molluskandClaude Fable 5 5b80a1a010 core: pull the ticket off presence before the reap wait on host fault
Gemini's merge-round review (P2, CERTAIN): the fault handler ran
`stop_host().await` first, and a host that merely closed stdout but
lives on — trapped SIGINT, wedged — makes that call burn the full 2 s
stop grace before the SIGKILL fallback. For that whole window the dead
share stayed advertised: peers could still click Watch on it, and the
sharer's own UI kept saying "sharing".

The handler now retires the share where the fault is decided, not where
the corpse is confirmed: presence ticket removal and ScreenShareStopped
are emitted before the reap wait, and only the explanatory error (which
carries the unconfirmed-reap caveat) waits for `stop_host`. The
Stopped-before-Error contract is unchanged and still gated.

StopScreenShare's identical reap-then-presence ordering predates S2 and
is deliberately left alone (user-initiated stop, lower stakes); recorded
as a follow-up note instead of churning reviewed main-line code.

PeerSpeak icon PeerSpeak

Decentralized, peer-to-peer voice chat — full-mesh, NAT-traversing, with no central server. Built in Rust on iroh (QUIC), PipeWire audio, the Opus codec, and an iced GUI.

Create a room, share the join ticket, and talk. Everyone connects directly to everyone else; relays are only used to punch through NATs when a direct path isn't available.

Features

Rooms & sessions

  • Create a room → shareable join ticket; join by pasting a ticket.
  • Full-mesh multi-peer rooms with live presence.
  • Recent-rooms list to hop back into a room someone's still in.
  • Remembered nickname and in-call duration timer.

Audio

  • PipeWire capture/playback, selectable input and output devices, per-app gain.
  • Opus codec (48 kHz mono, 20 ms frames) with an adaptive jitter buffer + packet-loss concealment.
  • Noise gate with a draggable threshold on a live mic meter (test your mic off-call too).
  • Mix-bus soft limiter and opt-in echo cancellation (PipeWire WebRTC AEC + noise suppression).

Voice controls

  • Self-mute, deafen, and rebindable push-to-talk.
  • Per-peer volume, local mute, and speaking indicators.

Text chat

  • In-room text chat over the gossip plane, with clickable links and inline image/audio attachments.
  • Drag-selectable, copyable messages; right-click context menu on all text fields.

Shared music listening

  • Build a personal playlist of local audio files with a full transport (play/pause, seek, reorder).
  • Let others tune in: peers stream your current track, timeline-synced and gapless, sitting under voice at their own volume.

Screen share (via pixelpass)

  • Share your screen; peers click 👁 Watch to open the stream in mpv (vlc fallback).
  • Live badges on sharing peers; per-app audio capture.

Recording & notifications

  • Local call recording (mic + incoming mix → WAV in ~/peerspeak-recordings/).
  • Desktop notifications and event chimes with per-event custom sound overrides.

UI & networking

  • Selectable room layouts (3-Column, Bottom Dock, Drawer) with draggable, persisted dividers.
  • 10 built-in themes (Catppuccin, Dracula, Nord, Tokyo Night, Gruvbox, Solarized…), all WCAG-AA checked.
  • Network mode picker (relay-no-discovery default, full n0, or direct-only); retained-address reconnect.
  • Config, window size/position, and all preferences persisted to ~/.config/peerspeak/.

See docs/FEATURES.md for the full inventory and field-test status, and docs/ARCHITECTURE.md for internals.

Roadmap

  • Contacts & invites — friends list with invite-notification one-click join (design in docs/contacts-plan.md).
  • Spatial audio & per-peer EQ.
  • Soundboard — play short clips into the call mix.
  • Room persistence / invite links beyond the raw ticket.
  • Windows support — cross-compiles and launches under Wine today; needs a real WASAPI audio pass (see docs/WINDOWS.md).

Building

PeerSpeak builds with a stable Rust toolchain (edition 2024). Install the system dependencies below, then:

cargo build --release
./target/release/peerspeak

System dependencies

Arch Linux

sudo pacman -S --needed rust pipewire opus pkgconf git

Debian / Ubuntu

sudo apt install build-essential pkg-config clang libclang-dev \
  libpipewire-0.3-dev libopus-dev libasound2-dev libxcb1-dev

Plus a Rust toolchain via rustup. clang/libclang are needed for the PipeWire bindings (bindgen).

At runtime you need a running PipeWire server. Screen sharing additionally requires pixelpass on your PATH, and mpv (or vlc) to watch a peer's share.

Packaging

  • Arch: cd packaging && makepkg -si (uses packaging/PKGBUILD).
  • Debian/Ubuntu: .deb is built with cargo-deb from the [package.metadata.deb] block in Cargo.toml. Build inside a Debian/Ubuntu environment so the binary links that distro's glibc.
  • Windows: see docs/WINDOWS.md.
