-:mod:`bsddb` --- Interface to Berkeley DB library
-=================================================
-
-.. module:: bsddb
- :synopsis: Interface to Berkeley DB database library
-.. sectionauthor:: Skip Montanaro <skip at pobox.com>
-
-
-The :mod:`bsddb` module provides an interface to the Berkeley DB library. Users
-can create hash, btree or record based library files using the appropriate open
-call. Bsddb objects behave generally like dictionaries. Keys and values must be
-strings, however, so to use other objects as keys or to store other kinds of
-objects the user must serialize them somehow, typically using
-:func:`marshal.dumps` or :func:`pickle.dumps`.
-
-The :mod:`bsddb` module requires a Berkeley DB library version from 3.3 thru
-4.5.
-
-
-.. seealso::
-
- http://pybsddb.sourceforge.net/
- The website with documentation for the :mod:`bsddb.db` Python Berkeley DB
- interface that closely mirrors the object oriented interface provided in
- Berkeley DB 3 and 4.
-
- http://www.oracle.com/database/berkeley-db/
- The Berkeley DB library.
-
-A more modern DB, DBEnv and DBSequence object interface is available in the
-:mod:`bsddb.db` module which closely matches the Berkeley DB C API documented at
-the above URLs. Additional features provided by the :mod:`bsddb.db` API include
-fine tuning, transactions, logging, and multiprocess concurrent database access.
-
-The following is a description of the legacy :mod:`bsddb` interface compatible
-with the old Python bsddb module. Starting in Python 2.5 this interface should
-be safe for multithreaded access. The :mod:`bsddb.db` API is recommended for
-threading users as it provides better control.
-
-The :mod:`bsddb` module defines the following functions that create objects that
-access the appropriate type of Berkeley DB file. The first two arguments of
-each function are the same. For ease of portability, only the first two
-arguments should be used in most instances.
-
-
-.. function:: hashopen(filename[, flag[, mode[, pgsize[, ffactor[, nelem[, cachesize[, lorder[, hflags]]]]]]]])
-
- Open the hash format file named *filename*. Files never intended to be
- preserved on disk may be created by passing ``None`` as the *filename*. The
- optional *flag* identifies the mode used to open the file. It may be ``'r'``
- (read only), ``'w'`` (read-write) , ``'c'`` (read-write - create if necessary;
- the default) or ``'n'`` (read-write - truncate to zero length). The other
- arguments are rarely used and are just passed to the low-level :cfunc:`dbopen`
- function. Consult the Berkeley DB documentation for their use and
- interpretation.
-
-
-.. function:: btopen(filename[, flag[, mode[, btflags[, cachesize[, maxkeypage[, minkeypage[, pgsize[, lorder]]]]]]]])
-
- Open the btree format file named *filename*. Files never intended to be
- preserved on disk may be created by passing ``None`` as the *filename*. The
- optional *flag* identifies the mode used to open the file. It may be ``'r'``
- (read only), ``'w'`` (read-write), ``'c'`` (read-write - create if necessary;
- the default) or ``'n'`` (read-write - truncate to zero length). The other
- arguments are rarely used and are just passed to the low-level dbopen function.
- Consult the Berkeley DB documentation for their use and interpretation.
-
-
-.. function:: rnopen(filename[, flag[, mode[, rnflags[, cachesize[, pgsize[, lorder[, rlen[, delim[, source[, pad]]]]]]]]]])
-
- Open a DB record format file named *filename*. Files never intended to be
- preserved on disk may be created by passing ``None`` as the *filename*. The
- optional *flag* identifies the mode used to open the file. It may be ``'r'``
- (read only), ``'w'`` (read-write), ``'c'`` (read-write - create if necessary;
- the default) or ``'n'`` (read-write - truncate to zero length). The other
- arguments are rarely used and are just passed to the low-level dbopen function.
- Consult the Berkeley DB documentation for their use and interpretation.
-
-
-.. class:: StringKeys(db)
-
- Wrapper class around a DB object that supports string keys (rather than bytes).
- All keys are encoded as UTF-8, then passed to the underlying object.
-
-
-.. class:: StringValues(db)
-
- Wrapper class around a DB object that supports string values (rather than bytes).
- All values are encoded as UTF-8, then passed to the underlying object.
-
-
-.. seealso::
-
- Module :mod:`dbm.bsd`
- DBM-style interface to the :mod:`bsddb`
-
-
-.. _bsddb-objects:
-
-Hash, BTree and Record Objects
-------------------------------
-
-Once instantiated, hash, btree and record objects support the same methods as
-dictionaries. In addition, they support the methods listed below.
-
-
-.. describe:: key in bsddbobject
-
- Return ``True`` if the DB file contains the argument as a key.
-
-
-.. method:: bsddbobject.close()
-
- Close the underlying file. The object can no longer be accessed. Since there
- is no open :meth:`open` method for these objects, to open the file again a new
- :mod:`bsddb` module open function must be called.
-
-
-.. method:: bsddbobject.keys()
-
- Return the list of keys contained in the DB file. The order of the list is
- unspecified and should not be relied on. In particular, the order of the list
- returned is different for different file formats.
-
-
-.. method:: bsddbobject.set_location(key)
-
- Set the cursor to the item indicated by *key* and return a tuple containing the
- key and its value. For binary tree databases (opened using :func:`btopen`), if
- *key* does not actually exist in the database, the cursor will point to the next
- item in sorted order and return that key and value. For other databases,
- :exc:`KeyError` will be raised if *key* is not found in the database.
-
-
-.. method:: bsddbobject.first()
-
- Set the cursor to the first item in the DB file and return it. The order of
- keys in the file is unspecified, except in the case of B-Tree databases. This
- method raises :exc:`bsddb.error` if the database is empty.
-
-
-.. method:: bsddbobject.next()
-
- Set the cursor to the next item in the DB file and return it. The order of
- keys in the file is unspecified, except in the case of B-Tree databases.
-
-
-.. method:: bsddbobject.previous()
-
- Set the cursor to the previous item in the DB file and return it. The order of
- keys in the file is unspecified, except in the case of B-Tree databases. This
- is not supported on hashtable databases (those opened with :func:`hashopen`).
-
-
-.. method:: bsddbobject.last()
-
- Set the cursor to the last item in the DB file and return it. The order of keys
- in the file is unspecified. This is not supported on hashtable databases (those
- opened with :func:`hashopen`). This method raises :exc:`bsddb.error` if the
- database is empty.
-
-
-.. method:: bsddbobject.sync()
-
- Synchronize the database on disk.
-
-Example::
-
- >>> import bsddb
- >>> db = bsddb.btopen('/tmp/spam.db', 'c')
- >>> for i in range(10):
- ... db[str(i)] = '%d' % (i*i)
- ...
- >>> db['3']
- '9'
- >>> db.keys()
- ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
- >>> db.first()
- ('0', '0')
- >>> db.next()
- ('1', '1')
- >>> db.last()
- ('9', '81')
- >>> db.set_location('2')
- ('2', '4')
- >>> db.previous()
- ('1', '1')
- >>> for k, v in db.iteritems():
- ... print(k, v)
- 0 0
- 1 1
- 2 4
- 3 9
- 4 16
- 5 25
- 6 36
- 7 49
- 8 64
- 9 81
- >>> '8' in db
- True
- >>> db.sync()
- 0

- * Handwritten code to wrap version 3.x of the Berkeley DB library,
- * written to replace a SWIG-generated file. It has since been updated
- * to compile with Berkeley DB versions 3.2 through 4.2.
- *
- * This module was started by Andrew Kuchling to remove the dependency
- * on SWIG in a package by Gregory P. Smith who based his work on a
- * similar package by Robin Dunn <robin at alldunn.com> which wrapped
- * Berkeley DB 2.7.x.
- *
- * Development of this module then returned full circle back to Robin Dunn
- * who worked on behalf of Digital Creations to complete the wrapping of
- * the DB 3.x API and to build a solid unit test suite. Robin has
- * since gone onto other projects (wxPython).
- *
- * Gregory P. Smith <greg at krypto.org> was once again the maintainer.
- *
- * Since January 2008, new maintainer is Jesus Cea <jcea at jcea.es>.
- * Jesus Cea licenses this code to PSF under a Contributor Agreement.
- *
- * Use the pybsddb-users at lists.sf.net mailing list for all questions.
- * Things can change faster than the header of this file is updated. This
- * file is shared with the PyBSDDB project at SourceForge:
- *
- * http://pybsddb.sf.net
- *
- * This file should remain backward compatible with Python 2.1, but see PEP
- * 291 for the most current backward compatibility requirements:
- *
- * http://www.python.org/peps/pep-0291.html
- *
- * This module contains 6 types:
- *
- * DB (Database)
- * DBCursor (Database Cursor)
- * DBEnv (database environment)
- * DBTxn (An explicit database transaction)
- * DBLock (A lock handle)
- * DBSequence (Sequence)
- *

- * Portions of this module, associated unit tests and build scripts are the

- * Handwritten code to wrap version 3.x of the Berkeley DB library,
- * written to replace a SWIG-generated file. It has since been updated
- * to compile with Berkeley DB versions 3.2 through 4.2.
- *
- * This module was started by Andrew Kuchling to remove the dependency
- * on SWIG in a package by Gregory P. Smith who based his work on a
- * similar package by Robin Dunn <robin at alldunn.com> which wrapped
- * Berkeley DB 2.7.x.
- *
- * Development of this module then returned full circle back to Robin Dunn
- * who worked on behalf of Digital Creations to complete the wrapping of
- * the DB 3.x API and to build a solid unit test suite. Robin has
- * since gone onto other projects (wxPython).
- *
- * Gregory P. Smith <greg at krypto.org> is once again the maintainer.
- *
- * Use the pybsddb-users at lists.sf.net mailing list for all questions.
- * Things can change faster than the header of this file is updated. This
- * file is shared with the PyBSDDB project at SourceForge:
- *
- * http://pybsddb.sf.net
- *
- * This file should remain backward compatible with Python 2.1, but see PEP
- * 291 for the most current backward compatibility requirements:
- *
- * http://www.python.org/peps/pep-0291.html
- *
- * This module contains 6 types:
- *
- * DB (Database)
- * DBCursor (Database Cursor)
- * DBEnv (database environment)
- * DBTxn (An explicit database transaction)
- * DBLock (A lock handle)
- * DBSequence (Sequence)

-:mod:`bsddb` --- Interface to Berkeley DB library
-=================================================
-
-.. module:: bsddb
- :synopsis: Interface to Berkeley DB database library
-.. sectionauthor:: Skip Montanaro <skip at pobox.com>
-
-
-The :mod:`bsddb` module provides an interface to the Berkeley DB library. Users
-can create hash, btree or record based library files using the appropriate open
-call. Bsddb objects behave generally like dictionaries. Keys and values must be
-strings, however, so to use other objects as keys or to store other kinds of
-objects the user must serialize them somehow, typically using
-:func:`marshal.dumps` or :func:`pickle.dumps`.
-
-The :mod:`bsddb` module requires a Berkeley DB library version from 3.3 thru
-4.5.
-
-
-.. seealso::
-
- http://pybsddb.sourceforge.net/
- The website with documentation for the :mod:`bsddb.db` Python Berkeley DB
- interface that closely mirrors the object oriented interface provided in
- Berkeley DB 3 and 4.
-
- http://www.oracle.com/database/berkeley-db/
- The Berkeley DB library.
-
-A more modern DB, DBEnv and DBSequence object interface is available in the
-:mod:`bsddb.db` module which closely matches the Berkeley DB C API documented at
-the above URLs. Additional features provided by the :mod:`bsddb.db` API include
-fine tuning, transactions, logging, and multiprocess concurrent database access.
-
-The following is a description of the legacy :mod:`bsddb` interface compatible
-with the old Python bsddb module. Starting in Python 2.5 this interface should
-be safe for multithreaded access. The :mod:`bsddb.db` API is recommended for
-threading users as it provides better control.
-
-The :mod:`bsddb` module defines the following functions that create objects that
-access the appropriate type of Berkeley DB file. The first two arguments of
-each function are the same. For ease of portability, only the first two
-arguments should be used in most instances.
-
-
-.. function:: hashopen(filename[, flag[, mode[, pgsize[, ffactor[, nelem[, cachesize[, lorder[, hflags]]]]]]]])
-
- Open the hash format file named *filename*. Files never intended to be
- preserved on disk may be created by passing ``None`` as the *filename*. The
- optional *flag* identifies the mode used to open the file. It may be ``'r'``
- (read only), ``'w'`` (read-write) , ``'c'`` (read-write - create if necessary;
- the default) or ``'n'`` (read-write - truncate to zero length). The other
- arguments are rarely used and are just passed to the low-level :cfunc:`dbopen`
- function. Consult the Berkeley DB documentation for their use and
- interpretation.
-
-
-.. function:: btopen(filename[, flag[, mode[, btflags[, cachesize[, maxkeypage[, minkeypage[, pgsize[, lorder]]]]]]]])
-
- Open the btree format file named *filename*. Files never intended to be
- preserved on disk may be created by passing ``None`` as the *filename*. The
- optional *flag* identifies the mode used to open the file. It may be ``'r'``
- (read only), ``'w'`` (read-write), ``'c'`` (read-write - create if necessary;
- the default) or ``'n'`` (read-write - truncate to zero length). The other
- arguments are rarely used and are just passed to the low-level dbopen function.
- Consult the Berkeley DB documentation for their use and interpretation.
-
-
-.. function:: rnopen(filename[, flag[, mode[, rnflags[, cachesize[, pgsize[, lorder[, rlen[, delim[, source[, pad]]]]]]]]]])
-
- Open a DB record format file named *filename*. Files never intended to be
- preserved on disk may be created by passing ``None`` as the *filename*. The
- optional *flag* identifies the mode used to open the file. It may be ``'r'``
- (read only), ``'w'`` (read-write), ``'c'`` (read-write - create if necessary;
- the default) or ``'n'`` (read-write - truncate to zero length). The other
- arguments are rarely used and are just passed to the low-level dbopen function.
- Consult the Berkeley DB documentation for their use and interpretation.
-
-
-.. class:: StringKeys(db)
-
- Wrapper class around a DB object that supports string keys (rather than bytes).
- All keys are encoded as UTF-8, then passed to the underlying object.
-
-
-.. class:: StringValues(db)
-
- Wrapper class around a DB object that supports string values (rather than bytes).
- All values are encoded as UTF-8, then passed to the underlying object.

- Module :mod:`dbm.bsd`

-.. _bsddb-objects:
-
-Hash, BTree and Record Objects
-------------------------------
-
-Once instantiated, hash, btree and record objects support the same methods as
-dictionaries. In addition, they support the methods listed below.
-
-
-.. describe:: key in bsddbobject
-
- Return ``True`` if the DB file contains the argument as a key.
-
-
-.. method:: bsddbobject.close()
-
- Close the underlying file. The object can no longer be accessed. Since there
- is no open :meth:`open` method for these objects, to open the file again a new
- :mod:`bsddb` module open function must be called.
-
-
-.. method:: bsddbobject.keys()
-
- Return the list of keys contained in the DB file. The order of the list is
- unspecified and should not be relied on. In particular, the order of the list
- returned is different for different file formats.
-
-
-.. method:: bsddbobject.set_location(key)
-
- Set the cursor to the item indicated by *key* and return a tuple containing the
- key and its value. For binary tree databases (opened using :func:`btopen`), if
- *key* does not actually exist in the database, the cursor will point to the next
- item in sorted order and return that key and value. For other databases,
- :exc:`KeyError` will be raised if *key* is not found in the database.
-
-
-.. method:: bsddbobject.first()
-
- Set the cursor to the first item in the DB file and return it. The order of
- keys in the file is unspecified, except in the case of B-Tree databases. This
- method raises :exc:`bsddb.error` if the database is empty.
-
-
-.. method:: bsddbobject.next()
-
- Set the cursor to the next item in the DB file and return it. The order of
- keys in the file is unspecified, except in the case of B-Tree databases.
-
-
-.. method:: bsddbobject.previous()
-
- Set the cursor to the previous item in the DB file and return it. The order of
- keys in the file is unspecified, except in the case of B-Tree databases. This
- is not supported on hashtable databases (those opened with :func:`hashopen`).
-
-
-.. method:: bsddbobject.last()
-
- Set the cursor to the last item in the DB file and return it. The order of keys
- in the file is unspecified. This is not supported on hashtable databases (those
- opened with :func:`hashopen`). This method raises :exc:`bsddb.error` if the
- database is empty.
-
-
-.. method:: bsddbobject.sync()
-
- Synchronize the database on disk.
-
-Example::
-
- >>> import bsddb
- >>> db = bsddb.btopen('/tmp/spam.db', 'c')
- >>> for i in range(10):
- ... db[str(i)] = '%d' % (i*i)
- ...
- >>> db['3']
- '9'
- >>> db.keys()
- ['0', '1', '2', '3', '4', '5', '6', '7', '8', '9']
- >>> db.first()
- ('0', '0')
- >>> db.next()
- ('1', '1')
- >>> db.last()
- ('9', '81')
- >>> db.set_location('2')
- ('2', '4')
- >>> db.previous()
- ('1', '1')
- >>> for k, v in db.iteritems():
- ... print(k, v)
- 0 0
- 1 1
- 2 4
- 3 9
- 4 16
- 5 25

- * Handwritten code to wrap version 3.x of the Berkeley DB library,

- * This module was started by Andrew Kuchling to remove the dependency
- * on SWIG in a package by Gregory P. Smith who based his work on a
- * similar package by Robin Dunn <robin at alldunn.com> which wrapped
- * Berkeley DB 2.7.x.
- *
- * Development of this module then returned full circle back to Robin Dunn
- * who worked on behalf of Digital Creations to complete the wrapping of
- * the DB 3.x API and to build a solid unit test suite. Robin has
- * since gone onto other projects (wxPython).
- *
- * Gregory P. Smith <greg at krypto.org> was once again the maintainer.
- *
- * Since January 2008, new maintainer is Jesus Cea <jcea at jcea.es>.
- * Jesus Cea licenses this code to PSF under a Contributor Agreement.
- *
- * Use the pybsddb-users at lists.sf.net mailing list for all questions.
- * Things can change faster than the header of this file is updated. This
- * file is shared with the PyBSDDB project at SourceForge:

- * This file should remain backward compatible with Python 2.1, but see PEP
- * 291 for the most current backward compatibility requirements:

- * This module contains 6 types:
- *

- * DBCursor (Database Cursor)
- * DBEnv (database environment)
- * DBTxn (An explicit database transaction)
- * DBLock (A lock handle)
- * DBSequence (Sequence)

- * Handwritten code to wrap version 3.x of the Berkeley DB library,
- * written to replace a SWIG-generated file. It has since been updated
- * to compile with Berkeley DB versions 3.2 through 4.2.
- *
- * This module was started by Andrew Kuchling to remove the dependency
- * on SWIG in a package by Gregory P. Smith who based his work on a
- * similar package by Robin Dunn <robin at alldunn.com> which wrapped
- * Berkeley DB 2.7.x.
- *
- * Development of this module then returned full circle back to Robin Dunn
- * who worked on behalf of Digital Creations to complete the wrapping of
- * the DB 3.x API and to build a solid unit test suite. Robin has
- * since gone onto other projects (wxPython).
- *
- * Gregory P. Smith <greg at krypto.org> is once again the maintainer.
- *
- * Use the pybsddb-users at lists.sf.net mailing list for all questions.
- * Things can change faster than the header of this file is updated. This
- * file is shared with the PyBSDDB project at SourceForge:
- *
- * http://pybsddb.sf.net
- *
- * This file should remain backward compatible with Python 2.1, but see PEP
- * 291 for the most current backward compatibility requirements:
- *
- * http://www.python.org/peps/pep-0291.html
- *
- * This module contains 6 types:
- *
- * DB (Database)
- * DBCursor (Database Cursor)
- * DBEnv (database environment)
- * DBTxn (An explicit database transaction)
- * DBLock (A lock handle)
- * DBSequence (Sequence)
- *

-
-/*
- * Portions of this module, associated unit tests and build scripts are the
- * result of a contract with The Written Word (http://thewrittenword.com/)
- * Many thanks go out to them for causing me to raise the bar on quality and
