* update_refs(): assert that incoming refcounts aren't 0. The commentTim Peters2003-11-141-0/+19
| | | | | | | | for this function has always claimed that was true, but it wasn't verified before. For the latest batch of "double deallocation" bugs (stemming from weakref callbacks invoked by way of subtype_dealloc), this assert would have triggered (instead of waiting for _Py_ForgetReference to die with a segfault later).
* Patch #804543: strdup saved locales. Backported to 2.3.Martin v. Löwis2003-11-131-1/+2

* Improve the implementation of itertools.tee().Raymond Hettinger2003-11-121-181/+199
| | | | | | | | | | | Formerly, underlying queue was implemented in terms of two lists. The new queue is a series of singly-linked fixed length lists. The new implementation runs much faster, supports multi-way tees, and allows tees of tees without additional memory costs. The root ideas for this structure were contributed by Andrew Koenig and Guido van Rossum.

* * Use weakref's of DBCursor objects for the iterator cursors to avoid aGregory P. Smith2003-11-031-2/+38
| | | | | | | | | | 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.
* * Fix the singlethreaded deadlocks occurring in the simple bsddb interface.Gregory P. Smith2003-11-021-1/+1
| | | | | * Add support for multiple iterator/generator objects at once on the simple bsddb _DBWithCursor interface.
* Fix a tuple memory leak when raising DB, DBEnv and DBCursor "objectGregory P. Smith2003-11-021-17/+15
| | | | | | | | | 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.

* Minor improvements to itertools.tee():Raymond Hettinger2003-10-261-9/+9
| | | | | | * tee object is no longer subclassable * independent iterators renamed to "itertools.tee_iterator" * fixed doc string typo and added entry in the module doc string
* Improvements to coding for itertools.tee():Raymond Hettinger2003-10-251-3/+26
| | | | | | | | | | | | * Add error checking code to PyList_Append() call. * Replace PyObject_CallMethod(to->outbasket, "pop", NULL) with equivalent in-line code. Inlining is important here because the search for the pop method will occur for every element returned by the iterator. * Make tee's dealloc() a little smarter. If the trailing iterator is being deallocated, then the queue data is no longer needed and can be freed.
* Added itertools.tee()Raymond Hettinger2003-10-241-0/+259
| | | | | | It works like the pure python verion except: * it stops storing data after of the iterators gets deallocated * the data queue is implemented with two stacks instead of one dictionary.
* - The pwd module incorrectly advertised its struct type asGuido van Rossum2003-10-231-0/+2

* Simplify and speedup uses of Py_BuildValue():Raymond Hettinger2003-10-1215-32/+29

* SF bug #812202: randint is always evenRaymond Hettinger2003-10-051-0/+44
| | | | | | | * Added C coded getrandbits(k) method that runs in linear time. * Call the new method from randrange() for ranges >= 2**53. * Adds a warning for generators not defining getrandbits() whenever they have a call to randrange() with too large of a population.

* Adds basic support for BerkeleyDB 4.2.x. Compiles and passes tests; newGregory P. Smith2003-09-211-5/+44
| | | | | | | | | | 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.
