bpo-38061: subprocess uses closefrom() on FreeBSD (GH-19697)
Optimize the subprocess module on FreeBSD using closefrom().
A single close(fd) syscall is cheap, but when sysconf(_SC_OPEN_MAX)
is high, the loop calling close(fd) on each file descriptor can take
several milliseconds.

The workaround on FreeBSD to improve performance was to load and
mount the fdescfs kernel module, but this is not enabled by default.

Initial patch by Ed Maste (emaste), Conrad Meyer (cem), Kyle Evans
(kevans) and Kubilay Kocak (koobs):

bpo-39562: Prevent collision of future and compiler flags (GH-19230)
The constant values of future flags in the __future__ module
is updated in order to prevent collision with compiler flags.
Previously PyCF_ALLOW_TOP_LEVEL_AWAIT was clashing
with CO_FUTURE_DIVISION.

bpo-40286: Add randbytes() method to random.Random (GH-19527)
Add random.randbytes() function and random.Random.randbytes()
method to generate random bytes.

Modify secrets.token_bytes() to use SystemRandom.randbytes()
rather than calling directly os.urandom().

Rename also genrand_int32() to genrand_uint32(), since it returns an
unsigned 32-bit integer, not a signed integer.

The _random module is now built with Py_BUILD_CORE_MODULE defined.

Line endings within attributes were previously normalized to "\n" in Py3.7/3.8.
This patch removes that normalization, as line endings which were
replaced by entity numbers should be preserved in original form.

with subinterpreters, which don't support daemon threads.

bpo-40010: Optimize signal handling in multithreaded applications (GH-19067)
If a thread different than the main thread gets a signal, the
bytecode evaluation loop is no longer interrupted at each bytecode
instruction to check for pending signals which cannot be handled.
Only the main thread of the main interpreter can handle signals.

Previously, the bytecode evaluation loop was interrupted at each
instruction until the main thread handles signals.

Changes:

* COMPUTE_EVAL_BREAKER() and SIGNAL_PENDING_SIGNALS() no longer set
  eval_breaker to 1 if the current thread cannot handle signals.
* take_gil() now always recomputes eval_breaker.

bpo-39984: Move pending calls to PyInterpreterState (GH-19066)
If Py_AddPendingCall() is called in a subinterpreter, the function is
now scheduled to be called from the subinterpreter, rather than being
called from the main interpreter.

Each subinterpreter now has its own list of scheduled calls.

* Move pending and eval_breaker fields from _PyRuntimeState.ceval
  to PyInterpreterState.ceval.
* new_interpreter() now calls _PyEval_InitThreads() to create
  pending calls lock.
* Fix Py_AddPendingCall() for subinterpreters. It now calls
  _PyThreadState_GET() which works in a subinterpreter if the
  caller holds the GIL, and only falls back on
  PyGILState_GetThisThreadState() if _PyThreadState_GET()
  returns NULL.

bpo-39824: module_traverse() don't call m_traverse if md_state=NULL (GH-18738)
Extension modules: m_traverse, m_clear and m_free functions of
PyModuleDef are no longer called if the module state was requested
but is not allocated yet. This is the case immediately after the
module is created and before the module is executed (Py_mod_exec
function). More precisely, these functions are not called if m_size is
greater than 0 and the module state (as returned by
PyModule_GetState()) is NULL.

Extension modules without module state (m_size <= 0) are not affected.

It is equal to "lib" on most platforms. On Fedora and SuSE, it is
equal to "lib64" on 64-bit systems.

bpo-39491: Merge PEP 593 (typing.Annotated) support (#18260)
* 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

This exposes a Linux-specific syscall for sending a signal to a process

Python also doesn't support.

Greg Price 2f09413947 closes bpo-37966: Fully implement the UAX #15 quick-check algorithm. (GH-15558)
The purpose of the `unicodedata.is_normalized` function is to answer
the question `str == unicodedata.normalized(form, str)` more
efficiently than writing just that, by using the "quick check"
optimization described in the Unicode standard in UAX #15.

However, it turns out the code doesn't implement the full algorithm
from the standard, and as a result we often miss the optimization and
end up having to compute the whole normalized string after all.

Implement the standard's algorithm.  This greatly speeds up
`unicodedata.is_normalized` in many cases where our partial variant
of quick-check had been returning MAYBE and the standard algorithm
returns NO.

At a quick test on my desktop, the existing code takes about 4.4 ms/MB
(so 4.4 ns per byte) when the partial quick-check returns MAYBE and it
has to do the slow normalize-and-compare:

  $ build.base/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \
      -- 'unicodedata.is_normalized("NFD", s)'
  50 loops, best of 5: 4.39 msec per loop

With this patch, it gets the answer instantly (58 ns) on the same 1 MB
string:

  $ build.dev/python -m timeit -s 'import unicodedata; s = "\uf900"*500000' \
      -- 'unicodedata.is_normalized("NFD", s)'
  5000000 loops, best of 5: 58.2 nsec per loop

This restores a small optimization that the original version of this
code had for the `unicodedata.normalize` use case.

With this, that case is actually faster than in master!

$ build.base/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \
    -- 'unicodedata.normalize("NFD", s)'
500 loops, best of 5: 561 usec per loop

$ build.dev/python -m timeit -s 'import unicodedata; s = "\u0338"*500000' \
    -- 'unicodedata.normalize("NFD", s)'
500 loops, best of 5: 512 usec per loop

bpo-37663: have venv activation scripts all consistently use __VENV_PROMPT__ for prompt customization (GH-14941)
The activation scripts generated by venv were inconsistent in how they changed the shell's prompt. Some used `__VENV_PROMPT__` exclusively, some used `__VENV_PROMPT__` if it was set even though by default `__VENV_PROMPT__` is always set and the fallback matched the default, and one ignored `__VENV_PROMPT__` and used `__VENV_NAME__` instead (and even used a differing format to the default prompt). This change now has all activation scripts use `__VENV_PROMPT__` only and relies on the fact that venv sets that value by default.

The color of the customization is also now set in fish to the blue from the Python logo for as hex color support is built into that shell (much like PowerShell where the built-in green color is used).

do so in a non-disruptive manner.

argument is sometimes ignored for empty strings.

Python now gets the absolute path of the script filename specified on

the __main__ module, sys.argv[0] and sys.path[0] become an absolute

* Add _Py_isabs() and _Py_abspath() functions.
* _PyConfig_Read() now tries to get the absolute path of
  run_filename, but keeps the relative path if _Py_abspath() fails.
* Reimplement os._getfullpathname() using _Py_abspath().
* Use _Py_isabs() in getpath.c.

PyObject_CallNoArgs(func) only allocates 624 bytes per call.

It is excluded from stable ABI 3.8.

PyObject_CallNoArgs() in C extensions: _asyncio, _datetime,
_elementtree, _pickle, _tkinter and readline.
