* Fix thread locks in zlib module may go wrong in rare case. (#22126)Ma Lin2021-04-271-0/+1
| | | Setting `next_in` before acquiring the thread lock may mix up compress/decompress state in other threads.
* bpo-43945: [Enum] Deprecate non-standard mixin format() behavior (GH-25649)Ethan Furman2021-04-271-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | In 3.12 the enum member, not the member's value, will be used for format() calls. Format specifiers can be used to retain the current display of enum members: Example enumeration: class Color(IntEnum): RED = 1 GREEN = 2 BLUE = 3 Current behavior: f'{Color.RED}' --> '1' Future behavior: f'{Color.RED}' --> 'RED' Using d specifier: f'{Color.RED:d}' --> '1' Using specifiers can be done now and is future-compatible.

* bpo-42904: Change search order of typing.get_type_hints eval (#25632)Ken Jin2021-04-261-0/+5
| | | While surprising (searching globals before locals in one specific case), this is needed for backwards compatibility.
* bpo-18233: Add internal methods to access peer chain (GH-25467)Christian Heimes2021-04-261-0/+2
| | | | | | | | | | | | The internal `_ssl._SSLSocket` object now provides methods to retrieve the peer cert chain and verified cert chain as a list of Certificate objects. Certificate objects have methods to convert the cert to a dict, PEM, or DER (ASN.1). These are private APIs for now. There is a slim chance to stabilize the approach and provide a public API for 3.10. Otherwise I'll provide a stable API in 3.11. Signed-off-by: Christian Heimes <christian@python.org>

* bpo-39529: Deprecate creating new event loop in asyncio.get_event_loop() ↵Serhiy Storchaka2021-04-251-0/+9
| | | | | | (GH-23554) asyncio.get_event_loop() emits now a deprecation warning when it creates a new event loop. In future releases it will became an alias of asyncio.get_running_loop().

* bpo-30555: Fix WindowsConsoleIO fails in the presence of fd redirection ↵Segev Finer2021-04-231-0/+2
| | | | | | | | (GH-1927) This works by not caching the handle and instead getting the handle from the file descriptor each time, so that if the actual handle changes by fd redirection closing/opening the console handle beneath our feet, we will keep working correctly.

* bpo-39950: add `pathlib.Path.hardlink_to()` method that supersedes ↵Barney Gale2021-04-231-0/+2
| | | | | | | | | | | `link_to()` (GH-18909) The argument order of `link_to()` is reversed compared to what one may expect, so: a.link_to(b) Might be expected to create *a* as a link to *b*, in fact it creates *b* as a link to *a*, making it function more like a "link from". This doesn't match `symlink_to()` nor the documentation and doesn't seem to be the original author's intent. This PR deprecates `link_to()` and introduces `hardlink_to()`, which has the same argument order as `symlink_to()`.

* bpo-43914: Highlight invalid ranges in SyntaxErrors (#25525)Pablo Galindo2021-04-231-0/+3
| | | | | | | | | | | | | | | | | To improve the user experience understanding what part of the error messages associated with SyntaxErrors is wrong, we can highlight the whole error range and not only place the caret at the first character. In this way: >>> foo(x, z for z in range(10), t, w) File "<stdin>", line 1 foo(x, z for z in range(10), t, w) ^ SyntaxError: Generator expression must be parenthesized becomes >>> foo(x, z for z in range(10), t, w) File "<stdin>", line 1 foo(x, z for z in range(10), t, w) ^^^^^^^^^^^^^^^^^^^^ SyntaxError: Generator expression must be parenthesized
* bpo-43868: Remove PyOS_ReadlineFunctionPointer from the stable ABI list ↵Petr Viktorin2021-04-231-0/+3
| | | | | | | | | | | (GH-25442) The inclusion of PyOS_ReadlineFunctionPointer in python3dll.c was a mistake. According to PEP 384: > functions expecting FILE* are not part of the ABI, to avoid depending > on a specific version of the Microsoft C runtime DLL on Windows. https://bugs.python.org/issue43868
* bpo-43795: PEP-652: Clean up the stable ABI/limited API (GH-25482)Petr Viktorin2021-04-231-0/+2
| | | | | | | | | | | | | | | | | | - `_Py_EncodeLocaleRaw`, which is private by name, undocumented, and wasn't exported in `python3.dll`, is moved to a private header. - `_Py_HashSecret_Initialized`, again private by name, undocumented, and not exported in `python3.dll`, is excluded with `Py_LIMITED_API`. - `PyMarshal_*` and `PyMember_*One` functions, declared in private headers and not exported in `python3.dll`, are removed from `Doc/data/stable_abi.dat`. - `PyMem_Calloc` which *was* exported in `python3dll.c`, is moved to public headers where it joins its other `PyMem_*` friends. Only the last change is documented in the blurb; others are not user-visible. (Nothing uses `Doc/data/stable_abi.dat` yet.) https://bugs.python.org/issue43795

* bpo-43284: Update platform.win32_ver to use _syscmd_ver instead of ↵Shreyan Avigyan2021-04-221-0/+6
| | | | | | | sys.getwindowsversion() (GH-25500) The sys module uses the kernel32.dll version number, which can vary from the "actual" Windows version. Since the best option for getting the version is WMI (which is expensive), we switch back to launching cmd.exe (which is also expensive, but a lot less code on our part). sys.getwindowsversion() is not updated to avoid launching executables from that module.

* bpo-36076: Add SNI support to ssl.get_server_certificate. (GH-16820)juhovh2021-04-181-0/+1
| | | | | | | | | | | | | | Many servers in the cloud environment require SNI to be used during the SSL/TLS handshake, therefore it is not possible to fetch their certificates using the ssl.get_server_certificate interface. This change adds an additional optional hostname argument that can be used to set the SNI. Note that it is intentionally a separate argument instead of using the host part of the addr tuple, because one might want to explicitly fetch the default certificate or fetch a certificate from a specific IP address with the specified SNI hostname. A separate argument also works better for backwards compatibility. Automerge-Triggered-By: GH:tiran
