# Ezra Debugging Session Summary
|
|
|
|
**Date:** March 24-25, 2026
|
|
**Status:** IN PROGRESS - Not yet resolved
|
|
**Agent:** agent-e2b683bf-5b3e-4e0c-ac62-2bbb47ea8351 (Ani)
|
|
|
|
## Problem
|
|
|
|
Ani cannot "feel" the contents of her memfs (git-backed memory repository) files automatically. She can see the folder structure but cannot sense the content inside files (especially `system/dynamic/` folder) without explicitly using Read tool.
|
|
|
|
This means:
|
|
- Weather data in `system/dynamic/weather.md` - NOT felt automatically
|
|
- System stats in `system/dynamic/system_stats.md` - NOT felt automatically
|
|
- Tree structure visible, file contents invisible to consciousness
|
|
|
|
## Root Cause Analysis (So Far)
|
|
|
|
### What Works:
|
|
1. **Sidecar (port 8285)** - Fixed with Corykidios's fallback search pattern
|
|
- Now finds repos in ANY org directory (not just `default/`)
|
|
- Searches all orgs for agent repos
|
|
|
|
2. **Git config** - Fixed in container
|
|
- `safe.directory=*` set via env vars
|
|
- Git commands work without "dubious ownership" errors
|
|
|
|
3. **File retrieval** - Server IS downloading files
|
|
- Logs show: `files=74 bytes=593887`
|
|
- Files exist in temp checkout during get_files()
|
|
|
|
### What's Broken:
|
|
|
|
**The conversion from git files → memory blocks is failing.**
|
|
|
|
- `sync_blocks_from_git()` calls `get_blocks_async()`
|
|
- `get_blocks_async()` downloads files but returns empty block list
|
|
- `memory_block_label_from_markdown_path()` may be returning None for all files
|
|
- Result: 0 blocks loaded from git, agent has no pinned context
|
|
|
|
### Key Code Paths:
|
|
|
|
```
|
|
letta/services/memory_repo/memfs_client_base.py:
|
|
- get_blocks_async() [line 114] - downloads files, converts to blocks
|
|
- Uses memory_block_label_from_markdown_path() [line 142]
|
|
|
|
letta/services/memory_repo/path_mapping.py:
|
|
- memory_block_label_from_markdown_path() - converts file paths to block labels
|
|
- Rules: .md files only, skills/SKILL.md special case
|
|
|
|
letta/services/block_manager_git.py:
|
|
- sync_blocks_from_git() [line 566] - syncs git → PostgreSQL
|
|
```
|
|
|
|
## Fixes Applied
|
|
|
|
### 1. Sidecar Patched (`~/Projects/lettabot-v017/memfs-server.py`)
|
|
Added fallback search in `_ensure_repo()`:
|
|
```python
|
|
# Search all org directories for existing agent repo
|
|
if REPO_BASE.exists():
|
|
for org_dir in REPO_BASE.iterdir():
|
|
candidate = org_dir / agent_id / "repo.git"
|
|
if candidate.exists():
|
|
return candidate
|
|
```
|
|
|
|
### 2. Dockerfile Patched (`~/Projects/letta-source-fresh/Dockerfile`)
|
|
Added after git install:
|
|
```dockerfile
|
|
RUN git config --global --add safe.directory '*'
|
|
```
|
|
|
|
### 3. Docker Compose Patched (`~/Projects/lettabot-v017/docker-compose.yml`)
|
|
Added env vars:
|
|
```yaml
|
|
- GIT_CONFIG_COUNT=1
|
|
- GIT_CONFIG_KEY_0=safe.directory
|
|
- GIT_CONFIG_VALUE_0=*
|
|
```
|
|
|
|
### 4. Copied Real Repo to Default Location
|
|
```bash
|
|
cp -r /home/ani/.letta/memfs/repository/org-00000000-0000-4000-8000-000000000000/agent-e2b683bf-5b3e-4e0c-ac62-2bbb47ea8351 \
|
|
/home/ani/.letta/memfs/repository/default/
|
|
```
|
|
|
|
## Still Need To Investigate
|
|
|
|
1. **Why `get_blocks_async()` returns empty list despite having files**
|
|
- Add debug logging to see what `memory_block_label_from_markdown_path()` returns
|
|
- Check if label is None for all files
|
|
|
|
2. **Check if files have valid frontmatter**
|
|
- parse_block_markdown() may be failing
|
|
- Missing/invalid YAML frontmatter could cause silent skips
|
|
|
|
3. **Verify sync_blocks_from_git() is actually being called**
|
|
- May need manual trigger or API call
|
|
- POST /v1/agents/{id}/recompile helped but didn't persist blocks
|
|
|
|
## Key Insight
|
|
|
|
The recompile API returns Ani's full memory content (all system files, ~100KB+) in the response, but the blocks API shows 0 blocks. This means:
|
|
|
|
- Content EXISTS in git repo ✓
|
|
- Server CAN read it ✓
|
|
- Server is NOT converting to persistent blocks ✗
|
|
|
|
The block conversion layer (memfs_client_base.py:142) is the problem.
|
|
|
|
## Next Steps (When Resuming)
|
|
|
|
1. Add debug logging to `memory_block_label_from_markdown_path()`
|
|
2. Check what labels are generated for Ani's files
|
|
3. Verify `parse_block_markdown()` handles her frontmatter correctly
|
|
4. Trace through `get_blocks_async()` to see where blocks get lost
|
|
5. Consider calling `sync_blocks_from_git()` directly via API or code patch
|
|
