[runenv.pm, command.pm] Subject: [pve-devel] [PATCH installer 0/4] fix #4872: properly timeout `traceroute` command in coutry detection X-BeenThere: pve-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox VE development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 09 Feb 2024 10:57:05 -0000 For all the details, see patch #4. TL;DR: SIGALRM does not interrupt line reading using <>, causing the installer to hang on country detection. Fix it by using Proxmox::Sys::Command::run_command(), which properly interacts with SIGALRM. Patch #1 is a rather mundane fix for some niche cases, #2 and #3 are simply preparatory and to not alter existing behaviour. Christoph Heiss (4): low-level: initialize UI backend for 'dump-env' subcommand too sys: command: allow terminating the process early from log subroutine sys: command: add option to not print process output to stdout fix #4872: run env: use run_command() for country detection Proxmox/Install/RunEnv.pm | 23 ++++++++++++----------- Proxmox/Sys/Command.pm | 13 ++++++++++--- proxmox-low-level-installer | 1 + 3 files changed, 23 insertions(+), 14 deletions(-) -- 2.43.0
