Re: [basex-talk] Java Heap Space Error
by Dirk Kirsten 29 Dec '12

29 Dec '12

Dear John, should work as well on the mailing list, so I am answering on the list. Maybe someone else can benefit from your question as well. For an OutOfMemoryException I would always simply try to increase the Java Heap space using the -Xmx option starting BaseX. if this is not helping, maybe some bug was introduced in a newer version. To check this we need a simple self-contained example, i.e. a simple query and some data to demonstrate the problem.

RFE: Turning off parts of the BaseX REST interface
by C. M. Sperberg-McQueen 22 Dec '12

22 Dec '12

I am building some Web-based services for a project I'm involved with, using the BaseX REST interface, and the experience has given me an idea for a possible enhancement to BaseX. It's extremely convenient for development to be able to issue arbitrary queries from the REST interface, but in my role as part-time system administrator and worrier about security, the REST 'query', 'command', and 'get' operations worry me to death. I am happy for the user access control provided by the GRANT command, and I find myself thinking it would be even nicer to have more control. I am happy to discover by experiment that a user with READ access only to a single database sees only that database name when they issue the the default GET request (http://hostname:8984/rest). When I allow my security paranoia full sway, I find I would like to be able to ensure that only authorized users can - perform arbitrary queries using the 'query' or 'command' interfaces - perform particular queries using the 'run' interface Concretely, in this case I would like to be able to create a user for restricted access, which I'll call PUBLIC for now, and ensure that a user who presents the PUBLIC userid and password - cannot fetch any data using the GET interface - cannot run queries using the rest:query interface - cannot run commands using the rest:command interface - can run only specified modules from the HTTPPATH directory (so we can limit the portions of the database we expose to the PUBLIC user -- I think of this as very roughly analogous to being able to limit a SQL user to particular views instead of to the underlying base tables) Of course, by running a packet filter we can ensure that the BaseX server only receives packets from (or: purporting to be from) the project's host, and we can keep the user password for the PUBLIC user secret in what I believe is the usual way (it's there in the source of the PHP module, but web users don't get to see the source of the module). The restrictions I have in mind would serve the purpose of attempting to limit the damage an adversarial user could cause if the user credentials were exposed or (in the case of limiting users to specific modules) if an adversary were able to add modules to the HTTPPATH directory. Disclaimer: I am not a security expert, just (at the moment) a worrier. You will surely be able to get advice from people who understand security issues better than I do. Thank you again for this extremely helpful software. -- **************************************************************** * C. M.

basex SERVERHOST
by Liam R E Quin 22 Dec '12

22 Dec '12

How do I use SERVERHOST in ~/.basex (or elsewhere) to get basex to listen on the given PORT only on localhost (127.0.0.1) and not on externally-visible IP addresses? Setting SERVERHOST and HOST to localhost does not seem to accomplish this.

server / GUI synchronization and data safety
by C. M. Sperberg-McQueen 22 Dec '12

22 Dec '12

At various points in the documentation, it is observed that the BaseX server, the BaseX client, and the GUI interface all run in different virtual machines, so the GUI and the server's databases are not synchronized. In the GUI of BaseX 7.3, I see an optional Server Administration on the Database menu, which carries the warning Warning: The client/server architecture and the GUI are not synchronized. The same database should not be opened from clients and the GUI. Does this mean that it's safe to run both the server and the GUI as long as they have different databases open? (It doesn't say that; it says it's unsafe if they have the *same* database open. You see how timid warnings can make a user!) Also - in my case it would be convenient to be able to open the GUI and do some work while the BaseX HTTP server is running. If the HTTP server handles a request directed at database X, does that database remain open indefinitely or is it closed when the request has been handled? That is, is it safe to work with database X as long as I don't pass requests against X to the HTTP server at the same time/ And third - if neither the HTTP server nor the GUI are performing any updates, but only retrievals from the database, does the warning still apply, or is read-only access from multiple instances of BaseX actually safe? (I ask because if I need to shut down the HTTP server every time I want to launch the GUI to experiment with a new function, and then shut down the GUI so I can launch the HTTP server and work on the Web interface to the new function, then I am going to want to find a more convenient way of starting and stopping the HTTP server than going into a terminal window and running the shell script.)

Spatial XQuery
by David Stuebe 21 Dec '12

21 Dec '12

Hi Basex-ers I am new to the list but have been working with basex for a few weeks now. We are using basex to search ISO 19115 geospatial metadata. The full text search is simple and works better than any of the existing purpose built catalog tools we have worked with so far. I am very interested in the pervious thread on Spatial Xquery. https://mailman.uni-konstanz.de/pipermail/basex-talk/2012-January/002484.ht… I am looking over the Geo Module geospatial API<http://expath.org/spec/geo> today, and also at Zorba's Geo Module<http://www.zorba-xquery.com/html/modules/expath/geo> implementation. Has the Basex community made an further progress? The API is the first issue and so far the Geo Module definition looks great. If linear search using the existing attribute indexes is all that is available now, that is fine. It would be fantastic to write a geo spatial index to support that API in basex in the future. What type of indexes have you considered? I would think an Rtree would probably be best for supporting that API. This email is essentially a status query – as I work on this over the next week or two we can start new threads for specific topics.

Restxq updating functions running indefinitely.
by France Baril 19 Dec '12

19 Dec '12

Hi, I just upgraded to 7.5 from 7.4. Everything seems to work except the Updating functions db:replace and db:store (I use db:add elsewhere and it works as it did before). There is very little information regarding what the problem could be: - I am starting the httpserver with these .basex settings: USER = admin and PASS = admin. So I do not expect the problem to be security. - Symtom: the query runs and never times out. Browser stays on empty page. I have to stop the server with the httpstop script. - Error messages in the terminal window: None. - When I start the server I get this message before the server starts: Null identity service, trying login service: null Finding identity service: null I tried two different 7.5 snapshots including today's RC1. Any clue is welcome. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

DTD validation
by France Baril 18 Dec '12

18 Dec '12

Hi, We are having challenges with validation. We have built a Documentation Controller for authors that create XML content. On a regular basis, we ask them to check that all documents are valid. We are running the process on hundreds of file. the ideal situation would be to collect all errors and display them of the webpage for authors to find and correct. Ex. of dream code: *let **$db* := *app:open-db*(*$lang*) *let* *$topic-validation* := <ul>{*for **$x* *in **$db*/*[* name*()='topic' or *name*()='media'] *return if* (*contains*(* validate:dtd*(*$x*, *$app:dtd-topic*), 'BXVA0001')) *then *<li>File {*$x*/* base-uri*()} doesn't validate against the DTD.</li> *else *() } </ul> *let* *$menu-validation* := <ul>{*for **$x* *in **$db*/*[* name*()='menu'] *return if* (*contains*(* validate:dtd*(*$x*, *$app:dtd-menu*), 'BXVA0001')) *then *<li>File {*$x*/* base-uri*()} doesn't validate against the DTD.</li> *else *() }</ul> *return if* (*count*(*$topic-validation*/*li*) + *count*(* $menu-validation*/*li*[*normalize-space*(.) != '']) != 0) *then *<div>{*$topic-validation*}{*$menu-validation*} </div> *else *<ul><li *style*=*"color:green"*>All menus and topics validate against the DTDs.</li></ul> Instead, as soon as validate:dtd finds one single file with an error, it crashes the web page with an error message like this: Stopped at line 270, column 77 in /Applications/basex75/webapp/restxq/How2_Admin.xqm: [BXVA0001] Validation failed: 1355790115420.xml, 3:22: Element type "headin" must be declared. On top of this, the name of the file that is referenced in the error message doesn't exist. I've been querying the DB to find errors. Ex. Search for all files with 'headin' in this case. However, we'd really like the writer to be able to find their own faulty files. Are we misusing the function? Is this a bug? What can we do about it?

Binding a sequence to an external variable?
by Johannes Krampf 18 Dec '12

18 Dec '12

Hello, I would like to bind a sequence of xs:string to an external variable. I've tried various ways and after trying to read the source and the spec I fear that it might not be possible. First of all the code: Inside the xquery: declare variable $mysequence as xs:string* external; On the Java side: ClientQuery clientQuery = clientSession.query(query); clientQuery.bind(parameter, values.get(parameter)); I tried to give the type "xs:string*" as a third parameter to clientQuery.bind, but I got the error message "org.basex.core.BaseXException: [XPST0003] Unknown type 'xs:string*'", so this is not the way to do it. I furthermore tried to pass a string array as a parameter, but the variable got the value of the output of the toString method. When I tried with a list of Strings, I got again the output of the toString method. What I want is something like the following: let $mysequence := ("Hello", "world") but using sequence values transmitted from the java application using an external variable. Is there any way to achieve this? The goal is to test for membership in the sequence, i.e. allowing the parametrize the query using a variable number of possible values. Thanks for your assistance, Johannes

Full Text Index giving error for ..7.5 GB XML Data
by John Best 18 Dec '12

18 Dec '12

Dear XML Team, I have a XML DB of size 7.5GB. When creating an Full-Text Index I get an error message - * Out of Main Memory. You can try to: - increase Java's heap size with the flag -Xmx<size> - deactivate the text and attribute indexes.* I tried this with 7.3 and thru GUI... To make searching fast I need FT Index.. :( Another interesting thing I would like to highlight about this error.... In the data folder the FT Index files (ftxXX and ftyXX is the format of the files) are created... The first time when this happened, I checked the data folder and found that the above ftxXX and ftyXX files where up to ftx23 and fty23. Then I tried Full-Text index again with no success. Again I checked the same files. This time they were up to ftx36 and fty36... This might help you that is why I am mentioning..... -- Have a nice day JBest

I've tried separating the entries with ; or , or spaces but none of that seems to work. if I do the full command separated by ; (i.e. set bindings $dname=...; set bindings $inputf=....; set bindings $inputn=....) only the last one takes.

Java bindings error

strange behavior of ft:mark() and ft:extract()
by Francis Avila 14 Dec '12

14 Dec '12

ft:mark() and ft:extract() cannot be used with any intermediate looping construct, at least in BaseX 7.3. For example: > create db ftex "<r><a>text example string</a></r>" > xquery ft:mark(db:open('ftex')/descendant::text()[. contains text 'example']) text example string > xquery db:open('ftex')/descendant::text()[. contains text 'example'] ! ft:mark(.) text example string Notice that the use of a loop means that ft:mark() no longer works. This doesn't work with ft:search() either: > create index fulltext Index 'FULLTEXT' created in 7.63 ms. > xquery for $n in ft:search('ftex','example') return ft:mark($n) text example string However this works if there's no intermediate variable binding (implicit copying) even if we do some xpath navigation. > xquery ft:mark(ft:search('ftex','example')/..) <a>text example string</a> Query executed in 0.96 ms. > xquery ft:mark(ft:search('ftex','example')/../..) <r> <a>text example string</a> </r> However (this is a separate bug), the document-node() parent/child ordering is messed up: > xquery ft:mark(ft:search('ftex','example')/../../..) <r> <a>text </a> </r> example string > xquery ft:mark(ft:search('ftex','example')/ancestor::document-node()) <r> <a>text </a> </r> example string It seems to me that probably there is some extra hidden metadata attached to the text node which is not preserved by any implicit copying, such as by loops. (Although I'm not sure what's going on with the document-node() example.) One example of where this is a big headache is when we want to know in which document was a the text match. Here is a natural implementation: QUERY: for $n in ft:search('ftex','example') return <r doc="{document-uri($n/ancestor::document-node())}">{ft:mark($n)}</r> RESULT: <r doc="ftex/ftex.xml">text example string</r> However in this case the text will not be marked. We can't even do this because the "marked" document does not have a reference to the document-node() (which is understandable, as there's probably a copy/modify/return transform under there): QUERY: xquery for $n in ft:mark(ft:search('ftex','example')/..) return <r doc="{document-uri($n/ancestor::document-node())}">{$n/(* | text())}</r> RESULT: <r doc="">text example string</r> The workaround I used is this: QUERY: let $matches := ft:search('ftex','example') for $n at $i in ft:mark(ft:search('ftex','example')/..) return <r doc="{document-uri($matches[$i]/ancestor::document-node())}">{$n/(* | text())}</r> This is extremely ugly, and shares with the last example the downside that I need to mark the *parent* node of the matched text node and then carefully unbox it in the return clause. Quite a "gotcha"! In addition to being ugly, I'm also worried that it may be incorrect because I don't know for sure that the order of search will always be exactly the same (although it *seems* to be). Even if the order is stable, what if the fulltext index is updated by another session between the first call to ft:search() and the second? I don't know what the right answer to all of this is, but the way things are seems very not-good. At the very least the problems with ft:mark() and ft:extract() should be documented with big red text! Perhaps a better method is to have a function with a data structure that contains the text matched text node (as a reference, so that node references are retained) *and* matching substrings explicitly and separately. E.g. a ft:search-with-info('ftex','string example') could return: (map { 'text' := text('test example string'), 'substrings' := (5,8, 14,6) }, ...) or maybe this: (map { 'text' := text('test example string'), 'substrings' := (<s start="5" length="8"/>, <s start="14" length="6"/> ) }, ...) or maybe just a sequence of alternating items: (text('test example string'), <matchinfo><s start="5" length="8"/><s start="14" length="6"/></matchinfo>, ...) Unfortunately I don't see how we can return a simple sequence of elements since the text node result would have to be a copy. With the results separated we could easily make a family of functions which accepts the same data structure and does mark() and extract()-like things with it. The pairs can be processed either with a tumbling window or a for loop with a "where $i mod 2" in it. -- Francis Avila

Perl BaseX API questions
by Liam R E Quin 13 Dec '12

13 Dec '12

(1) The sample perl files and the perl module implementing the API mention a readme file that explains the methods; does anyone know where one might find such a readme file? It might answer my other question... (2) if there's an error in my query and I catch the exception, the message I get is about how many milliseconds the query took, not the actual error. I can enclose my Perl script, but I'm wondering if others have seen this?

Performance Question
by Thomas Kaltofen 13 Dec '12

13 Dec '12

Hi, I have a question regarding performance, because my database shows a somehow strange behavior. I have a database with around 3000 documents, the size of each document does not really matter, because I tried it with small and big documents and there is no real difference (total size of test database is around 40 MB). I am connecting to the database through the client/server interface to execute a query over all documents (all documents have the same structure). The first time the query is executed after the server has been started takes a little longer, subsequent executions of the same query are very fast (around 250 ms). Now I leave the server running for several hours without touching the database at all (e.g. over the night). If I now execute the same query again (the database is still running but was idle for several hours), the execution takes very long (several minutes), but only for the first execution after the idle time, subsequent calls to the query are fast again (around 250 ms). This behavior always happens whenever the database was idle for several hours. What could be the cause for this delay? What I tried already: - Run the database on another computer -> same behavior - Try out different JRE versions (6, 7) -> same behavior - Try out different BaseX versions (7.3, latest 7.5 snapshot) -> same behavior - Start the VM with different options regarding performance & garbage collection -> same behavior - Use smaller or larger documents in the database -> same behavior - Execute a different query -> same behavior I am really running out of ideas and this seems to be independent of the size of the individual documents. What I noticed is that the described lag after the idle phase increases with the amount of documents in the database. Any help and suggestions are appreciated. Thank you! Best regards, Thomas P.S. When (approx.) do you plan to release the next version of BaseX?

Everyone’s feedback is welcome, Christian ---------- Forwarded message ---------- From: Raymond Meester <raymondmeester(a)gmail.com> Hi Christian, A small update on implementing basex. Still working on the issue that BaseXServer suddenly isn't available more (started as BaseXServer -S on a Windows 2008 r2 server). I tried to monitor the process with procmon, unfortunaly due to a leak procmon flooded the page file of the server. So I had to go for another approach. As our administrator are familiar with windows services I tried to install basex as windows service. - First I tried the Java launcher Janel (http://www.redskaper.com/), but I could get it working. Don't know why, but it seemed to be a Janel issue. - Secondly I tried another Java launcher (http://winrun4j.sourceforge.net/). With this launcher I was able to got a working executable. I attached the ini file I used. However to use it as a windows service it needs a java method to work with services (see "Service example" on their webpage). - Last I used the working exe and this manual http://marckean.wordpress.com/2009/05/24/run-shoutcast-as-a-windows-service/ ((I attached the tools which the manual uses: instrv.exe and srvany.exe. (I changed the extension to .txt to get them through the email scanner. I believe they are part of the tool "resource hacker" http://www.angusj.com/resourcehacker/) And now I got BaseX running as a windows service. So of course I would like to see a native way to install Basex as Windows Service, but I thought I let you know how I manage this. Also when there is a better way (not changing the registry directly), please put it on the wiki. Regards, Raymond

I think I have found my problem. I post this here in case it helps anyone else. The java date constructor is initialized with a long, my attempts use a literal are what caused it to fail. I cast my literal as a long xs:long("133554732") and it worked, though not perfectly because epoch is in seconds and java is milliseconds. Thus I had to multiply my literal by 1000 first and then cast it as a long let $fdate: =133554732*1000 let $edat := dt:new(xs:long($fdate)) I then can access the TimeZone.IsDaylightTime property Thanks to Christian for his help on this.

Re: [basex-talk] BaseX in Farsi?

Hi Christian That would be a great idea. I am really interested in. Supporting Persian language makes support of the other right-to-left languages, like Arabic and Hebrew, also possible. As you've said, the first step is to find out how much effort is needed to add the right-to-left format to the editor. I will take a look at it to investigate how to do it and highly appreciate any suggestion.

Hi All, I wrote a xquery in Basex that created an xml file that calculated student grades. Points are dependent on students doing an activity in a window which ends at midnight on sunday each week. The date/time of the activities are stored in the source file in UTC. However, to know if they met the deadline, I need it in local time. I do this by creating a function that translates epoch to a regulate dateTime variable. But I see that when we left daylight savings time, things were thrown off by an hour. The command I use is: adjust-dateTime-to-timezone((xs:dateTime("1970-01-01T00:00:00-00:00") + xs:dayTimeDuration(concat("PT", $v, "S"))),xs:dayTimeDuration('-PT4H')) clearly the problem is the last part -PT4H, because dates that fall after the switch back to standard time from daylight savings time should be -PT5H. Is there a better way of doing this? Is there another command that will give me a localized date that takes into account daylight savings time issues? I tried to set a java calendar but I could not make it work. Any help would be gratefully appreciated. Thanks in advance Randy -- Dr. Randall Reed Assistant Professor, Dept. of Philosophy and Religion Appalachian State University

Dear Ionela, thanks a lot for your support and your feedback. I decided to also pass this on to our BaseX mailing list; hope it’s ok.
