Right now the Standard.Base library needs 153 classes registered for reflection. Libs guys, @radeusgd, @AdRiley, @jdunkerley, @GregoryTravis - isn't that a bit too much?

Registered 153 classes for reflection
There was a problem hiding this comment.
For every registered class, I have to register all its public:
- methods
- constructors
- fields
That may be too much - as not all these methods are really called by Enso code. As such, it might be better to use following pattern. Rather than calling org.w3c.dom.Element.getTagName() you could wrap the call into:
class XML_Utils {
public static String getTagName(Element e) {
return e.getTagName();
}
}that way we would concentrate and select only the needed methods and the transitive closure of needed code computed by native-image would be smaller.
If we don't create the wrapper methods then we'll be forced to polyglot java import additional classes like in 6f3bfad as the native image needs to know types of classes we want to invoke instance methods on.

isn't that a bit too much?
Looking at the list you provided, every of these classes seems needed to provide some of the functionality of the standard library. The std-lib provides a broad variety of functionalities so it seems expected it may have some dependencies. 153 does not seem that large to me.
I guess we may want to discuss whether we should split off some of these dependencies away from Base into separate libraries. I guess we could indeed do so, to keep a 'lighter' "core". IF we split off, I suspect most of our base workflows will for the time being import most of the separated parts anyway, as they are expected to be available for the users out of the box. So what could be the benefit of splitting?
I expect @jdunkerley may have some opinions on whether we want to keep a 'big' Base library or make it more modularized.

We shouldn't be counting just the classes, but rather methods. The problem with current approach is that by using a method rich class like HttpClient we "bring in" all its methods (including for example such a megamorphic methods like equals, hashCode and toString), while we are probably using just a few. The
class XML_Utils {
public static String getTagName(Element e) {
return e.getTagName();
}
}allows us to select only the needed methods and the transitive closure of needed code computed by native-image would be smaller. Hence I'd like you to use this static method wrapper where possible for Standard libraries to be eligible for native image compilation.
Right now the ./runner has 418MB (with Graal.js and GraalPython compiled in). By carefully selecting what goes into the image we might get to 410MB or maybe even below 400MB.

That's like 5%? Seems like a lot of hassle and maintenance for reducing the image by that amount.

Yes, it is not going to be much.

On contrary, I see that (e.g. exactly specifying what methods are used) as a good coding and architecture practice regardless of the expected gain in the size of native executable. Way more responsible than importing everything and hoping someone makes the result efficient.
If this native compilation of libraries gets to production, we should make sure we squeeze Standard libraries to make them as much effective as possible.

We have a failure in generated tests: I wonder how to run those tests locally, @kazcw? Meanwhile 8ab9362 is made as a blind shot fix. Btw. I have found java-tests comment, but that is giving me the non-interesting suggestion - e.g. how to run Java part. There is no note about running the Rust part! Update, it is probably: enso/lib/rust/parser/generate-java$ cargo run --bin java-tests > GeneratedFormatTests.java |

Looks good generally. I am not entirely satisfied with how the classes inside polyglot directories of libraries/projects are looked up, but I guess you are neither. As I said in one of my review comments, without the dependency on runtime, I cannot think of a more elegant way how to query std library for its polyglot directory content.

Minor comment - I didn't know about |
Native image can do various tricks. Here is another thing to explore: |
Pull Request Description
The goal of this PR is to execute
./runner --run test/Base_Tests ^Text. That requires us to properly register allpolyglot java importclasses for reflective access. That's done viaEnsoLibraryFeature- a code that gets executed duringnative-imagebuild. The feature finds all libraries with JARs on classpath, parses all their sources, finds all their imported Java classes and reports them via native image API as eligible for reflection.Checklist
Please ensure that the following checklist has been satisfied before submitting the PR:
