Query plans without namespace bindings?
by Hans-Juergen Rennau 08 Mar '16

08 Mar '16

Dear BaseX team, the fabulous query plans delivered by xquery:parse and xquery-parse-uri reference functions with their lexical names, but do not contain the namespace bindings,e.g.: <StaticFuncCall name="i:writeNameFilter" tailCall="false"> <VarRef> <Var name="$deprecate" id="652"/> </VarRef> </StaticFuncCall> It seems to me that using this tool for the analysis of dependencies (e.g. "which modules require function f:foo?", "in which module do I find the definition of function f:bar?"), the namespace bindings would be required. And such analysis would certainly be very useful, especially when dealing with large applications and code bases. What do you think? Cheers,Hans-Jürgen

Run tests / standards compliance
by Maximilian Gärber 07 Mar '16

07 Mar '16

Hi all, do you have an overview about the tests you typically run for a release? I know there are unit tests but there is also a basex-tests repo which contains other types of tests. The readme says some tests are 'broken' so how to know which ones are good? Regards, Max

Export database to SQL?
by Bhander, Gurbakhash S. 03 Mar '16

03 Mar '16

Hi, Is there any way to export data from the database to other databases? Thanks -Raj From: basex-talk-bounces(a)mailman.uni-konstanz.de [mailto:basex-talk-bounces@mailman.uni-konstanz.de] On Behalf Of Klavs Prieditis Sent: Wednesday, March 02, 2016 11:21 AM To: Christian Grün <christian.gruen(a)gmail.com>; Dirk Kirsten <dk(a)basex.org> Cc: BaseX <basex-talk(a)mailman.uni-konstanz.de> Subject: Re: [basex-talk] Parallel execution Hi, Thanks Dirk and Christian! My apologies for using such a strong word to describe such a minor issue. It is not my intention to underestimate your work. My main concern is that `async:fork-join()` is too heavy. I mean, in essence, I am solving the same problem in these two examples. ```xquery for $i in 1 to 10 return fetch:text("http://example.com/magic-story/for-number/" || $i) ``` ```xquery async:fork-join( for $i in 1 to 10 return function() {fetch:text("http://example.com/magic-story/for-number/" || $i)} ) ``` If you solve the same problem in Java 8 using Streams API you get the following two solutions. ```java rangeFrom1To10AsList.stream().map(fetchText).collect(...); ``` ```java rangeFrom1To10AsList.parallelStream().map(fetchText).collect(...); ``` Considering these two Java 8 solutions, I guess what I actually want is the `async` keyword. So that the second Java example could be rewritten as follows. ```xquery for async $i in 1 to 10 return fetch:text("http://example.com/magic-story/for-number/" || $i) ``` Problem here is that you need to introduce a new keyword to the language. I am just trying to figure out if there could be a solution like this. ```xquery for $i in 1 to 10 return fetch:text-with-implicit-parallel-execution-characteristics("http://example.com/magic-story/for-number/" || $i) ``` Thanks for your input! Currently I lack in-depth knowledge on XQuery, I'll try to get a spare time to study the XQuery specification so that I am able reason about the various consequences. 2016-03-02 11:36 GMT+02:00 Christian Grün <christian.gruen(a)gmail.com<mailto:christian.gruen@gmail.com>>: Hi Klāvs, Dirk already gave some good reasons why implicit parallelization is not the default in BaseX, although it may seems to be the most natural and desirable choice. Indeed it’s fairly easy to create FLWOR expressions which are slower when executed in parallel. The XQuery specification, by the way, does not say anything about parallelization, so it’s completely up to the implementation to choose the most promising evaluation strategy. You asked if it was not possible to introduce sth. like a `can-be-optimized-for-parallel-execution` flag, and you may be interested to hear that we had some first thoughts on an 'async' keyword, which could be used in FLWOR expressions [1]. In the GitHub issue, only the most basic cases have been considered so far, but if we manage to push this further, we would have a syntax that will be more easily accessible to most users. Ideally, some time in future, we could then apply this pattern automatically if it will be absolutely clear that parallelization leads to faster results. Everyone: If you notice that the async:fork-join function makes your code faster, don’t hesitate and send us your queries.

Import module with xquery:eval() function
by Ioan Fericel 03 Mar '16

03 Mar '16

Hi, I try to import a module dynamically, as in this example from a earlier discussion: > let $s:='import module namespace p="xquery-30" at "../repotest/test.xqm"; > p:parse-XQuery("2+2")' > return xquery:eval($s) It gives me the following error: > . . . [XQST0059] Could not retrieve module '/home/repotest/test.xqm'. I run BaseX 8.3 as war in Tomcat container. If the module is imported in static way: > import module namespace p = "xquery-30 " at "../repotest/test.xqm"; everything works correctly. From where does the problem with malformed relative path, what solution could be found? Thanks, Ioan
