* bpo-39491: Merge PEP 593 (typing.Annotated) support (#18260)Jakub Stasiak2020-02-051-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | * bpo-39491: Merge PEP 593 (typing.Annotated) support PEP 593 has been accepted some time ago. I got a green light for merging this from Till, so I went ahead and combined the code contributed to typing_extensions[1] and the documentation from the PEP 593 text[2]. My changes were limited to: * removing code designed for typing_extensions to run on older Python versions * removing some irrelevant parts of the PEP text when copying it over as documentation and otherwise changing few small bits to better serve the purpose * changing the get_type_hints signature to match reality (parameter names) I wasn't entirely sure how to go about crediting the authors but I used my best judgment, let me know if something needs changing in this regard.

| | | | | | | | This exposes a Linux-specific syscall for sending a signal to a process identified by a file descriptor rather than a pid. For simplicity, we don't support the siginfo_t parameter to the syscall. This parameter allows implementing a pidfd version of rt_sigqueueinfo(2), which Python also doesn't support.
* bpo-28286: Deprecate opening GzipFile for writing implicitly. (GH-16417)Serhiy Storchaka2019-11-161-0/+6
