Disk full caused by huge index
by Ludovic Kuty 23 Dec '14

23 Dec '14

Dear users, Can I remove the file txtl.basex and still get an access to my data ? BaseX of course will be stopped. My HDD is full and I can't optimize all because BaseX times out. Then I would like to deactivate the UPDINDEX option on my already existing DB. I already read the thread https://mailman.uni-konstanz.de/pipermail/basex-talk/2014-July/006942.html ( UPDINDEX and ever growing index size ) and was well aware of the problem but I didn't know that it would grow so fast. total 214335012 -rw-r--r-- 1 root root 1620720 Dec 23 02:54 atv.basex -rw-r--r-- 1 root root 2300192644 Dec 23 02:54 atvl.basex -rw-r--r-- 1 root root 337605 Dec 23 02:54 atvr.basex -rw-r--r-- 1 root root 15 Dec 23 02:54 idp.basex -rw-r--r-- 1 root root 137256 Dec 23 02:54 inf.basex -rw-r--r-- 1 root root 631959552 Dec 23 02:54 tbl.basex -rw-r--r-- 1 root root 1220641 Dec 23 02:54 tbli.basex -rw-r--r-- 1 root root 146626967 Dec 23 02:54 txt.basex -rw-r--r-- 1 root root 216396026742 Dec 23 02:54 txtl.basex -rw-r--r-- 1 root root 838900 Dec 23 02:54 txtr.basex TIA, Ludovic Kuty

file names with [] and base-uri
by Andy Bunce 22 Dec '14

22 Dec '14

Hi, If I create a database with a file with [] in the name e.g. *bracket[in]name.xml *then /*/base-uri(.) gives the error [XQST0046] URI 'bracket[in]name/bracket[in]name.xml' is invalid. Query: /*/base-uri(.) Is this correct behavior? /Andy

Bug in array:fold-left?
by Marc van Grootel 21 Dec '14

21 Dec '14

Hi, I think I've spotted a bug in array:fold-left (using 20141219 snapshot) array:tail([1,2,3]) => [2,3] array:fold-left( array:tail([1,2,3]), (), function($result, $fn) { ($result, $fn) } ) => (1,2) Using array:fold-right in the above example returns (2,3). -- --Marc

by Marc van Grootel 20 Dec '14

20 Dec '14

Just in: Michael Kay gave fn:apply it's blessing and it will be in XQuery 3.1. Great news. Thanks to the WG and all who participated. I don't want to sound too pushy, but ... eh ... when can we have it ;-)) See: https://www.w3.org/Bugs/Public/show_bug.cgi?id=26585 --Marc

tiny issue
by Rob Stapper 19 Dec '14

19 Dec '14

Hi, Concerning latest snapshot: color scheme doesn't apply correctly on datatype-declarations of function parameters ( as xs:string). It still works fine on the datatype-declaration of the function itself. See attachment Rob --- Dit e-mailbericht is gecontroleerd op virussen met Avast antivirussoftware. http://www.avast.com

What is the best way to implement an async REST method?
by Marc van Grootel 16 Dec '14

16 Dec '14

How would you implement an async REST pattern? I don't remember having seen anything that makes me do this using plain XQuery. Does this mean the only way to tackle this would be via Java and events maybe? I would post to a URL, this URL would accept the post and return a temporary URL where I can check the status of my request, then once it's ready this temp URL will redirect me to the location of the real resource. That's the gist of the async REST pattern that I would like to implement. What would be the best approach to experiment with this? --Marc

BaseX 8.0: DBA
by Christian Grün 15 Dec '14

15 Dec '14

Hi all, This is yet another update on the next, upcoming version of BaseX: We have added a new database administration (DBA) web frontend to our ZIP and EXE distributions. It allows you to create and administrate databases, evaluate queries in realtime, view log files, manage users, and more. It was completely written with XQuery and RESTXQ, apart from a few lines of Javascript code. The new frontend was added due to the known shortcomings of the Java GUI, which cannot be used to run queries on other servers. As a consequence, we have removed the server dialog from the desktop application. We hope that DBA will help you to write your own web applications based on RESTXQ! Some more infos and design goals can be found in our Wiki [1]. Have fun, we are looking forward to your feedback, Christian PS: NO, the web frontend does not provide all the cute features of the desktop gui, like the treemap, scatterplot, syntax highlighting, etc… But it may provide some of them in future. Your contributions are welcome! [1] http://docs.basex.org/wiki/DBA
