Subject: [pve-devel] [PATCH 2/2] apiserver: check if file is directory before opening
Date: Wed, 15 Oct 2025 10:03:30 +0200	[thread overview]
Message-ID: <20251015080330.45927-3-n.frey@proxmox.com> (raw)
In-Reply-To: <20251015080330.45927-1-n.frey@proxmox.com>

Add a check for if the file being accessed is a directory.
This improves the error relayed to the user, which - when mistakenly
trying to access a directory instead of a file - would return:

`unable to detect content type at /usr/share/perl5/PVE/APIServer/AnyEvent.pm line 499.`
