swift.obj.ssync_sender.
Sender
(daemon, node, job, suffixes, remote_check_objs=None)¶Bases: object
Sends SSYNC requests to the object server.
These requests are eventually handled by
ssync_receiver
and full documentation about the
process is there.
connect
()¶Establishes a connection and starts an SSYNC request with the object server.
disconnect
()¶Closes down the connection to the object server once done with the SSYNC request.
missing_check
()¶Handles the sender-side of the MISSING_CHECK step of a SSYNC request.
Full documentation of this can be found at
Receiver.missing_check()
.
readline
()¶Reads a line from the SSYNC response body.
httplib has no readline and will block on read(x) until x is read, so we have to do the work ourselves. A bit of this is taken from Python’s httplib itself.
send_delete
(url_path, timestamp)¶Sends a DELETE subrequest with the given information.
send_post
(url_path, df)¶send_put
(url_path, df)¶Sends a PUT subrequest for the url_path using the source df (DiskFile) and content_length.
updates
()¶Handles the sender-side of the UPDATES step of an SSYNC request.
Full documentation of this can be found at
Receiver.updates()
.
swift.obj.ssync_sender.
decode_wanted
(parts)¶Parse missing_check line parts to determine which parts of local diskfile were wanted by the receiver.
The encoder for parts is
encode_wanted()
swift.obj.ssync_sender.
encode_missing
(object_hash, ts_data, ts_meta=None, ts_ctype=None)¶Returns a string representing the object hash, its data file timestamp
and the delta forwards to its metafile and content-type timestamps, if
non-zero, in the form:
<hash> <ts_data> [m:<hex delta to ts_meta>[,t:<hex delta to ts_ctype>]]
The decoder for this line is
decode_missing()
