* move migrating to backend * add loading image when migrating and fix tests * fix format * fix lint * add redis task queue support and improve docs * add redis vendor * fix vet * add database migrations and fix app.ini sample * add comments for task section on app.ini.sample * Update models/migrations/v84.go Co-Authored-By: lunny <xiaolunwen@gmail.com> * Update models/repo.go Co-Authored-By: lunny <xiaolunwen@gmail.com> * move migrating to backend * add loading image when migrating and fix tests * fix fmt * add redis task queue support and improve docs * fix fixtures * fix fixtures * fix duplicate function on index.js * fix tests * rename repository statuses * check if repository is being create when SSH request * fix lint * fix template * some improvements * fix template * unified migrate options * fix lint * fix loading page * refactor * When gitea restart, don't restart the running tasks because we may have servel gitea instances, that may break the migration * fix js * Update models/repo.go Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * Update docs/content/doc/advanced/config-cheat-sheet.en-us.md Co-Authored-By: guillep2k <18600385+guillep2k@users.noreply.github.com> * fix tests * rename ErrTaskIsNotExist to ErrTaskDoesNotExist * delete release after add one on tests to make it run happy * fix tests * fix tests * improve codes * fix lint * fix lint * fix migrations
