From 8da9c463692c67acdd69442057504450837580e0 Mon Sep 17 00:00:00 2001 From: baxyz Date: Sun, 6 Sep 2026 15:07:47 +0000 Subject: [PATCH 1/3] =?UTF-8?q?refactor(dotfiles-sync):=20=E2=99=BB?= =?UTF-8?q?=EF=B8=8F=20make=20SSH=20key=20file=20sync=20opt-in,=20drop=20r?= =?UTF-8?q?edundant=20path-fixing?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Two changes, same underlying cause: helpers4-common's new git-config-self-heal.sh (postAttachCommand) now fixes host-specific .gitconfig paths for every consumer automatically, regardless of whether dotfiles-sync is even in use — this feature no longer needs to solve that problem itself, and syncing the actual key file this feature's own signingkey rewrite existed to support is no longer the only way to get a working signing key either. - SSH private/public key file copying is now gated behind a new syncSshKeys option, default false. ~/.ssh/config and known_hosts still sync unconditionally — agent forwarding doesn't provide either of those — but actual key files no longer land on the container's filesystem unless explicitly requested. Normal SSH auth (git clone/push over SSH, ssh to a remote host) already works through the client's own forwarded ssh-agent with no local key file needed at all; copying them by default put private key material on the container's disk for no benefit in the common case, directly against what setups relying purely on agent forwarding deliberately avoid. - Removed this feature's own .gitconfig path-rewriting and verification (path-keys.sh, REHOMEABLE_PATH_KEYS/ VERIFY_ONLY_PATH_KEYS) — helpers4-common's self-heal actively fixes the same class of problem (and more: it also handles credential.helper/gpg.program pointing at a moved binary, which this feature's own version only ever warned about, never fixed), for every consumer, not just this feature's own users. Keeping both would mean two copies of the same "is this host path still valid" logic to maintain. - Now depends on helpers4-common (shares its h4_detect_cloud_env instead of an inline duplicate of the same Codespaces/Gitpod/ DevPod/WSL detection). Verified end-to-end in real Docker containers: default config skips key files while still merging config/known_hosts; enabling syncSshKeys places the key files, and helpers4-common's self-heal correctly finds the locally-synced .pub by basename to repair a still-host-shaped signingkey path. Version bumped to 1.1.0.

A leading `!` (credential.helper's shell-invocation prefix) and a leading `~/` (resolved against `TARGET_HOME`) are handled; the full value is checked first so a path containing spaces (e.g. a Windows path surfaced via WSL) isn't falsely flagged, then each whitespace-separated token that looks like a path is checked individually, so a script invoked through an always-present interpreter (`!/usr/bin/python3 /host/only/helper.py`) isn't hidden behind the interpreter. A `WARN` is printed for anything missing — sync never fails, but you get a visible signal instead of a commit silently failing to sign weeks later. On cloud environments, a missing path under `TARGET_HOME/.gnupg` gets a WARN that names the real cause (`.gnupg` sync is deliberately skipped there) instead of a generic "host-specific path?". +The host's `.gitconfig` can reference files or binaries by absolute host path (`user.signingkey` +for SSH-based commit signing; `credential.helper`, `gpg.program` shelling out to a host-specific +tool location).

Docs only, no behavior change. - **v1.0.7**: Documented the required `initializeCommand` in "Usage" (pre-creates every bind-mount source, mandatory and opt-in) so a container can't fail to start on a machine missing one of these files — a Feature's own `initializeCommand` is silently ignored by the devcontainers CLI, so this has to live in the consumer's `devcontainer.json`, not the feature. No behavior change to `sync-files.sh`. - **v1.0.4**: Removed bind-mounts for files that are frequently absent on host machines and have little value inside a devcontainer: `~/.gitignore_global` (redundant with `~/.config/git/` directory mount), `~/.config/pnpm/rc` (pnpm store-dir is counter-productive in a container), `~/.config/gh/config.yml` and `~/.config/gh/hosts.yml` (gh CLI auth managed separately), `~/.cargo/config.toml` (cargo not relevant in most containers), `~/.config/pip/pip.conf` (too environment-specific). Docker file bind-mounts fail hard if the source path doesn't exist on the host, which was causing containers to fail to start.
