The cwire-only nim-ffi (7362bfd, the re-pointed v0.2.0-rc.1 tag) crashed with a foreign-thread GC null-avltree fault inside sds_unwrap_received_message: that line branched off before the foreign-host-concurrency fix and was missing the cycle-collector rooting (GC_ref(myLib[])), so the SDS manager ref could be collected mid-use and fault on a later alloc. a66c53a is nim-ffi release/v0.2 = cwire + the full fix cherry-picked (a6b22fc event-listener GC setup + c3d135f context-recycling / GC_ref rooting). Pinned by immutable SHA (lock + deps.nix + sds.nimble) to avoid the mutable-tag drift that caused this. Validated: libsds builds, nimble test green (106/0), and the previously crashing status-go TestAcceptCRRemoveAndRepeat passes 5/5. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
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.
