Subject: [pve-devel] [PATCH v2 proxmox-backup 1/9] tools/BroadcastFuture: add testcase for better understanding
Date: Mon, 7 Jun 2021 17:35:24 +0200 [thread overview]
Message-ID: <20210607153532.2522267-2-s.reiter@proxmox.com> (raw)
In-Reply-To: <20210607153532.2522267-1-s.reiter@proxmox.com>
Explicitly test that data will stay available and can be retrieved
immediately via listen(), even if the future producing the data and
notifying the consumers was already run in the past.
Wasn't broken or anything, but helps with understanding IMO.
