- Tools/Demos
- gh-130453: Allow passing multiple keyword arguments with
the same function name in pygettext.
- gh-130195: Add warning messages when pygettext
unimplemented -a/--extract-all option is called.
- Tests
- gh-133131: The iOS testbed will now select the most
recently released “SE-class” device for testing if a device
isn’t explicitly specified.
- gh-91048: Add ability to externally inspect all pending
asyncio tasks, even if no task is currently entered on the
event loop.
- gh-109981: The test helper that counts the list of open
file descriptors now uses the optimised /dev/fd approach on
all Apple platforms, not just macOS. This avoids crashes
caused by guarded file descriptors.
- gh-132678: Add --prioritize to -m test. This option allows
the user to specify which selected tests should execute
first, even if the order is otherwise randomized. This is
particularly useful for tests that run the longest.
- gh-131290: Tests in Lib/test can now be correctly executed
as standalone scripts.
- Security
- gh-115322: The underlying extension modules behind
readline:, subprocess, and ctypes now raise audit events
on previously uncovered code paths that could lead to file
system access related to C function calling and external
binary execution. The ctypes.call_function audit hook has
also been fixed to use an unsigned value for its function

Notes for packagers of Python3

==============================

|
|
|
0. Faster build turnaround
|
|
--------------------------
|
|
|
|
By default, python builds with profile-guided optimization. This needs
|
|
an additional run of the test suite and it is generally slow.
|
|
PGO build takes around 50 minutes.
|
|
|
|
For development, use "--without profileopt" option to disable PGO. This
|
|
shortens the build time to ~5 minutes including test suite.
|
|
|
|
1. import_failed.map
|
|
----------------------
|
|
|
|
This is a mechanism installed as part of python3-base, that places shim modules
|
|
on python's path (through a generated zzzz-import-failed-hooks.pth file, so that
|
|
it is imported as much at the end as makes sense; and an _import_failed subdir
|
|
of /usr/lib/pythonX.Y). Then when the user tries to import a module that is part
|
|
of a subpackage, the ImportError will contain a helpful message telling them
|
|
which missing subpackage to install.
|
|
|
|
This can sometimes cause problems on non-standard configurations, if the pth
|
|
gets included too early (for instance if you are using a script to include all
|
|
pths by hand in some strange order). Just something to look out for.
