this dramatically improves time to run `cargo test -p codex-core` (~25x speedup). before: ``` cargo test -p codex-core 35.96s user 68.63s system 19% cpu 8:49.80 total ``` after: ``` cargo test -p codex-core 5.51s user 8.16s system 63% cpu 21.407 total ``` both tests measured "hot", i.e. on a 2nd run with no filesystem changes, to exclude compile times. approach inspired by [Delete Cargo Integration Tests](https://matklad.github.io/2021/02/27/delete-cargo-integration-tests.html), we move all test cases in tests/ into a single suite in order to have a single binary, as there is significant overhead for each test binary executed, and because test execution is only parallelized with a single binary.
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
macOS
Expects /usr/bin/sandbox-exec to be present.
Linux
Expects the binary containing codex-core to run the equivalent of 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.
