Regression test for #workspace-files: workspace file tree must stay
|
||
|
|
visible across REPEATED blank-page reloads (not just the first one).
|
||
|
|
|
||
|
|
Bug shape: PR #1182's ephemeral guard removed the stored session ID from
|
||
|
|
localStorage when it detected a 0-message session. That made the FIRST
|
||
|
|
refresh work (loadSession → loadDir → files render, then guard fires and
|
||
|
|
clears the key), but the SECOND refresh fell into the "no saved session"
|
||
|
|
boot path which never calls loadDir() — file tree went blank.
|
||
|
|
|
||
|
|
Fix: keep the session ID in localStorage. Every refresh runs the same
|
||
|
|
path:
|
||
|
|
loadSession() → loadDir() populates the workspace
|
||
|
|
→ ephemeral guard fires → S.session=null in memory only
|
||
|
|
→ workspace panel stays open with files visible
|
||
|
|
|
||
|
|
The session ID persisting in localStorage is harmless — server-side
|
||
|
|
``all_sessions()`` filters Untitled+0-message sessions so no phantom
|
||
|
|
sidebar entry appears, and ``newSession()`` overwrites the key when the
|
||
|
|
user actually creates a real session.
