Add sys.orig_argv attribute: the list of the original command line
arguments passed to the Python executable.
Rename also PyConfig._orig_argv to PyConfig.orig_argv and
document it.
The __hash__() methods of classes IPv4Interface and IPv6Interface had issue
of generating constant hash values of 32 and 128 respectively causing hash collisions.
The fix uses the hash() function to generate hash values for the objects
instead of XOR operation
- Mention that some compiler optimizations might not roundtrip
exactly (such as constant tuples and frozensets).
- Add a warning about it might raise RecursionError on very
complex expressions due to recursive unparsing aspect of ast.unparse
This commit changes the parsing of f-string expressions with the new parser. The parser gets pre-fed with the location of the expression itself (not the f-string, which was what we were doing before). This allows us to completely skip the shifting of the AST nodes after the parsing is completed.
Always create the empty bytes string singleton.
Optimize PyBytes_FromStringAndSize(str, 0): it no longer has to check
if the empty string singleton was created or not, it is always
available.
Add functions:
* _PyBytes_Init()
* bytes_get_empty(), bytes_new_empty()
* bytes_create_empty_string_singleton()
* unicode_create_empty_string_singleton()
_Py_unicode_state: rename empty structure member to empty_string.
Adds a simple check for whether or not the package is being installed in the GUI or using installer on the command line. This addresses an issue where CLI-based software management tools (such as Munki) unexpectedly open Finder windows into a GUI session during installation runs.
I've done the implementation for both non-chunked and chunked reads. I haven't benchmarked chunked reads because I don't currently have a convenient way to generate a high-bandwidth chunked stream, but I don't see any reason that it shouldn't enjoy the same benefits that the non-chunked case does. I've used the benchmark attached to the bpo bug to verify that performance now matches the unsized read case.

In absence of explicit declaration, resource compiler uses system
codepage. When this codepage is DBCS or UTF-8, Python's copyright
string is corrupted, because it contains copyright sign encoded
as \xA9.
The fix is to explicitly declare codepage 1252.
Py_InitializeFromConfig() now always creates the empty tuple
singleton as soon as possible.
Optimize PyTuple_New(0): it no longer has to check if the empty tuple
was created or not, it is always creatd.
* Add tuple_create_empty_tuple_singleton() function.
* Add tuple_get_empty() function.
* Remove state parameter of tuple_alloc().
