* LfsProtocolServlet: Pass request and path to getLargeFileRepositoryDavid Pursehouse2016-07-271-12/+29
| | | | | | | | | | | | Passing the request and path to the method will allow implementations to have more control over determination of the backend, for example: - return different backends for different requests - accept or refuse requests based on request characteristics - etc Change-Id: I1ec6ec54c91a5f0601b620ed18846eb4a3f46783 Signed-off-by: David Pursehouse <david.pursehouse@gmail.com>

* Make the FileLfsRepository thread safeSaša Živkov2016-03-222-25/+12
| | | | | | | | | | | | | | The FileLfsRepository.out member could have been accessed from multiple threads which would corrupt the content. Don't store the AtomicObjectOutputStream in the FileLfsRepository.out but move it to the ObjectUploadListener which is instantiated per-request. Add a parallel upload test.

* Support Amazon S3 based storage for LFSMatthias Sohn2016-02-177-1/+808
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a storage implementation storing large objects in Amazon S3. The AmazonS3Repository pre-signs download and upload requests. AWS access and secret key are expected to be in the $HOME/.aws/credentials file in the following format: [default] accessKey = ... secretKey = ... Use AWS version 4 request signing [1] because it is more secure and supported by all regions. The version 3 signing is not supported in newer regions. In follow up changes we should: - implement getVerifyAction() and do actual verification. Subclasses of S3Repository can implement caching for object meta data (size) in order to avoid extra roundtrips to S3. Verification should ensure that meta data store and content of S3 storage are in sync - HEAD request used in S3Repository.getSize() seems to always return Content-length 0 in contrast to the documentation [2]. So getSize() does detect if the object exists in S3 or not but in case the object exists it always returns size 0 [1] http://docs.aws.amazon.com/general/latest/gr/signature-version-4.html [2] https://forums.aws.amazon.com/thread.jspa?threadID=223616 Change-Id: Ic47f094928a259e5264c92b3aacf6d90210907a8 Signed-off-by: Matthias Sohn <matthias.sohn@sap.com> Signed-off-by: Sasa Zivkov <sasa.zivkov@sap.com>
* Support LFS protocol and a file system based LFS storageMatthias Sohn2016-02-0430-0/+2395
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.
