| | | | | | | :mod:`hashlib` no longer falls back to builtin hash implementations when OpenSSL provides a hash digest and the algorithm is blocked by security policy. Signed-off-by: Christian Heimes <christian@python.org>

* Cosmetic smtplib changes (GH-8718)Ville Skyttä2020-05-232-6/+7
| | | | | Some cosmetic smtplib changes here. Let me know if you'd like a bpo/news entry or splitting this PR into two. Automerge-Triggered-By: @maxking
* bpo-40552 Add 'users' variable in code sample (tutorial 4.2). (GH-19992)Antoine2020-05-232-0/+5
| | | | | | | * Add 'users' variable in code sample. * 📜🤖 Added by blurb_it. Co-authored-by: blurb-it[bot] <43283697+blurb-it[bot]@users.noreply.github.com>
* bpo-40679: Use the function's qualname in certain TypeErrors (GH-20236)Dennis Sweeney2020-05-224-16/+68
| | | | Patch by Dennis Sweeney.
* bpo-40696: Fix a hang that can arise after gen.throw() (GH-20287)Chris Jerdonek2020-05-227-23/+130
| | | | | | | | This updates _PyErr_ChainStackItem() to use _PyErr_SetObject() instead of _PyErr_ChainExceptions(). This prevents a hang in certain circumstances because _PyErr_SetObject() performs checks to prevent cycles in the exception context chain while _PyErr_ChainExceptions() doesn't.
* bpo-9216: hashlib usedforsecurity fixes (GH-20258)Christian Heimes2020-05-226-34/+90
| | | | | | | | | func:`hashlib.new` passed ``usedforsecurity`` to OpenSSL EVP constructor ``_hashlib.new()``. test_hashlib and test_smtplib handle strict security policy better. Signed-off-by: Christian Heimes <christian@python.org> Automerge-Triggered-By: @tiran

* Let the argument clinic do the type checking for heapq (GH-20284)Raymond Hettinger2020-05-222-46/+117

* bpo-40630: Add tracemalloc.reset_peak (GH-20102)Huon Wilson2020-05-227-1/+138
| | | | | | | The reset_peak function sets the peak memory size to the current size, representing a resetting of that metric. This allows for recording the peak of specific sections of code, ignoring other code that may have had a higher peak (since the most recent `tracemalloc.start()` or tracemalloc.clear_traces()` call).
* Restore missing column of digits (GH-20313)Raymond Hettinger2020-05-221-30/+30

* Fix debug output in PEG parser generator (GH-20308)Pablo Galindo2020-05-221-3/+3

* bpo-40334: Produce better error messages for non-parenthesized genexps ↵Lysandros Nikolaou2020-05-225-6/+79
| | | | | | (GH-20153) The error message, generated for a non-parenthesized generator expression in function calls, was still the generic `invalid syntax`, when the generator expression wasn't appearing as the first argument in the call. With this patch, even on input like `f(a, b, c for c in d, e)`, the correct error message gets produced.

* Reword aware/naive introduction sentence (GH-20175)Mathieu Dupuy2020-05-211-1/+2
| | | | | This is more informative and avoids the question of whether the period should go inside or outside the quotation marks. See also GH-20007.
* bpo-40334: Correctly generate C parser when assigned var is None (GH-20296)Batuhan Taskaya2020-05-211-1/+4
| | | | | When there are 2 negative lookaheads in the same rule, let's say `!"(" blabla "," !")"`, there will the 2 `FunctionCall`'s where assigned value is None. Currently when the `add_var` is called the first one will be ignored but when the second lookahead's var is sent to dedupe it will be returned as `None_1` and this won't be ignored by the declaration generator in the `visit_Alt`. This patch adds an explicit check to `add_var` to distinguish whether if there is a variable or not.

* bpo-32309: Add support for contextvars in asyncio.to_thread() (GH-20278)Kyle Stanley2020-05-213-3/+25
| | | | | Allows contextvars from the main thread to be accessed in the separate thread used in `asyncio.to_thread()`. See the [discussion](https://github.com/python/cpython/pull/20143#discussion_r427808225) in GH-20143 for context. Automerge-Triggered-By: @aeros
