Every time that the compile task is run, there are potentially a large
number of iops that must occur in order for sbt to generate the source
file list as well as for zinc to check which files have changed since
the last build. This can lead to a noticeable delay between when a build
is started (either manually or by triggered execution) and when
compilation actually begins. To reduce this latency, I am adding a
global view of the file system that will be stored in
BasicKeys.globalFileTreeView.
To make this work, I introduce the StampedFile trait, which augments the
java.io.File class with a stamp method that returns the zinc stamp for
the file. For source files, this will be a hash of the file, while for
binaries, it is just the last modified time. In order to gain access to
the sbt.internal.inc.Stamper class, I had to append addSbtZinc to the
commandProj configurations.
This view may or may not use an in-memory cache of the file system tree
to return the results. Because there is always the risk of the cache
getting out of sync with the actual file system, I both make it optional
to use a cache and provide a mechanism for flushing the cache. Moreover,
the in-memory cache implementation in sbt.io, which is backed by a
swoval FileTreeRepository, has the property that touching a monitored
directory invalidates the entire directory within the cache, so the
flush command isn't even strictly needed in general.
Because caching is optional, the global is of a FileTreeDataView, which
doesn't specify a caching strategy. Subsequent commits will make use of
this to potentially speed up incremental compilation by caching the
Stamps of the source files so that zinc does not need to compute the
hashes itself and will allow for continuous builds to use the cache to
monitor events instead of creating a new, standalone FileEventMonitor.
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.

This introduces a new subproject named scripted-sbt-redux. The purpose of this new subproject is to workaround the 'sbt.test` package vs `Keys.test` key confusion (#4242) while maintaining the forward compatibility of 0.13.17's sbt cross testing ^^ (#4241).
The new subproject uses `sbt.scriptedtest` package name, and that's the one that will be used by the mothership.
Meanwhile "scripted-sbt" subproject will also be published for compatibility purpose.
This hot path was discovered by retronym using FlameGraph.
This removes intermediate creation of Array.
`filesModifiedBytes` in particular was bad as it was going through all `*.class` files, each generating an Array. This replaces that with `fileModifiedHash` that accepts `MessageDigest`.
According to the flamegraph, evalCommon footprint reduced from 4.5% to 3.6%.
Using `time sbt reload reload reload exit`, the median reduced from 41.450s to 39.467s.
previously I was using separate thread in a forked test to test the server, but that is not enough isolation to run multiple server tests.
This adds `RunFromSourceMain.fork(workingDirectory: File)`, which allows us to run a fresh sbt on the given working directory. Next, I've refactored the stateful client-side buffer to a class `TestServer`.
* 1.1.x:
Use Java's redirectInput rather than sys.process's connectInput
Re-write toolboxClasspath to use sbt-buildinfo
Cleanup generateToolboxClasspath
Upgrade to sbt-buildinfo 0.8.0
Fix how fullClasspath is defined in TestBuildInfo
delete buildinfo.BuildInfo from sbt main
Conflicts:
project/plugins.sbt
* 1.1.x:
Update mimaPreviousArtifacts/sbt.version
Introduce SBT_GLOBAL_SERVER_DIR env var to override too long paths
Handle very long socket file paths on UNIX
Conflicts:
project/build.properties
This works around the name conflict between sbt.test package and sbt.Keys.test.
1. sbt.test package is renamed to sbt.scriptedtest. This allows 1.0 plugins and builds to use `test` to mean `Keys.test`.
2. To keep binary compatibility for sbt 0.13 scripted, I am adding `sbt.test.ScriptedRunner` and `sbt.test.ScriptedTests` in `scripted-plugin` artifact.
3. Another affected user is Giter8 plugin that uses ScriptedPlugin. Since the intereactions are limited to `sbt.ScriptedPlugin.*`, we should be fine here. - https://github.com/foundweekends/giter8/blob/v0.11.0-M2/plugin/src/main/scala-sbt-1.0/giter8/SBTCompat.scala
Fixes#3538
This brings in `sbt.ScriptedPlugin` as `sbt.plugins.ScriptedPlugin` into sbt mothership.
In addition, `sbt.plugins.SbtPlugin` is added that enables the scripted plugin and `sbtPlugin := true`.
This allows plugin authors to bring in scripted plugin by writing:
```scala
lazy val root = (project in file("."))
.enablePlugins(SbtPlugin)
```
This is what it looks like now! 🎉

Previously I was seeing the error upon the first scripted test. I thought it was because Main was somehow not early enough. It might just be because scripted technically runs as part of the build.
Ref sbt/io#110
This is an implementation of `textDocument/definition` request.
Supports types only, and only in case when type is found in Zinc Analysis. When source(s) are found then editor opens potential source(s).
This simple implementation does not use semantic data.
During the processing of `textDocument/didSave`, we will start collecting the location of Analysis files via `lspCollectAnalyses`.
Later on, when the user asked for `textDocument/definition`, sbt server will invoke a Future call to lspDefinition, which direct reads the files to locate the definition of a class.
In addition to TCP, this adds sbt server support for IPC (interprocess communication) using Unix domain socket and Windows named pipe.
The use of Unix domain socket has performance and security benefits.
