57064765b7 msg: Give MPoolOpReply a bufferlist for reply data 2010-04-23 14:42:48 -07:00
Greg Farnum
503c41e6b1 mon: change the unmanaged snap interface for better distinction of reply codes 
and snapid numbers.

Of course, this now means that the snapid isn't actually passed
back to the client, but that is about to change.

5116700fdc msg: Add space for snapid in MPoolOp. Reply now uses an int64_t replyCode. 
This allows space for a full 64-bit snapid to be returned, which is about
to be necessary.

609eaa14ca mds: skip client snap notification on unlink 
This is cheating a bit, but should be harmless.  Basically, we spit off the
snaprealm when we unlink to keep the hierarchy vs snaprealm invariants
intact.  But we don't really care if the client does so, so we skip the
client_snap notifications.

That means the client will leave unlinked inodes in the realm they were
in at the time of unlink.  I'm pretty sure that won't cause problems
later.

5a5cc18374 osd: don't capture SIGINT/SIGTERM; journal and/or btrfs snaps are sufficient. 
We used to do this to avoid corrupting the filestore, but since we can now
either roll forward with the writeahead journal OR roll back using btrfs
snaps, this is useless.  It wasn't a full solution anyway.

1915f2d590 mds: clone dentry for multiversion dir if linkage is changing... 
...even if the inode itself doesn't need to be cowed.  In particular, we
do the pre_cow_old_inode() thing, so it frequently doesn't need to be cowed,
but the dentry does when we are say unlinking a directory or some such.
