Ctrl+C on `upgrade` used to kill the process wherever it happened to be, potentially in the middle of a workspace command. It now stops at the next iteration boundary instead. ## Behavior - **First SIGINT/SIGTERM** — the runner finishes what it started, then stops instead of starting new work. Exits with `130` (SIGINT) or `143` (SIGTERM), following the 128+signal convention, so orchestrators can tell an interruption apart from a failure. - **Second signal** — immediate exit, leaving the command in progress unfinished. - **SIGKILL** — untrappable, same outcome as a second signal. Nothing is rolled back on stop: the run resumes from the last command recorded in `upgradeMigration`. ## Opt-in per command Registering a `SIGINT` listener removes Node's default kill-on-signal behavior, so a command that installs a handler without honoring the flag would ignore the first Ctrl+C entirely. Handlers are therefore opt-in via `CommandShutdownService.listenToShutdownSignals()`, called by the two commands that stop at a boundary: - `UpgradeCommand` - `WorkspaceCommandRunner`, the base for standalone workspace commands Everything else keeps today's behavior and dies on the first signal, `run-instance-commands` included: instance commands are transactional and cursor-guarded, so a hard kill rolls back and a rerun skips what completed. `install-application`, `rebuild-application-default-deps` and `install-pre-installed-apps` iterate over workspaces without going through `WorkspaceCommandRunner`, so they are not armed either; they are one call away if we want them. The server and worker processes share these services and never arm anything, so their shutdown semantics are unchanged. ## Where the flag is checked `CommandShutdownService` exposes a single boolean, `isShutdownRequested()`, read only by the iteration runners: - `UpgradeSequenceRunnerService.runInner` — before each sequence step - `WorkspaceIteratorService.iterate` — before each workspace There is deliberately no `AbortSignal`: in-flight work is never cancelled, it is allowed to finish. Individual commands know nothing about shutdown, so a workspace that has started runs its whole pending segment before the run stops. Each workspace ends up either fully done with the segment or untouched, never scattered at some cursor inside it. That keeps resume state coarse and the change out of the command layer, at the cost of a longer stop latency, which the second Ctrl+C covers. `WorkspaceIteratorReport` gained an `interrupted` flag. The sequence runner needs it: stopping partway through the workspace list and then advancing the cursor would run an instance step against workspaces that are not aligned yet, so it returns instead. ## Deployment note Under Kubernetes, `terminationGracePeriodSeconds` must exceed the time for one workspace to finish its segment, otherwise the SIGTERM path degrades into a SIGKILL. Documented in `docs/UPGRADE_COMMANDS.md`. ## Testing - New unit test for `CommandShutdownService` (7 cases); 293 tests pass across `database/commands` and `core-modules/upgrade` - `tsgo -p tsconfig.json` clean - oxlint and oxfmt clean on all touched files

Why Twenty
Twenty gives technical teams the building blocks for a custom CRM that meets complex business needs and quickly adapts as the business evolves. Twenty is the CRM you build, ship, and version like the rest of your stack.

Installation
Cloud
The fastest way to get started. Sign up at twenty.com and spin up a workspace in under a minute, with no infrastructure to manage and always up to date.
Build an app
Scaffold a new app with the Twenty CLI:
npx create-twenty-app my-app
Define objects, fields, and views as code:
import { defineObject, FieldType } from 'twenty-sdk/define';
export default defineObject({
nameSingular: 'deal',
namePlural: 'deals',
labelSingular: 'Deal',
labelPlural: 'Deals',
fields: [
{ name: 'name', label: 'Name', type: FieldType.TEXT },
{ name: 'amount', label: 'Amount', type: FieldType.CURRENCY },
{ name: 'closeDate', label: 'Close Date', type: FieldType.DATE_TIME },
],
});
Then ship it to your workspace:
npx twenty app:publish --private
See the app development guide for objects, views, agents, and logic functions.
Self-hosting
Run Twenty on your own infrastructure with Docker Compose, or contribute locally via the local setup guide.
Everything you need
Twenty gives you the building blocks of a modern CRM (objects, views, workflows, and agents) and lets you extend them as code. Here's a tour of what's in the box.
