When running in parallel mode, worker processes forward errors thrown during task processing to the master process, which in turn exits with an error. However, there are cases where the error is not directly related to processing the entry-point. One such case is when there is not enough memory (for example, due to all the other tasks being processed simultaneously). Previously, an `ENOMEM` error thrown on a worker process would propagate to the master process, eventually causing ngcc to exit with an error. Example failure: https://circleci.com/gh/angular/angular/682198 This commit improves handling of these low-memory situations by detecting `ENOMEM` errors and killing the worker process, thus allowing the master process to decide how to handle that. The master process will put the task back into the tasks queue and continue processing tasks with the rest of the worker processes (and thus with lower memory pressure). PR Close #36626 |
