+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

+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.

++:func:`email.utils.getaddresses` and :func:`email.utils.parseaddr` now
++return ``('', '')`` 2-tuples in more situations where invalid email
++addresses are encountered instead of potentially inaccurate values. Add
++optional *strict* parameter to these two functions: use ``strict=False`` to
++get the old behavior, accept malformed inputs.
++``getattr(email.utils, 'supports_strict_parsing', False)`` can be use to check
++if the *strict* paramater is available. Patch by Thomas Dwyer and Victor
++Stinner to improve the CVE-2023-27043 fix.

+      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>
