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.

rpc: bump up server.event-threads

2018-12-04T06:38:55+00:00

Problem:
A single event-thread causes performance issues in the system.

Solution:
Bump up event-threads to 2 to make the system more performant.
This helps in making the system more responsive and helps avoid the
ping-timer-expiry problem as well. However, setting the event-threads
to 2 is not the only thing required to avoid ping-timer-expiry issues.

glusterd: perform store operation in cleanup lock

2018-11-27T10:11:20+00:00

All glusterd store operation and cleanup thread should work under a
critical section to avoid any partial store write.

core: create a constant for default network timeout

2018-11-23T10:05:02+00:00

A new constant named GF_NETWORK_TIMEOUT has been defined and all
references to the hard-coded timeout of 42 seconds have been
replaced with this constant.

fuse: diagnostic FLUSH interrupt

2018-11-06T04:21:57+00:00

We add dummy interrupt handling for the FLUSH
fuse message. It can be enabled by the
"--fuse-flush-handle-interrupt" hidden command line
option, or "-ofuse-flush-handle-interrupt=yes"
mount option.

It serves no other than diagnostic & demonstational
purposes -- to exercise the interrupt handling framework
a bit and to give an usage example.

Documentation is also provided that showcases interrupt
handling via FLUSH.

glusterd: raise default transport.listen-backlog

2018-10-25T13:39:21+00:00

Problem:
data center setups with large number of bricks with replication
causes a flood of connections from bricks and self-heal daemons
to glusterd causing connections to be dropped due to insufficient
listener socket backlog queue length

Solution:
raise default value of transport.listen-backlog to 1024

glusterd/geo-rep: Fix memory corruption

2018-10-12T15:39:03+00:00

Problem and Analysis:
The length of canonical format of uuid is 36 but
'GF_UUID_BUF_SIZE 50' was being used everywhere.
glusterd/geo-rep code was earlier using strncpy,
but recently changes to memcpy with the drive
to avoid strncpys. This leads to memory corruption
and glusterd is crashing without a core with geo-rep
creation with ASAN build.

Fix:
'GF_UUID_BUF_SIZE 37' (+ 1 for NULL byte)
And change geo-rep to use UUID_CANONICAL_FORM_LEN
instead

New flag to glusterfsd binary to print libexec dir

2018-09-05T06:44:59+00:00

New CLI option for `glusterfsd` binary to get the path of
libexec directory. This helps glusterd2 to detect the
installed path of `gsyncd` and other binaries.

Usage: `glusterfsd --print-libexecdir`

posix: remove not supported get/set content

2018-09-04T12:27:15+00:00

getting and setting a file's content using extended
attribute worked great as a GET/PUT alternative when
an object storage is supported on top of Gluster. But
it needs application changes, and also, it skips some
caching layers. It is not used over years, and not
supported any more. Remove the dead code.
