Gregory P. Smith 7f5b6f4b33 Fix bsddb.db.DBError derived exceptions so they can be unpickled.
Also adds some backwards compatibility when compiling _bsddb.c on earlier
python versions (needed for pybsddb).

Thomas Wouters b2820ae355 Fix another leak in bsddb, and avoid use of uninitialized value -- funny how
gcc 4.0.x wasn't complaining about *that* one ;)
2006-03-12 00:01:38 +00:00
Thomas Wouters b3153832c2 Clean up _bsddb.c: add a couple dozen missing Py_DECREF()'s, a handful of
missing PyObject_Del()'s, simplify some code by using Py_BuildValue()
instead of creating a tuple with items manually, stop clobbering builtin
exceptions in a few places, and guard against NULL-returning functions some
more.

This fixes 117 of the 780 (!?!#%@#$!!) reference leaks in test_bsddb3. I
ain't not done yet, although this review of 5kloc was just the easy part.

Will backport.

Thomas Wouters 9d63ccae90 Fix DBEnv's set_tx_timestamp wrapper to be slightly more correct on
non-32bit platforms. Will still only allow 32 bits in a timestamp on Win64,
but at least it won't crash, and it'll work right on platforms where longs
are big enough to contain time_t's.

(A better-working, although conceptually less-right fix would have been to
use Py_ssize_t here, but Martin and Tim won't let me.)

Gregory P. Smith 4e414d8386 commits sourceforge patch #1407992 by neil.norwitz.
this fixes the bsddb db associate tests when compiled against
BerkeleyDB 3.3 thru 4.1.  4.2 thru 4.4 already passed and still
pass.
2006-01-24 19:55:02 +00:00
Gregory P. Smith 29602d2153 Support for BerkeleyDB 4.4 (tested against 4.4.20 as well as all the
way back thru 3.2).  This should be backported to the release24-maint
branch.

Neal Norwitz 40c6b47ca1 Fix errors on 64-bit platforms. Will backport 2006-01-05 05:43:35 +00:00
Jeremy Hylton af68c874a6 Add const to several API functions that take char *.
In C++, it's an error to pass a string literal to a char* function
without a const_cast().  Rather than require every C++ extension
module to put a cast around string literals, fix the API to state the
const-ness.

I focused on parts of the API where people usually pass literals:
PyArg_ParseTuple() and friends, Py_BuildValue(), PyMethodDef, the type
slots, etc.  Predictably, there were a large set of functions that
needed to be fixed as a result of these changes.  The most pervasive
change was to make the keyword args list passed to
PyArg_ParseTupleAndKewords() to be a const char *kwlist[].

One cast was required as a result of the changes:  A type object
mallocs the memory for its tp_doc slot and later frees it.
PyTypeObject says that tp_doc is const char *; but if the type was
created by type_new(), we know it is safe to cast to char *.

Gregory P. Smith 692ca9a0cb fixes pybsddb SF bug id 1215432. DB.associate() would crash when a
DBError was supposed to be raised.

Gregory P. Smith e947706b10 pybsddb 4.3.2:
* the has_key() method was not raising a DBError when a database error
   had occurred. [SF patch id 1212590]
 * added a wrapper for the DBEnv.set_lg_regionmax method [SF patch id 1212590]
 * DBKeyEmptyError now derives from KeyError just like DBNotFoundError.
 * internally everywhere DB_NOTFOUND was checked for has been updated
   to also check for DB_KEYEMPTY.  This fixes the semantics of a couple
   operations on recno and queue databases to be more intuitive and results
   in less unexpected DBKeyEmptyError exceptions being raised.

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 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 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

Gregory P. Smith 7000225fbc raise pybsddb version number to 4.2.1 to differentiate between it and the

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.

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.
