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.

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.
