feat: hierarchical memory structure (YYYY/MM/) with automatic migration
Implement hierarchical memory structure to improve filesystem performance when dealing with large numbers of memory files. ## Changes ### Core Implementation (src/memory/internal.ts) - Add isOldMemoryFormat() - detect old flat format files - Add migrateMemoryFile() - migrate to YYYY/MM/ structure with: * Date validation (rejects invalid dates like 2025-99-99) * Atomic file creation (wx flag) to prevent race conditions * Optional logger parameter for production use - Add migrateAllMemoryFiles() - bulk migration with: * Full recursive scan via findOldFormatFiles() * Dry-run mode for preview * Detailed metrics (totalBytes, durationMs, file lists) - Update walkDir() - auto-migrate on file access - Update listMemoryFiles() - add logger parameter ### Tests (src/memory/internal.test.ts) - 20 comprehensive unit tests - Test old-format detection, date validation, race conditions - Test dry-run mode and detailed metrics - 100% coverage of key functionality ### Documentation - docs/concepts/memory-migration.md (NEW) - migration guide - docs/concepts/memory.md - backward compatibility section - docs/help/faq.md - migration FAQ entries ## Backward Compatibility - Automatic migration on file access - Old files preserved as backup - Zero breaking changes - Both formats supported

# Memory Migration Guide
|
||||
|
||||
## Overview
|
||||
|
||||
Moltbot now uses a **hierarchical memory structure** for better scalability:
|
||||
|
||||
**Before (flat):**
|
||||
```
|
||||
memory/2025-01-27.md
|
||||
memory/2025-01-26-conversation.md
|
||||
...365+ files in one directory per year
|
||||
```
|
||||
|
||||
**After (hierarchical):**
|
||||
```
|
||||
memory/2025/01/2025-01-27.md
|
||||
memory/2025/01/2025-01-26-conversation.md
|
||||
...max 31 files per directory
|
||||
```
|
||||
|
||||
## Why This Change?
|
||||
|
||||
The flat structure worked well for small memory sets, but caused issues over time:
|
||||
|
||||
- **Filesystem performance**: 1000+ files in one directory slows down filesystem operations
|
||||
- **Navigation difficulty**: Hard to find files manually
|
||||
- **No natural segmentation**: Cannot easily archive by month/year
|
||||
|
||||
The hierarchical structure solves all these issues.
|
||||
|
||||

|
||||
|
||||
## Backward Compatibility
|
||||
|
||||
**Good news:** Moltbot automatically migrates old-format files.
|
||||
|
||||
### How It Works
|
||||
|
||||
When Moltbot encounters an old-format file (`memory/YYYY-MM-DD.md`):
|
||||
|
||||
1. **Detects** the old format
|
||||
2. **Creates** the new directory structure (`memory/YYYY/MM/`)
|
||||
3. **Copies** the file to the new location
|
||||
4. **Logs** the migration
|
||||
5. **Uses** the new file going forward
|
||||
|
||||
The old file is kept as a backup (not deleted automatically).
|
||||
|
||||
### What You Need to Do
|
||||
|
||||
**Nothing.** Migration is automatic and transparent.
|
||||
|
||||
When you:
|
||||
- Search memory → old files are migrated automatically
|
||||
- Read memory → migrated files are used
|
||||
- Write memory → new format is used
|
||||
|
||||
---
|
||||
|
||||
## Migration Examples
|
||||
|
||||
### Example 1: Automatic Migration
|
||||
|
||||
You have a file at `memory/2025-01-27.md`.
|
||||
|
||||
When Moltbot reads memory:
|
||||
```
|
||||
[memory] Migrated old-format memory file: 2025-01-27.md -> memory/2025/01/2025-01-27.md
|
||||
```
|
||||
|
||||
File is now at: `memory/2025/01/2025-01-27.md`
|
||||
|
||||
### Example 2: Slug Files
|
||||
|
||||
You have `memory/2025-01-27-discussion.md`.
|
||||
|
||||
Migration creates:
|
||||
```
|
||||
memory/2025/01/2025-01-27-discussion.md
|
||||
```
|
||||
|
||||
### Example 3: Existing New-Format Files
|
||||
|
||||
If `memory/2025/01/2025-01-27.md` already exists:
|
||||
- Migration skips the old file
|
||||
- New file is kept (no overwrite)
|
||||
- Warning logged
|
||||
|
||||
---
|
||||
|
||||
## Rolling Back
|
||||
|
||||
If you need to revert to the old format:
|
||||
|
||||
1. **Stop** Moltbot
|
||||
2. **Delete** the `memory/YYYY/` directories
|
||||
3. **Restore** from backup (if you kept one)
|
||||
4. **Restart** Moltbot
|
||||
|
||||
**Note:** Old-format files are not deleted during migration, so you may have both formats present temporarily.
|
||||
|
||||
---
|
||||
|
||||
## Troubleshooting
|
||||
|
||||
### Migration Fails
|
||||
|
||||
If migration fails for a file:
|
||||
- Check file permissions
|
||||
- Ensure workspace directory is writable
|
||||
- Check logs for specific error messages
|
||||
|
||||
### Files Not Found After Migration
|
||||
|
||||
If memory files seem missing:
|
||||
- Check new location: `memory/YYYY/MM/`
|
||||
- Old files still exist in `memory/` (backup)
|
||||
- Memory search works across both formats
|
||||
|
||||
### Performance Issues After Migration
|
||||
|
||||
If you still see performance issues:
|
||||
- Run `moltbot memory status` to check index
|
||||
- Rebuild index: `moltbot memory index --force`
|
||||
- Check disk space

||||

## Timeline
|
||||
|
||||
| Version | Status |
|
||||
|---------|--------|
|
||||
| **Current** | Both formats supported, automatic migration |
|
||||
| **Future +1** | Warning: old format deprecated |
|
||||
| **Future +2** | Error: old format not supported |
|
||||
| **Future +3** | Old format removed |
|
||||
|
||||
**Recommendation:** No immediate action needed. Migration is automatic.

## FAQ
|
||||
|
||||
**Q: Will my old memory files be deleted?**
|
||||
A: No. Old files are kept as backup.
|
||||
|
||||
**Q: Do I need to update my scripts?**
|
||||
A: No. Moltbot handles both formats transparently.
|
||||
|
||||
**Q: What if I have both formats?**
|
||||
A: New format takes precedence. Old format is ignored if new exists.
|
||||
|
||||
**Q: Can I keep using the old format?**
|
||||
A: Yes, for now. Old format will be deprecated in future versions.
|
||||
|
||||
**Q: How do I know if migration happened?**
|
||||
A: Check logs for `[memory] Migrated old-format memory file` messages.

## Backward Compatibility & Migration
|
||||
|
||||
Moltbot supports **automatic migration** from the old memory format to the new hierarchical structure.
|
||||
|
||||
### Old Format vs New Format
|
||||
|
||||
**Old (flat):**
|
||||
```
|
||||
memory/2025-01-27.md
|
||||
memory/2025-01-26-conversation.md
|
||||
```
|
||||
|
||||
**New (hierarchical):**
|
||||
```
|
||||
memory/2025/01/2025-01-27.md
|
||||
memory/2025/01/2025-01-26-conversation.md
|
||||
```
|
||||
|
||||
### Automatic Migration
|
||||
|
||||
When Moltbot encounters old-format files:
|
||||
1. Detects the old format
|
||||
2. Creates `memory/YYYY/MM/` directories
|
||||
3. Copies files to new location
|
||||
4. Uses new format going forward
|
||||
|
||||
**Old files are not deleted** — they're kept as backup.
|
||||
|
||||
### What You Need to Do
|
||||
|
||||
**Nothing.** Migration is transparent and automatic.
|
||||
|
||||
Memory search, read, and write operations work seamlessly across both formats.
|
||||
|
||||

### How do I migrate my old memory files to the new format
|
||||
|
||||
Moltbot **automatically migrates** old-format memory files.
|
||||
|
||||
If you have files in the old format (`memory/YYYY-MM-DD.md`), Moltbot will:
|
||||
1. Detect them automatically
|
||||
2. Create new directories (`memory/YYYY/MM/`)
|
||||
3. Copy files to the new location
|
||||
4. Use the new format going forward

**Old files are not deleted** — they're kept as backup.

**Docs:** [Memory Migration Guide](/concepts/memory-migration)
|
||||
|
||||
### Will my old memory files still work after upgrading
|
||||
|
||||
**Yes.** Moltbot supports both old and new memory formats with automatic migration.
|
||||
|
||||
- Memory search works across both formats
|
||||
- Old files are automatically migrated when accessed
|
||||
- No manual action required
|

**Timeline:**
