all: Simplify component message id's definition

2017-12-14T02:33:51+00:00

This patch creates a new way of defining message id's that is easier
and less error prone because it doesn't require so many manual changes
each time a new component is defined or a new message created.

glusterfsd: making parent process to write pidfile while forking

2017-11-12T06:38:25+00:00

Issue: pid is written into glusterd.pid by child process instead of
parent process while forking.

Fix: After fork returns child pid to parent process, it falls under
default case of switch statement, call glusterfs_pidfile_update()
in default case instead of postfork label.

stack.h:PW.INCLUDE_RECURSION

2017-09-29T07:46:53+00:00

The headerfile globals.h is recursively adding itself.
( globals.h -> xlator.h -> stack.h -> globals.h).
We are finding the source files which are including the header
file globals.h and removing the inclusion line.

I used git grep -l stack.h | xargs git grep globals.h --
to find out the files and removed the header file from all files
except libglusterfs/src/xlator.h and libglusterfs/src/Makefile.am

When I try to remove header file from libglusterfs/src/xlator.h
I'm getting some errors. In libglusterfs/src/Makefile.am it is
required for building RPMs.

Glusterfsd: Unreachable statements

2017-09-26T13:06:33+00:00

Issue: Event unreachable at line number 1111 in glusterfsd/src/glusterfsd.c

There was a statement in outer if block after the break statement.
Ideally the break statement should be inside the inner if block so
that the statement will not become unreachable. I put the break
inside the inner if block.

mount/fuse: Make event-history feature configurable

2017-09-24T06:22:07+00:00

... and disable it by default.

This is because having it disabled seems to improve performance.
This could be due to the lock contention by the different epoll threads
on the circular buff lock in the fop cbks just before writing their response
to /dev/fuse.

Just to provide some data - wrt ovirt-gluster hyperconverged
environment, I saw an increase in IOPs by 12K with event-history
disabled for randrom read workload.

Usage:
mount -t glusterfs -o event-history=on $HOSTNAME:$VOLNAME $MOUNTPOINT
OR
glusterfs --event-history=on --volfile-server=$HOSTNAME --volfile-id=$VOLNAME $MOUNTPOINT
