Subject: [pve-devel] [PATCH/RFC v2 common 6/7] allow workers to count warnings and finish tasks in a WARNINGS state
Date: Fri, 9 Apr 2021 10:44:35 +0200 [thread overview]
Message-ID: <20210409084436.2454-7-f.ebner@proxmox.com> (raw)
In-Reply-To: <20210409084436.2454-1-f.ebner@proxmox.com>
as is already supported by the UI (and PBS).
A nice bonus is that warn() can be used by both workers and non-workers. For
workers, the output is redirected/duplicated as set up by {fork,tee}_worker(),
and non-erroring workers that issued a warning will end in a WARNINGS state.
Signed-off-by: Fabian Ebner <f.ebner@proxmox.com>

Changes from v1:
* use chomp in warn(), so it can also be called with newline-terminated
strings
