We have released a maintenance release of ArangoDB 1.4. 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. You can download it from https://test.arangodb.com/download or use your package manager.

v1.4.14 (2014-04-05)

• fixed race conditions during shape / attribute insertion A race condition could have led to spurios `cannot find attribute #xx` or `cannot find shape #xx` (where xx is a number) warning messages being logged by the server. This happened when a new attribute was inserted and at the same time was queried by another thread. Also fixed a race condition that may have occurred when a thread tried to access the shapes / attributes hash tables while they were resized. In this cases, the shape / attribute may have been hashed to a wrong slot.
• fixed a memory barrier / cpu synchronisation problem with libev, affecting Windows with Visual Studio 2013 (probably earlier versions are affected, too) The issue is described in detail here: http://lists.schmorp.de/pipermail/libev/2014q1/002318.html

v1.4.9 (2014-02-07) ——————- * return a document’s current etag in response header for HTTP HEAD requests on documents that return an HTTP 412 (precondition failed) error. This allows retrieving the document’s current revision easily. * added AQL function `SKIPLIST` to directly access skiplist indexes from AQL This is a shortcut method to use a skiplist index for retrieving specific documents in indexed order. The function capability is rather limited, but it may be used for several cases to speed up queries. The documents are returned in index order if only one condition is used. /* return all documents with mycollection.created > 12345678 */ FOR doc IN SKIPLIST(mycollection, { created: [[ ‘>’, 12345678 ]] }) RETURN doc /* return first document with mycollection.created > 12345678 */ FOR doc IN SKIPLIST(mycollection, { created: [[ ‘>’, 12345678 ]] }, 0, 1) RETURN doc /* return all documents with mycollection.created between 12345678 and 123456790 */ FOR doc IN SKIPLIST(mycollection, { created: [[ ‘>’, 12345678 ], [ ‘<=’, 123456790 ]] }) RETURN doc /* return all documents with mycollection.a equal 1 and .b equal 2 */ FOR doc IN SKIPLIST(mycollection, { a: [[ ‘==’, 1 ]], b: [[ ‘==’, 2 ]] }) RETURN doc The function requires a skiplist index with the exact same attributes to be present on the specified colelction. All attributes present in the skiplist index must be specified in the conditions specified for the `SKIPLIST` function. Attribute declaration order is important, too: attributes must be specified in the same order in the condition as they have been declared in the skiplist index. * added command-line option `–server.disable-authentication-unix-sockets` with this option, authentication can be disabled for all requests coming in via UNIX domain sockets, enabling clients located on the same host as the ArangoDB server to connect without authentication. Other connections (e.g. TCP/IP) are not affected by this option. The default value for this option is `false`. Note: this option is only supported on platforms that support Unix domain sockets. * fail if invalid `strategy`, `order` or `itemOrder` attribute values are passed to the AQL TRAVERSAL function. Omitting these attributes is not considered an error, but specifying an invalid value for any of these attributes will make an AQL query fail. * call global arangod instance destructor on shutdown * issue #755: TRAVERSAL does not use strategy, order and itemOrder options these options were not honored when configuring a traversal via the AQL TRAVERSAL function. Now, these options are used if specified. * allow vertex and edge filtering with user-defined functions in TRAVERSAL, TRAVERSAL_TREE and SHORTEST_PATH AQL functions: // using user-defined AQL functions for edge and vertex filtering RETURN TRAVERSAL(friends, friendrelations, “friends/john”, “outbound”, { followEdges: “myfunctions::checkedge”, filterVertices: “myfunctions::checkvertex” }) // using the following custom filter functions var aqlfunctions = require(“org/arangodb/aql/functions”); aqlfunctions.register(“myfunctions::checkedge”, function (config, vertex, edge, path) { return (edge.type !== ‘dislikes’); // don’t follow these edges }, false); aqlfunctions.register(“myfunctions::checkvertex”, function (config, vertex, path) { if (vertex.isDeleted || ! vertex.isActive) { return [ “prune”, “exclude” ]; // exclude these and don’t follow them } return [ ]; // include everything else }, false); * issue #748: add vertex filtering to AQL’s TRAVERSAL[_TREE]() function
