This timeout stops the sync service hanging when it is missing required
blocks, but the lookahead queue is full of dependent verify tasks, so the
missing blocks never get downloaded.
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

* Add the configured network to error reports
* Log the configured network at error level
* Create the global span immediately after activating tracing
And leak the span guard, so the span is always active.
* Include panic metadata in the report and URL
* Use `Main` and `Test` in the global span
`net=Mainnet` is a bit redundant
When `cargo run` is run in the workspace directory, it can see two
executables:
- `zebrad`
- `zebra_checkpoints`
Adding `default-run = "zebrad"` to `zebrad/Cargo.toml` makes the
workspace run `zebrad` by default. (Even though it's redundant for the
`zebrad` crate itself.)
* Rewrite GetData handling to match the zcashd implementation
`zcashd` silently ignores missing blocks, but sends found transactions
followed by a `NotFound` message:
e7b425298f/src/main.cpp (L5497)
This is significantly different to the behaviour expected by the old
Zebra connection state machine, which expected `NotFound` for blocks.
Also change Zebra's GetData responses to peer request so they ignore
missing blocks.
* Stop hanging on incomplete transaction or block responses
Instead, if the peer sends an unexpected block, unexpected transaction,
or NotFound message:
1. end the request, and return a partial response containing any items
that were successfully received
2. if none of the expected blocks or transactions were received, return
an error, and close the connection
In our README, we tell users to ignore these errors, so we should also
disable the issue URL.
Also include the hash in the error. (We don't want the span active for
all messages, we just want the hash in the error.)
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.
vergen's implementation of REBUILD_ON_HEAD_CHANGE assumes that the .git
directory is in the crate root, but Zebra uses a workspace.
Temporary fix for rustyhorde/vergen#21.
Because the new version of the prometheus exporter launches its own
single-threaded runtime on a dedicated worker thread, there's no need
for the tokio and hyper versions it uses internally to align with the
versions used in other crates. So we don't need to use our fork with
tokio 0.3, and can just use the published alpha. Advancing to a later
alpha may fix the missing-metrics issues.
As we approach our alpha release we've decided we want to plan ahead for the user bug reports we will eventually receive. One of the bigger issues we foresee is determining exactly what version of the software users are running, and particularly how easy it may or may not be for users to accidentally discard this information when reporting bugs.
To defend against this, we've decided to include the exact git sha for any given build in the compiled artifact. This information will then be re-exported as a span early in the application startup process, so that all logs and error messages should include the sha as their very first span. We've also added this sha as issue metadata for `color-eyre`'s github issue url auto generation feature, which should make sure that the sha is easily available in bug reports we receive, even in the absence of logs.

* implement inbound `FindBlocks`
* Handle inbound peer FindHeaders requests
* handle request before having any chain tip
* Split `find_chain_hashes` into smaller functions
Add a `max_len` argument to support `FindHeaders` requests.
Rewrite the hash collection code to use heights, so we can handle the
`stop` hash and "no intersection" cases correctly.
* Split state height functions into "any chain" and "best chain"
* Rename the best chain block method to `best_block`
* Move fmt utilities to zebra_chain::fmt
* Summarise Debug for some Message variants
