* Add history trees for each height in non-fin state
* Refactor formatting
* Pass the treestate to the finalized state
I created a new structure `FinalizedBlockWithTrees` that wraps the
treestate and the finalized block. I did that because the original
`FinalizedBlock` is `Eq`, but `HistoryTree` can't be `Eq`.
This makes Zebra faster because:
1. The finalized state doesn't retrieve the treestate from the disk if
the non-finalized state supplies it.
2.The finalized state doesn't recompute the treestate if the
non-finalized state supplies it.
* Check block commitment before updating hist tree
* Store Sprout commitment trees in non-fin state
* Send trees for the root block to fin-state
When committing a block and sending the treestate from the non-finalized
state to the finalized state, Zebra was sending trees that correspond to
the tip block instead of trees that correspond to the root block of the
best chain. This commit fixes that.

* Export the `zebra_state::Config::db_path` method
Make it easier for tests to discover the sub-directory used to store
the chain state data.
* Generate code for interfacing with lightwalletd
Use the `tonic-build` crate to generate Rust code for communicating with
lightwalletd using gRPC.
The `*.proto` files were obtained from the Zcash lightwalletd
repository.
* Use `block::Height` instead of `Height`
Import the `block` instead to make it slightly clearer.
* Add helper function to remove a file if it exists
Try to remove it and ignore an error if it says that the file doesn't
exist. This will be used later to remove the lock file from a copied
chain state directory.
* Add helper function to copy chain state dirs
Copy an existing chain state directory into a new temporary directory.
* Add a `BoxStateService` type alias
Make it easier to write and read a boxed version of a state service.
* Add a helper function to start the state service
Make it easier to specify the state service to use an existing state
cache directory.
* Import `eyre!` macro at the module level
Allow it to be used in different places without having to repeat the
imports.
* Add `load_tip_height_from_state_directory` helper
A function to discover the current chain tip height stored in a state
cache.
* Add helper function to prepare partial sync. state
Loads a partially synchronized cached state directory into a temporary
directory that can be used by a zebrad instance, and also returns the
chain tip block height of that state.
* Add `perform_full_sync_starting_from` helper
Runs a zebrad with an existing partially synchronized state, and
finishes synchronizing it to the network chain tip.
* Add function to load transactions from a block
Use a provided state service to load all transactions from a block at a
specified height.
The state service is a generic type parameter, because
`zebra_state::service::ReadStateService` is not exported publicly. Using
a generic type parameter also allows the service to be wrapped in layers
if needed in the future.
* Add `load_transactions_from_block_after` helper
A function to load transactions from a block stored in a cached state
directory. The cached state must be synchronized to a chain tip higher
than the requested height.
* Add helper function to load some test transactions
Given a partially synchronized chain state, it will extend that chain by
performing a full synchronization, and obtain some transactions from one
of the newly added blocks.
* Update `spawn_zebrad_for_rpc_without_initial_peers`
Wait until the mempool is activated.
* Add method to start lightwalletd with RPC server
Returns the lightwalletd instance and the port that it's listening for
RPC connections.
The instance can reuse an existing cached lightwalletd state if the
`LIGHTWALLETD_DATA_DIR` environment variable is set.
* Add a `LightwalletdRpcClient` type alias
To make it easier to identify the type generated from the Protobuf
files.
* Add helper function to connect to lightwalletd
Prepare an RPC client to send requests to a lightwalletd instance.
* Add a `prepare_send_transaction_request` helper
Creates a request message for lightwalletd to send a transaction.
* Add test to send transactions using lightwalletd
Obtain some valid transactions from future blocks and try to send them
to a lightwalletd instance connected to a zebrad instance that hasn't
seen those transactions yet. The transactions should be successfully
queued in Zebra's mempool.
* Make `zebra_directory` parameter generic
Allow using a `TempDir` or a `PathBuf`.
* Move lightwalletd protobuf files
Place them closer to the module directory, so that it's clearer that
they specify the RPC protocol for lightwalletd, and not Zebra itself.
* Don't use coinbase transactions in the test
Coinbase transactions are rejected by the mempool.
* Don't remove state lock file
It is removed automatically by Zebra when it shuts down, so if it exists
it should be reported as a bug.
* Force mempool to be enabled in Zebrad instance
Speed up the initialization of the Zebrad instance used for lightwalletd
to connect to.
* Refactor to create `LIGHTWALLETD_DATA_DIR_VAR`
Document how the environment variable can be used to speed up the test.
* Check for process errors in spawned Zebra instance
Enable checking for known process failure messages.
* Add `FINISH_PARTIAL_SYNC_TIMEOUT` constant
Document why it exists and how the choice of the value affects the test.
* Add `LIGHTWALLETD_TEST_TIMEOUT` constant
And use it for the Zebrad and the Lightwalletd instances used in the
send transaction integration test.
* Check `lightwalletd` process for errors
Enable checking the lightwalletd process for known failure messages.
* Update `tonic` and `prost` dependencies
Use the latest version and fix CI failures because `rustfmt` isn't
installed in the build environment.
* Create `send_transaction_test` module
Move the send transaction using lightwalletd test and its helper
functions into a new module.
* Move `LIGHTWALLETD_TEST_TIMEOUT` constant
Place it in the parent `lightwalletd` module.
* Move gRPC helper functions and types to `rpc` mod.
Make them more accessible so that they can be used by other tests.
* Create a `cached_state` module
Move the test utility functions related to using a cached Zebra state
into the module.
* Move `perform_full_sync_starting_from` to `sync`
Keep to closer to the synchronization utility functions.
* Move Zebra cached state path variable constant
Place it in the `cached_state` module.
* Skip test if `ZEBRA_TEST_LIGHTWALLETD` is not set
Make it part of the set of tests ignored as a whole if no lightwalletd
tests should be executed.
* Move `spawn_zebrad_for_rpc_without_initial_peers`
Place it in the `launch` sub-module.
* Rename `rpc` module into `wallet_grpc`
Avoid any potential misunderstandings when the name is seen out of
context.
* Allow duplicate `heck` dependency
At least until `structopt` is updated or `zebra-utils` is updated to use
`clap` 3.
* Fix a deny.toml typo
* fix(build): CMake is required by `prost` crate

* Refactor instrumented records in `ChainTipSender`
Record the fields using a helper method. This reduces duplicate code and
prepares for removing the `active_value` field from the type, because
the replacement for it has to be atomically read to avoid a deadlock
when reading from the `watch::Sender` endpoint.
* Replace `active_value` field with sender borrow
Now that Tokio has been updated to a version in which `watch::Sender`
has a `borrow` method, we can remove the `active_value` field.
To prevent a deadlock like the one that happened with the synchronizer
some time ago, the method instrumentation was slightly refactored to
have the fields recorded in helper methods that avoid obtaining a
read-lock twice.
* Remove some `TODO` comments
They are resolved with the current changes.
* Refactor to avoid obtaining current `Span` twice
This is a minor optimization to remove an unnecessary second call to
`tracing::Span::current()`.
* Add a comment about preventing dead-locks
Explain why a binding can't be created for the old tip reference.
* Retry after log ssh failures in full sync test

* Fix up snapshot tests for the new height range API
* Add `Amount::serialize_as_string` helper method
A helper method that makes it easier to serialize an `Amount` as a
string. This is needed for the response type of the `getaccountbalance`
RPC.
* Implement state service call for address balance
Add `Read{Request,Response}::AddressBalance` variants and implement the
handler that calls the query function.
* Create an `AddressBalance` response type
Only contains the `balance` field which is needed by `lightwalletd`.
That field is serialized as a string, following the RPC specification.
* Implement `get_address_balance` RPC
Query the read-only state service for the information, and wrap it in an
`AddressBalance` response type so that it is serialized correctly.
* Run `rustfmt` inside `proptest!` block
Fix some minor formatting details.
* Test `get_address_balance` with valid addresses
Check that the RPC leads to a query to the mocked state service for a
balance amount.
* Test `get_address_balance` with invalid addresses
An error message should be returned by the RPC.
* Rename metric to `address_balance`
Keep it consistent with how it's named in other places.
