Changelog:
- update: instead of relying on the connection closed events, the `sendSuggestionsDatabase` request initiates the suggestions database re-indexing
Fixes the _RefactoringTests - rename project_ part of the #7775
Changelog:
- update: send the ok response before the notification to fix the order of events in tests
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`.

- 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**.

After moving the rename action to the dashboard, IDE is unaware of the new project name. PR implements a new `refactoring/projectRenamed` notification that is sent from the server to clients and informs them about the changed project name.

We can't really control the timing of file watcher events, which sometimes leads to failures of VCS tests. The PR disables the file watcher in the `VcsManagerTest` suite to make tests more stable.
Changelog:
- add: a `Watcher` and `WatcherFactory` interfaces
- add: a `NoopWatcher` test watcher
- update: disable the file watcher in the `VcsManagerTest` suite
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

As discovered in #7224, Json RPC protocol was added to the asynchronous resource initialization stage, as part of #6306, but was not in fact initialized at that point.
Instead it was initialized when the server was started to be able to serve correctly the initialization messages. A classic Catch-22. It was really hard to discover this just by looking at the code, but the profiling clearly showed where the time was spent.
This change splits Language Server's protocol into two:
- the first one accepts `heartbeat/init` and `session/initProtocolConnection`
- the second one enriches it with the full set of supported messages
This shifts the initialization from blocking for 0.5 sec to only ~30ms, and performing the second stage asynchronously.
Closes#7224.
# Important Notes
Before the change (blocking server startup):
After the change (1st stage):
After the change (2nd, asynchronous initialization, stage):
Package's config information, once loaded, never changed. While there is typically no need for it, this was problematic when the config became out-of-sync with the filesystem, like in the case of project rename action.
In rename, the config's properties would be updated in the FS, but that would never be reflected in module's package. Therefore further compilations would continue to ask for the old namespace.
Most of the changes are cosmetic (s/`.config`/`.getConfig()`) except for the new `reloadConfig` method on `Package` that is being called in `RenameProjectCmd` handler.
Closes#7062.
# Important Notes
The reported `ExecutionFailed` error should have been mostly fixed already via #7143. This change makes sure that all the related warnings are gone as well and the compiler uses the updated namespace.
`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)
Request Timeouts started plaguing IDE due to numerous `executionContext/***Visualization` requests. While caused by a bug they revealed a bigger problem in the Language Server when serving large amounts of requests:
1) Long and short lived jobs are fighting for various locks. Lock contention leads to some jobs waiting for a longer than desired leading to unexpected request timeouts. Increasing timeout value is just delaying the problem.
2) Requests coming from IDE are served almost instantly and handled by various commands. Commands can issue further jobs that serve request. We apparently have and always had a single-thread thread pool for serving such jobs, leading to immediate thread starvation.
Both reasons increase the chances of Request Timeouts when dealing with a large number of requests. For 2) I noticed that while we used to set the `enso-runtime-server.jobParallelism` option descriptor key to some machine-dependent value (most likely > 1), the value set would **only** be available for instrumentation. `JobExecutionEngine` where it is actually used would always get the default, i.e. a single-threaded ThreadPool. This means that this option descriptor was simply misused since its introduction. Moved that option to runtime options so that it can be set and retrieved during normal operation.
Adding parallelism intensified problem 1), because now we could execute multiple jobs and they would compete for resources. It also revealed a scenario for a yet another deadlock scenario, due to invalid order of lock acquisition. See `ExecuteJob` vs `UpsertVisualisationJob` order for details.
Still, a number of requests would continue to randomly timeout due to lock contention. It became apparent that
`Attach/Modify/Detach-VisualisationCmd` should not wait until a triggered `UpsertVisualisationJob` sends a response to the client; long and short lived jobs will always compete for resources and we cannot guarantee that they will not timeout that way. That is why the response is sent immediately from the command handler and not from the job executed after it.
This brings another problematic scenario:
1. `AttachVisualisationCmd` is executed, response sent to the client, `UpsertVisualisationJob` scheduled.
2. In the meantime `ModifyVisualisationCmd` comes and fails; command cannot find the visualization that will only be added by `UpsertVisualisationJob`, which might have not yet been scheduled to run.
Remedied that by checking visualisation-related jobs that are still in progress. It also allowed for cancelling jobs which results wouldn't be used anyway (`ModifyVisualisationCmd` sends its own `UpsertVisualisationJob`). This is not a theoretical scenario, it happened frequently on IDE startup.
This change does not fully solve the rather problematic setup of numerous locks, which are requested by short and long lived jobs. A better design should still be investigated. But it significantly reduces the chances of Request Timeouts which IDE had to deal with.
With this change I haven't been able to experience Request Timeouts for relatively modest projects anymore.
I added the possibility of logging wait times for locks to better investigate further problems.
Closes#7005

Changelog:
- add: new suggestion type Getter that is not exposed to the api
- update: do not return suggestion of type getter when doing a global search (without specifying self types)
Private suggestions and modules mentioned in the issue will be filtered out after we finish the work on the new (refined) exports algorithm.
# Important Notes
close#6800
Update the `executionContext/expressionUpdates` notification and send the list of not applied arguments in addition to the method pointer.
# Important Notes
IDE is updated to support the new API.
The change adds an additional field to `ExpressionUpdates` messages sent by `ProgramExecutionSupport` to indicate if the type of value (or its method pointer) has changed and therefore would potentially require a suggestions' update.
Prior to #3729 that check was done during the instrumentation. However we still want to continue to support "pending expression" functionality therefore `SuggestionsHandler` will use the additional information to filter only the required expression updates.
Most of the changes are related to adapting our tests to the new field.
Closes#6706.
# Important Notes
The associated project now loads and navigates smoothly.
Also attaching a screenshot from the project that illustrates that pending functionality continues to work:
[Kazam_screencast_00006.webm](https://github.com/enso-org/enso/assets/292128/35918841-f84f-4e1c-b1b0-40e45d97e111)
Artifically limiting the number of reported warnings to 100. Also added benchmarks with random Ints to investigate perf issues when dealing with warnings (future task).
Ideally we would have a custom set-like collection that allows us internally to specify a maximal number of elements. But `EnsoHashMap` (and potentially `EnsoSet`) are still WIP when it comes to being PE-friendly.
The change also allows for checking if the limit for the number of reported warnings has been reached. It will visualize by adding an additional "Warnings limit reached." to the visualization.
The limit is configurable via `--warnings-limit` parameter to `run`.
Closes#6283.
Dead Letter logging is occasionally flooding our logs which is confusing to users reporting bugs. Left the possibility of a single report so that we know that something is happening.
During initialization JGit may attempt to resolve hostname. On some systems this can take more than desired triggering timeouts. This change does two things:
- sets the default committer for changes, lack of which probably triggered the check
- sets the default hostname to `localhost` (we don't care), in case something else in JGit still wants to resolve hostname
Closes#6447.

Changelog
- add: implement `SuggestionsRepo.insertAll` as a batch SQL insert
- update: `search/getSuggestionsDatabase` returns empty suggestions. Currently, the method is only used at startup and returns the empty response anyway because the libs are not loaded at that point.
- update: serialize only global (defined in the module scope) suggestions during the distribution building. There's no sense in storing the local library suggestions.
- update: sqlite dependency

When the project is renamed, the engine cleans up affected modules and initiates modules re-indexing to fill the suggestions database with new records. This way it reduces the amount of information stored in the suggestions database and helps implement #6080 optimization.
Changelog:
- remove: rename features from the suggestions database
- update: rename command to initiate modules cleanup and project re-execution
- fix: #6137
It is sometimes impossible to figure out the real reason for invalid text edit request. Added a bit of context to failures to narrow down the cause of the failure.

In interactive mode, perform writing IR caches in the background jobs queue. Background jobs execution is delayed until the first execution is complete.
The `logAvailableComponentsForDebugging` will check and install all necessary components of GraalVM for every mentioned version. While not harmful, it adds up to startup time.
Additionally added an option in language server startup to skip installation of GraalVM components. The latter is already performed by project-manager when opening the project and it is unnecessary to do it twice. Due to LS' architecture this configuration has to be passed around via multiple configs.
Finally, skipped the attempt to install Python component on Windows - this is not supported by GraalVM atm.
Closes#5749.
# Important Notes
The impact of this problem could be really felt the more versions of Enso and GraalVM one had since it would go through all of them.
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.

Changelog:
- Include the original exception to log expressions
- Enable logging of Akka Actors' lifecycle events on debug logging level
- Decrease the severity of interruption log messages because interruptions are part of the workflow. The computation can be interrupted at any time, and still be recomputed after. Warnings are just misleading in this case.
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.
Implements the #5643 idea. As soon as `MainModule` creates `Context` for GraalVM execution, it schedules a background task to initialize JavaScript. The initialization finishes sooner than Enso compiler is ready to work, saving time when it is actually needed.
# Important Notes
Only modifies boot sequence of `MainModule` (used in the IDE) and `VerifyJavaScriptIsAvailableTest` (to verify the _"context passing logic"_ works OK between threads). Regular CLI execution remains unchanged for now assuming batch execution may not need JavaScript in all the cases and if it does the initialization speed isn't that critical.
When the `project.yaml` specifies an unknown edition, the project is started with the fallback edition (current engine version). It works this way:
- IDE sends project/open request to project manager (specifying only which project to open)
- project manager resolves the project edition (based on `project.yaml`) or selects the fallback if the requested edition cannot be loaded
- project manager starts the language server specifying the edition with the `--server-edition` command line parameter
- language server specifies the correct edition when creates the runtime context
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.
Follow up on
16ba57d465 which marked the tests as flaky.
This test goes back to the original implementation where JGit did all its book-keeping synchronously. When we switched to asynchronous operation, cleaning up the test directory would sometimes not succeed because there would be a race-condition with the ongoing work of JGit.
# Important Notes
In the current setup tagging a test as flaky is only valid for Windows. The other platforms ignore the flag. So we were still getting random failures.
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.
Implementation of https://www.pivotaltracker.com/story/show/184012743https://user-images.githubusercontent.com/919491/214082311-cf49e43c-1d1f-4654-903c-a4224cd954d8.mp4
This is also a step towards more general widget support. The widget metadata is queried using `Meta.get_annotation` method through a dedicated visualization. For now only `Single_Choice` case is handled, and always all suggestions are is returned.
# Important Notes
There are limitations as to which node segments receive a widget. Only chain method calls are supported now (`thing.method` syntax), and only outside of lambda scope. Widgets in lambdas will require support for visualisations of lambda subexpressions, which is currently missing in the engine. The IDE technically tries to place the widgets there, but the data never arrives. It should work once the engine support is added.
This PR includes a mock for `Meta.get_annotation` call that only supports `Table.at` method. Real implementation is a separate task that is already in progress.
JGit ops generally run fast (as in a few milliseconds) except for the first commit. The initialization + first commit was taking at least 3.5 seconds constistenly, but only in the first test case. Now, this led to frequent timeouts down the chain when the request was expected to finish fast.
The bookkeeping involved some timestamping and other expensive calls in order to calculate clock drift. The default appears to be to run it in a blocking mode, hence adding at least 3 seconds to the first command call.
Setting the job to run in the background makes the cost of the repo initialization acceptable (~300 milliseconds on a cold JVM). The other commands are unaffected and take < 10 milliseconds.
# Important Notes
Added a test to ensure that we don't introduce the regression. Marked it as potentially flaky because it uses timestamps and it is therefore prone to random system hiccups.
There is no need for JGit to try to save file attributes to its config in `<home>/jgit/config`. This change ensures that JGit operates on a stub file, without polluting users' configs, similarly to user's git config.
Additionally, noticed that all FS operations during `init` are rather slow and saw at least on one occassion when the handler timed out because of that (https://www.pivotaltracker.com/story/show/184359934). This change provides an init-specific timeout for `vcs/init`.
# Important Notes
This change should reduce chances of failures during VCS initialization.
When a large long would be passed to a host call expecting a double, it would crash with a
```
Cannot convert '<some long>'(language: Java, type: java.lang.Long) to Java type 'double': Invalid or lossy primitive coercion
```
That is unlikely to be expected by users. It also came up in the Statistics examples during Sum. One could workaround it by forcing the conversion manually with `.to_decimal` but it is not a permanent solution.
Instead this change adds a custom type mapping from Long to Double that will do it behind the scenes with no user interaction. The mapping kicks in only for really large longs.
# Important Notes
Note that the _safe_ range is hardcoded in Truffle and it is not accessible in enso packages. Therefore a simple c&p for that max safe long value was necessary.
In order to investigate `engine/language-server` project, I need to be able to open its sources in IGV and NetBeans.
# Important Notes
By adding same Java source (this time `package-info.java`) and compiling with our Frgaal compiler the necessary `.enso-sources*` files are generated for `engine/language-server` and then the `enso4igv` plugin can open them and properly understand their compile settings.
In addition to that this PR enhances the _"logical view"_ presentation of the project by including all source roots found under `src/*/*`.
In the event when the action of the underlying actor crashes really bad, the result of the future will be `Failure`. All such results will be then wrapped in `Status.Failure` via `pipeTo` (unlike `Success` which just forwards the response).
In some cases we don't handle `Status.Failure` messages, meaning we are rather left in the dark to the reason of the failure with a non-informative message `Received unknown message: class akka.actor.Status$Failure`.
I'm keeping this change small on purpose to keep this change self-contained. I think there are more cases but it needs careful investigation into how messages are being sent.
# Important Notes
This PR does not attempt to fix the underlying problem of the ticket, yet. We should however have a better overview where/why things go wrong.
LS needs to notify runtime that modules' sources need to be reloaded from FS, once its own buffer has been reloaded as well.
# Important Notes
Discovered during integration of https://github.com/enso-org/enso/pull/4050.
The test illustrates the problem if we don't reload module's sources - the sources essentially become stale even though they have changed.
Unsetting literal sources during the `text/fileClose` operation would also unlink sources from the actual file. That would be never set back during the reopening of the file, resulting in an NPE during application of changes at a later point.
# Important Notes
Revealed during https://github.com/enso-org/enso/pull/4050 which was the first(?) to do close/open of the file.
The exception showing up in GUI and preventing further actions is now gone.
Potential workaround to line endings problems after `vcs/restore` operation is executed.
# Important Notes
Not really able to reproduce the problem myself so this PR has a lot of _leap of faith_ in it.
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.
Implements `getMetaObject` and related messages from Truffle interop for Enso values and types. Turns `Meta.is_a` into builtin and re-uses the same functionality.
# Important Notes
Adds `ValueGenerator` testing infrastructure to provide unified access to special Enso values and builtin types that can be reused by other tests, not just `MetaIsATest` and `MetaObjectTest`.
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.
The presence of `.git` in Enso's data directory (`.enso`), which should be under VCS as well, turned out to be really problematic. Git (and JGit) treat `.enso` as a submodule which prevents as from manual inspection of the repo. Additionally, every commit changed the submodule version, which in turn was reporting invalid/changed status always.
This change renames `.enso/.git` to `.enso/.vcs` which eliminates a lot of problems. Additionally, rather than doing `git add .` we selectively add files to the index, thus preventing most of the issues reported in the ticket.
This change also means that JGit's status needs to filter `.enso/.vcs` as those will be marked as untracked always.
# Important Notes
To manually test the status of the project's repo do
```
git --git-dir .enso/.vcs status
```
- Moved `Any`, `Error` and `Panic` to `Standard.Base`.
- Separated `Json` and `Range` extensions into own modules.
- Tidied `Case`, `Case_Sensitivity`, `Encoding`, `Matching`, `Regex_Matcher`, `Span`, `Text_Matcher`, `Text_Ordering` and `Text_Sub_Range` in `Standard.Base.Data.Text`.
- Tidied `Standard.Base.Data.Text.Extensions` and stopped it re-exporting anything.
- Tidied `Regex_Mode`. Renamed `Option` to `Regex_Option` and added type to export.
- Tidied up `Regex` space.
- Tidied up `Meta` space.
- Remove `Matching` from export.
- Moved `Standard.Base.Data.Boolean` to `Standard.Base.Boolean`.
# Important Notes
- Moved `to_json` and `to_default_visualization_data` from base types to extension methods.
Rather than hard-coding `.git` in the root of the project, VCS should save data into Enso's data directory (i.e. `.enso`).
This change reshuffles initialization and configuration to store Git VCS metadata by default at `.enso/.git`.
This is follow up to https://github.com/enso-org/enso/pull/3851
# Important Notes
Apparently a custom Git directory in JGit means that it always creates a `.git` **file** with `gitdir` pointing to the custom location.
This is not necessary in our case since all our commands provide that explicitly.
That is why `init` operation removes `.git` file, which may seem a bit counter-intuitive.
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.
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 change adds Autosave action for open buffers. The action is scheduled
after every edit request and is cancelled by every explicit save file request, if
necessary. Successful autosave also notifies any active clients of the buffer.

# Important Notes
WIP
PR allows to attach metod pointers as a visualization expressions. This way it allows to attach a runtime instrument that enables caching of intermediate expressions.
# Important Notes
ℹ️ API is backward compatible.
To attach the visualization with caching support, the same `executionContext/attachVisualisation` method is used, but `VisualisationConfig` message should contain the message pointer.
While `VisualisationConfiguration` message has changed, the language server accepts both new and old formats to keep visualisations working in IDE.
#### Old format
```json
{
"executionContextId": "UUID",
"visualisationModule": "local.Unnamed.Main",
"expression": "x -> x.to_text"
}
```
#### New format
```json
{
"executionContextId": "UUID",
"expression": {
"module": "local.Unnamed.Main",
"definedOnType": "local.Unnamed.Main",
"name": "encode"
}
}
```
