Applying indexes
by Menashè Eliezer 03 Aug '15

03 Aug '15

Hello, 1. In which cases the "applying index" phrase should I see in the query plan? I have an old query (the one I've sent here at 06/22/2015) where only for one condition I've seen "applying index", and even this one doesn't appear anymore using a newer (8.2.2) version of BaseX and a larger database. I do see the right properties of the db: Indexes Up-to-date: true TEXTINDEX: true ATTRINDEX: true 2. Only once a value which is mentioned in the query is found in the index, in case of "=" condition? 3. Always, in case of "<" or "<" condition, assuming the specific text/attribute has been indexed? 4. Everything I see as a reply to index:facets is indexed, right? -- With kind regards, Menashè

Hello, I don't know why I don't see anymore query log events like "admin OK QUERY" in the .logs folder. Not even when I use the -d flag. BaseX 8.2.2 -- With kind regards, Menashè

compiling and building basex-core with maven
by Rob Stapper 03 Aug '15

03 Aug '15

Hi Christian, I'm trying to compile and build the basex-core. All is going quit well except that one testrun is failing which results in not being able to build the basex-core. I started the process from within the basex-core-directory with the command: mvn -U clean install. After a zillion test almost as last the "org.basex.server.LockingTest" fails with the message: java.lang.AssertionError: Parallel execution expected at org.junit.Assert.fail<Assert.java:88> at org.junit.Assert.assertTrue<Assert.java:41> at org.junit.Assert.LockingTest.testQueries<LockingTest.java:125> at org.junit.Assert.LockingTest. LockingTest.<LockingTest.java:146> I'm running on a simple windows-system with windows vista home edition. No apache-serve running. Can you give me a hint to get the basex-core build? TIA. Rob PS. maven on Basex-test also give problems but basex-api and basex-examples works fine. --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. https://www.avast.com/antivirus

Returning REST Response From Updating Function
by Eliot Kimber 02 Aug '15

02 Aug '15

I'm trying to understand how to use db:output() in the context of a REST function that does a bunch of stuff that updates and then wants to return a result. I have my updating functions using db:output() to return XML elements that are log entries, which I have up to now then formatted as HTML for return by the Web app. However, there doesn't appear to be a way to get the stuff returned by db:output before it gets returned to the ultimate caller. Have I missed something? My REST-handling function is declared as %updating: declare %updating %rest:path("/repo/{$repo}/{$branch}/updateLinkManagementIndexes") Which I understand to be a requirement if the function itself calls any updating functions. I tried e.g.: let $result := f:myUpdatingFunction() return db:output(f:formatLogItems($result)) But that results in the "no updating functions" message on the variable assignment. Is there a way to do what I want? Thanks, Eliot ---- Eliot Kimber, Owner Contrext, LLC http://contrext.com

RESTXQ: Call a Page With A Parameter That Does not Persist in the URL
by Eliot Kimber 01 Aug '15

01 Aug '15

In the context of my RESTXQ Web service that uses web:redirect, when the process is done I want to return to the original page and on that page display a message indicating that the process succeeded or failed. My initial attempt was simply to redirect to the page and use a query parameter to convey the message. The REST handler then checks for the message and if present shows it in the generated page. The problem I'm running into is that the query parameter persists in the URL so if the user refreshes the page the message is still there, even though it's no longer relevant. There must be a way to do what I want but I'm not sure what it is. Based on my research I think I can do a form POST instead of a GET but that seems kind of heavy weight. Is there a simpler/better way to achieve this effect? I didn't see anything obvious in the RESTXQ docs. Thanks, Eliot ---- Eliot Kimber, Owner Contrext, LLC http://contrext.com

Unknown error - BXCE001
by Gabriel Tessarolli 30 Jul '15

30 Jul '15

Hi, I've been struggling with this error for quite a while now and still don't have a clue why it is raised. Caused by: javax.xml.xquery.XQException: BXCE001 - at net.xqj.basex.bin.b.<init>(Unknown Source) at net.xqj.basex.bin.a.a(Unknown Source) at net.xqj.basex.bin.d.a(Unknown Source) at net.xqj.basex.bin.E.a(Unknown Source) at net.xqj.basex.bin.H.executeQuery(Unknown Source) There is no text description for this. First I thought it was something related to memory, but now I don't think this is the reason. As you can see, I am using BaseX XQJ, and it is version 1.4. BaseX is 8.1. It seems that my application receives this exception a little bit (4 seconds) before server tries to send the response back. This is what I get from server side: 15:29:20.050 127.0.0.1:49514 admin REQUEST FULL[0] 5727205.52 ms 15:29:20.050 127.0.0.1:49514 admin ERROR Can't communicate with the server. 0.12 ms It is a complex query, and it takes a while to respond. Is there any place I can get a better description on this BXCE001 exception? I couldn't find any. Thank you in advance! Best Regards, Gabriel

Query plan: long printing
by Menashè Eliezer 30 Jul '15

30 Jul '15

Hello, I have a query which is quite fast, but I see in the query plan (Using the client GUI) that the printing is very very slow, even when the number of hits is zero. I wonder what it means, and it is a problem. I'm sending these messages in different posts for helping users find this information. -- With kind regards, Menashè

Getting More Diagnostic Info From DBA Query Runner?
by Eliot Kimber 28 Jul '15

28 Jul '15

I'm using the DBA web app to test and debug my Web app and underlying queries. However, when there are runtime errors it only reports the error, but not the code that produced it. Is there any way for the query runner to report what module/function/line the error resulted from? Or is that information in a log somewhere?

RESTXQ: wrong doctype with xhtml method
by Maximilian Gärber 28 Jul '15

28 Jul '15

Hi, when using 'xhtml' output method, the doctype always matches the name of the root element (instead of 'html'). Does not happen with 'html' output method. -- start xqm -- declare %rest:GET %rest:path("test-frag") %output:method("xhtml") %output:html-version("5.0") function _:test-frag(){ <form> </form> }; -- end xqm -- Result: <!DOCTYPE form> <form></form> Regards, Max
