BaseX performance 7.x vs 8.x
by Bondeson, Carl 04 Aug '16

04 Aug '16

I am seeing huge differences in the performance of a multi-threaded JBoss application recently upgraded from 7.9 to 8.4. The problem is that 8.4 is much slower than 7.9. Any ideas? Do I need to add indices or something along those lines?

Inconsistency of regular expression support in BaseX and GUI
by Kristian Kankainen 03 Aug '16

03 Aug '16

Hello! Today I noticed that I can successfully use the following regular expression inside XQuery but the same regexp fails when using it in the GUI's searchboxes (the ones appearing when pressing Ctrl+F) when enabling regular expression search. This is the regular expression and probably it is the block escape that is causing the error: (¹|²|³|\p{IsSuperscriptsandSubscripts}) The error message says: "Regular Expression: java.util.regex.PatternSyntaxException: Unknown character property name {issuperscriptsandsubscripts} near index 37" Probably the lowercaseing of the block escape name is causing the error and hopefully it can be fixed without too complex logics. Best regards Kristian K

Error report in baseX-dev

Hi, I'm trying to delete some files that I just added to my db To give context, I originally added them via Oxygen data source explorer baseXdev, but I am trying to delete them in the dba https://basex-dev.eos.arz.oeaw.ac.at/dba/database?name=dboe-xml and the error 500 message below is what occurs. The uploading process originally stopped and gave an error message and listed about 4 files that would not be included in upload but the rest appeared but now nothing else can be added or deleted.

users.xml change outside basex
by Maximilian Gärber 02 Aug '16

02 Aug '16

Hi, it seems all of users.xml will be rewritten on changes. I just tried to add a <groups> element next to <users>. Any way to preserve changes in the users.xml ? Maybe allow for a <custom> section or similar? By the way: what was the reason users.xml is not stored as a basex database but on the file system? Regards, Max

db:optimize questions
by Baysdon, Joseph 02 Aug '16

02 Aug '16

I a new baseX user and I have a few questions regarding the db:optimize command. Does 'optimize all' perform all available optimizations or are there other parameters (indexing or full-text as mentioned at http://docs.basex.org/wiki/Database_Module#db:optimize) to supply? Is read/write possible to a database undergoing optimization? I’m guessing no because I get an error (“Database ‘foo’ is currently opened by another process”) whenever another connection to the database is open. On what size or content of databases does optimization have a significant impact? Currently on a 400Mb database, I don't see any performance benefits after optimization. (Note: all of my performance testing is using a simple db:list command.) Thanks in advance for any assistance you can provide. Joe

Non-Admin user and db:system()//repopath
by Maximilian Gärber 01 Aug '16

01 Aug '16

Hi, this returns nothing (as non-admin), but I noticed you can still list any folders above. In my case the empty string left to having a path with a single slash '/' which translated to the root of the drive that basex was installed. I got the complete contents of the drive with our query [1]. The way it is right now, I see no reason why db:system()//repopath returns nothing.

Re: [basex-talk] Validating with XML schema
by Christian Grün 31 Jul '16

Hi Chahd (cc to the list), > Can I do it with the Rest service? Yes you can [1]: http://localhost:8984/rest/MyFirstBase/text.xml?query=validate:xsd(., db:open('MyFirstBase/text.xml')) I agree this doesn’t look very straightforward. If you are interested in spending some more time with XQuery, you could use RESTXQ [2] to provide more intuitive URLs. An example: Your URI: http://localhost:8984/restxq/validate/text.xml?schema=validate:xsd Your server-side RESTXQ code (see the documentation and the example in the zip/exe distributions for more details): declare %rest:path('/validate/{$doc}') %rest:query-param('schema', '{$schema}') function local:validate($doc, $schema) { let $db := 'MyFirstBase' return validate:xsd(db:open($db, $doc), db:open($db, $schema)) }; Christian [1] http://docs.basex.org/wiki/REST#GET_Method [2] http://docs.basex.org/wiki/RESTXQ On Sat, Jul 30, 2016 at 11:41 PM, Chahd Chahd <chahd.chahddd(a)gmail.com> wrote: > > 2016-07-30 22:24 GMT+02:00 Christian Grün <christian.gruen(a)gmail.com>: >> >> Hi Chahd, >> >> > I am using the web application of BaseX.

Hi, I am using the Database Administration interface. I created a base named "MyFirstBase" and I add 2 resources (test.xml and test.xsd). How can I write the paths of the resources properly in a query? I tried: validate:xsd('test.xml', 'test.xsd') but I have a *[FODC0002] Resource 'test.xml' does not exist.* *Thank you*

BaseX and Oxygen
by Marc van Grootel 28 Jul '16

28 Jul '16

Hi all, (sorry if this is too much off-topic) I re-read some of the related topics on this list. I have also installed the Argon plugin (very nice). I tried this several times in the past but everytime I went back to the BaseX gui. But I would like to be able to reduce my use of the BaseX gui and do more directly from Oxygen. Even though the gui is very nice I would like to more development to be done from Oxygen. I wanted to post here first as you all may have some ideas on how to fix some shortcomings to the current BaseX/XQuery workflow with Oxygen. When I have a better idea of what is really missing or can't be worked around I will also post some of these things on the Oxygen list. 1) Syntax Although I understand that XQuery 3.1 wasn't official with the release of 17.1 earlier versions were a bit more relaxed about syntax. Instead in 17 and higher whenever XQuery code uses typical 3.1 syntax (such as literal arrays) syntax coloring displays parts of the code in red. Earlier versions, if I remember correctly, I believe did a better job at this. Is there a way to avoid having large parts of the code in red (I tend to use arrays and other 3.1 syntax quite a lot). 2) Validating It seems that, even if I choose the BaseX connection for validation, the code still gets analyzed by Saxon 9.6 which doesn't know about the 3.1-isms and barfs with: E [BaseX - Localhost] Invalid XQuery syntax, syntax does not pass static validation. I guess that's Saxon talking here. That's it really, quite basic. Feels like it's almost, but not quite, there yet. Any tips? I will post to Oxygen mailing list once I am convinced that I have done everything I can to improve the situation. --Marc

Hi, I keep getting an error message in Basex GUI saying Error: Stopped at D:/XML/xquery/GBF-RekExt-Nr_v22_basex-CSV-withDB-toDisk.xq, 10/2: [XPTY0004] xs:double expected, empty sequence found.

db:store question
by Wang, Genneva 28 Jul '16

Hi basex guru’s, I’m wondering if there are other mechanisms to add binary resources other than using db:store? We are using java client, hence we are using the store method. We are currently experiencing some performance issue with only this method call, so was wondering if there are other alternatives. Any tips would be greatly appreciated. Thanks. Regards, -Genneva

I have log4j at trace level and the server is started but when a call is made to the ClientSession constructor nothing happens. static final int BASEX_SERVER_PORT = 1990; static final String BASEX_USER = "admin"; static final String BASEX_PASSWORD = "admin"; static final String BASEX_HOST = "localhost"; try { // get server status boolean serverstarted = BaseXServer.ping(BASEX_HOST, BASEX_SERVER_PORT); // server started? if (!serverstarted) { instance.basexlog.trace("BaseXDictionary: BaseX: Start BaseX server"); // no-> create a new instance using server and client ports // BaseXServer server = new BaseXServer("-p" + BASEX_SERVER_PORT); } else { // yes-> log the event instance.basexlog.trace("BaseXDictionary: BaseX: BaseX server already started"); } // start initialization process instance.basexlog.debug("BaseXDictionary: BaseX: Server started"); // this call never returns or something strange is going on instance.mapperDBSession = new ClientSession(BaseXDictionary.BASEX_HOST, BaseXDictionary.BASEX_SERVER_PORT, BaseXDictionary.BASEX_USER, BaseXDictionary.BASEX_PASSWORD); This next log4j output is never seen in the log file instance.basexlog.trace("BaseXDictionary: BaseX: Client Session created "); Any JBoss users?

Changes to wildcards in 8.5.2?
by France Baril 26 Jul '16

26 Jul '16

Hi, This query works with 8.5.1 when the value of $wild-words is *.*, but not in 8.5.2. It works in 8.5.2 for real text values, so the issue seems to be with the *.* expression: *let* *$search-result* := *if* (*$operator* = 'and') *then **$search-subset*[(descendant::*title*[1] *contains* *text* ({ *$wild-words*} *all* *using* *wildcards* *weight* {2})) or (. *contains* *text* ({*$wild-words*} *all* *using* *wildcards* *weight* {0.5}))] *else **$search-subset*[(descendant::*title*[1] *contains* *text* ({ *$wild-words*} *any* *using* *wildcards* *weight* {2})) or (. *contains* *text* ({*$wild-words*} *any* *using* *wildcards* *weight* {0.5}))] Not seeing info about changes at http://docs.basex.org/wiki/Full-Text . -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

discard-document equivalent
by George Sofianos 23 Jul '16

23 Jul '16

Hi again, I wonder if there is an equivalent command to discard-document which is available in Saxon PE? I have a list of XML documents available in a remote repository, and I make the same checks in every XML in a for loop. Example: let $list := ("http://url1", "http://url2", "http://url3", "http://url4") for $file in $list return local:runChecks(doc($file)) If the documents are large, they will keep filling the memory. I just run a script that uses 42 files about 50mb each, and that consumed over 2GB of memory. The checks are quite complex so I don't think that the fetch module would work here, if my understanding is correct about what it does. For more information about how discard-document works, see my question/answer on SO: http://stackoverflow.com/questions/34514859/using-discard-document-with-sax… Thanks!

Behaviour of db:open('mydb') update {} in updating functions
by Maximilian Gärber 22 Jul '16

22 Jul '16

Hi, I just noticed that when I use a db that is opened this way, I cannot do updates anymore. Example: declare variable $_:PUB := db:open('PUB') update {}; Then, inside updating function: let $sec := $_:PUB//Section[@Guid = $id] return replace node trace($sec) with <Section>changed</Section> There is no error whatsoever, the update simply doesnt happen. (BaseX 8.4.4) Bug? Regards, Max

Schema validation
by George Sofianos 22 Jul '16

22 Jul '16

Hi, I wonder what is the status of schema validation in BaseX? I have a Java web service that is used to validate some schemas, which is using xerces2 to validate XML files. I want to transfer some of this work to my XQuery scripts in BaseX, so I can minimize the bandwidth on large files (the XML files are being retrieved from a remote repository). I did try to put xercesImpl.java on the lib directory, the validation does run, but I'm not sure about these two things 1) Is the new version of xerces being used, or is the Java default one being used? Maybe it's possible to add a function to return the library being used? 2) My Java service (which is using xerces2) is running the validation in about 5 seconds, the same validation takes 32 seconds in BaseX 8.5.1 Any ideas, tips etc are welcome Thanks, George.

declare option db:chop 'no' not supported in 8.5.1 for .xqm files
by France Baril 21 Jul '16

21 Jul '16

Hi, I'm trying to migrate a project from 8.2.2 to 8.5.1. I'm this getting errors on all "declare option db:chop 'no';": [bxerr:BASX0010] Database option not allowed in library module: chop. Does it mean that I no longer need these to keep my spaces intact or is it a bug? I didn't find anything in the doc that mention this option being removed. I'm still finding the option in the doc with 'false' instead of 'no' at http://docs.basex.org/wiki/XQuery_Extensions, and with 'no' at: http://docs.basex.org/wiki/XSLT_Module. I tried changing 'no' to 'false', but it seems that the issue is with the option itself, not with the value. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Maximum number of hits
by George Sofianos 21 Jul '16

21 Jul '16

I have changed Maximum number of hits to All, but still, BaseX result gets chopped some times. Is this a bug or an intended behaviour? My only problem is that I run XQuery scripts that need 200+ seconds to finish, so whenever this happens when I click save, they will have to run again in the background. I know there is an alternative way to run them, (for example using file:write) but I can't really use it at the moment. My result is just 1 large <div> element, and the output method is HTML. Thanks, George.
