Direct Windows compose calls panic
On Windows, host_uid_gid() panics through public PodmanRuntime implementations of EnvironmentBackend, ExecutionBackend, and ArtifactBackend—including prepare_env, run via host_identity, and artifact operations via align_artifact—because the guard exists only in josh_cli::commands::run::handle_compose; public josh_compose::run is unguarded too, so callers see a panic instead of the documented josh compose is not supported on Windows error. Should we reject Windows at the backend/library boundary or make host_uid_gid() propagate a defined error instead of returning a tuple and panicking?

Commit b2dbb1d addressed this comment by adding a Windows guard at the CLI compose boundary that returns the documented error before backend calls. However, direct public library/backend calls can still reach unreachable!() and panic.

make_listener unconditionally calls set_only_v6(false), so Unix [::]:<port> listeners also accept IPv4-mapped connections and become reachable on 0.0.0.0:<port> — should we limit this workaround to Windows?

restore the platform-specific behavior of the previous Tokio bind implementation: 1)
only call `set_only_v6(false)` on Windows, leaving Unix platforms to keep their default
(often IPv6-only) socket behavior so the listener isn't unintentionally exposed on
`0.0.0.0:<port>`; 2) on Unix, call `socket.set_reuse_address(true)` before
`socket.bind(&addr.into())`, using the same Unix-specific `cfg` condition as before, so
the proxy can restart reliably without hitting `EADDRINUSE`. Ensure the listener still
binds and works correctly on both Windows and Unix after these changes.

Inherited hook marker disables proxy startup
The hook_from_env() == Some("pre-receive") check routes any process with argv[0] to pre_receive_hook(), so a normal josh-proxy --local ... --remote ... inheriting JOSH_PROXY_HOOK=pre-receive skips Args::parse() and run_proxy, reads hook-only variables, and exits with failure — should we require an identifiable shim invocation or clear/validate the marker before normal startup?

Path-form runs leave cache directories behind

josh-proxy and the josh / josh-filter CLIs do not build on Windows: unix-only code is compiled unconditionally (issue josh-project#2235). Nothing here changes unix behavior. - josh-gix-ext: add component_bytes, the portable form of the path-component conversion used to match git tree entry names. On unix an OsStr is already bytes; on Windows tree names are conventionally UTF-8, so the UTF-8 encoding is the equivalent, and a component that is not valid Unicode panics rather than silently matching something else. josh-gix-ext, josh-search and josh-core all used std::os::unix::ffi::OsStrExt::as_bytes for this. (rustc suggests std::os::windows::prelude::OsStrExt here, which is not equivalent: that trait yields UTF-16 code units, not bytes.) josh-search gains josh-gix-ext as a dependency; it was already in its build graph via josh-core and in its dev-dependencies. - josh-core: write .gitmodules with LF on every platform. gix-config writes the platform's newline, and the result becomes a blob, so the same filter applied to the same input produced different objects on Windows than elsewhere. - josh-rpc: gate the tokio_fd module behind cfg(unix). It wraps raw fds with libc for the SSH shell; josh-proxy itself only uses josh_rpc::calls, which is plain serde types. This is the first compile error (E0433). - josh-proxy: split serve_namespace cfg(unix)/cfg(not(unix)). SSH serving passes git stdio through unix sockets created by josh-ssh-shell, so non-unix builds return an "unsupported on this platform" error from that endpoint instead of failing to compile. HTTP serving is unaffected. - josh-proxy: install hooks portably. Symlink on unix (unchanged), sh shim on Windows, where symlinking needs elevated privileges. Hook mode is dispatched by argv[0], which a shim cannot fake for a native executable, so the shim names the hook in JOSH_PROXY_HOOK, read once and only on Windows. The shim runs an absolute, quoted path: git runs hooks with GIT_DIR as the working directory. The hooks directory is created with fs::create_dir_all rather than shelling out to mkdir, which is not an executable on Windows. - josh-proxy: bind the listener dual-stack, in make_listener. A bare [::] socket accepts IPv4 on Linux (bindv6only defaults off) but is v6-only on Windows: the proxy starts, logs its address and looks healthy while every client dialing 127.0.0.1 is refused. - josh-cli: refuse `josh compose` on Windows, where podman is not supported, rather than inventing a uid/gid for it. - josh-cli: build valid file:// URLs from local paths with dunce::canonicalize. std's returns an extended-length path, which git rejects inside a file:// URL — issue josh-project#2288. - Two tests are gated to unix: one identifies a ref file by inode, and one builds a ref path containing a reserved Windows device name, which Windows cannot represent at all. Adds a Windows CI job in its own workflow, leaving rust.yml untouched. It runs on x86-64 and arm64, builds the supported binaries, runs the unit tests of the crates that build there, and runs functional tests against the built binaries: tests/windows/cli.sh drives the CLI against a local repository, and tests/windows/proxy.sh drives josh-proxy through a filtered clone, a pinned-SHA fetch, a reverse-filter push and reuse of its cache across a restart, with relative and space-laden cache paths as separate cases. josh-proxy needs an http upstream, so tests/windows/serve-git.ps1 hosts git http-backend behind HttpListener; the job installs nothing that Windows does not ship. On arm64 it builds the C dependencies with clang-cl, which the runner image provides: aws-lc-sys' ARM assembly is GNU-syntax and MSVC cannot assemble it. Adds docs/src/contributing/windows.md: setup, build, and the limitations. Everything above passes on Windows x86-64 and ARM64, and on macOS and Linux.

invocation and its `tests/windows` harness so hard-coded Git server port 8177 and proxy
port 42190 cannot collide with unrelated listeners. Refactor `run.ps1`, `serve-git.ps1`,
and `proxy.sh` as needed to select and pass free ports, verify the expected child
processes remain alive, and require an identifying Git/proxy response before marking
either service ready; fail the test if binding or startup fails.
User description
Internal review PR — staging the Windows port for CodeRabbit before it goes upstream to josh-project/josh. Base is
master, fast-forwarded to upstream's tip, so the diff is exactly the one commit this would be upstream.What this does
josh doesn't build on Windows at all (josh#2235 — upstream has no Windows CI or hardware). Six changes, none altering unix behavior:
josh-rpc: gatetokio_fdbehindcfg(unix)josh_rpc::calls(serde types). First compile error (E0433).josh-proxy: splitserve_namespacecfg(unix)/not(unix)josh-proxy: portable hook installshshim elsewhere. Hook mode dispatches onargv[0], which a shim can't fake, so the shim passesJOSH_HOOKand dispatch honors both.create_dir_allinstead of shelling tomkdir(not an executable on Windows).josh-compose-podman:host_uid_gid→1000:1000on non-unixjosh-proxy: dual-stack listener[::]bind accepts IPv4 on Linux but is v6-only on Windows — the proxy logs a healthy address while refusing every127.0.0.1client. Now setsIPV6_V6ONLY=0via socket2.josh-cli: validfile://URLs on Windowscanonicalize()returns\\?\C:\..., which git rejects infile://URLs — this is josh#2288, reproduced byjosh cloneinto a relative dir.Plus
docs/src/contributing/windows.md(setup incl. the clang-cl aws-lc needs on ARM64, build, run, testing, and a troubleshooting table of every failure hit along the way).Testing
Two hermetic functional suites (rigsmith/josh-binaries) — local git-HTTP server, no network:
josh-filter,josh cloneinto a relative dir (the josh clone fails withfatal: '//\\?\Z:\path\to\dir' does not appear to be a git repositoryjosh-project/josh#2288 shape),josh changes pull,josh push --base(asserting exact parent)Status: both pass on macOS arm64 and Linux; both pass on Windows x86-64 (CI) and arm64 (manual) for the same six changes applied to
r26.07.19, where CI also runs relative / space-laden / subst-drive cache-path cases. This master port compiles clean and passes both suites on unix; re-running them on Windows against this branch is in progress.Review focus
JOSH_HOOKescape hatch adds a second way to enter hook mode. Alternative would be arg-based dispatch.1000:1000is a guess that only matters if compose ever runs on Windows (it can't today).get_headsilently falls back torefs/heads/masterwhen a remote's HEAD is unborn (filters an empty branch into an empty but "successful" clone); andjosh pushwithout--basecreates a parentless commit where the proxy path refuses outright.🤖 Generated with Claude Code
