The existing .travis.yml in the util project runs:
mimaReportBinaryIssues
scalafmtCheckAll
whitesourceCheckPolicies
test
The first three are already handled by the first build in the matrix. I
add the util tests to the first jdk11 build and the jdk8 build.
Closing the ManagedClassLoader generated by test can cause nonlocal
effects because the jdk shares some JarFile resources across multiple
URLClassLoaders. As a result, if one classloader is trying to load a
resource and the classloader is closed, it might cause the resource
loading to fail (see https://github.com/sbt/sbt/issues/5262). This can
be fixed by moving the scalatest framework jar (and its dependencies)
into an additional classloader layer that sits between the scala library
loader and the rest of the test dependencies.
In addition to adding the new layer, I reworked the
ReverseLookupClassLoader to use its dependent classloader to find
resources that may below it in the classloading hierarchy rather than
constructing an entirely new classloader for resources.
After this change, I was able to run test in the repro project:
https://github.com/rjmac/sbt-5262 1000 times with no failures. Note that
the repro is sensitive to the jdk used. I could not reproduce with jdk11
but I could typically induce a failure within 20 or so runs with jdk8.
I benchmarked this change with
https://github.com/eatkins/scala-build-watch-performance and performance
was roughly the same as 1.3.4 with turbo mode and about 200-250ms faster
in non-turbo mode (which can be explained by the time to load the
scalatest classes).
This makes it possible to do mkIvyConfiguration.value.withXXX(...) for
all the methods in InlineIvyConfiguration. (I need this to remove
inter-project resolvers when fetching dotty from sbt-dotty to avoid
accidentally fetching a local project in the build of dotty itself).
The previous implementation of ZombieClassLoader was not thread safe.
This caused problems because it is possible for the ManagedClassLoader
in test to leak into the coursier thread pool if the test uses bouncy
castle apis. Unfortunately, these apis seem to in some cases assign
static variables using the Thread context class loader. Because the
bouncycastle apis are implemented by the jdk, they are found in the
system classloader and thus the static references leak out of the test
context.
I had a local repro of https://github.com/sbt/sbt/issues/5249 that is
fixed by this change.
I found it hard to reason about where certain local variables, like
currentRef, were coming from. I also changed 'x' to 'extracted' in a few
places for clarity as well.
Rather than putting the background job temporary files in whatever
java.io.tmpdir points to, this commit moves the files into a
subdirectory of target in the project root directory.
To make the directory configurable via settings, I had to move the
declaration of the bgJobService setting later in the project
initialization process. I don't think this should matter because
background jobs shouldn't be created until after the project has loaded
all of its settings..
When a user calls sbt exit and there is an active background job, sbt
may not exit cleanly. This was primarily because the
background job service shutdown method depended on the
StandardMain.executionContext which was closed before the background job
service was shutdown. This was fixable by reordering the resource
closing in StandardMain.runManaged.
When running a main method, if the user inputs ctrl+c then the `run`
task will exit but the main method is not interrupted so it continues
running even once sbt has returned to the shell. If the main method is a
webserver, this prevents run from ever starting again on a fixed port.
To fix this, we can modify the waitForTry method to stop the job if an
exception is thrown (ctrl+c leads to an interrupted exception being
thrown by waitFor).
I rework the BackgroundJobService so that the default implementation of
waitForTry is now usable and no longer needs to be overridden. The side
effect of this change is that waitFor may now throw an exception. Within
sbt, waitFor was only used in one place and I reworked it to use
waitForTry instead. This could theoretically break a downstream user who
relied on waitFor not throwing an exception but I suspect that there
aren't many users of this api, if any at all.
The StateTransform class introduced in
9cdeb7120e did not cleanly integrate with
logic for transforming the state using the `transformState` task
attribute. For one thing, the state transform was only applied if the
root node returned StateTransform but no transformation would occur if a
task had a dependency that returned StateTransform. Moreover, the
transformation would override all other transformations that may have
occurred during task evaluation.
This commit updates StateTransform to act very similarly to the
transformState attribute. Instead of wrapping a `State` instance, it now
wraps a transformation function from `State => State`. This function
can be applied on top of or prior to the other transformations via the
`transformState`.
For binary compatibility with 1.3.0, I had to add the stateProxy
function as a constructor parameter in order to implement the `state`
method. The proxy function will generally throw an exception unless the
legacy api is used. To avoid that, I private[sbt]'d the legacy api so
that binary compatibility is preserved but any builds targeting > 1.4.x
will be required to use the new api.
Unfortunately I couldn't private[sbt] StateTransform.apply(state: State)
because mima interpreted it as a method type change becuase I added
StateTransform.apply(transform: State => State). This may be a mima bug
given that StateTransform.apply(state: State) would be jvm public even
when private[sbt], but I figured it was quite unlikely that any users
were using this method anyway since it was incorrectly implemented in
1.3.0 to return `state` instead of `new StateTransform(state)`.
The linting can take a while for large projects because `Def.compiled`
scales in the number of settings. Even for small projects (i.e. scripted
tests), it takes about 50 ms on my computer. This doesn't change the
current behavior because the default value is true.
This can be very noisy, especially for tests that are marked pending
because they fail to load the build. These induce a lengthy and largely
unhelpful "Reload for batch scripted failed..." error message.
This PR includes the values of the `description` and `homepage`
settings into the `ivy.xml` files generated by the `makeIvyXml`
task. It restores the behaviour of sbt 1.2.8 and if `useCoursier`
is set to `false`.
Two things are changed in this PR:
* `IvyXml.content` now adds the `homepage` attribute to the
`description` element if `project.info.homePage` is not empty.
* `CoursierInputsTasks.coursierProject0` now fills the previous
empty `CProject.info` field with the description and homepage.
Closes: #5234
Ref #4211Fixes#4395Fixes#4600
This is a reimplementation of `--addPluginSbtFile`. #4211 implemented the command to load extra `*.sbt` files as part of the global plugin subproject. That had the unwanted side effects of not working when `.sbt/1.0/plugins` directory does not exist. This changes the strategy to load the `*.sbt` files as part of the meta build.
