Function Details

GSIHTTPDownloadFile(download_url, destination, size, checksum, progressCB=None)

Download a file with GSI HTTP.

Define a local connection class so we can poke about at the tcp attributes here.

GSIHTTPUploadFiles(upload_url, file_list, progressCB)

Upload the given list of files to the server using HTTP.

progressCB is a callback that will be invoked this way:

   progressCB(filename, bytes_sent, total_bytes, file_done, transfer_done)

filename is the file to which the progress update applies
bytes_sent and total_bytes denote the file's progress
file_done is set when the given file upload is complete
transfer_done is set when the entire transfer is complete

If progressCB returns true, the transfer is to be cancelled.

HTTPFamilyDownloadFile(download_url, destination, size, checksum, identity=None, progressCB=None, connectionClass=<class httplib.HTTPConnection at 0x00A05F90>)

Download the given url, as user identified by identity, and place the new file in destination.

We assume the caller has determined that overwriting destination is valid, so we do not check for its existence.

progressCB is a callable that will be invoked with two arguments: the number of bytes transferred so far, and a flag that is passed as 1 if the transfer is completed. If the call to progressCB returns true, the user has cancelled the transfer.

HTTPUploadFiles(identity, upload_url, file_list, progressCB)

Upload the given list of files to the server using HTTP.

Identity is the DN of the client submitting the files.

progressCB is a callback that will be invoked this way:

   progressCB(filename, bytes_sent, total_bytes, file_done, transfer_done)

filename is the file to which the progress update applies
bytes_sent and total_bytes denote the file's progress
file_done is set when the given file upload is complete
transfer_done is set when the entire transfer is complete

If progressCB returns true, the transfer is to be cancelled.
