Jan Steemann a12eda295b aha! 2015-10-06 13:03:46 +02:00
Michael Hackstein e55b5d59d5 Implemented IndexIterator for PrimaryIndex. The IndexBlock uses this Iterator. Still a double free as soon as the query is finished 2015-10-01 14:34:24 +02:00
Michael Hackstein 468e632abb Merge branch 'aql-jmmh-conditions' of github.com:arangodb/arangodb into aql-jmmh-conditions 2015-09-30 08:38:26 +02:00

Michael Hackstein e35ea8995e Fixed used after free of condition node. Cloned the Condition AST whie handing it over. Still get a double free exception. IndexNodeis now handled. 2015-09-29 09:13:08 +02:00
Michael Hackstein 1e9c6f110b Started implementing the IndexBlock. Right now it expects an iterator for each used index that is created by an evaluated expression from the Block. Then it will go through all iterators in every get/skip some step 2015-09-28 19:30:10 +02:00
Jan Steemann 84f59d112e unified index use checks 2015-09-28 18:13:04 +02:00
Jan Steemann 3495816fa1 changed index signatures 2015-09-28 14:11:23 +02:00
Michael Hackstein 6a11ad28ee Adapted all indices to the new planned interface so they tell us if they can serve for a condition and present their costs 2015-09-25 10:40:04 +02:00
Michael Hackstein eae6394f22 Allowed the hashIndex to modify the DNF and-block node. It now successfully removes all entries it can be responsible for 2015-09-23 16:29:15 +02:00
Michael Hackstein aefc0edae0 Added a modifyable AST node to the index can serve and block functionality of all indicies. However non of them uses it yet 2015-09-23 14:38:23 +02:00
Michael Hackstein 73077a17fc Implemented the foundation to identify indicies based on DNF Conditions. Primary is implemented as an example. Right now it is only printed that it can be used. TODO: actually use it. Other indicies 2015-09-22 15:39:07 +02:00
Jan Steemann 8b599b5274 changed some include headers around 2015-09-07 17:09:10 +02:00

Michael Hackstein 8e3e2d547d Do not push <Class const> into vector. It does not work everywhere 2015-08-17 12:43:11 +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
