:mod:`anydbm` --- Generic access to DBM-style databases
=======================================================
.. module:: anydbm
:synopsis: Generic interface to DBM-style database modules.
.. index::
module: dbhash
module: bsddb
module: gdbm
module: dbm
module: dumbdbm
:mod:`anydbm` is a generic interface to variants of the DBM database ---
:mod:`dbhash` (requires :mod:`bsddb`), :mod:`gdbm`, or :mod:`dbm`. If none of
these modules is installed, the slow-but-simple implementation in module
:mod:`dumbdbm` will be used.
.. function:: open(filename[, flag[, mode]])
Open the database file *filename* and return a corresponding object.
If the database file already exists, the :mod:`whichdb` module is used to
determine its type and the appropriate module is used; if it does not exist, the
first module listed above that can be imported is used.
The optional *flag* argument can be ``'r'`` to open an existing database for
reading only, ``'w'`` to open an existing database for reading and writing,
``'c'`` to create the database if it doesn't exist, or ``'n'``, which will
always create a new empty database. If not specified, the default value is
``'r'``.
The optional *mode* argument is the Unix mode of the file, used only when the
database has to be created. It defaults to octal ``0666`` (and will be modified
by the prevailing umask).
.. exception:: error
A tuple containing the exceptions that can be raised by each of the supported
modules, with a unique exception also named :exc:`anydbm.error` as the first
item --- the latter is used when :exc:`anydbm.error` is raised.
The object returned by :func:`open` supports most of the same functionality as
dictionaries; keys and their corresponding values can be stored, retrieved, and
deleted, and the :meth:`has_key` and :meth:`keys` methods are available. Keys
and values must always be strings.
The following example records some hostnames and a corresponding title, and
then prints out the contents of the database::
import anydbm
# Open database, creating it if necessary.
db = anydbm.open('cache', 'c')
# Record some values
db['www.python.org'] = 'Python Website'
db['www.cnn.com'] = 'Cable News Network'
# Loop through contents. Other dictionary methods
# such as .keys(), .values() also work.
for k, v in db.iteritems():
print(k, '\t', v)
# Storing a non-string key or value will raise an exception (most
# likely a TypeError).
db['www.yahoo.com'] = 4
# Close when done.
db.close()

:mod:`dbhash` --- DBM-style interface to the BSD database library
=================================================================
.. module:: dbhash
:synopsis: DBM-style interface to the BSD database library.
.. sectionauthor:: Fred L. Drake, Jr. <fdrake@acm.org>
.. index:: module: bsddb
The :mod:`dbhash` module provides a function to open databases using the BSD
``db`` library. This module mirrors the interface of the other Python database
modules that provide access to DBM-style databases. The :mod:`bsddb` module is
required to use :mod:`dbhash`.
This module provides an exception and a function:
.. exception:: error
Exception raised on database errors other than :exc:`KeyError`. It is a synonym
for :exc:`bsddb.error`.
.. function:: open(path[, flag[, mode]])
Open a ``db`` database and return the database object. The *path* argument is
the name of the database file.
The *flag* argument can be:
+---------+-------------------------------------------+
| Value | Meaning |
+=========+===========================================+
| ``'r'`` | Open existing database for reading only |
| | (default) |
+---------+-------------------------------------------+
| ``'w'`` | Open existing database for reading and |
| | writing |
+---------+-------------------------------------------+
| ``'c'`` | Open database for reading and writing, |
| | creating it if it doesn't exist |
+---------+-------------------------------------------+
| ``'n'`` | Always create a new, empty database, open |
| | for reading and writing |
+---------+-------------------------------------------+
For platforms on which the BSD ``db`` library supports locking, an ``'l'``
can be appended to indicate that locking should be used.
The optional *mode* parameter is used to indicate the Unix permission bits that
should be set if a new database must be created; this will be masked by the
current umask value for the process.

.. _dbhash-objects:
Database Objects
----------------
The database objects returned by :func:`open` provide the methods common to all
the DBM-style databases and mapping objects. The following methods are
available in addition to the standard methods.
.. method:: dbhash.first()
It's possible to loop over every key/value pair in the database using this
method and the :meth:`next` method. The traversal is ordered by the databases
internal hash values, and won't be sorted by the key values. This method
returns the starting key.
.. method:: dbhash.last()
Return the last key/value pair in a database traversal. This may be used to
begin a reverse-order traversal; see :meth:`previous`.
.. method:: dbhash.next()
Returns the key next key/value pair in a database traversal. The following code
prints every key in the database ``db``, without having to create a list in
memory that contains them all::
print(db.first())
for i in range(1, len(db)):
print(db.next())
.. method:: dbhash.previous()
Returns the previous key/value pair in a forward-traversal of the database. In
conjunction with :meth:`last`, this may be used to implement a reverse-order
traversal.
.. method:: dbhash.sync()
This method forces any unwritten data to be written to the disk.

:mod:`dumbdbm` --- Portable DBM implementation
==============================================
.. module:: dumbdbm
:synopsis: Portable implementation of the simple DBM interface.
.. index:: single: databases
.. note::
The :mod:`dumbdbm` module is intended as a last resort fallback for the
:mod:`anydbm` module when no more robust module is available. The :mod:`dumbdbm`
module is not written for speed and is not nearly as heavily used as the other
database modules.
The :mod:`dumbdbm` module provides a persistent dictionary-like interface which
is written entirely in Python. Unlike other modules such as :mod:`gdbm` and
:mod:`bsddb`, no external library is required. As with other persistent
mappings, the keys and values must always be strings.
The module defines the following:
.. exception:: error
Raised on dumbdbm-specific errors, such as I/O errors. :exc:`KeyError` is
raised for general mapping errors like specifying an incorrect key.
.. function:: open(filename[, flag[, mode]])
Open a dumbdbm database and return a dumbdbm object. The *filename* argument is
the basename of the database file (without any specific extensions). When a
dumbdbm database is created, files with :file:`.dat` and :file:`.dir` extensions
are created.
The optional *flag* argument is currently ignored; the database is always opened
for update, and will be created if it does not exist.
The optional *mode* argument is the Unix mode of the file, used only when the
database has to be created. It defaults to octal ``0666`` (and will be modified
by the prevailing umask).
.. seealso::

Dumbdbm Objects
---------------
In addition to the methods provided by the :class:`UserDict.DictMixin` class,
:class:`dumbdbm` objects provide the following methods.
.. method:: dumbdbm.sync()
Synchronize the on-disk directory and data files. This method is called by the
:meth:`sync` method of :class:`Shelve` objects.

:mod:`gdbm` --- GNU's reinterpretation of dbm
=============================================
.. module:: gdbm
:platform: Unix
:synopsis: GNU's reinterpretation of dbm.
.. index:: module: dbm
This module is quite similar to the :mod:`dbm` module, but uses ``gdbm`` instead
to provide some additional functionality. Please note that the file formats
created by ``gdbm`` and ``dbm`` are incompatible.
The :mod:`gdbm` module provides an interface to the GNU DBM library. ``gdbm``
objects behave like mappings (dictionaries), except that keys and values are
always strings. Printing a ``gdbm`` object doesn't print the keys and values,
and the :meth:`items` and :meth:`values` methods are not supported.
The module defines the following constant and functions:
.. exception:: error
Raised on ``gdbm``\ -specific errors, such as I/O errors. :exc:`KeyError` is
raised for general mapping errors like specifying an incorrect key.
.. function:: open(filename, [flag, [mode]])
Open a ``gdbm`` database and return a ``gdbm`` object. The *filename* argument
is the name of the database file.
The optional *flag* argument can be:
+---------+-------------------------------------------+
| Value | Meaning |
+=========+===========================================+
| ``'r'`` | Open existing database for reading only |
| | (default) |
+---------+-------------------------------------------+
| ``'w'`` | Open existing database for reading and |
| | writing |
+---------+-------------------------------------------+
| ``'c'`` | Open database for reading and writing, |
| | creating it if it doesn't exist |
+---------+-------------------------------------------+
| ``'n'`` | Always create a new, empty database, open |
| | for reading and writing |
+---------+-------------------------------------------+
The following additional characters may be appended to the flag to control
how the database is opened:
+---------+--------------------------------------------+
| Value | Meaning |
+=========+============================================+
| ``'f'`` | Open the database in fast mode. Writes |
| | to the database will not be synchronized. |
+---------+--------------------------------------------+
| ``'s'`` | Synchronized mode. This will cause changes |
| | to the database to be immediately written |
| | to the file. |
+---------+--------------------------------------------+
| ``'u'`` | Do not lock database. |
+---------+--------------------------------------------+
Not all flags are valid for all versions of ``gdbm``. The module constant
:const:`open_flags` is a string of supported flag characters. The exception
:exc:`error` is raised if an invalid flag is specified.
The optional *mode* argument is the Unix mode of the file, used only when the
database has to be created. It defaults to octal ``0666``.
In addition to the dictionary-like methods, ``gdbm`` objects have the following
methods:
.. function:: firstkey()
It's possible to loop over every key in the database using this method and the
:meth:`nextkey` method. The traversal is ordered by ``gdbm``'s internal hash
values, and won't be sorted by the key values. This method returns the starting
key.
.. function:: nextkey(key)
Returns the key that follows *key* in the traversal. The following code prints
every key in the database ``db``, without having to create a list in memory that
contains them all::
k = db.firstkey()
while k != None:
print(k)
k = db.nextkey(k)
.. function:: reorganize()
If you have carried out a lot of deletions and would like to shrink the space
used by the ``gdbm`` file, this routine will reorganize the database. ``gdbm``
will not shorten the length of a database file except by using this
reorganization; otherwise, deleted file space will be kept and reused as new
(key, value) pairs are added.
.. function:: sync()
When the database has been opened in fast mode, this method forces any
unwritten data to be written to the disk.
