Backing up database
by Sony Vijay 16 Apr '12

16 Apr '12

Hi, I am trying to maintain a daily backup of all the XML files stored in the database. When I run CREATE BACKUP *, zipped backups of all the databases are created. I unzipped these archives and noticed that the files inside are stored in an internal basex format. Please see an example archive attached. Will I be able to restore these archives to original state if I upgrade to a newer version of BaseX? Will the files in the internal format be compatible with newer versions? If not, is there an alternative way of creating backups? Or, do you suggest I write an XQuery to create timestamped versions of files? Thanks, Sony

time out
by Cerstin Mahlow 16 Apr '12

16 Apr '12

Hi, I have a Web interface (cgi-bin) that allows users to search a collection and store specific results. Although each user has to log in with a personal account, they all use the same interface and thus create a session with: my $session = Session->new("localhost", 1984, "admin", "admin"); It is possible that several users access the collection at the same time and run different queries. From time to time (I cannot see a specific pattern), they report a time-out. It is not because they try to cancel a query by clicking the back-button. If they try the same query a few minutes later, it runs without a time-out. These queries need between 200 and 14000 ms in the GUI and have around 2000 to 4000 results. I wonder whether this time-out is due to overload of the server as such (I have a virtual server only with 2GB RAM and don't know who else is using it for what) because it needs so much time to compute the results, or due to concurrent access to the collection all run with the "admin" user? The result for a query is a HTML code with checkboxes, the rendering of each element is done within XQuery. Perhaps this makes the whole process too slow and the browser times out waiting for the results? Best regards Cerstin -- Dr. phil.

Did REST interface just start enforcing Content-Type?
by Charles Duffy 11 Apr '12

11 Apr '12

Howdy -- The following is arguably a bug in my REST bindings rather than the server, but it worked as of the 7.2 release but fails as of the current 7.2.1 snapshot. A request akin to the following: POST /rest HTTP/1.1 Host: 127.0.0.1:8984 Content-Length: 86 Authorization: Basic cmVhZG9ubHk6cmVhZG9ubHk= Content-Type: application/x-www-form-urlencoded Accept-Encoding: identity, deflate, compress, gzip Accept: */* User-Agent: python-requests/0.10.6 <rest:query xmlns:rest="http://basex.org/rest "><rest:text>1+1</rest:text></rest:query> Yields the following response: HTTP/1.1 400 Bad Request Content-Length: 40 Server: Jetty(6.1.26) Unknown option '<REST:QUERY XMLNS:REST'. ...but did not do so previously.

GUI no longer pretty-printing?
by Charles Duffy 11 Apr '12

11 Apr '12

Howdy -- I'm accustomed to the GUI providing XML output in easy-to-read, pretty-printed form. I just upgraded to 7.2.1-pre-20120410.144517, and that behavior no longer appears to be the case -- documents (as displayed in the GUI) have no whitespace they weren't originally created with. Is this an intentional change? Is a toggle available?

glob syntax
by David Leigh 11 Apr '12

11 Apr '12

I'm trying to use the CREATEFILTER directive to: . Include all files WITHOUT an extension . Exclude all files WITH an extension . Exclude the specific file "_cache" (note, it has NO extension) . Do all this for a whole directory tree I notice that CREATEFILTER uses "glob syntax" (http://docs.basex.org/wiki/Commands#Glob_Syntax) Questions: 1. Since this is a java program, does that mean that: http://docs.oracle.com/javase/tutorial/essential/io/fileOps.html#glob and http://docs.oracle.com/javase/7/docs/api/java/nio/file/FileSystem.html#getPa thMatcher%28java.lang.String%29 provide the exact full description of "glob syntax" for BaseX? 2. If so, can I do what I want to do with some sort of a "!" (negation) pattern? 3. Should this work with version 6.3.5 of BaseX? Thanks! David <mailto:david@leighweb.com> DavidEmailSig

fn:collection
by Róbert Kohányi 09 Apr '12

09 Apr '12

BaseX's documentation and the following (an excerpt from an email on the mailing list[1]) says this on the fn:collection function: fn:collection() either returns documents of a database or of the specified > location >From this it seems that it can return the documents of a specified location (without ever creating a database), however the following query: collection("<xml-dir>") reports the following error (using both the GUI and the command-line): [FODC0004] File or directory "File or directory "<basex>" not found." not > found. (Using Windows 7) I passed several kind of path to the collection function ("c:/xml-dir", "file:///c:/xml-dir", ...), but none of them works. Also, the actual path of "<basex>" in the error depends on whether I start the GUI (<basex>/BaseX.jar) or the command-line (<basex>/bin/basex.bat); the respective paths in these two cases are "<basex>" and "<basex>/bin". (Issuing something like doc("<xml-dir>/<xml-file>") works.) Is this the expected behavior? If yes, is that means that using BaseX one can only query multiple XML files after creating a database for them? If not, ... is this a bug? (I highly doubt.) (On a side note: something like DataDirect - supposedly - can do[2] would be awesome in BaseX. Was this ever considered to include in BaseX?) My reason for doing a query like this is: I've just tried to ran it and it didn't work, so I'm here. Thanks!
