refactor: drop asyncSpawn, add asyncSetup/asyncTeardown
Three asyncSpawn usages removed:

- sds.nim startPeriodicTasks: stored the periodic-task futures on
  ReliabilityManager (new field `periodicTasks: seq[FutureBase]`) so
  cleanup can cancel them on shutdown instead of leaking the loops
  against a cleared manager.
- library/sds_thread/sds_thread.nim: fireSync moved BEFORE processing,
  then `await SdsThreadRequest.process(...)` instead of asyncSpawn'ing
  it. Aligns the worker with the SP-channel + lock assumption that
  there are no concurrent requests; caller throughput is unchanged
  because the caller only waits for receipt (fireSync), not processing.
- tests TestBus repair callback: replaced asyncSpawn(deliverExcept...)
  with an explicit pending-delivery queue drained by `bus.drain()`.
  Integration tests no longer rely on `sleepAsync(10ms)` to let
  spawned deliveries finish — they await drain instead.

Tests also pick up an asyncSetup/asyncTeardown pair (tests/async_unittest.nim)
so suite fixtures can `await` directly. All `waitFor` in setup/teardown
blocks is gone; only the top-level asyncTest wrapper still uses waitFor
(once, to drive the async proc to completion).

nim-sds

Nim implementation of the e2e reliability protocol.

Prerequisites

  • Nix package manager

Quick start

git clone https://github.com/logos-messaging/nim-sds.git
cd nim-sds

# Build the shared library
nix build '.#libsds'

# Run tests
nix develop --command nimble test

Building

Desktop

nix build --print-out-paths '.#libsds'

Android

nix build --print-out-paths '.#libsds-android-arm64'
nix build --print-out-paths '.#libsds-android-amd64'
nix build --print-out-paths '.#libsds-android-x86'
nix build --print-out-paths '.#libsds-android-arm'

iOS

nix build --print-out-paths '.#libsds-ios'
Development shell

Enter the dev shell:

nix develop

Build using nimble tasks:

# Dynamic library (auto-detects OS)
nimble libsdsDynamicMac    # macOS
nimble libsdsDynamicLinux  # Linux
nimble libsdsDynamicWindows # Windows

# Static library
nimble libsdsStaticMac     # macOS
nimble libsdsStaticLinux   # Linux
nimble libsdsStaticWindows # Windows

Run tests:

nimble test

The built library is output to build/.

Android (without Nix)

Download the latest Android NDK:

cd ~
wget https://dl.google.com/android/repository/android-ndk-r27c-linux.zip
unzip android-ndk-r27c-linux.zip

Add to ~/.bashrc:

export ANDROID_NDK_ROOT=$HOME/android-ndk-r27c
export PATH=$ANDROID_NDK_ROOT/toolchains/llvm/prebuilt/linux-x86_64/bin:$PATH

Then build:

ARCH=arm64 nimble libsdsAndroid
Architecture Command
arm64 ARCH=arm64 nimble libsdsAndroid
amd64 ARCH=amd64 nimble libsdsAndroid
x86 ARCH=x86 nimble libsdsAndroid

The library is output to build/libsds.so.

Dependency management

Dependencies are managed by Nimble and pinned via nimble.lock.

To set up dependencies locally:

nimble setup -l

To update dependencies:

nimble lock

After updating nimble.lock, the Nix outputHash in nix/deps.nix must be recalculated by running nix build and updating the hash from the error output.
