* 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.

* all: Simplify component message id's definitionXavier Hernandez2017-12-141-81/+13
| | | | | | | | | 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.

* md-cache: Register the list of xattrs with cache-invalidationPoornima G2016-08-301-1/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Issue: md-cache caches a specified list of xattrs, and when cache invalidation is enabled, it makes sense to recieve invalidation only when those xattrs are modified by other clients. But the current implementation of upcall is that, it will send invalidation when any of the on-disk xattrs is modified. Solution: md-cache sends a list of xattrs that it is interested in, to upcall by issuing an ipc(). The challenge here is to make sure everytime a brick goes offline and comes back up, the ipc() needs to be issued to the bricks. Hence ipc() is sent from md-cache every time there is a CHILD_UP/CHILD_MODIFIED event. TODO: There will be patches following, in cluster xlators, to implement ipc fop.

* md-cache: Add cache invalidation support to invalidate the meta data cachePoornima G2016-07-201-1/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | Problem: md-cache currently updates its stat in cbks of selected fops. The default cache time is 1 second, if this is increasd to reap the benefits of caching, we may end up with stale cache for long time, as there is no logic yet to notify md-cache of backend changes by another client. Solution: Use the existing upcall mechanism to invalidate the cache. For this feature to work, "features.cache-invalidation" volume option should be enabled. This patch as is doesn't improve any performance, the benifit of the patch is that it provides coherency for stat cache, hence the cache timeout can be quite longer which in turn can improve the performance.
