# Important Notes
- After this PR, one can theoretically run enso with any JRE with version at least 21.
- Removed `sbt bootstrap` hack and all the other build time related hacks related to the handling of GraalVM distribution.
- `project-manager` remains backward compatible - it can open older engines with runtimes. New engines now do no longer require a separate runtime to be downloaded.
- sbt does not support compilation of `module-info.java` files in mixed projects - https://github.com/sbt/sbt/issues/3368
- Which means that we can have `module-info.java` files only for Java-only projects.
- Anyway, we need just a single `module-info.class` in the resulting `runtime.jar` fat jar.
- `runtime.jar` is assembled in `runtime-with-instruments` with a custom merge strategy (`sbt-assembly` plugin). Caching is disabled for custom merge strategies, which means that re-assembly of `runtime.jar` will be more frequent.
- Engine distribution contains multiple JAR archives (modules) in `component` directory, along with `runner/runner.jar` that is hidden inside a nested directory.
- The new entry point to the engine runner is [EngineRunnerBootLoader](https://github.com/enso-org/enso/pull/7991/files#diff-9ab172d0566c18456472aeb95c4345f47e2db3965e77e29c11694d3a9333a2aa) that contains a custom ClassLoader - to make sure that everything that does not have to be loaded from a module is loaded from `runner.jar`, which is not a module.
- The new command line for launching the engine runner is in [distribution/bin/enso](https://github.com/enso-org/enso/pull/7991/files#diff-0b66983403b2c329febc7381cd23d45871d4d555ce98dd040d4d1e879c8f3725)
- [Newest version of Frgaal](https://repo1.maven.org/maven2/org/frgaal/compiler/20.0.1/) (20.0.1) does not recognize `--source 21` option, only `--source 20`.
close#7871close#7698
Changelog:
- fix: the `run` script logic to place the GraalVM runtime in the expected directory when building the bundle
- fix: the `makeBundles` SBT logic to place the GraalVM runtime in the expected directory
While looking into #7698 discovered that the `buildGraalDistribution`
task would fail to use the old (pre-23.0) GraalVM naming of artifacts.
This has changed since #7176.
The fix does not attempt to fix a problem of packaged GraalVM name in
`runtime`. That, as the ticket mentiones it, is the role of rust build
script that creates the correct bundle.
Follow-up of recent GraalVM update #7176 that fixes downloading of GraalVM for Mac - instead of "darwin", the releases are now named "macos"
# Important Notes
Also re-enables the JDK/GraalVM version check as onLoad hook to the `sbt` process. We used to have that check a long time ago. Provides errors like this one if the `sbt` is run with a different JVM version:
```
[error] GraalVM version mismatch - you are running Oracle GraalVM 20.0.1+9.1 but GraalVM 17.0.7 is expected.
[error] GraalVM version check failed.
```
The current instructions to _build, use and debug_ `project-manager` and its engine/ls process are complicated and require a lot of symlinks to properly point to each other. This pull requests simplifies all of that by introduction of `ENSO_ENGINE_PATH` and `ENSO_JVM_PATH` environment variables. Then it hides all the complexity behind a simple _sbt command_: `runProjectManagerDistribution --debug`.
# Important Notes
I decided to tackle this problem as I have three repositories with different branches of Enso and switching between them requires me to mangle the symlinks. I hope I will not need to do that anymore with the introduction of the `runProjectManagerDistribution` command.
`--compile` command would run the compilation pipeline but silently omit any encountered errors, thus skipping the serialization. This maybe was a good idea in the past but it was problematic now that we generate indexes on build time.
This resulted in rather obscure errors (#6092) for modules that were missing their caches.
The change should significantly improve developers' experience when working on stdlib.
# Important Notes
Making compilation more resilient to sudden cache misses is a separate item to be worked on.
The change adds support for generating suggestions and bindings when using the convenient task for building individual stdlib components. By default commands do not generate index since it adds build time. But `buildStdLibAllWithIndex` will.
Closes#5999.
Treat `Boolean.False` and `Boolean.True` as the corresponding primitives. Now, `Boolean.False == False` returns true.
# Important Notes
`False` and `True` constructs, that are converted to `ConstructorNode` during Truffle codegen, are handled specially in `ConstructorNode`. The easiest fix was to implement a similar special handling in `QualifiedAccessorNode`, although not the cleanest one.
A better solution would be to provide transformation of `Boolean.True` IR to a true literal in `ApplicationSaturation` compiler pass. But `ApplicationSaturation` pass does not handle `True`. Moreover, for our case, it is unnecessarily complicated.
When generating import/export bindings in local cache, they are included in the distribution.
Additionally, removed the hardcoded value for suggestions cache. Now one can generate them for local as well as for global cache, based on the presence or lack of `--no-global-cache` parameter.
Closes#5890.
This change downgrades hashing algorithm used in caching IR and library bindings to SHA-1. It is sufficient and significantly faster for the purpose of simple checksum we use it for.
Additionally, don't calculate the digest for serialized bytes - if we get the expected object type then we are confident about the integrity.
Don't initialize Jackson's ObjectMapper for every metadata serialization/de-serialization. Initialization is very costly.
Avoid unnecessary conversions between Scala and Java. Those back-and-forth `asScala` and `asJava` are pretty expensive.
Finally fix an SBT warning when generating library cache.
Closes https://github.com/enso-org/enso/issues/5763
# Important Notes
The change cuts roughly 0.8-1s from the overall startup.
This change will certainly lead to invalidation of existing caches. It is advised to simply start with a clean slate.
This change adds serialization and deserialization of library bindings.
In order to be functional, one needs to first generate IR and
serialize bindings using `--compiled <path-to-library>` command. The bindings
will be stored under the library with `.bindings` suffix.
Bindings are being generated during `buildEngineDistribution` task, thus not
requiring any extra steps.
When resolving import/exports the compiler will first try to load
module's bindings from cache. If successful, it will not schedule its
imports/exports for immediate compilation, as we always did, but use the
bindings info to infer the dependent modules.
The current change does not make any optimizations when it comes to
compiling the modules, yet. It only delays the actual
compilation/loading IR from cache so that it can be done in bulk.
Further optimizations will come from this opportunity such as parallel
loading of caches or lazily inferring only the necessary modules.
Part of https://github.com/enso-org/enso/issues/5568 work.
Automating the assembly of the engine and its execution into a single task. If you are modifying standard libraries, engine sources or Enso tests, you can launch `sbt` and then just:
```
sbt:enso> runEngineDistribution --run test/Tests/src/Data/Maybe_Spec.enso
[info] Engine package created at built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev
[info] Executing built-distribution/enso-engine-...-dev/bin/enso --run test/Tests/src/Data/Maybe_Spec.enso
Maybe: [5/5, 30ms]
- should have a None variant [14ms]
- should have a Some variant [5ms]
- should provide the `maybe` function [4ms]
- should provide `is_some` [2ms]
- should provide `is_none` [3ms]
5 tests succeeded.
0 tests failed.unEngineDistribution 4s
0 tests skipped.
```
the [runEngineDistribution](3a581f29ee/docs/CONTRIBUTING.md (running-enso)) `sbt` input task makes sure all your sources are properly compiled and only then executes your enso source. Everything ready at a single press of Enter.
# Important Notes
To debug in chrome dev tools, just add `--inspect`:
```
sbt:enso> runEngineDistribution --inspect --run test/Tests/src/Data/Maybe_Spec.enso
E.g. in Chrome open: devtools://devtools/bundled/js_app.html?ws=127.0.0.1:9229/7JsgjXlntK8
```
everything gets build and one can just attach the Enso debugger.
Upgrading to GraalVM 22.3.0.
# Important Notes
- Removed all deprecated `FrameSlot`, and replaced them with frame indexes - integers.
- Add more information to `AliasAnalysis` so that it also gathers these indexes.
- Add quick build mode option to `native-image` as default for non-release builds
- `graaljs` and `native-image` should now be downloaded via `gu` automatically, as dependencies.
- Remove `engine-runner-native` project - native image is now build straight from `engine-runner`.
- We used to have `engine-runner-native` without `sqldf` in classpath as a workaround for an internal native image bug.
- Fixed chrome inspector integration, such that it shows values of local variables both for current stack frame and caller stack frames.
- There are still many issues with the debugging in general, for example, when there is a polyglot value among local variables, a `NullPointerException` is thrown and no values are displayed.
- Removed some deprecated `native-image` options
- Remove some deprecated Truffle API method calls.
Make sure `libenso_parser.so`, `.dll` or `.dylib` are packaged and included when `sbt buildEngineDistribution`.
# Important Notes
There was [a discussion](https://discord.com/channels/401396655599124480/1036562819644141598) about proper location of the library. It was concluded that _"there's no functional difference between a dylib and a jar."_ and as such the library is placed in `component` folder.
Currently the old parser is still used for parsing. This PR just integrates the build system changes and makes us ready for smooth flipping of the parser in the future as part of #3611.
Auxiliary sbt commands for building individual
stdlib packages.
The commands check if the engine distribution was built at least once,
and only copy the necessary package files if necessary.
So far added:
- `buildStdLibBase`
- `buildStdLibDatabase`
- `buildStdLibTable`
- `buildStdLibImage`
- `buildStdLibGoogle_Api`

### Important Notes
Changed example image download to only proceed if the file did not exist before - thus cutting on the build time (the build used to download it _every_ time - which completely failed the build if network is down). A redownload can be forced by performing a fresh repository checkout.
