|
* Previously, the formatted output of 'ceph pg stat -f ...' was a full
|
|
pg dump that included all metadata about all PGs in the system. It
|
|
is now a concise summary of high-level PG stats, just like the
|
|
unformatted 'ceph pg stat' command.
|
|
|
|
|
|
|
|
|
|
* All JSON dumps of floating point values were incorrecting surrounding the
|
|
value with quotes. These quotes have been removed. Any consumer of structured
|
|
JSON output that was consuming the floating point values was previously having
|
|
to interpret the quoted string and will most likely need to be fixed to take
|
|
the unquoted number.
|
|
|
|
* The 'category' field for objects has been removed. This was originally added
|
|
to track PG stat summations over different categories of objects for use by
|
|
radosgw. It is no longer has any known users and is prone to abuse because it
|
|
can lead to a pg_stat_t structure that is unbounded. The librados API calls
|
|
that accept this field now ignore it, and the OSD no longers tracks the
|
|
per-category summations.
|
|
|
|
* The output for 'rados df' has changed. The 'category' level has been
|
|
eliminated, so there is now a single stat object per pool. The structure of
|
|
the JSON output is different, and the plaintext output has one less column.
|
|
|
|
* The 'rados create <objectname> [category]' optional category argument is no
|
|
longer supported or recognized.
|
|
|
|
* rados.py's Rados class no longer has a __del__ method; it was causing
|
|
problems on interpreter shutdown and use of threads. If your code has
|
|
Rados objects with limited lifetimes and you're concerned about locked
|
|
resources, call Rados.shutdown() explicitly.
|
|
|
|
* There is a new version of the librados watch/notify API with vastly
|
|
improved semantics. Any applications using this interface are
|
|
encouraged to migrate to the new API. The old API calls are marked
|
|
as deprecated and will eventually be removed.
|
|
|
|
* The librados rados_unwatch() call used to be safe to call on an
|
|
invalid handle. The new version has undefined behavior when passed
|
|
a bogus value (for example, when rados_watch() returns an error and
|
|
handle is not defined).
|
|
|
|
* The structure of the formatted 'pg stat' command is changed for the
|
|
portion that counts states by name to avoid using the '+' character
|
|
(which appears in state names) as part of the XML token (it is not
|
|
legal).
