Note that archaic use of type(x) == types.DictType is because of keeping 1.5.2 compatibility. While this is much less relevant these days, there probably needs to be a separate commit for removing all archaic constructs at the same time. ........ r58288 | brett.cannon | 2007-09-30 12:45:10 -0700 (Sun, 30 Sep 2007) | 9 lines tuple.__repr__ did not consider a reference loop as it is not possible from Python code; but it is possible from C. object.__str__ had the issue of not expecting a type to doing something within it's tp_str implementation that could trigger an infinite recursion, but it could in C code.. Both found thanks to BaseException and how it handles its repr. Closes issue #1686386. Thanks to Thomas Herve for taking an initial stab at coming up with a solution. ........ r58289 | brett.cannon | 2007-09-30 13:37:19 -0700 (Sun, 30 Sep 2007) | 3 lines Fix error introduced by r58288; if a tuple is length 0 return its repr and don't worry about any self-referring tuples. ........ r58294 | facundo.batista | 2007-10-02 10:01:24 -0700 (Tue, 02 Oct 2007) | 11 lines Made the various is_* operations return booleans. This was discussed with Cawlishaw by mail, and he basically confirmed that to these is_* operations, there's no need to return Decimal(0) and Decimal(1) if the language supports the False and True booleans. Also added a few tests for the these functions in extra.decTest, since they are mostly untested (apart from the doctests). Thanks Mark Dickinson ........ r58295 | facundo.batista | 2007-10-02 11:21:18 -0700 (Tue, 02 Oct 2007) | 4 lines Added a class to store the digits of log(10), so that they can be made available when necessary without recomputing.

+ * 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 BerkeleyDB 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@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@krypto.org> is once again the maintainer.
+ *
+ * Use the pybsddb-users@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)
