Red Bear OS is a full fork. All sources must be available from git clone with zero network access. Removed gitignore rules that excluded fetched source trees under recipes/*/source/, local/recipes/kde/*/source/, local/recipes/qt/*/source/, and vendor source trees. Build artifacts (target/, build/, source.tar, *.o, *.so) remain excluded. 127291 files added — kernel, relibc, base, bootloader, pkgar, all KDE/Qt frameworks, mesa, wayland, DRM drivers, and every other recipe source.

"""BaseHTTPServer that implements the Python WSGI protocol (PEP 3333)
|
|
|
|
This is both an example of how WSGI can be implemented, and a basis for running
|
|
simple web applications on a local machine, such as might be done when testing
|
|
or debugging an application. It has not been reviewed for security issues,
|
|
however, and we strongly recommend that you use a "real" web server for
|
|
production use.
|
|
|
|
For example usage, see the 'if __name__=="__main__"' block at the end of the
|
|
module. See also the BaseHTTPServer module docs for other API information.
