Out of memory bug
by Ivan Lagunov 31 Jul '13

31 Jul '13

Hello, I've got 'Out of memory' error and corrupted database again, this time it's for 6.3 version. Steps: 1. Started server, started terminal client, checked there are no text and attribute indexes. 2. Started my Java application that runs several tests on database: querying, adding, removing. 3. Then I forgot to reopen terminal client and used the one that I opened in Step 1. 4. Run optimize command for the collection and got error. 5. Cannot open the collection any more as I'm getting '… [View More]

invalid collection name?
by C. M. Sperberg-McQueen 27 May '13

27 May '13

Using the GUI interface to BaseX 7.2, when I select Database / Open and Manage ..., I get a list of the databases I have built over the time I've been using BaseX. When I try to open the collection named MEP.bigbooks, though, I get an error box saying "Name 'MEP.bigbooks' is invalid." In the "Manage Databases" dialog box, the information about the collection appears normal and plausible (at least, the size is about what I expect, and so on). It's only when I try to open the collection … [View More]that I run into the error. I get similar errors on other collections which have . in their name; I do not get errors when opening other collections built (as far as I can remember) at the same time from the same data, if their name does not include a full stop. When I try renaming the collection without the full stop, I get the same error message. When I try to issue the command ALTER DATABASE MEP.bigbooks MEPbigbooks from the server command area of the GUI, I get a short syntax summary in the Query Info area complaining about the syntax of the command. When I replace MEP.bigbooks with MEP\.bigbooks and "MEP.bigbooks", I also get syntax errors. If I close the GUI and just rename the directory within my BaseXData directory, the database appears to open normally. I think I have two questions: Q1 is just renaming the directory a safe way (assuming no server is currently working with the data) to rename a collection? Should I do the same for all the other collections I have that don't currently open? I assume that if the 7.2 GUI won't let me rename them, it also will have trouble deleting them, so a related question is: is just deleting a sub-directory of BaseXData a safe way to delete a collection? Q2 Did the rules for names of collections change? Or is there some other cause? Speaking for myself, I guess that as a user I haven't thought much about what characters should be allowed in collection names, but I may have assumed that if they are not unrestricted, they would be restricted to being legal NCNames. I do kind of like using dots in names, so you can count this as one vote for relaxing the naming rules at some convenient moment. It's not a really important point, of course. best, Michael -- **************************************************************** * C. M.

xslt:transform, spaces and mixed content
by France Baril 14 Aug '12

14 Aug '12

Hi, I have an issue with spaces in mixed content, when applying the xslt:transform command. I have been working around it for months with a hack in my css that puts the spaces back as   on inline elements, yet I still haven't run upon a clue to help me resolve this for good the clean way. IN SUMMARY - The xslt applied to my xml outside the BaseX environment (Oxygen + Saxon) gets me right html content (with spaces for inline elements in mixed content) - The query, when it … [View More]

What is the easiest approach to edit data in a browser and have that data stored as xml in basex
by Alex Muir 01 Aug '12

01 Aug '12

Hi, So I've got a client interested to create a dataset of music information such as artist, track name, album release year... and store that in XML. Non technical users would need to view and edit the music info in a web interface and the data would be stored in XML. I was looking at Typo3 which seems to be able to work with basex. I wonder what is the easiest approach to edit data in a browser and have that data stored as xml in basex? What are CMS solutions that work with basex? Is typo3 … [View More]

Deploy BaseX 7.3 as a web application
by jSb_line＠gmx.de 30 Jul '12

30 Jul '12

Hi, we deployed BaseX 7.3 as web application in a tomcat7 cluster environment. The rest service is running fine in local mode, but we ve a security issue... We don't want that someone can modify the xml databases, so it must be readonly, but with no password protection. Is there a way to do this in local mode? Thanks in advance, jan

XSD validation performance
by Seenivasan Gunabalan 27 Jul '12

27 Jul '12

Hi, I have encountered an performance issue while validating xml(5kb) against xsd's(12kb). It took nearly 30 seconds for the validation. As baseX is using java API's, we did the same validation using simple java. we noticed that the caching of schema object reduces the time significantly(from 30 seconds to 8 milli seconds.). Is there a place where we could configure to enable/diable caching of schema or it needs the code to be re-factored or is there a workaround? Thanks, Seenivasan
