Implements `Warnings.get_all wrap_errors=True` which wraps warnings attached to values inside vectors with `Map_Error`, which includes the position of the value within the vector. See [the documentation](https://github.com/enso-org/enso/blob/develop/docs/semantics/wrapped-errors.md) for more details.
`get_all wrap_errors=True` does not change the warnings that are attached to values -- it wraps them before returning them to the caller, but does not change the original warnings attached to the values.
Wrapped warnings only appear attached to the vector itself. The values inside the vector do not have their warnings wrapped.
Warning propagation is not changed at all; `Warnings.get_all` (with default `wrap_errors=False`) behaves as before. `get_all wrap_errors=True` is meant to be used primarily by the IDE, although it can be used anywhere this wrapping is desired.
* Merged ArgumentAst and ArgumentPlaceholder into single class.
* Created `AnyWidget` input being a "general use" widget input. Most wigets try to match with it; the `Argument` input is now solely for WidgetArgument(Name) or those handling arguments in a specific way (like selector which want to show on arg name click).
* dynamic config is now part of widget input, and is properly propagated through vector editor/function widgets.
# Important Notes
The widgets still does not work perfectly:
* The chosen options often don't have argument placeholders - that's because we don't display them for constructors. Needs to be added on our side, or engine should send us methodCall info for constructors.
* There are issues with engine's messages sent to us. This makes widgets does not set up (so there is no drop-down, or vector adds `_` instead of default). I'm investigating them and going to fill issues.
Adds these JAR modules to the `component` directory inside Engine distribution:
- `graal-language-23.1.0`
- `org.bouncycastle.*` - these need to be added for graalpy language
# Important Notes
- Remove `org.bouncycastle.*` packages from `runtime.jar` fat jar.
- Make sure that the `./run` script preinstalls GraalPy standalone distribution before starting engine tests
- Note that using `python -m venv` is only possible from standalone distribution, we cannot distribute `graalpython-launcher`.
- Make sure that installation of `numpy` and its polyglot execution example works.
- Convert `Text` to `TruffleString` before passing to GraalPy - 8ee9a2816f
With herein proposed change one can pass an optional filter to `enso --run test/Benchmarks` to execute only groups and specs that contain given string in its name.

Changelog:
- add: `cmd`+`shift`+`,` and `cmd`+`shift`+`.` shortcuts to start and stop the backend profiling. Profiling data is stored on disk.
Changelog:
- update: always create an event log next to the profiling file when the engine is started with the `--profiling-path` flag
- remove: `--profiling-events-log-path` flag
Ensure that `-Dbench.compileOnly` system property is correctly forwarded to the benchmarks' runner. So that in the CI Engine tests, benchmarks are *dry run*.

```
With SDKMan, download with `sdk install java 21-graalce`.
# 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`.

Changelog:
- add: `profiling/start` request starts the sampler and starts collecting runtime events to the log file
- add: `profiling/stop` request stop the sampler and write the profiling data to the `$ENSO_DATA_DIR/profiling` directory
- refactor: rewrite the profiling logic into Java
After a discussion, I was really curious that our panics are supposed to be almost free - and while trusting that statement, it was really hard to believe - so I wanted to see for myself - knowing that an experiment is the most robust source of this kind of information - testing that in practice.
So I wrote a benchmark comparing various ways of reporting errors, also testing them both at 'shallow' and 'deep' stack traces (adding 200 additional frames) - to see how stack depth affects them, if at all.
The panics are indeed blazing fast! Kudos to the engine team. However, it seems that our dataflow errors are relatively slow (and we tend to use them _more_ than panics and want to be using them more and more). This uncovers a possible optimization opportunity. Can we make them as fast as panics??
Analysis of the benchmark results in comment below.
* Add support for https and wss
Preliminary support for https and wss. During language server startup we
will read the application config and search for the `https` config with
necessary env vars set.
The configuration supports two modes of creating ssl-context - via
PKCS12 format and certificat+private key.
Fixes#7839.

Adds the ability to declare a module as *private*. Modifies the parser to add the `private` keyword as a reserved keyword. All the checks for private modules are implemented as an independent *Compiler pass*. No checks are done at runtime.
# Important Notes
- Introduces new keyword - `private` - a reserved keyword.
- Modules that have `private` keyword as the first statement are declared as *private* (Project private)
- Public module cannot have private submodules and vice versa.
- This would require runtime access checks
- See #7088 for the specification.
* Enable log-to-file configuration
PR #7825 enabled parallel logging to a file with a much more
fine-grained log level by default.
However, logging at `TRACE` level on Windows appears to be still
problematic.
This PR reduced the default log level to file from `DEBUG` to `TRACE`
and allows to control it via an environment variable if one wishes to
change the verbosity without making code changes.
* PR comments
* Always log verbose to a file
The change adds an option by default to always log to a file with
verbose log level.
The implementation is a bit tricky because in the most common use-case
we have to always log in verbose mode to a socket and only later apply
the desired log levels. Previously socket appender would respect the
desired log level already before forwarding the log.
If by default we log to a file, verbose mode is simply ignored and does
not override user settings.
To test run `project-manager` with `ENSO_LOGSERVER_APPENDER=console` env
variable. That will output to the console with the default `INFO` level
and `TRACE` log level for the file.
* add docs
* changelog
* Address some PR requests
1. Log INFO level to CONSOLE by default
2. Change runner's default log level from ERROR to WARN
Took a while to figure out why the correct log level wasn't being passed
to the language server, therefore ignoring the (desired) verbose logs
from the log file.
* linter
* 3rd party uses log4j for logging
Getting rid of the warning by adding a log4j over slf4j bridge:
```
ERROR StatusLogger Log4j2 could not find a logging implementation. Please add log4j-core to the classpath. Using SimpleLogger to log to the console...
```
* legal review update
* Make sure tests use test resources
Having `application.conf` in `src/main/resources` and `test/resources`
does not guarantee that in Tests we will pick up the latter. Instead, by
default it seems to do some kind of merge of different configurations,
which is far from desired.
* Ensure native launcher test log to console only
Logging to console and (temporary) files is problematic for Windows.
The CI also revealed a problem with the native configuration because it
was not possible to modify the launcher via env variables as everything
was initialized during build time.
* Adapt to method changes
* Potentially deal with Windows failures
* Improve shutdown logic of language server
This PR addresses problems mentioned in #7470 and #7729:
- shutting a language server explicitly will not lead to a soft shutdown
- `project/status` endpoint returns the state of the language server
`LanguageServerController` now also signed up for `ClientConnect`
messages. For it to be unambiguous, we need to carry around the port
number of the language server as a way of identifying the right one.
One can now use `project/status` to additionally determine the state of
the language server.
Also relies on a proper fix for #7765.
* changelog
* PR comments
# Important Notes
- Binary LS endpoint is not yet handled.
- The parsing of provided source is not entirely correct, as each line (including imports) is treated as node. The usage of actual enso AST for nodes is not yet implemented.
- Modifications to the graph state are not yet synchronized back to the language server.
This change replaces Enso's custom logger with an existing, mostly off the shelf logging implementation. The change attempts to provide a 1:1 replacement for the existing solution while requiring only a minimal logic for the initialization.
Loggers are configured completely via `logging-server` section in `application.conf` HOCON file, all initial logback configuration has been removed. This opens up a lot of interesting opportunities because we can benefit from all the well maintained slf4j implementations without being to them in terms of functionality.
Most important differences have been outlined in `docs/infrastructure/logging.md`.
# Important Notes
Addresses:
- #7253
- #6739
- Closes#7633
- Moves `Round_Spec.enso` from published `Standard.Test` into our `test/Tests` project; the `Table_Tests` that depend on it, simply `import enso_dev.Tests`.
- Changes the layout of the local libraries directory:
- It used to be `root/<namespace>/<name>`.
- Now it is `root/<dir>` - the namespace and name are now read from `package.yaml` instead.
- Adds the parent directory of the current project to the default `ENSO_LIBRARY_PATH`.
- It is treated as a secondary path, so the default `ENSO_HOME/lib` still takes precedence.
- This allows projects to reference and load 'sibling' projects easily - the only requirement is for the project to enable `prefer-local-libraries: true` or add the other local project to its edition. The edition resolution logic is **not changed**.
Refactoring deeply nested IR classes to shallow nesting.
Fixes#7017
# Important Notes
It's a big PR but fairly consistent. Split multiple hierarchy levels into subpackages.
- Update list of groups to agreed list.
- Lower case `ALIAS` names to be consistent with function names.
- Add `GROUP` to methods.
- All constructors and functions have doc comments.
- Correct a few typos (e.g. `PRVIATE`).
- Mark some more things as `PRIVATE`.
- Use `ToDo:` and `Note:` consistently.
- Order tags in doc comment.
# Important Notes
We don't have all the doc comments on types and will want to add them in future,

# Important Notes
#### The Plot
- there used to be two kinds of benchmarks: in Java and in Enso
- those in Java got quite a good treatment
- there even are results updated daily: https://enso-org.github.io/engine-benchmark-results/
- the benchmarks written in Enso used to be 2nd class citizen
#### The Revelation
This PR has the potential to fix it all!
- It designs new [Bench API](88fd6fb988) ready for non-batch execution
- It allows for _single benchmark in a dedicated JVM_ execution
- It provides a simple way to wrap such an Enso benchmark as a Java benchmark
- thus the results of Enso and Java benchmarks are [now unified](https://github.com/enso-org/enso/pull/7101#discussion_r1257504440)
Long live _single benchmarking infrastructure for Java and Enso_!
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.

part of #7178
Changelog:
- add: `text/fileModifiedOnDisk` notification
- update: during the auto-save, check if the file is modified on disk and send the notification. I.e. auto-save does not overwrite the file if it was changed on disk (but the save command does)
- update: IDE handles the file-modified-on-disk notification and reloads the module from disk
# Important Notes
Currently, the auto-save (and the check that the file is modified on disk) is triggered only after the file was edited. The proper check (using the file-watcher service) will be added in the next PR
https://github.com/enso-org/enso/assets/357683/ff91f3e6-2f7a-4c01-a745-98cb140e1964
`executionFailed` instead is sent when an evaulation finishes with a a critical failure or a non-critical error.
The PR tries to miniminally modify the change in the messages exchange so as to avoid a major redesign at this point.
Closes#7002.
# Important Notes
Unblocks IDE which will need to modify to this new setup.
Fixes#6955 by:
- using `visualisationModule` to specify the module where the visualization is to be used
- referring to method in `Meta.get_annotation` with `.method_name` - e.g. unresolved symbol notation
- evaluating arguments to `Meta.get_annotation` in the context of the user module (which can access the extension functions)
Several small changes:
- Dropdowns: Populate `GridView` lazily (fixes#6865).
- Clear disconnected edges when editing node (fixes case 1 in #7018).
- Fix regression in node selection rendering (2nd bug in #6975).
- Update profiler docs. The hotkey to *prOfile without exiting* is now `Ctrl+Alt+O` (`Ctrl+Alt+P` has been requisitioned by the CB).

# Important Notes
- `Rectangle`: When `inset > border`, the extra space is now between the body and the border, not outside the border.
- More robust node layering logic. Now an inconsistent layer order cannot occur, even if something strange happens (like editing an expression and an edge at the same time).
- The dynamic drop down in the `drop_down` example scene doesn't show any entries before (or after) this, so I can't test the dynamic case.

# Important Notes
This is more or less a straight port from Rust; I think the goal should be to make this a sort of living document which changes as the TypeScript parts of the codebase become more mature.

- update: sqlite dependency
- remove: unused methods from `SuggestionsRepo`
- remove: Arguments table

Some small improvements relating to rendering:
- Add a debug option: `-debug.pixel-read-period`. This can be used to measure the performance impact of checking the pointer location on different hardware. [On my development box, it makes no difference to performance.] (Closes#5490).
- Unbind pixel pack buffers after each use. This is recommended practice. It has no performance impact on my machine, and allows SpectorJS to run (`-debug.enable-spector`). (Closes#5941).
Also, simplify the profiling CLI: the `profile.load-profile` and `profile.save-profile` options have been renamed to `profile.load`/`profile.save`; `profile.save` now has a default filename, so you can capture a profile at any time in Electron with Ctrl+Alt+P and it will be written to `profile.json`.
Implement new Enso documentation parser; remove old Scala Enso parser.
Performance: Total time parsing documentation is now ~2ms.
# Important Notes
- Doc parsing is now done only in the frontend.
- Some engine tests had never been switched to the new parser. We should investigate tests that don't pass after the switch: #5894.
- The option to run the old searcher has been removed, as it is obsolete and was already broken before this (see #5909).
- Some interfaces used only by the old searcher have been removed.
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.

everything gets build and one can just attach the Enso debugger.
Closes#5036
Move the logic that looks up method pointers from the language server to IDE. This way we can keep the suggestion updates and expression updates async, otherwise it will hurt the initial startup time of LS.
Fixes the issue when some expression updates does not contain the method pointer.
Start `project-manager` with following options to provide first 20s of the startup sequence:
```
$ project-manager --profiling-events-log-path=start.log --profiling-path=start.npss --profiling-time=20
```
once the `start.log` and `start.npss` files are generated (next to each other), open them in GraalVM's VisualVM:
```
$ graalvm/bin/jvisualvm --openfile start.npss
```
analyze.
VCS restore operation was correctly restoring the state of projects to the requested commit. Unfortunately, after the operation file system was becoming out-of-sync with language server's buffers (and IDE's content versions).
A few important changes are introduced here that complicate the interaction between components:
1) `vcs restore` returns an actual diff between the current state and the
requested commit
2) the response is forwarded to buffer registry first rather than to the client
3) the diff is used to identify appropriate collaborative editors and
notify them about the need to reload buffers from file system
4) all clients of affected open buffers are notified of the change via
`text/didChange` notification. If a file was removed and there were open buffers for it, clients will be notified via `file/event` and editor will be stopped
5) only then the client is notified about a successful restore operation
This PR addresses one of the two problems reported in https://www.pivotaltracker.com/story/show/184097084.
# Important Notes
We need to make sure that IDE correctly responds to `text/didChange` notifications.
`Any.==` is a builtin method. The semantics is the same as it used to be, except that we no longer assume `x == y` iff `Meta.is_same_object x y`, which used to be the case and caused failures in table tests.
# Important Notes
Measurements from `EqualsBenchmarks` shows that the performance of `Any.==` for recursive atoms increased by roughly 20%, and the performance for primitive types stays roughly the same.
Apparently
```
git --git-dir .enso/.vcs log refs/heads/master
fatal: ambiguous argument 'refs/heads/master': unknown revision or path not in the working tree.
```
but
```
git --git-dir .enso/.vcs log HEAD
fatal: ambiguous argument 'refs/heads/master': unknown revision or path not in the working tree.
```
works just fine on Windows.
Added some safeguards to avoid propagating weird errors because of retrieving element from an
empty Option.
Allow arbitrary expression evaluation in the chromeinspector console. Moreover, allow modifications of any variable in any stack frame.
# Important Notes
- Implement inline parsing in `EnsoLanguage.parse(InlineParsingRequest)`.
- Debugging experience is affected by this [bug in Truffle](https://github.com/oracle/graal/issues/5513), which causes NPEs when a host object gets into chromeinspector. I tried to implement a workaround, but it does not work all the time. Nevertheless, it should not matter that much - if there is a NPE in the debugger, you can just ignore it, as it should be concealed in the debugger and should not be propagted outside. See comments in the `docs/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.
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.
The main culprit of a Vector slowdown (when compared to Array) was the normalization of the index when accessing the elements. Turns out that the Graal was very persistent on **not** inlining that particular fragment and that was degrading the results in benchmarks.
Being unable to force it to do it (looks like a combination of thunk execution and another layer of indirection) we resorted to just moving the normalization to the builtin method. That makes Array and Vector perform roughly the same.
Moved all handling of invalid index into the builtin as well, simplifying the Enso implementation. This also meant that `Vector.unsafe_at` is now obsolete.
Additionally, added support for negative indices in Array, to behave in the same way as for Vector.
# Important Notes
Note that this workaround only addresses this particular perf issue. I'm pretty sure we will have more of such scenarios.
Before the change `averageOverVector` benchmark averaged around `0.033 ms/op` now it does consistently `0.016 ms/op`, similarly to `averageOverArray`.
- 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.
When nodes get invalidated in the cache, they have to be recomputed. Let the IDE know which of the nodes are pending by sending `Api.ExpressionUpdate.Payload.Pending` message.
# Important Notes
This PR introduces new `Api.ExpressionUpdate.Payload.Pending` message. This message is delivered before re-computation of nodes. Later `Api.ExpressionUpdate.Payload.Value` or other is sent to notify the IDE that a value for given node is available.
Trivial implementation of of the `Api.ExpressionUpdate.Payload.Pending` message in the IDE is provided by this PR to (improperly) visualize pending node status - further improvements needed in follow up PRs.
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.
