Michael Bolin 9acfe8965d Extract shared HTTP transport into codex-http-client (#31323)
## Why

Codex-owned HTTP construction currently lives in `codex-client`
alongside higher-level retry, SSE, and request-telemetry policy. That
makes it difficult to apply shared network behavior consistently across
crates, particularly system proxy/PAC resolution, custom CA handling,
and the ChatGPT Cloudflare cookie policy. It also leaves no clear crate
boundary for migrating direct `reqwest` usage behind a single Codex
abstraction.

This change establishes that low-level ownership boundary without
changing request behavior. It builds on the system proxy support
introduced in #26706, #26707, #26708, and #26709.

## What changed

- Added `codex-rs/http-client` as the `codex-http-client` crate.
- Moved request/response types, the concrete `reqwest` transport, custom
CA handling, Cloudflare cookie policy, and macOS/Windows proxy
resolution into the new crate.
- Kept retry, SSE, and request-telemetry policy in `codex-client`.
- Re-exported the moved API from `codex-client`, including compatibility
aliases for `CodexHttpClient` and `CodexRequestBuilder`, so existing
consumers do not change in this PR.
- Moved the existing proxy and custom-CA tests with their
implementation.

## Scope boundary

This PR deliberately stops at the crate extraction. Stacked follow-up
#31331 migrates downstream imports from `codex-client` to
`codex-http-client`, keeping this change focused on ownership and
compatibility rather than mixing in repository-wide call-site churn.

## Review guide

GitHub reports 30 changed files, of which 17 are detected renames. A
useful review order is:

1. Review the new boundary in `codex-rs/http-client/Cargo.toml` and
`codex-rs/http-client/src/lib.rs`.
2. Review `codex-rs/codex-client/Cargo.toml` and
`codex-rs/codex-client/src/lib.rs` for what remains in the higher-level
crate and how compatibility is preserved.
3. Treat the renamed implementation and test files as moves. Their
meaningful edits are limited to crate paths and normalizing the new
crate's type names to `HttpClient` and `RequestBuilder`.
4. Review `codex-rs/Cargo.toml`, `codex-rs/Cargo.lock`, and the two
`BUILD.bazel` files as mechanical workspace integration.

## Test plan

- `just test -p codex-http-client -p codex-client` (38 tests)
- Compile-checked the unchanged `codex-api`, `codex-backend-client`,
`codex-cloud-tasks`, `codex-exec-server`, `codex-login`, and
`codex-model-provider` consumers against the compatibility re-exports.

Codex CLI is a coding agent from OpenAI that runs locally on your computer.

Codex CLI splash


If you want Codex in your code editor (VS Code, Cursor, Windsurf), install in your IDE.
If you want the desktop app experience, run codex app or visit the Codex App page.
If you are looking for the cloud-based agent from OpenAI, Codex Web, go to chatgpt.com/codex.


Quickstart

Installing and running Codex CLI

Run the following on Mac or Linux to install Codex CLI:

curl -fsSL https://chatgpt.com/codex/install.sh | sh

Run the following on Windows to install Codex CLI:

powershell -ExecutionPolicy ByPass -c "irm https://chatgpt.com/codex/install.ps1 | iex"

Codex CLI can also be installed via the following package managers:

# Install using npm
npm install -g @openai/codex
# Install using Homebrew
brew install --cask codex

Then simply run codex to get started.

You can also go to the latest GitHub Release and download the appropriate binary for your platform.

Each GitHub Release contains many executables, but in practice, you likely want one of these:

  • macOS
    • Apple Silicon/arm64: codex-aarch64-apple-darwin.tar.gz
    • x86_64 (older Mac hardware): codex-x86_64-apple-darwin.tar.gz
  • Linux
    • x86_64: codex-x86_64-unknown-linux-musl.tar.gz
    • arm64: codex-aarch64-unknown-linux-musl.tar.gz

Each archive contains a single entry with the platform baked into the name (e.g., codex-x86_64-unknown-linux-musl), so you likely want to rename it to codex after extracting it.

Using Codex with your ChatGPT plan

Run codex and select Sign in with ChatGPT. We recommend signing into your ChatGPT account to use Codex as part of your Plus, Pro, Business, Edu, or Enterprise plan. Learn more about what's included in your ChatGPT plan.

You can also use Codex with an API key, but this requires additional setup.
