Jan Steemann 5ba2432d78 remove sort in more cases 2016-02-10 11:23:11 +01:00
jsteemann a02e2b563f fixed issue #1707: 2.8.1 crashes 
the crash was due to a required variable being removed from the execution plan.
this happened when there were multiple execution plans, and a certain transformation
was made in one of them. the transformation modified an element that was shared by
all plans, but it should have made a copy so only the current plan is affected

Michael Hackstein c2338d80d0 A user can now create an indux on attribute[*] which will put an index on attribute and ignores the expand flag. Does not harm any feature in AQL now. 2015-08-17 12:43:08 +02:00
Michael Hackstein 17a8f73a06 Now the input for indexes is parsed using the new attribute parser. This means the flags for expanded Attributes are set. Also introduced a transformation function to transform an attributeName list back into a string. 2015-08-17 12:43:07 +02:00
Michael Hackstein 8fbb2739b0 The indexes can now use the new AttributeName struct which contains a flag if the attribute should be Array-Indexed. Right now this flag is hard-coded to false in all cases and not persisted. 2015-08-17 12:43:05 +02:00
