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
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.
* AutoImport trait is subsumed by def autoImport method under
AutoPlugin class.
* When def autoImport is overridden by a lazy val or a val, *.sbt
automatically imports autoImport._.
This allows plugins to define a Plugins instance that captures both the
plugin and its required dependencies.
Also fixed up some scaladocs that were wrong.
* packageArtifacts is not cleared by defautlSettings
* Added a test for this behavior (this one test should ensure the ordering for most settings is correct.)
Fixes#1176
We cannot break existing users, but we can deprecate the improper usage.
This is part #2 of the workaround for #1156. This ensures that
users will stop using the legacy methods after 0.13.2 is out.
AddSettings should only expose coarse-grained features of AutoPlugins
or else the Logic we use to ensure safe addition completely breaks
down. Leaving it in the code as an escape hatch if we get desparate,
but we need an alternative for controlling ordering later.
* GlobalPlugin has defaults for controlling parallelism on tasks, basic command stuff.
* IvyModule has the configuration for resolving/publishing modules to ivy, assuming
each project is a single module.
* JvmModule has the configuration for compiling/running/testing/packaging Java/Scala
projects.
* Add new AutoPlugins type to AddSettings.
* Ensure any Plugins filter doesn't just automatically always add
autoplugins every time.
* Load.scala can now adjust AutoPlugins ordering
Note: Adjusting autoplugin ordering is dangerous BUT doing a glob
of "put autoplugin settings here" is generally ok.
* remove the notion of Natures from Autoplugins.
* Update tests to use AutoPlugins with no selection for inclusion.
* Rename exisitng Natures code to Plugins/PluginsDebug.
Fixes#1155.
It seems that somehow during the 0.13.{1 -> 2 } transition, we
stopped pointing at the correct key for TaskKeys (either that or
task streams are now all associated with the `streams` key). I
think this may have been inadvertently caused from several
refactorings to enable greater control over the execution of tasks.
This points the `last*` methods at the correct key for tasks,
fixing both `last <key>` and `export <key>` commands.
In 2.11, the implicit version is named `$conforms` so as to avoid
accidental shadowing by user code, which renders methods using
views and subtype bounds inexplicable unusable.
But, SBT intentionally needs to hide it to make the implicits
in this file line up.
This commit opts-in the the required identifiers from Predef,
rather than opting out of conforms. This makes the same code
source compatible with 2.10 and 2.11.
* 'plugins' displays the list of plugins available for each build along with the project IDs each is enabled on
* 'plugin <name>' displays information about a specific plugin in the context of the current project
- if the plugin is activated on the current project and if so, information about the keys/configurations it provides
- how the plugin could be activated if possible
* tries to detect when it is run on an aggregating project and adjusts accordingly
- indicates if an aggregated project has the plugin activated
- indicates to change to the specific project to get the right context
This is a rough implementation and needs lots of polishing and deduplicating.
The help for the commands needs to be added/expanded.
* Can provide suggestions for how to define a plugin given a context (a loaded Project in practice).
* When a user requests an undefined key at the command line, can indicate whether any (deactivated) plugins provide the key.
TODO:
* Hook up to the key parser
* Implement 'help <plugin>'
* Determine how to best provide the context (the current project is often an aggregating root, which is not typically a useful context)
This commit makes the code source compatible across Scala 2.10.3
and https://github.com/scala/scala/pull/3452, which is proposed
for inclusion in Scala 2.11.0-RC1.
We only strictly need the incremental compiler to build on Scala
2.11, as that is integrated into the IDE. But we gain valuable
insight into compiler regressions by building *all* of SBT with
2.11.
We only got there recently (the 0.13 branch of SBT now fully cross
compiles with 2.10.3 and 2.11.0-SNAPSHOT), and this aims to keep
things that way.
Once 2.10 support is dropped, SBT macros will be able to exploit
the new reflection APIs in 2.11 to avoid the need for casting
to compiler internals, which aren't governed by binary compatibility.
This has been prototyped by @xeno-by: https://github.com/sbt/sbt/pull/1121
