v2.2.2 (2014-08-08)


  • allow storing non-reserved attribute names starting with an underscore Previous versions of ArangoDB parsed away all attribute names that started with an underscore (e.g. _test, _foo, _bar) on all levels of a document (root level and sub-attribute levels). While this behavior was documented, it was unintuitive and prevented storing documents inside other documents, e.g.:

In the above example, previous versions of ArangoDB removed all attributes and sub-attributes that started with underscores, meaning the embedded documents would lose some of their attributes. 2.2.2 should preserve such attributes, and will also allow storing user-defined attribute names on the top-level even if they start with underscores (such as _type in the above example).

  • fix conversion of JavaScript String, Number and Boolean objects to JSON. Objects created in JavaScript using new Number(...), new String(...), or new Boolean(...) were not converted to JSON correctly.
  • fixed a race condition on task registration (i.e. require("org/arangodb/tasks").register()) this race condition led to undefined behavior when a just-created task with no offset and no period was instantly executed and deleted by the task scheduler, before the register function returned to the caller.
  • changed run-tests.sh to execute all suitable tests.
  • switch to new version of gyp
  • fixed upgrade button
