* bpo-44571: Add itertool recipe for a variant of takewhile() (GH-28167)Miss Islington (bot)2021-09-051-0/+49
| | | | | (cherry picked from commit 91be41ad933e24bff26353a19f56447e17fb6367) Co-authored-by: Raymond Hettinger <rhettinger@users.noreply.github.com>
* bpo-42536: GC track recycled tuples (GH-23623)Brandt Bucher2020-12-051-0/+47
| | | | | | | | | | | | | | | | Several built-in and standard library types now ensure that their internal result tuples are always tracked by the garbage collector: - collections.OrderedDict.items - dict.items - enumerate - functools.reduce - itertools.combinations - itertools.combinations_with_replacement - itertools.permutations - itertools.product - itertools.zip_longest - zip Previously, they could have become untracked by a prior garbage collection.

* bpo-34410: Fix a crash in the tee iterator when re-enter it. (GH-15625)Serhiy Storchaka2019-09-091-0/+37

* bpo-37707: Exclude expensive unit tests from PGO task (GH-15009)Neil Schemenauer2019-07-301-0/+1
| | | | | Mark some individual tests to skip when --pgo is used. The tests marked increase the PGO task time significantly and likely don't help improve optimization of the final executable.

* bpo-29942: Fix the use of recursion in itertools.chain.from_iterable. (#889)T. Wouters2017-03-301-0/+8
| | | | | Fix the use of recursion in itertools.chain.from_iterable. Using recursion is unnecessary, and can easily cause stack overflows, especially when building in low optimization modes or with Py_DEBUG enabled.
