Support LFS protocol and a file system based LFS storage
Implement LfsProtocolServlet handling the "Git LFS v1 Batch API" protocol [1]. Add a simple file system based LFS content store and the debug-lfs-store command to simplify testing. Introduce a LargeFileRepository interface to enable additional storage implementation while reusing the same protocol implementation. At the client side we have to configure the lfs.url, specify that we use the batch API and we don't use authentication: [lfs] url = http://host:port/lfs batch = true [lfs "http://host:port/lfs"] access = none the git-lfs client appends the "objects/batch" to the lfs.url. Hard code an Authorization header in the FileLfsRepository.getAction because then git-lfs client will skip asking for credentials. It will just forward the Authorization header from the response to the download/upload request. The FileLfsServlet supports file content storage for "Large File Storage" (LFS) server as defined by the Github LFS API [2]. - upload and download of large files is probably network bound hence use an asynchronous servlet for good scalability - simple object storage in file system with 2 level fan-out - use LockFile to protect writing large objects against multiple concurrent uploads of the same object - to prevent corrupt uploads the uploaded file is rejected if its hash doesn't match id given in URL The debug-lfs-store command is used to run the LfsProtocolServlet and, optionally, the FileLfsServlet which makes it easier to setup a local test server.
