OpenCode nuked my storage (318 GB added)

[pythonlearner1025]

Description

I asked claude to investigate and here's the report:

Summary

Opencode's snapshot system has consumed 318GB of disk space by:

1. Tracking the entire home directory as a git worktree
2. Leaving orphaned temp pack files with no garbage collection

Storage Breakdown

Type	Size	Files	Description
Orphaned temp packs	284 GB	6	Failed/interrupted pack operations, never cleaned
Loose git objects	34 GB	590,600	Actual snapshot data
Total	318 GB	—	For a CLI tool with no storage settings

Orphaned Files

File	Size	Date
tmp_pack_qM0CSW	108 GB	Dec 31
tmp_pack_Latw37	61 GB	Dec 31
tmp_pack_Tt4SKV	54 GB	Dec 31
tmp_pack_nuK5V1	27 GB	Dec 31
tmp_pack_vSc9OC	25 GB	Jan 9
tmp_pack_hJO3AO	7.8 GB	Jan 1

$ git count-objects -vH
size-garbage: 283.84 GiB

Issues

- No cleanup mechanism — no git gc, no pruning, no temp file cleanup
- No storage limits — grows unbounded
- No user visibility — no warnings, no settings, no documentation
- Tracks entire home directory — not just project folders

Workaround

rm -rf ~/.local/share/opencode/snapshot/

Expected

- Track project directories only, not $HOME
- Clean up temp files on startup
- Run periodic garbage collection
- Implement storage limits
- Warn users or expose settings

This issue might be a duplicate of existing issues. Please check:

• #8749: [BUG] tmp_pack Files Consuming 180GB on Ubuntu 24.04 LTS - Same orphaned temp_pack files in ~/.local/share/opencode/snapshot
• #5617: [BUG] Ubuntu 22.04 Temp_Pack Files Using All of the Storage - 79GB of tmp_pack files, related to #6845
• #6845: HUGE snapshot folder - 169GB of orphaned temp pack files affecting Linux systems
• #8577: Snapshot feature needs safeguards for large directories - Describes how snapshot runs git add on entire worktree without size checks
• #8887: [BUG] Snapshot module ignores 'watcher.ignore' config - Shows snapshot tracks all files regardless of ignore settings
• #3182: Very slow session due to 98GB of git snapshots - Same accumulation issue, user had to disable snapshots

All these issues describe the same root cause: orphaned temp_pack files and lack of garbage collection/storage limits in the snapshot system.

Feel free to ignore if your specific case differs from these.
