* Create a `MempoolBehavior` helper type
Prepare to replace the `Option<Height>` with a custom type that is more
flexible and provides more meaning when used.
* Use `MempoolBehavior` instead of `Option<Height>`
Clarify what the argument is, and prepare the code so that a new variant
can be added to the `MempoolBehavior` later.
* Allow the mempool to be automatically activated
Add a new variant to `MempoolBehavior` that indicates that the mempool
should become active during the test without needing a forced activation
height.
* Test full synchronization
Run `zebrad` and wait until full synchronization completes. Check if the
mempool is automatically activated when it reaches the tip.

Previously, the test would wait 10 seconds for the process to launch.
Now it waits until the process has used the conflicting resource.

* 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

* 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.
Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
* Log chain progress while Zebra is syncing
This helps test if the chain tip estimate is accurate,
and helps diagnose problems during full sync tests.
* Update to the latest chain tip estimate API
* 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.
* Use string literal to format unreachable message
* Try removing the redundant format

* fix(state): set state concurrency based on other services' concurrency
* fix(sync): increase the sync downloader lookahead limit
It seems like the recent tokio upgrade made this code even more efficient,
so on testnet we can have around 6000 blocks in flight.
Co-authored-by: mergify[bot] <37929162+mergify[bot]@users.noreply.github.com>
* feat(log): log the state tip height as part of sync progress logs
* fix(log): downgrade some verbose state logs to debug
* feat(log): log successful gossiped block verification at info level
These logs help us diagnose slow progress near the tip.
There won't be very many of these logs,
because they only happen near the tip.
* fix(log): spawn top-level tasks within the global Zebra tracing span
* fix(log): spawn blocking top-level tasks within the global Zebra tracing span

* 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

* Stop useless crawler attempts when there are no peers and no crawl responses
* Disable GitHub bug report URLs when the disk is full
* Add help text for the `zebrad start` tracing filter option
* 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.

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.
* Tweak a log message
* Only retry failed DNS once, then use the other DNS responses
* Limit broadcasts to half the peers
* Use a longer minimum interval for GetAddr requests
* Reduce the syncer and mempool crawler fanouts
* Stop resetting the mempool twice when it starts up
This spawns two crawlers, which send two fanouts,
so it can use up a lot of peers.

* Download and load Sprout parameters using zcash_proofs
Also update some librustzcash dependencies, to avoid duplicate dependencies.
* Update upstream orchard to avoid a compilation error
* Skip librustzcash batch refactor for now, to avoid compilation errors
* Change the cache ID, so we actually cache Sprout
* Move existing file checks into zcash_proofs
* Add a 1 hour timeout to parameter file downloads
* Give other tasks priority, before spawning the download task
* Update to the latest version of our modified librustzcash fork
* Change the cache key for Sprout
* Add 40 minutes to CI timeouts for occasional sprout downloads
* Update to zcash_proofs with split downloads
* Check file sizes to help debug parameter load failures in zcash_proofs
* Start the second download once the first has finished in zcash_proofs
* Document the parameter download task
* Stop hashing existing files twice
* Start network before verifiers
This makes the Groth16 download task start as late as possible.
* Explain why the Groth16 download must happen first
* Speed up Zebra shutdown: skip waiting for the tokio runtime
* Replace Zcash parameters crates with pre-downloaded local parameter files
* Download Zcash parameters using the `zcashd` script in CI and Docker
* Add a zcash_proofs dependency to zebra-consensus
* Download Sapling parameters using zcash_proofs, rather than fetch-params.sh
* Add a new `zebrad download` subcommand
This command isn't required for nomrmal usage.
But it's useful when testing, or launching multiple Zebra instances.
* Use `zebrad download` in CI to pre-download parameters
* Log a helpful hint if downloading fails
* Allow some duplicate dependencies currently hidden by orchard
* Spawn a separate task to download Groth16 parameters
* Run the parameter download with code coverage
This avoids re-compining Zebra with and without coverage.
* Update Cargo.lock after rebase
* Try to pass `download` as an argument to `zebrad` in coverage CI
* Fix copy and paste comment typos
* Add path and download examples, like zcash_proofs
* Download params in CI just like zcash_proofs does

```sh
fastmod SaplingParams SaplingParameters zebra*
fastmod Groth16Params Groth16Parameters zebra*
fastmod PARAMS GROTH16_PARAMETERS zebra*
fastmod params_folder directory zebra*
```
And a manual variable name tweak.
* rustfmt
* Remove a redundant coverage step

* Implement graceful shutdown for the peer set
* Use the minimum lookahead limit in acceptance tests
* Enable a doctest that compiles with newly public modules
* Revert "Remove commented-out code"
This reverts commit 9e69777925f103ee11e5940bba95b896c828839b.
* Implement deserialization for `addrv2` messages
* Limit addr and addrv2 messages to MAX_ADDRS_IN_MESSAGE
* Clarify address version comments
* Minor cleanups and fixes
* Add preallocation tests for AddrV2
* Add serialization tests for AddrV2
* Use prop_assert in AddrV2 proptests
* Use a generic utility method for deserializing IP addresses in `addrv2`
* Document the purpose of a conversion to MetaAddr
* Fix a comment typo, and clarify that comment
* Clarify the unsupported AddrV2 network ID error and enum variant names
```sh
fastmod AddrV2UnimplementedError UnsupportedAddrV2NetworkIdError zebra-network
fastmod Unimplemented Unsupported zebra-network
```
* Fix and clarify unsupported AddrV2 comments
* Replace `panic!` with `unreachable!`
* Clarify a comment about skipping a length check in a test
* Remove a redundant test
* Basic addr (v1) and addrv2 deserialization tests
* Test deserialized IPv4 and IPv6 values in addr messages
* Remove redundant io::Cursor
* Add comments with expected values of address test vectors
* Update `tower` to version `0.4.9`
Update to latest version to add support for Tokio version 1.
* Replace usage of `ServiceExt::ready_and`
It was deprecated in favor of `ServiceExt::ready`.
* Update Tokio dependency to version `1.13.0`
This will break the build because the code isn't ready for the update,
but future commits will fix the issues.
* Replace import of `tokio::stream::StreamExt`
Use `futures::stream::StreamExt` instead, because newer versions of
Tokio don't have the `stream` feature.
* Use `IntervalStream` in `zebra-network`
In newer versions of Tokio `Interval` doesn't implement `Stream`, so the
wrapper types from `tokio-stream` have to be used instead.
* Use `IntervalStream` in `inventory_registry`
In newer versions of Tokio the `Interval` type doesn't implement
`Stream`, so `tokio_stream::wrappers::IntervalStream` has to be used
instead.
* Use `BroadcastStream` in `inventory_registry`
In newer versions of Tokio `broadcast::Receiver` doesn't implement
`Stream`, so `tokio_stream::wrappers::BroadcastStream` instead. This
also requires changing the error type that is used.
* Handle `Semaphore::acquire` error in `tower-batch`
Newer versions of Tokio can return an error if the semaphore is closed.
This shouldn't happen in `tower-batch` because the semaphore is never
closed.
* Handle `Semaphore::acquire` error in `zebrad` test
On newer versions of Tokio `Semaphore::acquire` can return an error if
the semaphore is closed. This shouldn't happen in the test because the
semaphore is never closed.
* Update some `zebra-network` dependencies
Use versions compatible with Tokio version 1.
* Upgrade Hyper to version 0.14
Use a version that supports Tokio version 1.
* Update `metrics` dependency to version 0.17
And also update the `metrics-exporter-prometheus` to version 0.6.1.
These updates are to make sure Tokio 1 is supported.
* Use `f64` as the histogram data type
`u64` isn't supported as the histogram data type in newer versions of
`metrics`.
* Update the initialization of the metrics component
Make it compatible with the new version of `metrics`.
* Simplify build version counter
Remove all constants and use the new `metrics::incement_counter!` macro.
* Change metrics output line to match on
The snapshot string isn't included in the newer version of
`metrics-exporter-prometheus`.
* Update `sentry` to version 0.23.0
Use a version compatible with Tokio version 1.
* Remove usage of `TracingIntegration`
This seems to not be available from `sentry-tracing` anymore, so it
needs to be replaced.
* Add sentry layer to tracing initialization
This seems like the replacement for `TracingIntegration`.
* Remove unnecessary conversion
Suggested by a Clippy lint.
* Update Cargo lock file
Apply all of the updates to dependencies.
* Ban duplicate tokio dependencies
Also ban git sources for tokio dependencies.
* Stop allowing sentry-tracing git repository in `deny.toml`
* Allow remaining duplicates after the tokio upgrade
* Use C: drive for CI build output on Windows
GitHub Actions uses a Windows image with two disk drives, and the
default D: drive is smaller than the C: drive. Zebra currently uses a
lot of space to build, so it has to use the C: drive to avoid CI build
failures because of insufficient space.

* Revert "Avoid spurious test failures on busy machines"
This reverts commit 4430a48ef3.
* Increase request delay for mock network service
This is necessary because some tests were having timeouts when running
on macOS for the CI. This meant that it took longer than expected for
the subject under test to end up sending the network request.

* Try simulating a chain growth
* Adjust the transaction expiry height
The mempool evicts expired transactions. When working with mocked data,
appending a new block typically clears the mempool because transactions become
expired. For this reason, the expiry height of each transactions is adjusted so
that it is greater than the new chain tip's height.
* Refactor the code so that it works with `VerifiedUnminedTx`
* Fix a typo
* Fix clippy warnings

There are a lot of these messages when Zebra starts up.
They might be slowing down CI and causing timeouts.

This matches the settings for `sync_large_checkpoints_mainnet`.
Also reduce the number of blocks synced to reduce network load.

* Create a `NowOrLater` helper type
A replacement for `FutureExt::now_or_never` that ensures that the task
is scheduled for waking up later when the inner future is ready.
* Use `NowOrLater` to fix possible delay bug
Previous usage of `now_or_never` meant that the underlying task wasn't
being scheduled to awake when the `Downloads` stream produced a new
item. Using `NowOrLater` instead fixes that issue.
* Increase the restart test timeout to 10 seconds
It shouldn't take this long.
But maybe the CI VMs are under a lot of load?
* Add extensive logging to diagnose CI state reload failures
* Ignore AlreadyInChain error in the syncer
* Split Cancelled errors; add them to should_restart_sync exceptions
* Also filter 'block is already comitted'; try to detect a wrong downcast
* Rename tx downloader & verifier metrics
* Add version to mempool metrics
* Add new metrics
* Make sure mempool gauges are zeroed when instances are dropped
* Updated mempool grafana dashboard

* Guarantee unique IDs in mempool service responses
* Guarantee unique IDs in crawler task mempool Queue requests
Also update the tests to use unique IDs.
* Add a CheckForVerifiedTransactions mempool request
Also document the mempool request and response variants.
* Spawn a QueueChecker task to check for newly verified transactions
This task makes sure that transactions reliably propagate,
rather than relying on peer requests or responses to trigger propagation.
* Update the start command documentation

* Get the transaction fee from utxos
* Return the transaction fee from the verifier
* Avoid calculating the fee for coinbase transactions
Coinbase transactions don't have fees. In case of a coinbase transaction, the
verifier returns a zero fee.
* Update the result obtained by `Downloads`
