Ethan Atkins 90dacc339c Support scala 2.13 console in thin client
In order to make the console task work with scala 2.13 and the thin
client, we need to provide a way for the scala repl to use an sbt
provided jline3 terminal instead of the default terminal typically built
by the repl. We also need to put jline 3 higher up in the classloading
hierarchy to ensure that two versions of jline 3 are not loaded (which
makes it impossible to share the sbt terminal with the scala terminal).

One impact of this change is the decoupling of the version of
jline-terminal used by the in process scala console and the version
of jline-terminal specified by the scala version itself. It is possible
to override this by setting the `useScalaReplJLine` flag to true. When
that is set, the scala REPL will run in a fully isolated classloader. That
will ensure that the versions are consistent. It will, however, for sure
break the thin client and may interfere with the embedded shell ui.

As part of this work, I also discovered that jline 3 Terminal.getSize is
very slow. In jline 2, the terminal attributes were automatically cached with a
timeout of, I think, 1 second so it wasn't a big deal to call
Terminal.getAttributes. The getSize method in jline 3 is not cached and
it shells out to run a tty command. This caused a significant
performance regression in sbt because when progress is enabled, we call
Terminal.getSize whenever we log any messages. I added caching of
getSize at the TerminalImpl level to address this. The timeout is 1
second, which seems responsive enough for most use cases. We could also
move the calculation onto a background thread and have it periodically
updated, but that seems like overkill.

Ethan Atkins 525cff7fd7 Use java caffeine library rather than scalacache
sbt depends on scalacache (which hasn't been updated in about a year)
and we really don't need the functionality provided by scalacache. In
fact, the java api is somewhat easier to work with for our use case. The
motivation is that scalacache uses slf4j for logging which meant that it
was implicitly loading log4j. This caused some noisy logs during
shutdown when the previously unused cache was initialized just to be
cleaned up.

This commit also upgrades caffeine and moving forward we can always
upgrade caffeine (and potentially shade it) without any conflict with
the scalacache version.

Eugene Yokota 002f97cae7 Build pipelining
Ref https://github.com/sbt/zinc/pull/744

This implements `ThisBuild / usePipelining`, which configures subproject pipelining available from Zinc 1.4.0.

The basic idea is to start subproject compilation as soon as pickle JARs (early output) becomes available. This is in part enabled by Scala compiler's new flags `-Ypickle-java` and `-Ypickle-write`.

The other part of magic is the use of `Def.promise`:

```
earlyOutputPing := Def.promise[Boolean],
```

This notifies `compileEarly` task, which to the rest of the tasks would look like a normal task but in fact it is promise-blocked. In other words, without calling full `compile` task together, `compileEarly` will never return, forever waiting for the `earlyOutputPing`.

Eugene Yokota f947970247 versionScheme setting + better eviction warning
Ref https://github.com/sbt/sbt/issues/5710
Ref https://github.com/sbt/librarymanagement/pull/339

This adds `versionScheme` setting. When set, it is included into POM, and gets picked up on the other side as an extra attribute of ModuleID. That information in turn is used to inform the eviction warning.

This should reduce the false positives associated with SemVer'ed libraries showing up in the eviction warning.

Ethan Atkins 2ecf5967ee Upgrade LineReader to JLine3
This commit upgrades sbt to using jline3. The advantage to jline3 is
that it has a significantly better tab completion engine that is more
similar to what you get from zsh or fish.

The diff is bigger than I'd hoped because there are a number of
behaviors that are different in jline3 vs jline2 in how the library
consumes input streams and implements various features. I also was
unable to remove jline2 because we need it for older versions of the
scala console to work correctly with the thin client. As a result, the
changes are largely additive.

A good amount of this commit was in adding more protocol so that the
remote client can forward its jline3 terminal information to the server.

There were a number of minor changes that I made that either fixed
outstanding ui bugs from #5620 or regressions due to differences between
jline3 and jline2.

The number one thing that caused problems is that the jline3 LineReader
insists on using a NonBlockingInputStream. The implementation ofo
NonBlockingInputStream seems buggy. Moreover, sbt internally uses a
non blocking input stream for system in so jline is adding non blocking
to an already non blocking stream, which is frustrating.

A long term solution might be to consider insourcing LineReader.java
from jline3 and just adapting it to use an sbt terminal rather than
fighting with the jline3 api. This would also have the advantage of not
conflicting with other versions of jline3. Even if we don't, we may want to
shade jline3 if that is possible.

Ethan Atkins 1b03c9b1a9 Make Terminal a trait to support multiple clients
In order to support a multi-client sbt server ux, we need to factor
`Terminal` out into a class instead of a singleton. Each terminal provides
and outputstream and inputstream. In all of the places where we were
previously relying on the `Terminal` singleton we need to update the
code to use `Terminal.get`, which will redirect io to the terminal whose
command is currently running.

This commit does not implement the server side ui for network clients.
It is just preparatory work for the multi-client ui.

The Terminal implementations have thread safe access to the output
stream. For this reason, I had to remove the sychronization on the
ConsoleOut lockObject. There were code paths that led to deadlock when
synchronizing on the lockObject.

Ethan Atkins 7c31e03d27 Improve supershell appender management
To avoid reliance on jvm global variables, we need to share the super
shell state with each of the console appenders that write to the console
out. We only set the progress state for the console appenders for the
screen. This prevents messages that are below the global logging level
from modifying the progress state without preventing them from being
written to other appenders.

The ability to set the ProgressState for each of the console appenders
is added in a companion util PR.

I verified that the test output of io/test was correctly written to the
streams after this change (there were no progress lines in the output).

Ethan Atkins f7f7addff7 Bump io
This new version of io breaks source and binary compatibility everywhere
that uses the register(path: Path, depth: Int) method that is defined on
a few interfaces because I changed the signature to register(glob:
Glob). I had to convert to using a glob everywhere that register was
called.

I also noticed a number of places where we were calling .asFile on a
file. This is redundant because asFile is an extension method on File
that just returns the underlying file.

Finally, I share the IOSyntax trait from io in AllSyntax. There was more
or less a TODO suggesting this change. The one hairy part is the
existence of the Alternative class. This class has unfortunately somehow
made it into the sbt package object. While I doubt many plugins are
using this, it doesn't seem worth breaking binary compatibility to get
rid of it. The issue is that while Alternative is defined private[sbt],
the alternative method in IOSyntax is public, so I can't get rid of
Alternative without breaking binary compatibility.

I'm not deprecating Alternative for now because the sbtProj still has
xfatal warnings on. I think in many, if not most, cases, the Alternative
class makes the code more confusing as is often the case with custom
operators. The confusion is mitigated if the abstraction is used only in
the file in which it's defined.

I had to turn off -Xfatal-warnings in commandProj because after updating
io, commandProj depends on the deprecated EventMonitor class. In #4335,
I stop using EventMonitor, but deprecate the Watched class which is both
defined and used (as an unused attribute key) in commandProj. I think we
can probably get rid of Watched in 1.4.x and certainly in a hypothetical
2.x, so hopefully we can restore -Xfatal-warnings sooner than later.

I also had to replace uses of IO.classLocationFile with
IO.classLocationPath to avoid compilation failures due to
-Xfatal-warnings.
