iris: task logs should default to tail mode

[ravwojdyla-agent]

Summary

The GetTaskLogs RPC does not send tail: true from the frontend LogViewer, unlike FetchLogs (process logs) which does. This means task log queries use ORDER BY id ASC LIMIT N, returning the first N lines instead of the last N.

When a task has more than the limit (default 10k), the user sees the oldest logs and misses the most recent ones — which are typically the most useful for debugging.

Details

• Frontend: LogViewer.vue sends tail: true for FetchLogs (line 52) but omits it for GetTaskLogs (lines 41-45).
• Backend: service.py passes request.tail through to LogStore.get_logs() / get_logs_by_prefix(), which already supports tail=True (reverses the ORDER BY to DESC and takes the last N rows).

Fix

Send tail: true in the GetTaskLogs RPC params in LogViewer.vue.

Research

FetchLogs (process logs) sends tail: true but GetTaskLogs (task logs) omits it. The backend already supports tail — LogStore.get_logs() reverses ORDER BY to DESC when tail=True.

Relevant code

• LogViewer.vue#L41-L45 - GetTaskLogs params (missing tail)
• LogViewer.vue#L52 - FetchLogs sends tail: true
• log_store.py#L182-L190 - tail=True branch in get_logs()

Proposed Fix

Add tail: true to the GetTaskLogs RPC params in LogViewer.vue, matching the existing FetchLogs behavior.
