Bug Report: flush_realtime_log raises AttributeError: _realtime_log during background execution

[alaahariri]

Summary: Calling frappe.email.doctype.email_queue.email_queue.send_now in a non-request context (e.g., via API or scheduler) results in an AttributeError from frappe.realtime.flush_realtime_log() due to an uninitialized frappe.local._realtime_log.

---

Versions:

{
  "frappe": "15.71.0",
  "erpnext": "15.65.2"
}

---

Steps to Reproduce:

1. Go to Email Queue
2. Click Send Now for a queued email with attachment (e.g., Sales Invoice)
3. Observe the error in logs or API response

---

Traceback:

Traceback (most recent call last):
  File "apps/frappe/frappe/email/doctype/email_queue/email_queue.py", line 184, in send

    _func()
  File "apps/frappe/frappe/realtime.py", line 87, in flush_realtime_log
    for args in frappe.local._realtime_log:
AttributeError: _realtime_log

---

Root Cause: frappe.local._realtime_log is only initialized during web requests. When calling code from a background process, this attribute is missing, but flush_realtime_log() assumes it always exists.

---

Proposed Fix: Add a simple guard in flush_realtime_log():

def flush_realtime_log():
    if not hasattr(frappe.local, "_realtime_log"):
        return
    for args in frappe.local._realtime_log:
        emit_via_redis(*args)
