## Summary Fixes [go-gitea/gitea#37564](https://github.com/go-gitea/gitea/issues/37564): when an OIDC provider returns a `picture` claim, Gitea is supposed to download that image as the user's avatar (if `[oauth2_client] UPDATE_AVATAR = true`). Two latent bugs prevented this from working consistently: 1. **Default Go User-Agent rejected by some image hosts.** `oauth2UpdateAvatarIfNeed` used `http.Get`, which sends `User-Agent: Go-http-client/1.1`. Hosts like `upload.wikimedia.org` reject that UA with `403`, and every error path silently returned, so the user was left with an identicon and **no log line** to diagnose the issue. 2. **Link-account *register* path skipped avatar sync.** First-time OIDC sign-ins where auto-registration is disabled (or required a username/password retype) go through `LinkAccountPostRegister`, which created the user but never called `oauth2SignInSync`. So the avatar / full name / SSH keys from the IdP were dropped on the floor for those users, even though the existing-account-link path (`oauth2LinkAccount`) and the auto-register path (`handleOAuth2SignIn`) both already did the sync. ## Changes - `routers/web/auth/oauth.go` — `oauth2UpdateAvatarIfNeed` now uses `http.NewRequest` + `http.DefaultClient.Do`, sets `User-Agent: Gitea <version>`, and logs every failure path at `Warn` (invalid URL, fetch error, non-200, body read error, oversize body, upload error). No silent failures. - `routers/web/auth/linkaccount.go` — `LinkAccountPostRegister` now calls `oauth2SignInSync` after a successful user creation, mirroring the auto-register and link-existing-account flows. - `tests/integration/oauth_avatar_test.go` — new `TestOAuth2AvatarFromPicture` integration test with five sub-cases: - `AutoRegister_FetchesAvatarFromPictureWithGiteaUA` — happy path, asserts `use_custom_avatar=true`, an avatar hash is set, exactly one HTTP request was made, and the request carried a `Gitea ` UA. The mock server enforces the UA prefix to mirror real-world hosts that reject Go's default UA. - `AutoRegister_NonOK_DoesNotUpdateAvatar` — server returns 403; user's avatar must remain unset. - `AutoRegister_EmptyPicture_NoFetch` — empty `picture` claim must not trigger any HTTP request. - `AutoRegister_UpdateAvatarFalse_NoFetch` — `UPDATE_AVATAR=false` must not trigger any HTTP request. - `LinkAccountRegister_FetchesAvatarFromPicture` — guards the `linkaccount.go` fix; without the new `oauth2SignInSync` call this assertion fails. ## Related - Upstream issue: go-gitea/gitea#37564 -------------------------------------------- AI Editor was used in this PR --------- Signed-off-by: silverwind <me@silverwind.io> Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: Claude (Opus 4.7) <noreply@anthropic.com> Co-authored-by: wxiaoguang <wxiaoguang@gmail.com> Co-authored-by: Nicolas <bircni@icloud.com>
Gitea
Purpose
The goal of this project is to make the easiest, fastest, and most painless way of setting up a self-hosted Git service.
As Gitea is written in Go, it works across all the platforms and architectures that are supported by Go, including Linux, macOS, and Windows on x86, amd64, ARM and PowerPC architectures. This project has been forked from Gogs since November of 2016, but a lot has changed.
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.
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
From the root of the source tree, run:
TAGS="bindata" make build
The build target is split into two sub-targets:
make backendwhich requires Go Stable, the required version is defined in go.mod.make frontendwhich requires Node.js LTS or greater and pnpm.
Internet connectivity is required to download the go and npm modules. When building from the official source tarballs which include pre-built frontend files, the frontend target will not be triggered, making it possible to build without Node.js.
More info: https://docs.gitea.com/installation/install-from-source
Using
After building, a binary file named gitea will be generated in the root of the source tree by default. To run it, use:
./gitea web
Note
If you're interested in using our APIs, we have experimental support with documentation.
Contributing
Expected workflow is: Fork -> Patch -> Push -> Pull Request
Note
- YOU MUST READ THE CONTRIBUTORS GUIDE BEFORE STARTING TO WORK ON A PULL REQUEST.
- If you have found a vulnerability in the project, please write privately to security@gitea.io. Thanks!
Translating
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.
