"""Support for the PostgreSQL database.
For information on connecting using specific drivers, see the documentation
section regarding that driver.
Sequences/SERIAL
----------------
PostgreSQL supports sequences, and SQLAlchemy uses these as the default means
of creating new primary key values for integer-based primary key columns. When
creating tables, SQLAlchemy will issue the ``SERIAL`` datatype for
integer-based primary key columns, which generates a sequence and server side
default corresponding to the column.
To specify a specific named sequence to be used for primary key generation,
use the :func:`~sqlalchemy.schema.Sequence` construct::
Table('sometable', metadata,
Column('id', Integer, Sequence('some_id_seq'), primary_key=True)
)
When SQLAlchemy issues a single INSERT statement, to fulfill the contract of
having the "last insert identifier" available, a RETURNING clause is added to
the INSERT statement which specifies the primary key columns should be
returned after the statement completes. The RETURNING functionality only takes
place if Postgresql 8.2 or later is in use. As a fallback approach, the
sequence, whether specified explicitly or implicitly via ``SERIAL``, is
executed independently beforehand, the returned value to be used in the
subsequent insert. Note that when an
:func:`~sqlalchemy.sql.expression.insert()` construct is executed using
"executemany" semantics, the "last inserted identifier" functionality does not
apply; no RETURNING clause is emitted nor is the sequence pre-executed in this
case.
To force the usage of RETURNING by default off, specify the flag
``implicit_returning=False`` to :func:`.create_engine`.
Transaction Isolation Level
---------------------------
:func:`.create_engine` accepts an ``isolation_level`` parameter which results
in the command ``SET SESSION CHARACTERISTICS AS TRANSACTION ISOLATION LEVEL
<level>`` being invoked for every new connection. Valid values for this
parameter are ``READ_COMMITTED``, ``READ_UNCOMMITTED``, ``REPEATABLE_READ``,
and ``SERIALIZABLE``. Note that the psycopg2 dialect does *not* use this
technique and uses psycopg2-specific APIs (see that dialect for details).
INSERT/UPDATE...RETURNING
-------------------------
The dialect supports PG 8.2's ``INSERT..RETURNING``, ``UPDATE..RETURNING`` and
``DELETE..RETURNING`` syntaxes. ``INSERT..RETURNING`` is used by default
for single-row INSERT statements in order to fetch newly generated
primary key identifiers. To specify an explicit ``RETURNING`` clause,
use the :meth:`._UpdateBase.returning` method on a per-statement basis::
# INSERT..RETURNING
result = table.insert().returning(table.c.col1, table.c.col2).\\
values(name='foo')
print result.fetchall()
# UPDATE..RETURNING
result = table.update().returning(table.c.col1, table.c.col2).\\
where(table.c.name=='foo').values(name='bar')
print result.fetchall()
# DELETE..RETURNING
result = table.delete().returning(table.c.col1, table.c.col2).\\
where(table.c.name=='foo')
print result.fetchall()
Indexes
-------
PostgreSQL supports partial indexes. To create them pass a postgresql_where
option to the Index constructor::
Index('my_index', my_table.c.id, postgresql_where=tbl.c.value > 10)

If the mask (portion after the / in the argument) is given in
dotted quad form, it is treated as a netmask if it starts with a
non-zero field (e.g. /255.0.0.0 == /8) and as a hostmask if it
starts with a zero field (e.g. 0.255.255.255 == /8), with the
single exception of an all-zero mask which is treated as a
netmask == /0. If no mask is given, a default of /32 is used.

This file implements the main() function used by the scons script.
Architecturally, this *is* the scons script, and will likely only be
called from the external "scons" wrapper. Consequently, anything here
should not be, or be considered, part of the build engine. If it's
something that we expect other software to want to use, it should go in
some other module. If it's specific to the "scons" script invocation,
it goes here.

# SCons.Memoize contains a metaclass implementation that affects how
# the other classes are instantiated. The Memoizer may add shim methods
# to classes that have methods that cache computed values in order to
# count and report the hits and misses.
#
# If we wait to enable the Memoization until after we've parsed the
# command line options normally, it will be too late, because the Memoizer
# will have already analyzed the classes that it's Memoizing and decided
# to not add the shims. So we use a special-case, up-front check for

module: cnos_vlag
author: "Dave Kasberg (@dkasberg)"
short_description: Manage VLAG resources and attributes on devices running Lenovo CNOS
description:
- This module allows you to work with virtual Link Aggregation Groups
(vLAG) related configurations. The operators used are overloaded to ensure
control over switch vLAG configurations. Apart from the regular device
connection related attributes, there are four vLAG arguments which are
overloaded variables that will perform further configurations. They are
vlagArg1, vlagArg2, vlagArg3, and vlagArg4. For more details on how to use
these arguments, see [Overloaded Variables].
This module uses SSH to manage network device configuration.
The results of the operation will be placed in a directory named 'results'
that must be created by the user in their local directory to where the playbook is run.
For more information about this module from Lenovo and customizing it usage for your
use cases, please visit U(http://systemx.lenovofiles.com/help/index.jsp?topic=%2Fcom.lenovo.switchmgt.ansible.doc%2Fcnos_vlag.html)

module: template
version_added: historical
short_description: Templates a file out to a remote server.
description:
- Templates are processed by the Jinja2 templating language
(U(http://jinja.pocoo.org/docs/)) - documentation on the template
formatting can be found in the Template Designer Documentation
(U(http://jinja.pocoo.org/docs/templates/)).
- "Six additional variables can be used in templates: C(ansible_managed)
(configurable via the C(defaults) section of C(ansible.cfg)) contains a string
which can be used to describe the template name, host, modification time of the
template file and the owner uid, C(template_host) contains the node name of
the template's machine, C(template_uid) the owner, C(template_path) the
absolute path of the template, C(template_fullpath) is the absolute path of the
template, and C(template_run_date) is the date that the template was rendered. Note that including
a string that uses a date in the template will result in the template being marked 'changed'
each time."
options:
src:
description:
- Path of a Jinja2 formatted template on the Ansible controller. This can be a relative or absolute path.
required: true
dest:
description:
- Location to render the template to on the remote machine.
required: true
backup:
description:
- Create a backup file including the timestamp information so you can get
the original file back if you somehow clobbered it incorrectly.
required: false
choices: [ "yes", "no" ]
default: "no"
force:
description:
- the default is C(yes), which will replace the remote file when contents
are different than the source. If C(no), the file will only be transferred
if the destination does not exist.
required: false
choices: [ "yes", "no" ]
default: "yes"
notes:
- "Since Ansible version 0.9, templates are loaded with C(trim_blocks=True)."
- "Also, you can override jinja2 settings by adding a special header to template file.
i.e. C(#jinja2:variable_start_string:'[%' , variable_end_string:'%]', trim_blocks: False)
which changes the variable interpolation markers to [% var %] instead of {{ var }}.
This is the best way to prevent evaluation of things that look like, but should not be Jinja2.
raw/endraw in Jinja2 will not work as you expect because templates in Ansible are recursively evaluated."

Just .close() the object when you're done with it.

If-None-Match request header.
If the modified argument is supplied, it can be a tuple of 9 integers
(as returned by gmtime() in the standard Python time module) or a date
string in any format supported by feedparser. Regardless, it MUST
be in GMT (Greenwich Mean Time). It will be reformatted into an
RFC 1123-compliant date and used as the value of an If-Modified-Since
request header.
If the agent argument is supplied, it will be used as the value of a
User-Agent request header.
If the referrer argument is supplied, it will be used as the value of a
Referer[sic] request header.
If handlers is supplied, it is a list of handlers used to build a

# 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.

"""
This is the common settings file, intended to set sane defaults. If you have a
piece of configuration that's dependent on a set of feature flags being set,
then create a function that returns the calculated value based on the value of
FEATURES[...]. Modules that extend this one can change the feature
configuration in an environment specific config file and re-calculate those
values.
We should make a method that calls all these config methods so that you just
make one call at the end of your site-specific dev file to reset all the
dependent variables (like INSTALLED_APPS) for you.
Longer TODO:
1. Right now our treatment of static content in general and in particular
course-specific static content is haphazard.
2. We should have a more disciplined approach to feature flagging, even if it
just means that we stick them in a dict called FEATURES.
3. We need to handle configuration for multiple courses. This could be as
multiple sites, but we do need a way to map their data assets.

the response's content immediately. You will need to call

"""Xcode project file generator.
This module is both an Xcode project file generator and a documentation of the
Xcode project file format. Knowledge of the project file format was gained
based on extensive experience with Xcode, and by making changes to projects in
Xcode.app and observing the resultant changes in the associated project files.
XCODE PROJECT FILES
The generator targets the file format as written by Xcode 3.2 (specifically,
3.2.6), but past experience has taught that the format has not changed
significantly in the past several years, and future versions of Xcode are able
to read older project files.
Xcode project files are "bundled": the project "file" from an end-user's
perspective is actually a directory with an ".xcodeproj" extension. The
project file from this module's perspective is actually a file inside this
directory, always named "project.pbxproj". This file contains a complete
description of the project and is all that is needed to use the xcodeproj.
Other files contained in the xcodeproj directory are simply used to store
per-user settings, such as the state of various UI elements in the Xcode
application.
The project.pbxproj file is a property list, stored in a format almost
identical to the NeXTstep property list format. The file is able to carry
Unicode data, and is encoded in UTF-8. The root element in the property list
is a dictionary that contains several properties of minimal interest, and two
properties of immense interest. The most important property is a dictionary
named "objects". The entire structure of the project is represented by the
children of this property. The objects dictionary is keyed by unique 96-bit
values represented by 24 uppercase hexadecimal characters. Each value in the
objects dictionary is itself a dictionary, describing an individual object.
Each object in the dictionary is a member of a class, which is identified by
the "isa" property of each object. A variety of classes are represented in a
project file. Objects can refer to other objects by ID, using the 24-character
hexadecimal object key. A project's objects form a tree, with a root object
of class PBXProject at the root. As an example, the PBXProject object serves
as parent to an XCConfigurationList object defining the build configurations
used in the project, a PBXGroup object serving as a container for all files
referenced in the project, and a list of target objects, each of which defines
a target in the project. There are several different types of target object,
such as PBXNativeTarget and PBXAggregateTarget. In this module, this
relationship is expressed by having each target type derive from an abstract
base named XCTarget.
The project.pbxproj file's root dictionary also contains a property, sibling to
the "objects" dictionary, named "rootObject". The value of rootObject is a
24-character object key referring to the root PBXProject object in the
objects dictionary.
In Xcode, every file used as input to a target or produced as a final product
of a target must appear somewhere in the hierarchy rooted at the PBXGroup
object referenced by the PBXProject's mainGroup property. A PBXGroup is
generally represented as a folder in the Xcode application. PBXGroups can
contain other PBXGroups as well as PBXFileReferences, which are pointers to
actual files.
Each XCTarget contains a list of build phases, represented in this module by
the abstract base XCBuildPhase. Examples of concrete XCBuildPhase derivations
are PBXSourcesBuildPhase and PBXFrameworksBuildPhase, which correspond to the
"Compile Sources" and "Link Binary With Libraries" phases displayed in the
Xcode application. Files used as input to these phases (for example, source
files in the former case and libraries and frameworks in the latter) are
represented by PBXBuildFile objects, referenced by elements of "files" lists
in XCTarget objects. Each PBXBuildFile object refers to a PBXBuildFile
object as a "weak" reference: it does not "own" the PBXBuildFile, which is
owned by the root object's mainGroup or a descendant group. In most cases, the
layer of indirection between an XCBuildPhase and a PBXFileReference via a
PBXBuildFile appears extraneous, but there's actually one reason for this:
file-specific compiler flags are added to the PBXBuildFile object so as to
allow a single file to be a member of multiple targets while having distinct
compiler flags for each. These flags can be modified in the Xcode applciation
in the "Build" tab of a File Info window.
When a project is open in the Xcode application, Xcode will rewrite it. As
such, this module is careful to adhere to the formatting used by Xcode, to
avoid insignificant changes appearing in the file when it is used in the
Xcode application. This will keep version control repositories happy, and
makes it possible to compare a project file used in Xcode to one generated by
this module to determine if any significant changes were made in the
application.
Xcode has its own way of assigning 24-character identifiers to each object,
which is not duplicated here. Because the identifier only is only generated
once, when an object is created, and is then left unchanged, there is no need
to attempt to duplicate Xcode's behavior in this area. The generator is free
to select any identifier, even at random, to refer to the objects it creates,
and Xcode will retain those identifiers and use them when subsequently
rewriting the project file. However, the generator would choose new random
identifiers each time the project files are generated, leading to difficulties
comparing "used" project files to "pristine" ones produced by this module,
and causing the appearance of changes as every object identifier is changed
when updated projects are checked in to a version control repository. To
mitigate this problem, this module chooses identifiers in a more deterministic
way, by hashing a description of each object as well as its parent and ancestor
objects. This strategy should result in minimal "shift" in IDs as successive
generations of project files are produced.
THIS MODULE
This module introduces several classes, all derived from the XCObject class.
Nearly all of the "brains" are built into the XCObject class, which understands
how to create and modify objects, maintain the proper tree structure, compute
identifiers, and print objects. For the most part, classes derived from
XCObject need only provide a _schema class object, a dictionary that
expresses what properties objects of the class may contain.
Given this structure, it's possible to build a minimal project file by creating
objects of the appropriate types and making the proper connections:
config_list = XCConfigurationList()
group = PBXGroup()
project = PBXProject({'buildConfigurationList': config_list,
'mainGroup': group})
With the project object set up, it can be added to an XCProjectFile object.
XCProjectFile is a pseudo-class in the sense that it is a concrete XCObject
subclass that does not actually correspond to a class type found in a project
file. Rather, it is used to represent the project file's root dictionary.
Printing an XCProjectFile will print the entire project file, including the
full "objects" dictionary.
project_file = XCProjectFile({'rootObject': project})
project_file.ComputeIDs()
project_file.Print()
Xcode project files are always encoded in UTF-8. This module will accept
strings of either the str class or the unicode class. Strings of class str
are assumed to already be encoded in UTF-8. Obviously, if you're just using
ASCII, you won't encounter difficulties because ASCII is a UTF-8 subset.
Strings of class unicode are handled properly and encoded in UTF-8 when
a project file is output.

"""The abstract base of all class types used in Xcode project files.
Class variables:
_schema: A dictionary defining the properties of this class. The keys to
_schema are string property keys as used in project files. Values
are a list of four or five elements:
[ is_list, property_type, is_strong, is_required, default ]
is_list: True if the property described is a list, as opposed
to a single element.
property_type: The type to use as the value of the property,
or if is_list is True, the type to use for each
element of the value's list. property_type must
be an XCObject subclass, or one of the built-in
types str, int, or dict.
is_strong: If property_type is an XCObject subclass, is_strong
is True to assert that this class "owns," or serves
as parent, to the property value (or, if is_list is
True, values). is_strong must be False if
property_type is not an XCObject subclass.
is_required: True if the property is required for the class.
Note that is_required being True does not preclude
an empty string ("", in the case of property_type
str) or list ([], in the case of is_list True) from
being set for the property.
default: Optional. If is_requried is True, default may be set
to provide a default value for objects that do not supply
their own value. If is_required is True and default
is not provided, users of the class must supply their own
value for the property.
Note that although the values of the array are expressed in
boolean terms, subclasses provide values as integers to conserve
horizontal space.
_should_print_single_line: False in XCObject. Subclasses whose objects
should be written to the project file in the
alternate single-line format, such as
PBXFileReference and PBXBuildFile, should
set this to True.
_encode_transforms: Used by _EncodeString to encode unprintable characters.
The index into this list is the ordinal of the
character to transform; each value is a string
used to represent the character in the output. XCObject
provides an _encode_transforms list suitable for most
XCObject subclasses.
_alternate_encode_transforms: Provided for subclasses that wish to use
the alternate encoding rules. Xcode seems
to use these rules when printing objects in
single-line format. Subclasses that desire
this behavior should set _encode_transforms
to _alternate_encode_transforms.
_hashables: A list of XCObject subclasses that can be hashed by ComputeIDs
to construct this object's ID. Most classes that need custom
hashing behavior should do it by overriding Hashables,
but in some cases an object's parent may wish to push a
hashable value into its child, and it can do so by appending
to _hashables.
Attribues:
id: The object's identifier, a 24-character uppercase hexadecimal string.
Usually, objects being created should not set id until the entire
project file structure is built. At that point, UpdateIDs() should
be called on the root object to assign deterministic values for id to
each object in the tree.
parent: The object's parent. This is set by a parent XCObject when a child
object is added to it.
_properties: The object's property dictionary. An object's properties are
described by its class' _schema variable.

XCHierarchicalElements are special. Generally, their hashes shouldn't
change if the paths don't change. The normal XCObject implementation of
Hashables adds a hashable for each object, which means that if
the hierarchical structure changes (possibly due to changes caused when
TakeOverOnlyChild runs and encounters slight changes in the hierarchy),
the hashes will change. For example, if a project file initially contains
a/b/f1 and a/b becomes collapsed into a/b, f1 will have a single parent
a/b. If someone later adds a/f2 to the project file, a/b can no longer be
collapsed, and f1 winds up with parent b and grandparent a. That would
be sufficient to change f1's hash.
To counteract this problem, hashables for all XCHierarchicalElements except
for the main group (which has neither a name nor a path) are taken to be
just the set of path components. Because hashables are inherited from
parents, this provides assurance that a/b/f1 has the same set of hashables
whether its parent is b or a/b.
The main group is a special case. As it is permitted to have no name or
path, it is permitted to use the standard XCObject hash mechanism. This
