build_runner_core 0.3.0

Core tools to write binaries that run builders.

0.3.0

Breaking Changes

• Implementations of BuildEnvironment must now implement the finalizeBuild method. There is a default implementation if you extend BuildEnvironment that is a no-op.
  • This method is invoked at the end of the build that allows you to do arbitrary additional work, such as creating merged output directories.
• The assumeTty argument on IOEnvironment has moved to a named argument since null is an accepted value.
• The outputMap field on BuildOptions has moved to the IOEnvironment class.

New Features/Updates

• Added a outputSymlinksOnly option to IOEnvironment constructor, that causes the merged output directories to contain only symlinks, which is much faster than copying files.
• Added the FinalizedAssetView class which provides a list of all available assets to the BuildEnvironment during the build finalization phase.
  • outputMap has moved from BuildOptions to this constructor, as a named argument.
• The OverridableEnvironment now supports overriding the new finalizeBuild api.
• The number of concurrent actions per phase is now limited (currently to 16), which should help with memory and cpu usage for large builds.

0.2.2+2

• Support package:json_annotation v1.

0.2.2+1

• Tag errors from cached actions when they are printed.

0.2.2

• Changed the default file caching logic to use an LRU cache.

0.2.1+2

• Clarify wording for conflicting output directory options. No behavioral differences.
• Reduce the memory consumption required to create an output dir significantly.
• Increased the upper bound for the sdk to <3.0.0.

0.2.1+1

• Allow reuse cache between machines with different OS

0.2.1

• The hash dir for the asset graph under .dart_tool/build is now based on a relative path to the build script instead of the absolute path.
  • This enables .dart_tool/build directories to be reused across different computers and directories for the same project.

0.2.0

New Features

• The BuildPerformance class is now serializable, it has a fromJson constructor and a toJson instance method.
• Added BuildOptions.logPerformanceDir, performance logs will be continuously written to that directory if provided.
• Added support for global_options in build.yaml of the root package.
• Allow overriding the default Resolvers implementation.
• Allows building with symlinked files. Note that changes to the linked files will not trigger rebuilds in watch or serve mode.

Breaking changes

• BuildPhasePerformance.action has been replaced with BuildPhasePerformance.builderKeys.
• BuilderActionPerformance.builder has been replaced with BuilderActionPerformance.builderKey.
• BuildResult no longer has an exception or stackTrace field.
• Dropped failOnSevere arguments. Severe logs are always considered failing.

Internal changes

• Remove dependency on package:cli_util.

0.1.0

Initial release, migrating the core functionality of package:build_runner to this package.
