Make Query Tool SQL file drop replace, merge, or ask. #10272 - #10763
Dropping a SQL file from the OS file manager onto the Query Tool used to insert
at the drop cursor (and on Windows/Chromium often as plain text with an empty FileList), so a second drop mixed with the previous editor content instead of
replacing it. Maintainers suggested offering insert-at-cursor as well as replace
when content already exists (#10272).
This change handles OS file drops explicitly and adds a Query Tool preference Preferences → Query Tool → Options → On SQL file drop:
Always replace content (default): clear the editor and load the file
Always merge content: insert the file at the caret (not the mouse position)
Ask: prompt with Replace / Merge / Cancel when the editor already has content;
empty editors still replace without a dialog
Also covered for Windows/Chromium:
Detect OS file drops when types includes Files even if FileList is empty
(file exposed as text/plain)
Freeze the user caret during drag so Chromium moving the contenteditable
selection under the mouse does not change the merge position
Map the insert through CodeMirror’s ChangeSet so CRLF file text does not
throw “Selection points outside of document”
Object Explorer tree drops are unchanged (still insert at drop coordinates).
OS file drop helpers live in sqlFileDrop.jsx; Editor.jsx wires the handlers.
Test plan
Open Query Tool, drop a .sql file from the OS file manager → content loads
With preference Always replace, drop a second file → editor is fully replaced
With preference Always merge, place the caret mid-query, drop a file →
content inserts at the caret (not under the mouse)
With preference Ask and non-empty editor → dialog offers Replace / Merge / Cancel
With preference Ask and empty editor → file loads with no dialog
Drop an Object Explorer object onto the editor → still inserts at the drop position
On Windows (Edge/Chrome), repeat replace/merge with CRLF .sql files
Jest: CodeMirrorCustomEditor.spec.js (OS file drop / merge / ask / tree drop cases)
Added support for dropping SQL files into the query editor. Choose whether file contents replace existing text, merge at the cursor, or prompt you when the editor already contains content.
Dropped files replace the contents of an empty editor automatically. Read-only editors remain unchanged.
When merging, file contents are inserted at the remembered cursor position. If no position is available, they are inserted at the end of the document.
You can also configure the file-drop action in query tool preferences; replacement is the default.
Handle OS file drops in the Query Tool with a preference to always
replace, always merge at the caret, or ask when content already exists.
Detect Windows/Chromium drops with empty FileList, freeze the caret
during drag, and map inserts through CodeMirror's ChangeSet for CRLF
safety.

Walkthrough
The SQL editor now handles operating-system file drops with replace, merge, or ask preferences. Merge inserts file text at a remembered caret position. The editor also updates handling for internal text drops and selection bounds.

This change adds a configurable SQL file-drop behavior (replace, merge, or ask) to the Query Tool editor. The earlier review concerns were addressed, and nothing blocking remains. Manual verification on Windows browsers is still unchecked, but that is normal pre-merge validation.

Explanation
Issue [#10272] requires a dropped SQL file to replace existing Query Tool content. The new sql_file_drop_action preference defaults to replace, and handleOsFileDrop applies replacement with setValue(). The implementation detects Windows/Chromium drops when FileList is empty and uses the text payload. The tests cover replacement, including this payload case.
Full details: Out of Scope Changes check
Explanation
The changes remain within Query Tool SQL file-drop behavior. Merge and Ask modes extend the requested replacement behavior. Caret preservation and ChangeSet mapping support merge behavior and CRLF input. The preference, dialog, drag handling, and tests support the file-drop objective. Object Explorer drops retain their existing insertion behavior. No unrelated changes are evident.

Unverified finding
Verification ran but could not confirm this finding. It is shown for review, not as a verified issue.
Do not replace SQL when the drop has no readable payload.
If types contains Files but neither files nor items provides a File, a file-only transfer supplies no plain text. getDroppedText then returns '', and the default replace action clears the existing SQL. DataTransfer.getData() does not return file contents as text. Leave the editor unchanged when neither a File nor a text payload is available. Keep empty files valid when an actual File was read.

…is dropped.
- Update `handleOsFileDrop` to return early if a file drop contains no readable text, preventing unintended changes to the SQL editor.
- Add a test case to verify that the editor remains unchanged when a file drop event has no valid text payload.
