haoshu.gu 59c565adf3 Fix duplicate custom node import when cross-referenced ... When one custom node imports another custom node (e.g., via 'import custom_nodes.other_node'), the ComfyUI custom node loader would previously load the imported node twice: 1. First time: via the explicit import statement (module name: custom_nodes.other_node) 2. Second time: via the automatic custom node scanner (module name: custom_nodes/other_node) This caused issues including: - Module initialization code being executed twice - Route handlers being registered multiple times - Potential state inconsistencies and data loss This fix adds a check before loading a custom node to detect if it's already loaded in sys.modules under either the standard import name or the path-based name. If already loaded, it reuses the existing module instead of re-executing it. Benefits: - Prevents duplicate initialization of custom nodes - Allows custom nodes to safely import other custom nodes - Improves performance by avoiding redundant module loading - Maintains backward compatibility with existing custom nodes Also includes linting fix: use lazy % formatting in logging functions.		2025-12-24 05:51:37 +08:00
