"""Read osc configuration and store it in a dictionary
This module reads and parses ~/.oscrc. The resulting configuration is stored
for later usage in a dictionary named 'config'.
The .oscrc is kept mode 0600, so that it is not publically readable.
This gives no real security for storing passwords.
If in doubt, use your favourite keyring.
Password is stored on ~/.oscrc as bz2 compressed and base64 encoded, so that is fairly
large and not to be recognized or remembered easily by an occasional spectator.
If information is missing, it asks the user questions.
After reading the config, urllib2 is initialized.
The configuration dictionary could look like this:
{'apisrv': 'https://api.opensuse.org/',

The Dirichlet function is defined as::

where `n` is a positive integer.
Parameters
----------
x : array_like
Input data
n : int
Integer defining the periodicity.
Returns
-------
diric : ndarray
Examples
--------
>>> from scipy import special
>>> import matplotlib.pyplot as plt
>>> x = np.linspace(-8*np.pi, 8*np.pi, num=201)
>>> plt.figure(figsize=(8, 8));
>>> for idx, n in enumerate([2, 3, 4, 9]):
... plt.subplot(2, 2, idx+1)
... plt.plot(x, special.diric(x, n))
... plt.title('diric, n={}'.format(n))
>>> plt.show()
The following example demonstrates that `diric` gives the magnitudes
(modulo the sign and scaling) of the Fourier coefficients of a
rectangular pulse.
Suppress output of values that are effectively 0:
>>> np.set_printoptions(suppress=True)
Create a signal `x` of length `m` with `k` ones:
>>> m = 8
>>> k = 3
>>> x = np.zeros(m)
>>> x[:k] = 1
Use the FFT to compute the Fourier transform of `x`, and
inspect the magnitudes of the coefficients:
>>> np.abs(np.fft.fft(x))
array([ 3. , 2.41421356, 1. , 0.41421356, 1. ,
0.41421356, 1. , 2.41421356])
Now find the same values (up to sign) using `diric`. We multiply
by `k` to account for the different scaling conventions of
`numpy.fft.fft` and `diric`:
>>> theta = np.linspace(0, 2*np.pi, m, endpoint=False)
>>> k * special.diric(theta, k)
array([ 3. , 2.41421356, 1. , -0.41421356, -1. ,
-0.41421356, 1. , 2.41421356])

By default, i.e. for ``type=3``, phase conventions are chosen according

factor with respect to Ferrer's function of the first kind
(cf. `lpmn`).
For ``type=2`` a cut at ``|x| > 1`` is chosen. Approaching the real values
on the interval (-1, 1) in the complex plane yields Ferrer's function
of the first kind.

Parameters
----------
n : int or array_like
Calculate ``n!!``. Arrays are only supported with `exact` set

answer exactly using integer arithmetic.
Returns
-------

Double factorial of `n`, as an int or a float depending on
`exact`.
Examples

Riemann or Hurwitz zeta function.
Parameters
----------
x : array_like of float

q : array_like of float, optional
Input data, must be real. Defaults to Riemann zeta.
out : ndarray, optional
Output array for the computed values.
Returns
-------
out : array_like

# This is so much trickier than it sounds, it's not even funny.
# According to RFC 3023 ('XML Media Types'), if the HTTP Content-Type
# is application/xml, application/*+xml,
# application/xml-external-parsed-entity, or application/xml-dtd,
# the encoding given in the charset parameter of the HTTP Content-Type
# takes precedence over the encoding given in the XML prefix within the
# document, and defaults to 'utf-8' if neither are specified. But, if
# the HTTP Content-Type is text/xml, text/*+xml, or
# text/xml-external-parsed-entity, the encoding given in the XML prefix
# within the document is ALWAYS IGNORED and only the encoding given in
# the charset parameter of the HTTP Content-Type header should be
# respected, and it defaults to 'us-ascii' if not specified.
# Furthermore, discussion on the atom-syntax mailing list with the
# author of RFC 3023 leads me to the conclusion that any document
# served with a Content-Type of text/* and no charset parameter
# must be treated as us-ascii. (We now do this.) And also that it
# must always be flagged as non-well-formed. (We now do this too.)
# If Content-Type is unspecified (input was local file or non-HTTP source)
# or unrecognized (server just got it totally wrong), then go by the
# encoding given in the XML prefix of the document and default to
# 'iso-8859-1' as per the HTTP specification (RFC 2616).
# Then, assuming we didn't find a character encoding in the HTTP headers
# (and the HTTP Content-type allowed us to look in the body), we need
# to sniff the first few bytes of the XML data and try to determine
# whether the encoding is ASCII-compatible. Section F of the XML
# specification shows the way here:
# http://www.w3.org/TR/REC-xml/#sec-guessing-no-ext-info
# If the sniffed encoding is not ASCII-compatible, we need to make it
# ASCII compatible so that we can sniff further into the XML declaration
# to find the encoding attribute, which will tell us the true encoding.
# Of course, none of this guarantees that we will be able to parse the
# feed in the declared character encoding (assuming it was declared
# correctly, which many are not). iconv_codec can help a lot;
# you should definitely install it if you can.

module: x509_crl
version_added: "2.10"
short_description: Generate Certificate Revocation Lists (CRLs)
description:
- This module allows one to (re)generate or update Certificate Revocation Lists (CRLs).
- Certificates on the revocation list can be either specified via serial number and (optionally) their issuer,
or as a path to a certificate file in PEM format.
requirements:
- cryptography >= 1.2
author:
- Felix Fontein (@felixfontein)
options:
state:
description:
- Whether the CRL file should exist or not, taking action if the state is different from what is stated.
type: str
default: present
choices: [ absent, present ]
mode:
description:
- Defines how to process entries of existing CRLs.
- If set to C(generate), makes sure that the CRL has the exact set of revoked certificates
as specified in I(revoked_certificates).
- If set to C(update), makes sure that the CRL contains the revoked certificates from
I(revoked_certificates), but can also contain other revoked certificates. If the CRL file
already exists, all entries from the existing CRL will also be included in the new CRL.
When using C(update), you might be interested in setting I(ignore_timestamps) to C(yes).
type: str
default: generate
choices: [ generate, update ]
force:
description:
- Should the CRL be forced to be regenerated.
type: bool
default: no
backup:
description:
- Create a backup file including a timestamp so you can get the original
CRL back if you overwrote it with a new one by accident.
type: bool
default: no
path:
description:
- Remote absolute path where the generated CRL file should be created or is already located.
type: path
required: yes
privatekey_path:
description:
- Path to the CA's private key to use when signing the CRL.
- Either I(privatekey_path) or I(privatekey_content) must be specified if I(state) is C(present), but not both.
type: path
privatekey_content:
description:
- The content of the CA's private key to use when signing the CRL.
- Either I(privatekey_path) or I(privatekey_content) must be specified if I(state) is C(present), but not both.
type: str
privatekey_passphrase:
description:
- The passphrase for the I(privatekey_path).
- This is required if the private key is password protected.
type: str
issuer:
description:
- Key/value pairs that will be present in the issuer name field of the CRL.
- If you need to specify more than one value with the same key, use a list as value.
- Required if I(state) is C(present).
type: dict
last_update:
description:
- The point in time from which this CRL can be trusted.
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent, except when
I(ignore_timestamps) is set to C(yes).
type: str
default: "+0s"
next_update:
description:
- "The absolute latest point in time by which this I(issuer) is expected to have issued
another CRL. Many clients will treat a CRL as expired once I(next_update) occurs."
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent, except when
I(ignore_timestamps) is set to C(yes).
- Required if I(state) is C(present).
type: str
digest:
description:
- Digest algorithm to be used when signing the CRL.
type: str
default: sha256
revoked_certificates:
description:
- List of certificates to be revoked.
- Required if I(state) is C(present).
type: list
elements: dict
suboptions:
path:
description:
- Path to a certificate in PEM format.
- The serial number and issuer will be extracted from the certificate.
- Mutually exclusive with I(content) and I(serial_number). One of these three options
must be specified.
type: path
content:
description:
- Content of a certificate in PEM format.
- The serial number and issuer will be extracted from the certificate.
- Mutually exclusive with I(path) and I(serial_number). One of these three options
must be specified.
type: str
serial_number:
description:
- Serial number of the certificate.
- Mutually exclusive with I(path) and I(content). One of these three options must
be specified.
type: int
revocation_date:
description:
- The point in time the certificate was revoked.
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent, except when
I(ignore_timestamps) is set to C(yes).
type: str
default: "+0s"
issuer:
description:
- The certificate's issuer.
- "Example: C(DNS:ca.example.org)"
type: list
elements: str
issuer_critical:
description:
- Whether the certificate issuer extension should be critical.
type: bool
default: no
reason:
description:
- The value for the revocation reason extension.
type: str
choices:
- unspecified
- key_compromise
- ca_compromise
- affiliation_changed
- superseded
- cessation_of_operation
- certificate_hold
- privilege_withdrawn
- aa_compromise
- remove_from_crl
reason_critical:
description:
- Whether the revocation reason extension should be critical.
type: bool
default: no
invalidity_date:
description:
- The point in time it was known/suspected that the private key was compromised
or that the certificate otherwise became invalid.
- Time can be specified either as relative time or as absolute timestamp.
- Time will always be interpreted as UTC.
- Valid format is C([+-]timespec | ASN.1 TIME) where timespec can be an integer
+ C([w | d | h | m | s]) (e.g. C(+32w1d2h).
- Note that if using relative time this module is NOT idempotent. This will NOT
change when I(ignore_timestamps) is set to C(yes).
type: str
invalidity_date_critical:
description:
- Whether the invalidity date extension should be critical.
type: bool
default: no
ignore_timestamps:
description:
- Whether the timestamps I(last_update), I(next_update) and I(revocation_date) (in
I(revoked_certificates)) should be ignored for idempotency checks. The timestamp
I(invalidity_date) in I(revoked_certificates) will never be ignored.
- Use this in combination with relative timestamps for these values to get idempotency.
type: bool
default: no
return_content:
description:
- If set to C(yes), will return the (current or generated) CRL's content as I(crl).
type: bool
default: no
extends_documentation_fragment:
- files
notes:
- All ASN.1 TIME values should be specified following the YYYYMMDDHHMMSSZ pattern.
- Date specified should be UTC. Minutes and seconds are mandatory.

"""Finds the best pure subset of observations to compute MCD from it.
The purpose of this function is to find the best sets of n_support

matrix determinant. Equivalently, it removes n_samples-n_support
observations to construct what we call a pure data set (i.e. not
containing outliers). The list of the observations of the pure
data set is referred to as the `support`.
Starting from a random support, the pure data set is found by the
c_step procedure introduced by Rousseeuw and Van Driessen in
[RV]_.
Parameters
----------
X : array-like of shape (n_samples, n_features)
Data (sub)set in which we look for the n_support purest observations.

This parameter must be in the range `[(n + p + 1)/2] < n_support < n`.
n_trials : int or tuple of shape (2,)
Number of different initial sets of observations from which to

integer.

list of initial estimates that will be used to iteratively run
c_step procedures. In this case:

is the list of `n_trials` initial location estimates
- n_trials[1]: array-like, shape (n_trials, n_features, n_features)
is the list of `n_trials` initial covariances estimates
select : int, default=1
Number of best candidates results to return. This parameter must be
a strictly positive integer.
n_iter : int, default=30
Maximum number of iterations for the c_step procedure.
(2 is enough to be close to the final solution. "Never" exceeds 20).
This parameter must be a strictly positive integer.
verbose : bool, default=False
Control the output verbosity.
cov_computation_method : callable, \
default=:func:`sklearn.covariance.empirical_covariance`
The function which will be used to compute the covariance.
Must return an array of shape (n_features, n_features).
random_state : int, RandomState instance or None, default=None

Notes
-----
The FastMCD algorithm has been introduced by Rousseuw and Van Driessen
in "A Fast Algorithm for the Minimum Covariance Determinant Estimator,
1999, American Statistical Association and the American Society
for Quality, TECHNOMETRICS".
The principle is to compute robust estimates and random subsets before
pooling them into a larger subsets, and finally into the full data set.
Depending on the size of the initial sample, we have one, two or three
such computation levels.
Note that only raw estimates are returned. If one is interested in
the correction and reweighting steps described in [RouseeuwVan]_,
see the MinCovDet object.

"""Minimum Covariance Determinant (MCD): robust estimator of covariance.
The Minimum Covariance Determinant covariance estimator is to be applied
on Gaussian-distributed data, but could still be relevant on data
drawn from a unimodal, symmetric distribution. It is not meant to be used
with multi-modal data (the algorithm used to fit a MinCovDet object is
likely to fail in such a case).
One should consider projection pursuit methods to deal with multi-modal
datasets.
Read more in the :ref:`User Guide <robust_covariance>`.
Parameters
----------
store_precision : bool, default=True
Specify if the estimated precision is stored.
assume_centered : bool, default=False
If True, the support of the robust location and the covariance
estimates is computed, and a covariance estimate is recomputed from
it, without centering the data.
Useful to work with data whose mean is significantly equal to
zero but is not exactly zero.
If False, the robust location and covariance are directly computed
with the FastMCD algorithm without additional treatment.
support_fraction : float, default=None
The proportion of points to be included in the support of the raw
MCD estimate. Default is None, which implies that the minimum
value of support_fraction will be used within the algorithm:
`(n_sample + n_features + 1) / 2`. The parameter must be in the range
(0, 1).
random_state : int, RandomState instance or None, default=None
Determines the pseudo random number generator for shuffling the data.
Pass an int for reproducible results across multiple function calls.
See :term:`Glossary <random_state>`.
Attributes
----------
raw_location_ : ndarray of shape (n_features,)
The raw robust estimated location before correction and re-weighting.
raw_covariance_ : ndarray of shape (n_features, n_features)
The raw robust estimated covariance before correction and re-weighting.
raw_support_ : ndarray of shape (n_samples,)
A mask of the observations that have been used to compute
the raw robust estimates of location and shape, before correction
and re-weighting.
location_ : ndarray of shape (n_features,)
Estimated robust location.
covariance_ : ndarray of shape (n_features, n_features)
Estimated robust covariance matrix.
precision_ : ndarray of shape (n_features, n_features)
Estimated pseudo inverse matrix.
(stored only if store_precision is True)
support_ : ndarray of shape (n_samples,)
A mask of the observations that have been used to compute
the robust estimates of location and shape.
dist_ : ndarray of shape (n_samples,)
Mahalanobis distances of the training set (on which :meth:`fit` is
called) observations.
n_features_in_ : int
Number of features seen during :term:`fit`.
.. versionadded:: 0.24
feature_names_in_ : ndarray of shape (`n_features_in_`,)
Names of features seen during :term:`fit`. Defined only when `X`
has feature names that are all strings.
.. versionadded:: 1.0

"""A simple wrapper for Django templates.
The main purpose of this module is to hide all of the package import pain
you normally have to go through to get Django to work. We expose the Django
Template and Context classes from this module, handling the import nonsense
on behalf of clients.
Typical usage:
from google.appengine.ext.webapp import template
print template.render('templates/index.html', {'foo': 'bar'})
Django uses a global setting for the directory in which it looks for templates.
This is not natural in the context of the webapp module, so our load method
takes in a complete template path, and we set these settings on the fly
automatically. Because we have to set and use a global setting on every
method call, this module is not thread safe, though that is not an issue
for applications.

We will never return a stale document as

Since we are private we get to ignore both 'public' and
