The `manila.test` Module¶

The `manila.utils` Module¶

Utilities and helper functions.

class ComparableMixin: Bases: object

class IsAMatcher(expected_value=None): Bases: object

class LazyPluggable(pivot, **backends)

Bases: object

A pluggable backend loaded lazily based on some value.

class SSHPool(ip, port, conn_timeout, login, password=None, privatekey=None, *args, **kwargs)

Bases: eventlet.pools.Pool

A simple eventlet pool to hold ssh connections.

create()

get()

Return an item from the pool, when one is available.

This may cause the calling greenthread to block. Check if a connection is active before returning it. For dead connections create and return a new connection.

remove(ssh): Close an ssh client and remove it from free_items.

check_ssh_injection(cmd_list)

cidr_to_netmask(cidr): Convert cidr to netmask.

delete_if_exists(pathname): Delete a file, but ignore file not found error.

ensure_tree(path)

Create a directory (and any ancestor directories required)

Parameters:	path – Directory to create

execute(*cmd, **kwargs): Convenience wrapper around oslo’s execute() function.

file_open(*args, **kwargs)

Open file

see built-in file() documentation for more details

Note: The reason this is kept in a separate module is to easily: be able to provide a stub module that doesn’t alter system state at all (for unit tests)

get_from_path(items, path)

Returns a list of items matching the specified path.

Takes an XPath-like expression e.g. prop1/prop2/prop3, and for each item in items, looks up items[prop1][prop2][prop3]. Like XPath, if any of the intermediate results are lists it will treat each list item individually. A ‘None’ in items or any child expressions will be ignored, this function will not throw because of None (anywhere) in items. The returned list will contain no None values.

is_eventlet_bug105()

Check if eventlet support IPv6 addresses.

See https://bitbucket.org/eventlet/eventlet/issue/105

Return type:	bool

is_ipv6_configured()

Check if system contain IPv6 capable network interface.

Return type:	bool
Raises:	IOError

is_valid_ip_address(ip_address, ip_version)

monkey_patch()

Patch decorator.

If the Flags.monkey_patch set as True, this function patches a decorator for all functions in specified modules. You can set decorators for each modules using CONF.monkey_patch_modules. The format is “Module path:Decorator function”. Example: ‘manila.api.ec2.cloud:’ manila.openstack.common.notifier.api.notify_decorator’

Parameters of the decorator is as follows. (See manila.openstack.common.notifier.api.notify_decorator)

name - name of the function function - object of the function

read_cached_file(filename, cache_info, reload_func=None)

Read from a file if it has been modified.

Parameters:	cache_info – dictionary to hold opaque cache. reload_func – optional function to be called with data when file is reloaded due to a modification.
Returns:	data from file

read_file_as_root(file_path): Secure helper to read file as root.

require_driver_initialized(func)

retry(exception, interval=1, retries=10, backoff_rate=2, wait_random=False)

A wrapper around retrying library.

This decorator allows to log and to check ‘retries’ input param. Time interval between retries is calculated in the following way: interval * backoff_rate ^ previous_attempt_number

Parameters:

exception – expected exception type. When wrapped function raises an exception of this type, the function execution is retried.
interval – param ‘interval’ is used to calculate time interval between retries: interval * backoff_rate ^ previous_attempt_number
retries – number of retries.
backoff_rate – param ‘backoff_rate’ is used to calculate time interval between retries: interval * backoff_rate ^ previous_attempt_number
wait_random – boolean value to enable retry with random wait timer.

service_is_up(service): Check whether a service is up based on last heartbeat.

tempdir(*args, **kwds)

temporary_chown(*args, **kwds)

Temporarily chown a path.

Params owner_uid:
	UID of temporary owner (defaults to current user)

translate_string_size_to_float(string, multiplier='G')

Translates human-readable storage size to float value.

Supported values for ‘multiplier’ are following:

returns:

float if correct input data provided
None if incorrect

trycmd(*args, **kwargs): Convenience wrapper around oslo’s trycmd() function.

validate_service_host(context, host)

wait_for_access_update(context, db, share_instance, migration_wait_access_rules_timeout)

walk_class_hierarchy(clazz, encountered=None): Walk class hierarchy, yielding most derived classes first.

The `manila.wsgi` Module¶

Utility methods for working with WSGI servers.

class Application

Bases: object

Base WSGI application wrapper. Subclasses need to implement __call__.

classmethod factory(global_config, **local_config)

Used for paste app factories in paste.deploy config files.

Any local configuration (that is, values under the [app:APPNAME] section of the paste config) will be passed into the __init__ method as kwargs.

A hypothetical configuration would look like:

[app:wadl] latest_version = 1.3 paste.app_factory = manila.api.fancy_api:Wadl.factory

which would result in a call to the Wadl class as

import manila.api.fancy_api fancy_api.Wadl(latest_version=‘1.3’)

You could of course re-implement the factory method in subclasses, but using the kwarg passing it shouldn’t be necessary.

class Debug(application)

Bases: manila.wsgi.Middleware

Helper class for debugging a WSGI application.

Can be inserted into any WSGI application chain to get information about the request and response.

static print_generator(app_iter): Iterator that prints the contents of a wrapper string.

class Loader(config_path=None)

Bases: object

Used to load WSGI applications from paste configurations.

load_app(name)

Return the paste URLMap wrapped WSGI application.

Parameters:	name – Name of the application to load.
Returns:	Paste URLMap object wrapping the requested application.
Raises:	manila.exception.PasteAppNotFound

class Middleware(application)

Bases: manila.wsgi.Application

Base WSGI middleware.

These classes require an application to be initialized that will be called next. By default the middleware will simply call its wrapped app, or you can override __call__ to customize its behavior.

classmethod factory(global_config, **local_config)

Used for paste app factories in paste.deploy config files.

Any local configuration (that is, values under the [filter:APPNAME] section of the paste config) will be passed into the __init__ method as kwargs.

A hypothetical configuration would look like:

[filter:analytics] redis_host = 127.0.0.1 paste.filter_factory = manila.api.analytics:Analytics.factory

which would result in a call to the Analytics class as

import manila.api.analytics analytics.Analytics(app_from_paste, redis_host=‘127.0.0.1’)

You could of course re-implement the factory method in subclasses, but using the kwarg passing it shouldn’t be necessary.

process_request(req)

Called on each request.

If this returns None, the next application down the stack will be executed. If it returns a response then that response will be returned and execution will stop here.

process_response(response): Do whatever you’d like to the response.

class Request(environ, charset=None, unicode_errors=None, decode_param_names=None, **kw): Bases: webob.request.Request

class Router(mapper)

Bases: object

WSGI middleware that maps incoming requests to WSGI apps.

class Server(name, app, host=None, port=None, pool_size=None, protocol=<class eventlet.wsgi.HttpProtocol>, backlog=128)

Bases: oslo_service.service.ServiceBase

Server class to manage a WSGI server, serving a WSGI application.

default_pool_size = 1000

host

port

reset()

Reset server greenpool size to default.

Returns:	None

start()

Start serving a WSGI application.

Returns:	None
Raises:	manila.exception.InvalidInput

stop()

Stop this server.

This is not a very nice action, as currently the method by which a server is stopped is by killing its eventlet.

Returns:	None

wait()

Block, until the server has stopped.

Waits on the server’s eventlet to finish, then returns.

Returns:	None
