BaseX 9.0 (still to come): Improved text compression
by Christian Grün 01 Feb '18

01 Feb '18

Hi all, with version 9.0 of BaseX, texts will be better compressed than before. Short strings and whitespace text nodes will be inlined in our main storage, instead of being stored in an extra heap file as before. This will particularly be helpful when perfoming mass updates on short strings (replace 'yes' to 'no', etc.), and your future BaseX database will get even smaller [1]. Obviously, BaseX 9.0 databases cannot opened anymore with older versions. However, BaseX will be 100% backward compatible, so there will be no need to export and recreate your existing database instances. Instead, all future updates you perform will use the new compression feature; and if you run a complete optimize, all existing texts will be reduced as well. All the best, Christian [1] https://github.com/BaseXdb/basex/issues/1536

Hi all! is there a way to preserve the beginning and ending spaces in the Database xml elements? In other words If I execute this xQuery db:replace("MyDB", "doc.xml", "<a> stefy </a>") the resulted document will be <a>stefy</a> As you can see I lost my beginner and ending spaces. thanks Stefania

Stateless server without sessions
by Christoph Gaukel 01 Feb '18

Hi Team, i designed a service that uses web tokens to identify the users and i try to run this service really stateless, that says without creating any sessions. The service runs as basexhttp and uses Jetty. Is there a parameter, that prevents it from creating sessions at all? Currently curl writes: < HTTP/1.1 406 Not Acceptable < *Set-Cookie: JSESSIONID=1tgnabd2l6y3p1jpg8qv3hb53d;Path=/* < Expires: Thu, 01 Jan 1970 00:00:00 GMT < Content-Type: text/plain;charset=UTF-8 < Content-Length: 19 < Server: Jetty(8.1.18.v20150929) and the service adds a new session per call: sessions: "1gnn17n91gsmuc9grvk417ne 1xim2bo4bmtvr11e4a8tap8cl8 kiy3rq9j5lyq1hf6gf8vy4td2 s5luvfkvdpjv19ikpzqeev9k2 mn50c33fxflz17jv24oc68baw 1tgnabd2l6y3p1jpg8qv3hb53d" Best regards, Christoph
