This PR fixes a small issue with chained (layered) config.toml file merging. The old logic didn't properly handle profiles. In particular, if a lower-layer config overrides a profile defined in a higher-layer config, the override did not take effect. This prevents users from having project-specific profile overrides and contradicts the (soon-to-be) documented behavior of config merging. The change adds a unit test for this case. It also exposes a function from the config crate that is needed by the app server code paths to implement support for layered configs.
codex-core
This crate implements the business logic for Codex. It is designed to be used by the various Codex UIs written in Rust.
Dependencies
Note that codex-core makes some assumptions about certain helper utilities being available in the environment. Currently, this support matrix is:
macOS
Expects /usr/bin/sandbox-exec to be present.
When using the workspace-write sandbox policy, the Seatbelt profile allows
writes under the configured writable roots while keeping .git (directory or
pointer file), the resolved gitdir: target, and .codex read-only.
Linux
Expects the binary containing codex-core to run the equivalent of codex sandbox linux (legacy alias: codex debug landlock) when arg0 is codex-linux-sandbox. See the codex-arg0 crate for details.
All Platforms
Expects the binary containing codex-core to simulate the virtual apply_patch CLI when arg1 is --codex-run-as-apply-patch. See the codex-arg0 crate for details.
