aerunner – Aerunner

This module implements AERunner Class which intercepts easypy calls and invoke creation or setting of the corresponding AEReport elements/attributes.

class pyats.aereport.aerunner.AERunner(logsdir, logfilename, verbose=False, hostname='127.0.0.1', port=0)

Bases: object

This class receives calls from easypy, and other engines for starting and populating execution contexts (testsuite, testcase, subtest, etc) and their children. It determines the current context, validate the call, and invoke the corresponding API on the targeted element.

The keys of this dictionary are the arguments used for ats.tims.utils.call_importer method. They are: - filename (str): the prefix for the file name to be generated. (It will be appended with .results). If not provided, the default is ‘tims’, so generated file name is tims.results - dns (str): dns of the tims database (unique string) - Usually in form ‘tims/<id>’ e.g. ‘tims/Tvm1p’. If not provided, the default is taken from testsuite.tims.dnsname - tims_user (str): user submitting this job (optional). If not provided, the default is taken from testsuite.initinfo.submitter - config_id (str): TIMS global attribute config_id, maps to Configuration ID, Related Config or logical identifier. - ios_commands_file (str): path and file of ios commands (optional) - folder (str): folder name in the tims database (optional) - kwargs (str): other keyword arguments.

class pyats.aereport.aerunner.ClientNode(host, pid, parent=None)

Bases: object

Each client process is maintained in a ClientNode (in a tree structure). Each clientnode maintains its own ID (host + pid), a pointer to its parent node, and a list of children. In addition, it contains the client context stack, and a status indicator (terminated).

host

Name of the host machine the client is running on

Type

str

pid

Process ID of the client

Type

str

parent

Reference to the parent node

Type

ClientNode

ctx_stack

A container for the contexts executed by the client

Type

list

add_child(child)

Add a child to the current node.

Parameters

child (ClientNode) – The ClientNode to be added as a child of the caller

Returns

Return type

None

Raises

TypeError – Raised when the child is not of type ClientNode

add_ctx(ctx)

Add a context to this client’s ctx_stack. The operation is only executed if the client is not terminated (virtually).

Parameters

ctx (AEReportElement) –

cur_ctx()

Return the top item in the context stack. If the stack is empty, get the top item from the parent node, and so on. Keep bubbling up until reaching a context or None.

Returns

ctx

Return type

AEReportElement or None

pop_ctx()

Remove the top item in the stack and return it. If the stack is empty, return None

Returns

ctx

Return type

AEReportElement or None

set_parent(node)

Set the parent client node.

Parameters

node (ClientNode) – The ClientNode to be used as the parent for the caller

Raises

TypeError – Raised when the child is not of type ClientNode

terminate(_terminate_children=True)

This is a generator method. It calls itself recursively on each child (by default) of the current ClientNode (self) and processes it. Processing is done by emptying its context stack (pop all items) and yielding the client node and the popped context each time. Finally, it sets terminated flag to True. It repeats this (recursively) for every node (under the current one).

Parameters

_terminate_children (bool) – Default = True. A flag to indicate whether child nodes need to be terminated or not

Yields
  • clt (ClientNode) – The client node that contained the popped context in its stack

  • ctx (AEReportElement) – The popped context (testsuite, testscript, etc)

Type

ClientNode

size

The number of nodes in the clients tree

Type

int

num_contexts

The total number of context items in the whole tree

Type

class pyats.aereport.aerunner.OrphanFreeSimpleXMLRPCServer(*args, **kwargs)

service_actions()

Technically, you want the server to exit the same time when the parent’s process has terminated. If the parent process terminates unexpectedly, AEReport server becomes a lingering process and re-parented to the ini(1) process. https://en.wikipedia.org/wiki/Orphan_process

checks whether parent process has been re-parented to init every 10 seconds. when orphan process is detected, log it and sys.exit(0)

class pyats.aereport.aerunner.RequestHandler(request, client_address, server)

client – Client

This module implements AEclient. It contains the direct APi the client can use to connect and to communicate to the xml-rpc server.

class pyats.aereport.client.AEClient(wrapped=None, port=None, servername=None, ppid=None, phost=None)

Bases: object

This is a wrapper for xmlrpc proxy. For python test code that needs to produce AEReport xmls, it should import and use AEClient as the tool for making RPCs to the server. AEClient embeds an xmlrpc proxy, maintains the client identifiers (hostname and pid), and provides them to server with every API invocation. Although python xmlrpc does not support keyword arguments, this class overrides the default __getattr__ and __call__ methods to support keywords arguments, and also to automatically add client identifier to every call.

_serverport

The port that should be used to connect to the server

Type

str

_servername

The hostname of the machine where the server runs

Type

str

xmlrpc

The proxy for making remote procedure calls

Type

xmlrpclib.ServerProxy

_pid

The process ID of this client. This is automatically populated by the init method

Type

str

_hostname

The hostname of the machine where this client runs. This is automatically populated by the init method

Type

str

_ppid

The process ID of the parent of this process. It could, however, be a process on a different physical machine. That’s why this value should be explicitly provided. If not provided, AEClient assumes that it is on the same physical machine, and tries to get it automatically

Type

str

_phostname

The hostname of the machine where the parent of the client runs. It could be a different physical machine. That’s why this value should be explicitly provided. If not provided, AEClient assumes that it is on the same physical machine, and tries to get it automatically

Type

str

Example

>>> # Start the server process (if not already done)
>>> svrpid, svrport, servername = AERunner.start_server(logsdir='/tmp/ttt/',
>>>                                         logfilename='logfile.log')
>>> # Create an AEClient instance
>>> clt = AEClient(port=svrport,servername=servername)
>>> # Connect to the server
>>> clt.connect()
>>> # Make RPCs
>>> clt.start_testsuite(**{'name':'job1',
>>>                        'submitter':'anUser'})
>>> clt.add_ats_packages(packages=[('Csccon', '1.1'), ('aetest', '1.2')])
>>> clt.stop_testsuite()
>>> # Generate your xml reports
>>> clt.generate_xml_reports(path='/tmp/')
>>> # Terminate the server
>>> AERunner.terminate_server()
connect()

Attempt to connect to the server using information received from __init__. It keeps trying to connect 50 times with a 0.5 sec delay in between. If connection succeeds, it registers the client (and its parent) info with the server, and then instantiate the xmlrpc member of this class. If not, it raises a NoConnectionError exception.

Example

>>>  client.connect()
Returns

If no issues with connecting

Return type

None

Raises

NoConnectionError – Raised if the method fails to connect to the server

classmethod create_from_cli()

Parse AEClient attributes from cli (using argparse lib), and return an instance of AEClient. If if the parent client hostname and pid are not provided, it assumes them to be on the same machine as the client, and gets them automatically.

disable_forked()

Disable forking behavior of this class instance. All forked child process will no longer be connected to server.

Multiple calls to this api does not generate exceptions.

enable_forked()

Enable forking behavior of this class instance. All forked child process will automatically reconnect to the parent server

Multiple calls to this api does not generate exceptions.

static forked(instance)

api to be called as soon as the process containing this instance object is forked. This api forces the instance to reconnect to the previous server and re-register the new pid so that it continues functioning
