* Import github.com/git-lfs/lfs-test-server as lfs module base Imported commit is 3968aac269a77b73924649b9412ae03f7ccd3198 Removed: Dockerfile CONTRIBUTING.md mgmt* script/ vendor/ kvlogger.go .dockerignore .gitignore README.md * Remove config, add JWT support from github.com/mgit-at/lfs-test-server Imported commit f0cdcc5a01599c5a955dc1bbf683bb4acecdba83 * Add LFS settings * Add LFS meta object model * Add LFS routes and initialization * Import github.com/dgrijalva/jwt-go into vendor/ * Adapt LFS module: handlers, routing, meta store * Move LFS routes to /user/repo/info/lfs/* * Add request header checks to LFS BatchHandler / PostHandler * Implement LFS basic authentication * Rework JWT secret generation / load * Implement LFS SSH token authentication with JWT Specification: https://github.com/github/git-lfs/tree/master/docs/api * Integrate LFS settings into install process * Remove LFS objects when repository is deleted Only removes objects from content store when deleted repo is the only referencing repository * Make LFS module stateless Fixes bug where LFS would not work after installation without restarting Gitea * Change 500 'Internal Server Error' to 400 'Bad Request' * Change sql query to xorm call * Remove unneeded type from LFS module * Change internal imports to code.gitea.io/gitea/ * Add Gitea authors copyright * Change basic auth realm to "gitea-lfs" * Add unique indexes to LFS model * Use xorm count function in LFS check on repository delete * Return io.ReadCloser from content store and close after usage * Add LFS info to runWeb() * Export LFS content store base path * LFS file download from UI * Work around git-lfs client issue with unauthenticated requests Returning a dummy Authorization header for unauthenticated requests lets git-lfs client skip asking for auth credentials See: https://github.com/github/git-lfs/issues/1088 * Fix unauthenticated UI downloads from public repositories * Authentication check order, Finish LFS file view logic * Ignore LFS hooks if installed for current OS user Fixes Gitea UI actions for repositories tracking LFS files. Checks for minimum needed git version by parsing the semantic version string. * Hide LFS metafile diff from commit view, marking as binary * Show LFS notice if file in commit view is tracked * Add notbefore/nbf JWT claim * Correct lint suggestions - comments for structs and functions - Add comments to LFS model - Function comment for GetRandomBytesAsBase64 - LFS server function comments and lint variable suggestion * Move secret generation code out of conditional Ensures no LFS code may run with an empty secret * Do not hand out JWT tokens if LFS server support is disabled
