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.
Previously, when exporting the same module multiple times only the first statement would count and the rest would be discarded by the compiler.
This change allows for multiple exports of the same module e.g.,
```
export project.F1
from project.F1 export foo
```
Multiple exports may however lead to conflicts when combined with hiding names. Added logic in `ImportResolver` to detect such scenarios.
This fixes https://www.pivotaltracker.com/n/projects/2539304/stories/183092447
# Important Notes
Added a bunch of scenarios to simulate pos and neg results.
1-to-1 translation of the HTTPBin expected by our testsuite using Java's HttpServer.
Can be started from SBT via
```
sbt:enso> simple-httpbin/run <hostname> <port>
```
# Important Notes
@mwu-tow this will mean we can ditch Go dependency completely and replace it with the above call.
This change adds support for Version Controlled projects in language server.
Version Control supports operations:
- `init` - initialize VCS for a project
- `save` - commit all changes to the project in VCS
- `restore` - ability to restore project to some past `save`
- `status` - show the status of the project from VCS' perspective
- `list` - show a list of requested saves
# Important Notes
Behind the scenes, Enso's VCS uses git (or rather [jGit](https://www.eclipse.org/jgit/)) but nothing stops us from using a different implementation as long as it conforms to the establish API.
- Added expression ANTLR4 grammar and sbt based build.
- Added expression support to `set` and `filter` on the Database and InMemory `Table`.
- Added expression support to `aggregate` on the Database and InMemory `Table`.
- Removed old aggregate functions (`sum`, `max`, `min` and `mean`) from `Column` types.
- Adjusted database `Column` `+` operator to do concatenation (`||`) when text types.
- Added power operator `^` to both `Column` types.
- Adjust `iif` to allow for columns to be passed for `when_true` and `when_false` parameters.
- Added `is_present` to database `Column` type.
- Added `coalesce`, `min` and `max` functions to both `Column` types performing row based operation.
- Added support for `Date`, `Time_Of_Day` and `Date_Time` constants in database.
- Added `read` method to InMemory `Column` returning `self` (or a slice).
# Important Notes
- Moved approximate type computation to `SQL_Type`.
- Fixed issue in `LongNumericOp` where it was always casting to a double.
- Removed `head` from InMemory Table (still has `first` method).
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.
We've had an old attempt at integrating a Rust parser with our Scala/Java projects. It seems to have been abandoned and is not used anywhere - it is also superseded by the new integration of the Rust parser. I think it was used as an experiment to see how to approach such an integration.
Since it is not used anymore - it make sense to remove it, because it only adds some (slight, but non-zero) maintenance effort. We can always bring it back from git history if necessary.
- Reimplement the `Duration` type to a built-in type.
- `Duration` is an interop type.
- Allow Enso method dispatch on `Duration` interop coming from different languages.
# Important Notes
- The older `Duration` type should now be split into new `Duration` builtin type and a `Period` type.
- This PR does not implement `Period` type, so all the `Period`-related functionality is currently not working, e.g., `Date - Period`.
- This PR removes `Integer.milliseconds`, `Integer.seconds`, ..., `Integer.years` extension methods.
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

```
# 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.
Implements https://www.pivotaltracker.com/story/show/182307143
# Important Notes
- Modified standard library Java helpers dependencies so that `std-table` module depends on `std-base`, as a provided dependency. This is allowed, because `std-table` is used by the `Standard.Table` Enso module which depends on `Standard.Base` which ensures that the `std-base` is loaded onto the classpath, thus whenever `std-table` is loaded by `Standard.Table`, so is `std-base`. Thus we can rely on classes from `std-base` and its dependencies being _provided_ on the classpath. Thanks to that we can use utilities like `Text_Utils` also in `std-table`, avoiding code duplication. Additional advantage of that is that we don't need to specify ICU4J as a separate dependency for `std-table`, since it is 'taken' from `std-base` already - so we avoid including it in our build packages twice.
This change adds support for matching on constants by:
1) extending parser to allow literals in patterns
2) generate branch node for literals

Execution of `sbt runtime/bench` doesn't seem to be part of the gate. As such it can happen a change into the Enso language syntax, standard libraries, runtime & co. can break the benchmarks suite without being noticed. Integrating such PR causes unnecessary disruptions to others using the benchmarks.
Let's make sure verification of the benchmarks (e.g. that they compile and can execute without error) is part of the CI.
# Important Notes
Currently the gate shall fail. The fix is being prepared in parallel PR - #3639. When the two PRs are combined, the gate shall succeed again.
The option asks to print a final test report for each projects at the
end `sbt> run`.
That way, when running the task in aggregate mode, we have a summary at
the end, rather than somewhere in the large output of the individual
subproject.
Updated the SQLite, PostgreSQL and Redshift drivers.
# Important Notes
Updated the API for Redshift and proved able to connect without the ini file workaround.
This PR merges existing variants of `LiteralNode` (`Integer`, `BigInteger`, `Decimal`, `Text`) into a single `LiteralNode`. It adds `PatchableLiteralNode` variant (with non `final` `value` field) and uses `Node.replace` to modify the AST to be patchable. With such change one can remove the `UnwindHelper` workaround as `IdExecutionInstrument` now sees _patched_ return values without any tricks.
This change makes sure that Runtime configuration of `runtime` is listed
as a dependency of `runtime-with-instruments`.
That way `buildEngineDistribution` which indirectly depends on
`runtime-with-instruments`/assembly triggers compilation for std-bits,
if necessary.
# Important Notes
Minor adjustments for a problem introduced in https://github.com/enso-org/enso/pull/3509
New plan to [fix the `sbt` build](https://www.pivotaltracker.com/n/projects/2539304/stories/182209126) and its annoying:
```
log.error(
"Truffle Instrumentation is not up to date, " +
"which will lead to runtime errors\n" +
"Fixes have been applied to ensure consistent Instrumentation state, " +
"but compilation has to be triggered again.\n" +
"Please re-run the previous command.\n" +
"(If this for some reason fails, " +
s"please do a clean build of the $projectName project)"
)
```
When it is hard to fix `sbt` incremental compilation, let's restructure our project sources so that each `@TruffleInstrument` and `@TruffleLanguage` registration is in individual compilation unit. Each such unit is either going to be compiled or not going to be compiled as a batch - that will eliminate the `sbt` incremental compilation issues without addressing them in `sbt` itself.
fa2cf6a33ec4a5b2e3370e1b22c2b5f712286a75 is the first step - it introduces `IdExecutionService` and moves all the `IdExecutionInstrument` API up to that interface. The rest of the `runtime` project then depends only on `IdExecutionService`. Such refactoring allows us to move the `IdExecutionInstrument` out of `runtime` project into independent compilation unit.
Auto-generate all builtin methods for builtin `File` type from method signatures.
Similarly, for `ManagedResource` and `Warning`.
Additionally, support for specializations for overloaded and non-overloaded methods is added.
Coverage can be tracked by the number of hard-coded builtin classes that are now deleted.
## Important notes
Notice how `type File` now lacks `prim_file` field and we were able to get rid off all of those
propagating method calls without writing a single builtin node class.
Similarly `ManagedResource` and `Warning` are now builtins and `Prim_Warnings` stub is now gone.
Drop `Core` implementation (replacement for IR) as it (sadly) looks increasingly
unlikely this effort will be continued. Also, it heavily relies
on implicits which increases some compilation time (~1sec from `clean`)
Related to https://www.pivotaltracker.com/story/show/182359029
This change introduces a custom LogManager for console that allows for
excluding certain log messages. The primarily reason for introducing
such LogManager/Appender is to stop issuing hundreds of pointless
warnings coming from the analyzing compiler (wrapper around javac) for
classes that are being generated by annotation processors.
The output looks like this:
```
[info] Cannot install GraalVM MBean due to Failed to load org.graalvm.nativebridge.jni.JNIExceptionWrapperEntryPoints
[info] compiling 129 Scala sources and 395 Java sources to /home/hubert/work/repos/enso/enso/engine/runtime/target/scala-2.13/classes ...

....
```
The output now has over 500 of those and there will be more. Much more
(generated by our and Truffle processors).
There is no way to tell SBT that those are OK. One could potentially
think of splitting compilation into 3 stages (Java processors, Java and
Scala) but that will already complicate the non-trivial build definition
and we may still end up with the initial problem.
This is a fix to make it possible to get reasonable feedback from
compilation without scrolling mutliple screens *every single time*.
Also fixed a spurious warning in javac processor complaining about
creating files in the last round.

`interpreter-dsl` should only attempt to run explicitly specified
processors. That way, even if the generated
`META-INF/services/javax.annotation.processing.Processor` is present,
it does not attempt to apply those processors on itself.
This change makes errors related to
```
[warn] Unexpected javac output: error: Bad service configuration file, or
exception thrown while constructing Processor object:
javax.annotation.processing.Processor: Provider org.enso.interpreter.dsl....
```
a thing of the past. This was supper annoying when switching branches and
required to either clean the project or remove the file by hand.

@radeusgd discovered that no formatting was being applied to std-bits projects.
This was caused by the fact that `enso` project didn't aggregate them. Compilation and
packaging still worked because one relied on the output of some tasks but
```
sbt> javafmtAll
```
didn't apply it to `std-bits`.
# Important Notes
Apart from `build.sbt` no manual changes were made.
This is the 2nd part of DSL improvements that allow us to generate a lot of
builtins-related boilerplate code.
- [x] generate multiple method nodes for methods/constructors with varargs
- [x] expanded processing to allow for @Builtin to be added to classes and
and generate @BuiltinType classes
- [x] generate code that wraps exceptions to panic via `wrapException`
annotation element (see @Builtin.WrapException`
Also rewrote @Builtin annotations to be more structured and introduced some nesting, such as
@Builtin.Method or @Builtin.WrapException.
This is part of incremental work and a follow up on https://github.com/enso-org/enso/pull/3444.
# Important Notes
Notice the number of boilerplate classes removed to see the impact.
For now only applied to `Array` but should be applicable to other types.
Before, when running Enso with `-ea`, some assertions were broken and the interpreter would not start.
This PR fixes two very minor bugs that were the cause of this - now we can successfully run Enso with `-ea`, to test that any assertions in Truffle or in our own libraries are indeed satisfied.
Additionally, this PR adds a setting to SBT that ensures that IntelliJ uses the right language level (Java 17) for our projects.
A low-hanging fruit where we can automate the generation of many
@BuiltinMethod nodes simply from the runtime's methods signatures.
This change introduces another annotation, @Builtin, to distinguish from
@BuiltinType and @BuiltinMethod processing. @Builtin processing will
always be the first stage of processing and its output will be fed to
the latter.
Note that the return type of Array.length() is changed from `int` to
`long` because we probably don't want to add a ton of specializations
for the former (see comparator nodes for details) and it is fine to cast
it in a small number of places.
Progress is visible in the number of deleted hardcoded classes.
This is an incremental step towards #181499077.
# Important Notes
This process does not attempt to cover all cases. Not yet, at least.
We only handle simple methods and constructors (see removed `Array` boilerplate methods).
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`

In order to analyse why the `runner.jar` is slow to start, let's _"self sample"_ it using the [sampler library](https://bits.netbeans.org/dev/javadoc/org-netbeans-modules-sampler/org/netbeans/modules/sampler/Sampler.html). As soon as the `Main.main` is launched, the sampling starts and once the server is up, it writes its data into `/tmp/language-server.npss`.
Open the `/tmp/language-server.npss` with [VisualVM](https://visualvm.github.io) - you should have one copy in your
GraalVM `bin/jvisualvm` directory and there has to be a GraalVM to run Enso.
#### Changelog
- add: the `MethodsSampler` that gathers information in `.npss` format
- add: `--profiling` flag that enables the sampler
- add: language server processes the updates in batches
Finally this pull request proposes `--inspect` option to allow [debugging of `.enso`](e948f2535f/docs/debugger/README.md) in Chrome Developer Tools:
```bash
enso$ ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --inspect --run ./test/Tests/src/Data/Numbers_Spec.enso
Debugger listening on ws://127.0.0.1:9229/Wugyrg9Nm4OUL9YhzdcElmLft71ayZW3LMUPCdPyNAY
For help, see: https://www.graalvm.org/tools/chrome-debugger
E.g. in Chrome open: devtools://devtools/bundled/js_app.html?ws=127.0.0.1:9229/Wugyrg9Nm4OUL9YhzdcElmLft71ayZW3LMUPCdPyNAY
```
copy the printed URL into chrome browser and you should see:
One can also debug the `.enso` files in NetBeans or [VS Code with Apache Language Server extension](https://cwiki.apache.org/confluence/display/NETBEANS/Apache+NetBeans+Extension+for+Visual+Studio+Code) just pass in special JVM arguments:
```bash
enso$ JAVA_OPTS=-agentlib:jdwp=transport=dt_socket,server=y,address=8000 ./built-distribution/enso-engine-0.0.0-dev-linux-amd64/enso-0.0.0-dev/bin/enso --run ./test/Tests/src/Data/Numbers_Spec.enso
Listening for transport dt_socket at address: 8000
```
and then _Debug/Attach Debugger_. Once connected choose the _Toggle Pause in GraalVM Script_ button in the toolbar (the "G" button):
and your execution shall stop on the next `.enso` line of code. This mode allows to debug both - the Enso code as well as Java code.
Originally started as an attempt to write test in Java:
* test written in Java
* support for JUnit in `build.sbt`
* compile Java with `-g` - so it can be debugged
* Implementation of `StatementNode` - only gets created when `materialize` request gets to `BlockNode`
This PR replaces hard-coded `@Builtin_Method` and `@Builtin_Type` nodes in Builtins with an automated solution
that a) collects metadata from such annotations b) generates `BuiltinTypes` c) registers builtin methods with corresponding
constructors.
The main differences are:
1) The owner of the builtin method does not necessarily have to be a builtin type
2) You can now mix regular methods and builtin ones in stdlib
3) No need to keep track of builtin methods and types in various places and register them by hand (a source of many typos or omissions as it found during the process of this PR)
Related to #181497846
Benchmarks also execute within the margin of error.
### Important Notes
The PR got a bit large over time as I was moving various builtin types and finding various corner cases.
Most of the changes however are rather simple c&p from Builtins.enso to the corresponding stdlib module.
Here is the list of the most crucial updates:
- `engine/runtime/src/main/java/org/enso/interpreter/runtime/builtin/Builtins.java` - the core of the changes. We no longer register individual builtin constructors and their methods by hand. Instead, the information about those is read from 2 metadata files generated by annotation processors. When the builtin method is encountered in stdlib, we do not ignore the method. Instead we lookup it up in the list of registered functions (see `getBuiltinFunction` and `IrToTruffle`)
- `engine/runtime/src/main/java/org/enso/interpreter/runtime/callable/atom/AtomConstructor.java` has now information whether it corresponds to the builtin type or not.
- `engine/runtime/src/main/scala/org/enso/compiler/codegen/RuntimeStubsGenerator.scala` - when runtime stubs generator encounters a builtin type, based on the @Builtin_Type annotation, it looks up an existing constructor for it and registers it in the provided scope, rather than creating a new one. The scope of the constructor is also changed to the one coming from stdlib, while ensuring that synthetic methods (for fields) also get assigned correctly
- `engine/runtime/src/main/scala/org/enso/compiler/codegen/IrToTruffle.scala` - when a builtin method is encountered in stdlib we don't generate a new function node for it, instead we look it up in the list of registered builtin methods. Note that Integer and Number present a bit of a challenge because they list a whole bunch of methods that don't have a corresponding method (instead delegating to small/big integer implementations).
During the translation new atom constructors get initialized but we don't want to do it for builtins which have gone through the process earlier, hence the exception
- `lib/scala/interpreter-dsl/src/main/java/org/enso/interpreter/dsl/MethodProcessor.java` - @Builtin_Method processor not only generates the actual code fpr nodes but also collects and writes the info about them (name, class, params) to a metadata file that is read during builtins initialization
- `lib/scala/interpreter-dsl/src/main/java/org/enso/interpreter/dsl/MethodProcessor.java` - @Builtin_Method processor no longer generates only (root) nodes but also collects and writes the info about them (name, class, params) to a metadata file that is read during builtins initialization
- `lib/scala/interpreter-dsl/src/main/java/org/enso/interpreter/dsl/TypeProcessor.java` - Similar to MethodProcessor but handles @Builtin_Type annotations. It doesn't, **yet**, generate any builtin objects. It also collects the names, as present in stdlib, if any, so that we can generate the names automatically (see generated `types/ConstantsGen.java`)
- `engine/runtime/src/main/java/org/enso/interpreter/node/expression/builtin` - various classes annotated with @BuiltinType to ensure that the atom constructor is always properly registered for the builitn. Note that in order to support types fields in those, annotation takes optional `params` parameter (comma separated).
- `engine/runtime/src/bench/scala/org/enso/interpreter/bench/fixtures/semantic/AtomFixtures.scala` - drop manual creation of test list which seemed to be a relict of the old design
* Initial integration with Frgaal in sbt
Half-working since it chokes on generated classes from annotation
processor.
* Replace AutoService with ServiceProvider
For reasons unknown AutoService would fail to initialize and fail to
generate required builtin method classes.
Hidden error message is not particularly revealing on the reason for
that:
```
[error] error: Bad service configuration file, or exception thrown while constructing Processor object: javax.annotation.processing.Processor: Provider com.google.auto.service.processor.AutoServiceProcessor could not be instantiated
```
The sample records is only to demonstrate that we can now use newer Java
features.
* Cleanup + fix benchmark compilation
Bench requires jmh classes which are not available because we obviously
had to limit `java.base` modules to get Frgaal to work nicely.
For now, we default to good ol' javac for Benchmarks.
Limiting Frgaal to runtime for now, if it plays nicely, we can expand it
to other projects.
* Update CHANGELOG
* Remove dummy record class
* Update licenses
* New line
* PR review
* Update legal review
