* Remove a function no longer in use.Raymond Hettinger2004-06-141-8/+0

* Remove unnecessary GC support. Sets cannot have cycles.Raymond Hettinger2004-06-131-16/+7
|
* * Factor out PyObject_SelfIter().Raymond Hettinger2004-06-121-9/+3
| | | | * Change a XDECREF to DECREF (adding an assertion just to be sure).
* Fix for bug #966623 - classes created with type() in an exec(, {}) don'tAnthony Baxter2004-06-111-0/+4
| | | | | | have a __module__. Test for this case. Bugfix candidate, will backport.
* dump HAVE_FOPENRF stuff - obsoleteSkip Montanaro2004-06-111-26/+19

* Futher improvements to frozenset hashing (based on Yitz Gale's battery ofRaymond Hettinger2004-06-101-8/+10
| | | | | | | | | | | | | tests which nicely highly highlight weaknesses). * Initial value is now a large prime. * Pre-multiply by the set length to add one more basis of differentiation. * Work a bit harder inside the loop to scatter bits from sources that may have closely spaced hash values. All of this is necessary to make up for keep the hash function commutative. Fortunately, the hash value is cached so the call to frozenset_hash() will only occur once per set.
* Fixups to the hash function for frozensets.Raymond Hettinger2004-06-101-1/+4
| | | | | | * Non-zero initial value so that hash(frozenset()) != hash(0). * Final permutation to differentiate nested sets. * Add logic to make sure that -1 is not a possible hash value.
* Add a final permutation step to the tuple hash function.Raymond Hettinger2004-06-101-0/+1
| | | | | Prevents a collision pattern that occurs with nested tuples. (Yitz Gale provided code that repeatably demonstrated the weakness.)

* SF bug #942952: Weakness in tuple hashRaymond Hettinger2004-06-011-2/+3
| | | | | | | (Basic approach and test concept by Tim Peters.) * Improved the hash to reduce collisions. * Added the torture test to the test suite.

* SF bug #952866: "can't multiply sequence *by* non-int"Raymond Hettinger2004-05-121-1/+1
| | | | Minor wording fix.
* Nits:Raymond Hettinger2004-05-051-16/+9
| | | | | | | - Neatened the braces in PyList_New(). - Made sure "indexerr" was initialized to NULL. - Factored if blocks in PyList_Append(). - Made sure "allocated" is initialized in list_init().
* SF patch #947476: Apply freelist technique to listsRaymond Hettinger2004-05-051-4/+17
| | | | | Re-use list object bodies. Saves calls to malloc() and free() for faster list instantiation and deallocation.
* Two new public API functions, Py_IncRef and Py_DecRef. Useful forThomas Heller2004-04-221-0/+12

* * Add unittests for iterators that report their lengthRaymond Hettinger2004-04-123-10/+29
| | | | | | * Document the differences between them * Fix corner cases covered by the unittests * Use Py_RETURN_NONE where possible for dictionaries
* Use Py_RETURN_NONE macro where applicable.Raymond Hettinger2004-04-121-14/+8

* Small refactoring saving one function() and eliminating some indirection.Raymond Hettinger2004-04-121-11/+10
| | | | | * Applied app1() to listappend(). * Inlined ins() into its one remaining caller.
* * Specialize ins1() into app1() for appends. Saves several unnecessaryRaymond Hettinger2004-04-121-6/+36

* If a file is opened with an explicit buffer size >= 1, repeatedAndrew MacIntyre2004-04-041-0/+2
| | | | | | | | close() calls would attempt to free() the buffer already free()ed on the first close(). [bug introduced with patch #788249] Making sure that the buffer is free()ed in file object deallocation is a belt-n-braces bit of insurance against a memory leak.

* PyTuple_New(): vrbl i no longer referenced, so removed it (which killsTim Peters2004-03-211-1/+1

* This is the fastest I could get on Intel GCC. I kept the memset() in to clearArmin Rigo2004-03-211-4/+11
| | | | | | | | the newly created tuples, but tuples added in the freelist are now cleared in tupledealloc already (which is very cheap, because we are already Py_XDECREF'ing all elements anyway). Python should have a standard Py_ZAP macro like ZAP in pystate.c.
* Changed file.name to be the object passed as the 'name' argument to file()Nicholas Bastin2004-03-211-17/+21
