Extensions: stale progress file causes wrong status after disable/uninstall

Bug Report: Stale progress file causes wrong status after disable/uninstall

Severity: Medium
Category: Error Handling
Platform: All (macOS, Linux, Windows/WSL2)
Confidence: Confirmed (API-tested on macOS Apple Silicon)

Description

After installing an extension, the progress file persists through disable and uninstall operations. Because _compute_extension_status() checks progress files before checking actual extension state, a stale progress file overrides the real status. An uninstalled extension can show as "installing" in the UI.

Affected File(s)

• dream-server/extensions/services/dashboard-api/routers/extensions.py (lines 103-128, 898-980, 983-1027)

Root Cause

The disable_extension() and uninstall_extension() endpoints do not clean up the progress file in data/extension-progress/{service_id}.json. The stale progress file (with status: "started") persists, and _compute_extension_status() checks it first (lines 103-128). Since _is_stale() uses a 300-second window for "started" status, the stale file takes priority over the actual extension state for up to 5 minutes.

The only cleanup mechanism is _cleanup_stale_progress() which runs lazily on catalog refresh and only removes files after 15 minutes (started) or 1 hour (other states).

Evidence

# _compute_extension_status checks progress FIRST (line 103-128)
progress = _read_progress(ext_id)
if progress:
    ps = progress.get("status", "")
    if ps == "started":
        if not _is_stale(progress.get("updated_at", ""), max_age_seconds=300):
            svc = services_by_id.get(ext_id)
            if not (svc and svc.status == "healthy"):
                return "installing"  # <-- returned even after uninstall!

Platform Analysis

• macOS: Affected — confirmed via API testing
• Linux: Affected — same Python code path
• Windows/WSL2: Affected — same Python code path

Reproduction

1. Install an extension: POST /api/extensions/chromadb/install
2. Wait for status to show "enabled" or "installing"
3. Disable: POST /api/extensions/chromadb/disable
4. Check status: GET /api/extensions/chromadb → shows "installing" instead of "disabled"
5. Uninstall: DELETE /api/extensions/chromadb
6. Check status: GET /api/extensions/chromadb → shows "installing" instead of "not_installed"

Impact

• Extension status is wrong in the UI for up to 5 minutes after disable/uninstall
• Users see a spinner ("installing") for an extension they just removed
• Confusing UX — user might think the operation failed

Suggested Approach

Delete the progress file in both disable_extension() and uninstall_extension() (and purge_extension_data()) after the operation completes.

Live verification update:

• Progress files not cleaned on disable/uninstall: CONFIRMED. Neither the disable endpoint (line 881) nor uninstall endpoint (line 965) cleans up progress files from /data/extension-progress/.
• Mitigation exists: _read_progress() ignores files older than 1 hour, and _compute_extension_status() ignores stale "pulling"/"starting" progress older than 2 minutes when started_at == updated_at.
• The bug is self-healing within 1 hour but still causes incorrect status in that window.

Could not reproduce with actual stale files (no user extensions installed on test deployment), but the code path is clear.

Verification Agent Report:

Status: PARTIALLY CONFIRMED (code analysis + live deployment)

Code trace confirms:

• Disable endpoint (line 881): Does NOT clean up progress files from /data/extension-progress/
• Uninstall endpoint (line 965): Does NOT clean up progress files — only removes the extension directory via shutil.rmtree(ext_dir), not the progress file

Mitigating factors found:

• _read_progress() auto-expires files older than 1 hour (unless status is "error")
• _compute_extension_status() ignores stale "pulling"/"starting" progress older than 2 minutes when started_at == updated_at

Conclusion: The bug is real — progress files are never explicitly cleaned on disable/uninstall. The stale status window is up to 1 hour before TTL guards auto-expire the entries. Not permanent, but a poor UX for that window. Could not reproduce with actual stale files since no user extensions were installed on the test deployment.

PR Linkage Update:

This issue should be resolved as an additional commit on PR Light-Heart-Labs#825 (fix/extension-status-health-check).

PR Light-Heart-Labs#825 modifies the extension status logic in extensions.py, adding health-based status computation. The progress file cleanup on disable/uninstall fits thematically — both are about extension status accuracy. Adding cleanup of /data/extension-progress/{service_id}.json in the disable and uninstall endpoints would complete the status lifecycle that PR Light-Heart-Labs#825 is improving.

Currently, disable (line 881) and uninstall (line 965) leave stale progress files behind. A single Path(DATA_DIR / "extension-progress" / f"{service_id}.json").unlink(missing_ok=True) in each endpoint would fix it.
