Giteabot f47e3d930d fix(actions): cancel tasks immediately when the runner stopped reporting (#38616) (#38644)
Backport #38616 by @bircni

Fixes jobs that get stuck in `cancelling` after Gitea is restarted while
a job is running.

Reproduction:

1. Run a job with `sleep 100`
2. Stop Gitea and wait 120s (> 100s)
3. Start Gitea — the job is still `running`; cancel it, and it stays in
`cancelling`

## Cause

A cancellation is only ever delivered to a runner as the *response* to
its `UpdateTask`
RPC. A runner that has already given up on the task — it crashed, or it
failed to report
the final state while Gitea was unreachable — never calls `UpdateTask`
again, so it never
learns about the cancellation. The task then sits in `cancelling` until
`stop_zombie_tasks`
reaps it, which needs `ZOMBIE_TASK_TIMEOUT` (10m) of silence and only
runs every 5 minutes.

Cancelling actually made this worse. xorm rewrites the `updated` column
on every `UPDATE`,
even when `Cols()` restricts the update to `status`, so persisting the
`cancelling` status
reset the zombie clock. Pressing cancel pushed the cleanup a full
`ZOMBIE_TASK_TIMEOUT`
into the future instead of bringing it forward.

## Change

`StopTask` now skips the `cancelling` handshake when the task has had no
state report from
its runner for longer than `TaskReportTimeout` (1 minute) and cancels it
directly. This
joins the two existing fallbacks — runner deleted, and runner without
cancelling support —
so every cancel path (web UI, API, concurrency, rerun) is covered.

Runners report the state of a running task every few seconds, so a
minute of silence means
the runner is gone. The value is a constant rather than a setting
because it only decides
whether the runner is still reachable, not whether a task should be
killed —
`ZOMBIE_TASK_TIMEOUT` still owns that.

### Tradeoff

If a runner is alive but has been silent for over a minute and is
cancelled in that window,
it skips the graceful post-step cleanup added in #37275. No work is
lost: the runner still
learns the outcome on its next report, because `UpdateTask` returns the
task status as the
result and the runner stops there. That is the behaviour that existed
before #37275.

Gitea

繁體中文 | 简体中文

Purpose

The goal of Gitea is to make the easiest, fastest, and most painless way of setting up a self-hosted all-in-one software development service, including Git hosting, code management, code review, issue tracking, project kanban, wiki, team collaboration, package registry and CI/CD which can reuse GitHub Actions.

As Gitea is written in Go, it works across all the platforms and architectures that are supported by Go, including Linux, macOS, FreeBSD/OpenBSD and Windows on x86, amd64, ARM, RISC-V 64 and PowerPC architectures.

For online demonstrations, you can visit demo.gitea.com.

For accessing free Gitea service (with a limited number of repositories), you can visit gitea.com.

To quickly deploy your own dedicated Gitea instance on Gitea Cloud, you can start a free trial at cloud.gitea.com, or use container (docker/podman/etc) to deploy on your own server with the official image.

Documentation

You can find comprehensive documentation on our official documentation website.

It includes installation, administration, usage, development, contributing guides, and more to help you get started and explore all features effectively.

If you have any suggestions or would like to contribute to it, you can visit the documentation repository

Building

See docs/build-setup.md for prerequisites and docs/development.md for setting up a local development environment, linting, and testing.

If you'd like to build from source or make a distribution package, see docs/build-source.md for more information.

After building, you can run ./gitea web to start the server, or ./gitea help to see all available commands.

Contributing

Expected workflow is: Fork -> Patch -> Push -> Pull Request

Note

  1. YOU MUST READ THE CONTRIBUTORS GUIDE BEFORE STARTING TO WORK ON A PULL REQUEST.
  2. New to the codebase? The development guide walks through setting up a local environment and building from source.
  3. If you have found a vulnerability in the project, please write privately to security@gitea.io. Thanks!

Translating

Crowdin

Translations are done through Crowdin. If you want to translate to a new language, ask one of the managers in the Crowdin project to add a new language there.

You can also just create an issue for adding a language or ask on Discord on the #translation channel. If you need context or find some translation issues, you can leave a comment on the string or ask on Discord. For general translation questions there is a section in the docs. Currently a bit empty, but we hope to fill it as questions pop up.

Get more information from documentation.

Official and Third-Party Projects

We provide an official go-sdk, a CLI tool called tea and an action runner for Gitea Action.

We maintain a list of Gitea-related projects at gitea/awesome-gitea, where you can discover more third-party projects, including SDKs, plugins, themes, and more.

Communication

If you have questions that are not covered by the documentation, you can get in contact with us on our Discord server or create a post in the discourse forum.
