• Since this patch is a non-breaking, non-governance upgrade, the chain version stays at v0.5.1

Patches

TempDir Cleanup Fix

• firmachaind binary creates temporary directory on each run #20
• Issue: Each firmachaind execution created a new /tmp/.firmachainXXXXXXX directory, which was never removed; causing inode growth and unnecessary disk usage, even for simple commands like firmachaind status.
• Root Cause: CosmWasm’s temporary app initialization flow did not clean up WASM temp directories after command execution.
• Solution: Added cleanup process during tempApp initialization to ensure directories are deleted properly.

Requirements

• Go: v1.21 (same as v0.5.1)

Tests

• Local: Unit Tests, CLI Commands
• Devnet: Unit Tests, CLI Commands, E2E Tests
• Testnet (Imperium-4): Unit Tests, CLI Commands, E2E Tests, Smart Contract Transactions (state-sync validation)

Detailed Description

This patch resolves the CosmWasm temp directory leakage that caused persistent /tmp/.firmachain* artifacts.

Key improvements:

• Ensures temporary WASM directories are fully cleaned after each command.
• Prevents inode exhaustion and improves node environment stability.

Who Should Upgrade

• Required:

  • Node operators experiencing growing /tmp/.firmachain* directories

• Recommended:

  • All validators and full nodes (upgrading avoids future disk bloat and improves overall reliability)
