[sourceware.org, connector.rs, proxmox.com, simple.rs] Subject: [pbs-devel] [POC proxmox proxmox-backup 0/4] use custom DNS resolver for X-BeenThere: pbs-devel@lists.proxmox.com X-Mailman-Version: 2.1.29 Precedence: list List-Id: Proxmox Backup Server development discussion List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Reply-To: Proxmox Backup Server development discussion Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7bit Errors-To: pbs-devel-bounces@lists.proxmox.com Sender: "pbs-devel" As discussed in issue #4788 [0], statically linking of the `proxmox-backup-client` still suffers from possible incompatible dependencies on the NSS module libraries, further described in [1]. This proof of concept drafts a possible workaround by relying on `hickory-dns` [2], using the hickory-resolver for name resolution instead of the default `getaddrinfo` based `GaiResolver` used by the hyper http client, as suggested by Thomas. These patches still need some polishing, but allow already to compile a static binary without the glibc issues as descibied in the issue, therefore sending them for possible more widespread testing. Initial testing on ArchLinux with glic 2.40+r16+gaa533d58ff-2, previously leading to floating point exceptions, now allows to backup without issues using the patched client. A major downside is the required dependencies for hickory-dns`, as with the feature `system-config` enabled (used to read nameservers from `/etc/resolv.conf`), also the windows dependencies on `ipconfig` and it's subdependencies are required.
