libglusterfs: Move devel headers under glusterfs directory

2018-12-05T21:47:04+00:00

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.

locks: added inodelk/entrylk contention upcall notifications

2018-01-16T10:37:22+00:00

The locks xlator now is able to send a contention notification to
the current owner of the lock.

This is only a notification that can be used to improve performance
of some client side operations that might benefit from extended
duration of lock ownership. Nothing is done if the lock owner decides
to ignore the message and to not release the lock. For forced
release of acquired resources, leases must be used.

ec: Invalidations in disperse volume should not update the stat

2017-01-06T05:12:18+00:00

Issue:
In disperse volume, the file is present across bricks, hence the stat
from one brick doesn't carry the valid size of the file. Therefore
the upcall from one brick updating the md-cache results in wrong size
being updated.

Fix:
If the notification is cache invalidation then, indicate md-cache that
the attributes is invalid.

dht/md-cache: Filter invalidate if the file is made a linkto file

2016-12-02T10:46:58+00:00

Upcall as a part of setattr, sends an invalidation and the
invalidation carries the resulting stat value. When a file
is converted to linkto files, even then an invalidation
is set and as a result the mountpoint shows the sticky
bit in the stat of the file.
eg: ---------T. 945 root root 0 Nov  8 10:14 hardlink.999

Fix:
When dht recieves a notification of sticky bit change, it updates
the flag, to indicate md-cache to send the subsequent lookup.

upcall: Add permission change flag to iatt flag

2016-08-29T12:15:15+00:00

Currently IATT_UPDATE_FLAGS is (UP_NLINK | UP_MODE | UP_OWN | UP_SIZE |
UP_TIMES | UP_ATIME). But it should also have UP_PERM and permission bits
are apart of IATT.

This change will have no effect on the existing users as
IATT_UPDATE_FLAGS is currently used only by md-cache. And the changes in
md-cache to consume cache invalidation is not part of any release yet.

protocol: Add framework to send transaction id with recall

2016-06-10T11:03:40+00:00

Issue:
The upcall(cache invalidation/recall) event is sent from the bricks
to clients. In AFR/EC setup, it can so happen that all the bricks
will send the upcall for the same event, and if AFR/EC doesn't filter
out these duplicate notifications, the logic above cluster xlators
can fail.

Solution:
Use transaction id to filter out duplicate notifications.

This patch adds framework for duplicate notifications.
AFR/EC can build up on this patch for deduping the notifications

upcall: pass dict with xattrs on xattr invalidation

In case of xattr invalidation, return a dict containing
the updated xattrs.

[ndevos: move chunks to change 12995 and only address the xattrs-dict here]

upcall: Add support to invalidate xattrs

2016-05-11T18:23:00+00:00

When SElinux is used, clients should get a notification that the
extended attributes have been updated. Other components (like md-cache)
will be able to use this too.

A big part of the implementation comes from Poornima through the first
version of http://review.gluster.org/12996.

Also moving the flags from upcall-cache-invalidation.h to the main
libglusterfs upcall-utils.h file, so that other places can easily use
them in future.
