From 6b6dd13175e8620232bc41861cf0ec77c2e8fa53 Mon Sep 17 00:00:00 2001 From: Sopaco Date: Mon, 2 Mar 2026 10:29:42 +0800 Subject: [PATCH 01/14] Introduce incremental memory update system with version tracking Implements v2.5 memory architecture with: - Memory index for tracking metadata, versions, and sources - Event-driven coordination for create/update/delete operations - Cascade layer updates from file changes to ancestor directories - Vector-store synchronization ensuring consistency with filesystem - Support for 8 memory types with deduplication and merging This replaces the previous append-only approach with proper version control and cross-dimensional update propagation. --- cortex-mem-core/src/automation/indexer.rs | 6 +- cortex-mem-core/src/automation/sync.rs | 20 +- cortex-mem-core/src/cascade_layer_updater.rs | 573 +++++++++ cortex-mem-core/src/extraction/mod.rs | 2 +- cortex-mem-core/src/extraction/types.rs | 7 +- .../src/incremental_memory_updater.rs | 1072 +++++++++++++++++ cortex-mem-core/src/lib.rs | 33 + .../src/memory_event_coordinator.rs | 613 ++++++++++ cortex-mem-core/src/memory_events.rs | 289 +++++ cortex-mem-core/src/memory_index.rs | 381 ++++++ cortex-mem-core/src/memory_index_manager.rs | 395 ++++++ cortex-mem-core/src/session/extraction.rs | 14 + cortex-mem-core/src/session/manager.rs | 24 + cortex-mem-core/src/types.rs | 52 +- cortex-mem-core/src/vector_store/qdrant.rs | 4 +- cortex-mem-core/src/vector_sync_manager.rs | 496 ++++++++ cortex-mem-tools/src/operations.rs | 44 +- litho.docs/v2.5_develop_plan.md | 297 +++++ 18 files changed, 4278 insertions(+), 44 deletions(-) create mode 100644 cortex-mem-core/src/cascade_layer_updater.rs create mode 100644 cortex-mem-core/src/incremental_memory_updater.rs create mode 100644 cortex-mem-core/src/memory_event_coordinator.rs create mode 100644 cortex-mem-core/src/memory_events.rs create mode 100644 cortex-mem-core/src/memory_index.rs create mode 100644 cortex-mem-core/src/memory_index_manager.rs create mode 100644 cortex-mem-core/src/vector_sync_manager.rs create mode 100644 litho.docs/v2.5_develop_plan.md diff --git a/cortex-mem-core/src/automation/indexer.rs b/cortex-mem-core/src/automation/indexer.rs index a0ff8db..3b4d44c 100644 --- a/cortex-mem-core/src/automation/indexer.rs +++ b/cortex-mem-core/src/automation/indexer.rs @@ -96,7 +96,7 @@ impl AutoIndexer { run_id: Some(thread_id.to_string()), actor_id: None, role: Some(format!("{:?}", message.role)), - memory_type: crate::types::MemoryType::Conversational, + memory_type: crate::types::V1MemoryType::Conversational, hash: self.calculate_hash(&message.content), importance_score: 0.5, entities: vec![], @@ -189,7 +189,7 @@ impl AutoIndexer { run_id: Some(thread_id.to_string()), actor_id: None, role: Some(format!("{:?}", message.role)), - memory_type: crate::types::MemoryType::Conversational, + memory_type: crate::types::V1MemoryType::Conversational, hash: self.calculate_hash(&message.content), importance_score: 0.5, entities: vec![], @@ -592,7 +592,7 @@ impl AutoIndexer { run_id: None, actor_id: None, role: None, - memory_type: crate::types::MemoryType::Conversational, + memory_type: crate::types::V1MemoryType::Conversational, hash: self.calculate_hash(content), importance_score: 0.5, entities: vec![], diff --git a/cortex-mem-core/src/automation/sync.rs b/cortex-mem-core/src/automation/sync.rs index ad48467..86c7862 100644 --- a/cortex-mem-core/src/automation/sync.rs +++ b/cortex-mem-core/src/automation/sync.rs @@ -3,7 +3,7 @@ use crate::{ filesystem::{CortexFilesystem, FilesystemOperations}, layers::manager::LayerManager, llm::LLMClient, - types::{Memory, MemoryMetadata, MemoryType}, + types::{Memory, MemoryMetadata, V1MemoryType}, vector_store::{QdrantVectorStore, uri_to_vector_id}, ContextLayer, Result, @@ -102,7 +102,7 @@ impl SyncManager { // 同步用户记忆 (preferences, entities, events) if self.config.sync_users { let stats = self - .sync_directory("cortex://user", MemoryType::Semantic) + .sync_directory("cortex://user", V1MemoryType::Semantic) .await?; total_stats.add(&stats); } @@ -110,7 +110,7 @@ impl SyncManager { // 同步Agent记忆 (cases, skills) if self.config.sync_agents { let stats = self - .sync_directory("cortex://agent", MemoryType::Semantic) + .sync_directory("cortex://agent", V1MemoryType::Semantic) .await?; total_stats.add(&stats); } @@ -127,7 +127,7 @@ impl SyncManager { if let Ok(entries) = self.filesystem.list("cortex://resources").await { if !entries.is_empty() { let stats = self - .sync_directory("cortex://resources", MemoryType::Semantic) + .sync_directory("cortex://resources", V1MemoryType::Semantic) .await?; total_stats.add(&stats); } @@ -164,9 +164,9 @@ impl SyncManager { self.sync_directory_recursive(uri).await?

可靠性高、支持重试 | 架构复杂、依赖外部 | - -选择事件驱动的原因： -1. 记忆系统需要多个组件协同（增量更新、层级更新、向量同步） -2. 各组件处理时机不同，事件机制支持灵活调度 -3. 便于后续扩展新的事件处理器 - -### 4.2 为什么使用 `.memory_index.json`？ - -| 方案 | 优点 | 缺点 | -|------|------|------| -| **JSON 文件（已选）** | 易读、易调试、与文件系统同目录 | 并发写入需小心 | -| SQLite | 查询高效、事务支持 | 需额外依赖、与文件系统分离 | -| 内存缓存 | 性能最高 | 重启丢失、一致性难保证 | - -选择 JSON 文件的原因： -1. 与文件系统存储结构一致，便于调试 -2. 无需额外数据库依赖 -3. 内容哈希已解决大部分并发问题 - -### 4.3 层级更新策略 - -``` -文件变更触发链： -file.md 变更 - → 更新 direct_parent/.abstract.md - → 更新 direct_parent/.overview.md - → 递归向上更新 ancestor 目录 - → 到达 root 时聚合所有子目录 L0 -``` - -设计考量： -- 不立即更新，避免频繁 LLM 调用 -- 通过事件队列异步处理
