This class wraps a socket and provides TLS handshaking and data
transfer.
To use this class, create a new instance, passing a connected
socket into the constructor. Then call some handshake function.
If the handshake completes without raising an exception, then a TLS
connection has been negotiated. You can transfer data over this
connection as if it were a socket.
This class provides both synchronous and asynchronous versions of
its key functions. The synchronous versions should be used when
writing single-or multi-threaded code using blocking sockets. The
asynchronous versions should be used when performing asynchronous,
event-based I/O with non-blocking sockets.
Asynchronous I/O is a complicated subject; typically, you should
not use the asynchronous functions directly, but should use some
framework like asyncore or Twisted which TLS Lite integrates with
(see
L{tlslite.integration.TLSAsyncDispatcherMixIn.TLSAsyncDispatcherMixIn} or
L{tlslite.integration.TLSTwistedProtocolWrapper.TLSTwistedProtocolWrapper}).

"""Perform a handshake in the role of server.
This function performs an SSL or TLS handshake. Depending on
the arguments and the behavior of the client, this function can
perform a shared-key, SRP, or certificate-based handshake. It
can also perform a combined SRP and server-certificate
handshake.
Like any handshake function, this can be called on a closed
TLS connection, or on a TLS connection that is already open.
If called on an open connection it performs a re-handshake.
This function does not send a Hello Request message before
performing the handshake, so if re-handshaking is required,
the server must signal the client to begin the re-handshake
through some other means.
If the function completes without raising an exception, the
TLS connection will be open and available for data transfer.
If an exception is raised, the connection will have been
automatically closed (if it was ever open).
@type sharedKeyDB: L{tlslite.SharedKeyDB.SharedKeyDB}
@param sharedKeyDB: A database of shared symmetric keys
associated with usernames. If the client performs a
shared-key handshake, the session's sharedKeyUsername

@type verifierDB: L{tlslite.VerifierDB.VerifierDB}
@param verifierDB: A database of SRP password verifiers
associated with usernames. If the client performs an SRP
handshake, the session's srpUsername attribute will be set.
@type certChain: L{tlslite.X509CertChain.X509CertChain} or

@param certChain: The certificate chain to be used if the
client requests server certificate authentication.

@param privateKey: The private key to be used if the client
requests server certificate authentication.
@type reqCert: bool
@param reqCert: Whether to request client certificate
authentication. This only applies if the client chooses server
certificate authentication; if the client chooses SRP or
shared-key authentication, this will be ignored. If the client
performs a client certificate authentication, the sessions's
clientCertChain attribute will be set.
@type sessionCache: L{tlslite.SessionCache.SessionCache}
@param sessionCache: An in-memory cache of resumable sessions.
The client can resume sessions from this cache. Alternatively,
if the client performs a full handshake, a new session will be
added to the cache.

module: git
author:
- "Ansible Core Team"
- "Michael DeHaan"
version_added: "0.0.1"
short_description: Deploy software (or files) from git checkouts
description:
- Manage I(git) checkouts of repositories to deploy files or software.
options:
repo:
required: true
aliases: [ name ]
description:
- git, SSH, or HTTP protocol address of the git repository.
dest:
required: true
description:
- Absolute path of where the repository should be checked out to.
This parameter is required, unless C(clone) is set to C(no)
This change was made in version 1.8.3. Prior to this version,
the C(dest) parameter was always required.
version:
required: false
default: "HEAD"
description:
- What version of the repository to check out. This can be the
full 40-character I(SHA-1) hash, the literal string C(HEAD), a
branch name, or a tag name.
accept_hostkey:
required: false
default: "no"
choices: [ "yes", "no" ]
version_added: "1.5"
description:
- if C(yes), adds the hostkey for the repo url if not already
added. If ssh_args contains "-o StrictHostKeyChecking=no",
this parameter is ignored.
ssh_opts:
required: false
default: None
version_added: "1.5"
description:
- Creates a wrapper script and exports the path as GIT_SSH
which git then automatically uses to override ssh arguments.
An example value could be "-o StrictHostKeyChecking=no"
key_file:
required: false
default: None
version_added: "1.5"
description:
- Specify an optional private key file to use for the checkout.
reference:
required: false
default: null
version_added: "1.4"
description:
- Reference repository (see "git clone --reference ...")
remote:
required: false
default: "origin"
description:
- Name of the remote.
refspec:
required: false
default: null
version_added: "1.9"
description:
- Add an additional refspec to be fetched.
If version is set to a I(SHA-1) not reachable from any branch
or tag, this option may be necessary to specify the ref containing
the I(SHA-1).
Uses the same syntax as the 'git fetch' command.
An example value could be "refs/meta/config".
force:
required: false
default: "no"
choices: [ "yes", "no" ]
version_added: "0.7"
description:
- If C(yes), any modified files in the working
repository will be discarded. Prior to 0.7, this was always
'yes' and could not be disabled. Prior to 1.9, the default was
`yes`
depth:
required: false
default: null
version_added: "1.2"
description:
- Create a shallow clone with a history truncated to the specified
number or revisions. The minimum possible value is C(1), otherwise
ignored.
clone:
required: false
default: "yes"
choices: [ "yes", "no" ]
version_added: "1.9"
description:
- If C(no), do not clone the repository if it does not exist locally
update:
required: false
default: "yes"
choices: [ "yes", "no" ]
version_added: "1.2"
description:
- If C(no), do not retrieve new revisions from the origin repository
executable:
required: false
default: null
version_added: "1.4"
description:
- Path to git executable to use. If not supplied,
the normal mechanism for resolving binary paths will be used.
bare:
required: false
default: "no"
choices: [ "yes", "no" ]
version_added: "1.4"
description:
- if C(yes), repository will be created as a bare repo, otherwise
it will be a standard repo with a workspace.
recursive:
required: false
default: "yes"
choices: [ "yes", "no" ]
version_added: "1.6"
description:
- if C(no), repository will be cloned without the --recursive
option, skipping sub-modules.
track_submodules:
required: false
default: "no"
choices: ["yes", "no"]
version_added: "1.8"
description:
- if C(yes), submodules will track the latest commit on their
master branch (or other branch specified in .gitmodules). If
C(no), submodules will be kept at the revision specified by the
main project. This is equivalent to specifying the --remote flag
to git submodule update.
verify_commit:
required: false
default: "no"
choices: ["yes", "no"]
version_added: "2.0"
description:
- if C(yes), when cloning or checking out a C(version) verify the
signature of a GPG signed commit. This requires C(git) version>=2.1.0
to be installed. The commit MUST be signed and the public key MUST
be trusted in the GPG trustdb.
requirements:
- git (the command line tool)
notes:
- "If the task seems to be hanging, first verify remote host is in C(known_hosts).
SSH will prompt user to authorize the first contact with a remote host. To avoid this prompt,
one solution is to add the remote host public key in C(/etc/ssh/ssh_known_hosts) before calling
the git module, with the following command: ssh-keyscan -H remote_host.com >> /etc/ssh/ssh_known_hosts."

of very small and simple rows.
A special test here illustrates the difference between fetching the
rows from the raw DBAPI and throwing them away, vs. assembling each
row into a completely basic Python object and appending to a list. The
time spent typically more than doubles. The point is that while
DBAPIs will give you raw rows very fast if they are written in C, the
moment you do anything with those rows, even something trivial,
overhead grows extremely fast in cPython. SQLAlchemy's Core and
lighter-weight ORM options add absolutely minimal overhead, and the
full blown ORM doesn't do terribly either even though mapped objects
provide a huge amount of functionality.

blackrain-audio/supercollider | refs/heads/master | external_libraries/simplejson-2.3.2/__init__.py | 44 | r"""JSON (JavaScript Object Notation) <http://json.org> is a subset of
JavaScript syntax (ECMA-262 3rd edition) used as a lightweight data
interchange format.
:mod:`simplejson` exposes an API familiar to users of the standard library
:mod:`marshal` and :mod:`pickle` modules. It is the externally maintained
version of the :mod:`json` library contained in Python 2.6, but maintains
compatibility with Python 2.4 and Python 2.5 and (currently) has
significant performance advantages, even without using the optional C
extension for speedups.
Encoding basic Python object hierarchies::
>>> import simplejson as json
>>> json.dumps(['foo', {'bar': ('baz', None, 1.0, 2)}])
'["foo", {"bar": ["baz", null, 1.0, 2]}]'
>>> print json.dumps("\"foo\bar")
"\"foo\bar"
>>> print json.dumps(u'\u1234')
"\u1234"
>>> print json.dumps('\\')
"\\"
>>> print json.dumps({"c": 0, "b": 0, "a": 0}, sort_keys=True)
{"a": 0, "b": 0, "c": 0}
>>> from StringIO import StringIO
>>> io = StringIO()
>>> json.dump(['streaming API'], io)
>>> io.getvalue()
'["streaming API"]'
Compact encoding::
>>> import simplejson as json
>>> json.dumps([1,2,3,{'4': 5, '6': 7}], separators=(',',':'))
'[1,2,3,{"4":5,"6":7}]'
Pretty printing::
>>> import simplejson as json
>>> s = json.dumps({'4': 5, '6': 7}, sort_keys=True, indent=' ')
>>> print '\n'.join([l.rstrip() for l in s.splitlines()])
{
"4": 5,
"6": 7
}
Decoding JSON::
>>> import simplejson as json
>>> obj = [u'foo', {u'bar': [u'baz', None, 1.0, 2]}]
>>> json.loads('["foo", {"bar":["baz", null, 1.0, 2]}]') == obj
True
>>> json.loads('"\\"foo\\bar"') == u'"foo\x08ar'
True
>>> from StringIO import StringIO
>>> io = StringIO('["streaming API"]')
>>> json.load(io)[0] == 'streaming API'
True
Specializing JSON object decoding::
>>> import simplejson as json
>>> def as_complex(dct):
... if '__complex__' in dct:
... return complex(dct['real'], dct['imag'])
... return dct
...
>>> json.loads('{"__complex__": true, "real": 1, "imag": 2}',
... object_hook=as_complex)
(1+2j)
>>> from decimal import Decimal
>>> json.loads('1.1', parse_float=Decimal) == Decimal('1.1')
True
Specializing JSON object encoding::
>>> import simplejson as json
>>> def encode_complex(obj):
... if isinstance(obj, complex):
... return [obj.real, obj.imag]
... raise TypeError(repr(o) + " is not JSON serializable")
...
>>> json.dumps(2 + 1j, default=encode_complex)
'[2.0, 1.0]'
>>> json.JSONEncoder(default=encode_complex).encode(2 + 1j)
'[2.0, 1.0]'
>>> ''.join(json.JSONEncoder(default=encode_complex).iterencode(2 + 1j))
'[2.0, 1.0]'
Using simplejson.tool from the shell to validate and pretty-print::
$ echo '{"json":"obj"}' | python -m simplejson.tool
{
"json": "obj"
}
$ echo '{ 1.2:3.4}' | python -m simplejson.tool

"""Variational Inference for the Infinite Gaussian Mixture Model.
DPGMM stands for Dirichlet Process Gaussian Mixture Model, and it
is an infinite mixture model with the Dirichlet Process as a prior
distribution on the number of clusters. In practice the
approximate inference algorithm uses a truncated distribution with
a fixed maximum number of components, but almost always the number
of components actually used depends on the data.
Stick-breaking Representation of a Gaussian mixture model
probability distribution. This class allows for easy and efficient
inference of an approximate posterior distribution over the
parameters of a Gaussian mixture model with a variable number of
components (smaller than the truncation parameter n_components).
Initialization is with normally-distributed means and identity
covariance, for proper convergence.
Read more in the :ref:`User Guide <dpgmm>`.
Parameters
----------
n_components: int, default 1
Number of mixture components.
covariance_type: string, default 'diag'
String describing the type of covariance parameters to
use. Must be one of 'spherical', 'tied', 'diag', 'full'.
alpha: float, default 1
Real number representing the concentration parameter of
the dirichlet process. Intuitively, the Dirichlet Process
is as likely to start a new cluster for a point as it is
to add that point to a cluster with alpha elements. A
higher alpha means more clusters, as the expected number
of clusters is ``alpha*log(N)``.
tol : float, default 1e-3
Convergence threshold.
n_iter : int, default 10
Maximum number of iterations to perform before convergence.
params : string, default 'wmc'
Controls which parameters are updated in the training
process. Can contain any combination of 'w' for weights,
'm' for means, and 'c' for covars.
init_params : string, default 'wmc'
Controls which parameters are updated in the initialization
process. Can contain any combination of 'w' for weights,
'm' for means, and 'c' for covars. Defaults to 'wmc'.
verbose : int, default 0
Controls output verbosity.
Attributes
----------
covariance_type : string
String describing the type of covariance parameters used by
the DP-GMM. Must be one of 'spherical', 'tied', 'diag', 'full'.
n_components : int
Number of mixture components.
weights_ : array, shape (`n_components`,)
Mixing weights for each mixture component.
means_ : array, shape (`n_components`, `n_features`)
Mean parameters for each mixture component.
precs_ : array
Precision (inverse covariance) parameters for each mixture
component. The shape depends on `covariance_type`::
(`n_components`, 'n_features') if 'spherical',
(`n_features`, `n_features`) if 'tied',
(`n_components`, `n_features`) if 'diag',
(`n_components`, `n_features`, `n_features`) if 'full'
converged_ : bool
True when convergence was reached in fit(), False otherwise.

GMM : Finite Gaussian mixture model fit with EM
VBGMM : Finite Gaussian mixture model fit with a variational
algorithm, better for situations where there might be too little
data to get a good estimate of the covariance matrix.

"""Variational Inference for the Gaussian Mixture Model
Variational inference for a Gaussian mixture model probability
distribution. This class allows for easy and efficient inference
of an approximate posterior distribution over the parameters of a
Gaussian mixture model with a fixed number of components.
Initialization is with normally-distributed means and identity
covariance, for proper convergence.
Read more in the :ref:`User Guide <vbgmm>`.
Parameters
----------
n_components: int, default 1
Number of mixture components.
covariance_type: string, default 'diag'
String describing the type of covariance parameters to
use. Must be one of 'spherical', 'tied', 'diag', 'full'.
alpha: float, default 1
Real number representing the concentration parameter of
the dirichlet distribution. Intuitively, the higher the
value of alpha the more likely the variational mixture of
Gaussians model will use all components it can.
tol : float, default 1e-3
Convergence threshold.
n_iter : int, default 10
Maximum number of iterations to perform before convergence.
params : string, default 'wmc'
Controls which parameters are updated in the training
process. Can contain any combination of 'w' for weights,
'm' for means, and 'c' for covars.
init_params : string, default 'wmc'
Controls which parameters are updated in the initialization
process. Can contain any combination of 'w' for weights,
'm' for means, and 'c' for covars. Defaults to 'wmc'.
verbose : int, default 0
Controls output verbosity.
Attributes
----------
covariance_type : string
String describing the type of covariance parameters used by
the DP-GMM. Must be one of 'spherical', 'tied', 'diag', 'full'.
n_features : int
Dimensionality of the Gaussians.
n_components : int (read-only)
Number of mixture components.
weights_ : array, shape (`n_components`,)
Mixing weights for each mixture component.
means_ : array, shape (`n_components`, `n_features`)
Mean parameters for each mixture component.
precs_ : array
Precision (inverse covariance) parameters for each mixture
component. The shape depends on `covariance_type`::
(`n_components`, 'n_features') if 'spherical',
(`n_features`, `n_features`) if 'tied',
(`n_components`, `n_features`) if 'diag',
(`n_components`, `n_features`, `n_features`) if 'full'
converged_ : bool
True when convergence was reached in fit(), False
otherwise.
