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.

The functions in this chapter are specific to certain Python object types.
|
|
Passing them an object of the wrong type is not a good idea; if you receive an
|
|
object from a Python program and you are not sure that it has the right type,
|
|
you must perform a type check first; for example, to check that an object is a
|
|
dictionary, use :c:func:`PyDict_Check`. The chapter is structured like the
|
|
"family tree" of Python object types.
|
|
|
|
.. warning::
|
|
|
|
While the functions described in this chapter carefully check the type of the
|
|
objects which are passed in, many of them do not check for ``NULL`` being passed
|
|
instead of a valid object. Allowing ``NULL`` to be passed in can cause memory
|
|
access violations and immediate termination of the interpreter.

Sequence Objects

|

Generic operations on sequence objects were discussed in the previous chapter;
|
|
this section deals with the specific kinds of sequence objects that are
|
|
intrinsic to the Python language.
