daveaitel-openai 79cbca324a Skip history metadata scan for subagents (#12918)
Summary
- Skip `history_metadata` scanning when spawning subagents to avoid
expensive per-spawn history scans.
- Keeps behavior unchanged for normal sessions.

Testing
  - `cd codex-rs && cargo test -p codex-core` 
- Failing in this environment (pre-existing and I don't think something
I did?):
- `suite::cli_stream::responses_mode_stream_cli` (SIGKILL + OTEL export
error to http://localhost:14318/v1/logs)
- `suite::grep_files::grep_files_tool_collects_matches` (unsupported
call: grep_files)
- `suite::grep_files::grep_files_tool_reports_empty_results`
(unsupported call: grep_files)

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.

Network access and filesystem read/write roots are controlled by SandboxPolicy. Seatbelt consumes the resolved policy and enforces it.

Seatbelt also supports macOS permission-profile extensions layered on top of SandboxPolicy:

  • no extension profile provided: keeps legacy default preferences read access (user-preference-read).
  • extension profile provided with no macos_preferences grant: does not add preferences access clauses.
  • macos_preferences = "readonly": enables cfprefs read clauses and user-preference-read.
  • macos_preferences = "readwrite": includes readonly clauses plus user-preference-write and cfprefs shm write clauses.
  • macos_automation = true: enables broad Apple Events send permissions.
  • macos_automation = ["com.apple.Notes", ...]: enables Apple Events send only to listed bundle IDs.
  • macos_accessibility = true: enables com.apple.axserver mach lookup.
  • macos_calendar = true: enables com.apple.CalendarAgent mach lookup.

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.
