* Use a named CancelHeartbeatTask unit struct for the channel type
* Prefer cancel handles in selects, if both are ready
* Fix message metrics to just show the command name
* Add metrics for internal requests and responses
* Add internal requests and responses to the messages dashboard
* Add a canceled metric, and peer addresses to request and response metrics
* Add a canceled messages graph
* Add connection state metrics for currently open connections
* Fix the connection state graph with new metrics
* Always send an error before dropping pending responses
* Move error detail logging into `fail_with`
* 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
* 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.
* Refactor the address response limit
* Limit the number of peers in the address book
* Allow changing the address book limit in tests
* Add tests for the address book length limit
* rustfmt
* Stop checking the entire AddressBook for each connection attempt
* Stop redundant peer time checks within the address book
* Stop calling `Instant::now` 3 times for each address book update
* Only get the time once each time an address book method is called
* Update outdated comment
* Use an OrderedMap to efficiently store address book peers
* Add address book order tests
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
* Delete a redundant build step
* Implement graceful shutdown for zebrad start
* Send coverage summary to /dev/null when getting the params path
* Use the correct parameters path and download commands in CI
* Explain pre-downloads
* Avoid calling params_folder twice
* Rename parameter types and methods for consistency
```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.

* Avoid spurious test failures on busy machines
* Revert "Avoid spurious test failures on busy machines"
This reverts commit 4430a48ef3d20ceddf737a2f2741638875b0148c.
* 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.

* Increase test timeout for Windows builds
Co-authored-by: teor <teor@riseup.net>
Co-authored-by: Conrado Gouvea <conrado@zfnd.org>
* 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.
Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
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
