rather than always 2
This change improves test coverage.
As a side-effect, it reduces the average number of generated
transactions, which should improve performance.
* Add 1 to max_size generated transparent inputs, rather than always max_size
Co-authored-by: Deirdre Connolly <deirdre@zfnd.org>
* Return an error if genesis transparent coinbase data is invalid
This error prevents cryptic errors during genesis coinbase deserialization.
And fix and improve documentation.
* Use the fixed Zcash constant for generated genesis coinbase data
This change is required, because genesis transactions do not have a
coinbase height in their coinbase data.
* Add Orchard support to HistoryTree
