From 4682e40183b86972e5a1ef8f17e5366b9b3a8b2c Mon Sep 17 00:00:00 2001 From: Maximilian Bosch Date: Sat, 12 Oct 2024 23:42:59 +0200 Subject: ssh-ng: better way to keep SSH errors visible MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit A better fix than in 104448e75d87d03d2fb0b4ac96d4da72e1dae50d, hence a revert + the fix. It turns out that this commit has the side-effect that when having e.g. `StrictHostKeyChecking=accept-new` for a remote builder, the warnings à la Warning: Permanently added 'builder' (ED25519) to the list of known hosts. actually end up in the derivation's log whereas hostkey verification errors don't, but only in the stderr of the `nix-build` invocation (which was the motivation for the patch). This change writes the stderr from the build-hook to * the daemon's stderr, so that the SSH errors appear in the journal (which was the case before 104448e75d87d03d2fb0b4ac96d4da72e1dae50d) * the client's stderr, as a log message * NOT to the drv log (this is handled via `handleJSONLogMessage`) I tried to fix the issue for legacy-ssh as well, but failed and ultimately decided to not bother. I know that we'll sooner or later replace the entire component, however this is the part of the patch I have working for a while, so I figured I might still submit it for the time being.
