* 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: HTTPS support for WebhooksAravinda VK2017-10-311-8/+40
| | | | | | | | | | | | | | | | | First it tries to call URL with verify=True without specifying the cert path, it succeeds if a webhook is HTTP or HTTPS with CA trusted certificates(for example https://github..). If above call fails with SSL error then it tries to get the server certificate and calls URL again. If call fails with SSL error even after using the certificate, then verification will be disabled and logged in the log file. All other errors will be catched and logged as usual.

* eventsapi: Add JWT signing supportAravinda VK2017-10-131-5/+35
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | New argument added to accept secret to generate JWT token. This patch does not affect the backward compatibility. Usage: gluster-eventsapi webhook-add <url> [-t <TOKEN>] \ [-s SECRET] With `--token` argument, Token header will be added as is. Authorization: Bearer <TOKEN> In case of shared secret, Gluster will generate JWT token using the secret and then add it to Authorization header. Authorization: Bearer <GENERATED_TOKEN> Secret/Token can be updated using `webhook-mod` command. Generated token will include the following payload, { "iss": "gluster", "exp": EXPIRY_TIME, "sub": EVENT_TYPE, "iat": EVENT_TIME } Where: iss - Issuer, exp - Expiry Time, sub - Event Type used as Subject, iat - Event Time used as Issue Time BUG: 1496363 Change-Id: Ib6b6fab23fb212d7f5e9bbc9e1416a9e9813ab1b Signed-off-by: Aravinda VK <avishwan@redhat.com>
* eventsapi: Fix webhook-test when no schema specified in URLAravinda VK2017-04-171-1/+3
| | | | | | | | | | | | | | | | | If no schema specifed like `http` or `https` while testing webhook, it was failing with Schema Exception and not communicated the error to CLI caller. With this patch exception is handled and responded back to CLI caller.

* eventsapi: JSON output and different error codesAravinda VK2016-12-021-83/+226
| | | | | | | | | | | | | | | | | | | | | | | | | | | | JSON outputs are added to all commands, use `--json` to get JSON output. Following error codes are added to differenciate between errors. Any other Unknown errors will have return code 1 ERROR_SAME_CONFIG = 2 ERROR_ALL_NODES_STATUS_NOT_OK = 3 ERROR_PARTIAL_SUCCESS = 4 ERROR_WEBHOOK_ALREADY_EXISTS = 5 ERROR_WEBHOOK_NOT_EXISTS = 6 ERROR_INVALID_CONFIG = 7 ERROR_WEBHOOK_SYNC_FAILED = 8 ERROR_CONFIG_SYNC_FAILED = 9 Also hidden `node-` commands in the help message.

* eventsapi: Add Init scripts for different distributionsAravinda VK2016-09-091-113/+47
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 VK2016-08-301-0/+4
| | | | | | | | | | | | | | | | | | | | | | | | | 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/+521
[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.
