In newer Tokio versions the `Sleep` type doesn't implement `Unpin`, so
it needs to be manually pinned.
There are a lot of these messages when Zebra starts up.
They might be slowing down CI and causing timeouts.

* Fix a comment typo
Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com>
Co-authored-by: Alfredo Garcia <oxarbitrage@gmail.com>
Newer versions of Tokio panic if `tokio::time::pause()` is called from a
multi-thread executor, and `#[tokio::test]` defaults to a single thread
runtime, so it makes sense to always use a single thread runtime in all
tests.
In newer Tokio versions the `Sleep` type doesn't implement `Unpin`, so
it's a little more complicated to use it. In this case it was easier to
refactor the code to not store the `Sleep` type instead of wrapping it
in a `Pin` type.

* Use `MockService` in inbound test
Refactor the `mempool_requsets_for_transactions` test so that it uses a
`MockService` instead of the `mock_peer_set` function.
* 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

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

* Implement initial service mocking helpers
Adds a [`MockService`] type, which can be configured and built for usage
in unit tests or proptests. The mocked service can then be used to
intercept requests and respond indivdiually to them.
* Use `MockService in the `mempool::Crawler` test
Refactor it to remove the helper mock function, and use the new
`MockService` helper type.
* Use `MockService` in `CandidateSet` test vectors
Refactor to remove the manual mocking of the peer set service.
* Panic if a response is not sent by `MockService`
Change the current semantics to require all `MockService` usages to
respond to every intercepted request.
A `must_use` attribute was added to the `ResponseSender` so that the
compiler can warn when this doesn't happen.
* Allow generic error types in `MockService`
Replace the hard-coded `BoxError` as the `Service`'s error type with a
generic type parameter. This allows mocking services in locations that
require specific error types.
* Add a `ResponseSender::request` getter
Allow inspecting the request again before responding, and using
information from the request in the response.

`Message::Inv(TxId+)` is a transaction advertisement,
so it should be converted into `Request::AdvertiseTransactionIds`.
This is a copy-paste mistake from the original zebra-network
implementation.
* 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
Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
* 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.

* Rename constant to `MIN_INVENTORY_HASH_SIZE`
Because the size is not constant anymore, since the `MSG_WTX` inventory
type is larger.
* Add `InventoryHash::smallest_types_strategy`
A method for a proptest strategy that generates the `InventoryHash`
variants that have the smallest serialized size.
* Update proptest to use only smallest inventories
In order to properly test the maximum allocation.
* Add intra-doc links in some method documentation
Make it easier to navigate from the documentation of the proptest
strategies to the variants they generate.
* Parse `MSG_WTX` inventory type
Avoid returning an error if a received `GetData` or `Inv` message
contains a `MSG_WTX` inventory type. This prevents Zebra from
disconnecting from peers that announce V5 transactions.
* Fix inventory hash size proptest
The serialized size now depends on what type of `InventoryHash` is being
tested.
* Implement serialization of `InventoryHash::Wtx`
For now it just copies the stored bytes, in order to allow the tests to
run correctly.
* Test if `MSG_WTX` inventory is parsed correctly
Create some mock input bytes representing a serialized `MSG_WTX`
inventory item, and check that it can be deserialized successfully.
* Generate arbitrary `InventoryHash::Wtx` for tests
Create a strategy that only generates `InventoryHash::Wtx` instances,
and also update the `Arbitrary` implementation for `InventoryHash` to
also generate `Wtx` variants.
* Test `InventoryHash` serialization roundtrip
Given an arbitrary `InventoryHash`, check that it does not change after
being serialized and deserialized.
Currently, `InventoryHash::Wtx` can't be serialized, so this test will
is expected to panic for now, but it will fail once the serialization
code is implemented, and then the `should_panic` should be removed.
* Test deserialize `InventoryHash` from random bytes
Create an random input vector of bytes, and try to deserialize an
`InventoryHash` from it. This should either succeed or fail in an
expected way.
* Remove redundant attribute
The attribute is redundant because the `arbitrary` module already has
that attribute.
* Implement `Message::inv_strategy()`
A method to return a proptest strategy that creates `Message::Inv`
instances.
* Implement `Message::get_data_strategy()`
A method that returns a proptest strategy that creates
`Message::GetData` instances.
* Test encode/decode roundtrip of some `Message`s
Create a `Message` instance, encode it and then decode it using a
`Codec` instance and check that the result is the same as the initial
`Message`.
For now, this only tests `Message::Inv` and `Message::GetData`, because
these are the variants that are related to the scope of the current set
of changes to support parsing the `MSG_WTX` inventory type.
Even so, the test relies on being able to serialize an
`InventoryHash::Wtx`, which is currently not implemented. Therefore the
test was marked as `should_panic` until the serialization code is
implemented.
* Update versions for zebra v1.0.0-alpha.12 release
* Update Cargo.lock
* Update release checklist with latest version changes to help keep track for future releases
* Remove reference to the fact that tower-fallback was not updated
* Rename some methods and constants for clarity
Using the following commands:
```
fastmod '\bis_ready_for_attempt\b' is_ready_for_connection_attempt
# One instance required a tweak, because of the ASCII diagram.
fastmod '\bwas_recently_live\b' has_connection_recently_responded
fastmod '\bwas_recently_attempted\b' was_connection_recently_attempted
fastmod '\bwas_recently_failed\b' has_connection_recently_failed
fastmod '\bLIVE_PEER_DURATION\b' MIN_PEER_RECONNECTION_DELAY
```
* Use `Instant::elapsed` for conciseness
Instead of `Instant::now().saturating_duration_since`. They're both
equivalent, and `elapsed` only panics if the `Instant` is somehow
synthetically generated.
* Allow `Duration32` to be created in other crates
Export the `Duration32` from the `zebra_chain::serialization` module.
* Add some new `Duration32` constructors
Create some helper `const` constructors to make it easy to create
constant durations. Add methods to create a `Duration32` from seconds,
minutes and hours.
* Avoid gossiping unreachable peers
When sanitizing the list of peers to gossip, remove those that we
haven't seen in more than three hours.
* Test if unreachable addresses aren't gossiped
Create a property test with random addreses inserted into an
`AddressBook`, and verify that the sanitized list of addresses does not
contain any addresses considered unreachable.
* Test if new alternate address isn't gossipable
Create a new alternate peer, because that type of `MetaAddr` does not
have `last_response` or `untrusted_last_seen` times. Verify that the
peer is not considered gossipable.
* Test if local listener is gossipable
The `MetaAddr` representing the local peer's listening address should
always be considered gossipable.
* Test if gossiped peer recently seen is gossipable
Create a `MetaAddr` representing a gossiped peer that was reported to be
seen recently. Check that the peer is considered gossipable.
* Test peer reportedly last seen in the future
Create a `MetaAddr` representing a peer gossiped and reported to have
been last seen in a time that's in the future. Check that the peer is
considered gossipable, to check that the fallback calculation is working
as intended.
* Test gossiped peer reportedly seen long ago
Create a `MetaAddr` representing a gossiped peer that was reported to
last have been seen a long time ago. Check that the peer is not
considered gossipable.
* Test if just responded peer is gossipable
Create a `MetaAddr` representing a peer that has just responded and
check that it is considered gossipable.
* Test if recently responded peer is gossipable
Create a `MetaAddr` representing a peer that last responded within the
duration a peer is considered reachable. Verify that the peer is
considered gossipable.
* Test peer that responded long ago isn't gossipable
Create a `MetaAddr` representing a peer that last responded outside the
duration a peer is considered reachable. Verify that the peer is not
considered gossipable.
* Disable IPv6 tests when $ZEBRA_SKIP_IPV6_TESTS is set
This allows users to disable IPv6 tests in environments where IPv6 is not
configured.
* Add network test env var constants
* Replace env strings with constants
fastmod '"ZEBRA_SKIP_NETWORK_TESTS"' zebra_test::net::ZEBRA_SKIP_NETWORK_TESTS
fastmod '"ZEBRA_SKIP_IPV6_TESTS"' zebra_test::net::ZEBRA_SKIP_IPV6_TESTS
* Add functions to skip network tests
* Replace test network env var checks with test function
fastmod --fixed-strings 'env::var_os(zebra_test::net::ZEBRA_SKIP_NETWORK_TESTS).is_some()' 'zebra_test::net::zebra_skip_network_tests()'
fastmod --fixed-strings 'env::var_os(zebra_test::net::ZEBRA_SKIP_IPV6_TESTS).is_some()' 'zebra_test::net::zebra_skip_ipv6_tests()'
* Remove redundant logging and use statements
* Support a min protocol version during initial block download
But don't actually use the state height yet.
Also rename some functions and constants.

* README: update known issues
* Add ticket numbers
* Add network ports to README
* Make heading a bit clearer
* Update zebra listener address docs
Explain how Zebra currently uses listener addresses,
after recent changes.
* Gossip dynamically allocated listener ports to peers
Previously, Zebra would either gossip port `0`, which is invalid, or skip
gossiping its own dynamically allocated listener port.
* Improve "no configured peers" warning
And downgrade from error to warning, because inbound-only nodes are a
valid use case.
* Move random_known_port to zebra-test
* Add tests for dynamic local listener ports and the AddressBook
Co-authored-by: Janito Vaqueiro Ferreira Filho <janito.vff@gmail.com>
* Always send our local listener with the latest time
Previously, whenever there was an inbound request for peers, we would
clone the address book and update it with the local listener.
This had two impacts:
- the listener could conflict with an existing entry,
rather than unconditionally replacing it, and
- the listener was briefly included in the address book metrics.
As a side-effect, this change also makes sanitization slightly faster,
because it avoids some useless peer filtering and sorting.
* Skip listeners that are not valid for outbound connections
* Filter sanitized addresses Zebra based on address state
This fix correctly prevents Zebra gossiping client addresses to peers,
but still keeps the client in the address book to avoid reconnections.
* Add a full set of DateTime32 and Duration32 calculation methods
* Refactor sanitize to use the new DateTime32/Duration32 methods
* Security: Use canonical SocketAddrs to avoid duplicate connections
If we allow multiple variants for each peer address, we can make multiple
connections to that peer.
Also make sure sanitized MetaAddrs are valid for outbound connections.
* Test that address books contain the local listener address
