* fix(network): split synthetic NotFoundRegistry from message NotFoundResponse
* docs(network): Improve `notfound` message documentation
* refactor(network): Rename MustUseOneshotSender to MustUseClientResponseSender
```
fastmod MustUseOneshotSender MustUseClientResponseSender zebra*
```
* docs(network): fix a comment typo
* refactor(network): remove generics from MustUseClientResponseSender
* refactor(network): add an inventory collector to Client, but don't use it yet
* feat(network): register missing peer responses as missing inventory
We register this missing inventory based on peer responses,
or connection errors or timeouts.
Inbound message inventory tracking requires peers to send `notfound` messages.
But `zcashd` skips `notfound` for blocks, so we can't rely on peer messages.
This missing inventory tracking works regardless of peer `notfound` messages.
* refactor(network): rename ResponseStatus to InventoryResponse
```sh
fastmod ResponseStatus InventoryResponse zebra*
```
* refactor(network): rename InventoryStatus::inner() to to_inner()
* fix(network): remove a redundant runtime.enter() in a test
* doc(network): the exact time used to filter outbound peers doesn't matter
* fix(network): handle block requests slightly more efficiently
* doc(network): fix a typo
* fmt(network): `cargo fmt` after rename ResponseStatus to InventoryResponse
* doc(test): clarify some test comments
* test(network): test synthetic notfound from connection errors and peer inventory routing
* test(network): improve inbound test diagnostics
* feat(network): add a proptest-impl feature to zebra-network
* feat(network): add a test-only connect_isolated_with_inbound function
* test(network): allow a response on the isolated peer test connection
* test(network): fix failures in test synthetic notfound
* test(network): Simplify SharedPeerError test assertions
* test(network): test synthetic notfound from partially successful requests
* test(network): MissingInventoryCollector ignores local NotFoundRegistry errors
* fix(network): decrease the inventory rotation interval
This stops us waiting 3-4 sync resets (4 minutes) before we retry a missing block.
Now we wait 1-2 sync resets (2 minutes), which is still a reasonable rate limit.
This should speed up syncing near the tip, and on testnet.
* fmt(network): cargo fmt --all
* cleanup(network): remove unnecessary allow(dead_code)
* cleanup(network): stop importing the whole sync module into tests
* doc(network): clarify syncer inventory retry constraint
* doc(network): add a TODO for a fix to ensure API behaviour remains consistent

* refactor(network): rename Advertised to Available
```sh
fastmod Advertised Available zebra*
fastmod advertised available zebra*
```
* refactor(network): allow different available and missing types inside an InventoryStatus
And rename it to ResponseStatus.
Split the methods between ResponseStatus and an InventoryStatus alias.
* refactor(network): add a block_hash convenience method to InventoryHash
* test(network): improve failure logs for connection tests
* fix(inbound): move address sanitization into the response future
* feat(network): send notfound when Zebra doesn't have a block or transaction
* doc(network): move module docs to the top of each module
This makes them more likely to get updated when the module changes.
* fix(network): stop sending unsupported missing inventory types to the registry
* test(network): inbound messages are forwarded to the registry
* test(inbound): test Peers requests to the inbound service, directly and via TCP
* test(network): notfound block responses are sent by the inbound service
* test(network): notfound tx responses are sent by the inbound service
* test(network): increase sync test mock service timeout
The code that these tests use hasn't actually changed much,
and they are only failing on some platforms (coverage, macOS).
So it seems like the extra concurrent inbound tests have pushed them
past their time limit.
(Perhaps due to TCP system calls, or extra serialization work.)
* doc(network): fix typo
Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
* test(network): remove unnecessary multi-threaded runtime from tests
This prevents `MockService<zebra_state>` timeouts
in the `sync_block_too_high_extend_tips` test,

* fix(network): don't immediately rotate a new empty inventory registry
* fix(network): assert that only expected inventory variants are stored in the registry

* Refactor setup of `Connection` test vectors
Add a `new_test_connection` helper function to create a `Connection`
instance that's ready for testing.
* Check that no inbound requests are sent
Return the mock inbound service from `new_test_connection` and assert
that no requests were sent to it in any test.
* Replace `&mut Vec<u8>` with an `mpsc` channel
Make it easier to run the connection task in the background, i.e.,
remove any lifetime constraints from the borrowed buffer so that
`Connection` is `'static`.
It's now also easier to assert on individual messages sent from the
`Connection` instance.
* Make `MockServiceBuilder::finish` public
Allow test functions to be generic when creating a `MockService`, so
that caller functions actually determine if the type of `MockService`
assertions.
* Move `new_test_connection` to parent module
Make it more generic so that it can be used later in property tests as
well.
* Derive `Eq` and `PartialEq` for network `Response`
Allow intercepted `Response` instances to be easily compared in tests.
* Test block request cancel causes an error cascade
This is the scenario that caused the block synchronizer to reset every
few minutes, which made it considerably slower.
* Ignore unexpected block responses
It's likely that it's just a response for a previously cancelled block
request.
* Stop holding completed messages until the next inbound message
* Add more info to network message block download debug logs
* Simplify address metrics logs
* Try handling inbound messages as responses, then try as a new request
* Improve address book logging
* Fix a race between the first heartbeat and getaddr requests
* Temporarily reduce the getaddr fanout to 1
* Update metrics when exiting the Connection run loop
* Downgrade some debug logs to trace
* create a test for message broadcast to peers
* remove dbg comment

* Delete an unused timer future
* Make error strings in metrics less verbose
* Downgrade some error logs to info
* Remove a redundant expect
* Avoid unnecessary allocations for connection state metrics
* Fix missed updates to mempool and block gossip metrics
* Replace usage of `discover::Change` with a tuple
Remove the assumption that a `Remove` variant would never be created
with type changes that allow the compiler to guarantee that assumption.
* Add a `version` field to the `Client` type
Keep track of the peer's reported protocol version.
* Create `LoadTrackedClient` type
A `peer::Client` type wrapper that implements `Load`. This helps with
the creation of a client service that has extra peer information to be
accessed without having to send requests.
* Use `LoadTrackedClient` in `initialize`
Ensure that `PeerSet` receives `LoadTrackedClient`s so that it will be
able to query the peer's protocol version later on.
* Require `LoadTrackedClient` in `PeerSet`
Replace the generic type with a concrete `LoadTrackedClient` so that we
can query its version.
* Create `MinimumPeerVersion` helper type
A type to track the current minimum protocol version for connected
peers based on the current block height.
* Use `MinimumPeerVersion` in handshakes
Keep the code to obtain the current minimum peer protocol version in a
central place.
* Add a `MinimumPeerVersion` instance to `PeerSet`
Prepare it to be able to disconnect from outdated peers based on the
current minimum supported peer protocol version.
* Disconnect from ready services for outdated peers
When the minimum peer protocol version is detected to have changed
(because of a network upgrade), remove all ready services of peers that
became outdated.
* Cancel added unready services of outdated peers
Only add an unready service if it's for a peer that has a supported
protocol version. Otherwise, add it but drop the cancel handle so that
the `UnreadyService` can execute and detect that it was cancelled.
* Avoid adding ready services for outdated peers
If a service becomes ready but it's for a connection to an outdated
peer, drop it.
* Improve comment inside `crawl_and_dial`
Describe an edge case that is also handled but was not explicit.

* Test if calculated minimum peer version is correct
Given an arbitrary best chain tip height, check that the calculated
minimum peer protocol version is the expected value.
* Test if minimum version changes with chain tip
Apply an arbitrary list of chain tip height updates and check that for
each update the minimum peer version is calculated correctly.
* Test minimum peer version changed reports
Simulate a series of best chain tip height updates, and check for
minimum peer version updates at least once between them. Changes should
only be reported once.
* Create a `MockedClientHandle` helper type
Used to create and then track a mock `Client` instance.
* Add `MinimumPeerVersion::with_mock_chain_tip`
An extension method useful for tests, that contains some shared
boilerplate code.
* Bias arbitrary `Version`s to be in valid range
Give a 50% chance for an arbitrary `Version` to be in the range of
previously used values the Zcash network.
* Create a `PeerVersions` helper type
Helps with the creation of mocked client services with arbitrary
protocol versions.
* Create a `PeerSetGuard` helper type
An auxiliary type to a `PeerSet` instance created for testing. It keeps
track of any dummy endpoints of channels created and passed to the
`PeerSet` instance.
* Create a `PeerSetBuilder` helper type
Helps to reduce the code when preparing a `PeerSet` test instance.
* Test if outdated peers are rejected by `PeerSet`
Simulate a set of discovered peers being sent to the `PeerSet`. Ensure
that only up-to-date peers are kept by the `PeerSet` and that outdated
peers are dropped.
* Create `BlockHeightPairAcrossNetworkUpgrades` type
A helper type that allows the creation of arbitrary block height pairs,
where one value is before and the other is at or after the activation
height of an arbitrary network upgrade.
* Test if peers are dropped as they become outdated
Simulate a network upgrade, and check that peers that become outdated
are dropped by the `PeerSet`.
* Remove dbg! macros
Co-authored-by: teor <teor@riseup.net>
* Use a single-thread shared Tokio runtime
This allows it to pause the time and more closely resembles the
environment that's set by default for asynchronous tests.
* Add a `zebra_test::init_async` helper function
Calls `zebra_test::init` but also constructs a single-thread Tokio
runtime and returns it. This makes it simpler to initialize asynchronous
tests that can't use the `#[tokio::test]` attribute.
* Replace usages of `Runtime::new` in tests
Use the new `zebra_test::init_async()` helper function instead.
* Replace `runtime::Builder::new_current_thread()`
Use the new `zebra_test::init_async()` helper function instead.
* Replace `runtime::Builder::new_multi_thread()`
Use the new `zebra_test::init_async()` helper function instead. The test
with the change doesn't necessarily have to use a multi-thread runtime.
* Revert "Remove commented-out code"
This reverts commit 9e69777925f103ee11e5940bba95b896c828839b.

* Use `MockService` in the basic mempool test
Refactor the `mempool_service_basic` test so that it uses a
`MockService` instead of the `mock_peer_set` helper function.
* Remove the `mock_peer_set` helper function
It is not used anymore, since the usages were replaced with
`MockService`s.
* add tests for mempool inbound requests
* Use MockService for transaction verifier
* Refactor creation of mock `peer_set`
Use the same style as the mock transaction verifier.
* Derive `Eq` for `zebra_network::Request`
Make it easy to use the `MockService::expect_request` method.
* Return mocked peer set service from `setup`
Allow it to be used to respond to requests.
* Add bindings for the transaction used for testing
Allow them to be moved into futures later.
* Respond to transaction download request
Make sure that the test transaction appears to the mempool as if it had
been downloaded by the peer set service.
* Assert that no unexpected requests were received
Check that the mempool doesn't send unexpected requests to the peer set
service.
* add tests for mempool inbound requests
* Use MockService for transaction verifier
* add missing `expect_no_requests` to `mempool_advertise_transaction_ids` test

* Rename internal network requests for wide transaction IDs
fastmod TransactionsByHash TransactionsById zebra*
fastmod AdvertiseTransactions AdvertiseTransactionIds zebra*
fastmod MempoolTransactions MempoolTransactionIds zebra*
fastmod TransactionHashes TransactionIds zebra*
* Update network transaction request/response comments
* Rename a transaction hash method for wide transaction IDs
fastmod transaction_hashes transaction_ids zebra-network
* Add UnminedTxId methods and conversions for InventoryHash
* Map WtxIds to unmined transaction network messages
Also, use UnminedTxId and UnminedTx in:
* Zebra's internal request and response format, and
* external Zcash network protocol messages.
* Enable WtxId mempool inventory tracking for peers
* Further clarify transaction IDs
* Use Witnessed rather than Wide for transaction IDs
And rename narrow to legacy when it only applies to v1-v4 transactions.
Otherwise, rename it to mined ID.
* Rename a missed binding
* Remove an incorrectly named binding

* Make the `AuthDigest` display order match transaction IDs
And derive `Hash`, just like transaction IDs.
Don't derive `serde` for now, because it's not needed.
* Move transaction::Hash test to tests module
* Add a simple AuthDigest display order test
* Add a WtxId type for wide transaction IDs
* Add conversions between transaction IDs and bytes
* Use the WtxId type in external network protocol messages
* Simplify state service initialization in test
Use the test helper function to remove redundant code.
* Create `BestTipHeight` helper type
This type abstracts away the calculation of the best tip height based on
the finalized block height and the best non-finalized chain's tip.
* Add `best_tip_height` field to `StateService`
The receiver endpoint is currently ignored.
* Return receiver endpoint from service constructor
Make it available so that the best tip height can be watched.
* Update finalized height after finalizing blocks
After blocks from the queue are finalized and committed to disk, update
the finalized block height.
* Update best non-finalized height after validation
Update the value of the best non-finalized chain tip block height after
a new block is committed to the non-finalized state.
* Update finalized height after loading from disk
When `FinalizedState` is first created, it loads the state from
persistent storage, and the finalized tip height is updated. Therefore,
the `best_tip_height` must be notified of the initial value.
* Update the finalized height on checkpoint commit
When a checkpointed block is commited, it bypasses the non-finalized
state, so there's an extra place where the finalized height has to be
updated.
* Add `best_tip_height` to `Handshake` service
It can be configured using the `Builder::with_best_tip_height`. It's
currently not used, but it will be used to determine if a connection to
a remote peer should be rejected or not based on that peer's protocol
version.
* Require best tip height to init. `zebra_network`
Without it the handshake service can't properly enforce the minimum
network protocol version from peers. Zebrad obtains the best tip height
endpoint from `zebra_state`, and the test vectors simply use a dummy
endpoint that's fixed at the genesis height.
* Pass `best_tip_height` to proto. ver. negotiation
The protocol version negotiation code will reject connections to peers
if they are using an old protocol version. An old version is determined
based on the current known best chain tip height.
* Handle an optional height in `Version`
Fallback to the genesis height in `None` is specified.
* Reject connections to peers on old proto. versions
Avoid connecting to peers that are on protocol versions that don't
recognize a network update.
* Document why peers on old versions are rejected
Describe why it's a security issue above the check.
* Test if `BestTipHeight` starts with `None`
Check if initially there is no best tip height.
* Test if best tip height is max. of latest values
After applying a list of random updates where each one either sets the
finalized height or the non-finalized height, check that the best tip
height is the maximum of the most recently set finalized height and the
most recently set non-finalized height.
* Add `queue_and_commit_finalized` method
A small refactor to make testing easier. The handling of requests for
committing non-finalized and finalized blocks is now more consistent.
* Add `assert_block_can_be_validated` helper
Refactor to move into a separate method some assertions that are done
before a block is validated. This is to allow moving these assertions
more easily to simplify testing.
* Remove redundant PoW block assertion
It's also checked in
`zebra_state::service::check::block_is_contextually_valid`, and it was
getting in the way of tests that received a gossiped block before
finalizing enough blocks.
* Create a test strategy for test vector chain
Splits a chain loaded from the test vectors in two parts, containing the
blocks to finalize and the blocks to keep in the non-finalized state.
* Test committing blocks update best tip height
Create a mock blockchain state, with a chain of finalized blocks and a
chain of non-finalized blocks. Commit all the blocks appropriately, and
verify that the best tip height is updated.
