gcron: create the lockfile if it is missing

2018-06-20T17:38:45+00:00

The lockfile for the job may not exist yet. If that is the case, it
should be created upon the first time it is accessed.

gcron: catch OSError as well as IOError

2018-06-18T13:19:34+00:00

In case os.open() fails because the file does not exist, an OSError is
raised. To prevent the script to abort uncleanly, catch the OSError in
addition to the IOError.

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.

build: add --without-server option

2018-02-19T17:38:55+00:00

With Gluster 4.0 we will not provide the server components for EL6 and
older. At one point Gluster 4.x will get GlusterD2, which requires
Golang tools in the distribution. EL6 does not contain these at the
moment.

With this change, it is possible to `./configure --without-server` which
prevents building glusterd and the xlators for the bricks. Building RPMs
can pass `--without server` and the glusterfs-server sub-package will
not be created.

snapshot/scheduler: Set sebool cron_system_cronjob_use_shares to on

2017-02-22T06:11:15+00:00

Rhel 7.1 onwards, the user has to manually set the
selinux boolean 'cron_system_cronjob_use_shares' as
on, if selinux is enabled for snapshot scheduler to
work.

With this fix, we are automating that bit, in init step
of snapshot scheduler

snapshot/scheduler: Check if volume exists before adding/editing schedules

Before adding or editing a scheduler, check if the volume name provided
in the schedule, exists in the cluster or not.

Added return code VOLUME_DOES_NOT_EXIST(17) for the same.
