* test: Migrate TrackedSpec.scala to verify.BasicTestSuite
Migrate TrackedSpec.scala from ScalaTest's AnyFlatSpec to
verify.BasicTestSuite, following the pattern established by other
test files in the sbt codebase.
Changes:
- Replace AnyFlatSpec class with BasicTestSuite object
- Convert 'should ... in' syntax to 'test(...)' syntax
- Use Scala 3 syntax with colon indentation
- Change === to == for assertions (BasicTestSuite style)
- Replace fail() with throw new AssertionError for explicit failures
- Add 'end TrackedSpec' marker
- Convert braces to colon-style for if expressions
** Problem **
The sbtn (sbt thin client) native image on Linux currently depends on glibc because ipcsocket uses JNI for Unix domain sockets. When building with musl for static linking, the JNI library fails to load since musl doesn't support `dlopen`.
** Solution **
Instead of upgrading to ipcsocket 2.x (which isn't ready for production), I created a `UnixDomainSocketFactory` that detects JDK 17+ at runtime and uses the native `java.net.UnixDomainSocketAddress` API directly via reflection. This completely bypasses JNI on modern JDKs.
For older JDKs (8 and 11), the factory falls back to ipcsocket 1.6.3, which is stable and well-tested.
** How It Works **
The factory checks at startup whether `java.net.UnixDomainSocketAddress` is available:
- **JDK 17+**: Uses native NIO Unix domain sockets (no JNI, no native libraries)
- **JDK 8/11**: Falls back to ipcsocket's JNI-based implementation
This approach:
- Enables musl static linking on JDK 17+ without any native dependencies
- Maintains full backward compatibility with older JDKs
- Keeps the stable ipcsocket 1.6.3 instead of the unstable 2.x
This adds a new setting that allows users to
configure Coursier's FileCache to cache local file:// artifacts. When enabled,
artifacts from local repositories are copied to the cache directory, which is
useful for scenarios like bundling compiler artifacts in a local repo for
offline use.
Fixes#7547
Set window title to 'sbt <command>: <org> % <name> % <version>' when
running sbt run, runMain, bgRun, or bgRunMain.
For server-side runs, window title is set directly. For client-side runs (sbtn), window title is passed via RunInfo protocol
and set by NetworkClient.
Fixes#7586
The publishLocalAllModule command fails with 'crossScalaVersions is
undefined' when the zinc submodule's compilerBridge project doesn't
have crossScalaVersions defined.
This is a long-standing issue that was reported in #4387 (2018) and
'magically resolved' when zinc happened to define the setting, then
resurfaced in #7607 (2024) when zinc changed.
The fix uses getOpt().getOrElse(Nil).toList instead of get().toList
to handle the case where crossScalaVersions is not defined, allowing
the command to proceed gracefully.
Fixes#7607
**Problem**
consoleProject doesn't work. REPL doesn't even start.
**Solution**
I made some progress into consoleProject.
At least Scala 3.7 repl session will now start.
The problem is that compiler bridge has not implemented binding,
so we can't forward the sbt build information into the repl.
**Problems**
When running forked tests, sbt uses `Runtime.getRuntime().availableProcessors()` to determine the thread pool size, ignoring `concurrentRestrictions`. This is inconsistent with non-forked parallel tests.
**Expectations**
Users should be able to control the number of parallel test threads in forked mode, similar to how `concurrentRestrictions` works for non-forked tests.
**Notes**
Added a new setting `testForkedParallelism` that allows explicit control:
```scala
testForkedParallelism := Some(2) // Use 2 threads
testForkedParallelism := None // Use availableProcessors() (default)
```
Eviction warnings and errors were not reported for Test dependencies because
`EvictionError` only checked the Compile configuration.
This fix runs the eviction check for both Compile and Test configurations
separately, with distinct error messages:
- Compile: `found version conflict(s) in library dependencies`
- Test: `found version conflict(s) in Test dependencies`
**Problem**
There's a disconnect between what is perceived to be the current
Scala version, and what sbt uses internally, and thus what it
chooses to be the default scalaVersion.
**Solution**
This displays a warning if scalaVersion setting is missing.

**Problem**
Compiler bridge resolution calls out to Coursier,
and it shows up on the profiler.
**Solution**
This uses sbt 2.x caching to cache the prebuilt compiler bridge binaries
to avoid calling Coursier from second time onwards.
**Problem**
sha256 is currently a bottleneck for no-op compilation.
**Solution**
This adds a local, in-memory cache of sha256 hashes of binary files
using their timestamp and file size.
The size of the digest cache can be configured using localDigestCacheByteSize,
which is set to 1MB by default.
**Problem**
Scala 3.8 REPL won't work since they've split the repl artifact into another JAR.
**Solution**
This works around it by creating a yet-another sandbox configuration ScalaReplTool
(similar to ScalaTool and ScalaDocTool) and a separate scalaInstance for
console task, so when Zinc is invoked we'll be able to conjure the right array of JARs.
