* upcall: Update the access time in missing casesPoornima G2017-06-091-0/+36
| | | | | | | | | | | | | | | | | | Issue: In fops like rename, link, unlink etc, the parent dirrs' client access time was not being updated. And in fops like create, link, symlink etc. the new file/dirs' client access time was not updated. Solution: Update the client access time for both parent and new entry.

* marker: Fix inode value in loc, in setxattr fopPoornima G2017-02-201-0/+30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | On recieving a rename fop, marker_rename() stores the, oldloc and newloc in its 'local' struct, once the rename is done, the xtime marker(last updated time) is set on the file, but sending a setxattr fop. When upcall receives the setxattr fop, the loc->inode is NULL and it crashes. The loc->inode can be NULL only in one valid case, i.e. in rename case where the inode of new loc can be NULL. Hence, marker should have filled the inode of the new_loc before issuing a setxattr. marker_rename_cbk was already fixed in a previous commit. Fixing marker_rename_done to send valid inode in this commit. Also in upcall check for NULL inode so that there is no crash.

* tests: Fix one of the upcall testsPoornima G2016-09-021-2/+3
| | | | | | | | | | | | | | | | | Currently md-cache invalidation feature is enabled by setting "performance.cache-invalidation", but this case was sent when "features.cache-invalidation" was enabling md-cache invalidation. Hence, fix the same.

* io-stats: Add stats for upcall notificationsv3.10devPoornima G2016-08-311-0/+38
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With this patch, there will be additional entries seen in the profile info: UPCALL : Total number of upcall events that were sent from the brick(in brick profile), and number of upcall notifications recieved by client(in client profile) Cache invalidation events: ------------------------- CI_IATT : Number of upcalls that were cache invalidation and had one of the IATT_UPDATE_FLAGS set. This indicates that one of the iatt value was changed. CI_XATTR : Number of upcalls that were cache invalidation, and had one of the UP_XATTR or UP_XATTR_RM set. This indicates that an xattr was updated or deleted. CI_RENAME : Number of upcalls that were cache invalidation, resulted by the renaming of a file or directory CI_UNLINK : Number of upcalls that were cache invalidation, resulted by the unlink of a file. CI_FORGET : Number of upcalls that were cache invalidation, resulted by the forget of inode on the server side. Lease events: ------------ LEASE_RECALL : Number of lease recalls sent by the brick (in brick profile), and number of lease recalls recieved by client(in client profile) Note that the sum of CI_IATT, CI_XATTR, CI_RENAME, CI_UNLINK, CI_FORGET, LEASE_RECALL may not be equal to UPCALL. This is because, each cache invalidation can carry multiple flags. Eg: - Every CI_XATTR will have CI_IATT - Every CI_UNLINK will also increment CI_IATT as link count is an iatt attribute. Also UP_PARENT_DENTRY_FLAGS is currently not accounted for, as CI_RENAME and CI_UNLINK will always have the flag UP_PARENT_DENTRY_FLAGS Change-Id: Ieb8cd21dde2c4c7618f12d025a5e5156f9cc0fe9 BUG: 1371543 Signed-off-by: Poornima G <pgurusid@redhat.com> Reviewed-on: http://review.gluster.org/15193 Smoke: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> Reviewed-by: Rajesh Joseph <rjoseph@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Pranith Kumar Karampuri <pkarampu@redhat.com>
* upcall: Mark the clients as accessed on readdirp entriesPoornima G2016-08-311-0/+43
| | | | | | | | | | | | | | | | | | | | Currently when a client performs a readdirp it is not stored in upcall, as one of the clients that have accessed the files. Hence, when any other client modifies the file, the client that had performed readdirp will not get any notifications. Fix this by adding the clients to upcall database when they perform readdirp.

* Upcall/cache-invalidation: Ignore fops with frame->root->client not setSoumya Koduri2015-06-091-0/+29
Server-side internally generated fops like 'quota/marker' will not have any client associated with the frame. Hence we need a check for clients to be valid before processing for upcall cache invalidation. Also fixed an issue with initializing reaper-thread. Added a testcase to test the fix.
