jinja2.sandbox
~~~~~~~~~~~~~~
Adds a sandbox layer to Jinja as it was the default behavior in the old
Jinja 1 releases. This sandbox is slightly different from Jinja 1 as the
default behavior is easier to use.
The behavior can be changed by subclassing the environment.

Test if the attribute given is an internal python attribute. For
example this function returns `True` for the `func_code` attribute of
python objects. This is useful if the environment method
:meth:`~SandboxedEnvironment.is_safe_attribute` is overridden.

rA c C s( x"t D ]\}}t| |�r||kS qW dS )a� This function checks if an attribute on a builtin mutable object
(list, dict, set or deque) would modify it if called. It also supports
the "user"-versions of the objects (`sets.Set`, `UserDict.*` etc.) and
with Python 2.6 onwards the abstract base classes `MutableSet`,
`MutableMapping`, and `MutableSequence`.
>>> modifies_known_mutable({}, "clear")

>>> modifies_known_mutable({}, "keys")

If called with an unsupported object (such as unicode) `False` is
returned.

tells the compiler to generate sandboxed code. Additionally subclasses of
this environment may override the methods that tell the runtime what
attributes or functions are safe to access.
If the template tries to access insecure code a :exc:`SecurityError` is
raised. However also other exceptions may occour during the rendering so
the caller has to ensure that all exceptions are catched.
T)�+�-�*�/z//z**�%)rE rF c C s dS )a� Called during template compilation with the name of a unary
operator to check if it should be intercepted at runtime. If this
method returns `True`, :meth:`call_unop` is excuted for this unary
operator. The default implementation of :meth:`call_unop` will use
the :attr:`unop_table` dictionary to perform the operator with the
same logic as the builtin one.
The following unary operators are interceptable: ``+`` and ``-``
Intercepted calls are always slower than the native operator call,
so make sure only to intercept the ones you are interested in.
