* libs-scala/ports: Wrap socket ports in a type, `Port`.
* sandbox: Use `Port` for the API server port, and propagate.
CHANGELOG_BEGIN
CHANGELOG_END
* extractor: Use `Port` for the server port.
* ports: Make Port a compile-time class only.
* ports: Allow port 0; it can be specified by a user.
* ports: Publish to Maven Central.
* Avoid opening a server to the world when finding a free port.
This is very annoying on macOS because we get a focus-stealing popup for
a split second, asking for permission to allow the server through the
firewall. The popup pretty much always disappears before it can even be
read, when the server is closed.
This is almost certainly not an attack vector, because:
- we only do this in tests,
- the server is open for only a few milliseconds,
- nothing is served,
- and finding the port is tricky, because it's effectively random.
Nevertheless, it's very annoying.
CHANGELOG_BEGIN
CHANGELOG_END
* Extract a Bazel package for finding free ports.
We seem to do it in 4 different places, which I think is enough to
remove the duplication.
* sandbox: If the ledger ID isn't provided, use the one in the database.
Previously, we would fail if working against an existing ledger, and not
explicitly providing the ledger ID. This was the case even if the ledger
ID was randomly generated initially.
CHANGELOG_BEGIN
- [Sandbox] If no ledger ID is provided when running against an existing
ledger, use the existing ID. Previously, Sandbox would fail to start.
CHANGELOG_END
* sandbox: The ReadOnlySqlLedger should always receive a ledger ID.
It's read-only; it can't create one.
* sandbox: Stop using `equal` in SqlLedgerSpec.
* sandbox: Test that the ledger ID is as specified in SqlLedgerSpec.
* sandbox: Let the top-level runner handle a ledger ID mismatch.
And clean up the log text.
* sandbox: Initialize the ledger properly when the ID is dynamic.
* sandbox: Use `Vector`, not `List`, for SqlLedger initialization.
Append with Vector, good. List, bad.
* ledger-api-common: Make `LedgerApiMode.Dynamic` an object.
And add Java-style static factory methods.
* kvutils/app | ledger-on-{memory,sql}: Make `ledgerId` optional.
It should be generated or retrieved from the persistence layer by the
ledger itself.
* kvutils: Make the ledger ID optional in the tests.
* ledger-on-sql: Store the ledger ID, and reject conflicting IDs.
* ledger-on-sql: Make more things final.
* ledger-on-sql: Document the `ledger_meta.table_key` column better.
* sandbox: Don't hardcode the number of packages in the test DAR.
It changes.
* ledger-on-sql: Merge the `head` resource owner with the `dispatcher`.
* sandbox: Use backticks to simplify pattern match in ReadOnlySqlLedger.
* ledger-on-sql: Extract methods in `owner`.
* sandbox: Move more resource acquisition into the `owner`.
CHANGELOG_BEGIN
CHANGELOG_END
* sandbox: Reimplement SandboxClientResource as a resources.Resource.
* codegen: Use resources in TestUtil.
* sandbox: Manage PostgreSQL in tests with ResourceOwners.
* resources: Allow for startup exceptions without no stack trace.
* sandbox: Remove dependency duplication in the BUILD file.
* ledger-on-(memory|sql): Extract `Main` into its own file tree.
This is so we can remove the dependency on kvutils/app from the library.
logback.xml goes with it.
* sandbox: Implement "Sandbox Next" on top of ledger-on-sql.
CHANGELOG_BEGIN
- [Sandbox] Preliminary work to rebuild Sandbox on top of the DAML
Ledger Integration Kit. Currently not exposed through the CLI.
CHANGELOG_END
* ledger-on-sql: Publish to Maven Central.
* sandbox: If an unknown database is passed to Sandbox Next, handle it.
* resources: Catch errors in owner construction or acquisition.
Sometimes we're not in a future yet.
* resources: Don't run ProgramResource error handling inside the EC.
Otherwise we end up in deadlock which is only broken by
`awaitTermination` timing out.
* ledger-on-sql: Add a prefix of "ledger_" to the Flyway migrations table.
And while we're at it, make this a constant in the code and use Flyway
placeholders to substitute it in.
We don't have any users right now, so changing the migrations should be
fine.
CHANGELOG_BEGIN
CHANGELOG_END
* ledger-on-sql: Run the indexer on PostgreSQL when possible.
Specifically, when running the PostgreSQL conformance tests.
It will also work when running it as a binary, but you need to specify
both the `--server-jdbc-url` and `--jdbc-url` switches. This is to keep
kvutils/app simple.
* ledger-on-sql: Make `ExtraConfig` final.
Co-Authored-By: Stefano Baghino <43749967+stefanobaghino-da@users.noreply.github.com>
* resources: Revert `ResourceOwner.failed` to `ResourceOwner[Nothing]`.
Co-authored-by: Stefano Baghino <43749967+stefanobaghino-da@users.noreply.github.com>
* kvutils|ledger: Don't use Scala's global execution context.
I have just discovered that Scala's global execution context uses daemon
threads, which means they don't stick around past the end of the `main`
function. This is bad when application startup fails and we end up with
no other threads; the application terminates before it has a chance to
print the error message, which is very unhelpful.
We resolve this by creating a cached thread pool in the
`ProgramResource` class, specifically used for acquisition and release
of resources.
To do this, we need to pass the execution context through to the
resource constructors, which makes usage a little more verbose, because
now we can't use lambda functions (which can't take implicit arguments
such as the `executionContext`).
CHANGELOG_BEGIN
CHANGELOG_END
* kvutils-app|reference-v2: Sort `Runner` and `ReferenceServer` methods.
`App` is fairly problematic. It depends on `DelayedInit`, which is
deprecated because it has some surprising behavior.
Best to avoid it for anything more than a simple demo application.

CHANGELOG_BEGIN
CHANGELOG_END
* kvutils: Use `ResourceOwner#use` to simplify tests.
* kvutils: Merge in `RestartSpec` from ledger-on-sql.
CHANGELOG_BEGIN
- [KVUtils] Added a test case to the participant state tests to ensure
your ledger state is resumable upon restart.
CHANGELOG_END
* ledger-on-posix-filesystem: Extract paths into their own class.
* ledger-on-posix-filesystem: Seed the dispatcher with the correct head.
* kvutils: In participant state tests, be clear about different strings.
Co-authored-by: Samir Talwar <samir.talwar@digitalasset.com>
* resources: Throw upon acquiring the implicit ExecutionContext.
If we try and release an executor service which is itself being used to
power the releasing, we end up in a deadlock—the executor can't shut
down, and therefore `awaitTermination` never completes.
Fixing this is hard, but banning it is easy.
CHANGELOG_BEGIN
CHANGELOG_END
* resources: Explain a little more how the ExecutionContext check works.
Co-authored-by: Samir Talwar <samir.talwar@digitalasset.com>
* ledger-on-posix-filesystem: Run `scalafmt`.
* ledger-on-posix-filesystem: Just use file channel locks. Seriously.
* ledger-on-posix-filesystem: Rename `FileSystemLock#run` to `apply`.
* ledger-on-posix-filesystem: Conformance tests now run quickly.
So we can stop constraining the number of concurrent test runs.
* ledger-on-posix-filesystem: Lock the entire ledger with a file lock.
This ensures we can't have two separate ledger servers running against
the same directory.
This is mostly an experiment to better understand how to do this on an
SQL ledger for #4039.
CHANGELOG_BEGIN
CHANGELOG_END
* ledger-on-posix-filesystem: Run `scalafmt`.
* ledger-on-posix-filesystem: Use `Resource#use` in `FileSystemLock`.
* resources: Move `Resource#use` to `ResourceOwner#use`.
Makes more sense for the same object to govern both `acquire()` and
`release()`.
Co-authored-by: Samir Talwar <samir.talwar@digitalasset.com>
* resources: Make it easy to use a resource and then release it.
* ledger-on-sql: Move database transaction methods to `Database`.
* ledger-on-sql: Make sure the ledger picks up where it left off.
This means seeding the dispatcher with the correct head, rather than
starting at 1 every time.
CHANGELOG_BEGIN
CHANGELOG_END
* ledger-on-sql: Move `Index` and `StartIndex` to the package object.
They're used everywhere.
Co-authored-by: Samir Talwar <samir.talwar@digitalasset.com>
* ledger-on-sql: Pull out a superclass for the various integration tests.
* ledger-on-sql: Use Flyway to migrate tables in an idempotent manner.
CHANGELOG_BEGIN
CHANGELOG_END
* ledger-on-sql: Make it easy to run it with Bazel for experimentation.
* ledger-on-sql: Test that migrations will never change in the future.
* ledger-on-sql: Add a prefix of "ledger_" to the tables.
This is so we don't accidentally conflict with the index when the
schemas are shared.
I am letting myself modify the migrations because the existing
migrations haven't been merged into `master` yet.
* ledger-on-sql: Explain why we change the pool size after migration.
* ledger-api-test-tool: Tests now specify a timeout scale, not a timeout.
Makes it easier to change the default timeout in one place.
* ledger-api-test-tool: Increase timeouts on slow tests.
These tests produce a lot of volume and can make CI flaky.
* ledger-on-sql: Only tear down PostgreSQL in tests.
For other databases, we just create a new file for each test case.
* ledger-on-sql: Reduce the log output in tests.
* ledger-on-sql: Use a separate connection pool for Flyway when possible.
Apparently `setMaximumPoolSize` doesn't really have the desired effect
after the connection pool has already been used. The new test case will
be flaky if we process more than one commit in parallel.
For SQLite, it seems to be OK.
* ledger-on-sql: Use a separate connection pool for Flyway with SQLite.
Except in memory.
* ledger-on-sql: Use a separate PostgreSQL database for each test.
Because performance, innit. Don't have to tear them down.
* ledger-on-sql: Move the `Queries` values inside the `RDBMS` objects.
* ledger-on-sql: Go into even more detail about pool size hijinks.
Co-authored-by: Samir Talwar <samir.talwar@digitalasset.com>
* Add logging context information to ledger services
Rolls back that AllowedType implicit, which made the logging context
less usable and didn't provide that much of an advantage. Replaced with
helpers where it makes sense that take care of turning the value safely
into a string.

I have no idea why the build wasn't failing before.

* kvutils: Use resources in KeyValueParticipantState, not AutoCloseable.
CHANGELOG_BEGIN
- [kvutils] The simplified API now uses ``com.digitalasset.resources``
to manage acquiring and releasing resources instead of ``Closeable``.
CHANGELOG_END
* ledger-on-posix-filesystem: Remove dead code due to a refactoring fail.

Soooo much faster.
