## Why The package builder already fetches `rg` from a checked-in DotSlash manifest. The zsh packaging work needs the same fetch/cache/size-check/SHA-256/extract path for another manifest, but keeping that refactor inside the zsh PR makes the review harder to follow. This PR factors the existing `rg`-specific implementation into a reusable helper with no intended behavior change for `rg` packaging. ## What Changed - Added `scripts/codex_package/dotslash.py` for checked-in DotSlash manifest parsing, archive download, cache reuse, size validation, SHA-256 validation, and member extraction. - Updated `scripts/codex_package/ripgrep.py` to delegate to the shared helper. - Preserved the existing `rg` manifest path, cache key, destination filename, and executable-bit behavior. ## Testing - `python3 -m py_compile scripts/codex_package/dotslash.py scripts/codex_package/ripgrep.py scripts/codex_package/cli.py scripts/codex_package/layout.py scripts/codex_package/zsh.py` - `python3 -m unittest discover scripts/codex_package` --- [//]: # (BEGIN SAPLING FOOTER) Stack created with [Sapling](https://sapling-scm.com).

Codex package builder
This package contains the implementation behind scripts/build_codex_package.py.
The top-level script is the stable executable entry point; these modules keep the
package-building logic split by responsibility.
The builder creates a canonical Codex package directory:
.
├── codex-package.json
├── bin
│ └── <entrypoint>[.exe]
├── codex-resources
│ ├── bwrap # Linux only
│ ├── codex-command-runner.exe # Windows only
│ └── codex-windows-sandbox-setup.exe # Windows only
└── codex-path
└── rg[.exe]
The package directory is the primary artifact. Archive formats such as
.tar.gz, .tar.zst, and .zip are serializations of that directory.
If --target is omitted, the builder uses the release target for the current
host platform. On Linux, that default is a musl target to match Codex release
artifacts; pass a GNU Linux target explicitly for native glibc local builds. If
--package-dir is omitted, the builder creates a new temporary directory and
prints its path after the package is built.
The --variant flag selects the package entrypoint. Supported variants are
codex and codex-app-server. The version field in codex-package.json is
read from [workspace.package].version in codex-rs/Cargo.toml.
Source-built artifacts
Artifacts built from this repository are built by the package builder in one
grouped cargo build command per package when they are needed and no prebuilt
override was provided:
- all targets: the selected entrypoint, unless
--entrypoint-binis provided - Linux targets:
bwrap, unless--bwrap-binis provided - Windows targets:
codex-command-runnerandcodex-windows-sandbox-setup, unless the corresponding prebuilt helper flags are provided
The default cargo profile is dev-small because local iteration should favor
fast, small builds. Release jobs should pass --cargo-profile release and an
explicit target. Release jobs that already built and signed/notarized the
entrypoint should pass --entrypoint-bin so the package contains that exact
binary instead of rebuilding it.
Release jobs that already built package resource binaries should also pass the
corresponding resource flags: --bwrap-bin for Linux packages, and
--codex-command-runner-bin plus --codex-windows-sandbox-setup-bin for
Windows packages. This keeps package archive creation as a pure staging step
after signing instead of rebuilding resources.
When the builder source-builds an entrypoint for a Darwin or Linux target, it
downloads and verifies the matching Codex-built V8 release pair before invoking
Cargo and sets RUSTY_V8_ARCHIVE plus RUSTY_V8_SRC_BINDING_PATH for that
build. Windows targets keep Cargo's release-build MSVC artifact path. Explicit
overrides remain authoritative when both variables are already set. Set
V8_FROM_SOURCE=1 to leave the build with the v8 crate source-build path.
rg is not built from this repository, so the builder fetches it from the
DotSlash manifest at scripts/codex_package/rg. Downloaded archives are cached
under $TMPDIR/codex-package/<target>-rg and are reused only after the recorded
size and SHA-256 digest have been verified. Pass --rg-bin to use a local
ripgrep executable instead.
