Move macaron to chi (#14293) Use [chi](https://github.com/go-chi/chi) instead of the forked [macaron](https://gitea.com/macaron/macaron). Since macaron and chi have conflicts with session share, this big PR becomes a have-to thing. According my previous idea, we can replace macaron step by step but I'm wrong. :( Below is a list of big changes on this PR. - [x] Define `context.ResponseWriter` interface with an implementation `context.Response`. - [x] Use chi instead of macaron, and also a customize `Route` to wrap chi so that the router usage is similar as before. - [x] Create different routers for `web`, `api`, `internal` and `install` so that the codes will be more clear and no magic . - [x] Use https://github.com/unrolled/render instead of macaron's internal render - [x] Use https://github.com/NYTimes/gziphandler instead of https://gitea.com/macaron/gzip - [x] Use https://gitea.com/go-chi/session which is a modified version of https://gitea.com/macaron/session and removed `nodb` support since it will not be maintained. **BREAK** - [x] Use https://gitea.com/go-chi/captcha which is a modified version of https://gitea.com/macaron/captcha - [x] Use https://gitea.com/go-chi/cache which is a modified version of https://gitea.com/macaron/cache - [x] Use https://gitea.com/go-chi/binding which is a modified version of https://gitea.com/macaron/binding - [x] Use https://github.com/go-chi/cors instead of https://gitea.com/macaron/cors - [x] Dropped https://gitea.com/macaron/i18n and make a new one in `code.gitea.io/gitea/modules/translation` - [x] Move validation form structs from `code.gitea.io/gitea/modules/auth` to `code.gitea.io/gitea/modules/forms` to avoid dependency cycle. - [x] Removed macaron log service because it's not need any more. **BREAK** - [x] All form structs have to be get by `web.GetForm(ctx)` in the route function but not as a function parameter on routes definition. - [x] Move Git HTTP protocol implementation to use routers directly. - [x] Fix the problem that chi routes don't support trailing slash but macaron did. - [x] `/api/v1/swagger` now will be redirect to `/api/swagger` but not render directly so that `APIContext` will not create a html render. Notices: - Chi router don't support request with trailing slash - Integration test `TestUserHeatmap` maybe mysql version related. It's failed on my macOS(mysql 5.7.29 installed via brew) but succeed on CI. Co-authored-by: 6543 <6543@obermui.de>

Redesign Scoped Access Tokens (#24767) ## Changes - Adds the following high level access scopes, each with `read` and `write` levels: - `activitypub` - `admin` (hidden if user is not a site admin) - `misc` - `notification` - `organization` - `package` - `issue` - `repository` - `user` - Adds new middleware function `tokenRequiresScopes()` in addition to `reqToken()` - `tokenRequiresScopes()` is used for each high-level api section - _if_ a scoped token is present, checks that the required scope is included based on the section and HTTP method - `reqToken()` is used for individual routes - checks that required authentication is present (but does not check scope levels as this will already have been handled by `tokenRequiresScopes()` - Adds migration to convert old scoped access tokens to the new set of scopes - Updates the user interface for scope selection ### User interface example <img width="903" alt="Screen Shot 2023-05-31 at 1 56 55 PM" src="https://github.com/go-gitea/gitea/assets/23248839/654766ec-2143-4f59-9037-3b51600e32f3"> <img width="917" alt="Screen Shot 2023-05-31 at 1 56 43 PM" src="https://github.com/go-gitea/gitea/assets/23248839/1ad64081-012c-4a73-b393-66b30352654c"> ## tokenRequiresScopes Design Decision - `tokenRequiresScopes()` was added to more reliably cover api routes.
