From d41cc82d11076a4f447ee13837ef2b0f7591642f Mon Sep 17 00:00:00 2001 From: Chad Smith Date: Fri, 20 Jul 2018 11:50:42 +0000 Subject: get_linux_distro: add support for centos6 and rawhide flavors of redhat An empty /etc/os-release exists on some redhat images, most notably the COPR build images of centos6 and rawhide. On platforms missing /etc/os-release or having an empty /etc/os-release file, use _parse_redhat_release on rhel-based images to obtain distribution and release codename information.

16:02:25 +0000 Subject: tests: Disallow use of util.subp except for where needed. MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit In many cases, cloud-init uses 'util.subp' to run a subprocess. This is not really desirable in our unit tests as it makes the tests dependent upon existance of those utilities. The change here is to modify the base test case class (CiTestCase) to raise exception any time subp is called. Then, fix all callers. For cases where subp is necessary or actually desired, we can use it via   a.) context hander CiTestCase.allow_subp(value)   b.) class level self.allowed_subp = value Both cases the value is a list of acceptable executable names that will be called (essentially argv[0]). Some cleanups in AltCloud were done as the code was being updated. --- cloudinit/analyze/tests/test_dump.py | 86 ++++++++------------ cloudinit/cmd/tests/test_status.py | 6 +- cloudinit/config/tests/test_snap.py | 7 +- cloudinit/config/tests/test_ubuntu_advantage.py | 7 +- cloudinit/net/tests/test_init.py | 2 + cloudinit/sources/DataSourceAltCloud.py | 24 +++--- cloudinit/sources/DataSourceSmartOS.py | 29 ++++--- cloudinit/tests/helpers.py | 43 ++++++++++ tests/unittests/test_datasource/test_altcloud.py | 44 +++++----- tests/unittests/test_datasource/test_cloudsigma.py | 3 + .../unittests/test_datasource/test_configdrive.py | 3 + tests/unittests/test_datasource/test_nocloud.py | 2 + tests/unittests/test_datasource/test_opennebula.py | 1 + tests/unittests/test_datasource/test_ovf.py | 8 +- tests/unittests/test_datasource/test_smartos.py | 94 +++++++++++++++------- tests/unittests/test_ds_identify.py | 1 + .../test_handler/test_handler_apt_source_v3.py | 11 ++- .../unittests/test_handler/test_handler_bootcmd.py | 10 ++- tests/unittests/test_handler/test_handler_chef.py | 18 +++-- .../test_handler/test_handler_resizefs.py | 8 +- tests/unittests/test_handler/test_schema.py | 12 ++- tests/unittests/test_net.py | 18 ++++- tests/unittests/test_util.py | 27 ++++--- 23 files changed, 289 insertions(+), 175 deletions(-) (limited to 'cloudinit/tests') diff --git a/cloudinit/analyze/tests/test_dump.py b/cloudinit/analyze/tests/test_dump.py index f4c42841..db2a667b 100644 --- a/cloudinit/analyze/tests/test_dump.py +++ b/cloudinit/analyze/tests/test_dump.py @@ -5,8 +5,8 @@ from textwrap import dedent from cloudinit.analyze.dump import ( dump_events, parse_ci_logline, parse_timestamp) -from cloudinit.util import subp, write_file -from cloudinit.tests.helpers import CiTestCase +from cloudinit.util import which, write_file +from cloudinit.tests.helpers import CiTestCase, mock, skipIf class TestParseTimestamp(CiTestCase): @@ -15,21 +15,9 @@ class TestParseTimestamp(CiTestCase): """Logs with cloud-init detailed formats will be properly parsed.""" trusty_fmt = '%Y-%m-%d %H:%M:%S,%f' trusty_stamp = '2016-09-12 14:39:20,839' - - parsed = parse_timestamp(trusty_stamp) - - # convert ourselves dt = datetime.strptime(trusty_stamp, trusty_fmt) - expected = float(dt.strftime('%s.%f')) - - # use date(1) - out, _err = subp(['date', '+%s.%3N', '-d', trusty_stamp]) - timestamp = out.strip() - date_ts = float(timestamp) - - self.assertEqual(expected, parsed) - self.assertEqual(expected, date_ts) - self.assertEqual(date_ts, parsed) + self.assertEqual( + float(dt.strftime('%s.%f')), parse_timestamp(trusty_stamp)) def test_parse_timestamp_handles_syslog_adding_year(self): """Syslog timestamps lack a year.

When this header exists, the cloud-config or script will be rendered as a jinja template. All instance metadata keys and values present in /run/cloud-init/instance-data.json will be available as jinja variables for the template. This means any cloud-config module or script can reference any standardized instance data in templates and scripts. Additionally, any standardized instance-data.json keys scoped below a '' key will be promoted as a top-level key for ease of reference in templates. This means that '{{ local_hostname }}' is the same as using the latest '{{ v#.local_hostname }}'. Since instance-data is written to /run/cloud-init/instance-data.json, make sure it is persisted across reboots when the cached datasource opject is reloaded.
