6. add(test): add more tests for height and transaction location serialization (#3879)
* 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

feat(consensus): Validate ZIP-212 grace period blocks using checkpoints (#3889)
* Test if mandatory checkpoint is after grace period

Check that the mandatory checkpoint height is after the ZIP-212 grace
period for both mainnet and testnet, because Zebra is currently unable
to fully validate the blocks during that grace period.

* Update mandatory checkpoint height

Require it to be after the ZIP-212 grace period so that the blocks
during the grace period are validated by the checkpoints because Zebra
can't currently fully validate blocks during that period.

* Use a `SerializedBlock` type to help serializing blocks (#3725)

* Create a `SerializedBlock` helper type

Create a type that can be used as a byte slice, but is guaranteed to
represent a valid block.

* Use `into_iter` instead of `iter`

There's no need to borrow the elements, they can be moved out directly.
This will be necessary because `&Arc<T>` doesn't implement `Borrow<T>`,
so a `SerializedBlock` can't be built directly from an `&Arc<Block>`.

* Use `SerializedBlock` in `GetBlock`

Make the type stricter to avoid storing possibly invalid values. The
bytes are still serialized as a hexadecimal string, through the usage of
`hex`.

The `serde::Deserialize` can't be derived because `hex` requires the
type to also implement `FromHex`.

Refactor `SentTransactionHash` to be a stricter type (#3706)
* Stub `sendrawtransaction` RPC method

Register the RPC method, and stub an implementation that currently just
panics. The method has a single `String` parameter with the hexadecimal
string of the raw transaction's bytes and returns a
`SentTransactionHash` wrapper type that's just a hexadecimal `String` of
the sent transaction's hash.

* Add mempool service instance to `RpcImpl`

Use a type parameter to represent the mempool service using the
interface defined by `zebra-node-services`.

* Update test vector to use a mock mempool service

Update the test to be compatible with the changes to `RpcImpl`. The mock
mempool service is expected to not be used during the test.

* Use a `tower::Buffer` for the mempool service

Make it simpler to send requests to the service in a concurrent manner.

* Return a `Future` from `send_raw_transaction`

Make the call asynchronous.

* Implement `sendrawtransaction` RPC

Deserialize the transaction and send it to be queued for verification
and subsequent inclusion in the mempool.

* Test if mempool receives sent raw transaction

Use a mock service as the mempool service and check that it receives a
sent raw transaction.

* Test using non-hexadecimal string parameter

The method should return an error.

* Test with bytes that fail deserialization

Check that the method returns an invalid parameters error if the input
can't be deserialized as a `Transaction`.

* Test if mempool errors are forwarded to caller

Mempool service errors should be sent back to the remote caller as
server errors.

* Test transactions rejected by the mempool service

Transactions that are rejected by the mempool service should result in
a server error being sent to the caller.

* Improve error message

Add the word "structurally" to make it clear that the issue is in the
transaction's deserialization.

Co-authored-by: Deirdre Connolly <durumcrustulum@gmail.com>

* Add note regarding missing `allowhighfees` param.

The parameter isn't supported yet because `lightwalletd` doesn't use it.

* Update the documentation to be consistent

Follow the convention adopted by the `get_info` RPC method.

* Implement `ToHex` and `FromHex` for `Hash`

Make it easier to generate hexadecimal strings from `transaction::Hash`
instances.

* Use `ToHex` in `Debug` and `Display`

Reduce repeated code.

* Refactor to add `bytes_in_display_order` method

Use it to remove repeated code and improve clarity a bit.

* Use `hex::serialize` to serialize transaction hash

Make the type stricter in its contents, while still serializing the
transaction has as a hexadecimal string.

* Simplify serialization attribute

Deserialization should also use `hex::deserialize`, so using the shorter
attribute makes things easier to read and more future proof.

* Update zebra-chain/src/transaction/hash.rs

* Remove unnecessary lifetime

The anonymous lifetime is automatically inferred by the compiler.

* fix(zebrad/test): stop excessive logging which causes test hangs

Estimate network chain tip height based on local node time and current best tip (#3492)
* Remove redundant documentation

The documentation was exactly the same as the documentation from the
trait.

* Calculate a mock time block delta for tests

Simulate a block being added to the chain with a random block time based
on the previous block time and the target spacing time.

* Add a `time` field to `ChainTipBlock`

Store the block time so that it's ready for a future chain that allows
obtaining the chain tip's block time.

* Add `ChainTip::best_tip_block_time` method

Allow obtaining the bes chain tip's block time.

* Add method to obtain both height and block time

Prevent any data races by returning both values so that they refer to
the same chain tip.

* Add `NetworkUpgrade::all_target_spacings` method

Returns all the target spacings defined for a network.

* Create a `NetworkChainTipEstimator` helper type

Isolate the code to calculate the height estimation in a new type, so
that it's easier to understand and doesn't decrease the readability of
the `chain_tip.rs` file.

* Add `ChainTip::estimate_network_chain_tip_height`

This is more of an extension method than a trait method. It uses the
`NetworkChainTipHeightEstimator` to actually perform the estimation, but
obtains the initial information from the current best chain tip.

* Fix typo in documentation

There was an extra closing bracket in the summary line.

* Refactor `MockChainTipSender` into a separate type

Prepare to allow mocking the block time of the best tip as well as the
block height.

* Allow sending mock best tip block times

Add a separate `watch` channel to send the best tip block times from a
`MockChainTipSender` to a `MockChainTip`.

The `best_tip_height_and_block_time` implementation will only return a
value if there's a height and a block time value for the best tip.

* Fix off-by-one height estimation error

Use Euclidean division to force the division result to round down
instead of rounding towards zero. This fixes an off-by-one error when
estimating a height that is lower than the current height, because the
fractionary result was being discarded, and it should have forced the
height to go one block back.

* Fix panics on local times very far in the past

Detect situations that might cause the block height estimate to
underflow, and return the genesis height instead.

* Fix another off-by-one height estimation error

The implementation of `chrono::Duration::num_seconds` adds one to the
number of seconds if it's negative. This breaks the division
calculation, so it has to be compensated for.

* Test network chain tip height estimation

Generate pairs of block heights and check that it's possible to estimate
the larger height from the smaller height and a displaced time
difference.

Add some proptests for lock time validation (#3089)
* Create a strategy for block heights after Sapling

Provides an arbitrary network (mainnet or testnet) and a block height
between the Sapling activation height on that network and the maximum
block height.

* Create a helper function to select block heights

Allows generating block heights inside a range using a scale factor
between 0 and 1.

* Allow specifying the outpoint index for mock UTXOs

Avoid creating multiple transparent transfers in the same transaction
with the same source UTXO, which would lead to a double spend.

* Create helper function to mock multiple transfers

Given relative block height scale factors, create a mock transparent
transfer for each one of them.

Also add a constant that serves as a guideline for the maximum number of
transparent transfers to mock.

* Create helper function to sanitize tx. version

Make sure the arbitrary transaction version is valid for the network
(testnet or mainnet) at the specified block height.

* Create `mock_transparent_transaction` helper func.

Creates a V4 or V5 mock transaction that only includes transparent
inputs and outputs.

* Create helper function for transaction validation

Performs the actual tested action of verifying a transaction. It sets up
the verifier and uses it to obtain the verification result.

* Test if zero lock time means unlocked

Generate arbitrary transactions with zero lock time, and check that they
are accepted by the transaction verifier.

* Allow changing the sequence number of an input

Add a setter method for a `transparent::Input`'s sequence number. This
setter is only available for testing.

* Test if sequence numbers can disable lock time

Create arbitrary transactions and set the sequence numbers of all of its
inputs to `u32::MAX` to see if that disables the lock time and the
transactions are accepted by the verifier.

* Test block height lock times

Make sure that the transaction verifier rejects transactions that are
still locked at a certain block height.

* Test block time lock times

Test that the transaction verifier rejects a transaction that is
validated at a block time that's before the transaction's lock time.

* Test unlocking by block height

Test that transactions unlocked at an earlier block height are accepted
by the transaction verifier.

* Test transactions unlocked by the block time

Test that transactions that were unlocked at a previous block time are
accepted by the transaction verifier.

* Fix an incorrect method comment

Fix task handling bugs, so peers are more likely to be available (#3191)
* Tweak crawler timings so peers are more likely to be available

* Tweak min peer connection interval so we try all peers

* Let other tasks run between fanouts, so we're more likely to choose different peers

* Let other tasks run between retries, so we're more likely to choose different peers

* Let other tasks run after peer crawler DemandDrop

This makes it more likely that peers will become ready.
