The mempool is only activated once, so we must check for that log first.
After mempool activation, the stop regex is logged at least once.
(It might be logged before as well, but we can't rely on that.)
When checking that the mempool didn't activate,
wait for the `zebrad` command to exit,
then check the entire log.

* 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): 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`

* 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.
* Support large block heights
* Document consensus rules referring to expiry heights
* Refactor the docs
* Apply suggestions from code review

* feat(network): send notfound messages to the inventory registry
* refactor(network): move the inventory filter into an async function
* feat(network): avoid routing requests to peers that are missing inventory
* test(network): advertised routing is independent of numeric address value
* test(network): peer set routes requests to peers not missing that inventory
* test(network): peer set fails requests if all ready peers are missing that inventory
* fix(clippy): needless-borrow in the peer set
* fix(lint): remove redundant trailing commas in macro calls
There is no clippy lint for this, maybe because some macros
are sensitive to trailing commas.
(But not the ones changed in this commit.)
* test(network): check the exact number of inventory peers
* doc(network): explain why we ignore inventory send failures
* docs(network): explain why a channel error is ignored
* 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.

* Avoid sequential borrows in `LatestChainTip`
Calling `watch::Receiver::borrow` more than once in the same scope can
cause a deadlock. The instrumented methods were calling `borrow` twice
to record instrumented fields.
This refactors things to ensure `borrow` is only called once to record
the fields and perform any actions with the chain tip block.
* Remove `borrow()` calls in `ChainTipChange`
Refactor to use a `LatestChainTip` instance instead, which safely
protects the internal `watch::Receiver` so that it is not borrowed more
than once in the same scope.
* Add a paragraph to the Asynchronous guide
Warn against using two borrow guards in the same scope, and describe why
that can lead to a deadlock.
* Use `testdir()` instead of `TempDir::new()`
Reduce repeated code and make it easier to change from using `tempdir`
to use `tempfile` instead.
* Replace `tempdir` with `tempfile` in `zebrad`
Use `tempfile`'s `TempDir` instead.
* Use `tempdir()` instead of `TempDir::new()`
Reduce repeated code and make it easier to upgrade to `tempfile`.
* Use `tempfile` instead of `tempdir`
Replace obsoleted `tempdir` dependency with `tempfile`.
* Use `tempfile` instead of `tempdir`

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.
