gorilla.default_filter(name, obj)[source]

Attribute filter.

It filters out module attributes, and also methods starting with an underscore _.

This is used as the default filter for the create_patches() function and the patches() decorator.

Parameters:
  • name (str) – Attribute name.
  • obj (object) – Attribute value.
Returns:

Whether the attribute should be returned.
Return type:

bool
gorilla.create_patches(destination, root, settings=None, traverse_bases=True, filter=<function default_filter>, recursive=True, use_decorators=True)[source]

Create a patch for each member of a module or a class.

Parameters:
  • destination (object) – Patch destination.
  • root (object) – Root object, either a module or a class.
  • settings (gorilla.Settings) – Settings.
  • traverse_bases (bool) – If the object is a class, the base classes are also traversed.
  • filter (function) – Attributes for which the function returns False are skipped. The function needs to define two parameters: name, the attribute name, and obj, the attribute value. If None, no attribute is skipped.
  • recursive (bool) – If True, and a hit occurs due to an attribute at the destination already existing with the given name, and both the member and the target attributes are classes, then instead of creating a patch directly with the member attribute value as is, a patch for each of its own members is created with the target as new destination.
  • use_decorators (bool) – True to take any modifier decorator into consideration to allow for more granular customizations.
Returns:

The patches.
Return type:

list of gorilla.Patch

Note

A ‘target’ differs from a ‘destination’ in that a target represents an existing attribute at the destination about to be hit by a patch.

patches()

gorilla.find_patches(modules, recursive=True)[source]

Find all the patches created through decorators.

Parameters:
  • modules (list of module) – Modules and/or packages to search the patches in.
  • recursive (bool) – True to search recursively in subpackages.
Returns:

Patches found.
Return type:

list of gorilla.Patch
Raises:

TypeError – The input is not a valid package or module.

patch(), patches()

gorilla.get_attribute(obj, name)[source]

Retrieve an attribute while bypassing the descriptor protocol.

As per the built-in getattr() function, if the input object is a class then its base classes might also be searched until the attribute is found.

Parameters:
  • obj (object) – Object to search the attribute in.
  • name (str) – Name of the attribute.
Returns:

The attribute found.
Return type:

object
Raises:

AttributeError – The attribute couldn’t be found.
gorilla.get_original_attribute(obj, name, id='default')[source]

Retrieve an overriden attribute that has been stored.

Parameters:
  • obj (object) – Object to search the attribute in.
  • name (str) – Name of the attribute.
  • id (str) – Identifier of the original attribute to retrieve from the stack.
Returns:

The attribute found.
Return type:

object
Raises:

AttributeError – The attribute couldn’t be found.

gorilla.get_decorator_data(obj, set_default=False)[source]

Retrieve any decorator data from an object.

Parameters:
  • obj (object) – Object.

Returns:

The decorator data or None.
Return type:
