Gregory P. Smith 19699a9351 Adds support for DB.pget and DBCursor.pget methods.
Based on a patch supplied by Ian Ward <ian@arevco.ca> on the pybsddb
mailing list 2004-03-26.

Gregory P. Smith 31c50659ea Add weakref support to all bsddb.db objects.
Make DBTxn objects automatically call abort() in their destructor if
not yet finalized and raise a RuntimeWarning to that effect.

Gregory P. Smith dc5af70631 SF patch / bug #967763
Fix memory leaks revealed by valgrind and ensuing code inspection.

In the existing test suite valgrind revealed two memory leaks (DB_get
and DBC_set_range).  Code inspection revealed that there were many other
potential similar leaks (many on odd code error paths such as passing
something other than a DBTxn object for a txn= parameter or in the face
of an out of memory error).  The most common case that would cause a
leak was when using recno or queue format databases with integer keys,
sometimes only with an exception exit.

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 7441e65821 * SF patch 835100 - C++ // comments are not allowed. Use /* */ 2003-11-03 21:35:31 +00:00
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 e276717113 Fix a tuple memory leak when raising DB, DBEnv and DBCursor "object
has been closed" exceptions.

Adds a DBCursorClosedError exception in the closed cursor case for
future use in fixing the legacy bsddb interface deadlock problems
due to its use of cursors with DB_INIT_LOCK | DB_THREAD support
enabled.

Gregory P. Smith be0db8b125 bsddb3 4.2.2, adds DBCursor.get_current_size() method to return the length
of the current value without reading the value itself.
2003-10-01 06:48:51 +00:00
Gregory P. Smith 7000225fbc raise pybsddb version number to 4.2.1 to differentiate between it and the
version in the python 2.3.1 tree.
2003-09-21 23:29:41 +00:00
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 6676f6edc1 Support DBEnv.set_shm_key() to allow multi-threaded multi-process
database environments to use shared memory on systems supporting it.

Martin v. Löwis 35c38eaeae heck environment closed status before closing a cursors. Fixes #763928. 2003-07-15 19:12:54 +00:00
Gregory P. Smith 455d46f0d9 bsddb 4.1.6:
* Extended DB & DBEnv set_get_returns_none functionality to take a
   "level" instead of a boolean flag.  The boolean 0 and 1 values still
   have the same effect.  A value of 2 extends the "return None instead
   of raising an exception" behaviour to the DBCursor set methods.
   This will become the default behaviour in pybsddb 4.2.
 * Fixed a typo in DBCursor.join_item method that made it crash instead
   of returning a value.  Obviously nobody uses it.  Wrote a test case
   for join and join_item.
2003-07-09 04:45:59 +00:00
Gregory P. Smith 84261d2f13 Fix a typo/cut-n-paste error in DBCursor.join_item so that it doesn't
return a tuple.  (this also implies that nobody uses this method; the
bug has been here for a long time)

Gregory P. Smith f655dff807 DB.remove() needs to set the internal DB handle to NULL after being called.
(sourceforge pybsddb bug #737970).

Also: don't allow other threads to run during calls that invalidate the
DB handle.

Mark Hammond a69d409f05 Update to the new PyGILState APIs to simplify and correct thread-state
management.  Old code still #ifdef'd out - I may remove this in a sec,
but for now, let's get it in and things passing the tests again!

Gregory P. Smith b6c9f78074 bugfix: do not double-close DB cursor during deallocation when the
underlying DB has already been closed (and thus all of its cursors).
        This fixes a potential segfault.
        SF pybsddb bug id 667343
bugfix: close the DB object when raising an exception due to an error
        during DB.open.  This prevents an exception when closing the
        environment about not all databases being closed.
