* Report completion of a target together with failed actionsGravatar Klaus Aehlig2016-10-27
| | | | | | | | | | | | | | | | Report the completion of all targets together with the root causes on the build event stream. To do so, have TargetCompleteEvent and ActionExecutedEvent be instances of BuildEvent; however, ignore an ActionExecutedEvent in the BuildEventStreamer if the execution was successful. By this change we get, for the first time, a build event stream that is naturally closed, i.e., without Aborted events closing up lose ends. Add a test asserting this property. -- Change-Id: Ie90dd52ee80deb0fdabdce1da551935522880a1a Reviewed-on: https://bazel-review.googlesource.com/#/c/6279 MOS_MIGRATED_REVID=137273002
* Add a new concept of failure causesGravatar Klaus Aehlig2016-10-25
Not all possible reasons for failure are uniquely identified by a label. Therefore, add a new data type describing possible root causes of failures and use it. The new type is added in causes/*.java and coresponds to Haskell's one-line definition data Cause = LabelCause Label | ActionCause Path Label deriving Show With future clean up of other failure causes inadequately described by a label, we expect that type to be extended by new constructors (i.e., new classes implementing Cause). -- Change-Id: I6fec74c78cec6abb9c10e32743b05a792888fead Reviewed-on: https://bazel-review.googlesource.com/#/c/6617 MOS_MIGRATED_REVID=137156390
