rpcsvc: scale rpcsvc_request_handler threads

2018-03-20T12:17:40+00:00

Scale rpcsvc_request_handler threads to match the scaling of event
handler threads.

Please refer to https://bugzilla.redhat.com/show_bug.cgi?id=1467614#c51
for a discussion about why we need multi-threaded rpcsvc request
handlers.

build: address linkage issues

2018-03-06T13:43:53+00:00

We have the following undefined symbol error from protocol/server.so:

  glusterfs_mgmt_pmap_signout
  glusterfs_autoscale_threads

See https://review.gluster.org/19225 (bz#1532238)
and https://review.gluster.org/19657 (bz#1550895)

IMO this is a cleaner solution. I.e. moving the above two functions
to libgfrpc (.../rpc/rpc-lib/...)

I would also, for (foolish) consistency sake, like to see
glusterfs_mgmt_pmap_signin() moved from glusterfsd to libgfrpc as
well.

This works on f28/rawhide, with its new, more restrictive run-time
link semantics. The smoke and regression tests on earlier fedora and
centos will confirm that it works on those platforms too.

build: add --without-server option

2018-02-21T18:08:14+00:00

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

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.

rpc: merge ssl infra with epoll infra

2017-12-12T14:42:05+00:00

Patch attempts to use the epoll infra for handling SSL connections
as well instead of the socket_poller() thread func.
This essentially makes priv->own_thread flag redundant.

SSL_connect()/SSL_accept() is now non-blocking which has done away
with the localised poll() in ssl_do(). So, ssl_do() has been updated
appropriately.

own_thread and coincidently socket_poller() thread for SSL processing
is now deprecated.

Added a timeout to test whether seal-heal daemon is up and running
as per Ravi's suggestion.

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.
