[experr:HC0001] unknown protocol: localhost (Windows only)
by France Baril 21 May '19

21 May '19

Hi, We have two servers with similar jetty configuration, we find that an http:request call on static works on Linux but not on Windows. HOW TO REPLICATE Add an image test.png in webapp/static Try the attached .xqm (change img-url for your server path) Copy of the .xqm function for reference: declare %rest:path('/a-test') > %rest:GET > %output:method("html") > %output:html-version("5.0") > function a-test:http-req(){ > let $img-url := 'http://localhost:8972/static/test.png' > let $http-function := function() {http:send-request(<http:request > method='get' status-only='true'/>, $img-url)} > let $http-s := xquery:fork-join($http-function) > let $http-status := $http-s//data(@status) > return <div>{$http-status}</div> > }; Test: http://localhost:8972/a-test Result on Linux: 200 Result on Windows: [experr:HC0001] unknown protocol: localhost This seemed to be security issue, but tests in multiple browsers return the same results and enabling CORS doesn't help... technically we're calling from the same domain/port... but hey we tried! If we type the value of $img-url directly in the browser, we see the image on both platforms, so the issue is not with accessing the image itself, but with accessing it with the http:send-request function. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

db:replace() in DBA resulting in duplicates
by Zimmel, Daniel 20 May '19

20 May '19

Hello, something has gone awry in my database after a db:replace(): query: db:open('DB','/path/file.xml')/base-uri() result: /DB/path/file.xml This is as expected. The result is the replaced file. But when I query: db:open('DB')/root[@id='id']/base-uri() result is a sequence: /DB/path/file.xml /DB/path/file.xml The first result is the file before the db:replace(), the second after. Can somebody explain why db:open() with path parameter is returning one result, but without parameter two results? Database statistics say there are indeed two documents. But when I export the database, only one gets exported. This happens with db:replace() on 9.2 from the DBA browser interface. When I use the same db:replace() XQuery on 9.2 with my local database, all is well (document gets replaced, no duplicates). Settings should be the default ones. Thanks, Daniel

Hi, at http://docs.basex.org/wiki/Database_Module there is a typo for the signature of 'db:attribute#3': It's 'xs:strings' instead of 'xs:string'. *db:attribute*($db as xs:string, $strings as xs:strings*, $name as xs:string) as attribute()* -- Minden jót, all the best, Alles Gute, Andreas Mixich

Hi is it possible to run multiple testsuites with one TEST command call from the basex console? Or is there always only one <testsuite> element in the <testsuites> result? Markus __________________________________________

Optimizer and JSON/XML response
by Marco Lettere 17 May '19

17 May '19

Hello everyone, we came accross an inconsistency which we are not able to find an explanation for and giving up after having spent on it the whole morning... From a restxq we call an external REST service (InfluxDB) like shown in [1]. This usually works as expected returning a response forged as in [2]. When the same RESTXQ is deployed in a much more complex application (with several RESTXQ modules and REPO modules) the first call (which takes a lot of time because it incurs the initial compiling delay) returns [3] instead of [2]. From the second call onwards the result stabilizes correctly to [2]. If I call any other RESTXQ function as a sort of warm-up (spending there all the initial delay) [1] behaves correctly returning always [2]. Do you please have a clue on why this happens? We noticed it for the first time because we started to use service jobs which cause this access pattern ... Thanks for any help. [1] module namespace test = 'test'; declare %rest:path("test") %rest:GET function test:test() { let $url := "http://localhost:8086/query?pretty=false&chunked=false&db=nestway&a…" let $results := http:send-request(<http:request method="get"/>, $url) return $results }; [2] <http:response xmlns:http="http://expath.org/ns/http-client" status="200" message="OK"> <http:header name="Transfer-Encoding" value="chunked"/> <http:header name="Connection" value="close"/> <http:header name="X-Influxdb-Version" value="1.1.1"/> <http:header name="Date" value="Thu, 16 May 2019 11:05:59 GMT"/> <http:header name="Request-Id" value="95b729c7-77ca-11e9-8065-000000000000"/> <http:header name="Content-Type" value="application/json"/> <http:body media-type="application/json"/> </http:response> <json type="object"> <results type="array"> <_ type="object"> <series type="array"> <_ type="object"> <name>frontoffice</name> <columns type="array"> <_>time</_> <_>consumable</_> <_>customer</_> <_>guests</_> <_>type</_> <_>user</_> </columns> <values type="array"> <_ type="array"> <_>2019-05-10T21:55:00Z</_> <_>access</_> <_>c9a83ce3-c938-4677-a0df-72bc96354509</_> <_ type="number">0</_> <_>starttimer</_> <_>d50de945-23ed-4b33-84e8-8ef533a96fb7</_> </_> </values> </_> </series> </_> </results> </json> [3] <http:response xmlns:http="http://expath.org/ns/http-client" status="200" message="OK"> <http:header name="Transfer-Encoding" value="chunked"/> <http:header name="Connection" value="close"/> <http:header name="X-Influxdb-Version" value="1.1.1"/> <http:header name="Date" value="Thu, 16 May 2019 11:19:30 GMT"/> <http:header name="Request-Id" value="7957030a-77cc-11e9-8066-000000000000"/> <http:header name="Content-Type" value="application/json"/> <http:body media-type="application/json"/> </http:response> map { "results": [map { "series": [map { "values": [["2019-05-10T21:55:00Z", "access", "c9a83ce3-c938-4677-a0df-72bc96354509", 0.0e0, "starttimer", "d50de945-23ed-4b33-84e8-8ef533a96fb7"]], "name": "frontoffice", "columns": ["time", "consumable", "customer", "guests", "type", "user"] }] }] }

Database lock during RESTXQ operation
by Martin Iggulden 17 May '19

17 May '19

We just encountered a stuck lock on a BaseX database. It was during repeated calls to a RESTXQ operation that modifies the database. The operations were working OK, then one returned an error: [db:lock] Database 'd7c552cc-1f5e-47dc-ba91-37054695aabf' is currently opened by another process. This error then appeared for any further attempt to update the database, and persisted for several days (although it seems to have cleared now). It's possible that two updates were being processed concurrently, but they would have been processed by the same Java VM because the RESTXQ server is the only active interface to the database. We have seen this error before, but it's difficult to reproduce. Do you know how this might have happened? And is there a procedure for clearing down an erroneous database lock if it happens? We are running BaseX version 9.1.2.

Extracting function signatures from documentation
by Andreas Mixich 16 May '19

16 May '19

Hi, I am doing some tooling for XQuery and need to extract function signatures from text, like from the BaseX module library documentation. But with my regex skills I just hit the wall. Next step would be to write some complex program, that does the parsing, maybe in combination with regexes, but before I start into that, I wanted to ask, whether the work has already been done. Is there a marked up version of the BaseX function docs? Or, even better (since I could apply it to other docs, then) does anyone know of a regular expression or an XQuery routine, that analyzes function signatures? Thanks a lot! -- Minden jót, all the best, Alles Gute, Andreas Mixich

Hi Loren, So far I haven’t. Where do I find it? Does it also contains the BaseX functions, or the standard W3 function set?

inspect:functions#1 on XPath funcs errors out with [XPST0003] and returns an XHTML file
by Andreas Mixich 16 May '19

16 May '19

Hi, opening a new sheet in the GUI I just executed: inspect:functions("http://www.w3.org/2005/xpath-functions") and this is what I got: Error: Stopped at http://www.w3.org/2005/xpath-functions, 1/6: [XPST0003] Processing instruction has illegal name: xml. Optimized Query: inspect:functions("http://www.w3.org/2005/xpath-functions") The Query itself is, as returned by BaseX, interestingly, an XHTML file, which seems to have been produced via Saxon, here are the first lines: <?xml version="1.0" encoding="UTF-8"?>  <html xmlns="http://www.w3.org/1999/xhtml" lang="EN"> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"/> <title>XQuery, XPath, and XSLT Functions and Operators Namespace Document </title> <meta name="viewport" content="width=device-width, initial-scale=1, shrink-to-fit=no"/> <style type="text/css"> </style> <link rel="stylesheet" type="text/css" href=" http://www.w3.org/StyleSheets/TR/base.css"/> </head> <body> <div class="head"> <p> <a href="http://www.w3.org/"> <img src="http://www.w3.org/Icons/w3c_home" alt="W3C" height="48" width="72"/> </a> </p> <h1><a name="title" id="title"/>XQuery, XPath, and XSLT Functions and Operators Namespace Document </h1> <h2>21 March 2017</h2> </div> <nav id="toc"> <h2><a id="contents"/>Table of Contents </h2> <ol class="toc"> <li> <a href="#intro"> <span class="secno">1 </span> <span class="content">Introduction</span> </a> <ol class="toc"/> </li> And here is the QueryPlan: Query Plan: <QueryPlan compiled="true" updating="false"> <InspectFunctions name="inspect:functions" type="(function(*))*"> <Str type="xs:string" size="1">http://www.w3.org/2005/xpath-functions </Str> </InspectFunctions> </QueryPlan> -- Minden jót, all the best, Alles Gute, Andreas Mixich

Change data directory for basex & BaseXGUI
by Majewski, Steven Dennis (sdm7g) 16 May '19

16 May '19

I’ve been learning and testing basex with the default MacOS home-brew installation. For production, I’m planning on using the war file served using tomcat. I would like to use the basex command line client and BaseXGUI to do some initial setup and testing on the tomcat web app databases. Is there a java property setting or other way to set the data directory location for these programs ? Or do I have to set these paths in ~/basex/.basex file . The latter is not ideal, as I may need to run update scripts from different user cron jobs, so I’ld rather not depend on home directory. — Steve Majewski
