v0.48.3 argonaut update released

v0.48.3 argonaut update released

[Sage Weil]

After several months, we have an important update for the argonaut v0.48.x 
series. This release contains a critical fix that can prevent data loss or 
corruption in a power loss or kernel panic situation. There are also 
several fixes for the OSDs and for the radosgw. We recommend all v0.48.x 
users upgrade.

Notes on upgrading:

 * If you are using the undocumented ceph-disk-prepare and 
   ceph-disk-activate tools, they have several new features and some 
   additional functionality. Please review the changes in behavior 
   carefully before upgrading.
 * The .deb packages now require xfsprogs.

Notable changes since v0.48.2:

 * filestore: fix op_seq write order (fixes journal replay after power 
   loss)
 * osd: fix occasional indefinitely hung slow request
 * osd: fix encoding for pool_snap_info_t when talking to pre-v0.48 
   clients
 * osd: fix heartbeat check
 * osd: reduce log noise about rbd watch
 * log: fixes for deadlocks in the internal logging code
 * log: make log buffer size adjustable
 * init script: fix for ceph status across machines
 * radosgw: fix swift error handling
 * radosgw: fix swift authentication concurrency bug
 * radosgw: dont cache large objects
 * radosgw: fix some memory leaks
 * radosgw: fix timezone conversion on read
 * radosgw: relax date format restrictions
 * radosgw: fix multipart overwrite
 * radosgw: stop processing requests on client disconnect
 * radosgw: avoid adding port to url that already has a port
 * radosgw: fix copy to not override ETAG
 * common: make parsing of ip address lists more forgiving
 * common: fix admin socket compatibility with old protocol (for collectd 
   plugin)
 * mon: drop dup commands on paxos reset
 * mds: fix loner selection for multiclient workloads
 * mds: fix compat bit checks
 * ceph-fuse: fix segfault on startup when keyring is missing
 * ceph-authtool: fix usage
 * ceph-disk-activate: misc backports
 * ceph-disk-prepare: misc backports
 * debian: depend on xfsprogs (we use xfs by default)
 * rpm: build rpms, some related Makefile changes

As argonaut is the version shipped in Ubuntu 12.10 and for the Cloud
Archive for precise I'm going to apply for Micro Release Exception
(see [0]) for ceph so that we can push minor point release updates in
a little easier via the Ubuntu SRU process.

I need to document how the following requirements are fulfilled:

1) upstream supports micro-version updates to stable releases

This should be OK _ but more detail on how bugs are selected for the
point releases would be helpful.

2) upstream has a sufficiently high level of regression testing for
their stable releases

Details of what regression testing of stable release is done by the
ceph project would be great.

3) regression tests are always run on the update before it is released
(e.g. by being enabled in the package's build)

We don't run unit tests during package build; but we do regular smoke
testing of ceph in the Ubuntu Openstack CI lab; I'm going to extend
this so we can do regression testing of Ceph for SRU's going forwards
- - this is how we validate Openstack SRU's so should be acceptable.

Help documenting 1 & 2 would be much appreciated!

Cheers

James
