# 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: replace
author: "Evan Kaufman (@EvanK)"
extends_documentation_fragment:
- files
- validate
short_description: Replace all instances of a particular string in a
file using a back-referenced regular expression.
description:
- This module will replace all instances of a pattern within a file.
- It is up to the user to maintain idempotence by ensuring that the
same pattern would never match any replacements made.
version_added: "1.6"
options:
path:
required: true
aliases: [ dest, destfile, name ]
description:
- The file to modify.
- Before 2.3 this option was only usable as I(dest), I(destfile) and I(name).
regexp:
required: true
description:
- The regular expression to look for in the contents of the file.
Uses Python regular expressions; see
U(http://docs.python.org/2/library/re.html).
Uses multiline mode, which means C(^) and C($) match the beginning
and end respectively of I(each line) of the file.
replace:
required: false
description:
- The string to replace regexp matches. May contain backreferences
that will get expanded with the regexp capture groups if the regexp
matches. If not set, matches are removed entirely.
backup:
required: false
default: "no"
choices: [ "yes", "no" ]
description:
- Create a backup file including the timestamp information so you can
get the original file back if you somehow clobbered it incorrectly.
others:
description:
- All arguments accepted by the M(file) module also work here.
required: false
follow:
required: false
default: "no"
choices: [ "yes", "no" ]
version_added: "1.9"
description:
- 'This flag indicates that filesystem links, if they exist, should be followed.'
notes:
- As of Ansible 2.3, the I(dest) option has been changed to I(path) as default, but I(dest) still works as well.
"""
EXAMPLES = r"""
# Before 2.3, option 'dest', 'destfile' or 'name' was used instead of 'path'
- replace:
path: /etc/hosts
regexp: '(\s+)old\.host\.name(\s+.*)?$'
replace: '\1new.host.name\2'
backup: yes
- replace:
path: /home/jdoe/.ssh/known_hosts
regexp: '^old\.host\.name[^\n]*\n'
owner: jdoe
group: jdoe
mode: 0644
- replace:
path: /etc/apache/ports
regexp: '^(NameVirtualHost|Listen)\s+80\s*$'
replace: '\1 127.0.0.1:8080'

short_description: Manage docker configs.
version_added: "2.8"
description:
- Create and remove Docker configs in a Swarm environment. Similar to C(docker config create) and C(docker config rm).
- Adds to the metadata of new configs 'ansible_key', an encrypted hash representation of the data, which is then used
in future runs to test if a config has changed. If 'ansible_key' is not present, then a config will not be updated
unless the I(force) option is set.
- Updates to configs are performed by removing the config and creating it again.
options:
data:
description:
- The value of the config. Required when state is C(present).
type: str
data_is_b64:
description:
- If set to C(true), the data is assumed to be Base64 encoded and will be
decoded before being used.
- To use binary I(data), it is better to keep it Base64 encoded and let it
be decoded by this option.
type: bool
default: no
labels:
description:
- "A map of key:value meta data, where both the I(key) and I(value) are expected to be a string."
- If new meta data is provided, or existing meta data is modified, the config will be updated by removing it and creating it again.
type: dict
force:
description:
- Use with state C(present) to always remove and recreate an existing config.
- If C(true), an existing config will be replaced, even if it has not been changed.

Grid Layout
===========
.. only:: html
.. image:: images/gridlayout.gif
:align: right
.. only:: latex
.. image:: images/gridlayout.png
:align: right
.. versionadded:: 1.0.4
The :class:`GridLayout` arranges children in a matrix. It takes the available
space and divides it into columns and rows, then adds widgets to the resulting
"cells".
.. versionchanged:: 1.0.7
The implementation has changed to use the widget size_hint for calculating
column/row sizes. `uniform_width` and `uniform_height` have been removed
and other properties have added to give you more control.
Background
----------
Unlike many other toolkits, you cannot explicitly place a widget in a specific
column/row. Each child is automatically assigned a position determined by the
layout configuration and the child's index in the children list.
A GridLayout must always have at least one input constraint:
:attr:`GridLayout.cols` or :attr:`GridLayout.rows`. If you do not specify cols
or rows, the Layout will throw an exception.
Column Width and Row Height
---------------------------
The column width/row height are determined in 3 steps:
- The initial size is given by the :attr:`col_default_width` and
:attr:`row_default_height` properties. To customize the size of a single
column or row, use :attr:`cols_minimum` or :attr:`rows_minimum`.
- The `size_hint_x`/`size_hint_y` of the children are taken into account.
If no widgets have a size hint, the maximum size is used for all
children.
- You can force the default size by setting the :attr:`col_force_default`
or :attr:`row_force_default` property. This will force the layout to
ignore the `width` and `size_hint` properties of children and use the
default size.
Using a GridLayout
------------------
In the example below, all widgets will have an equal size. By default, the
`size_hint` is (1, 1), so a Widget will take the full size of the parent::
layout = GridLayout(cols=2)
layout.add_widget(Button(text='Hello 1'))
layout.add_widget(Button(text='World 1'))
layout.add_widget(Button(text='Hello 2'))
layout.add_widget(Button(text='World 2'))
.. image:: images/gridlayout_1.jpg
Now, let's fix the size of Hello buttons to 100px instead of using
size_hint_x=1::
layout = GridLayout(cols=2)
layout.add_widget(Button(text='Hello 1', size_hint_x=None, width=100))
layout.add_widget(Button(text='World 1'))
layout.add_widget(Button(text='Hello 2', size_hint_x=None, width=100))
layout.add_widget(Button(text='World 2'))
.. image:: images/gridlayout_2.jpg
Next, let's fix the row height to a specific size::
layout = GridLayout(cols=2, row_force_default=True, row_default_height=40)
layout.add_widget(Button(text='Hello 1', size_hint_x=None, width=100))
layout.add_widget(Button(text='World 1'))
layout.add_widget(Button(text='Hello 2', size_hint_x=None, width=100))
layout.add_widget(Button(text='World 2'))
.. image:: images/gridlayout_3.jpg

The procurement group class is used to group products together
when computing procurements. (tasks, physical products, ...)
The goal is that when you have one sale order of several products
and the products are pulled from the same or several location(s), to keep
having the moves grouped into pickings that represent the sale order.
Used in: sales order (to group delivery order lines like the so), pull/push
rules (to pack like the delivery order), on orderpoints (e.g. for wave picking
all the similar products together).
Grouping is made only if the source and the destination is the same.
Suppose you have 4 lines on a picking from Output where 2 lines will need
to come from Input (crossdock) and 2 lines coming from Stock -> Output As
the four procurement orders will have the same group ids from the SO, the
move from input will have a stock.picking with 2 grouped lines and the move
from stock will have 2 grouped lines also.
The name is usually the name of the original document (sale order) or a
sequence computed if created manually.

application (http://habitlist.com/) into Day One Journal
(http://dayoneapp.com/) entries.
To use this module you must first do a manual export of your data from Habit
list. This can be done by the following:
- Open Habit List iPhone app
- Click the 'gear' icon for settings at the bottom of the main 'Today' view
- Choose the 'Export Data' option
- E-mail the data to yourself
- Copy and paste the e-mail contents into a file of your choosing
- Remove the 'sent from iPhone' line at the end of your e-mail. This
will cause the script to NOT process the JSON data.
- DO NOT REMOVE THE LAST TWO EMPTY LINES OF THE E-MAIL. WE CURRENTLY
HAVE A BUG THAT EXPECTS THESE LINES.
- You can choose to optionally remove the first few lines of the e-mail
that are not JSON data, everything up to the first '[' character.
- Again, this is optional because this module will attempt to ignore
any non-JSON data at the START of a file.
At this point, you are ready to do the actual conversion from JSON to Day One
entires. So, you should check all the 'settings' in this module for things you
would like to change:
- HEADER_FOR_DAY_ONE_ENTRIES
- DAYONE_ENTRIES
- ENTRY_TEMPLATE
- TIMEZONE
- Make sure to choose the timezone of your iPhone because the Habit
List app stores all timezones in UTC and you'll want to convert this
to the timezone your iPhone used at the time you completed the habit.
This will ensure your Day One entries match the time you completed
the task and also prevent a habit from showing up more than once per
day which can happen with UTC time if you complete a habit late in
one day and early in the next, etc.
- You can find a list of available timezone strings here:
- http://en.wikipedia.org/wiki/List_of_tz_database_time_zones
Next, you can run this module with your exported JSON data as an argument like
so:
- python services/habit_list.py -f habit_list_data.json -t
Also, it's encouraged to run this with the '-t' option first so that all your
Day One entires will be created in a local directory called 'test.' This will
allow you to inspect the conversion. You can manually copy a few select
entries into your Day One 'entries/' folder to ensure you approve of the
formatting and can easily make any formatting adjustments. Then, you can run
this module again without the '-t' to fully import Habit List entries into Day
One.

"""Execute the decorated test with all Keras model types.
This decorator is intended to be applied either to individual test methods in
a `keras_parameterized.TestCase` class, or directly to a test class that
extends it. Doing so will cause the contents of the individual test
method (or all test methods in the class) to be executed multiple times - once
for each Keras model type.
The Keras model types are: ['functional', 'subclass', 'sequential']
Note: if stacking this decorator with absl.testing's parameterized decorators,
those should be at the bottom of the stack.
Various methods in `testing_utils` to get models will auto-generate a model
of the currently active Keras model type. This allows unittests to confirm
the equivalence between different Keras models.
For example, consider the following unittest:
```python
class MyTests(testing_utils.KerasTestCase):
@testing_utils.run_with_all_model_types(
exclude_models = ['sequential'])
def test_foo(self):
model = testing_utils.get_small_mlp(1, 4, input_dim=3)
optimizer = RMSPropOptimizer(learning_rate=0.001)
loss = 'mse'
metrics = ['mae']
model.compile(optimizer, loss, metrics=metrics)
inputs = np.zeros((10, 3))
targets = np.zeros((10, 4))
dataset = dataset_ops.Dataset.from_tensor_slices((inputs, targets))
dataset = dataset.repeat(100)
dataset = dataset.batch(10)
model.fit(dataset, epochs=1, steps_per_epoch=2, verbose=1)
if __name__ == "__main__":
tf.test.main()
```
This test tries building a small mlp as both a functional model and as a
subclass model.
We can also annotate the whole class if we want this to apply to all tests in
the class:
```python
@testing_utils.run_with_all_model_types(exclude_models = ['sequential'])
class MyTests(testing_utils.KerasTestCase):
def test_foo(self):
model = testing_utils.get_small_mlp(1, 4, input_dim=3)
optimizer = RMSPropOptimizer(learning_rate=0.001)
loss = 'mse'
metrics = ['mae']
model.compile(optimizer, loss, metrics=metrics)
inputs = np.zeros((10, 3))
targets = np.zeros((10, 4))
dataset = dataset_ops.Dataset.from_tensor_slices((inputs, targets))
dataset = dataset.repeat(100)
dataset = dataset.batch(10)
model.fit(dataset, epochs=1, steps_per_epoch=2, verbose=1)
if __name__ == "__main__":
tf.test.main()
```
Args:
test_or_class: test method or class to be annotated. If None,
this method returns a decorator that can be applied to a test method or
test class. If it is not None this returns the decorator applied to the
test or class.
exclude_models: A collection of Keras model types to not run.
(May also be a single model type not wrapped in a collection).
Defaults to None.

Returns a decorator that will run the decorated test method multiple times:
once for each desired Keras model type.

"""Execute the decorated test with all keras execution modes.
This decorator is intended to be applied either to individual test methods in
a `keras_parameterized.TestCase` class, or directly to a test class that
extends it. Doing so will cause the contents of the individual test
method (or all test methods in the class) to be executed multiple times -
once executing in legacy graph mode, once running eagerly and with
`should_run_eagerly` returning True, and once running eagerly with
`should_run_eagerly` returning False.
If Tensorflow v2 behavior is enabled, legacy graph mode will be skipped, and
the test will only run twice.
Note: if stacking this decorator with absl.testing's parameterized decorators,
those should be at the bottom of the stack.
For example, consider the following unittest:
```python
class MyTests(testing_utils.KerasTestCase):
@testing_utils.run_all_keras_modes
def test_foo(self):
model = testing_utils.get_small_functional_mlp(1, 4, input_dim=3)
optimizer = RMSPropOptimizer(learning_rate=0.001)
loss = 'mse'
metrics = ['mae']
model.compile(optimizer, loss, metrics=metrics,
run_eagerly=testing_utils.should_run_eagerly())
inputs = np.zeros((10, 3))
targets = np.zeros((10, 4))
dataset = dataset_ops.Dataset.from_tensor_slices((inputs, targets))
dataset = dataset.repeat(100)
dataset = dataset.batch(10)
model.fit(dataset, epochs=1, steps_per_epoch=2, verbose=1)
if __name__ == "__main__":
tf.test.main()
```
This test will try compiling & fitting the small functional mlp using all
three Keras execution modes.
Args:
test_or_class: test method or class to be annotated. If None,
this method returns a decorator that can be applied to a test method or
test class. If it is not None this returns the decorator applied to the
test or class.
config: An optional config_pb2.ConfigProto to use to configure the
session when executing graphs.
always_skip_v1: If True, does not try running the legacy graph mode even
when Tensorflow v2 behavior is not enabled.
Returns:
Returns a decorator that will run the decorated test method multiple times.
Raises:
ImportError: If abseil parameterized is not installed or not included as
a target dependency.

Codec modules must have names corresponding to normalized encoding

A state machine to manage data sending process, acts very simple:
1) when new local data is created it tries to send it to the correct supplier
2) wait while ``p2p.io_throttle`` is doing some data transmission to remote suppliers
3) calls ``p2p.backup_matrix.ScanBlocksToSend()`` to get a list of pieces needs to be send
4) this machine is restarted every minute to check if some more data needs to be send
5) also can be restarted at any time when it is needed
EVENTS:
* :red:`block-acked`
* :red:`block-failed`
* :red:`init`
* :red:`new-data`
* :red:`restart`
* :red:`scan-done`
* :red:`timer-1min`
* :red:`timer-1sec`
