Tim Peters	ec8147ba55	Various clarifications based on feedback & questions over the years. (grafted from `23181bf411`)	13 years ago
Antoine Pitrou	9d95254bb7	Issue #18772 : fix the gdb plugin after the set implementation changes	13 years ago
Antoine Pitrou	91541931f5	Back out 5bd9db528aed (issue #18408 ). It caused unsolved buildbot failures.	13 years ago
Raymond Hettinger	bfc1e1a9cd	Add the same dummy type that is used in dictionaries.	13 years ago
Tim Peters	01e75a699d	Add line explaining the "%sort" test. (grafted from `1ea833ecaf`)	13 years ago
Raymond Hettinger	fcf3b500ba	Issue 18797: Remove unneeded refcount adjustments for dummy objects. It suffices to keep just one reference when the object is created.	13 years ago
Raymond Hettinger	5bb1b1dd6f	Hoist the global dummy lookup out of the inner loop for set_merge().	13 years ago
Raymond Hettinger	929cbac307	Remove a redundant hash table probe (this was artifact from an earlier draft of the patch).	13 years ago
Raymond Hettinger	ae9e616a00	Issue 18772: Restore set dummy object back to unicode and restore the identity checks in lookkey(). The Gdb prettyprint plugin depended on the dummy object being displayable. Other solutions besides a unicode object are possible. For now, get it back up and running. The identity checks in lookkey() need to be there to prevent the dummy object from leaking through Py_RichCompareBool() into user code in the rare circumstance where the dummy's hash value exactly matches the hash value of the actual key being looked up.	13 years ago
Raymond Hettinger	3c0a4f5def	Issue18771: Reduce the cost of hash collisions for set objects.	13 years ago
Raymond Hettinger	07351a0449	Remove the else-clause because the conditions are no longer mutually exclusive.	13 years ago
Raymond Hettinger	237b34b074	Use a known unique object for the dummy entry. This lets us run PyObject_RichCompareBool() without first needing to check whether the entry is a dummy.	13 years ago
Serhiy Storchaka	8fa8ee3970	Issue #18701 : Remove support of old CPython versions (<3.0) from C code.	13 years ago
Raymond Hettinger	8ad3919577	Hoist the global "dummy" lookup outside of the reinsertion loop.	13 years ago
Raymond Hettinger	b1b915c796	Issue 18719: Remove a false optimization Remove an unused early-out test from the critical path for dict and set lookups. When the strings already have matching lengths, kinds, and hashes, there is no additional information gained by checking the first characters (the probability of a mismatch is already known to be less than 1 in 2**64).	13 years ago
Antoine Pitrou	9ed5f27266	Issue #18722 : Remove uses of the "register" keyword in C code.	13 years ago
Raymond Hettinger	c629d4c9a2	Replace outdated optimization with clearer code that compiles better. Letting the compiler decide how to optimize the multiply by five gives it the freedom to make better choices for the best technique for a given target machine. For example, GCC on x86_64 produces a little bit better code: Old-way (3 steps with a data dependency between each step): shrq $5, %r13 leaq 1(%rbx,%r13), %rax leaq (%rax,%rbx,4), %rbx New-way (3 steps with no dependency between the first two steps which can be run in parallel): leaq (%rbx,%rbx,4), %rax # i5 shrq $5, %r13 # perturb >>= PERTURB_SHIFT leaq 1(%r13,%rax), %rbx # 1 + perturb + i5	13 years ago
Antoine Pitrou	58720d6145	Issue #17934 : Add a clear() method to frame objects, to help clean up expensive details (local variables) and break reference cycles.	13 years ago
Raymond Hettinger	c86d7e989c	Silence compiler warning for an unused declaration	13 years ago
Raymond Hettinger	e56666d17f	Silence compiler warning about an uninitialized variable	13 years ago
Serhiy Storchaka	f6d0aeeadc	Issue #16741 : Fix an error reporting in int().	13 years ago
Mark Dickinson	02515f7a3a	Minor consistency fixes for some longobject.c exception messages: - replace 'long int' / 'long' by 'int' - fix capitalization of "Python" in PyLong_AsUnsignedLong - "is too large" -> "too large", for consistency with other messages.	13 years ago
Antoine Pitrou	dcedaf6e53	Issue #18214 : Improve finalization of Python modules to avoid setting their globals to None, in most cases.	13 years ago
Antoine Pitrou	796564c27b	Issue #18112 : PEP 442 implementation (safe object finalization).	13 years ago
Victor Stinner	5b3b1006bb	Issue #18520 : Fix _PyDict_GetItemId(), suppress _PyUnicode_FromId() error As PyDict_GetItem(), _PyDict_GetItemId() suppresses all errors that may occur, for historical reasons.	13 years ago
Victor Stinner	34f96b8dd3	Issue #18520 : Fix PyFunction_NewWithQualName() error handling	13 years ago
Victor Stinner	4d1f5d6eee	Reindent PyFunction_NewWithQualName()	13 years ago
Victor Stinner	1c8f059019	Issue #18520 : Add a new PyStructSequence_InitType2() function, same than PyStructSequence_InitType() except that it has a return value (0 on success, -1 on error). * PyStructSequence_InitType2() now raises MemoryError on memory allocation failure * Fix also some calls to PyDict_SetItemString(): handle error	13 years ago
Christian Heimes	c731bbe665	Propagate error when PyByteArray_Resize() fails in bytearray_translate() CID 715334	13 years ago
Christian Heimes	26532f7519	Check return value of PyType_Ready(&EncodingMapType) CID 486654	13 years ago
Christian Heimes	de4d183955	Issue #18327 : Fix argument order in call to compatible_for_assignment(oldto, newto, attr). The fix only affects the error message of __class__ assignment. CID 983564	13 years ago
Victor Stinner	2c40f640d9	Issue #18408 : Fix list_ass_slice(), handle list_resize() failure I tested the patch manually by injecting a fault using gdb: list items are correctly restored on failure.	13 years ago
Victor Stinner	8e47832737	Issue #18408 : PyObject_Str(), PyObject_Repr() and type_call() now fail with an assertion error if they are called with an exception set (PyErr_Occurred()). As PyEval_EvalFrameEx(), they may clear the current exception and so the caller looses its exception.	13 years ago
Victor Stinner	f97dfd7b59	Issue #18408 : Fix dict_repr(), don't call PyObject_Repr() with an exception set PyObject_Repr() can removes the current exception. For example, module_repr() calls PyErr_Clear() if calling loader.module_repr(mod) failed.	13 years ago
Victor Stinner	08a80b11ad	longobject.c: add an assertion to ensure that MEDIUM_VALUE() is only called on small integers (0 or 1 digit)	13 years ago
Victor Stinner	8aed6f1c7d	Issue #18408 : Rewrite NEGATE() macro in longobject.c to handle PyLong_FromLong() failure	13 years ago

Victor Stinner	9a146eeadb	Issue #18408 : Fix structseq_reduce(), handle PyDict_SetItemString() failure	13 years ago
Victor Stinner	26f91999b4	Close #18469 : Replace PyDict_GetItemString() with _PyDict_GetItemId() in structseq.c _PyDict_GetItemId() is more efficient: it only builds the Unicode string once. Identifiers (dictionary keys) are now created at Python initialization, and if the creation failed, Python does exit with a fatal error. Before, PyDict_GetItemString() failure was not handled: structseq_new() could call PyObject_GC_NewVar() with a negative size, and structseq_dealloc() could also crash.	13 years ago
Victor Stinner	3997cfdb7f	Cleanup type_call() to ease debug It was easy to miss the call to type->tp_init because it was done in a long conditional expression. Split the long expression in multiple lines to make the debug step by step easier.	13 years ago
Victor Stinner	1b63493ed1	Issue #18408 : Py_ReprLeave() now saves/restores the current exception, and ignores exceptions raised during the call	13 years ago
Victor Stinner	ac2a4fe8a2	Issue #18408 : dict_new() now fails on new_keys_object() error Pass the MemoryError exception to the caller, instead of using empty keys.	13 years ago
Victor Stinner	a9f61a5a23	Cleanup dictobject.c	13 years ago
Victor Stinner	fdcbab9602	Issue #18408 : Fix PyDict_GetItemString(), suppress PyUnicode_FromString() error As PyDict_GetItem(), PyDict_GetItemString() suppresses all errors that may occur for historical reasons.	13 years ago
Victor Stinner	32fd6eab1e	Issue #18408 : Fix list.extend(), handle list_resize() failure	13 years ago
Victor Stinner	f243ee4055	Issue #18408 : add more assertions on PyErr_Occurred() in ceval.c to detect bugs earlier	13 years ago
Victor Stinner	53510cda59	Issue #18408 : type_new() and PyType_FromSpecWithBases() now raise MemoryError on memory allocation failure	13 years ago
Victor Stinner	e699e5a218	Issue #18408 : Don't check unicode consistency in _PyUnicode_HAS_UTF8_MEMORY() and _PyUnicode_HAS_WSTR_MEMORY() macros These macros are called in unicode_dealloc(), whereas the unicode object can be "inconsistent" if the creation of the object failed. For example, when unicode_subtype_new() fails on a memory allocation, _PyUnicode_CheckConsistency() fails with an assertion error because data is NULL.	13 years ago
