Jan Steemann e359dc29dd INCOMPATIBLE CHANGE: changed AQL user function namespace resolution operator from `:` to `::` 
AQL user-defined functions were introduced in ArangoDB 1.3, and the namespace resolution
operator for them was the single colon (`:`). A function call looked like this:

    RETURN mygroup:myfunc()

The single colon caused an ambiguity in the AQL grammar, making it indistinguishable from
named attributes or the ternary operator in some cases, e.g.

    { mygroup:myfunc ? mygroup:myfunc }

The change of the namespace resolution operator from `:` to `::` fixes this ambiguity.

Existing user functions in the database will be automatically fixed when starting ArangoDB
1.4 with the `--upgrade` option. However, queries using user-defined functions need to be
adjusted on the client side to use the new operator.

Jan Steemann 2a286dc074 updated documentation for #557 2013-06-27 11:33:21 +02:00
Jan Steemann 9599a021b9 moved some graph traversal validation into the traversal module 
- that simplifies some of the traversal-calling routines
- make returning error codes more consistent (specific 404 errors when
referring to unknown collections instead of simple 400 errors)
- optionally limit traversals to a certain number of iterations so they
  don't run endlessly in cyclic graphs
