Two user-reported issues.
=== GLIBC too new (reported via twitter) ===
Our linux-amd64 and linux-arm64 gnu builds were compiled on
ubuntu-latest (24.04, GLIBC 2.39), which means the resulting binaries
refuse to load on anything older:
./mhrv-rs: /lib/x86_64-linux-gnu/libc.so.6: version 'GLIBC_2.39'
not found (required by ./mhrv-rs)
Users on Ubuntu 22.04 / Mint 21 (GLIBC 2.35) — the typical user in Iran
where this project's target audience lives, and where they can't
dist-upgrade because they're behind exactly the kind of network
restriction this tool exists to bypass — could not run the gnu builds
at all.
Fix: pin the linux-gnu matrix entries to ubuntu-22.04 runners. GLIBC
2.35 is now the minimum; binaries load on Ubuntu 22.04, Mint 21,
Debian 12, Fedora 36+, RHEL 9+ and everything newer.
Users on older distros (Ubuntu 20.04, CentOS 7) can still use the
static musl builds (mhrv-rs-linux-musl-amd64.tar.gz et al.) which
have no GLIBC dependency at all.
=== Short-screen laptops — main window content clipped (PR #6) ===
Co-authored fix from @v4g4b0nd-0x76 in PR #6 (manually applied to
avoid pulling in 400 lines of unrelated cargo-fmt churn):
- Wrap the CentralPanel body in ScrollArea::vertical()
.auto_shrink([false; 2]) so everything stays reachable on short
screens.
- Lower the min_inner_size from [420, 540] to [420, 400] so laptops
with ~13" screens at default scaling can shrink the window without
clipping UI elements.
Closes#6.

The messense/rust-musl-cross images expect to run as root so cargo can
write to /root/.cargo. Overriding the container user to match the host
UID broke cargo's registry cache with 'Permission denied' before a
single file compiled. Drop the flag and chown the target/ tree after
the build instead.
A user on OpenWRT x86_64 reported the linux release doesn't run there —
root cause was glibc vs musl mismatch (our gnu binary was looking for a
dynamic linker that doesn't exist on router userlands). Add two musl
targets that produce fully static PIE binaries:
- x86_64-unknown-linux-musl -> mhrv-rs-linux-musl-amd64.tar.gz
- aarch64-unknown-linux-musl -> mhrv-rs-linux-musl-arm64.tar.gz
CI uses the messense/rust-musl-cross docker images (better-maintained
than cargo-zigbuild with a pinned zig, which has version regressions
on the ar wrapper between 0.13 and 0.16).
Locally verified:
- both archs cross-compile green in docker
- resulting x86_64 binary (3.3 MB) runs in an alpine:latest container,
--version / --help work, no dynamic lib requirements
The musl archive skips the UI (routers are headless) and swaps run.sh
for a procd init script (assets/openwrt/mhrv-rs.init) expecting the
binary at /usr/bin/mhrv-rs and config at /etc/mhrv-rs/config.json.
Side effect: switched tokio-rustls to default-features=false + ring
(was pulling aws-lc-rs transitively, which can't easily cross-compile
for musl). The main crate already uses ring explicitly, so no runtime
behavior change.
README gets a 'Running on OpenWRT (or any musl distro)' section in
both English and Persian with scp + procd enable/start recipe.
Closes#2.
First run needs the CLI to install the MITM CA into the system trust
store (sudo/admin prompt), which the UI alone can't do reliably from a
double-click. Add a small launcher for each platform that runs the CLI
with --install-cert once, then starts the UI. Each release archive now
contains a run.* script alongside the binaries.
The arm64 multiarch apt setup was failing because the Azure mirror on
GitHub runners only serves amd64. Since we don't build the UI for
aarch64-linux (server target), we only need the cross-compiler itself,
which is amd64-native. Drop the arm64 system libs and the best-effort
UI build step.
New bin 'mhrv-rs-ui' behind the 'ui' feature flag. CLI users pay
zero egui compile cost; UI users get a single static binary.
UI features:
- Config form (Apps Script ID, auth key, Google IP, front domain,
ports, log level, verify_ssl)
- Start/Stop buttons that spawn the proxy on a dedicated tokio thread
- Live stats (relay calls, failures, cache hit rate, bytes relayed,
blacklisted scripts) polled every ~700ms
- Test button (end-to-end relay probe)
- Install CA / Check CA buttons
- Recent log panel (last 200 lines)
- Dense, dark, utility-look: no emojis, no cards, no gradients
Architecture:
- Refactored crate into lib + two bins (mhrv-rs, mhrv-rs-ui).
src/lib.rs exposes all modules, main.rs uses them via 'use mhrv_rs::...'
- New src/data_dir.rs: platform-appropriate user data dir
(~/Library/Application Support/mhrv-rs on macOS,
~/.config/mhrv-rs on Linux, %APPDATA%\mhrv-rs on Windows).
CLI falls back to ./config.json for backward compat.
- CA moves to {data_dir}/ca/ca.crt (was ./ca/ca.crt).
- UI background thread owns the tokio runtime and proxy handle;
communicates with UI via std::mpsc commands + Arc<Mutex<UiState>>.
- macOS .app bundle: assets/macos/Info.plist template + build-app.sh
that assembles .app from the binary. Bundled into release zips.
- CI: Linux system libs (libxkbcommon, libwayland, libxcb*, libx11,
libgl, libgtk-3) installed on Ubuntu runners for eframe. aarch64
Linux UI is best-effort cross-compile. Windows MinGW, macOS native.
25 lib tests still pass. 5MB release UI binary on macOS.
