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.

core: glusterfsd keeping fd open in index xlator

2018-10-08T15:45:47+00:00

Problem: Current resource cleanup sequence is not
         perfect while brick mux is enabled

Solution: 1) Destroying xprt after cleanup all fd associated
             with a client
          2) Before call fini for brick xlators ensure no stub
             should be running on a brick

glusterfsd: Sometime brick process is crashed after enable brick mux

2017-06-07T15:42:14+00:00

Problem: glusterfsd is getting Segfault while running bug-1432542-mpx-restart-crash.t
         in a loop in while brick mux is enabled.

Solution: Change the index_worker code as well as notify code in index.c
          to cleanup index_worker thread appropriately.

glusterfs: Not able to mount running volume after enable brick mux and stopped any volume

2017-05-31T20:43:53+00:00

Problem: After enabled brick mux if any volume has down and then try ot run mount
         with running volume , mount command is hung.

Solution: After enable brick mux server has shared one data structure server_conf
          for all associated subvolumes.After down any subvolume in some
          ungraceful manner (remove brick directory) posix xlator sends
          GF_EVENT_CHILD_DOWN event to parent xlatros and server notify
          updates the child_up to false in server_conf.When client is trying
          to communicate with server through mount it checks conf->child_up
          and it is FALSE so it throws message "translator are not yet ready".
          From this patch updated structure server_conf to save child_up status
          for xlator wise. Another improtant correction from this patch is
          cleanup threads from server side xlators after stop the volume.

features/index: Do deletion of name-index in unwind path

2016-06-24T04:14:08+00:00

Previously the deletion of name index was being done before
winding the xattrop to posix. This order needs to be changed
to ensure we don't lose the index in the event the xattrop fails
in posix xl.

index: improve compiler warning fix

2016-05-23T08:13:27+00:00

Commit 137bd83029458ecd461718a891c74cd1afd8f6cb introduced some
typecasting to work around a compiler warning. It is much cleaner to
add a -1 value in the enumeration and use that in if-statements.

features/index : Readdirp performance improvement

2015-11-25T03:06:02+00:00

Things done :
Index now maintains two different directories :
1) for pending xattrs (trusted.afr.volname-client-n,
                       trusted.ec.dirty)

2) for on going xattrs (trusted.afr.dirty)

Based on the xattr, index decides the directory
to add/del entry in/from.
