Within buildPluginDefinition(), the call to setProject() can
(and usually will) return a modified structure together with
the new state.
The subsequent call to evalPluginDef() should use the updated
structure, rather the old stucture that was present before
the setProject() ("pluginDef"); if that is not the case,
the code called by evalPluginDef() will find an inconsistent
structure/state combination, and behave in bizarre ways as
a result.
More in general, it is a bit dangerous to pass to routines
in parallel the two separate state and structure, as the
two may easily inadvertently fall out of alignment, as in this
case.
This patch should be applied to both the 0.13 branch as well
as to a future 0.12.5 release (the corresponding file there
is ./main/Load.scala).
It turns out windows blocks until a process is finished when
you try to close the stderr handle, but not stdout. Therefore,
we leave stderr open when we shut down, which lets the server
continue to run on windows.
Add logging of various operations the transactional class file manager is
doing. You can pass logger to be used by the transactional class file
manager by using overloaded definition of `ClassfileManager.transactional`
method. The old overload has been deprecated.
The factory methods for class file manager in IncOptions companion object
has been deprecated in favor of using ClassfileManager companion object
directly. The code in Defaults.scala has been updated to use non-deprecated
methods. The logging is turned off by default.
The canonical way of enabling transactional class file manager in sbt
project is:
```
incOptions := incOptions.value.withNewClassfileManager(
sbt.inc.ClassfileManager.transactional(
crossTarget.value / "classes.bak",
(streams in (compile, Compile)).value.log
)
)
```
It's a bit verbose which shows that the api for this is not the best.
However, I don't expect sbt users to need this code very often.
This patch should help debug the problem described in #1184
It should have been there from the beginning because NameHashing is tied
to internals of the API subproject.
It was added to incremental subproject by mistake.
The deprecated method should forward to the other overloaded alternative
but it recursed instead.
This kind of mistake would be easily caught by linter warning about
unused `newConfig` local variable. I hope we'll get there some day.
Fixes#1251
`DefaultOptions.addResolvers` and `DefaultOptions.addPluginResolvers`
should not reset the existing value while adding the new ones. The
names are prefixed with _add_ afterall.

1) When `test` is run and there are no tests available, omit logging output.
Especially useful for aggregate modules. `test-only` et al unaffected. (#1185)
2) Added a new setting `testResultLogger` to allow customisation of logging of test results.
* Expose new EvaluateTaskConfig throughout all the APIs
* Create a key for cancellation configuration
* Add default values for cancellation in GlobalPlugin
* Create a test to ensure that cancellation can cancel tasks.
* Deprecate all the existing mechanisms of evaluating tasks which
use the EvaluateConfig API.
* Create a new EvaluateTaskConfig which gives us a bit more freedom
over changign config options to EvaluateTask in the future.
* Create adapted from old EvaluateTask to new EvaluateTask
* Add hooks into signals class to register/remote a signal listener
directly, rather than in an "arm" block.
* Create TaskEvaluationCancelHandler to control the strategy of
who/whom can cancel (sbt-server vs. sbt-terminal).
* Create a null-object for the "can't cancel" scenario so the
code path is exactly the same.
This commit does not wire settings into the build yet, nor does it
fix the config extractio methods.
It has been reported in sbt/sbt#1237 that stack overflows may occur during the
extraction of used names (and later of dependencies between files). This
problem has been introduced by sbt/sbt#1163, which was about recording the
dependencies of macro arguments.
When a macro is expanded, the compiler attaches the tree before expansion to
the tree representing the expanded macro. As of Scala 2.11-RC3, some macros
have themselves attached as original tree, which caused the same macro to be
inspected over and over until a stack overflow.
This commit solves this problem by making sure that the original of a macro
expansion will be inspected if and only if it is different from the expanded
tree.
Fixessbt/sbt#1237
Add two scripted tests that illustrate a problem occurring with Scala 2.11-RC3
where some macros have themselves attached as original tree, which causes a
stack overflow during dependency extraction.
* sbt 0.12.3 introduced sbt/sbt@482f99 to fix#637 and #641.
* The underlying issue of #641 was an incorrect classifier, and it was
fixed in sbt/sbt@718fa9 for #683 and shipped as sbt 0.13.0.
