This PR adds a possibility to generate native-image for engine-runner. Note that due to on-demand loading of stdlib, programs that make use of it are currently not yet supported (that will be resolved at a later point). The purpose of this PR is only to make sure that we can generate a bare minimum runner because due to lack TruffleBoundaries or misconfiguration in reflection config, this can get broken very easily. To generate a native image simply execute: ``` sbt> engine-runner-native/buildNativeImage ... (wait a few minutes) ``` The executable is called `runner` and can be tested via a simple test that is in the resources. To illustrate the benefits see the timings difference between the non-native and native one: ``` >time built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --no-ir-caches --in-project test/Tests/ --run engine/runner-native/src/test/resources/Factorial.enso 6 720 real 0m4.503s user 0m9.248s sys 0m1.494s > time ./runner --run engine/runner-native/src/test/resources/Factorial.enso 6 720 real 0m0.176s user 0m0.042s sys 0m0.038s ``` # Important Notes Notice that due to a [bug in GraalVM](https://github.com/oracle/graal/issues/4200), which is already fixed in 22.x, and us still being on 21.x for the time being, I had to add a workaround to our sbt build to build a different fat jar for native image. To workaround it I had to exclude sqlite jar. Hence native image task is on `engine-runner-native` and not on `engine-runner`. Will need to add the above command to CI. |
