Fix type coerceion between signed/unsigned types

Originally if a larger unsigned type was added to a smaller signed type,
the result would be casted to the unsigned type instead of a larger
signed type. Now we cast to a larger signed type if necessary.

Apache Daffodil (incubating)

Introduction

Apache Daffodil (incubating) is the open source implementation of the Data Format Description Language (DFDL), a specification created by the Open Grid Forum. DFDL is capable of describing many data formats, including textual and binary, commercial record-oriented, scientific and numeric, modern and legacy, and many industry standards. It leverages XML technology and concepts, using a subset of W3C XML schema type system and annotations to describe such data. Daffodil uses this description to parse data into an infoset represented as XML or JSON, easily capable of ingestion, validation, and transformation.

For more information about Daffodil, see https://daffodil.apache.org/.

Build Requirements

  • JDK 8 or higher
  • SBT 0.13.8 or higher

Getting Started

SBT is the officially supported tool to build Daffodil, run all tests, create packages, and more. Below are some of the more common commands used for Daffodil development.

Note that compiling and running all Daffodil tests works best with at least 6GB of memory, more than is usually provided by default. We recommended that you supply -mem 6144 either as an sbt option (e.g. sbt -mem 6144 test) or edit /etc/sbt/sbtopts to increase the available memory when running the below commands.

Compile

$ sbt compile

Tests

The following command runs all unit tests.

$ sbt test

The following command runs all command line interface tests.

$ sbt it:test

Command Line Interface

The following command creates Linux and Windows shell scripts in daffodil-cli/target/universal/stage/bin/. See the Command Line Interface documentation for details on its usage.

$ sbt daffodil-cli/stage

Apache RAT

This following command generates an Apache RAT report in target/rat.txt and errors if any unapproved licenses are found.

$ sbt ratCheck

Getting Help

For questions, we can be reached at the dev@daffodil.apache.org or user@daffodil.apache.org mailing lists or in #Daffodil on ASF HipChat. Bugs can be reported via the Daffodil JIRA.
