4. Avoid repeated requests to peers after partial responses or errors (#3505)
* 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

* doc(network): fix a function doc typo

* doc(network): clarify how we handle peers that don't send `notfound`

* docs(network): clarify a test comment

3. Send notfound when Zebra doesn't have a block or transaction (#3466)
* 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,
at the cost of reducing coverage of different execution orders.

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.

* test(network): advertised routing is independent of numeric address value

* refactor(network): add InventoryStatus::marker() method to remove associated data

* fix(network): don't immediately rotate a new empty inventory registry

* fix(network): assert that only expected inventory variants are stored in the registry

* test(network): add a basic empty inventory registry test

Ignore unexpected block responses to fix error cascade when synchronizing blocks (#3374)
* 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.

Keep track of background peer tasks (#3253)
* Refactor to create heartbeat sender function

Move the code that's part of the heartbeat task into a separate helper
function.

* Move `Client` initialization down

Keep it closer to where it's actually used, and make it easier to add
new fields to `Client` for the connection and heartbeat tasks.

* Add background task handles to `Client` type

Prepare it to be able to check for panics or errors from the background
tasks.

* Add dummy background tasks to `ClientTestHarness`

Spawn simple timeout tasks as mock connection and heartbeat tasks.

* Fix `PeerSet` tests that use `ClientTestHarness`

Building a `ClientTestHarness` requires a Tokio runtime to be set up, so
the calls were moved into the `async` block.

* Refactor to create `set_task_exited_error`

Make the code reusable for both background tasks.

* Check heartbeat task for errors

Periodically poll it to check if the task has unexpectedly stopped.

* Check if connection background task has stopped

The client service should stop if the connection background task has
exited, because then it's not able to receive any replies.

* Allow aborting mocked `Client` background tasks

Wrap the background tasks in `Abortable`, so that they can be aborted
through the `ClientTestHarness`.

* Test if stopped connection task is detected

Check that stopping the background connection task is something that the
`Client` instance detects and handles correctly.

* Test if stopped heartbeat task is detected

Check that stopping the background heartbeat task is something that the
`Client` instance detects and handles correctly.

* Allow setting custom background tasks

Will be used later to create background tasks that panic.

* Test if `Client` handles panics in connection task

Use a mock background connection task that panics immediately, and check
that the `Client` handles it gracefully.

* Test if `Client` handles panics in heartbeat task

Use a mock background heartbeat task that panics immediately, and check
that the `Client` handles it gracefully.

* Change ticket referenced by `TODO`

The previously linked issue was a broad plan to improve Zebra's shutdown
behavior, while the new issue is more specific, and can be scheduled
sooner.

Use `MockedClientHandle` in other tests (#3241)
* Move `MockedClientHandle` to `peer` module

It's more closely related to a `Client` than the `PeerSet`, and this
prepares it to be used by other tests.

* Rename `MockedClientHandle` to `ClientTestHarness`

Reduce confusion, and clarify that the client is not mocked.

Co-authored-by: teor <teor@riseup.net>

* Add clarification to `mock_peers` documentation

Explicitly say how the generated data is returned.

* Rename method to `wants_connection_heartbeats`

The `Client` service only represents one direction of a connection, so
`is_connected` is not the exact term.

Co-authored-by: teor <teor@riseup.net>

* Mock `Client` instead of `LoadTrackedClient`

Move where the conversion from mocked `Client` to mocked
`LoadTrackedClient` in order to make the test helper more easily used by
other tests.

* Use `ClientTestHarness` in `initialize` tests

Replace the boilerplate code to create a fake `Client` instance with
usages of the `ClientTestHarness` constructor.

* Allow receiving requests from `Client` instance

Create a helper type to wrap the result, to make it easier to assert on
specific events after trying to receive a request.

* Allow inspecting the current error in the slot

Share the `ErrorSlot` between the `Client` and the handle, so that the
handle can be used to inspect the contents of the `ErrorSlot`.

* Allow placing an error into the `ErrorSlot`

Assuming it is initially empty. If it already has an error, the code
will panic.

* Allow gracefully closing the request receiver

Close the endpoint with the appropriate call to the `close()` method.

* Allow dropping the request receiver endpoint

Forcefully closes the endpoint.

* Rename field to `client_request_receiver`

Also rename the related methods to include
`outbound_client_request_receiver` to make it more precise.

Co-authored-by: teor <teor@riseup.net>

* Allow dropping the heartbeat shutdown receiver

Allows the `Client` to detect that the channel has been closed.

* Rename fn. to `drop_heartbeat_shutdown_receiver`

Make it clear that it affects the heartbeat task.

Co-authored-by: teor <teor@riseup.net>

* Move `NowOrLater` into a new `now-or-later` crate

Make it easily accessible to other crates.

* Add `IsReady` extension trait for `Service`

Simplifies checking if a service is immediately ready to be called.

* Add extension method to check for readiness error

Checks if the `Service` isn't immediately ready because a call to
`ready` immediately returns an error.

* Rename method to `is_failed`

Avoid negated method names.

Co-authored-by: teor <teor@riseup.net>

* Add a `IsReady::is_pending` extension method

Checks if a `Service` is not ready to be called.

* Use `ClientTestHarness` in `Client` test vectors

Reduce repeated code and try to improve readability.

* Create a new `ClientTestHarnessBuilder` type

A builder to create test `Client` instances using mock data which can be
tracked and manipulated through a `ClientTestHarness`.

* Allow configuring the `Client`'s mocked version

Add a `with_version` builder method.

* Use `ClientTestHarnessBuilder` in `PeerVersions`

Use the builder to set the peer version, so that the `version` parameter
can be removed from the constructor later.

* Use a default mock version where possible

Reduce noise when setting up the harness for tests that don't really
care about the remote peer version.

* Remove `Version` parameter from the `build` method

The `with_version` builder method should be used instead.

* Fix some typos and outdated info in the release checklist

* Add extra client tests for zero and multiple readiness checks (#3273)

And document existing tests.

* Replace `NowOrLater` with `futures::poll!` (#3272)

* Replace NowOrLater with the futures::poll! macro in zebrad

* Replace NowOrLater with the futures::poll! macro in zebra-test

* Remove the now-or-later crate

* remove unused imports

* rustfmt

Disconnect from outdated peers on network upgrade (#3108)
* 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.

Co-authored-by: teor <teor@riseup.net>

* 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

Add `zebra_test::init_async` helper function (#3169)
* 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.

Release Zebra v1.0.0-beta.2 (#3132)
Zebra's latest beta continues implementing zero-knowledge proof and note commitment tree validation. In this release, we have finished implementing transaction header, transaction amount, and Zebra-specific NU5 validation. (NU5 mainnet validation is waiting on an `orchard` crate update, and some consensus parameter updates.)

We also fix a number of security issues that could pose a local denial of service risk, or make it easier for an attacker to make a node follow a false chain.

As of this release, Zebra will automatically download and cache the Sprout and Sapling Groth16 circuit parameters. The cache uses around 1 GB of disk space. These cached parameters are shared across all Zebra and `zcashd` instances run by the same user.

See CHANGELOG.md for the full list of changes in this release.
