Gregory P. Smith 838c33268b backport of r57378 to fix bug 1725856 2007-08-24 05:26:15 +00:00
Gregory P. Smith 506f7b559a - bsddb: multithreaded DB access using the simple bsddb module interface
now works reliably.  It has been updated to use automatic BerkeleyDB
  deadlock detection and the bsddb.dbutils.DeadlockWrap wrapper to retry
  database calls that would previously deadlock. [SF python bug #775414]

Gregory P. Smith 996710fd44 pasted set_lk_detect line in wrong spot in previous commit. fixed. passes tests this time. 2006-06-08 05:39:54 +00:00
Gregory P. Smith dda291c079 * Turn the deadlock situation described in SF bug #775414 into a
DBDeadLockError exception.
* add the test case for my previous dbtables commit.

Gregory P. Smith 64029986bc Fixes bug #1117761
bsddb.*open() methods cachesize parameter wouldn't work (raised an
internal bsddb.db exception when it was given).  The set_cachesize
call needed to be moved from the DB object to the DBEnv since the env
was introduced to allow for threading.

(will backport to 2.4)

Gregory P. Smith 14c6b4626f Closes bug #1149413
Using None for a filename with the 'n' flag when calling bsddb.btopen
would cause an error while checking if the file None existed.  error
not likely to be seen as anyone using None for a filename would likely
use the 'c' flag in the first place.

Georg Brandl 26caeba35a Bug #1396678: a closed bsddb.DB raises AttributeError on repr().
It now returns "{}". Is that the correct solution?

Martin v. Löwis e869eb1953 Patch #1112812: Make bsddb/__init__.py more friendly for modulefinder.
Backported to 2.4.

Gregory P. Smith a6b3caad41 Fix SF bug # 897820 - we can no longer use the DB_TRUNCATE flag when
opening the DB to implement legacy interface flag='n' support as
BerkeleyDB 4.2.52 no longer allows it in transaction protected
environments.  Do the os.unlink ourselves.

Gregory P. Smith a7befda8d8 Fixes SF bug # 778421
* Fixed a bug in the compatibility interface set_location() method
   where it would not properly search to the next nearest key when
   used on BTree databases.  [SF bug id 788421]
 * Fixed a bug in the compatibility interface set_location() method
   where it could crash when looking up keys in a hash or recno
   format database due to an incorrect free().

Gregory P. Smith e33aef7b15 __init__.py: keep it compatible with older python (True and False == 1 and 0)
test_basics.py: updated for the set_get_returns_none() default of 2 change.

Gregory P. Smith a703a21b48 * Use weakref's of DBCursor objects for the iterator cursors to avoid a
memory leak that would've occurred for all iterators that were
  destroyed before having iterated until they raised StopIteration.

* Simplify some code.

* Add new test cases to check for the memleak and ensure that mixing
  iteration with modification of the values for existing keys works.

Gregory P. Smith dc113a8a06 * Fix the singlethreaded deadlocks occurring in the simple bsddb interface.
* Add support for multiple iterator/generator objects at once on the simple
  bsddb _DBWithCursor interface.

Gregory P. Smith 1eb41e22ab Use a threadsafe private DBEnv for each bsddb compatibility interface
db that is opened.  DB_THREAD and DB_INIT_LOCK allow for multithreaded
access.  DB_PRIVATE prevents the DBEnv from using the filesystem
(making it only usable by this process; and in this implementation
using one DBEnv per bsddb database)

Gregory P. Smith 41631e8f66 Adds basic support for BerkeleyDB 4.2.x. Compiles and passes tests; new
features in BerkeleyDB not exposed.  notably: the DB_MPOOLFILE interface
has not yet been wrapped in an object.

Adds support for building and installing bsddb3 in python2.3 that has
an older version of this module installed as bsddb without conflicts.
The pybsddb.sf.net build/packaged version of the module uses a
dynamicly loadable module called _pybsddb rather than _bsddb.

Gregory P. Smith cec1b3f6a7 Maintain backwards compatibility with python < 2.3 by dynamically
adding the iterator interface for python >= 2.3.

Raymond Hettinger 2e9da6020e The previous change works much faster (one lookup per key) when
iteritems() is defined.

Raymond Hettinger deadbf50e4 SF #662923
Add support for the iterator and mapping protocols.
For Py2.3, this was done for shelve, dumbdbm and other mapping objects, but
not for bsddb and dbhash which were inadvertently missed.

Barry Warsaw f71de3e9a0 Everything worked in both the distutils distro and in Python 2.3cvs,
so merge from the bsddb-bsddb3-schizo-branch back to the trunk.
2003-01-28 17:20:44 +00:00
Barry Warsaw 9a0d779c7d Port BerkeleyDB 4.1 support from the pybsddb project. bsddb is now at
version 4.1.1 and works with up to BerkeleyDB 4.1.25.
