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.
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 a `FileSystemSPI` allowing protocol resolution to a target type.
- Separated `Input_Stream` and `Output_Stream` from `File` to allow use in other spaces.
- `File_Format` types `read_web` changed to be `read_stream` working with `InputStream`.
- 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:
- `parse_uri`: splits an S3 URI into bucket and key.
- `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).

Changelog:
- update: send the ok response before the notification to fix the order of events in tests
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.
