|
||||
The Python SQL Toolkit and Object Relational Mapper
|
||||
|
||||
Introduction
|
||||
-------------
|
||||
|
||||
SQLAlchemy is the Python SQL toolkit and Object Relational Mapper
|
||||
that gives application developers the full power and
|
||||
flexibility of SQL. SQLAlchemy provides a full suite
|
||||
of well known enterprise-level persistence patterns,
|
||||
designed for efficient and high-performing database
|
||||
access, adapted into a simple and Pythonic domain
|
||||
language.
|
||||
|
||||
Major SQLAlchemy features include:
|
||||
|
||||
* An industrial strength ORM, built
|
||||
from the core on the identity map, unit of work,
|
||||
and data mapper patterns. These patterns
|
||||
allow transparent persistence of objects
|
||||
using a declarative configuration system.
|
||||
Domain models
|
||||
can be constructed and manipulated naturally,
|
||||
and changes are synchronized with the
|
||||
current transaction automatically.
|
||||
* A relationally-oriented query system, exposing
|
||||
the full range of SQL's capabilities
|
||||
explicitly, including joins, subqueries,
|
||||
correlation, and most everything else,
|
||||
in terms of the object model.
|
||||
Writing queries with the ORM uses the same
|
||||
techniques of relational composition you use
|
||||
when writing SQL. While you can drop into
|
||||
literal SQL at any time, it's virtually never
|
||||
needed.
|
||||
* A comprehensive and flexible system
|
||||
of eager loading for related collections and objects.
|
||||
Collections are cached within a session,
|
||||
and can be loaded on individual access, all
|
||||
at once using joins, or by query per collection
|
||||
across the full result set.
|
||||
* A Core SQL construction system and DBAPI
|
||||
interaction layer. The SQLAlchemy Core is
|
||||
separate from the ORM and is a full database
|
||||
abstraction layer in its own right, and includes
|
||||
an extensible Python-based SQL expression
|
||||
language, schema metadata, connection pooling,
|
||||
type coercion, and custom types.
|
||||
* All primary and foreign key constraints are
|
||||
assumed to be composite and natural. Surrogate
|
||||
integer primary keys are of course still the
|
||||
norm, but SQLAlchemy never assumes or hardcodes
|
||||
to this model.
|
||||
* Database introspection and generation. Database
|
||||
schemas can be "reflected" in one step into
|
||||
Python structures representing database metadata;
|
||||
those same structures can then generate
|
||||
CREATE statements right back out - all within
|
||||
the Core, independent of the ORM.
|
||||
|
||||
SQLAlchemy's philosophy:
|
||||
|
||||
* SQL databases behave less and less like object
|
||||
collections the more size and performance start to
|
||||
matter; object collections behave less and less like
|
||||
tables and rows the more abstraction starts to matter.
|
||||
SQLAlchemy aims to accommodate both of these
|
||||
principles.
|
||||
* An ORM doesn't need to hide the "R". A relational
|
||||
database provides rich, set-based functionality
|
||||
that should be fully exposed. SQLAlchemy's
|
||||
ORM provides an open-ended set of patterns
|
||||
that allow a developer to construct a custom
|
||||
mediation layer between a domain model and
|
||||
a relational schema, turning the so-called
|
||||
"object relational impedance" issue into
|
||||
a distant memory.
|
||||
* The developer, in all cases, makes all decisions
|
||||
regarding the design, structure, and naming conventions
|
||||
of both the object model as well as the relational
|
||||
schema. SQLAlchemy only provides the means
|
||||
to automate the execution of these decisions.
|
||||
* With SQLAlchemy, there's no such thing as
|
||||
"the ORM generated a bad query" - you
|
||||
retain full control over the structure of
|
||||
queries, including how joins are organized,
|
||||
how subqueries and correlation is used, what
|
||||
columns are requested. Everything SQLAlchemy
|
||||
does is ultimately the result of a developer-
|
||||
initiated decision.
|
||||
* Don't use an ORM if the problem doesn't need one.
|
||||
SQLAlchemy consists of a Core and separate ORM
|
||||
component. The Core offers a full SQL expression
|
||||
language that allows Pythonic construction
|
||||
of SQL constructs that render directly to SQL
|
||||
strings for a target database, returning
|
||||
result sets that are essentially enhanced DBAPI
|
||||
cursors.
|
||||
* Transactions should be the norm. With SQLAlchemy's
|
||||
ORM, nothing goes to permanent storage until
|
||||
commit() is called. SQLAlchemy encourages applications
|
||||
to create a consistent means of delineating
|
||||
the start and end of a series of operations.
|
||||
* Never render a literal value in a SQL statement.
|
||||
Bound parameters are used to the greatest degree
|
||||
possible, allowing query optimizers to cache
|
||||
query plans effectively and making SQL injection
|
||||
attacks a non-issue.

This offers a comfortable python interface to a C implementation of the
|
||||
Ed25519 public-key signature system (http://ed25519.cr.yp.to/), using the
|
||||
portable 'ref' code from the 'SUPERCOP' benchmarking suite.
|
||||
|
||||
This system provides high (128-bit) security, short (32-byte) keys, short
|
||||
(64-byte) signatures, and fast (2-6ms) operation. Please see the README for
|
||||
more details.

1. What is this?
|
||||
----------------
|
||||
|
||||
It's been annoying me for some time that there's no easy way to get the
|
||||
address(es) of the machine's network interfaces from Python. There is
|
||||
a good reason for this difficulty, which is that it is virtually impossible
|
||||
to do so in a portable manner. However, it seems to me that there should
|
||||
be a package you can easy_install that will take care of working out the
|
||||
details of doing so on the machine you're using, then you can get on with
|
||||
writing Python code without concerning yourself with the nitty gritty of
|
||||
system-dependent low-level networking APIs.
|
||||
|
||||
This package attempts to solve that problem.
|
||||
|
||||
2. How do I use it?
|
||||
-------------------
|
||||
|
||||
First you need to install it, which you can do by typing::
|
||||
|
||||
tar xvzf netifaces-0.10.4.tar.gz
|
||||
cd netifaces-0.10.4
|
||||
python setup.py install
|
||||
|
||||
Once that's done, you'll need to start Python and do something like the
|
||||
following::
|
||||
|
||||
>>> import netifaces
|
||||
|
||||
Then if you enter
|
||||
|
||||
>>> netifaces.interfaces()
|
||||
['lo0', 'gif0', 'stf0', 'en0', 'en1', 'fw0']
|
||||
|
||||
you'll see the list of interface identifiers for your machine.
|
||||
|
||||
You can ask for the addresses of a particular interface by doing
|
||||
|
||||
>>> netifaces.ifaddresses('lo0')
|
||||
{18: [{'addr': ''}], 2: [{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}], 30: [{'peer': '::1', 'netmask': 'ffff:ffff:ffff:ffff:ffff:ffff:ffff:ffff', 'addr': '::1'}, {'peer': '', 'netmask': 'ffff:ffff:ffff:ffff::', 'addr': 'fe80::1%lo0'}]}
|
||||
|
||||
Hmmmm. That result looks a bit cryptic; let's break it apart and explain
|
||||
what each piece means. It returned a dictionary, so let's look there first::
|
||||
|
||||
{ 18: [...], 2: [...], 30: [...] }
|
||||
|
||||
Each of the numbers refers to a particular address family. In this case, we
|
||||
have three address families listed; on my system, 18 is ``AF_LINK`` (which means
|
||||
the link layer interface, e.g. Ethernet), 2 is ``AF_INET`` (normal Internet
|
||||
addresses), and 30 is ``AF_INET6`` (IPv6).
|
||||
|
||||
But wait! Don't use these numbers in your code. The numeric values here are
|
||||
system dependent; fortunately, I thought of that when writing netifaces, so
|
||||
the module declares a range of values that you might need. e.g.
|
||||
|
||||
>>> netifaces.AF_LINK
|
||||
18
|
||||
|
||||
Again, on your system, the number may be different.
|
||||
|
||||
So, what we've established is that the dictionary that's returned has one
|
||||
entry for each address family for which this interface has an address. Let's
|
||||
take a look at the ``AF_INET`` addresses now:
|
||||
|
||||
>>> addrs = netifaces.ifaddresses('lo0')
|
||||
>>> addrs[netifaces.AF_INET]
|
||||
[{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}]
|
||||
|
||||
You might be wondering why this value is a list. The reason is that it's
|
||||
possible for an interface to have more than one address, even within the
|
||||
same family. I'll say that again: *you can have more than one address of
|
||||
the same type associated with each interface*.
|
||||
|
||||
*Asking for "the" address of a particular interface doesn't make sense.*
|
||||
|
||||
Right, so, we can see that this particular interface only has one address,
|
||||
and, because it's a loopback interface, it's point-to-point and therefore
|
||||
has a *peer* address rather than a broadcast address.
|
||||
|
||||
Let's look at a more interesting interface.
|
||||
|
||||
>>> addrs = netifaces.ifaddresses('en0')
|
||||
>>> addrs[netifaces.AF_INET]
|
||||
[{'broadcast': '10.15.255.255', 'netmask': '255.240.0.0', 'addr': '10.0.1.4'}, {'broadcast': '192.168.0.255', 'addr': '192.168.0.47'}]
|
||||
|
||||
This interface has two addresses (see, I told you...) Both of them are
|
||||
regular IPv4 addresses, although in one case the netmask has been changed
|
||||
from its default. The netmask *may not* appear on your system if it's set
|
||||
to the default for the address range.
|
||||
|
||||
Because this interface isn't point-to-point, it also has broadcast addresses.
|
||||
|
||||
Now, say we want, instead of the IP addresses, to get the MAC address; that
|
||||
is, the hardware address of the Ethernet adapter running this interface. We
|
||||
can do
|
||||
|
||||
>>> addrs[netifaces.AF_LINK]
|
||||
[{'addr': '00:12:34:56:78:9a'}]
|
||||
|
||||
Note that this may not be available on platforms without getifaddrs(), unless
|
||||
they happen to implement ``SIOCGIFHWADDR``. Note also that you just get the
|
||||
address; it's unlikely that you'll see anything else with an ``AF_LINK`` address.
|
||||
Oh, and don't assume that all ``AF_LINK`` addresses are Ethernet; you might, for
|
||||
instance, be on a Mac, in which case:
|
||||
|
||||
>>> addrs = netifaces.ifaddresses('fw0')
|
||||
>>> addrs[netifaces.AF_LINK]
|
||||
[{'addr': '00:12:34:56:78:9a:bc:de'}]
|
||||
|
||||
No, that isn't an exceptionally long Ethernet MAC address---it's a FireWire
|
||||
address.
|
||||
|
||||
As of version 0.10.0, you can also obtain a list of gateways on your
|
||||
machine:
|
||||
|
||||
>>> netifaces.gateways()
|
||||
{2: [('10.0.1.1', 'en0', True), ('10.2.1.1', 'en1', False)], 30: [('fe80::1', 'en0', True)], 'default': { 2: ('10.0.1.1', 'en0'), 30: ('fe80::1', 'en0') }}
|
||||
|
||||
This dictionary is keyed on address family---in this case, ``AF_INET``---and
|
||||
each entry is a list of gateways as ``(address, interface, is_default)`` tuples.
|
||||
Notice that here we have two separate gateways for IPv4 (``AF_INET``); some
|
||||
operating systems support configurations like this and can either route packets
|
||||
based on their source, or based on administratively configured routing tables.
|
||||
|
||||
For convenience, we also allow you to index the dictionary with the special
|
||||
value ``'default'``, which returns a dictionary mapping address families to the
|
||||
default gateway in each case. Thus you can get the default IPv4 gateway with
|
||||
|
||||
>>> gws = netifaces.gateways()
|
||||
>>> gws['default'][netifaces.AF_INET]
|
||||
('10.0.1.1', 'en0')
|
||||
|
||||
Do note that there may be no default gateway for any given address family;
|
||||
this is currently very common for IPv6 and much less common for IPv4 but it
|
||||
can happen even for ``AF_INET``.
|
||||
|
||||
BTW, if you're trying to configure your machine to have multiple gateways for
|
||||
the same address family, it's a very good idea to check the documentation for
|
||||
your operating system *very* carefully, as some systems become extremely
|
||||
confused or route packets in a non-obvious manner.
|
||||
|
||||
I'm very interested in hearing from anyone (on any platform) for whom the
|
||||
``gateways()`` method doesn't produce the expected results. It's quite
|
||||
complicated extracting this information from the operating system (whichever
|
||||
operating system we're talking about), and so I expect there's at least one
|
||||
system out there where this just won't work.
|
||||
|
||||
3. This is great! What platforms does it work on?
|
||||
--------------------------------------------------
|
||||
|
||||
It gets regular testing on OS X, Linux and Windows. It has also been used
|
||||
successfully on Solaris, and it's expected to work properly on other UNIX-like
|
||||
systems as well. If you are running something that is not supported, and
|
||||
wish to contribute a patch, please use BitBucket to send a pull request.
|
||||
|
||||
4. What license is this under?
|
||||
------------------------------
|
||||
|
||||
It's an MIT-style license. Here goes:

||||

5. Why the jump to 0.10.0?
|
||||
--------------------------
|
||||
|
||||
Because someone released a fork of netifaces with the version 0.9.0.
|
||||
Hopefully skipping the version number should remove any confusion. In
|
||||
addition starting with 0.10.0 Python 3 is now supported and other
|
||||
features/bugfixes have been included as well. See the CHANGELOG for a
|
||||
more complete list of changes.

||||
the module declares a range of values that you might need. e.g.
|
||||
|
||||
>>> netifaces.AF_LINK
|
||||
18
|
||||
|
||||
Again, on your system, the number may be different.
|
||||
|
||||
So, what we've established is that the dictionary that's returned has one
|
||||
entry for each address family for which this interface has an address. Let's
|
||||
take a look at the ``AF_INET`` addresses now:
|
||||
|
||||
>>> addrs = netifaces.ifaddresses('lo0')
|
||||
>>> addrs[netifaces.AF_INET]
|
||||
[{'peer': '127.0.0.1', 'netmask': '255.0.0.0', 'addr': '127.0.0.1'}]
|
||||
|
||||
You might be wondering why this value is a list. The reason is that it's
|
||||
possible for an interface to have more than one address, even within the
|
||||
same family. I'll say that again: *you can have more than one address of
|
||||
the same type associated with each interface*.
|
||||
|
||||
*Asking for "the" address of a particular interface doesn't make sense.*
|
||||
|
||||
Right, so, we can see that this particular interface only has one address,
|
||||
and, because it's a loopback interface, it's point-to-point and therefore
|
||||
has a *peer* address rather than a broadcast address.
|
||||
|
||||
Let's look at a more interesting interface.
|
||||
|
||||
>>> addrs = netifaces.ifaddresses('en0')
|
||||
>>> addrs[netifaces.AF_INET]
|
||||
[{'broadcast': '10.15.255.255', 'netmask': '255.240.0.0', 'addr': '10.0.1.4'}, {'broadcast': '192.168.0.255', 'addr': '192.168.0.47'}]
|
||||
|
||||
This interface has two addresses (see, I told you...) Both of them are
|
||||
regular IPv4 addresses, although in one case the netmask has been changed
|
||||
from its default. The netmask *may not* appear on your system if it's set
|
||||
to the default for the address range.
|
||||
|
||||
Because this interface isn't point-to-point, it also has broadcast addresses.
|
||||
|
||||
Now, say we want, instead of the IP addresses, to get the MAC address; that
|
||||
is, the hardware address of the Ethernet adapter running this interface. We
|
||||
can do
|
||||
|
||||
>>> addrs[netifaces.AF_LINK]
|
||||
[{'addr': '00:12:34:56:78:9a'}]
|
||||
|
||||
Note that this may not be available on platforms without getifaddrs(), unless
|
||||
they happen to implement ``SIOCGIFHWADDR``. Note also that you just get the
|
||||
address; it's unlikely that you'll see anything else with an ``AF_LINK`` address.
|
||||
Oh, and don't assume that all ``AF_LINK`` addresses are Ethernet; you might, for
|
||||
instance, be on a Mac, in which case:
|
||||
|
||||
>>> addrs = netifaces.ifaddresses('fw0')
|
||||
>>> addrs[netifaces.AF_LINK]
|
||||
[{'addr': '00:12:34:56:78:9a:bc:de'}]
|
||||
|
||||
No, that isn't an exceptionally long Ethernet MAC address---it's a FireWire
|
||||
address.
|
||||
|
||||
As of version 0.10.0, you can also obtain a list of gateways on your
|
||||
machine:
|
||||
|
||||
>>> netifaces.gateways()
|
||||
{2: [('10.0.1.1', 'en0', True), ('10.2.1.1', 'en1', False)], 30: [('fe80::1', 'en0', True)], 'default': { 2: ('10.0.1.1', 'en0'), 30: ('fe80::1', 'en0') }}
|
||||
|
||||
This dictionary is keyed on address family---in this case, ``AF_INET``---and
|
||||
each entry is a list of gateways as ``(address, interface, is_default)`` tuples.
|
||||
Notice that here we have two separate gateways for IPv4 (``AF_INET``); some
|
||||
operating systems support configurations like this and can either route packets
|
||||
based on their source, or based on administratively configured routing tables.
|
||||
|
||||
For convenience, we also allow you to index the dictionary with the special
|
||||
value ``'default'``, which returns a dictionary mapping address families to the
|
||||
default gateway in each case. Thus you can get the default IPv4 gateway with
|
||||
|
||||
>>> gws = netifaces.gateways()
|
||||
>>> gws['default'][netifaces.AF_INET]
|
||||
('10.0.1.1', 'en0')
|
||||
|
||||
Do note that there may be no default gateway for any given address family;
|
||||
this is currently very common for IPv6 and much less common for IPv4 but it
|
||||
can happen even for ``AF_INET``.
|
||||
|
||||
BTW, if you're trying to configure your machine to have multiple gateways for
|
||||
the same address family, it's a very good idea to check the documentation for
|
||||
your operating system *very* carefully, as some systems become extremely
|
||||
confused or route packets in a non-obvious manner.
|
||||
|
||||
I'm very interested in hearing from anyone (on any platform) for whom the
|
||||
``gateways()`` method doesn't produce the expected results. It's quite
|
||||
complicated extracting this information from the operating system (whichever
|
||||
operating system we're talking about), and so I expect there's at least one
|
||||
system out there where this just won't work.
|
||||
|
||||
3. This is great! What platforms does it work on?
|
||||
--------------------------------------------------
|
||||
|
||||
It gets regular testing on OS X, Linux and Windows. It has also been used
|
||||
successfully on Solaris, and it's expected to work properly on other UNIX-like
|
||||
systems as well. If you are running something that is not supported, and
|
||||
wish to contribute a patch, please use BitBucket to send a pull request.
|
||||
|
||||
4. What license is this under?
|
||||
------------------------------
|
||||
|
||||
It's an MIT-style license. Here goes:

||||

||||

|
||||
|
||||
5. Why the jump to 0.10.0?
|
||||
--------------------------
|
||||
|
||||
Because someone released a fork of netifaces with the version 0.9.0.
|
||||
Hopefully skipping the version number should remove any confusion. In
|
||||
addition starting with 0.10.0 Python 3 is now supported and other
|
||||
features/bugfixes have been included as well. See the CHANGELOG for a
|
||||
more complete list of changes.
