* libglusterfs: Move devel headers under glusterfs directoryShyamsundarR2018-12-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | libglusterfs devel package headers are referenced in code using include semantics for a program, this while it works can be better especially when dealing with out of tree xlator builds or in general out of tree devel package usage. Towards this, the following changes are done, - moved all devel headers under a glusterfs directory - Included these headers using system header notation <> in all code outside of libglusterfs - Included these headers using own program notation "" within libglusterfs This change although big, is just moving around the headers and making it correct when including these headers from other sources. This helps us correctly include libglusterfs includes without namespace conflicts.

* features/shard: Perform shards deletion in the backgroundKrutika Dhananjay2018-06-201-2/+4
| | | | | | | | | | | | | | | A synctask is created that would scan the indices from .shard/.remove_me, to delete the shards associated with the gfid corresponding to the index bname and the rate of deletion is controlled by the option features.shard-deletion-rate whose default value is 100. The task is launched on two accounts: 1. when shard receives its first-ever lookup on the volume 2. when a rename or unlink deleted an inode Change-Id: Ia83117230c9dd7d0d9cae05235644f8475e97bc3 updates: bz#1568521 Signed-off-by: Krutika Dhananjay <kdhananj@redhat.com>
* features/shard: Introducing ".shard/.remove_me" for atomic shard deletion ↵Krutika Dhananjay2018-06-131-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | (part 1) PROBLEM: Shards are deleted synchronously when a sharded file is unlinked or when a sharded file participating as the dst in a rename() is going to be replaced. The problem with this approach is it makes the operation really slow, sometimes causing the application to time out, especially with large files. SOLUTION: To make this operation atomic, we introduce a ".remove_me" directory. Now renames and unlinks will simply involve two steps: 1. creating an empty file under .remove_me named after the gfid of the file participating in unlink/rename 2. carrying out the actual rename/unlink A synctask is created (more on that in part 2) to scan this directory after every unlink/rename operation (or upon a volume mount) and clean up all shards associated with it. All of this happens in the background. The task takes care to delete the shards associated with the gfid in .remove_me only if this gfid doesn't exist in backend, ensuring that the file was successfully renamed/unlinked and its shards can be discarded now safely.

* all: Simplify component message id's definitionXavier Hernandez2017-12-141-167/+30
| | | | | | | | | This patch creates a new way of defining message id's that is easier and less error prone because it doesn't require so many manual changes each time a new component is defined or a new message created.
