* Rename type parameter to be more explicit
Replace the single letter with a proper name.
* Remove imports for `Request` and `Response`
The type names will conflict with the ones for the mempool service.
* Attach `Mempool` service to the `Crawler`
Add a field to the `Crawler` type to store a way to access the `Mempool`
service.
* Forward crawled transactions to downloader
The crawled transactions are now sent to the transaction downloader and
verifier, to be included in the mempool.
* Derive `Eq` and `PartialEq` for `mempool::Request`
Make it simpler to use the `MockService::expect_request` method.
* Test if crawled transactions are downloaded
Create some dummy crawled transactions, and let the crawler discover
them. Then check if they are forwarded to the mempool to be downloaded
and verified.
* Don't send empty transaction ID list to downloader
Ignore response from peers that don't provide any crawled transactions.
* Log errors when forwarding crawled transaction IDs
Calling the Mempool service should not fail, so if an error happens it
should be visible. However, errors when downloading individual
transactions can happen from time to time, so there's no need for them
to be very visible.
* Document existing `mempool::Crawler` test
Provide some depth as to what the test expect from the crawler's
behavior.
* Refactor to create `setup_crawler` helper function
Make it easier to reuse the common test setup code.
* Simplify code to expect requests
Now that `zebra_network::Request` implement `Eq`, the call can be
simplified into `expect_request`.
* Refactor to create `respond_with_transaction_ids`
A helper function that checks for a network crawl request and responds
with the given list of crawled transaction IDs.
* Refactor to create `crawler_iterator` helper
A function to intercept and respond to the fanned-out requests sent
during a single crawl iteration.
* Refactor to create `respond_to_queue_request`
Reduce the repeated code necessary to intercept and reply to a request
for queuing transactions to be downloaded.
* Add `respond_to_queue_request_with_error` helper
Intercepts a mempool request to queue transactions to be downloaded, and
responds with an error, simulating an internal problem in the mempool
service implementation.
* Derive `Arbitrary` for `NetworkUpgrade`
This is required for deriving `Arbitrary` for some error types.
* Derive `Arbitrary` for `TransactionError`
Allow random transaction errors to be generated for property tests.
* Derive `Arbitrary` for `MempoolError`
Allow random Mempool errors to be generated for property tests.
* Test if errors don't stop the mempool crawler
The crawler should be robust enough to continue operating even if the
mempool service fails to download transactions or even fails to handle
requests to enqueue transactions.
* Reduce the log level for download errors
They should happen regularly, so there's no need to have them with a
high visibility level.
Co-authored-by: teor <teor@riseup.net>
* Stop crawler if service stops
If `Mempool::poll_ready` returns an error, it's because the mempool
service has stopped and can't handle any requests, so the crawler should
stop as well.

* Change assertion condition to match message
Refactor the condition so that the expression is easier to compare to
the panic message.
* Change comparison order to match panic message
Change the order of the equality so that it matches the panic message.
* Move mempool tests into `tests::vector` sub-module
Make it consistent with other test modules and prepare for adding
property tests.
* Reorder imports
Make it consistent with the general guidelines followed on other
modules.
* Export `ChainTipBlock` and `ChainTipSender`
Allow these types to be used in other crates for testing purposes.
* Derive `Arbitrary` for `ChainTipBlock`
Make it easy to generate random `ChainTipBlock`s for usage in property
tests.
* Refactor to move test methods into `tests` module
Reduce the repeated test configuration attributes and make it easier to
see what is test specific and what is part of the general
implementation.
* Add a `Mempool::dummy_call` test helper method
Performs a dummy call just so that `poll_ready` gets called.
* Use `dummy_call` in existing tests
Replace the custom dummy requests with the helper method.
* Test if the mempool is cleared on chain reset
A chain reset should force the mempool storage to be cleared so that
transaction verification can restart using the new chain tip.
* Test if mempool is cleared on syncer restart
If the block synchronizer falls behind and then starts catching up
again, the mempool should be disabled and therefore the storage should
be cleared.
* Add metrics gauges for the most recent peer network protocol version
This gague lets us join the initial seeds to the network protocol versions,
even if the peer upgrades and reconnects with a different version.
* Ensure dashboard peer network versions are unique
Otherwise, prometheus returns an error,
and the dashboard shows no data.
* Make seeder labels more readable
- put labels to the right of the graph
- remove default ports
Co-authored-by: Deirdre Connolly <deirdre@zfnd.org>
* Remove `std::error::Error` constraint
The generic `Error` type parameter doesn't have to implement the
standard `Error` trait, so having that constraint only unnecessarily
limits the types that can be used as an error for the service.
* Implement automatic conversion into `Error` type
Make the usage a little more ergonomic by not having to write manual
error type conversions.
* Add a documentation test for an error response
Show an example that responds to a call to the service with an error.

* Add `Transaction::spent_outpoints` getter method
Returns an iterator over the UTXO `OutPoint`s spent by the transaction.
* Add `mempool::Error::Conflict` variant
An error representing that a transaction was rejected because it
conflicts with another transaction that's already in the mempool.
* Reject conflicting mempool transactions
Reject including a transaction in the mempool if it spends outputs
already spent by, or reveals nullifiers already revealed by another
transaction in the mempool.
* Fix typo in documentation
Remove the `r` that was incorrectly added.
Co-authored-by: teor <teor@riseup.net>
* Specify that the conflict is a spend conflict
Make the situation clearer, because there are other types of conflict.
Co-authored-by: teor <teor@riseup.net>
* Clarify that the outpoints are from inputs
Because otherwise it could lead to confusion because it could also mean
the outputs of the transaction represented as `OutPoint` references.
Co-authored-by: teor <teor@riseup.net>
* Create `storage::tests::vectors` module
Refactor to follow the convention used for other tests.
* Add an `AtLeastOne::first_mut` method
A getter to allow changing the first element.
* Add an `AtLeastOne::push` method
Allow appending elements to the collection.
* Derive `Arbitrary` for `FieldNotPresent`
This is just to make the code that generates arbitrary anchors a bit
simpler.
* Test if conflicting transactions are rejected
Generate two transactions (either V4 or V5) and insert a conflicting
spend, which can be either a transparent UTXO, or a nullifier for one of
the shielded pools. Check that any attempt to insert both transactions
causes one to be accepted and the other to be rejected.
* Delete a TODO comment that we decided not to do

* `FindBlockHashes`
* `FindBlockHeaders`
* Test `FindBlock*` before and after the current block
* Add a specific test for bug #2789

* Send `Response::Nil` instead of sending empty `Message`s
This matches `zcashd`'s behaviour more closely.
In most cases, the network layer filters these out already.
But this change makes the the inbound service code clearer.
* revert changes made to `AdvertiseTransactionIds` and `PushTransaction`
* remove newline

* Remove return of redundant vector length
An attempt to improve readability a bit by not returning a tuple with a
value that can be obtained from a single return type.
* Refactor `unmined_transactions_in_blocks`
Use a more functional style to try to make it a bit clearer.
* Use ranges in `unmined_transactions_in_blocks`
Allow a finer control over the block range to extract the transactions
from.
* Refactor mempool test code to improve clarity
It was previously not clear that only the first genesis transaction was
being used. The remaining transactions in the genesis block were
discarded and then readded later.
* Replace `oneshot` with `call`
Remove a redundant internal `ready_and` call.
* Return an `impl Iterator` instead of a `Vec<_>`
Remove unnecessary deserializations and heap allocations.
* Refactor `mempool_storage_basic_for_network` test
Make the separation between the transactions expected to be in the
mempool and those expected to be rejected clearer.
* Replace `Iterator` with `DoubleEndedIterator`
Allow getting the last transaction more easily.

* 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
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

* Allow deliberate instances of the new nightly clippy::derivable_impls lint
We want our config defaults to be explicit.
Not so sure about the application defaults, but they also contain a config.
* Also allow unknown lint names
Stable doesn't know about this lint, but nightly does.
* 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.
