Yaml serialization
by Marco Lettere 17 Aug '20

17 Aug '20

Dear BaseX team, just out of curiosity, could you imagine what kind of effort it would be to provide YAML as another serialization method for BaseX in addition to XML, HTML, JSON, CSV? The datamodel seems pretty close to the JSON one so maybe a very similar transformation to XML could be implemented ... Ciao, Marco.

Fuzzy is not applied in full-text search
by Lam Hong Thu 17 Aug '20

17 Aug '20

Hi all, I have a problem searching with "contains text" in content of a document using fuzzy. The results which are found with ft:search can not be found again using "contains text". After making some tests I found out 1. Query: 'Commission abc' contains text 'Commissioning' using fuzzy Result: true Optimized Query: "Commission abc" contains text "Commissioning" using fuzzy using language "English" 2. Query: let $query := 'Commissioning' return 'Commission abc' contains text {$query} using fuzzy Result: false Optimized Query: "Commission abc" contains text "Commissioning" Why the optimized query in the 2. case does not contain "using fuzzy" any more? What could I do so that "using fuzzy" is applied there? I use baseX-GUI of version 9.4.1 Thank you in advanced. Thu

Understanding PUL, seeing modified result
by Ben Pracht 17 Aug '20

17 Aug '20

Hi, I'm a bit more familiar with a SQL database like Oracle than BaseX, though I did cut my teeth on MarkLogic. MarkLogic from what I've read seems to handle updates differently than BaseX. I'm working through examples I found from the website, but wanted to adapt them for my own understanding. I believe every time I have the copy keyword, it's creating a copy of variable and applies one or more modfiications to that copy. Because the original isn't changed, it's called "non-updating". For instance copy $c := <peace/> modify ( insert node element german { 'Friede'} into $c, insert node attribute guid {'asdf'} into $c ) return $c the original node <peace/>, even if it were a variable would not be touched. However, insert node element german { 'Friede'} into <peace/> Takes the <peace/> element, modifies it and returns the modified form. Or at least it does not complain. I ran SET WRITEBACK on and set MIXEDUPDATES before starting these examples. Unfortunately, the insert above just returns an empty set. I *think* it puts it into some PUL list, not unlike a set of transactions to be applied. These modifications seem to be invisible to subsequent queries, even in the same session (unlike a SQL database wherein the same session would see the modifications). How can I get these changes flushed so I can see and use the modified result? Separately, if I do haver an insert or some other modification, what's the syntax if I wanted to add a for, let order by or other FLOWR keyword? Kind Regards, Ben Pracht 919.809.2439 ben.pracht(a)gmail.com

Basex huge performance hit in linux (Basex query execution is too slow in linux)
by Nikhil Sethi 17 Aug '20

17 Aug '20

Hi Basex Team, We are facing a huge performance hit in linux machine while using basex, its working smoothly in windows machine While executing any query : -> windows machine takes around 4 to 15 millisec -> On linux machine same query takes around 120 to 150 millisec During some application operation execution we are selecting/inserting the xml nodes in different docs in basex and there are around 13000 xml nodes which needs to be selected/imported in this operation. Linux => rhel or cents of Based on the logs of query execution we have analysed and found : Windows worst case(15 ms) query execution time => 13000 x 15ms => 65000ms => 65 sec = around 1 min Linux average case(130 ms(120+150)/2) query execution time => 13000 x 130ms => 1690000ms => 1690 sec = around 28 min to execute same operation we are using BaseX941.zip ZIP Package eg queries : for $alias in collection(mydbname)//* where (($alias/@id="4249f0807da81000a734525400c54430018") and ($alias/@deleted="false") and ($alias/object-type/@uid="com.MyObjectName")) return $alias or insert node <myxmlNode>…….</myxmlNode> into (for $alias in doc('MyDoc') return $alias) I am using basex with java code to get the result System.setProperty("user.home", db_dir); BaseXXQDataSource ds = new BaseXXQDataSource(); ds.setProperty("serverName", "localhost"); ds.setProperty("port", "1984"); ds.setProperty("databaseName", "mydbname"); XQConnection2 connection = (XQConnection2) ds.getConnection("admin", "myDbPassword"); XQStaticContext xqsc = connection.getStaticContext(); xqsc.setScrollability(XQConstants.SCROLLTYPE_SCROLLABLE); connection.setStaticContext(xqsc); XQPreparedExpression expr = connection.prepareExpression(query); XQResultSequence result = expr.executeQuery(); XQSequence scrollableCopy = connection.createSequence(result); getting result from the xqsequnce for 13000 queries is taking another 10 mins Node node = scrollableCopy.getNode() we have tried to increase xms and xmx in basexserver but it didn't help, Can you please suggest any solution/configuration required for linux machine to increase the performance. Thanks, Nikhil

RESTXQ path resolution
by Ben Pracht 31 Jul '20

31 Jul '20

Hi, I'm trying to resolve a 404 with a RESTXQ service, and got to wondering if it's possible to show the directories it's looking for things, ideally fully qualified paths. Is it possible to turn on logging so much that it shows all the XQ files it found, then show the ones it actually matched? In my case, I put the hello-world service in the main project directory, in the modules directory where the RESTXQPATH and in the RESTPATH. I've tried renaming the hello-world to .xq, .xqm and .xqy. In all cases, it does not find the .xq file. Best Regards, Ben Pracht 919.809.2439 ben.pracht(a)gmail.com

Feature Request: Save untitled, open scripts when exiting GUI
by Andreas Mixich 30 Jul '20

30 Jul '20

SublimeText has this nifty feature, that it saves all open tabs, even if the have no representation on the filesystem, so one can continue exactly, where one has left off. I find myself often to have several, unnamed, XQueries open, to test this concept, to compose that function, etc. It would be nice, if one could simply shut off and have them reopened next time without naming a file and saving each item in question. -- Minden jót, all the best, Alles Gute, Andreas Mixich

BaseX 9.4 - XQuery locks - documentation query
by James Ball 30 Jul '20

30 Jul '20

Hello, I was just looking at the changes to locking for 9.4 and I think the documentation has got ‘garbled’ in an update. https://docs.basex.org/wiki/Transaction_Management#XQuery_Locks <https://docs.basex.org/wiki/Transaction_Management#XQuery_Locks> " The lock may be transformed to a write lock by cominthe operations as Similar to the internal database locks, write locks block all other operations while read locks allow parallel access. “ I think this line should be two bullets but I’m not sure what ‘cominthe operations’ should be? Combining? The lock may be transformed to a write lock by combining operations Similar to the internal database locks, write locks block all other operations while read locks allow parallel access. I’m happy to update the wiki but I wasn't confident enough that I’ve understood the 9.4 change to do it without first checking on the list. Regards, James

I am evaluating BaseX for my XML project. I need transaction support like - Start transaction - Run queries (read, write, update) - Commit or rollback transaction When I see the documentation, it lists Transaction Manager. But when I look at the details, I cannot find anything like that. Anyone can explain me how is the support, or is there an add-on or planned something? Best regards Reto, Frauenfeld, Schweiz

Possible bug in database size (bytes) after database optimize from BaseX Database Administration
by Geoff Alexander 16 Jul '20

16 Jul '20

I've found that when I perform a database optimize on an unoptimized database that while the record count decreases as expected, the database size (bytes column) stay the same. Is this a bug in reporting the database size (less severe problem) or a bug in the database not reducing on optimize (more severe problem)? I've encountered this with both BaseX 8.6.7 and 9.3.3 running on Windows 10. Thanks, Geoff Alexander, Ph.D. Software Engineer, Corporate Tools Development IBM Corporation Charlotte, NC

Database file path
by Vladimir Churyukin 16 Jul '20

16 Jul '20

Hello, We have a data transformation pipeline that works with XML files of different sizes, sometimes big (up to several gigabytes). We are using BaseX to do the transformations. For smaller files we use the MAINMEM option, because the whole database can fit in memory. But for some files we can't do that, but all databases we create are simply disposable, and we'd like to control where we put them, and destroy them after the processing. Is there a special option or any other way to specify where particular database's files will reside? How to specify that when we call CreateDB command? thank you, Vladimir

Corrupt database after update
by Johannes Bauer 16 Jul '20

16 Jul '20

Hi, we have a rather strange and hard to track problem with corrupted databases. Our setup is: * Docker container with a Tomcat that hosts BaseX with some custom RESTXQ services * BaseX 9.2.4 * Java 14 * Docker runs on a Linux VM Workflow * Create database with RESTXQ service call * Import JSON document with RESTXQ service call o call this multiple times. After some Import calls, the import fails and the database is corrupt from this point on. We first thought that it has something to do with the content of the document. But we found no pattern. Sometimes it works, but sometime it does not. There is no concurrency involved. There are no other clients that read or write to the database. We also tried to deactivate the UPDINDEX setting. But it had no effect and we could reproduce the error with and without the automatic index update. The logs in case of errors look like this: 06:58:00.683 172.18.0.2:33728 admin REQUEST [PUT] /c42-core/api/v1/restxq/user/documents/c42-index/metadata%40document06:58:00.700 172.18.0.2:33728 admin 500 Unexpected error: Improper use?

Joining large files
by Giuseppe G. A. Celano 13 Jul '20

13 Jul '20

Hi, I am trying to perform a join operation between two large XML files (~490 MB and ~40 MB), which are the result of the automatic conversion of old sql dumps into XML files. I created two databases for the files. The query I wrote to join them is correct because it works when I limit the join to just a few items, but it never ends if I apply it to all items: here is the xquery: https://git.informatik.uni-leipzig.de/celano/perseus_morpheus/-/blob/master… <https://git.informatik.uni-leipzig.de/celano/perseus_morpheus/-/blob/master…> here is the first file: https://git.informatik.uni-leipzig.de/celano/perseus_morpheus/-/blob/master… <https://git.informatik.uni-leipzig.de/celano/perseus_morpheus/-/blob/master…> here is the second file: https://git.informatik.uni-leipzig.de/celano/perseus_morpheus/-/blob/master… <https://git.informatik.uni-leipzig.de/celano/perseus_morpheus/-/blob/master…> I have also tried to use the database module functions, but without success. Am I missing anything here? Thanks. Ciao, Giuseppe

Change static directory for html pages
by Ben Pracht 13 Jul '20

13 Jul '20

Hi, I'd like to serve static content in the same server as the one handling the restxq. However, I noticed it expects the content to be in some level under the static directory. Then, the URL also needs the static directory. Is it possible to change both the directory the static files live and the URL? That way I can create a site without requiring the end user to append static to the URL to get to index.html. Ultimately, I want to create static pages, restxq services, schemas and a database, but have them isolated from the BaseX distribution. I've seen some flags to specify some directory locations, but not the static one. I'm using Ant so I can take the source distribution, copy that to a target directory, and in another step, copy my source files. I realize Ant is old, but I have no idea how to do this in Maven. By the way, I absolutely love how easy it is to do a site yet it actually seems quite powerful. Kind Regards, Ben

Celano" <celano(a)informatik.uni-leipzig.de> Hi Giuseppe, The optimizer chooses a suboptimal optimization strategy for your query: The first predicate is rewritten for index access, and the second one is sequentially processed. The search key '3' is static, so it’s possible for the compiler to estimate the evaluation time. The search key for the second key isn’t, that’s why the first predicate is given preference. I used two pragmas to speed up your query: • With db:enforceindex, the optimizer is instructed to rewrite the second predicate for index access. • With db:copynode, memory usage is reduced, and 500 MB should suffice to evaluate the query (even with the GUI, which caches the results in main memory) See [1] for more details. Your query is an interesting one; I’ll have more thoughts on how to improve the heuristics of our query optimizer. Hope this helps, Christian [1] https://docs.basex.org/wiki/XQuery_Extensions#Database_Pragmas declare variable $t:= db:open('hib_parses'); declare variable $u := db:open('hib_lemmas'); for $j in $t//row for $nn in $u//row [field[@name = 'lemma_lang_id']/text() = '3'] [(# db:enforceindex #) { field[@name = 'lemma_id']/text() = $j/field[@name='lemma_id']/text() }] return (# db:copynode false #) { element wf { <f>{ $j/* }</f>, <l>{ $nn/* }</l> } } On 7/11/20, Giuseppe G.

xslt:transform function not working with XML Catalog
by Lizzi, Vincent 10 Jul '20

10 Jul '20

I've encountered a problem using xslt:transform in to transform some old XML that contains a DTD DOCTYPE system literal pointing to a non-working URI and also uses ENTITYREF attributes to refer to image files. I have the XML Catalog configured correctly using CATFILE. The XSLT is using unparsed-entity-uri() to convert the ENTITYREF into a file name for an href attribute. I've tested the XSLT and the XML Catalog in oXygen and in XSpec, so I know they work. I've tried a few alternatives to get this to work in BaseX and have not arrived at a working solution. The BaseX setup uses BaseX 9.3.3, XML Resolver 1.2, and Saxon HE 9.9.1-7. Passing the XML directly to xslt:transform does not use the XML Catalog for parsing the XM. I've tried making the first parameter of xslt:transform a path to a XML file, an xs:anyURI pointing to the XML file, or string containing the XML. Each time the XML fails to parse due to the non-working URI in the system literal. When I change the system literal to a URI that works the transformation works and the unparsed-entity-uri() function produces the expected file name for the href attribute. I also tried parsing the XML using doc() or fetch:xml() first and then using the parsed XML as the first parameter of xslt:transform(). The doc() or fetch:xml does use the XML Catalog to parse the XML. However, unparsed-entity-uri() function produces an empty string because the DTD information is no longer available. Hoping to be able to spot the problem I looked through the BaseX code. XsltTransform is using CatalogWrapper to set a URIResolver, but is not setting an EntityResolver. SAXWrapper is using CatalogWrapper to set an EntityResolver before parsing XML. It looks like this should work, but it's not. The next alternative is to pre-process the XML using a regular expression to replace the non-working URI in the DOCTYPE system literal with a working URI prior to xslt:transform(). This works, but it seems like this is just working around a problem. Has anyone else encountered this problem and found a better solution?

Hello, I ran the following query using BaseX 9.3.3 command-line client: 'hello' instance of xs:anyAtomicType the result of the query is `true`. But if I run this query: 'hello' instance of xs:anySimpleType an error "[XPST0051] Unknown type: xs:anySimpleType" is returned Similarly, for the query: 'hello' instance of xs:anyType an error "[XPST0051] Unknown type: xs:anyType" is returned Should xs:anySimpleType and xs:anyType be recognized? Thank you, Yasir
