Jan Steemann 3744e8dde9 issue #796: Searching with newline chars broken? 2014-04-22 13:38:06 +02:00
Jan Steemann ba8e38d6e5 bugfix for AQL query optimiser 
the following type of query was too eagerly optimised, leading to errors in code-generation:

   LET a = (FOR i IN [] RETURN i) LET b = (FOR i IN [] RETURN i) RETURN 1

the problem occurred when both lists in the subqueries were empty. In this case invalid code
was generated and the query couldn't be executed.

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.
