XQuery changes from 7.6 to 7.7
by Gerald de Jong 18 Aug '13

18 Aug '13

I am finding strange problems when I try using 7.7 which didn't appear before. I was building queries with XQUERY followed by \n and then the query, which worked in 7.6. XQUERY <Documents> { for $doc in collection('oscrtest/documents/Photograph')/Document order by $doc/Header/TimeStamp descending return $doc } </Documents> Now it warns me about the syntax of my query: "Syntax: XQUERY [query]" So then I take away the \n so that the query begins after "XQUERY " and my query becomes: XQUERY <Documents> { for $doc in collection('oscrtest/documents/Photograph')/Document order by $doc/Header/TimeStamp descending return $doc } </Documents> upon which it reports: "[XPST0003] Expecting closing tag </Documents>." Puzzling about why this happens, I adjust the query to: XQUERY <Documents>{ for $doc in collection('oscrtest/documents/Photograph')/Document order by $doc/Header/TimeStamp descending return $doc }</Documents> but then it reports: "[XPST0003] Expecting expression." I will have to stick to 7.6 until I understand what to do about these problems.

Losing non-breakable spaces ( )
by France Baril 17 Aug '13

17 Aug '13

Hi, We are using a BaseX HTTP server (still on version 7.6), accessing files via WebDAV for authoring in XML Oxygen. At some point in the process, we lose our non-breakable spaces. If Isave a file with this content in BaseX: <p>Test this</p> It appears that files are saved correctly, because this query returns the p element: for $x in //text()[contains(., ' ')] return $x/parent::*. However, when we reopen the file in BaseX, the   has been replaced by a space. We tried the same experiment saving and opening the file on the file system to make sure the issue wasn't with XML Oxygen. The file reopens with the correct   character. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

xquery hangs in 7.7 release version (used to work fine in 7.7 beta)
by Srinivasan Muthu 17 Aug '13

17 Aug '13

Hi, We have been using basex 7.7 snapshot from June 20 and wanted to upgrade to the release version but looks like I have hit a bug with BaseX 7.7 release version while running a set of xqueries in sequence. I am able to reproduce this in BaseX 7.7 running in client-server mode on two different machines. Here are the steps to reproduce: - Launch BaseX 7.7 server (with defaults) - Launch BaseX command line client (run the file under bin/basexclient.bat that comes in zip) and run the following commands (also attached a screenshot): ---------------------------------------------------------- Username: admin Password: BaseX 7.7 [Client] Try help to get more information. *> create db d1 <hello/>* Database 'd1' created in 103.22 ms. *> xquery delete node doc('d1')//oops* Query executed in 25.03 ms. *> xquery let $doc := 'd1' return doc($doc)* ---------------------------------------------------------- At this point BaseX 7.7 server cannot be stopped using the stop batch file and I have to kill all processes using Task Manager. These set of commands works fine on BaseX 7.7 snapshot from June 20th. Let me know if this is a bug or am I missing something here. Thanks, Srini

BaseX77 db:optimize exception
by Freihalter Thomas 17 Aug '13

17 Aug '13

Hi all, After migration to BaseX77, db:optimize is running into an exception: java.io.IOException: Stopped at ., 8/20: [java] [FOUP0002] Database 'xxx' is currently opened by another process. Before migration, I used BaseX761-20130303.204518, and this version worked well. I have an additional question: My task is to read objects from a file and replace (if already exists) or insert (if new) the objects in the database. The key is a specific attribute (@n). Parallel threads could exist. Could you suggest a better solution? Here is the log with the exception: 21:32:37.860 127.0.0.1:48933 admin OK Database 'stock_stock_work__DOM' was opened in 74.98 ms. 78.19 ms 21:32:37.865 127.0.0.1:48933 admin REQUEST SET BINDINGS 'b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13':db=stock_stock_work__DOM,'b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13':destination=/tmp/basex/82e63b48-978d-4498-97bc-e90c8a3cd357/stock_stock_work__DOM,'b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13':uuid=82e63b48-978d-4498-97bc-e90c8a3cd357 21:32:37.866 127.0.0.1:48933 admin OK BINDINGS: 'b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13':db=stock_stock_work__DOM,'b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13':destination=/tmp/basex/82e63b48-978d-4498-97bc-e90c8a3cd357/stock_stock_work__DOM,'b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13':uuid=82e63b48-978d-4498-97bc-e90c8a3cd357 6.11 ms 21:32:37.869 127.0.0.1:48933 admin REQUEST SET AUTOFLUSH FALSE 21:32:37.869 127.0.0.1:48933 admin OK AUTOFLUSH: OFF 1.36 ms 21:32:37.915 127.0.0.1:48933 admin OK QUERY[0] xquery version '3.0'; declare namespace uuid='b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13'; declare variable $uuid:db as xs:string external; declare variable $uuid:destination as xs:string external; let $step := ( 1 ) return db:add($uuid:db, $uuid:destination) 44.64 ms 21:32:38.208 127.0.0.1:48933 admin OK RESULTS[0] 291.49 ms 21:32:38.208 127.0.0.1:48933 admin OK INFO[0] 0.19 ms 21:32:38.249 127.0.0.1:48933 admin OK QUERY[1] xquery version '3.0'; declare namespace uuid='b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13'; declare variable $uuid:db as xs:string external; declare variable $uuid:uuid as xs:string external; let $step := ( 1 ) let $prefix := concat($uuid:uuid, '/') let $suffix := concat('.', $uuid:uuid, '.xml') let $new := distinct-values( for $i in db:list($uuid:db) let $n := data(db:open($uuid:db,$i)/*/@n) where ends-with($i,$suffix) return $n ) for $i in db:list($uuid:db) let $old := concat($prefix, $i) where (index-of($new, data(db:open($uuid:db, $i)/*/@n))) and not(ends-with($i,$suffix)) return db:rename($uuid:db, $i, $old) 42.09 ms 21:32:38.359 127.0.0.1:48933 admin OK RESULTS[1] 108.12 ms 21:32:38.360 127.0.0.1:48933 admin OK INFO[1] 0.2 ms 21:32:38.400 127.0.0.1:48933 admin OK QUERY[2] xquery version '3.0'; declare namespace uuid='b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13'; declare variable $uuid:db as xs:string external; declare variable $uuid:uuid as xs:string external; let $prefix := concat($uuid:uuid, '/') return db:delete($uuid:db,$prefix) 40.65 ms 21:32:38.444 127.0.0.1:48933 admin OK RESULTS[2] 43.14 ms 21:32:38.484 127.0.0.1:48933 admin OK INFO[2] 39.64 ms 21:32:38.525 127.0.0.1:48933 admin OK QUERY[3] xquery version '3.0'; declare namespace uuid='b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13'; declare variable $uuid:db as xs:string external; declare variable $uuid:uuid as xs:string external; let $suffix := concat('.', $uuid:uuid, '.xml') for $i in db:list($uuid:db) let $new := substring-before($i,$suffix) where ends-with($i,$suffix) return db:rename($uuid:db, $i, $new) 41.45 ms 21:32:38.576 127.0.0.1:48933 admin OK RESULTS[3] 49.48 ms 21:32:38.616 127.0.0.1:48933 admin OK INFO[3] 39.85 ms 21:32:38.657 127.0.0.1:48933 admin OK QUERY[4] xquery version '3.0'; declare namespace uuid='b1b987d9-3cdb-4ac4-bc83-13bd03eb7a13'; declare option db:queryinfo 'true'; declare variable $uuid:db as xs:string external; declare variable $uuid:uuid as xs:string external; let $step := ( 1 ) return db:optimize($uuid:db, true()) 41.18 ms 21:32:38.727 127.0.0.1:48933 admin REQUEST RESULTS[4] 21:32:38.727 127.0.0.1:48933 admin ERROR Stopped at ., 8/20: [FOUP0002] Database 'stock_stock_work__DOM' is currently opened by another process. 69.73 ms 21:32:38.731 127.0.0.1:48933 admin REQUEST EXIT 21:32:38.739 127.0.0.1:48933 admin OK 8.69 ms And yet another question: Is it possible to store the backup-files (CREATE BACKUP) in another location than the database-directory (e.g. backup-directory)?

Inserts into root nodes within if statements
by Marcel Hanser 15 Aug '13

15 Aug '13

Hi there, i'm confused about following behavior. Consider the query: "insert node <c/> into /" it evaluates perfectly if a DB is opened within the BaseX Gui (7.7). But if i put it into an if statement like: "if(true())then insert node <c/> into / else()" i got the error message that the if statement is not complete. Adding a dot behind the slash solves the problem. "if(true())then insert node <c/> into /. else()" Is there a specific reason behind that? Regards and thanks in advanced, Marcel

BaseX freezes, no error message on webpage or terminal
by France Baril 14 Aug '13

14 Aug '13

Hi, Setup: http server 7.6. Path to .dtd is in the form http:.../rest/path/mydtd.dtd. Test #1. I call the function that contains dtd:validate from a function. It works. Test #2. I call the function that contains dtd:validate from another function. It freezes. The only different I see is that the 2nd function is an updating function, so I am thinking deadlock. However, the function doesn't update the same DB that holds the file to validate or the .dtd file. How do I find out if this is a dead lock situation? And what would be my options to get out of it since I am not updating the same DB from which I read the content file or the .dtd file? Is there anyway to collect more information from the server to confirm the deadlock theory? The catch is not returning anything about being locked out either. The process doesn't seem to get pass the validate:dtd line in the try... it never makes it into the catch. Thanks, France -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com (514) 572-0341

Efficiencies for batching
by Wendell Piez 13 Aug '13

13 Aug '13

Hi, Currently when I need to batch a database for processing I do something like this: for $record at $p in $recordSet where ($p ge $start) and ($p ge $end) return $record/process-record(.) I can imagine why this is more efficient. in BaseX, than using an XPath filter expression, as in $recordSet[position() ge $start and position() le $end]/process-record(.) (which is what I might prefer to do in other environments). But is the 'where' clause the best I can do? XQuery 3.0 has tumbling windows. I am not iterating over subsequences, but rather selecting one (arbitrary) subsequence from a sequence. What's my best approach to this in BaseX? Thanks, Wendell For example, XQuery 3.0 has tumbling windows.
