build/packaging: Debian and Ubuntu don't have /usr/libexec

2017-03-13T14:18:07+00:00

GLUSTERFS_LIBEXECDIR is effectively hard-coded to /usr/libexec/glusterfs
in configure(.ac)

Debian-based distributions don't have a /usr/libexec/ directory

This issues is partially mitigated by the use of $libexecdir in
some of the Makefile.am files, but even so the incorrectly defined
GLUSTERFS_LIBEXECDIR results in various things such as gsyncd,
glusterfind, eventsd, etc., trying to invoke other scripts and
programs from a location that doesn't exist.

And once we correctly define GLUSTERFS_LIBEXECDIR, then we might as
well use it appropriatedly.

eventsapi: Push Messages to Webhooks in parallel

2016-12-02T14:52:55+00:00

With this patch, glustereventsd will maintain one thread per
webhook. If a webhook is slow, then all the events to that worker
will be delayed but it will not affect the other webhooks.

Note: Webhook in transit may get missed if glustereventsd reloads due to
new Webhook addition or due configuration changes.

eventsapi: Auto reload Webhooks data when modified

2016-11-17T11:10:25+00:00

glustereventsd depends on reload signal to reload the
Webhooks configurations. But if reload signal missed, no
events will be sent to newly added Webhook.

Added auto reload based on webhooks file mtime. Before pushing
events to Webhooks, reloads webhooks configurations if previously
recorded mtime is different than current mtime.

eventsapi: Auto convert Boolean and Int attributes

2016-10-20T06:10:44+00:00

Before publishing in JSON format, automatically convert the
attribute to "bool" or "int" if configured.

For example, instead of sending force="1", convert to bool and
send as force=True

{
    "event": "VOLUME_START",
    "name" : "gv1",
    "force": "1"
}

Convert to,

{
    "event": "VOLUME_START",
    "name" : "gv1",
    "force": true
}

2016-09-09T12:59:50+00:00

requests lib is used only during publishing event. gf_event python
imports utils.py, and indirectly imports requests lib even though
it is not required while sending event to eventsd.

Moved "import requests" inside the "plugin_webhook" function.

eventsapi: Add Init scripts for different distributions

2016-09-09T10:29:33+00:00

Added init scripts for
- SysvInit(CentOS 6 or Red Hat 6)

Most of the latest distributions are using systemd. Support to be
added for other distributions which are not using systemd.

gluster-eventsapi CLI(peer_eventsapi.py). Status and Reload
re-implemented using pid file check.

Added pid file support for glustereventsd.

Following dependencies removed
python-flask - Only used for example dashboard. User can install
if required.
python-fasteners - Not available for EPEL 6, added custom code using
fcntl as replacement.
