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>

Refactor path & config system (#25330) # The problem There were many "path tricks": * By default, Gitea uses its program directory as its work path * Gitea tries to use the "work path" to guess its "custom path" and "custom conf (app.ini)" * Users might want to use other directories as work path * The non-default work path should be passed to Gitea by GITEA_WORK_DIR or "--work-path" * But some Gitea processes are started without these values * The "serv" process started by OpenSSH server * The CLI sub-commands started by site admin * The paths are guessed by SetCustomPathAndConf again and again * The default values of "work path / custom path / custom conf" can be changed when compiling # The solution * Use `InitWorkPathAndCommonConfig` to handle these path tricks, and use test code to cover its behaviors. * When Gitea's web server runs, write the WORK_PATH to "app.ini", this value must be the most correct one, because if this value is not right, users would find that the web UI doesn't work and then they should be able to fix it. * Then all other sub-commands can use the WORK_PATH in app.ini to initialize their paths. * By the way, when Gitea starts for git protocol, it shouldn't output any log, otherwise the git protocol gets broken and client blocks forever. The "work path" priority is: WORK_PATH in app.ini > cmd arg --work-path > env var GITEA_WORK_DIR > builtin default The "app.ini" searching order is: cmd arg --config > cmd arg "work path / custom path" > env var "work path / custom path" > builtin default ## ⚠️ BREAKING If your instance's "work path / custom path / custom conf" doesn't meet the requirements (eg: work path must be absolute), Gitea will report a fatal error and exit. You need to set these values according to the error log. ---- Close #24818 Close #24222 Close #21606 Close #21498 Close #25107 Close #24981 Maybe close #24503 Replace #23301 Replace #22754 And maybe more
