[Spacewalk-list] Systems Requiring Reboot

[Stephan Duehr]

Hi,

no such API method exists as far as I know.

A workaround could be to use the API method for getting
the running kernel (system.getRunningKernel) and compare
that somehow with the latest installed kernel package.
You could use system.listPackages to get all
installed packages and the lookup the installed kernel
packages in the result.

Some experiment, to show how it could be done:

>>> import pprint
>>> pp=pprint.PrettyPrinter(indent=4)
>>> sys_id = 1000010435
>>> running_kernel = client.system.getRunningKernel(session, sys_id)
>>> installed_kernels = [pkg for pkg in client.system.listPackages(session, sys_id) if pkg['name'] == 'kernel']
>>> pp.pprint(installed_kernels)
[   {   'arch': 'AMD64',
        'epoch': ' ',
        'installtime': <DateTime '20140724T08:37:54' at 1677f38>,
        'name': 'kernel',
        'release': '431.el6',
        'version': '2.6.32'},
    {   'arch': 'AMD64',
        'epoch': ' ',
        'installtime': <DateTime '20140724T08:45:54' at 1677f80>,
        'name': 'kernel',
        'release': '431.20.3.el6',
        'version': '2.6.32'},
    {   'arch': 'AMD64',
        'epoch': ' ',
        'installtime': <DateTime '20140729T09:09:18' at 1677fc8>,
        'name': 'kernel',
        'release': '431.20.5.el6',
        'version': '2.6.32'},
    {   'arch': 'AMD64',
        'epoch': ' ',
        'installtime': <DateTime '20140805T08:23:18' at 1682050>,
        'name': 'kernel',
        'release': '431.23.3.el6',
        'version': '2.6.32'}]
>>> latest_installed_kernel = None
>>> for ik in installed_kernels:
...     if not client.system.listNewerInstalledPackages(session, sys_id, ik['name'], ik['version'], ik['release'], ik['epoch']):
...         latest_installed_kernel = ik
...         break
...
>>> pp.pprint(latest_installed_kernel)
{   'arch': 'AMD64',
    'epoch': ' ',
    'installtime': <DateTime '20140805T08:23:18' at 1682050>,
    'name': 'kernel',
    'release': '431.23.3.el6',
    'version': '2.6.32'}
>>> running_kernel
'2.6.32-431.23.3.el6.x86_64'
>>> system_arch = client.system.getCpu(session, sys_id)['arch']
>>> system_arch
'x86_64'
>>> if running_kernel == '%s-%s.%s' % (latest_installed_kernel['version'], latest_installed_kernel['release'], system_arch):
...     print "no reboot required"
... else:
...     print "reboot required"
...
no reboot required

Now after installing a newer kernel packages was installed:

>>> installed_kernels = [pkg for pkg in client.system.listPackages(session, sys_id) if pkg['name'] == 'kernel']
>>> latest_installed_kernel = None
>>> for ik in installed_kernels:
...     if not client.system.listNewerInstalledPackages(session, sys_id, ik['name'], ik['version'], ik['release'], ik['epoch']):
...         latest_installed_kernel = ik
...         break
...
>>> pp.pprint(latest_installed_kernel)
{   'arch': 'AMD64',
    'epoch': ' ',
    'installtime': <DateTime '20141002T14:53:37' at 1675290>,
    'name': 'kernel',
    'release': '431.29.2.el6',
    'version': '2.6.32'}
>>> system_arch = client.system.getCpu(session, sys_id)['arch']
>>> if running_kernel == '%s-%s.%s' % (latest_installed_kernel['version'], latest_installed_kernel['release'], system_arch):
...     print "no reboot required"
... else:
...     print "reboot required"
...
reboot required

Stephan
