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.

close#6900
This is a follow-up to the discussion of the imports/exports meeting.
Right now we have no control over the visibility of atom constructor arguments. One way to hide them is a convention of filtering getters by an `internal` prefix or suffix.
Related to #6912
It essentially solves it by removing any builtins that would take an EnsoDate/EnsoTimeOfDay/EnsoTimeZone and replacing them with Java utils that do the same operation.
This is not a proper solution - the builtin conversion is still invalid for the date/time types - but at this moment we may just no longer use the invalid conversion so it is much less of an issue. We still need to be aware of this if we want to introduce builtins taking date/time in the future.
At the beginning of the execution `EnsureCompiledJob` acquired write compilation lock. When compiling individual modules it would then
- acquire file lock
- acquire read compilation lock
The second one was spurious since it already kept the write lock. This sequence meant however that `CloseFileCmd` or `OpenFileCmd` can lead to a deadlock when requests come in close succession. This is because commands:
- acquire file lock
- acquire read compilation lock
So `EnsureCompiledJob` might have the (write) compilation lock but the commands could have file lock. And the second required lock for either the job or the command could never be acquired.
Flipping the order did the trick.
Partially solves #6841.
# Important Notes
For some reason we don't get updates for the newly added node, as illustrated in the screenshot, but that could be related to the close/open action. Will need to dig more.
Previously, a `RuntimeException` would be thrown when an attempt would be made to curry a conversion function. That is problematic for IDE where `executionFailed` means we can't enter functions due to lack of method pointers info.
Closes#6897.
# Important Notes
A more generic solution that allows to recover from execution failures will need a follow up.
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.
Throwing `TailCallException` meant that exceptions that were extracted from the expression before the call was made could not be appended. This change catches the `TailCallException`, adds warnings to it and propagates it further, thus ensuring that we don't loose the information.
Closes#6765.
# Important Notes
Removed workarounds introduced in stdlib.
Add diagnosis for unresolved symbols in `from ... import sym1, sym2, ...` statements.
- Adds a new compiler pass, `ImportSymbolAnalysis`, that checks these statements and iterates through the symbols and checks if all the symbols can be resolved.
- Works with `BindingsMap` metadata.
- Add `ImportExportTest` that creates various modules with various imports/exports and checks their generated `BindingMap`.

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.

Changelog:
- update: run compiler passes on the `ascribedType` field of the constructor arguments
- update: suggestion builder uses the type information attached to `ascribedType`
- feat: resolve qualified names in type signatures
Related to #6410
# Important Notes
- Updated some `Meta` methods (needed for error handling):
- `Meta.Type` now has `name` and `qualified_name`.
- `Meta.Constructor` has `declaring_type` allowing to get the type that this constructor is associated with.
Fixes#6609 by
- e380e647af - running whole `Vector_Spec` on `java.util.ArrayList`
- 9b1229fe20 - introducing a node to handle interop values
# Important Notes
Contains additional DSL processor fix:
- 415623dcb9 - to not crash the compiler, but to properly report compiler error
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.
Add format to the in-memory Column
# Important Notes
Also updates .format in date types.
Some rearrangement of date formatting builtins / Java libraries.
Engine Benchmark job runs only engine benchmarks, not Enso benchmarks.
Enso benchmarks do not report their output anywhere, and take more than 5 hours to run nowadays.
We might define a new job in the future and probably rename it to "Library benchmarks".
But that is the responsibility of the lib team.
Deeply nested modules (of depth at least 3) would have the incorrect name inferred for synthetic modules. This also became apparent in a much bigger rewrite.
Instead of having module `A.B.C`, as described in the test, it would infer the name to be `B.A.C`, which would break when trying to reference symbols from `C`.
# Important Notes
No ticket reference, as this was something that @radeusgd discovered while working on another component.
The PR includes a minimal example that would previously fail to compile.
Remove the magical code generation of `enso_project` method from codegen phase and reimplement it as a proper builtin method.
The old behavior of `enso_project` was special, and violated the language semantics (regarding the `self` argument):
- It was implicitly declared in every module, so it could be called without a self argument.
- It can be called with explicit module as self argument, e.g. `Base.enso_project`, or `Visualizations.enso_project`.
Let's avoid implicit methods on modules and let's be explicit. Let's reimplement the `enso_project` as a builtin method. To comply with the language semantics, we will have to change the signature a bit:
- `enso_project` is a static method in the `Standard.Base.Meta.Enso_Project` module.
- It takes an optional `project` argument (instead of taking it as an explicit self argument).
Having the `enso_project` defined as a (shadowed) builtin method, we will automatically have suggestions created for it.
# Important Notes
- Truffle nodes are no longer generated in codegen phase for the `enso_project` method. It is a standard builtin now.
- The minimal import to use `enso_project` is now `from Standard.Base.Meta.Enso_Project import enso_project`.
- Tested implicitly by `org.enso.compiler.ExecCompilerTest#testInvalidEnsoProjectRef`.
close#6324
Changelog
- feat: DataflowAnalysis compiler pass preserves the order of dependencies. This way when attaching the visualization to the sub-expression, the engine can find the first cached parent node, and properly invalidate it.
- update: runtime visualization test is updated to reproduce the issue
# Important Notes
The dropdown for the column `"LOCATION"` is available right after the Restaurants project startup.
There is 572 threads during `RuntimeServerTest` execution create. They stay around because the context isn't closed after each test finishes. Adding `afterEach` cleanup sequence to `runtime-with-instruments` tests. Improving robustness of overall `EnsoContext` [shutdown](https://github.com/enso-org/enso/pull/6468#discussion_r1180348303).
- Adjusted `Context.is_enabled` to support default argument (moved built in so can have defaults).
- Made `environment` case-insensitive.
- Bug fix for play button.
- Short hand to execute within an enabled context.
- Forbid file writing if the Output context is disabled with a `Forbidden_Operation` error.
- Add temporary file support via `File.create_temporary_file` which is deleted on exit of JVM.
- Execution Context first pass in `Text.write`.
- Added dry run warning.
- Writes to a temporary file if disabled.
- Created a `DryRunFileManager` which will create and manage the temporary files.
- Added `format` dropdown to `File.read` and `Data.read`.
- Renamed `JSON_File` to `JSON_Format` to be consistent.
(still to unit test).
Fixes#6416 by introducing `InlineableNode`. It runs fast even on GraalVM CE, fixes ([forever broken](https://github.com/enso-org/enso/pull/6442#discussion_r1178782635)) `Debug.eval` with `<|` and [removes discouraged subclassing](https://github.com/enso-org/enso/pull/6442#discussion_r1178778968) of `DirectCallNode`. Introduces `@BuiltinMethod.needsFrame` - something that was requested by #6293. Just in this PR the attribute is optional - its implicit value continues to be derived from `VirtualFrame` presence/absence in the builtin method argument list. A lot of methods had to be modified to pass the `VirtualFrame` parameter along to propagate it where needed.
This change modifies method dispatch for methods that override Any's definitions. When an overrided method is invoked statically we call Any's method to stay consistent.
This change primarily addresses the plethora of problems related to `to_text` invocations. It does not attempt to completely modify method dispatch logic.
Closes#6300.

related #6323
The engine can skip compilation when applying changes that do not require execution. It is more efficient to process the changes in a batch, than triggering compilations every time such edit is received.
While Enso runs single-threaded, its `ResourceManager` required additional asynchronous thread to execute its _"finalizers"_. What has been necessary back then is no longer needed since _GraalVM 21.1_. GraalVM now provides support for submitting `ThreadLocalAction` that gets then picked and executed via `TruffleSafepoint` locations. This PR uses such mechanism to _"inject"_ finalizer execution into already running Enso evaluation thread.
Requiring more than one thread has complicated Enso's co-existence with other Truffle language. For example Graal.js is strictly singlethreaded and used to refuse (simple) co-existence with Enso. By allowing Enso to perform all its actions in a single thread, the synergy with Graal.js becomes better.
`Number.nan` can be used as a key in `Map`. This PR basically implements the support for [JavaScript's Same Value Zero Equality](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Equality_comparisons_and_sameness#same-value-zero_equality) so that `Number.nan` can be used as a key in `Map`.
# Important Notes
- For NaN, it holds that `Meta.is_same_object Number.nan Number.nan`, and `Number.nan != Number.nan` - inspired by JS spec.
- `Meta.is_same_object x y` implies `Any.== x y`, except for `Number.nan`.
`Vector.sort` does some custom method dispatch logic which always expected a function as `by` and `on` arguments. At the same time, `UnresolvedSymbol` is treated like a (to be resolved) `Function` and under normal circumstances there would be no difference between `_.foo` and `.foo` provided as arguments.
Rather than adding an additional phase that does some form of eta-expansion, to accomodate for this custom dispatch, this change only fixes the problem locally. We accept `Function` and `UnresolvedSymbol` and perform the resolution on the fly. Ideally, we would have a specialization on the latter but again, it would be dependent on the contents of the `Vector` so unclear if that is better.
Closes#6276,
# Important Notes
There was a suggestion to somehow modify our codegen to accomodate for this scenario but I went against it. In fact a lot of name literals have `isMethod` flag and that information is used in the passes but it should not control how (late) codegen is done. If we were to make this more generic, I would suggest maybe to add separate eta-expansion pass. But it could affect other things and could be potentially a significant change with limited potential initially, so potential future work item.
https://github.com/orgs/enso-org/discussions/6344 requested to change the order of arguments when controlling context permissions.

The change brings it closer to the design doc but IMHO also a bit cumbersome to use (see changed tests) - applications involving default arguments don't play well when the last argument is not the default 🤷 .`

The primary motivation for this change was
https://github.com/enso-org/enso/issues/6248, which requested the possibility of defining `to_display_text` methods of common errors via regular method definitions. Until now one could only define them via builtins.
To be able to support that, polyglot invocation had to report `to_display_text` in the list of (invokable) members, which it didn't. Until now, it only considered fields of constructors and builtin methods. That is now fixed as indicated by the change in `Atom`.
Closes#6248.
# Important Notes
Once most of builtins have been translated to regular Enso code, it became apparent how the usage of `.` at the end of the message is not consistent and inflexible. The pure message should never follow with a dot or it makes it impossible to pretty print consistently for the purpose of error reporting. Otherwise we regularly end up with errors ending with `..` or worse. So I went medieval on the reasons for failures and removed all the dots.
The overall result is mostly the same except now we are much more consistent.
Finally, there was a bit of a good reason for using builtins as it simplified our testing.
Take for example `No_Such_Method.Error`. If we do not import `Errors.Common` module we only rely on builtin error types. The type obviously has the constructor but it **does not have** `to_display_text` in scope; the latter is no longer a builtin method but a regular method. This is not really a problem for users who will always import stdlib but our tests often don't. Hence the number of changes and sometimes lack of human-readable errors there.

As per design, IOContexts controlled via type signatures are going away. They are replaced by explicit `Context.if_enabled` runtime checks that will be added to particular method implementations.
`production`/`development` `IOPermissions` are replaced with `live` and `design` execution enviornment. Currently, the `live` env has a hardcoded list of allowed contexts i.e. `Input` and `Output`.

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: sqlite dependency
- remove: unused methods from `SuggestionsRepo`

# Important Notes
Speeds up libraries loading by ~1 second.
Implements #6134.
# Important Notes
One can define lazy atom fields as:
```haskell
type Lazy
Value ~x ~y
```
the evaluation of the `x` and `y` fields is then delayed until they are needed. The evaluation happens once. Then the computed value is kept in the atom for further use.
Fixes#5898 by removing `Catch.panic` and speeding the `sieve.enso` benchmark from 1058 ms to 514 ms. Should there be no dedicated conversion, let's use one defined on `Any` type - e.g. defining a conversion `from(Any)` makes such a conversion is always available.
Delay creation of `EnsoFile` until it is needed.
# Important Notes
By putting breakpoint into `Atom` constructor I realized few `EnsoProjectNode` instances may be created when parsing the project. It makes no sense to also create `EnsoFile` for them - until it is needed.
Modification to various tests disabled when #5917 was integrated to pass with new parser. Fixes#5894.
# Important Notes
Some tests can be fixed just by changes on the `IR` side. Some (especially error simulating ones) would benefit from changes in the `Tree` structure or at least @kazcw evaluation.

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
`--compile` command would run the compilation pipeline but silently omit any encountered errors, thus skipping the serialization. This maybe was a good idea in the past but it was problematic now that we generate indexes on build time.
This resulted in rather obscure errors (#6092) for modules that were missing their caches.
The change should significantly improve developers' experience when working on stdlib.
# Important Notes
Making compilation more resilient to sudden cache misses is a separate item to be worked on.
The primary delivery of this PR is a design of `SerdeCompilerTest` - a testing suite that allows us to write sample projects, parse them with and without caches and verify they still produce the same `IR`. This is a similar idea to #3723 which compared the old and new parser `IR`s.
With infrastructure like this we can start addressing #5567 without any (significant) fear of breaking something essential.
Treat `Boolean.False` and `Boolean.True` as the corresponding primitives. Now, `Boolean.False == False` returns true.
# Important Notes
`False` and `True` constructs, that are converted to `ConstructorNode` during Truffle codegen, are handled specially in `ConstructorNode`. The easiest fix was to implement a similar special handling in `QualifiedAccessorNode`, although not the cleanest one.
A better solution would be to provide transformation of `Boolean.True` IR to a true literal in `ApplicationSaturation` compiler pass. But `ApplicationSaturation` pass does not handle `True`. Moreover, for our case, it is unnecessarily complicated.
Instrumentation of calls involving warning values never really worked because:
1) newly created nodes didn't set the UUID of their children
2) the instrumentable wrappers always had an empty (i.e. null) UUID and
they never referred `get`/`setId` calls to their delegates
On the surface, everything worked fine. Except when one actually relied on the instrumentation of values with warnings for proper setup. Then no instrumentation (replacement of nodes) was performed due to empty UUID (as required by `hasTag` of `FunctionCallInstrumentationNode`).
Closes#6045. Discovered in #5893.
