* Implemented LFS client. * Implemented scanning for pointer files. * Implemented downloading of lfs files. * Moved model-dependent code into services. * Removed models dependency. Added TryReadPointerFromBuffer. * Migrated code from service to module. * Centralised storage creation. * Removed dependency from models. * Moved ContentStore into modules. * Share structs between server and client. * Moved method to services. * Implemented lfs download on clone. * Implemented LFS sync on clone and mirror update. * Added form fields. * Updated templates. * Fixed condition. * Use alternate endpoint. * Added missing methods. * Fixed typo and make linter happy. * Detached pointer parser from gogit dependency. * Fixed TestGetLFSRange test. * Added context to support cancellation. * Use ReadFull to probably read more data. * Removed duplicated code from models. * Moved scan implementation into pointer_scanner_nogogit. * Changed method name. * Added comments. * Added more/specific log/error messages. * Embedded lfs.Pointer into models.LFSMetaObject. * Moved code from models to module. * Moved code from models to module. * Moved code from models to module. * Reduced pointer usage. * Embedded type. * Use promoted fields. * Fixed unexpected eof. * Added unit tests. * Implemented migration of local file paths. * Show an error on invalid LFS endpoints. * Hide settings if not used. * Added LFS info to mirror struct. * Fixed comment. * Check LFS endpoint. * Manage LFS settings from mirror page. * Fixed selector. * Adjusted selector. * Added more tests. * Added local filesystem migration test. * Fixed typo. * Reset settings. * Added special windows path handling. * Added unit test for HTTPClient. * Added unit test for BasicTransferAdapter. * Moved into util package. * Test if LFS endpoint is allowed. * Added support for git:// * Just use a static placeholder as the displayed url may be invalid. * Reverted to original code. * Added "Advanced Settings". * Updated wording. * Added discovery info link. * Implemented suggestion. * Fixed missing format parameter. * Added Pointer.IsValid(). * Always remove model on error. * Added suggestions. * Use channel instead of array. * Update routers/repo/migrate.go * fmt Signed-off-by: Andrew Thornton <art27@cantab.net> Co-authored-by: zeripath <art27@cantab.net>
