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.

- Implement disconnected edges and edge interactions (#7864).
- Port edge layout from Rust.
- Implement output ports, hover extensions, backward-edge arrows, hover-splitting.
# Important Notes
- A new `currentInteraction` API supports mutually-exclusive interactions; this is used to cancel edge creation when the CB is opened. We can use it more generally to ensure only one major interaction is ongoing at a time.
- Remaining details to reach parity with gui1 edges: #8139
`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.
Closes#8038.
After a discussion, I was really curious that our panics are supposed to be almost free - and while trusting that statement, it was really hard to believe - so I wanted to see for myself - knowing that an experiment is the most robust source of this kind of information - testing that in practice.
So I wrote a benchmark comparing various ways of reporting errors, also testing them both at 'shallow' and 'deep' stack traces (adding 200 additional frames) - to see how stack depth affects them, if at all.
The panics are indeed blazing fast! Kudos to the engine team. However, it seems that our dataflow errors are relatively slow (and we tend to use them _more_ than panics and want to be using them more and more). This uncovers a possible optimization opportunity. Can we make them as fast as panics??
Analysis of the benchmark results in comment below.
In order to execute `runtime-parser` in browser, we need to slightly simplify dependencies of our code.
# Important Notes
The actual PR explaining why these changes are desirable is #8094
Disables visual tests, because they are occasionally flaky (e.g. the recent issues with lint CI action).
This is very bad as it would cause every PR to (potentially) cause other PRs to fail, if the flaky test is not caught in the CI runs in the offending PR.
# Important Notes
None
- Fixes the issue that sometimes occurred on CI where old `services` configuration was not cleaned and SPI definitions were leaking between PRs, causing random failures:
```
❌ should allow selecting table rows based on a boolean column
An unexpected panic was thrown: java.util.ServiceConfigurationError: org.enso.base.file_format.FileFormatSPI: Provider org.enso.database.EnsoConnectionSPI not found
```
- The issue is fixed by detecting unknown SPI classes before the build, and if such classes are detected, cleaning the config and forcing a rebuild of the given library to ensure consistency of the service config.
- Closes https://github.com/enso-org/cloud-v2/issues/721
- Drag-n-drop for adding labels to an asset
- Adds to a single asset when hovering over an asset that is not selected
- Adds to all selected assets when hovering over an asset that is selected
### Important Notes
- The backend endpoint for associating labels with assets is currently broken - specifically, it errors when the new list of assets is empty.
- Fixes#8049
- Adds tests for handling of Date_Time upload/download in Postgres.
- Adds tests for edge cases of handling of Decimal and Binary types in Postgres.
close#8033
Changelog:
- update: run language server initialization once
- fix: issues with async `getSuggestionDatabase` message handling in new IDE
- update: implement unique background jobs
- refactor: initialization logic to Java
- refactor: `UniqueJob` to a marker interface
Improved warning reporting by not reporting IR in user-directed warning
messages. Made sure that fresh names retain some knowledge of the name
which they were created from.
Closes#7963.
- Closes#8062
# Important Notes
- This PR uses a completely separate implementation from the regexes used for the existing filtering. AFAICT, this is unavoidable, since this needs to retrieve matched text.
- I've come across a couple minor bugs related to the Component Browser:
- When deleting text (backspacing), the full list of unfiltered entries momentarily reappear because the filtering is reset.
- Things like `h.m` match `HTTP_Method` - if this is not intentional, it seems like it might be more difficult to fix, unfortunately.
- Note that highlighting (I assume correctly?) *does not* highlight any part of `HTTP_Method`.
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.
Implements #8025: `LazyObject` now has a `visitChildren` method that observes each direct-child `LazyObject`. `childrenAstNodes` is now a simple function that flattens non-Tree nodes out of the hierarchy; `validateSpans` visits both `Tree`s and `Token`s the same way we would use the `ItemVisitor` Rust API.
- Fixes issue with `to_display_text` on `Date_Time`. Now a reversible format.
- Adjusted the auto width code on table so it works.
- Manually sized columns should remain fixed size.
- Enable Excel range style selection in table.
- Removed page support as not implemented yet.
# Important Notes
Will need to apply to Vue based viz at some point as well.
`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
- Follow-up of #8055
- Adds a benchmark comparing performance of Enso Map and Java HashMap in two scenarios - _only incremental_ updates (like `Vector.distinct`) and _replacing_ updates (like keeping a counter for each key). These benchmarks can be used as a metric for #8090
- Closes https://github.com/enso-org/cloud-v2/issues/722
- Completely disables remote logging
# Important Notes
This is a temporary fix - GUI2 should have remote logging, but it may need a reimplemented entrypoint anyway.
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:
```

A recent PR introduced issues with circular imports in `categorySwitcher.ts` - the reason why this wasn't found before merge is because bundlers work fine with circular imports - it's just GUI2's dev mode that doesn't do well with them

# Important Notes
WIP: Use a color picker with pre-defined colors, instead of randomly generated colors
- Change imports from `'./'` relative imports to `@/` or `shared/` whenever possible
- Imports in `shared/` and `ydoc-server` have been avoided for now in case they don't work with `@/` imports.
- Deduplicate `events.ts`, remove `useDocumentEvent` in favor of `useEvent(document,` (and same for `useDocumentEventConditional`
- Replace incorrect doc comments (`//*` and `///`) with correct doc comments (`/**`)

- Closes#8041
- Integrates parser with CodeMirror
- Adds extensions builtin to CodeMirror
- Highlight text matching the selection
- Adds PoC CodeMirror extensions
- Basic syntax highlighting
- Code folding
- Hover tooltips
# Important Notes
As there is currently no way to get the corresponding node based on a position, the hover tooltip currently iterates through every node in `graphSotre.nodes`. This is potentially VERY SLOW and should be changed eventually, or disabled completely until an efficient implementation is possible.
SuggestionDb refactoring to facilitate documentation panel development and other features.
Now SuggestionDb uses `ReactiveDb` + `ReactiveIndex`es under the hood. There are no visual changes to the IDE. Everything still works the same.
You can now use two reactive indexes built on top of the SuggestionDb:
1. `db.nameToId` is a `QualifiedName→SuggestionId` relation. Reverse lookup allows you to get the qualified name by ID.
2. `db.parent` is a `SuggestionId→SuggestionId` relation, representing parent-children relations between entries. The rules are the following:
- If the `memberOf` field is present, it is used as a parent.
- Otherwise, a parent’s qualified name is used (through the `qnParent` function)
You can use reverse lookup to get the children of the entry.
You can easily add your own indexes if needed.
- Closes https://github.com/enso-org/cloud-v2/issues/697
- Adds infrastructure to support drag-and-drop
- Implements drag-and-drop for deleting and undeleting assets
- Implements drag-and-drop for moving assets to a new directory (or the root directory)
- Also implements "cut" and "paste" context menu actions (and keyboard shortcuts) using the new endpoint for moving files
- "Copy" and "duplicate" actions are *not* implemented, as I don't think there are backend endpoints for those yet.
- Fades items out when cutting (Cmd+X), fades them back in when cancelling (Esc)
- Fixes bug where keyboard shortcut handlers were not registered for table-wide shortcuts (delete all, restore all, cut all)
# Important Notes
Drag-and-drop for more situations are planned but intentionally not yet implemented:
- Labels (backend is WIP, and blocked on the corresponding frontend PR)
- Moving assets between folders (backend functionality does not yet exist)
