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.

Refactor: Move login out of models (#16199) `models` does far too much. In particular it handles all `UserSignin`. It shouldn't be responsible for calling LDAP, SMTP or PAM for signing in. Therefore we should move this code out of `models`. This code has to depend on `models` - therefore it belongs in `services`. There is a package in `services` called `auth` and clearly this functionality belongs in there. Plan: - [x] Change `auth.Auth` to `auth.Method` - as they represent methods of authentication. - [x] Move `models.UserSignIn` into `auth` - [x] Move `models.ExternalUserLogin` - [x] Move most of the `LoginVia*` methods to `auth` or subpackages - [x] Move Resynchronize functionality to `auth` - Involved some restructuring of `models/ssh_key.go` to reduce the size of this massive file and simplify its files. - [x] Move the rest of the LDAP functionality in to the ldap subpackage - [x] Re-factor the login sources to express an interfaces `auth.Source`? - I've done this through some smaller interfaces Authenticator and Synchronizable - which would allow us to extend things in future - [x] Now LDAP is out of models - need to think about modules/auth/ldap and I think all of that functionality might just be moveable - [x] Similarly a lot Oauth2 functionality need not be in models too and should be moved to services/auth/source/oauth2 - [x] modules/auth/oauth2/oauth2.go uses xorm... This is naughty - probably need to move this into models. - [x] models/oauth2.go - mostly should be in modules/auth/oauth2 or services/auth/source/oauth2 - [x] More simplifications of login_source.go may need to be done - Allow wiring in of notify registration - *this can now easily be done - but I think we should do it in another PR* - see #16178 - More refactors...? - OpenID should probably become an auth Method but I think that can be left for another PR - Methods should also probably be cleaned up - again another PR I think. - SSPI still needs more refactors.* Rename auth.Auth auth.Method * Restructure ssh_key.go - move functions from models/user.go that relate to ssh_key to ssh_key - split ssh_key.go to try create clearer function domains for allow for future refactors here.

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.

Refactor: Move login out of models (#16199) `models` does far too much. In particular it handles all `UserSignin`. It shouldn't be responsible for calling LDAP, SMTP or PAM for signing in. Therefore we should move this code out of `models`. This code has to depend on `models` - therefore it belongs in `services`. There is a package in `services` called `auth` and clearly this functionality belongs in there. Plan: - [x] Change `auth.Auth` to `auth.Method` - as they represent methods of authentication. - [x] Move `models.UserSignIn` into `auth` - [x] Move `models.ExternalUserLogin` - [x] Move most of the `LoginVia*` methods to `auth` or subpackages - [x] Move Resynchronize functionality to `auth` - Involved some restructuring of `models/ssh_key.go` to reduce the size of this massive file and simplify its files. - [x] Move the rest of the LDAP functionality in to the ldap subpackage - [x] Re-factor the login sources to express an interfaces `auth.Source`? - I've done this through some smaller interfaces Authenticator and Synchronizable - which would allow us to extend things in future - [x] Now LDAP is out of models - need to think about modules/auth/ldap and I think all of that functionality might just be moveable - [x] Similarly a lot Oauth2 functionality need not be in models too and should be moved to services/auth/source/oauth2 - [x] modules/auth/oauth2/oauth2.go uses xorm... This is naughty - probably need to move this into models. - [x] models/oauth2.go - mostly should be in modules/auth/oauth2 or services/auth/source/oauth2 - [x] More simplifications of login_source.go may need to be done - Allow wiring in of notify registration - *this can now easily be done - but I think we should do it in another PR* - see #16178 - More refactors...? - OpenID should probably become an auth Method but I think that can be left for another PR - Methods should also probably be cleaned up - again another PR I think. - SSPI still needs more refactors.* Rename auth.Auth auth.Method * Restructure ssh_key.go - move functions from models/user.go that relate to ssh_key to ssh_key - split ssh_key.go to try create clearer function domains for allow for future refactors here.
