## Why `codex-core` enabled `deterministic_process_ids` through a self dev-dependency. That forced a second feature-resolved build of the same crate, which increased compile time and test latency. ## What Changed - Removed the `deterministic_process_ids` feature from `codex-rs/core/Cargo.toml`. - Removed the self dev-dependency on `codex-core` that enabled that feature. - Removed the Bazel `deterministic_process_ids` crate feature for `codex-core`. - Added a test-only `AtomicBool` override in unified exec process-id allocation. - Added a test-support setter for that override and re-exported it from `codex-core`. - Enabled deterministic process IDs in integration tests via `core_test_support` ctor. ## Behavior - Production behavior remains random process IDs. - Unit tests remain deterministic via `cfg(test)`. - Integration tests remain deterministic via explicit test-support initialization. ## Validation - `just fmt` - `cargo test -p codex-core unified_exec::` - `cargo test -p codex-core --test all unified_exec -- --test-threads=1` - `cargo tree -p codex-core -e features` (verified the removed feature path)
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.
