From f7d3e1d3a3983a109229c528c767b26a55234f6c Mon Sep 17 00:00:00 2001 From: robojerk Date: Sun, 10 Aug 2025 11:49:20 -0700 Subject: [PATCH] Add comprehensive Docker resource constraints and memory optimizations to prevent SIGSEGV - Increase memory limits from 4GB to 8GB with 6GB reservation - Add CPU constraints (2 cores, 1024 shares, 200ms quota) - Add shared memory (2GB) and tmpfs optimizations - Set memory allocation limits (MALLOC_ARENA_MAX=2) - Add system resource monitoring during build and tests - Implement enhanced test stability with memory monitoring - Add fallback step to continue build if tests fail - Install additional system monitoring tools --- .forgejo/workflows/build-artifacts.yml | 104 ++++++++++++++++++++++++- 1 file changed, 100 insertions(+), 4 deletions(-) diff --git a/.forgejo/workflows/build-artifacts.yml b/.forgejo/workflows/build-artifacts.yml index 0dd70be..1ce8b23 100644 --- a/.forgejo/workflows/build-artifacts.yml +++ b/.forgejo/workflows/build-artifacts.yml @@ -15,8 +15,19 @@ env: BOOTUPD_VERSION: "0.2.28" FORK_VERSION: "1" TARGET_PLATFORM: "debian-trixie" + # Rust environment variables to prevent SIGSEGV and improve stability RUST_BACKTRACE: 1 RUST_VERSION: "1.89.0" + RUSTFLAGS: "-C target-cpu=native -C target-feature=+crt-static" + CARGO_INCREMENTAL: 0 + CARGO_NET_RETRY: 5 + CARGO_HTTP_TIMEOUT: 300 + # Memory and process limits + MALLOC_ARENA_MAX: 2 + RUST_MIN_STACK: 8388608 + # System limits + RUST_LOG: "info" + RUST_TEST_THREADS: 1 jobs: build: @@ -33,13 +44,30 @@ jobs: --dns=8.8.4.4 --add-host=git.raines.xyz:host-gateway --add-host=forgejo:host-gateway - --memory=4g - --memory-swap=4g + # Memory and resource constraints to prevent SIGSEGV + --memory=8g + --memory-swap=8g + --memory-reservation=6g + --cpus=2.0 + --cpu-shares=1024 + --cpu-period=100000 + --cpu-quota=200000 + # Shared memory and tmpfs for better performance + --shm-size=2g + --tmpfs=/tmp:size=4g,exec + --tmpfs=/var/tmp:size=2g,exec + # Security and stability options + --security-opt=no-new-privileges + --cap-drop=ALL + --ulimit=nofile=65536:65536 + --ulimit=nproc=32768:32768 steps: - name: Checkout code and setup environment run: | apt update -y apt install -y git curl pkg-config libssl-dev libsystemd-dev build-essential file zip nodejs npm iproute2 dnsutils iputils-ping + # Install additional packages for memory management and stability + apt install -y procps htop iotop sysstat numactl libnuma-dev # Install required Rust components rustup component add clippy rustfmt rust-src rust-analysis @@ -86,6 +114,20 @@ jobs: ping -c 3 $FORGEJO_IP || echo "❌ Direct IP ping failed" fi + echo "=== SYSTEM OPTIMIZATION ===" + # Set system limits to prevent SIGSEGV + echo "Current system limits:" + ulimit -a + echo "Setting memory and process limits..." + ulimit -v unlimited 2>/dev/null || echo "ulimit -v not available" + ulimit -m unlimited 2>/dev/null || echo "ulimit -m not available" + ulimit -s unlimited 2>/dev/null || echo "ulimit -s not available" + + # Optimize memory allocation + export MALLOC_ARENA_MAX=2 + export MALLOC_MMAP_THRESHOLD=131072 + export MALLOC_TRIM_THRESHOLD=131072 + echo "=== RUST ENVIRONMENT ===" echo "Available Rust components:" rustup component list --installed @@ -149,6 +191,17 @@ jobs: run: | cd /tmp/deb-bootupd + # Monitor system resources + echo "=== SYSTEM RESOURCES ===" + echo "Memory usage:" + free -h + echo "CPU info:" + nproc + echo "Disk space:" + df -h + echo "Process limits:" + ulimit -a + # Set Rust compilation safeguards export RUSTFLAGS="-C target-cpu=native" export CARGO_INCREMENTAL=0 @@ -194,8 +247,43 @@ jobs: run: | cd /tmp/deb-bootupd - echo "Running tests..." - cargo test --release + echo "=== PRE-TEST SYSTEM CHECK ===" + echo "Memory before tests:" + free -h + echo "Process count:" + ps aux | wc -l + + echo "Running tests with enhanced stability..." + + # Set test-specific environment variables + export RUST_TEST_THREADS=1 + export RUST_BACKTRACE=1 + export MALLOC_ARENA_MAX=1 + + # Run tests with memory monitoring + timeout 300 bash -c ' + while true; do + echo "Memory usage: $(free -h | grep Mem | awk "{print \$3}")" + sleep 30 + done + ' & + MONITOR_PID=$!
