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
}

eventsapi: Add conditional import for requests library

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.

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.

eventsapi: Add support for Client side Events

2016-08-31T01:34:59+00:00

Client side gf_event uses ctx->cmd_args.volfile_server to push
notifications to the eventsd.

Socket server changed from Unix domain socket to UDP to support
external events.

Following to be addressed in different patch
- Port used for eventsd is 24009. Make it configurable
  Already configurable in Server side. Configurable in gf_event API
  is required.
- Auth Token yet to be added as discussed in

make 'eventtypes.py' as dependent i.e. must build eventtypes.h

Else the consequence will be like:

eventsapi: Fix disable-events issue

2016-08-24T08:23:06+00:00

Events related sources are not loaded in libglusterfs when
configure is run with --disable-events option. Due to this
every call of gf_event should be guarded with USE_EVENTS macro.

To prevent this, USE_EVENTS macro was included in events.c
itself(Patch #15054)

Instead of disabling building entire directory "events", selectively
disabled the code. So that constants and empty function gf_event is
exposed. Code will not fail even if gf_event is called when events is
disabled.
