shebangs changed from /usr/bin/python2 to /usr/bin/python3.
(Reminder, various distribution packaging guidelines require use
of explicit python version and don't allow '#!/usr/bin/env python',
regardless of how handy that idiom may be.)

glusterfs.spec(.in) package python{2,3}-gluster and python2 or
python3 dependencies as appropriate.

configure(.ac):
+ test for and use python2 or python3 as appropriate. If build
  machine has python2 and python3, use python3. Override by
  setting PYTHON=/usr/bin/python2 when running configure.
+ PYTHONDEV_CPPFLAGS from python[23]-config --includes is a
  better match to the original python sysconfig.get_python_inc().
  All those other extraneous flags breaks the build.
+ Only change the shebangs once. Changing them over and over
  again, e.g., during a `make glusterrpms` in extras/LinuxRPM
  just sends make (is it really make that's looping?) into an
  infinite loop. If you figure out why, let me know.
+ Oldest python2 is python2.6 on CentOS 6 and Debian 8 (Jessie).
  Everything else has 2.7 or 3.x
+ logic from https://review.gluster.org/c/glusterfs/+/21050, which
  needs to be removed/merged after that patch is merged.

Builds on CentOS 6, CentOS 7, Fedora 28, Fedora rawhide, and the
mysterious RHEL > 7.

core/build/various: python3 compat, prepare for python2 -> python3

2018-04-12T11:04:27+00:00

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.

eventsapi: HTTPS support for Webhooks

2017-10-31T06:46:56+00:00

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 support

2017-10-13T11:17:39+00:00

New argument added to accept secret to generate JWT token. This patch
does not affect the backward compatibility.

Usage:

    gluster-eventsapi webhook-add  [-t ] \
        [-s SECRET]

With `--token` argument, Token header will be added as is.

    Authorization: Bearer 

In case of shared secret, Gluster will generate JWT token using the
secret and then add it to Authorization header.

    Authorization: Bearer 

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

eventsapi: Fix webhook-test when no schema specified in URL

2017-04-17T10:25:27+00:00

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: Add Init scripts for different distributions

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

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 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
  https://www.gluster.org/pipermail/gluster-devel/2016-August/050324.html
