# HG changeset patch # User Goffi # Date 1396026442 -3600 # Node ID e1842ebcb2f35181b626cc0aeeac0ee815c37cbc # Parent 71926ec2114d3f3626fc6beaed627de3d9cb7f3a core, plugin XEP-0115: discovery refactoring: - hashing algorithm of XEP-0115 has been including in core - our own hash is still calculated by XEP-0115 and can be regenerated with XEP_0115.recalculateHash - old discovery methods have been removed. Now the following methods are used: - hasFeature: tell if a feature is available for an entity - getDiscoInfos: self explaining - getDiscoItems: self explaining - findServiceEntities: return all available items of an entity which given (category, type) - findFeaturesSet: search for a set of features in entity + entity's items all these methods are asynchronous, and manage cache automatically - XEP-0115 manage in a better way hashes, and now use a trigger for presence instead of monkey patch - new FeatureNotFound exception, when we want to do something which is not available - refactored client initialisation sequence, removed client.initialized Deferred - added constant APP_URL - test_plugin_xep_0033.py has been temporarly deactivated, the time to adapt it -
