This adds a new setting `enableConsistentCompileAnalysis`,
which enables the new "Consistent" Analysis format,
which is faster and more repeatable than the status quo.
This is initialized to `true` by default.
It can be opted out either by the setting or using
`-Dsbt.analysis2024=false`.
**Problem**
Plugins are topologically sorted, but plugins with equal weigh could
modify the same key via `~=` etc, resulting in different builds
depending on the artifact.
**Solution**
This attempts to fix that by first sorting the selected plugins
by the class name before sorting it topologically.

Problem
-------
sbtn 1.8.1 was built using ubuntu-latest, which meant picking up newer
glibc.
Solution
--------
This downgraded the ubuntu machine to build sbtn.
Migrates TreeView.scala to use Contraband from scala.util.parsing.json,
because this is now deprecated.
The TreeView logic is used in the dependencyBrowseTree task.
Since build.sbt is compiled/evaluated in `sbt.compiler.Eval`,
this commit introduces a `BuildServerEvalReporter` to redirect
the compiler errors to the BSP clients.
A new `finalReport` method is added in the new `EvalReporter` base class
to reset the old diagnostics.
* Refactor so as to be testable
* Queue stores the _beginning_ timestamp of each GC time delta
* Message states the correct time over which the GC time was recorded
* Add heap stats from java.lang.Runtime to the message
This test works fine locally on all platforms but there are issues in
CI. I think that it might work ok with 1.4.2 without a lot of extra
effort so I'm going to disable it for now.
This commit adds a wizard for installing sbtn along with tab completions
for bash, fish, powershell and zsh. It introduces the `installSbtn`
command which installs sbtn into ~/.sbt/1.0/bin/sbtn(.exe) depending on
the platform. It also can optionally install completions. The
completions are installed into ~/.sbt/1.0/completions. The sbtn native
executable is installed by downloading the sbt universal zip for the
version (which can be provided as an input argument with a fallback to
the running sbt version) and extracting the platform specific binary
into ~/.sbt/1.0/bin. After installing the executable, it offers to setup
the path and completions for the four shells. With the user's consent,
it adds a line to the shell config that updates the path to include
~/.sbt/1.0/bin and another line to source the appropriate completion
file for the shell from ~/.sbt/1.0/completions.
It can be useful for plugin and build authors to have access to some of
the virtual terminal properties. For instance, when writing a task that
needs a password, the author may wish to put the terminal in raw mode
with echo disabled. This commit introduces a new Terminal trait at the
sbt level and a corresponding task, terminal, that provides a basic
terminal api. The Terminal returned by the terminal task will correspond
to the terminal that initiated the task so that it should work with sbtn
as well as in console mode.
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.
The continuous command recompiles the setting graph into a CompiledMap
data structure so that it can determine which files it needs to
transitively monitor during watch. Generating the CompiledMap can be
very slow for large projects (5 seconds or so on my computer in the sbt
project) and this startup cost is paid every time the user enters a
watch with `~`. To avoid this, we can cache the compile map that is
generated during the initial settings evaluation.
The only real drawback I can see is that the compiled map is guaranteed
to remain in memory so long as the BuildStructure instance that holds it
is alive. Given the performance benefit, this seems like a worthwhile
tradeoff.
The existing implementation of watch did not work with the thin client.
In sbt 1.3.0, watch was changed to be a blocking command that performed
manual task evaluation. This commit makes the implementation more
similar to < 1.3.0 where watch modifies the state and after running the
user specified command(s), it enters a blocking command. The new
blocking command is very similar to the shell command.
As part of this change, I also reworked some of the internals of watch
so that a number of threads are spawned for reading file and input
events. By using background threads that write to a single event queue,
we are able to block on the file events and terminal input stream rather
than polling. After this change, the cpu utilization as measured by ps
drops from roughly 2% of a cpu to 0.
To integrate with the network client, we introduce a new UITask that is
similar to the AskUserTask but instead of reading lines and adding execs
to the command queue, it reads characters and converts them into watch
commands that we also append to the command queue.
With this new implementation, the watch task that was added in 1.3.0 no
longer works. My guess is that no one was really using it. It wasn't
documented anywhere. The motivation for the task implementation was that
it could be called within another task which would let users define a
task that monitors for file changes before running. Since this had never
been advertised and is only of limited utility anyway, I think it's fine
to break it.
I also had to disable the input-parser and symlinks tests. I'm not 100%
sure why the symlinks test was failing. It would tend to work on my
machine but fail in CI. I gave up on debugging it. The input-parser test
also fails but would be a good candidate to be moved to the client test
in the serverTestProj. At any rate, it was testing a code path that was
only exercised if the user changed the watchInputStream method which is
highly unlikely to have been done in any user builds.
The WatchSpec had become a nuisance and wasn't really preventing from
any regressions so I removed it. The scripted tests are how we test
watch.
This commit makes it possible for the sbt server to render the same ui
to multiple clients. The network client ui should look nearly identical
to the console ui except for the log messages about the experimental
client.
The way that it works is that it associates a ui thread with each
terminal. Whenever a command starts or completes, callbacks are invoked
on the various channels to update their ui state. For example, if there
are two clients and one of them runs compile, then the prompt is changed
from AskUser to Running for the terminal that initiated the command
while the other client remains in the AskUser state. Whenever the client
changes uses ui states, the existing thread is terminated if it is
running and a new thread is begun.
The UITask formalizes this process. It is based on the AskUser class
from older versions of sbt. In fact, there is an AskUserTask which is
very similar. It uses jline to read input from the terminal (which could
be a network terminal). When it gets a line, it submits it to the
CommandExchange and exits. Once the next command is run (which may or
may not be the command it submitted), the ui state will be reset.
The debug, info, warn and error commands should work with the multi
client ui. When run, they set the log level globally, not just for the
client that set the level.

It seems like some tests are using `ClassLoader#getResource("")` to acquire the `classes` directory path. This does not seem to work on sbt 1.3.6, which returns `file:/home/travis/.cache/coursier/v1/https/repo1.maven.org/maven2/org/apache/logging/log4j/log4j-api/2.11.2/log4j-api-2.11.2.jar!/META-INF/versions/9/`. To workaround this issue, I've switched to loading the known folder name instead.
I realized it was probably not ideal to have these implicit JsonFormats
defined directly in the FileStamp object because they might
inadvertently be brought into scope with a wildcard import.
This commit adds a new ClassLoaderCache that builds on the
ClassLoaderCache that is present in zinc (and can be used to build an
instance of the zinc ClassLoaderCache to preserve compatibility). It
differs from the zinc classloader cache that it does not use direct
SoftReferences to classloaders. Instead, we create a wrapper loader
that can't load any classes and just delegates to its parent. This
allows us to add a thread that reaps the soft reference to the wrapper
loader. Crucially, we add a custom SoftReference class that has a strong
reference to the underlying classloader. This allows us to call close on
the strong reference.
The one issue with this approach is that we can't
rescue the jvm from crashing with an OOM: metaspace because the jvm
doesn't give us a chance to close and dereference the underlying
classloaders before it crashes. It WILL collect classloaders under
normal memory pressure, just not metaspace pressure. To fix this, I
check if the MaxMetaspaceSize is set via an MxBean and, if it is, we
fill the cache with regular soft references. We are going to change the
bash script to not set -XX:MaxMetaspaceSize by default so most builds
should probably end up correctly closing the classloaders after this
change. But we should break existing builds that set MaxMetaspaceSize
but don't crash.
As part of this commit, I audited all of the places where we were
instantiating ClassLoaderCache instances and instead pass in the
state's ClassLoaderCache instance. This reduces the total number of
classloaders created.
Previously the persistent attribute map was only reset when the file
event monitor detected a change. This made it possible for the cache to
be inconsistent with the state of the file system*. To fix this, I add an
observer on the file tree repository used by the continuous build that
invalidates the cache entry for any path for which it detects a change.
Invalidating the cache does not stamp the file. That only happens either
when a task asks for the stamp for that file or when the file event
monitor reports an event and we must check if the file was updated or
not.
After this change, touching a source file will not trigger a build
unless the contents of the file actually changes.
I added a test that touches one source file in a project and updates the
content of the other. If the source file that is only ever touched ever
triggers a build, then the test fails.
* This could lead to under-compilation because ExternalHooks would not
detect that the file had been updated.
The new io verion removes the PathFinder <-> Glob implicit translations.
It also has a number of small bug fixes related to directory listing via
FileTreeView.
