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.

Add ssh certificate support (#12281) * Add ssh certificate support * Add ssh certificate support to builtin ssh * Write trusted-user-ca-keys.pem based on configuration * Update app.example.ini * Update templates/user/settings/keys_principal.tmpl Co-authored-by: silverwind <me@silverwind.io> * Remove unused locale string * Update options/locale/locale_en-US.ini Co-authored-by: silverwind <me@silverwind.io> * Update options/locale/locale_en-US.ini Co-authored-by: silverwind <me@silverwind.io> * Update models/ssh_key.go Co-authored-by: silverwind <me@silverwind.io> * Add missing creation of SSH.Rootpath * Update cheatsheet, example and locale strings * Update models/ssh_key.go Co-authored-by: zeripath <art27@cantab.net> * Update models/ssh_key.go Co-authored-by: zeripath <art27@cantab.net> * Update models/ssh_key.go Co-authored-by: zeripath <art27@cantab.net> * Update models/ssh_key.go Co-authored-by: zeripath <art27@cantab.net> * Update models/ssh_key.go * Optimizations based on feedback * Validate CA keys for external sshd * Add filename option and change default filename Add a SSH_TRUSTED_USER_CA_KEYS_FILENAME option which default is RUN_USER/.ssh/gitea-trusted-user-ca-keys.pem Do not write a file when SSH_TRUSTED_USER_CA_KEYS is empty. Add some more documentation. * Remove unneeded principalkey functions * Add blank line * Apply suggestions from code review Co-authored-by: zeripath <art27@cantab.net> * Add SSH_AUTHORIZED_PRINCIPALS_ALLOW option This adds a SSH_AUTHORIZED_PRINCIPALS_ALLOW which is default email,username this means that users only can add the principals that match their email or username. To allow anything the admin need to set the option anything. This allows for a safe default in gitea which protects against malicious users using other user's prinicipals. (before that user could set it). This commit also has some small other fixes from the last code review. * Rewrite principal keys file on user deletion * Use correct rewrite method * Set correct AuthorizedPrincipalsBackup default setting * Rewrite principalsfile when adding principals * Add update authorized_principals option to admin dashboard * Handle non-primary emails Signed-off-by: Andrew Thornton <art27@cantab.net> * Add the command actually to the dashboard template * Update models/ssh_key.go Co-authored-by: silverwind <me@silverwind.io> * By default do not show principal options unless there are CA keys set or they are explicitly set Signed-off-by: Andrew Thornton <art27@cantab.net> * allow settings when enabled * Fix typos in TrustedUserCAKeys path * Allow every CASignatureAlgorithms algorithm As this depends on the content of TrustedUserCAKeys we should allow all signature algorithms as admins can choose the specific algorithm on their signing CA * Update models/ssh_key.go Co-authored-by: Lauris BH <lauris@nix.lv> * Fix linting issue Co-authored-by: silverwind <me@silverwind.io> Co-authored-by: zeripath <art27@cantab.net> Co-authored-by: Lauris BH <lauris@nix.lv> Co-authored-by: techknowlogick <matti@mdranta.net> Co-authored-by: techknowlogick <techknowlogick@gitea.io>
