feat: add a setting to turn off Git integration by willsmanley · Pull Request #23876 · pingdotgg/t3code

willsmanley · 2026-10-22T21:56:13Z

Problem

T3 Code runs Git in every project folder. It saves a checkpoint after each turn and keeps checking status, diffs, branches and pull requests. People who manage Git themselves can't turn this off. On one large folder, the checkpoints filled our disk.

Change

Adds a server setting, sourceControlEnabled, under Settings → Source Control → Git integration. It's on by default.

When it's off, T3 Code treats every folder like a folder without Git, so the existing no-repo behavior applies: no checkpoints, status checks, diffs, or branch and pull request controls. The few places that call Git directly also check the setting: repo identity, auto-pull at startup, branch pull request lookup, ignored-file marks in the file tree, and worktree cleanup. The change applies without a restart.

Scope and approval

There was no prior discussion. This is a configuration option for an existing capability: it only decides whether T3 Code reads project repositories. It's on by default, so nothing changes unless someone turns it off.

Verification

I ran a built server against a scratch Git repo with one Codex turn that writes a file, and traced every process:
- Off: T3 Code started 0 Git processes and wrote no refs/t3 refs.
- On: T3 Code started 60 Git processes and wrote 2 checkpoint refs, as before.
- Codex still ran its own Git commands in both runs. The setting only covers T3 Code.
New tests check that nothing runs Git while the setting is off. They cover the VCS registry, checkpoint store, repo identity, workspace entries, startup auto-pull, branch pull request lookup and storage cleanup. vp run check:changed passes.
Screenshots are from the web app on a dev build:

🤖 Generated with Claude Code

People who manage Git themselves can now stop T3 Code from reading their repositories. With sourceControlEnabled off, the server treats every folder as having no repository: no checkpoint refs after turns, no Git status, diffs, branch or pull request lookups, and no automatic pull or worktree cleanup. The switch is under Settings > Source Control on web and mobile and applies right away. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Approvability

Verdict: Needs Human Approval

Macroscope's review found this PR requires human approval — This PR adds a server-wide Git integration switch whose disabled state changes checkpointing, repository detection, status/diff processing, auto-pull, branch/PR controls, and worktree cleanup across projects. The cross-cutting runtime behavior and new defaulted product setting warrant human review.

Walkthrough

The change adds a server-wide Git integration setting, enabled by default. When disabled, server operations skip Git-dependent work, workspace listings omit Git ignore data, and the web interface hides version control details.

Changes: Git integration setting

Layer / File(s)	Summary
Setting contract and controls `packages/contracts/src/settings.ts`, `apps/server/src/serverSettings.ts`, `apps/mobile/src/features/settings/SettingsServerControlsRouteScreen.tsx`, `apps/web/src/components/settings/ProjectDefaultsSettings.tsx`, `apps/web/src/components/settings/settingsSearch.ts`, `apps/web/src/components/chat/ThreadDetailsPanel.tsx`, `docs/user/source-control.md`	The settings contract adds `sourceControlEnabled`, defaulting to enabled. Mobile and web settings provide a Git integration control. The chat panel hides version control details when the setting is disabled. The documentation describes the setting’s effects.
Git detection and repository identity `apps/server/src/vcs/VcsDriverRegistry.ts`, `apps/server/src/project/RepositoryIdentityResolver.ts`, `apps/server/src/server.ts`, `apps/server/src/vcs/VcsDriverRegistry.test.ts`, `apps/server/src/project/RepositoryIdentityResolver.test.ts`, `apps/server/src/orchestration-v2/testkit/ProviderReplayHarness.ts`, `apps/server/scripts/evaluate-thread-titles.ts`	Git detection and repository identity resolution return no repository when source control is disabled. Server layers and test setups provide server settings to these components.
Git-dependent server operations `apps/server/src/checkpointing/*`, `apps/server/src/git/GitManager.ts`, `apps/server/src/git/GitManager.test.ts`, `apps/server/src/serverRuntimeStartup.ts`, `apps/server/src/serverRuntimeStartup.test.ts`, `apps/server/src/storageCleanup.ts`, `apps/server/src/storageCleanup.test.ts`	Checkpoint operations, pull request lookup, automatic project pulls, and worktree cleanup skip Git-dependent work when source control is disabled. Tests cover these cases.
Workspace listings without Git `apps/server/src/workspace/WorkspaceEntries.ts`, `apps/server/src/workspace/WorkspaceEntries.test.ts`, `apps/server/src/workspace/WorkspaceFileSystem.test.ts`, `apps/server/src/server.ts`	Workspace listings omit Git ignore classification, and ignored-file queries return no files when source control is disabled. Server wiring and tests provide and verify this behavior.

Merge Risk: Moderate · up to f0bfb

Git integration can be disabled while cleanup is in progress, yet the cleanup may still remove a worktree. Coordinate these operations before merging.

Recheck Git integration before removing a worktree.

If a user turns Git integration off during a cleanup sweep, this initial check has already passed. The later settings comparison checks cleanup rules but not sourceControlEnabled. The sweep can therefore reach removeLinkedWorktree after the setting turns off. Recheck the current setting before cleanup runs Git or removes the worktree.

Cleanup checked the setting once at the start of a sweep. Turning Git integration off while a sweep was measuring a worktree did not stop it, and the worktree was still removed. The checks that run again before removal now include the setting, so the sweep keeps the worktree. Co-Authored-By: Claude Opus 5.5 <[email protected]>

Coordinate setting changes with destructive cleanup.

If sourceControlEnabled changes after the final check, the conditional cleanupGit call and the subsequent submoduleRemoval and removeLinkedWorktree calls can still run. The settings semaphore does not cover this cleanup sequence, and these cleanup APIs do not cancel when the setting changes.
