Serialize document open/release with change delivery.
dispatchDocumentOpenEvent() replaces FileManager's ActiveDocument at version 0, while a queued change can still be stamped and dispatched. FileManager.onDocumentContentChange() then accepts that stale version, and ActiveDocument.update() rejects subsequent new-session versions until they exceed it. Add a generation token or serialize open/release with change dispatch, and drop stale changes.

io.github.Rosemoe.sora-editor 0.23.6 ContentChangeEvent source changedText changeStart changeEnd
💡 Result:
In the io.github.Rosemoe.sora-editor library (version 0.23.6), the ContentChangeEvent class is part of the event system and is triggered whenever the text content in the editor changes or when setText is called [1]. While the event exists to notify listeners of content modifications [1], it is distinct from similarly named events in other libraries (such as those found in docx-editor or opentui [2][3][4]). In the context of Sora Editor, ContentChangeEvent does not inherently expose a standardized public API containing fields named source, changedText, changeStart, and changeEnd directly on the event object itself as part of its primary public interface documentation [1]. Users looking to track specific text changes typically interact with the underlying document model (often accessed via the CodeEditor component) to retrieve information about edits. If you are developing a plugin or integration requiring specific diff information (such as start/end positions or the text replaced/inserted), you may need to consult the source code for the ContentChangeEvent class within the editor module, as internal implementations may evolve between versions [5][6]. For further implementation details, you can refer to the official documentation and repository [1][7]: - Documentation: https://project-sora.github.io/sora-editor-docs/ - Repository: https://github.com/Rosemoe/sora-editor

site:github.com/Rosemoe/sora-editor "class ContentChangeEvent" "changeStart" "changedText"
💡 Result:
The terms changeStart and changedText are associated with the ContentChangeEvent class within the sora-editor project, which is a multifunctional code editor library for Android [1][2]. In the context of this library, ContentChangeEvent is an event used to track modifications made to the document's text [1][3]. The class typically includes properties that describe the nature of the change: - changeStart: Represents the starting index or position where the content change begins. - changedText: Represents the new text content that has been inserted or has replaced the previous content at the specified location. These fields are essential for maintaining synchronization between the editor's internal text buffer and external components, such as Language Server Protocol (LSP) clients, which require precise information about text edits to perform operations like syntax highlighting, diagnostics, and incremental updates [4][5]. As of August 2026, the sora-editor project has undergone significant architectural changes, including the introduction of a CodeEditorDelegate to support both traditional Android View-based editors and Jetpack Compose [6]. Developers working with this library should refer to the official documentation site (https://project-sora.github.io/sora-editor-docs/) for the most current API specifications and migration guides [2].

Capture the document snapshot before launching the coroutine. dispatchDocumentChangeEvent reads text.toString() after launch, while the range and changed text come from the callback event. A later edit can therefore produce a DocumentChangeEvent with metadata from one revision and newText from another. Capture an immutable payload, including full text and version, in the callback.

Bind the document snapshot before asynchronous refresh.
When KtSymbolIndex captures doc.version before refreshToCurrent() reads FileManager.getDocumentContents(path), update() can publish a newer snapshot in between. The resulting VersionedKtFile can contain newer content stamped with the older version.
Expose an immutable snapshot and pass the same snapshot to the refresh path.

Stack 1 of 5 for ADFA-5231. This layer is self-contained and touches no LSP code - it can be reviewed and merged on its own merits.
Removes the trigger for the ADFA-5231 redeclaration errors.
IDEEditorlaunchesdispatchDocumentChangeEventintoeditorScope(Dispatchers.Default), so both the++fileVersionand thetext.toString()snapshot happen off the UI thread. The extract-method code action emits twoTextEdits applied back-to-back in one frame, so two coroutines could stamp duplicate or decreasing versions and then write version-then-content intoFileManagerunsynchronised - leaving a reader able to pair a new version with old content. A version that moves backwards makes the Kotlin index mint a secondKtFilefor text that never changed.ActiveDocumentnow publishesversion,contentandmodifiedfrom a single immutable snapshot behind one volatile reference, so the three are never observed apart.updaterejects a strictly-older version.IDEEditorserialises change dispatches behind aMutexand makesfileVersionanAtomicInteger.FileManager.onDocumentContentChangeis the only mutation site for those fields in the repo, andActiveDocumenthas no subclasses - both verified by grep, which is what makes the snapshot rewrite safe.Known limitation, documented not fixed (
IDEEditor.kt:148-155): thefileVersionresets in the release path anddispatchDocumentOpenEventsit outside the mutex, so an editor-reuse reset can still race an in-flight increment. Taking the mutex there would mean makingdispatchDocumentOpenEventsuspend, which turnssetFile()'s synchronous contract asynchronous and reorders the open event against everything its callers do next - a real regression risk traded for a pre-existing, bounded, self-healing race.Testing
ActiveDocumentVersionTest- the backwards-version case fails without the guard. Cross-module compile of:subprojects:projects,:editorand:lsp:kotlinconfirms no other reader broke.
