ssync currently does the wrong thing when replicating object dirs
containing both a .data and a .meta file. The ssync sender uses a
single PUT to send both object content and metadata to the receiver,
using the metadata (.meta file) timestamp. This results in the object
content timestamp being advanced to the metadata timestamp,
potentially overwriting newer object data on the receiver and causing
an inconsistency with the container server record for the object.
For example, replicating an object dir with {t0.data(etag=x), t2.meta}
to a receiver with t1.data(etag=y) will result in the creation of
t2.data(etag=x) on the receiver. However, the container server will
continue to list the object as t1(etag=y).
This patch modifies ssync to replicate the content of .data and .meta
separately using a PUT request for the data (no change) and a POST
request for the metadata. In effect, ssync replication replicates the
client operations that generated the .data and .meta files so that
the result of replication is the same as if the original client requests
had persisted on all object servers.
Apart from maintaining correct timestamps across sync'd nodes, this has
the added benefit of not needing to PUT objects when only the metadata
has changed and a POST will suffice.
Taking the same example, ssync sender will no longer PUT t0.data but will
POST t2.meta resulting in the receiver having t1.data and t2.meta.
The changes are backwards compatible: an upgraded sender will only sync
data files to a legacy receiver and will not sync meta files (fixing the
erroneous behavior described above); a legacy sender will operate as
before when sync'ing to an upgraded receiver.
Changes:
- diskfile API provides methods to get the data file timestamp
as distinct from the diskfile timestamp.
- diskfile yield_hashes return tuple now passes a dict mapping data and
meta (if any) timestamps to their respective values in the timestamp
field.
- ssync_sender will encode data and meta timestamps in the
(hash_path, timestamp) tuple sent to the receiver during
missing_checks.
- ssync_receiver compares sender's data and meta timestamps to any
local diskfile and may specify that only data or meta parts are sent
during updates phase by appending a qualifier to the hash returned
in its 'wanted' list.
- ssync_sender now sends POST subrequests when a meta file
exists and its content needs to be replicated.
- ssync_sender may send *only* a POST if the receiver indicates that
is the only part required to be sync'd.
- object server will allow PUT and DELETE with earlier timestamp than
a POST
- Fixed TODO related to replicated objects with fast-POST and ssync
