rhan-oai 04a8580f33 centralize Responses retry policy (#24131)
## Why

#23951 added remote compaction v2 retries, but it left the retry and WS
-> HTTPS fallback behavior duplicated between normal Responses turns and
compaction. This follow-up centralizes the common retry handling so
future changes to fallback, retry delay, retry notifications, and retry
sleep do not have to be kept in sync across both callsites.

## What changed

- Added `core/src/responses_retry.rs` with a shared handler for
retryable Responses stream errors.
- Reused that handler from normal turn sampling and remote compaction
v2.
- Kept each callsite responsible for its retry budget: normal turns
still use `stream_max_retries`, while compaction v2 still uses
`min(stream_max_retries, 2)`.
- Preserved caller-specific behavior around non-retryable errors,
context-window errors, usage-limit errors, and compact-specific final
failure logging.

The shared handler now owns:

- WS -> HTTPS fallback warning emission
- retry delay selection, including server-requested stream retry delay
- retry logging
- first-WebSocket-retry notification suppression
- `Reconnecting... n/max` stream-error notification
- sleeping before the next retry attempt

## Verification

- `cargo test -p codex-core remote_compact_v2`
- `cargo test -p codex-core websocket_fallback`
- `just fix -p codex-core`

Did not run the full workspace test suite.

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
