Fix all IntelliJ warnings in Java production code except for
bogus spelling warnings and warnings about unused public methods.
Also fix some warnings emitted by Code->Inspect Code.
Changes made:
- use text block instead of string concatenation
- extract method to avoid code duplication
- use switch expression
- fix Javadoc syntax and spelling
- fix spelling in comment
- increase class visibility to match visibility of use site
- delete overriding method with same implementation
- use String.isEmpty() and StringBuilder.isEmpty()
- add @Serial annotation
- make field final
- remove unused field
- remove unused private method
- remove exceptions that aren't thrown from throws clause
- insert non-null assertion
- annotate overriding method with @Nonnull
- suppress warning
- delete unused class (WriteAuxiliarySlotNode)
- add final modifier
- remove unused error message
- repeat @Nullable modifier in overriding method
- remove never thrown exception from throws clause
- remove redundant suppression
- Refactor code to use the following basic Java 17 features:
- pattern matching for instanceof
- @Serial annotation
- switch expressions
- enhanced switch statements
- StringBuilder.isEmpty()
- Replace two switch statements with simpler if statements.
- Rename a few local variables.
This is a comprehensive solution to the "flaky PackageServer tests"
problem. It rules out port conflicts and imposes no limits on test
parallelism. The same solution can be used for other test servers
in the future.
Major changes:
- Turn `PackageServer` from a singleton into a class that is
instantiated per test class or test method.
- Start the server the first time its `port` property is read.
Bind the server to an ephemeral port instead of port 12110.
- For every test that uses `PackageServer`, pass the server port to
`--test-port`, `HttpClient.Builder.setTestPort`, the `CliBaseOptions`
or `ExecutorOptions` constructor, or the Gradle plugin's `testPort` property.
Wire all of these to `RequestRewritingClient`'s `testPort` constructor parameter.
- Enhance `RequestRewritingClient` to replace port 12110 with `testPort`
in request URIs unless `testPort` is -1 (its default).
- Introduce `ExecutorOptions.Builder`.
This makes executor options more comfortable to create
and allows to hide options such as `testPort`.
- Deprecate the `ExecutorOptions` constructor to steer users towards the builder.
- Get rid of `ExecutorOptions2`, which is no longer needed.
- Clean up `EmbeddedExecutorTest` with the help of the builder.
* pkl-excutor tests: symlink 0.25.0 distribution into pkl-executable/build
* Use `IoUtils.getPklHomeDir` in HttpClientBuilder
* Simplify Exceptions.java
* Enable testing for older pkl-executor distribution
Moving to java.net.http.HttpClient brings many benefits, including
HTTP/2 support and the ability to make asynchronous requests.
Major additions and changes:
- Introduce a lightweight org.pkl.core.http.HttpClient API.
This keeps some flexibility and allows to enforce behavior
such as setting the User-Agent header.
- Provide an implementation that delegates to java.net.http.HttpClient.
- Use HttpClient for all HTTP(s) requests across the codebase.
This required adding an HttpClient parameter to constructors and
factory methods of multiple classes, some of which are public APIs.
- Manage CA certificates per HTTP client instead of per JVM.
This makes it unnecessary to set JVM-wide system/security properties
and default SSLSocketFactory's.
- Add executor v2 options to the executor SPI
- Add pkl-certs as a new artifact, and remove certs from pkl-commons-cli artifact
Each HTTP client maintains its own connection pool and SSLContext.
For efficiency reasons, It's best to reuse clients whenever feasible.
To avoid memory leaks, clients are not stored in static fields.
HTTP clients are expensive to create. For this reason,
EvaluatorBuilder defaults to a "lazy" client that creates the underlying
java.net.http.HttpClient on the first send (which may never happen).
