* core/build/various: python3 compat, prepare for python2 -> python3Kaleb S. KEITHLEY2018-04-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | Note 1) we're not supposed to be using #!/usr/bin/env python, see https://fedoraproject.org/wiki/Packaging:Guidelines?rd=Packaging/Guidelines#Shebang_lines Note 2) we're also not supposed to be using "!/usr/bin/python, see https://fedoraproject.org/wiki/Changes/Avoid_usr_bin_python_in_RPM_Build#Quick_Opt-Out The previous patch (https://review.gluster.org/19767) tried to do too much in one patch, so it was abandoned. This patch does two things: 1) minor cleanup of configure(.ac) to explicitly use python2 2) change all the shebang lines to #!/usr/bin/python2 and add them where they were missing based on warnings emitted during rpmbuild. In a follow-up patch python2 will eventually be changed to python3. Before that python2-isms (e.g. print, string.join(), etc.) need to be converted to python3. Some of those can be rewritten in version agnostic python. E.g. print statements become print() with "from __future_ import print_function". The python 2to3 utility will be used for some of those. Also Aravinda has given guidance in the comments to the first patch for changes. updates: #411 Change-Id: I471730962b2526022115a1fc33629fb078b74338 Signed-off-by: Kaleb S.

* eventsapi: Push Messages to Webhooks in parallelAravinda VK2016-12-021-0/+2
| | | | | | | | | | | | | | | | | | 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 convert Boolean and Int attributesAravinda VK2016-10-191-1/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 } BUG: 1379328 Change-Id: Iabc51fd61abc267a7c8dcf0aeac6b3c722d89649 Signed-off-by: Aravinda VK <avishwan@redhat.com> Reviewed-on: http://review.gluster.org/15574 NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Prashanth Pai <ppai@redhat.com> Smoke: Gluster Build System <jenkins@build.gluster.org>
* eventsapi: Add Init scripts for different distributionsAravinda VK2016-09-091-3/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Added init scripts for - SysvInit(CentOS 6 or Red Hat 6) - rc.d (FreeBSD) Most of the latest distributions are using systemd. Support to be added for other distributions which are not using systemd. Removed systemctl wrapper functions(start/stop/status) from 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.

* eventsapi: Add support for Client side EventsAravinda VK2016-08-301-72/+23
| | | | | | | | | | | | | | | | | | | | | | | | | 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 https://www.gluster.org/pipermail/gluster-devel/2016-August/050324.html Change-Id: I159acf80b681d10b82d52cfb3ffdf85cb896542d BUG: 1367774 Signed-off-by: Aravinda VK <avishwan@redhat.com> Reviewed-on: http://review.gluster.org/15189 Smoke: Gluster Build System <jenkins@build.gluster.org> Reviewed-by: Prashanth Pai <ppai@redhat.com> Reviewed-by: Atin Mukherjee <amukherj@redhat.com> CentOS-regression: Gluster Build System <jenkins@build.gluster.org> NetBSD-regression: NetBSD Build System <jenkins@build.gluster.org>
* eventsapi: Gluster Eventing Feature implementationAravinda VK2016-07-181-0/+151
[Depends on http://review.gluster.org/14627] Design is available in `glusterfs-specs`, A change from the design is support of webhook instead of Websockets as discussed in the design http://review.gluster.org/13115 Since Websocket support depends on REST APIs, I will add Websocket support once REST APIs patch gets merged Usage: Run following command to start/stop Eventsapi server in all Peers, which will collect the notifications from any Gluster daemon and emits to configured client. gluster-eventsapi start|stop|restart|reload Status of running services can be checked using, gluster-eventsapi status Events listener is a HTTP(S) server which listens to events emited by the Gluster. Create a HTTP Server to listen on POST and register that URL using, gluster-eventsapi webhook-add <URL> [--bearer-token <TOKEN>] For example, if HTTP Server running in `http://192.168.122.188:9000` then add that URL using, gluster-eventsapi webhook-add http://192.168.122.188:9000 If it expects a Token then specify it using `--bearer-token` or `-t` We can also test Webhook if all peer nodes can send message or not using, gluster-eventsapi webhook-test <URL> [--bearer-token <TOKEN>] Configurations can be viewed/updated using, gluster-eventsapi config-get [--name] gluster-eventsapi config-set <NAME> <VALUE> gluster-eventsapi config-reset <NAME|all> If any one peer node was down during config-set/reset or webhook modifications, Run sync command from good node when a peer node comes back. Automatic update is not yet implemented. gluster-eventsapi sync Basic Events Client(HTTP Server) is included with the code, Start running the client with required port and start listening to the events. /usr/share/glusterfs/scripts/eventsdash.py --port 8080 Default port is 9000, if no port is specified, once it started running then configure gluster-eventsapi to send events to that client. Eventsapi Client can be outside of the Cluster, it can be run event on Windows. But only requirement is the client URL should be accessible by all peer nodes.(Or ngrok(https://ngrok.com) like tools can be used) Events implemented with this patch, - Volume Create - Volume Start - Volume Stop - Volume Delete - Peer Attach - Peer Detach It is easy to add/support more events, since it touches Gluster cmd code and to avoid merge conflicts I will add support for more events once this patch merges.
