* Use the block verifier and non-finalized state in the cached state tests
This substantially increases test coverage.
Previously, the cached state tests were configured with
`checkpoint_sync = true`, which only uses the checkpoint
verifier and the finalized state.
* Log the source of blocks in commit_finalized_direct
This lets us check that we're actually testing the non-finalized state
and block verifier in the cached state tests.
It also improves diagnostics for state errors.
* Fail cached state tests if they're using incorrect heights or configs
This makes sure that the cached state tests actually test the transition
from checkpoint to block verification, and the non-finalized state.
* add legacy chain check and tests
* improve has_network_upgrade check
* add docs to legacy_chain_check()
* change arbitrary module structure
* change the panic message
* move legacy chain acceptance into existing tests
* use a reduced_branch_id_strategy()
* add docs to strategy function
* add argument to check for legacy chain into sync_until()
* 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
* 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

- Add a custom semver match for `zebrad` versions
- Prefer "line contains string" matches, so tests ignore minor changes
- Escape regex meta-characters when a literal string match is intended
- Rename test functions so they are more precise
- Rewrite match internals to remove duplicate code and enable custom matches
- Document match functions
* Standardise lints across Zebra crates, and add missing docs
The only remaining module with missing docs is `zebra_test::command`
* Todo -> TODO
* Clarify what a transcript ErrorChecker does
Also change `Error` -> `BoxError`
* TransError -> ExpectedTranscriptError
* Output Descriptions -> Output descriptions
`node2.is_running()` can return `true` on Windows, even though `node2`
has logged a panic. This cleanup code only runs if `node2` fails to panic
and exit as expected. So it's ok for us to skip it.
See #1781 for details.
On Windows, if a process is killed after it is dead, it returns `true`
for `was_killed`. Instead, check if the process is running before killing
it.
Also make the section where processes are running as short as possible,
and include context for both processes in every error.
* Increase the conflict acceptance test launch delay
Also rename the tests - the listener is for the Zcash protocol,
but the state, metrics, and tracing are Zebra-specific.

The clippy unknown lints attribute was deprecated in
nightly in rust-lang/rust#80524. The old lint name now produces a
warning.
Since we're using `allow(unknown_lints)` to suppress warnings, we need to
add the canonical name, so we can continue to build without warnings on
nightly.
But we also need to keep the old name, so we can continue to build
without warnings on stable.
And therefore, we also need to disable the "removed lints" warning,
otherwise we'll get warnings about the old name on nightly.
We'll need to keep this transitional clippy config until rustc 1.51 is
stable.
* Stop failing acceptance tests if their directories already exist
* Add an immutable config writing helper
and use it in the cached sapling acceptance tests.
Also:
* consistently create missing config and state directories
* refactor the common config writing code into a separate function
* only ignore NotFound errors in replace_config
* enforce config immutability using the type system
Check misconfigured ephemeral doesn't create a state dir
Add extra misconfigured `zebrad` ephemeral mode checks:
* doesn't create a state directory
* doesn't create unexpected files or directories in the working directory
Check ephemeral doesn't delete an existing state directory
Refactor all the ephemeral configs and checks into a single test
function.
Also:
* cleanup acceptance tests using utility functions
* make some checks consistent between tests
* make error messages consistent

This change avoids errors when tests are cancelled and re-run within a
short period of time, for example, using `cargo watch`.
It introduces a slight risk of port conflicts between the endpoint tests,
and with (ephemeral) ports used by other services. The risk of conflicts
across 2 tests is very low, and tests should be run in an isolated
environment on busy servers.
## Motivation
Prior to this PR we've been using `sled` as our database for storing persistent chain data on the disk between boots. We picked sled over rocksdb to minimize our c++ dependencies despite it being a less mature codebase. The theory was if it worked well enough we'd prefer to have a pure rust codebase, but if we ever ran into problems we knew we could easily swap it out with rocksdb.
Well, we ran into problems. Sled's memory usage was particularly high, and it seemed to be leaking memory. On top of all that, the performance for writes was pretty poor, causing us to become bottle-necked on sled instead of the network.
## Solution
This PR replaces `sled` with `rocksdb`. We've seen a 10x improvement in memory usage out of the box, no more leaking, and much better write performance. With this change writing chain data to disk is no longer a limiting factor in how quickly we can sync the chain.
The code in this pull request has:
- [x] Documentation Comments
- [x] Unit Tests and Property Tests
## Review
@hdevalence
* Use the default memory limit in the acceptance tests
PR #1233 changed the default `memory_cache_bytes`, but left the
acceptance tests with their old value.
* Run large checkpoint sync tests in CI
* Improve test child output match error context
* Add a debug_stop_at_height config
* Use stop at height in acceptance tests
And add some restart acceptance tests, to make sure the stop at
height feature works correctly.
* Reverse displayed endianness of transaction and block hashes
* fix zebra-checkpoints utility for new hash order
* Stop using "zebrad revhex" in zebrad-hash-lookup
* Rebuild checkpoint lists in new hash order
This change also adds additional checkpoints to the end of each list.
* Replace TransactionHash with transaction::Hash
This change should have been made in #905, but we missed Debug impls
and some docs.

Remove the seed command entirely, and make the behavior it provided
(responding to `Request::Peers`) part of the ordinary functioning of the
start command.
The new `Inbound` service should be expanded to handle all request
types.
* add test for first checkpoint sync
Prior this this change we've not had any tests that verify our sync /
network logic is well behaved. This PR cleans up the test helper code to
make error reports more consistent and uses this cleaned up API to
implement a checkpoint sync test which runs zebrad until it reads the
first checkpoint event from stdout.

* Split tracing component code into modules.
* Repatriate Tracing and simplify config handling.
We upstreamed our Tracing component, expecting not to have to exert fine
control over the tracing settings. But this turned out not to be the case, and
now that we want to do other things (flamegraphs, journalctl, opentelemetry,
etc), we end up with really awkward code (as in the current flamegraph
handling).
This also makes use of the changes to `init()` to load the config early to pass
configuration data into the components, which avoids the need for the
refactoring in #775.
Finally, we restore support for the `-v` flag when the filter is unset. Closes#831.
* Disable tracing and metrics endpoints by default.
Closes#660.
* Switch back to upstream Abscissa.
* Integrate flamegraph support into the new Tracing component.
* Pass -v in acceptance tests to get info-level output.
* Clean up acceptance test code.
* add zebrad acceptance tests
* add custom command test helpers that work with kill
* add and use info event for start and seed commands
* combine conflicting tests into one test case

* wip: start filter_handler impl
* Add .rustfmt.toml
* rustfmt
* Tidy up .rustfmt.toml
* Add filter reloading handling.
* bump toolchain
* Remove generated hello world acceptance tests.
These test the behaviour of the autogenerated binary and work as examples of
how to test the behaviour of abscissa binaries. Since we don't print "Hello
World" any more, they fail, but we don't yet have replacement behaviour to add
tests for, so they're removed for now.
* Clean up config file handling with Option::and_then.
