Recursively Nested Bootstrap
|
||
|
|
----------------------------
|
||
|
|
|
||
|
|
This demonstrates the library's ability to use slave contexts to recursively
|
||
|
|
proxy connections to additional slave contexts, with a uniform API to any
|
||
|
|
slave, and all features (function calls, import forwarding, stdio forwarding,
|
||
|
|
log forwarding) functioning transparently.
|
||
|
|
|
||
|
|
This example uses a chain of local contexts for clarity, however SSH and sudo
|
||
|
|
contexts work identically.
|
||
|
|
|
||
|
|
nested.py:
|
||
|
|
|
||
|
|
.. code-block:: python
|
||
|
|
|
||
|
|
import os
|
||
|
|
import mitogen.utils
|
||
|
|
|
||
|
|
@mitogen.utils.run_with_router
|
||
|
|
def main(router):
|
||
|
|
mitogen.utils.log_to_file()
|
||
|
|
|
||
|
|
context = None
|
||
|
|
for x in range(1, 11):
|
||
|
|
print 'Connect local%d via %s' % (x, context)
|
||
|
|
context = router.local(via=context, name='local%d' % x)
|
||
|
|
|
||
|
|
context.call(os.system, 'pstree -s python -s mitogen')
|
||
|
|
|
||
|
|
|
||
|
|
Output:
|
||
|
|
|
||
|
|
.. code-block:: shell
|
||
|
|
|
||
|
|
$ python nested.py
|
||
|
|
Connect local1 via None
|
||
|
|
Connect local2 via Context(1, 'local1')
|
||
|
|
Connect local3 via Context(2, 'local2')
|
||
|
|
Connect local4 via Context(3, 'local3')
|
||
|
|
Connect local5 via Context(4, 'local4')
|
||
|
|
Connect local6 via Context(5, 'local5')
|
||
|
|
Connect local7 via Context(6, 'local6')
|
||
|
|
Connect local8 via Context(7, 'local7')
|
||
|
|
Connect local9 via Context(8, 'local8')
|
||
|
|
Connect local10 via Context(9, 'local9')
