Network.GitLFS
Description
This implementation of the git-lfs API uses http Request and Response, but leaves actually connecting up the http client to the user.
You'll want to use a Manager that supports https, since the protocol uses http basic auth.
Some LFS servers, notably Github's, may require a User-Agent header in some of the requests, in order to allow eg, uploads. No such header is added by default, so be sure to add your own.

data ParsedTransferResponse op #
parseTransferResponse :: IsTransferResponseOperation op => ByteString -> ParsedTransferResponse op #
Parse the body of a response to a transfer request.
Making transfers
downloadOperationRequest :: DownloadOperation -> Maybe Request #
Builds a http request to perform a download.
uploadOperationRequests :: UploadOperation -> (ServerSupportsChunks -> RequestBody) -> SHA256 -> Integer -> Maybe [Request] #
Builds http request to perform an upload. The content to upload is provided, along with its SHA256 and size.
When the LFS server requested verification, there will be a second Request that does that; it should be run only after the upload has succeeded.
When the LFS server already contains the object, an empty list may be returned.
newtype ServerSupportsChunks #
When the LFS server indicates that it supports Transfer-Encoding chunked, this will contain a true value, and the RequestBody provided to uploadOperationRequests may be created using RequestBodyStreamChunked. Otherwise, that should be avoided as the server may not support the chunked encoding.
Constructors
| ServerSupportsChunks Bool |
Endpoint discovery
The endpoint of a git-lfs server.
guessEndpoint :: URI -> Maybe Endpoint #
Guesses the LFS endpoint from the http url of a git remote.
https://github.com/git-lfs/git-lfs/blob/master/docs/api/server-discovery.md
modifyEndpointRequest :: Endpoint -> (Request -> Request) -> Endpoint #
When an Endpoint is used to generate a Request, this allows adjusting that Request.
This can be used to add http basic authentication to an Endpoint:
modifyEndpointRequest (guessEndpoint u) (applyBasicAuth "user" "pass")
sshDiscoverEndpointCommand :: FilePath -> TransferRequestOperation -> [String] #
Command to run via ssh with to discover an endpoint. The FilePath is the location of the git repository on the ssh server.
Note that, when sshing to the server, you should take care that the hostname you pass to ssh is really a hostname and not something that ssh will parse an an option, such as -oProxyCommand=".
parseSshDiscoverEndpointResponse :: ByteString -> Maybe Endpoint #
Parse the json output when doing ssh endpoint discovery.
Errors
data TransferResponseError #
This is an error with a TransferRequest as a whole. It's also possible for a TransferRequest to overall succeed, but fail for some objects; such failures use TransferResponseObjectError.
