A predicate gates the collection of data by an sos plugin. For any
`add_cmd_output()`, `add_copy_spec()` or `add_journal()` call, the
passed predicate will be evaulated and collection will proceed if
the result is `True`, and not otherwise.
Predicates may be used to control conditional data collection
without the need for explicit conditional blocks in plugins.
:param owner: The ``Plugin`` object creating the predicate
:type owner: ``Plugin``
:param dry_run: Is sos running in dry_run mode?
:type dry_run: ``bool``
:param kmods: Kernel module name(s) to check presence of
:type kmods: ``list``, or ``str`` of single name
:param services: Service name(s) to check if running
:type services: ``list``, or ``str`` of single name
:param packages: Package name(s) to check presence of
:type packages: ``list``, or ``str`` of single name
:param cmd_outputs: Command to run, with output string to check
:type cmd_outputs: ``list`` of ``dict``s, or single ``dict`` taking form
{'cmd': <command to run>,
'output': <string that output should contain>}
:param arch: Architecture(s) that the local system is matched
against
:type arch: ``list``, or ``str`` of single architecture
:param required: For each parameter provided, should the checks
require all items, no items, or any items provided
:type required: ``dict``, with keys matching parameter names and values
being either 'any', 'all', or 'none. Default 'any'.

SoSCommanda� A class to represent a command to be collected.
A SoSCommand() object is instantiated for each command handed to an
_add_cmd_output() call, so that we no longer need to pass around a very
long tuple to handle the parameters.
Any option supported by _add_cmd_output() is passed to the SoSCommand
object and converted to an attribute. SoSCommand.__dict__ is then passed to
_get_command_output_now() for each command to be collected.

Checks to see if the plugin has hit its timeout.
This is set when the sos.collect_plugin() method hits a timeout and
terminates the thread. From there, a Popen() call can still continue to
run, and we need to manually terminate it. Thus, check_timeout() should
only be called in sos_get_command_output().
Since sos_get_command_output() is not plugin aware, this method is
handed to that call to use as a polling method, to avoid passing the
entire plugin object.

Plugins are generally representative of a single system component (e.g. kernel), package (e.g. podman), or similar construct. Plugins will typically specify multiple files or directories to copy, as well as commands to execute and collect the output of for further analysis.z
sos reportzPlugin Enablementz�Plugins will be automatically enabled based on one of several triggers - a certain package being installed, a command or file existing, a kernel module being loaded, etc...zXPlugins may also be enabled or disabled by name using the %s or %s options respectively.z-e $namez-n $namea( Certain plugins may only be available for specific distributions or may behave differently on different distributions based on how the component for that plugin is installed or how it operates. When using %s, help will be displayed for the version of the plugin appropriate for your distribution.z sos help report.plugins.$pluginzUsing Plugin OptionsaZ Many plugins support additional options to enable/disable or in some other way modify the collections it makes. Plugin options are set using the %s syntax. Options that are on/off toggles may exclude setting a value, which will be interpreted as enabling that option.
See specific plugin help sections or %s for more information on these optionsz#-k $plugin_name.$option_name=$valuez

`copyspecs` will be expanded and/or globbed as appropriate. Specifying
a directory here will cause the plugin to attempt to collect the entire
directory, recursively.
If `container` is specified, `copyspecs` may only be explicit paths,
not globs as currently container runtimes do not support glob expansion
as part of the copy operation.
Note that `sizelimit` is applied to each `copyspec`, not each file
individually. For example, a copyspec of
``['/etc/foo', '/etc/bar.conf']`` and a `sizelimit` of 25 means that
sos will collect up to 25MB worth of files within `/etc/foo`, and will
collect the last 25MB of `/etc/bar.conf`.

given the condition of the underlying environment.
The default implementation will return True if none of class.files,
class.packages, nor class.commands is specified. If any of these is
specified the plugin will check for the existence of any of the
corresponding paths, packages or commands and return True if any
are present.
For SCLPlugin subclasses, it will check whether the plugin can be run
for any of installed SCLs. If so, it will store names of these SCLs
on the plugin class in addition to returning True.
For plugins with more complex enablement checks this method may be
overridden.

dS )r a� Superclass for plugins operating on Software Collections (SCLs).
Subclasses of this plugin class can specify class.files and class.packages
using "%(scl_name)s" interpolation. The plugin invoking mechanism will try
to match these against all found SCLs on the system. SCLs that do match
class.files or class.packages are then accessible via self.scls_matched
when the plugin is invoked.
Additionally, this plugin class provides "add_cmd_output_scl" (run
a command in context of given SCL), and "add_copy_spec_scl" and
"add_copy_spec_limit_scl" (copy package from file system of given SCL).
For example, you can implement a plugin that will list all global npm
packages in every SCL that contains "npm" package:
class SCLNpmPlugin(Plugin, SCLPlugin):
packages = ("%(scl_name)s-npm",)
def setup(self):
for scl in self.scls_matched:
