It looks like visualization commands had required context lock unnecessairly. Context manager methods are synchronized and therefore should not need the lock before submitting a correspodning background job.
Additionally, the presence of a context lock leads a deadlock:
1. Consider a long running execution of a program that does not finish within the 5 seconds
2. In the meantime there comes either an `AttachVisualization` or `DetachVisualization` request from the client
The latter will get stuck and eventually timeout out because it cannot acquire the lock withing the required time limits. It is still possible that a single long-running `ExecuteJob` might block other ones (including visualization ones) but that's a separate work.
Fixes some issues present in #7941.
# Important Notes
We need to still investigate `ExecuteJob`s need for context lock which might delay the execution of other background jobs that require it as well (mostly concerned about visualization).
* Q: Is it normal for `--inspect` mode to print two debug urls?
* A: No, it should print just one.
* Q: Putting there a Java breakpoint to find out why it the chromeinspector gets initialized twice might reveal the culprit.
* A: The additional listener is happening [here](https://github.com/enso-org/enso/blob/develop/engine/runner/src/main/scala/org/enso/runner/ContextFactory.scala#L117).
# Important Notes
There is no easy check for a language being present without creating an `Engine`. It was thought creating an `Engine` is cheap operation, but it seems to have some downsides. Let's use `ENSO_JAVA` environment variable to decide whether _experimental Espresso_ support shall be enabled.
* 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.

Changelog:
- update: project manager uses the packaged language server to open projects
- fix: remove stack traces from connection errors on initial ping handler request (when the language server is booting)
- update: add engine and edition versions to the `initProtocolConnection` response for easier debug
- update: do not resolve project ensoVersion in the `project/list` to eliminate unnecessary network calls
* 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:
- 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`.
# 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**.

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.

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.
