1.36.19-linux Release Notes

🚨 Critical User-Reported Fixes

This release addresses three severe usability issues reported by real users:

Problem 1: Enormous Package List (30+ Minutes on Cellular)

Before: minis-dev-setup forced installation of ~800MB packages (gcc, ffmpeg, openjdk-21, golang, gradle)
After: Split into lightweight (150MB, 30s) and full (opt-in, 10-20min)

Problem 2: apt Blocks All Shell Commands

Before: apt holds lock indefinitely; all subsequent shell_execute timeout
After: 5-minute timeout with clear error; non-apt commands run concurrently

Problem 3: Cannot Kill Running Script

Before: apt_try retries 8 times; killing apt-get spawns new process
After: SIGTERM handler for clean exit; no retry loops in lightweight version

✨ What's New

Split Developer Setup

minis-dev-setup (lightweight, auto-run on boot):

• Only essentials: ca-certificates, curl, wget, python3, git, nodejs, psmisc, unzip
• ~150MB download, completes in 30-60 seconds
• 60s lock timeout (fail-fast if apt is busy)
• Non-blocking boot

minis-dev-setup-full (opt-in, manual run):

• All heavy toolchain: gcc/g++/make/cmake, ffmpeg, openjdk-21, golang, gradle
• ~800MB download, 10-20 minutes
• Run with: minis-dev-setup-full or nohup minis-dev-setup-full &
• 30-minute timeout, Ctrl+C interruptible

apt Lock Timeout

SandboxResourceGate.kt:

withTimeout(5 * 60 * 1000L) { // 5 minutes
    aptMutex.withLock { block() }
}

Shell commands no longer hang indefinitely when apt is running. Clear error after 5 minutes:

apt/dpkg is busy for 5+ minutes (likely minis-dev-setup).
Kill the apt process and retry.

SIGTERM Handler

Both scripts now handle termination gracefully:

trap 'minis_release_apt_lock; exit 143' TERM

kill <pid> releases the lock and exits cleanly (exit code 143).

Optimized seedNetworkTools

RootfsManager.kt:

• Early exit if all essentials already present
• Node.js install is best-effort, doesn't block boot
• Clearer logging

📊 Performance Impact

🔧 Files Changed

• minis-dev-setup - Rewritten (56 lines, essentials only)
• minis-dev-setup-full - New script (97 lines, full toolchain)
• SandboxResourceGate.kt - Added 5-minute timeout for apt lock
• RootfsManager.kt - Early exit in seedNetworkTools
• FIX-DEV-SETUP.md - Full technical documentation

📦 Downloads

• APK: minis-ultra-com.openminis.linux.apk
• libunwind: libunwind.a

🧪 Testing

• Lightweight seed completes in <60s on cellular
• Shell commands don't timeout during apt operations
• kill <pid> exits cleanly without orphan processes
• Full toolchain installs all packages successfully
• Lock timeout fires after 5 minutes with clear error

⚠️ Breaking Changes

None. Existing users see faster boot with smaller package set. Full toolchain is still available via minis-dev-setup-full.
