**Problem**
Forked console currently pulls in full Zinc, which includes JLine.
**Solution**
This implements a lighter-weight, full Java ForkConsoleMain,
which no longer depends on JLine.
Problem
When a user defines an alias with a name that matches an existing task or setting key (e.g., `alias c = compile` when a custom task `c` exists), the alias silently wins and shadows the task.
Solution
Detect conflicts at alias creation time and fail with an error message:
```
Alias 'c' conflicts with a task or setting key of the same name. Use a different alias name to avoid ambiguity.
```
Migrate the following test files from ScalaTest's AnyFlatSpec to
verify.BasicTestSuite, following the pattern established by other
test files in the sbt codebase:
- SizeParserSpec.scala (util-complete)
- MultiParserSpec.scala (main-command)
Changes in all files:
- Replace AnyFlatSpec class with BasicTestSuite object
- Convert 'should ... in' syntax to 'test(...)' syntax
- Use Scala 3 syntax with colon indentation
- Add 'end' markers
- Add explicit types where needed
Related to the ongoing test migration effort.
Fixes#8356
**Problem**
When `sbtn` sends a command while another long-running task (like `console`) is already executing, the client silently blocks with no indication that the command is waiting in a queue.
**Solution**
When a new command arrives via the network channel and another command is currently running, the server now sends an `ExecStatusEvent` notification with status `"Queued"` to the client. The client displays a message like:
```
[info] waiting for: console
```
Fixes#8538
The code was calling e.getMessage.contains() without checking if getMessage()
returns null. Changed to use Option(e.getMessage).exists() to safely handle
null values.
** 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
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
Previously, some additional code was used to parse the arguments to the
`help` command and ensure that the remaining commands were consistent
with the desired state of sbt.
While this code worked well in sbt 1.x, and was helpful in getting `sbt
help new` to work as expected, this does not work in sbt 2, and is
actually not required.
This patch removes the additional code, which fixes the `help` command
in sbt.
**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**
`run` task has been emulated via function call inside of a sandboxed classloader,
and blocking the command processing of sbt server loop.
This poses isolation and availability issues.
**Solution**
This implements client-side run where the server creates a sandbox environment, and sends the information to the client,
and the client forks a new JVM to perform the run.
The client-side behavior has been implemented in sbtn side already.
**Problem**
WHen portfile is not found, sbtn will try to start the server
even when the desired command is shutdown.
**Solution**
When the command is just shutdown, don't start the server.
**Problem**
`run` task blocks the server, but during the run the server is just
waiting for the built program to finish.
**Solution**
This implements client-side run where the server creates a sandbox
environment, and sends the information to the client,
and the client forks a new JVM to perform the run.
**Problem**
The sbtn response handling code is relatively stragightforward,
but it's a bit messy.
**Solution**
This cleans it up a bit, similar to the style used by Unfiltered
back then (not sure how Unfiltered plans are written nowadays) by
expressing each event handling as a partial function, and composing them
together using `orElse`.
**Problem**
Calling -bsp with --sbt-launch-jar causes "Unrecognized option: --server".
This is because --server is passed in twice since $7775
**Solution**
Since the server invocation by BSP client already passes in --server,
we can remove the extra --server append.
**Problem**
`run` currently blocks all other commands, such as BSP commands.
**Solution**
`run` no longer blocks the command execution loop.
Instead it pauses the prompt on the current command channel.
