A long running initialization of the component blocks the execution significantly. Removed the `BlockingInitialization` and replaced it with a more fine grained locking.
# Important Notes
Added a simple workaround for potential slow initialization of backend - more retries. We should have a better UX in that case anyway, but due to absence of work on that in old GUI, this will have to do.
The main should be problem should be addressed already by other backend changes. Changes in `app` should only be treated as _just in case something bad happens_.
* OpenFileCmd sends a reply when finished
Lack of reply and therefore a non-determinism on when OpenFile handler
can finish, led to some sporadic instability. Once caches format got
changed, things were taking such a long time that I wasn't able to start
even a basic project (requests would start to timeout).
The change also removes PushContextCmd from synchronous cmds (as
introduced in #798 to remove initialization problems in tests as well as
in real scenarions); the change did the job but was also a bit
controversial.
The change can also help with randomly failing applies (#8174) as IDE kept
closing and opening the project that might have exploited the
race-condition.
* Adapt tests
* Make tests more resilient to out of order messages
* Drop retries that lead to confusing errors
* less random failures

Debugging the issue reported by @PabloBuchu when the language server initialization hangs in the cloud. I'm still not sure what is happening in the cloud because I was not able to reproduce it when trying to connect two clients simultaneously.
Another potential source of the issue may be the Scala Future -> Java CompletableFuture conversion, but I didn't find anything suspicious there.
The change upgrades `directory-watcher` library, hoping that it will fix the problem reported in #7695 (there has been a number of bug fixes in MacOS listener since then).
Once upgraded, tests in `WatcherAdapterSpec` because the logic that attempted to ensure the proper initialization order in the test using semaphore was wrong. Now starting the watcher using `watchAsync` which only returns the future when the watcher successfully registers for paths. Ideally authors of the library would make the registration bit public
(3218d68a84/core/src/main/java/io/methvin/watcher/DirectoryWatcher.java (L229C7-L229C20)) but it is the best we can do so far.
Had to adapt to the new API in PathWatcher as well, ensuring the right order of initialization.
Should fix#7695.
Fixes#8186 by turning `IllegalStateException` into log message. Re-assigning of `BindingsMap` can happen in the IDE where evaluation of modules is repeated again and again. In addition to that avoid dropping errors in compiler without them being noticed.
Using a `TruffleLogger` in `SerializationManager` that is bound to the engine rather than the context prevents reaching an illegal state when using thread pools.
Also cleaned up some tests for consistency.

Closes#8147.
The change eliminates a race-condition that can appear between the `PathWatcher` deregistering the last client (and shutting down) and `ReceivesTreeUpdatesHandler` receiving the termination message of that event. In between there could come a message towards the mentioned `PathWatcher` resulting in a timeout.
The scenario has become rather common in CI tests resulting in spurious failures. The problem could also be simulated by adding artificial `Thread.sleep` between sending the reply in `PathWatcher` and stopping the actor.
Fixes#8151.

Towards reduced reliance on Scala semantics.
Translated IR.scala to IR.java and extracted implicits that now need to be imported explicitly.
# Important Notes
1:1 translation. For now `@Identifier` and `@ExternalID` represent the old type aliases but are not verified at compile time.
This is because in a mixed Scala/Java world this seems impossible to employ such frameworks as Checker.
`capability/acquire` with an invalid method `executionContext/canModify` would previously timeout because the capability router simply didn't support that kind of capability request.
Now rather than timing out, indicating a failure on LS, we report an error.

Unmasked position info for the failed edits so that it is possible to understand what edits are attempted at all. So far unable to locate the problem based solely on the logs and the stacktrace. Added a test confirming that making edits at the end of the file continues to be fine (that's where the problem usually manifests itself).
# Important Notes
References #7978
- Validate spans during existing lexer and parser unit tests, and in `enso_parser_debug`.
- Fix lost span info causing failures of updated tests.
# Important Notes
- [x] Output of `parse_all_enso_files.sh` is unchanged since before #7881 (modulo libs changes since then).
- When the parser encounters an input with the first line indented, it now creates a sub-block for lines at than indent level, and emits a syntax error (every indented block must have a parent).
- When the parser encounters a number with a base but no digits (e.g. `0x`), it now emits a `Number` with `None` in the digits field rather than a 0-length digits token.
`AmbgiuousImport` error and `DuplicatedImport` warning must not have `Source` as one of its fields or compiler will crash during a serialization attempt.
Changed the implementation to provide it as a parameter to the `message` method instead.
Fixes#8089
Having a modest-size files in a project would lead to a timeout when the project was first initialized. This became apparent when testing delivered `.enso-project` files with some data files. After some digging there was a bug in JGit
(https://bugs.eclipse.org/bugs/show_bug.cgi?id=494323) which meant that adding such files was really slow. The implemented fix is not on by default but even with `--renormalization` turned off I did not see improvement.
In the end it didn't make sense to add `data` directory to our version control, or any other files than those in `src` or some meta files in `.enso`. Not including such files eliminates first-use initialization problems.
# Important Notes
To test, pick an existing Enso project with some data files in it (> 100MB) and remove `.enso/.vcs` directory. Previously it would timeout on first try (and work in successive runs). Now it works even on the first try.
The crash:

* Reduce extra output in compilation and tests
I couldn't stand the amount of extra output that we got when compiling
a clean project and when executing regular tests. We should strive to
keep output clean and not print anything additional to stdout/stderr.
* Getting rid of explicit setup by service loading
In order for SL4J to use service loading correctly had to upgrade to
latest slf4j. Unfortunately `TestLogProvider` which essentially
delegates to `logback` provider will lead to spurious ambiguous warnings
on multiple providers. In order to dictate which one to use and
therefore eliminate the warnings we can use the `slf4j.provider` env
var, which is only available in slf4j 2.x.
Now, there is no need to explicitly call `LoggerSetup.get().setup()` as
that is being called during service setup.

ConsoleHandler's constructor uses `Level.INFO` which is unnecessary for

Warnings

It seems that Runtime Connector wasn't respecting the protocol it defined itself. The connector should be waiting on the `Api.InitializedNotification` message and only then start forwarding messages. So far it seems this hasn't been a problem, or at least wasn't reported as such, because initialization was fast enough.
Modified `Handler` so that we are certain that its fields hold initialized values when being accessed by different threads.
Should fix problems mentioned in #7898.
* 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

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.

# 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.
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.

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
- Closes#7461 by introducing a `Date_Time_Formatter` type and making parsing date time formats more robust and safer.
- The default ('simple') set of patterns is slightly simplified and made case insensitive (except for `M/m` and `H/h`) to avoid the `YYYY` vs `yyyy` issues and make it less error prone.
- The `YYYY` now has the same meaning as `yyyy` in simple mode. The old meaning (week-based year) is moved to a _separate mode_, triggered by `Date_Time_Formatter.from_iso_week_date_pattern`.
- Full Java syntax, as well as custom-built Java `DateTimeFormatter` can also be used by `Date_Time_Formatter.from_java`.
- Text-based constants (e.g. `ISO_ZONED_DATE_TIME`) have now become methods on `Date_Time_Formatter`, e.g. `Date_Time_Formatter.iso_zoned_date_time`).
* 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.

- Added directory listing to `Auto_Detect` allowing for `Data.read` to list a folder.
- Adjusted HTTP to return an `InputStream` not a `byte[]`:
- `Response_Body` adjusted to wrap an `InputStream`.
- Added ability to materialize to either and in-memory vector (<4KB) or a temporary file.
- `Data.fetch` will materialize if not a recognized mime-type.
- Added `HTTP_Error` to handle IO exceptions from the stream.
- `Excel_Format` now supports mime-type and reading a stream.
- `Excel_Workbook` can now get a `Excel_Section` using `read_section`.
- Added S3 APIs:

- `list_objects`: list the items in a S3 bucket with specified prefix.
- `read_bucket`: list prefixes and keys with a delimiter in a S3 bucket with specified prefix.
- `head`: either head_bucket (tests existance) or head_object API (reads object meta data).
- `get_object`: gets an object from S3 returning as a `Response_Body`.
- Added `S3_File` type acting like a `File`:
- No support for writing in this PR.
- **ToDo:** recursive listing, glob filtering, exists, size.
- Fixed a few invalid type signature line.
- Moved `create` methods for `Postgres_Connection` and `SQLite_Connection` into type instead of module.
- Renamed `Column_Fetcher.Builder` to `Column_Fetcher_Builder`.
- Fixed bug with `select_into` in Dry Run mode creating permanent tables.
**ToDo:** Unit tests.
Closes#7677 by eliminating the _stackoverflow execption_. In general it seems _too adventurous_ to walk members of random foreign objects. There can be anything including cycles. Rather than trying to be too smart in these cases, let's just rely on `InteropLibrary.isIdentical` message.
# Important Notes
Calling `sort` on the `numpy` array no longer yields an error, but the array isn't sorted - that needs a fix on the Python side: https://github.com/oracle/graalpython/issues/354 - once it is in, the elements will be treated as numbers and the sorting happens automatically (without any changes in Enso code).

This PR addresses two problems mentioned in #7766:
1. A random integer overflow, likely caused by a bug in Rust parser
2. A concurrent access to a methods' map
Re 1: Unable to reproduce but it doesn't mean it won't happen again. Added a try/catch to get in the logs source code that caused it **and** not crash hard when it occurs.
Re 2: Changing methods map from `HashMap` to `ConcurrentHashMap`. Due to a poor design we leaked the underlying structure in a number of places, unnecessairly. `ConcurrentHashMap` does not accept `null` keys therefore due to leaking implementation had to ensure that `methods` of `ModuleScope` never escapes as-is.
Both workarounds should ensure that we don't crash hard when they appear.
Closes#7766
- Closes#7238
- Aligns `update_database_table` to a more consistent and clearer API - `update_rows`.
- Adds a `truncate_table` helper function, to pair up with `drop_table`. Both are `PRIVATE` for now.
- Adds tests for NULLs in keys in `update_rows` and `delete_rows`.
- The behaviour is sometimes unexpected, so instead these fail with `Null_Values_In_Key_Columns`.
- Adds a workaround for https://github.com/oracle/graal/issues/7359
- Adds a workaround for a related bug where a stack frame has no name (its `rootNode.getName() == null`).
- I could not track down this bug to provide a neat repro.
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`.

Addresses:

- 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**.

While investigating behavior of
```
sbt:std-benchmarks> withDebug benchOnly --dumpGraphs -- Vector_Operations.Max_Stat
```
in IGV I realized there is a deep chain of nodes when reading an element of `Vector` related to work with warnings. There is an invocation of `WarningsLibrary` on `this` - that's probably unnecessary as we know how it is going to resolve. This PR skips such one level of indirection by directly delegating to `this.storage`.
However I haven't seen any effect of this change on peak performance. The library overhead seems to disappear. Anyway I wanted to bring this finding to your attention and perform independent measurement on our CI server.
MethodProcessor generates code for builtin method invocation that is wrapped in `try-catch` and handles some predefined subset of `RuntimeException`. So far, only `com.oracle.truffle.dsl.api.UnsupportedSpecializationException`.

Added a guard to prevent us from sending expression updates when dealing with nulls.
Fixes#7213 by reacting to new `isBigInteger` and `asBigInteger` messages. Adjusts tests to require `BigInteger` when appropriate. `EnsoBigInteger` no longer extends `Number`. Enso tests to come.
- Closes#5951
- Ensures any SQL warnings reported by the database through the JDBC driver are processed and forwarded to the user.
- These warnings show issues like the implicit name truncation that this PR is also solving. It's good to make sure they are visible as they can help avoid and understand unexpected problems. They should not show up in most standard workflows.
- Adds simple history to our REPL.
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

Fixes#7279 by detecting missing `getClose()` and yielding an `UnclosedTextLiteral`.
# Important Notes
Special care must be taken for _text blocks_. They have `null` `getClose()`.
- Previous GraalVM update: https://github.com/enso-org/enso/pull/6750
Removed warnings:
- Remove deprecated `ConditionProfile.createCountingProfile()`.
- Add `@Shared` to some `@Cached` parameters (Truffle now emits warnings about potential `@Share` usage).
- Specialization method names should not start with execute
- Add limit attribute to some specialization methods
- Add `@NeverDefault` for some cached initializer expressions
- Add `@Idempotent` or `@NonIdempotent` where appropriate
BigInteger and potential Node inlining are tracked in follow-up issues.

R component was dropped from the release 23.0.0, only `python` is available to install via `gu install python`.
This PR does three related things:
- Fails more gracefully when a non-string is passed to compile_regex
- Don't pass a non-string to compile_regex
- Allow a Regex param to parse_to_table
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.
This PR modifies the builtin method processor such that it forbids arrays of non-primitive and non-guest objects in builtin methods. And provides a proper implementation for the builtin methods in `EnsoFile`.
- Remove last `to_array` calls from `File.enso`
Less dependencies on `EnsoContext` - `Module` shall exist without it. `Module` is a result of a `Compiler` and shall be created before its execution - e.g. requiring `EnsoContext` (with all its runtime information) is a bit too _demanding_.
# Important Notes
The only reason why `Module` wanted `EnsoContext` was to create its (associated) `Type`. `Type`'s constructor needed a parent type and the code was asking for `Any` from the context. That's unnecessary at creation time - we can just use some constant (like `null`) and turning it into `Any` during execution. Benchmarks show that there is no slowdown doing so.
On a quest to avoid dependencies on `EnsoContext` from `Compiler`. Step one. The ultimate goal is to move `Compiler` and all its `IRPasses` into a dedicated `runtime/compiler` module that could be used from #7054.
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
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):
- Removed Array methods: `new`, `copy` and `new_[1234]`.
- New builtins for `Vector.insert`, `Vector.remove` and `Vector.flatten`.
- Replaced `Vector_Builder` use of `Array.copy` to a `Vector.Builder` approach.
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.
Mostly stuff to tidy up the static methods in the CB.
- Remove default pattern from `parse_to_table` (caused IDE to freeze).
- Rename any `_` arguments to what they are.
- Merge `Date.now` into `Date.today`
- Merge the Interval constructors into a single constructor.
- Hide various methods.
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)
Partially revert https://github.com/enso-org/enso/pull/6849, which introduced a regression in TCO in the presence of warnings. Rather than modifying the tail call status, `TailCallException` now propagates the extracted warnings and appends them to the final result.
Closes#7093
# Important Notes
Compared to the previous attempt we don't pay the penalty of adding the warnings or even checking for them because it is being dealt in a separate specialization.
Function bodies cannot be instrumented even if the function is right
inside a binding. Consider a scenario when a function is assigned to a
variable and then applied to a `map` method of a really large vector.
The instrumentation will render execution extremely slow.
Alternatively we would still support instrumenting function bodies in
this limited case but take into account the number of times function is
actually called.
Previously, static method calls on `Any` have not worked as expected. For example, `Any.to_text` returned Function instead of Text. That is because the function resolution for `Any.to_text` finds `Any.type.to_text` method on eigentype which expects two `self` arguments, but only one argument is provided.
Note that `Boolean.to_text` worked previously, and returned "Boolean" as expected. This is because the method resolution finds `Any.to_text` method that takes just one `self` argument.
This PR solves this issue by introducing special handling for static method dispatch on `Any`. Simply put, an additional `self` argument is prepended to the argument list.
# Important Notes
A new child node is introduced to `InvokeMethodNode`. This child node is a copy of the current `invokeFunctionNode` with one more `CallArgumentInfo` in its schema.
There is an issue that after a clean build, the compiler is unable to resolve some types, i.e

The compiler can't resolve those symbols because the `IR` cache for `Standard.Database.Connection.Database` is missing. What happens during the `buildEngineDistribution` is:
- Compiler processes libraries one by one
- Compiler processes (and compiles and generates caches) `Standard.Database` library
- Compiler starts processing `Standard.Visualization` library
- During the compilation of `Standard.Database.Connection.Database` module, it sees that the module was loaded from the cache. But some of the required dependencies from `Standard.Table` library were not loaded from the cache. But at this point, the `Standard.Table` library has not been processed yet and the caches for it don't exist. The compiler decides that the `Database` file was changed, and the cache is invalid and should be cleaned.
- Removed `module` argument from `enso_project` (new `Project_Description.new` API).
- Removed the custom option from date and time parse/format dropdowns.
- The `format` dropdown uses the value to create the dropdown. (Screenshot below)
- Removed `StorageType` coalescing rules and replaced them with simpler logic in `ObjectStorage`.
- Update signature for `add_row_number` and add aliases.
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.

There was an inherent race condition between edit, close & open commands which could not be prevented solely using locks. `EditFileCmd` triggered `EnsureCompiledJob` which was applying edits collected over time. At the same `CloseFileCmd` and `OpenFileCmd` were executed asynchronously and required locks on compilation unit and file lock.
Additionally, open file was resetting the module's runtime source irrespective of any edits that could already have been applied with the asynchronous execution in `EnsureCompiledJob`. This was visible especially during early manipulation of the project when open/close was performed due to a bug in IDE (#6843).
Now commands can be run either synchronously or asynchronously. Only that way can we ensure that `close` & `open` commands finish by the time any editions are being applied to module's sources.
Closes#6841.
# Important Notes
In the given video, `"foo"` would be greyed out because it would never be part of the module's (runtime) sources. Therefore no IR would be generated for it or instrumentation, meaning it would be present in `expressionUpdates` information necessary for IDE.
[Kazam_screencast_00014.webm](https://github.com/enso-org/enso/assets/292128/226a17b8-729a-415a-803f-003a9695b2f1)
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.
