Add POST capability to ssync for .meta files
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 Related spec change-id: I60688efc3df692d3a39557114dca8c5490f7837e Co-Authored-By: Clay Gerrard <clay.gerrard@gmail.com> Closes-Bug: 1501528 Change-Id: I97552d194e5cc342b0a3f4b9800de8aa6b9cb85b
