The jline 3 Terminal is an autocloseable and should be closed when we're
down with it. I'm not exactly sure what resources we were potentially
leaking, but the jline3term variable is an instance of the jline
AbstractTerminal class which I know can create a thread in some
circumstances. This came up while working on #6185.
Made the bspConfig task dependendant on the bspConfig value.
Changed the bspConfig setting to use a attributeKey so we can use it in the server as well.
The waitWatch command is very similar to shell in that it should
override the onFailure command to be itself. It also enqueues itself to
remaining commands whenever it reads a new command which made it
unnecessary to append waitWatch to the runCommmand in Continuous.
It is possible for the signal handler to get in a state where it has no
effect in the shell. When this happens, entering ctrl+c does not exit
the shell. To ensure that ctrl+c always exits the shell, we can register
a signal handler in the line reader that write -1 to the terminal input
stream, which should cause the line reader to return an exit command.
There are cases where sbt will incorrectly shutdown if the jline reader
is interrupted while filling the input buffer. To fix this we can throw
an InterruptedException instead of a ClosedException.
The repro for this was start `sbt`, input `~compile` and while sbt was
starting up, open a source file with vim using the metals bsp
integration. sbt server would end up shutting down everytime after a
single compilation iteration.
The new version provides an apple silicon arm64 jni implementation of
the ipcsocket api. It also adds a jni implementation for getting the max
socket length which is necessary because jna isn't supported on the
apple arm64 platform yet.
When a user returns to the shell with 's' in recent versions of sbt, the
prompt is not initially displayed. This ends up being because MainLoop
was incorrectly setting the terminal prompt to Prompt.Watch when it
exited watch. I realized in debugging the issue that it didn't make
sense to restort the terminal prompt to the initial value before task
evaluation. By removing that logic, the 's' option option started
working correctly again.
There isn't yet a version of the jna available that works with the new
apple silicon using arm64. To workaround this, we can use the jni
implementation by default on arm64 macs. If the user wants to force the
jni implementation for any supported platform, they can opt in with the
`sbt.ipcsocket.jni` system property and/or by setting the serverUseJni
setting.
When the sbt server is running a task, it presents all connected clients
with a message that instructs them that they cancel the running task.
Unfortunately, this often didn't work and the task would keep running
after cancel was entered. The reason for this was because the exec id
passed in to NetworkChannel did not necessarily match the exec id of the
running task. Because cancel in this case is not really exec specific,
this commit adds a flag to NetworkChannel.cancel that forces it to
cancel the running task regardless of what execID is passed in.
In https://github.com/sbt/sbt/pull/5981 I tried to work around the spruious post-macro "a pure expression does nothing" warning (https://github.com/scala/bug/issues/12112) by trying to remove some pure-looking expressions out of the tree.
This quickly backfired when it was reported that sbt 1.4.3 was not evaluating some code. This backs out the macro-level manipulation, and instead try to silence the warning at the reporter level. This feels safer, and it seems to work just as well.
