test: vendor zsh fork via DotSlash and stabilize zsh-fork tests (#12518)
## Why The zsh integration tests were still brittle in two ways: - they relied on `CODEX_TEST_ZSH_PATH` / environment-specific setup, so they often did not exercise the patched zsh fork that `shell-tool-mcp` ships - once the tests consistently used the vendored zsh fork, they exposed real Linux-specific zsh-fork issues in CI In particular, the Linux failures were not just test noise: - the zsh-fork launch path was dropping `ExecRequest.arg0`, so Linux `codex-linux-sandbox` arg0 dispatch did not run and zsh wrapper-mode could receive malformed arguments - the `turn_start_shell_zsh_fork_subcommand_decline_marks_parent_declined_v2` test uses the zsh exec bridge (which talks to the parent over a Unix socket), but Linux restricted sandbox seccomp denies `connect(2)`, causing timeouts on `ubuntu-24.04` x86/arm This PR makes the zsh tests consistently run against the intended vendored zsh fork and fixes/hardens the zsh-fork path so the Linux CI signal is meaningful. ## What Changed - Added a single shared test-only DotSlash file for the patched zsh fork at `codex-rs/exec-server/tests/suite/zsh` (analogous to the existing `bash` test resource). - Updated both app-server and exec-server zsh tests to use that shared DotSlash zsh (no duplicate zsh DotSlash file, no `CODEX_TEST_ZSH_PATH` dependency). - Updated the app-server zsh-fork test helper to resolve the shared DotSlash zsh and avoid silently falling back to host zsh. - Kept the app-server zsh-fork tests configured via `config.toml`, using a test wrapper path where needed to force `zsh -df` (and rewrite `-lc` to `-c`) for the subcommand-decline test. - Hardened the app-server subcommand-decline zsh-fork test for CI variability: - tolerate an extra `/responses` POST with a no-op mock response - tolerate non-target approval ordering while remaining strict on the two `/usr/bin/true` approvals and decline behavior - use `DangerFullAccess` on Linux for this one test because it validates zsh approval flow, not Linux sandbox socket restrictions - Fixed zsh-fork process launching on Linux by preserving `req.arg0` in `ZshExecBridge::execute_shell_request(...)` so `codex-linux-sandbox` arg0 dispatch continues to work. - Moved `maybe_run_zsh_exec_wrapper_mode()` under `arg0_dispatch_or_else(...)` in `app-server` and `cli` so wrapper-mode handling coexists correctly with arg0-dispatched helper modes. - Consolidated duplicated `dotslash -- fetch` resolution logic into shared test support (`core/tests/common/lib.rs`). - Updated `codex-rs/exec-server/tests/suite/accept_elicitation.rs` to use DotSlash zsh and hardened the zsh elicitation test for Bazel/zsh differences by: - resolving an absolute `git` path - running `git init --quiet .` - asserting success / `.git` creation instead of relying on banner text ## Verification - `cargo test -p codex-app-server turn_start_zsh_fork -- --nocapture` - `cargo test -p codex-exec-server accept_elicitation -- --nocapture` - `bazel test //codex-rs/exec-server:exec-server-all-test --test_output=streamed --test_arg=--nocapture --test_arg=accept_elicitation_for_prompt_rule_with_zsh` - CI (`rust-ci`) on the final cleaned commit: `Tests โ ubuntu-24.04 - x86_64-unknown-linux-gnu` and `Tests โ ubuntu-24.04-arm - aarch64-unknown-linux-gnu` passed in [run 22291424358](https://github.com/openai/codex/actions/runs/22291424358) |

feat(core): zsh exec bridge (#12052)
zsh fork PR stack: - https://github.com/openai/codex/pull/12051 - https://github.com/openai/codex/pull/12052 ๐ ### Summary This PR introduces a feature-gated native shell runtime path that routes shell execution through a patched zsh exec bridge, removing MCP-specific behavior from the shell hot path while preserving existing CommandExecution lifecycle semantics. When shell_zsh_fork is enabled, shell commands run via patched zsh with per-`execve` interception through EXEC_WRAPPER. Core receives wrapper IPC requests over a Unix socket, applies existing approval policy, and returns allow/deny before the subcommand executes. ### Whatโs included **1) New zsh exec bridge runtime in core** - Wrapper-mode entrypoint (maybe_run_zsh_exec_wrapper_mode) for EXEC_WRAPPER invocations. - Per-execution Unix-socket IPC handling for wrapper requests/responses. - Approval callback integration using existing core approval orchestration. - Streaming stdout/stderr deltas to existing command output event pipeline. - Error handling for malformed IPC, denial/abort, and execution failures. **2) Session lifecycle integration** SessionServices now owns a `ZshExecBridge`. Session startup initializes bridge state; shutdown tears it down cleanly. **3) Shell runtime routing (feature-gated)** When `shell_zsh_fork` is enabled: - Build execution env/spec as usual. - Add wrapper socket env wiring. - Execute via `zsh_exec_bridge.execute_shell_request(...)` instead of the regular shell path. - Non-zsh-fork behavior remains unchanged. **4) Config + feature wiring** - Added `Feature::ShellZshFork` (under development). - Added config support for `zsh_path` (optional absolute path to patched zsh): - `Config`, `ConfigToml`, `ConfigProfile`, overrides, and schema. - Session startup validates that `zsh_path` exists/usable when zsh-fork is enabled. - Added startup test for missing `zsh_path` failure mode. **5) Seatbelt/sandbox updates for wrapper IPC** - Extended seatbelt policy generation to optionally allow outbound connection to explicitly permitted Unix sockets. - Wired sandboxing path to pass wrapper socket path through to seatbelt policy generation. - Added/updated seatbelt tests for explicit socket allow rule and argument emission. **6) Runtime entrypoint hooks** - This allows the same binary to act as the zsh wrapper subprocess when invoked via `EXEC_WRAPPER`. **7) Tool selection behavior** - ToolsConfig now prefers ShellCommand type when shell_zsh_fork is enabled. - Added test coverage for precedence with unified-exec enabled. |
