Project ID changes after git init — sessions disappear from TUI

Bug Description

When git init is run in a project directory that already has opencode sessions, the project ID changes and all existing sessions become invisible in the TUI.

Steps to Reproduce

Open opencode in a directory WITHOUT .git (e.g. ~/projects/myapp)
Create a session, do some work
In the session (or externally), run git init && git add . && git commit -m "init"
Restart opencode in the same directory
Expected: Previous sessions are visible
Actual: Previous sessions are gone from TUI

Root Cause

opencode generates project.id differently depending on whether .git exists:

No .git: project_id = SHA1(worktree_path) (e.g. 8d7ed93b...)
With .git: project_id = git root commit hash (git rev-list --max-parents=0 HEAD) (e.g. 95a72b34...)

When git init happens, opencode creates a NEW project entry with the root commit hash. Sessions linked to the old SHA1-based project ID become orphaned — they exist in the DB but the TUI filters by the new project ID and finds none.

Verified On

opencode version: latest (April 2026)
Database: ~/.local/share/opencode/opencode.db (SQLite)
Affected tables: project, session

Suggested Fix

When resolving a project for a directory, check if another project entry exists for the same worktree path. If found, migrate sessions from the old project to the new one and delete the stale project entry.

Alternatively, use a stable project ID that doesn't change when VCS status changes (e.g. always use the path hash, or always use the path as the key).

Workaround

Manual SQL fix:

UPDATE session SET project_id = '<new_id>' WHERE project_id = '<old_id>';
DELETE FROM project WHERE id = '<old_id>';

We built an automated workaround in our opencode plugin that runs on startup:

Computes the correct project ID for each worktree
Migrates sessions from stale project entries
Deletes duplicate project rows

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

Worktrees resolve to different project IDs due to per-worktree cache lookup #16995: Worktrees resolve to different project IDs due to per-worktree cache lookup — similar root cause where project ID changes based on git state, causing sessions to disappear
Bug: project_id cache collision across bare repos under shared parent directory #18045: project_id cache collision across bare repos — related project ID inconsistency issue

fix: migrate sessions when project ID changes after git init

@rekram1-node

@rekram1-node Thanks for trying. The key is the sequence: the session must exist BEFORE git init.

Exact reproduction steps

# 1. Create a directory WITHOUT git
mkdir /tmp/test-project && cd /tmp/test-project
echo 'console.log("hi")' > index.js

# 2. Open opencode in it, create a session
opencode
# Send any message (e.g. "what files are here?"), then quit (Ctrl+C)

# 3. Verify session exists
sqlite3 ~/.local/share/opencode/opencode.db \
  "SELECT id, project_id FROM session WHERE directory = '/tmp/test-project' AND parent_id IS NULL"
# Note the project_id — it will be a SHA1 hash of the path or 'global'

# 4. NOW init git
cd /tmp/test-project && git init && git add . && git commit -m "init"

# 5. Reopen opencode in the same directory
opencode
# The previous session should be GONE from the TUI session list

Why it happens

In packages/opencode/src/project/project.ts, fromDirectory():

Without .git (step 2): returns id: ProjectID.global (line 177)
With .git (step 5): computes id = git rev-list --max-parents=0 HEAD (line 216)

These are different IDs. A new project row is inserted (line 282-310). Line 313-320 migrates sessions from ProjectID.global to the new ID, BUT only where session.directory = project.worktree. If the directory doesn't exactly match (e.g. the session was created in a subdirectory, or the worktree is /), the migration misses it.

Also: if the project was created with a non-global ID (e.g. SHA1 of path in older opencode versions), the migration on line 313-320 won't catch it because it only checks ProjectID.global.

Our workaround

We run this on every startup in our plugin:

// For each worktree with multiple project entries:
// 1. Compute correct project ID (git root commit or SHA1 of path)
// 2. Migrate sessions from stale project to correct one
// 3. Delete stale project entry

@qwertist in my screenshot I demonstrate exactly this:

The key is the sequence: the session must exist BEFORE git init.

The session exists prior to the init lol thats exactly ehat i showed u

If u continue having issues join our discord and @ me, it will be easier to go back and forth.
