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.

Problem: 1) server_init does not cleanup allocate resources
while it is failed before return error
2) dict leak at the time of graph destroying
Solution: 1) free resources in case of server_init is failed
2) Take dict_ref of graph xlator before destroying
the graph to avoid leak

As an example, and also as an enhancement, added 'log-level' as a default option to every translator (glusterfs already support infrastructure to handle xl->loglevel). Corresponding infrastructure to add per xlator log-level is not present in glusterd volume-set. Plan is to get it sorted out in later patches or in GD2. * Why this is needed? - Mainly because we need to only add different log-level to some xlator to debug few things in a production system, while not changing overall log-level. This helps in better debug-ability. Updates: bz#1193929 Change-Id: Ia4098ce39197cd423345b3d31fe8315481681ab8 Signed-off-by: Amar Tumballi <amarts@redhat.com>
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

`doc/xlator-classification.md` talks about the reasoning and expectations Reviewers are expected to check the 'category' of new option / translator added in the codebase, and make sure the flag is always properly set. It helps to keep the 'expectation' proper on the codebase. updates: #430 Change-Id: I2bfc9934a5f6eed77fcc3e20364046242decc82c Signed-off-by: Amar Tumballi <amarts@redhat.com>
- Added kernel-writeback-cache command line and xlator
option for requesting utilisation of the writeback
cache of the kernel in FUSE_INIT (see [1]).
- Added attr-times-granularity command line and xlator
option via which granularity of the {a,m,c}time in
stat (attr) data that we support can be indicated to
kernel. This is a means to avoid divergence of the
attr times between kernel and userspace that could
occur with writeback-cache, while still maintaining
maximum time precision the FUSE server is capable of
(see [2]).
- Handling FATTR_CTIME flag in FUSE_SETATTR that
indicates presence of ctime in setattr payload.
Currently we cannot associate arbitrary ctimes to
files on backend, so we just touch them to update
their ctimes to current time. Having ctimes in setattr
payload is also a side effect of writeback cache
(see [3] and [4]).

Problem: glusterd2 build is failed due to undefined symbol
(xlator_mem_cleanup , glusterfsd_ctx) in server.so
Solution: To resolve the same done below two changes
1) Move xlator_mem_cleanup code from glusterfsd-mgmt.c
to xlator.c to be part of libglusterfs.so
2) replace glusterfsd_ctx to this->ctx because symbol
glusterfsd_ctx is not part of server.so

Problem: Sometimes brick process is getting crashed at the time
of stop brick while brick mux is enabled.
Solution: Brick process was getting crashed because of rpc connection
was not cleaning properly while brick mux is enabled.In this patch
after sending GF_EVENT_CLEANUP notification to xlator(server)
waits for all rpc client connection destroy for specific xlator.Once rpc
connections are destroyed in server_rpc_notify for all associated client
for that brick then call xlator_mem_cleanup for for brick xlator as well as
all child xlators.To avoid races at the time of cleanup introduce
two new flags at each xlator cleanup_starting, call_cleanup.

Problem: The values for inode/fd was populated from the ctx received from the server xlator. Without brickmux, every brick from a volume belonged to a single brick from the volume. So searching the server and populating it worked. With brickmux, a number of bricks can be confined to a single process. These bricks can be from different volumes too (if we use the max-bricks-per-process option). If they are from different volumes, using the server xlator to populate causes problem. Fix: Use the brick to validate and populate the inode/fd status. Signed-off-by: hari gowtham <hgowtham@redhat.com> Change-Id: I2543fa5397ea095f8338b518460037bba3dfdbfd fixes: bz#1566067
