#
"""\
=========================
Abstract SMTP Mailer Core
=========================
This component effectively forms the skeleton of an SMTP server. It expects
an SMTP client to connect and send various SMTP requests to it. This basic
SMTP Mailer Core however, does not actually do anything in response to any
of the SMTP commands it expects.
Each SMTP command is actually given a dummy callback which more customised
SMTP protocol handlers are expected to override. Beyond this, this component
is expected to be used as a protocol handler for ServerCore.
Fundamentally, this component handles the command/response structure of SMTP
fairly directly, but expects the brains of the protocol to be implemented by
a more intelligent subclass.
Example Usage
-------------
Whilst this will work to a minimal extent::
ServerCore(protocol=MailHandler, port=1025)
This will not actually form a very interesting SMTP, nor SMTP compliant,
server since whilst it will tell you commands it doesn't understand, it will
not do anything interesting.
You are as noted expected to subclass MailHandler. For a better example
of how to subclass MailHandler you are suggested to look at
Kamaelia.Apps.ConcreteMailHandler.ConcreteMailHandler
Note
----
This component is not complete - you are expected to subclass it to finish
it off as you need. Specifically it does not implement the following:
- It does not enforce "this command followed by that command"
- It does not actually do anything with any DATA a client sends you
- It neither performs local mail delivery nor proxying - you'd need to implement this yourself.
How does it work?
-----------------
The component is expected to be connected to a client TCP connection by
ServerCore, such that messages from the network arrive on inbox "inbox", and
outgoing messages get sent to outbox "outbox"
The component will terminate if any of these is true:
- The client breaks the connection
- One of the methods sets self.breakConnection to True.
- If a "socketShutdown" message arrives on inbox "control"
The main() method divides the connection into effectively two main states:
- accepting random commands prior to getting a DATA command
- accepting the email during a DATA command
SMTP commands are specifically dispatched to a particular handler for that
command. In this component none of the handlers do anything interesting.
Configuration
-------------
The abstract mailer supports some basic config settings:
- logfile - path/filename where requests should get logged
- debuglogfile - path/filename to where the debug log file should do.
Methods you are expected to override
------------------------------------
Whilst you are probably better off subclassing ConcreteMailHandler, you will
probably need to override the following methods in a subclass if you
subclass MailHandler directly.
- handleConnect(self)
- handleHelo(self,command)
- handleEhlo(self,command)
- handleMail(self,command)
- handleRcpt(self,command)
- handleData(self,command)
- handleQuit(self,command)
- handleRset(self,command)
- handleNoop(self,command)
- handleVrfy(self,command)
- handleHelp(self,command)
- logResult(self)
- handleDisconnect(self)

"""Gamma distribution.
The Gamma distribution is defined over positive real numbers using
parameters `concentration` (aka "alpha") and `rate` (aka "beta").
#### Mathematical Details
The probability density function (pdf) is,
```none
pdf(x; alpha, beta, x > 0) = x**(alpha - 1) exp(-x beta) / Z
Z = Gamma(alpha) beta**(-alpha)
```
where:
* `concentration = alpha`, `alpha > 0`,
* `rate = beta`, `beta > 0`,
* `Z` is the normalizing constant, and,
* `Gamma` is the [gamma function](
https://en.wikipedia.org/wiki/Gamma_function).
The cumulative density function (cdf) is,
```none
cdf(x; alpha, beta, x > 0) = GammaInc(alpha, beta x) / Gamma(alpha)
```
where `GammaInc` is the [lower incomplete Gamma function](
https://en.wikipedia.org/wiki/Incomplete_gamma_function).
The parameters can be intuited via their relationship to mean and stddev,
```none
concentration = alpha = (mean / stddev)**2
rate = beta = mean / stddev**2 = concentration / mean
```
Distribution parameters are automatically broadcast in all functions; see
examples for details.
Warning: The samples of this distribution are always non-negative. However,
the samples that are smaller than `np.finfo(dtype).tiny` are rounded
to this value, so it appears more often than it should.
This should only be noticeable when the `concentration` is very small, or the
`rate` is very large. See note in `tf.random_gamma` docstring.
Samples of this distribution are reparameterized (pathwise differentiable).
The derivatives are computed using the approach described in the paper
[Michael Figurnov, Shakir Mohamed, Andriy Mnih.
Implicit Reparameterization Gradients, 2018](https://arxiv.org/abs/1805.08498)
#### Examples
```python
import tensorflow_probability as tfp
tfd = tfp.distributions
dist = tfd.Gamma(concentration=3.0, rate=2.0)
dist2 = tfd.Gamma(concentration=[3.0, 4.0], rate=[2.0, 3.0])
```
Compute the gradients of samples w.r.t. the parameters:
```python
concentration = tf.constant(3.0)
rate = tf.constant(2.0)
dist = tfd.Gamma(concentration, rate)
samples = dist.sample(5) # Shape [5]
loss = tf.reduce_mean(tf.square(samples)) # Arbitrary loss function
# Unbiased stochastic gradients of the loss function
grads = tf.gradients(loss, [concentration, rate])
```

"""A custom list that manages index/position information for contained
elements.
:author: Jason Kirtland
``orderinglist`` is a helper for mutable ordered relationships. It will
intercept list operations performed on a :func:`.relationship`-managed
collection and
automatically synchronize changes in list position onto a target scalar
attribute.
Example: A ``slide`` table, where each row refers to zero or more entries
in a related ``bullet`` table. The bullets within a slide are
displayed in order based on the value of the ``position`` column in the
``bullet`` table. As entries are reordered in memory, the value of the
``position`` attribute should be updated to reflect the new sort order::
Base = declarative_base()
class Slide(Base):
__tablename__ = 'slide'
id = Column(Integer, primary_key=True)
name = Column(String)
bullets = relationship("Bullet", order_by="Bullet.position")
class Bullet(Base):
__tablename__ = 'bullet'
id = Column(Integer, primary_key=True)
slide_id = Column(Integer, ForeignKey('slide.id'))
position = Column(Integer)
text = Column(String)
The standard relationship mapping will produce a list-like attribute on each
``Slide`` containing all related ``Bullet`` objects,
but coping with changes in ordering is not handled automatically.
When appending a ``Bullet`` into ``Slide.bullets``, the ``Bullet.position``
attribute will remain unset until manually assigned. When the ``Bullet``
is inserted into the middle of the list, the following ``Bullet`` objects
will also need to be renumbered.
The :class:`.OrderingList` object automates this task, managing the
``position`` attribute on all ``Bullet`` objects in the collection. It is
constructed using the :func:`.ordering_list` factory::
from sqlalchemy.ext.orderinglist import ordering_list
Base = declarative_base()
class Slide(Base):
__tablename__ = 'slide'
id = Column(Integer, primary_key=True)
name = Column(String)
bullets = relationship("Bullet", order_by="Bullet.position",
collection_class=ordering_list('position'))
class Bullet(Base):
__tablename__ = 'bullet'
id = Column(Integer, primary_key=True)
slide_id = Column(Integer, ForeignKey('slide.id'))
position = Column(Integer)
text = Column(String)
With the above mapping the ``Bullet.position`` attribute is managed::
s = Slide()
s.bullets.append(Bullet())
s.bullets.append(Bullet())
s.bullets[1].position
>>> 1
s.bullets.insert(1, Bullet())
s.bullets[2].position
>>> 2
The :class:`.OrderingList` construct only works with **changes** to a
collection, and not the initial load from the database, and requires that the
list be sorted when loaded. Therefore, be sure to specify ``order_by`` on the
:func:`.relationship` against the target ordering attribute, so that the
ordering is correct when first loaded.
.. warning::
:class:`.OrderingList` only provides limited functionality when a primary
key column or unique column is the target of the sort. Operations
that are unsupported or are problematic include:
* two entries must trade values. This is not supported directly in the
case of a primary key or unique constraint because it means at least
one row would need to be temporarily removed first, or changed to
a third, neutral value while the switch occurs.
* an entry must be deleted in order to make room for a new entry.
SQLAlchemy's unit of work performs all INSERTs before DELETEs within a
single flush. In the case of a primary key, it will trade
an INSERT/DELETE of the same primary key for an UPDATE statement in order
to lessen the impact of this limitation, however this does not take place
for a UNIQUE column.
A future feature will allow the "DELETE before INSERT" behavior to be
possible, allevating this limitation, though this feature will require
explicit configuration at the mapper level for sets of columns that
are to be handled in this way.
:func:`.ordering_list` takes the name of the related object's ordering
attribute as an argument. By default, the zero-based integer index of the
object's position in the :func:`.ordering_list` is synchronized with the
ordering attribute: index 0 will get position 0, index 1 position 1, etc. To
start numbering at 1 or some other integer, provide ``count_from=1``.

"""A custom list that manages position information for its children.
``OrderingList`` is a ``collection_class`` list implementation that
syncs position in a Python list with a position attribute on the
mapped objects.
This implementation relies on the list starting in the proper order,
so be **sure** to put an ``order_by`` on your relationship.
:param ordering_attr:
Name of the attribute that stores the object's order in the
relationship.
:param ordering_func: Optional. A function that maps the position in
the Python list to a value to store in the
``ordering_attr``. Values returned are usually (but need not be!)
integers.
An ``ordering_func`` is called with two positional parameters: the
index of the element in the list, and the list itself.
If omitted, Python list indexes are used for the attribute values.
Two basic pre-built numbering functions are provided in this module:
``count_from_0`` and ``count_from_1``. For more exotic examples
like stepped numbering, alphabetical and Fibonacci numbering, see
the unit tests.
:param reorder_on_append:
Default False. When appending an object with an existing (non-None)
ordering value, that value will be left untouched unless
``reorder_on_append`` is true. This is an optimization to avoid a
variety of dangerous unexpected database writes.
SQLAlchemy will add instances to the list via append() when your
object loads. If for some reason the result set from the database
skips a step in the ordering (say, row '1' is missing but you get
'2', '3', and '4'), reorder_on_append=True would immediately
renumber the items to '1', '2', '3'. If you have multiple sessions
making changes, any of whom happen to load this collection even in
passing, all of the sessions would try to "clean up" the numbering
in their commits, possibly causing all but one to fail with a
concurrent modification error.
Recommend leaving this with the default of False, and just call
``reorder()`` if you're doing ``append()`` operations with
previously ordered instances or when doing some housekeeping after
manual sql operations.

* Changes to files and folders are analyzed to check whether any
of the interesting resources are changed or not. If they are,
it reports these changes to `resource_observer` passed to the
constructor.
* When a resource is removed it checks whether any of the
interesting resources are contained in that folder and reports
them to `resource_observer`.
* When validating a folder it validates all of the interesting

Since most resource observers are interested in a list of
resources that change over time, `add_resource` and
`remove_resource` might be useful.

module: xattr
version_added: "1.3"
short_description: set/retrieve extended attributes
description:
- Manages filesystem user defined extended attributes, requires that they are enabled
on the target filesystem and that the setfattr/getfattr utilities are present.
options:
name:
required: true
default: None
aliases: ['path']
description:
- The full path of the file/object to get the facts of
key:
required: false
default: None
description:
- The name of a specific Extended attribute key to set/retrieve
value:
required: false
default: None
description:
- The value to set the named name/key to, it automatically sets the C(state) to 'set'
state:
required: false
default: get
choices: [ 'read', 'present', 'all', 'keys', 'absent' ]
description:
- defines which state you want to do.
C(read) retrieves the current value for a C(key) (default)
C(present) sets C(name) to C(value), default if value is set
C(all) dumps all data
C(keys) retrieves all keys
C(absent) deletes the key
follow:
required: false
default: yes
choices: [ 'yes', 'no' ]
description:
- if yes, dereferences symlinks and sets/gets attributes on symlink target,
otherwise acts on symlink itself.
author: "Brian Coca (@bcoca)"

"""Profiler for TensorFlow models that outputs data in pprof format.
See https://github.com/google/pprof/blob/master/proto/profile.proto for pprof
profile format.
The following needs to be set for profiler to work:
* trace_level needs to be set to FULL_TRACE
* run_metadata object should be passed in to session.run call
Sample usage:
options = tf.RunOptions(trace_level=tf.RunOptions.FULL_TRACE)
run_metadata = tf.RunMetadata()
with tf.Session as sess:
...
sess.run(computation, run_metadata=run_metadata, options=options)
pprof_profiler.profile(sess.graph, run_metadata, output_dir)
The code above would output a pprof profile to separate output_dir/.*.pb.gz
file for each device. These files can be passed to pprof for formatting.
For e.g.:
pprof -png --nodecount=100 --sample_index=1 output_dir/profile_output.pb.gz

allow certain types of access for additional users.

account, list objects in any container, retrieve objects, and view
unprivileged account/container/object metadata.
* Read-Write: Users with read-write access can (in addition to the
read-only privileges) create objects, overwrite existing objects,
create new containers, and set unprivileged container/object
metadata.
* Admin: Users with admin access are swift_owners and can perform
any action, including viewing/setting privileged metadata (e.g.
changing account ACLs).

TODO: (here and __init__)
* search based on label, review, or other annotations (possible?)
* edit (specifically, Put requests) seem to fail effect a change
Problems With API:
* Adding a book with a review to the library adds a note, not a review.
This does not get included in the returned item. You see this by
looking at My Library through the website.
* Editing a review never edits a review (unless it is freshly added, but
see above). More generally,
* a Put request with changed annotations (label/rating/review) does NOT
change the data. Note: Put requests only work on the href from
GetEditLink (as per the spec). Do not try to PUT to the annotate or
library feeds, this will cause a 400 Invalid URI Bad Request response.
Attempting to Post to one of the feeds with the updated annotations
does not update them. See the following for (hopefully) a follow up:
google.com/support/forum/p/booksearch-apis/thread?tid=27fd7f68de438fc8
* Attempts to workaround the edit problem continue to fail. For example,
removing the item, editing the data, readding the item, gives us only
our originally added data (annotations). This occurs even if we
completely shut python down, refetch the book from the public feed,
and re-add it. There is some kind of persistence going on that I
cannot change. This is likely due to the annotations being cached in
the annotation feed and the inability to edit (see Put, above)
* GetAnnotationLink has www.books.... as the server, but hitting www...
results in a bad URI error.
* Spec indicates there may be multiple labels, but there does not seem
to be a way to get the server to accept multiple labels, nor does the
web interface have an obvious way to have multiple labels. Multiple
labels are never returned.

This is an example dag for using `AWSDataSyncOperator` in a more complex manner.
- Try to get a TaskArn. If one exists, update it.
- If no tasks exist, try to create a new DataSync Task.
- If source and destination locations don't exist for the new task, create them first
- If many tasks exist, raise an Exception
- After getting or creating a DataSync Task, run it
This DAG relies on the following environment variables:
* SOURCE_LOCATION_URI - Source location URI, usually on premises SMB or NFS

--------------------
A resource is a logical file contained within a package, or a logical
subdirectory thereof. The package resource API expects resource names
to have their path parts separated with ``/``, *not* whatever the local
path separator is. Do not use os.path operations to manipulate resource
names being passed into the API.
The package resource API is designed to work with normal filesystem packages,
.egg files, and unpacked .egg files. It can also work in a limited way with
.zip files and with custom PEP 302 loaders that support the ``get_data()``
method.

"""Convert a version string to a chronologically-sortable key
This is a rough cross between distutils' StrictVersion and LooseVersion;
if you give it versions that would work with StrictVersion, then it behaves
the same; otherwise it acts like a slightly-smarter LooseVersion. It is
*possible* to create pathological version coding schemes that will fool
this parser, but they should be very rare in practice.
The returned value will be a tuple of strings. Numeric portions of the
version are padded to 8 digits so they will compare numerically, but
without relying on how numbers compare relative to strings. Dots are
dropped, but dashes are retained. Trailing zeros between alpha segments
or dashes are suppressed, so that e.g. "2.4.0" is considered the same as
"2.4". Alphanumeric parts are lower-cased.
The algorithm assumes that strings like "-" and any alpha string that
alphabetically follows "final" represents a "patch level". So, "2.4-1"
is assumed to be a branch or patch of "2.4", and therefore "2.4.1" is
considered newer than "2.4-1", which in turn is newer than "2.4".
Strings like "a", "b", "c", "alpha", "beta", "candidate" and so on (that
come before "final" alphabetically) are assumed to be pre-release versions,
so that the version "2.4" is considered newer than "2.4a1".
Finally, to handle miscellaneous cases, the strings "pre", "preview", and
"rc" are treated as if they were "c", i.e. as though they were release
candidates, and therefore are not as new as a version string that does not
contain them, and "dev" is replaced with an '@' so that it sorts lower than
than any other pre-release tag.

XX. Model inheritance
Model inheritance exists in two varieties:
- abstract base classes which are a way of specifying common
information inherited by the subclasses. They don't exist as a separate
model.
- non-abstract base classes (the default), which are models in their own
right with their own database tables and everything. Their subclasses
have references back to them, created automatically.
Both styles are demonstrated here.
