* client, libcephfs: make readlink sanewip-libcephfsAndrey Kuznetsov2013-09-045-23/+24

* mds: include requested caps (namely, xattrs) on getattr replySage Weil2013-09-044-5/+16
| | | | | | | | | | | For xattrs, we only include them in the reply if we are issuing caps on them. However, in the getattr case, we need to include the snapshot of the current state. The original problem is reproduced by LibCephFS.Xattrs_ll (a simple set then get). Signed-off-by: Sage Weil <sage@inktank.com>

* client: direct read/write methods that bypass cache, cap checksAdam C. Emerson2013-09-041-0/+136
| | | | | | | | | | These methods were created to implement pNFS data server support, bypassing cap checks since the pNFS MDS holds a cap on behalf of the client, realized in the recallable layout. (Includes pieces of API v2 by Matt.) Signed-off-by: Matt Benjamin <matt@linuxbox.com>
* client: expose layout informationAdam C. Emerson2013-09-041-0/+84
| | | | | | | | | | | | | | This allows us to construct pNFS layouts and DS filehandles that match the Ceph clustering, placement, and striping structure. (Includes pieces of API v2 by Matt.)

* client: switch ll_* methods to Inode* argumentsMatt Benjamin2013-09-042-188/+332
| | | | | | | | | | | | | | | | | This commit implements a set of API changes proposed by "David Zafman" <david.zafman@inktank.com>. The principle change is consistently use Ceph Inode pointers as context for inode operations, in place of materialized snapid, inode# (vinodeno_t) tuples. This provides a strictly handle-based interface to users. They can either do lookups themselves, or call a lookup method to get an Inode* from a vinodeno_t. (Build fixed in later commits, e.g., SyntheticClient.cc.) Signed-off-by: Matt Benjamin <matt@linuxbox.com>

* client: add barrier and typesMatt Benjamin2013-09-044-0/+326
| | | | | | | | | | | This gives us a framework to implement commit operations that are guaranteed to terminate even if unstable writes come in after commit is called. Adapted to use Boost interval classes by Adam Emerson <aemerson@linuxbox.com>. Signed-off-by: Matt Benjamin <matt@linuxbox.com>

| | | | | | | | | | | | | | | | | | | | | | | | Except in very special cases, we should let PaxosService take its course and trigger the proposals itself. In this case, we were proposing right before returning to PaxosService, and we were returning false on top of it (most likely to guarantee that PaxosService wouldn't try to propose). This doesn't make much sense, so let's do it like all the other cool kids are doing and let PaxosService decide what's best for us. Signed-off-by: Joao Eduardo Luis <jecluis@gmail.com>

If the src_version does not match the source object, or the source object is updated while the copy is in progress, we will fail with a suitable error code. By atomic we mean that it will either successfully copy the entire object in its entirety or it will fail (and require no cleanup). Add to C++ librados API only for now.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Following the changes to when we set or increase the user_version, we want to continue to return the best lower bound we can on the version of any newly-created object. For ENOENT replies that means returning info.last_user_version instead of the (potentially-zero) ctx->user_at_version. Similarly, for cls_current_version we want to return the last version on the PG rather than the last update to the object in order to provide sensible version ordering across object deletes and creates. Update the versions doc so it continues to be precise. Signed-off-by: Greg Farnum <greg@inktank.com> Reviewed-by: Sage Weil <sage@inktank.com>
