Variable value nulled when passed to an xsl
by France Baril 15 Jan '14

15 Jan '14

Hi, I am using BaseX 7.8 beta 3b557bd. When I pass a variable where the value is provided by a function ( *let **$string-variable* := *freeze-test:get-localized-string*('en-us', 'application')) that extracts the data from the database, I cannot pass it as a parameter to an xslt. It nulls the value. I attached a code sample and a simple database that holds a single file. In the sample, if you replace the line : *let **$string-variable* := *freeze-test:get-localized-string*('en-us', 'application') with *let **$string-variable := *'application', you'll notice that the value is output correctly. The issue is not with getting the value. When using the original variable setting (*let **$string-variable* := *freeze-test:get-localized-string*( 'en-us', 'application')), the debug line (*let* *$debug* := *file:write*( 'debug-string-var.txt', *$string-variable*)) does output the extracted value in the .txt file correctly, which means the variable $string-variable has been set, it just doesn't survive being passed as a parameter to xslt:transform. Note that this used to work in BaseX 7.7.2. The fact that the variable gets nulled is a completely new phenomena.

Experience for management of tons of xml doc using exist-db
by easy 15 Jan '14

15 Jan '14

Hi,all, Based on my discontinuously near ten years experience using exist-db, I made a plan to using exist-db to management more than millions people's EHR, till now, it almost can work, here is what I have done: 1) split the large quantity of doc into small collection( not one collection for one people, but one doc for one people), target to speed query personal info and insert new record nodes. 2) with the kind developer 's help , we can using new range index to quick query big data based on some conditions. 3) using the backup policy to do backup. ... But, there are still some difficult to worry about: 1) exist-db often caused corrupt for a heavy load query, and this often cause db recover fail. and how to avoid heavy load query to affect other query? 2) when will use re-index? after corrupt? the re-index process is very time consumed. how to accelerate re-index? 3) how to control concurrently update db? often this cause the db stop responding to xquery, and as 1). everyday there will more than 1000000 files add to the db, so this is a difficult problem. 4) how to control backup copys ? the backup file will cost large disk space if all old copy exist. Thanks for advice -- 此致 easy 莫愁前路无知己，天下谁人不识君。

Unexpected error. Improper use?
by France Baril 14 Jan '14

14 Jan '14

Hi, I have code that used to work with 7.7.2, but that crashes with 7.8. I was able to create a simple piece of code that reproduces the error. I file:write the result before the db:replace. Notice how some elements have been re-ordered. To run the attached file: * Create an empty DB named 'tui-test' * Access: http://localhost:8984/tui/test-1 Details: Unexpected error: Improper use?

by Ioannis Kavvouras 14 Jan '14

Hello, I am trying to connect to a baseX (remote) server through xmldb-api following the examples in the git-hub but it fails giving Invalid Uri error. I can access the database through REST using the following url: http://<serverip>:8181/BaseX772/rest/wcs-collection/ but I cannot connect using the xmldb url xmldb:basex://<serverip>:1984/wcs-collection or xmldb:basex://<serverip>:1984/ or xmldb:basex://<serverip>:1984/rest or using the 8181 port.

Release Package
by Stefan Sechelmann 14 Jan '14

14 Jan '14

Hello, I’m trying to keep up to date with BaseX and test integrating the BaseX snapshot versions (at the moment 7.8 beta) into our environment. Here is my question: How do I build the structure that can be downloaded from the website containing all files and folders. Running e.g. mvn package yields only the API and core jar files. What am I missing?

adding too many documents is slowing down collection operations
by Fabrice Etanchaud 14 Jan '14

14 Jan '14

Dear all, I'm working on a collection containing tens of millions of documents, updated weekly. My first guess to store these documents was to simply db:add/replace/remove them. This solution is slowing things down as the count of documents increases. For example, opening one collection takes up to 4 minutes. I believe that the document list is an in memory structure. Is there a way to speed things up, or do I have to change sides with the following guess, in order to reduce the 'physical' document list size : 1.group documents in 'logical' documents on insertion (fewer documents containing new or updated documents under a root xml element) 2. remove the old version of these documents in the previous 'logical' documents with xquery update. Has anybody already find that problem, and a workaround ? BaseX is just fantastic ! Best regards, Fabrice Etanchaud Questel/Orbit
