Inserting a two double quoted attribute
by Ramzi Hammouda 27 Jul '20

27 Jul '20

Hello BaseX team, I need to insert a node that has an attribute with two double quotes. An example: let $message:='<Amt Ccy=""GBP"">3.00</Amt>' return insert nodes fn:parse-xml-fragment($message) as last into doc('testingdb/testing.xml') The GBP attribute is with two " so it gives the error: SAX: file://C:/Program$20Files(86)/BaseX/(Line1)<file:///C:/Program$20Files(86)/BaseX/(Line1)>: whitespace expected, attribute name found. How can I solve the issue? P Respectons ensemble l'environnement. N'imprimez ce message que si n?cessaire. Let's respect the environment together. Only print this message if necessary.

Transaction Support
by Reto Peter 17 Jul '20

17 Jul '20

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?
