Subject: [PATCH] 00251: Change user install location
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Set values of base and platbase in sysconfig from /usr
to /usr/local when RPM build is not detected
to make pip and similar tools install into separate location.
Fedora Change: https://fedoraproject.org/wiki/Changes/Making_sudo_pip_safe
Downstream only.
We've tried to rework in Fedora 36/Python 3.10 to follow https://bugs.python.org/issue43976
but we have identified serious problems with that approach,
see https://bugzilla.redhat.com/2026979 or https://bugzilla.redhat.com/2097183
pypa/distutils integration: https://github.com/pypa/distutils/pull/70

Subject: [PATCH] 00415: [CVE-2023-27043] gh-102988: Reject malformed addresses
in email.parseaddr() (#111116)
Detect email address parsing errors and return empty tuple to
indicate the parsing error (old API). Add an optional 'strict'
parameter to getaddresses() and parseaddr() functions. Patch by
Thomas Dwyer.

Subject: [PATCH] 00425: Only check for 'test/wheeldata' when it's actually
used
We build Python in Fedora 39+ with option `--with-wheel-pkg-dir`
pointing to a custom wheel directory and delete the contents of
upstream's `test/wheeldata`. Don't include the directory in the test set
if the wheels are used from a different location.

<p>
IDLE is Python’s Integrated Development and Learning Environment.
The GUI is uniform between Windows, Unix, and Mac OS X.
IDLE provides an easy way to start writing, running, and debugging
Python code.
</p>
<p>
IDLE is written in pure Python, and uses the tkinter GUI toolkit.
It provides:
</p>
<ul>
<li>a Python shell window (interactive interpreter) with colorizing of code input, output, and error messages,</li>
<li>a multi-window text editor with multiple undo, Python colorizing, smart indent, call tips, auto completion, and other features,</li>
<li>search within any window, replace within editor windows, and search through multiple files (grep),</li>
<li>a debugger with persistent breakpoints, stepping, and viewing of global and local namespaces.</li>
</ul>
