* gh-84436: Implement Immortal Objects (gh-19474)Eddie Elizondo2023-04-221-0/+7
| | | | | | | | | This is the implementation of PEP683 Motivation: The PR introduces the ability to immortalize instances in CPython which bypasses reference counting. Tagging objects as immortal allows up to skip certain operations when we know that the object will be around for the entire execution of the runtime. Note that this by itself will bring a performance regression to the runtime due to the extra reference count checks. However, this brings the ability of having truly immutable objects that are useful in other contexts such as immutable data sharing between sub-interpreters.

| | | | | | | | | | | | | | | | Integer to and from text conversions via CPython's bignum `int` type is not safe against denial of service attacks due to malicious input. Very large input strings with hundred thousands of digits can consume several CPU seconds. This PR comes fresh from a pile of work done in our private PSRT security response team repo.

* gh-91838: Use HTTPS links in docs for resources which redirect to HTTPS ↵Serhiy Storchaka2022-08-041-1/+1
| | | | | | | | | | (GH-95527) If an HTTP link is redirected to a same looking HTTPS link, the latter can be used directly without changes in readability and behavior. It protects from a men-in-the-middle attack. This change does not affect Python examples.

* gh-91181: drop support for bytes on sys.path (GH-31934)Thomas Grainger2022-07-171-1/+1
| | | | | | Support for bytes broke sometime between Python 3.2 and 3.6 and has been broken ever since. Trying to bring back supports is surprisingly difficult in the face of -b and checking for keys in sys.path_importer_cache. Since the support was broken for so long, trying to overcome the difficulty of bringing back the support has been deemed not worth it.

* bpo-45353: Remind sys.modules users to copy when iterating. (GH-28842)Gregory P. Smith2021-10-091-1/+5
| | | | | | | | This is true of all dictionaries in Python, but this one tends to catch people off guard as they don't realize when sys.modules might change out from underneath them as a hidden side effect of their code. Copying it first avoids the RuntimeError. An example when this happens in single threaded code are codecs being loaded which are an implicit time of use import that most need not think about.
* bpo-43284: Update platform.win32_ver to use _syscmd_ver instead of ↵Shreyan Avigyan2021-04-221-1/+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.
