UPDINDEX
by pw＠themail.co.uk 02 Jan '13

02 Jan '13

Hello List I am working with 7.5 and am looking for guidance on setting UPDINDEX If I run the basex http server from the command line and GET UPDINDEX it is initially false. If I then open the client and GET UPDINDEX it is also false (as expected). Through the client I can then set it with the command "set updindex true". This time GET UPDINDEX returns true through the client but false through the httpserver. How do I set the updindex option so that it it operational for the REST service? Thanks Peter

Re: [basex-talk] how to pass raw bytes intact?
by jidanni＠jidanni.org 02 Jan '13

02 Jan '13

Our mission today is to use Basex to remove tags injected right between the bytes of multibyte UTF-8 characters. http://www.couchsurfing.org/group_read.html?gid=430&post=13986932 >>>>> "CG" == Christian Grün <christian.gruen(a)gmail.com> writes: CG> Have you tried method=raw, as mentioned in our documentation CG> (http://docs.basex.org/wiki/Serialization)? Sorry. Try it yourself: echo '<A>你好</A>'|perl -pwle 's![^[:ascii:]]!$&<wbr/>!'|basex -q ' declare option db:parser "html"; declare option output:method "raw"; doc("/dev/stdin")//*:wbr/..' There is no way to cleanly restore the shattered UTF-8. I would also like to try declare option output:encoding "RAW"; or "BYTES" or "NONE" but on http://docs.basex.org/wiki/Serialization it just says "all encodings supported by Java" So one is supposed to look at http://www.google.com/search?q=all+encodings+supported+by+Java etc. etc. Why doesn't basex have a command that would output the current "all encodings supported by Java" that it is using.

Initial xquery for full text and geospatial search of ISO 19115 docs
by David Stuebe 31 Dec '12

31 Dec '12

Hi Basex Folks I have written a simple minded xquery script which can be used in a post to search ISO 19115 metadata documents. As I am a newbie to xquery and basex I expect that is much that I could do to improve performance, but currently searches take up to 15 seconds. The server hardware is not blazing fast and we are running inside tomcat… but that is certainly not acceptable for a database which is still quiet small. Initially it was fine, responding in less than a second, but when we expanded from less than 100 docs to about 35000 the time grew at least linearly. I am hoping this is due to my poor xquery programming or a setting on the server. Here is the query we are running using a post request with the declared variables at the bottom filled in by the UI: https://github.com/asascience-open/glos_catalog/blob/master/queries/full_se… Here are some of the ISO xml documents that we have in our basex DB: https://github.com/asascience-open/glos_catalog/tree/master/ISOs It is used by this site: http://explorer.glos.us/ To provide geospatial metadata search. Fill in a text value like "water" or "temperature" in the search box in the top right… The server is here: http://64.9.200.113:8080/BaseX73/ User Name: user Password: glos ACL: read only I am hoping it is as simple as a setting on the basex server. Here is the current server info: info database Database Properties Name: glos Size: 422 MB Nodes: 17045388 Documents: 34922 Binaries: 0 Timestamp: 27.12.2012 00:58:03 Resource Properties Timestamp: 22.12.2012 01:43:05 Encoding: UTF-8 Whitespace Chopping: ON Indexes Up-to-date: true Text Index: ON Attribute Index: ON Full-Text Index: ON The index info is available here: https://github.com/asascience-open/glos_catalog/blob/master/queries/glos_in… David Stuebe Scientist & Software Engineer – RPS ASA 55 Village Square Drive South Kingstown, RI 02879-8248 Tel: +1 (401) 789-6224 Email: David.Stuebe(a)rpsgroup.com<mailto:David.Stuebe@rpsgroup.com> www: asascience.com<http://www.asascience.com/> | rpsgroup.com<http://www.rpsgroup.com/> A member of the RPS Group plc

Hi Christian I just downloaded the BaseX 7.5 zip archive and ran the httpserver.bat file ... On the local machine I was able to access using the localhost or machine name as URLs, but access from elsewhere on the network got to the Jetty server (it logged "access denied") but apparently no further. Peter Hi Peter, the combination of BaseX and Jetty is successfully applied in many productive client/server environments. Can you provide us with some more details on how to reproduce the issue? Thanks, Christian ___________________________ > hello list --- Happy Christmas & New Year > > If I run the http server (Basex 7.5) then I can access through Jetty. > When I try to access the same across the network I get nothing > through and "Access denied" in the Basex logs.

hello list --- Happy Christmas & New Year If I run the http server (Basex 7.5) then I can access through Jetty. When I try to access the same across the network I get nothing through and "Access denied" in the Basex logs. What's the solution? Many thanks Peter

Re: [basex-talk] Java Heap Space Error
by Dirk Kirsten 29 Dec '12

29 Dec '12

Dear John, should work as well on the mailing list, so I am answering on the list. Maybe someone else can benefit from your question as well. For an OutOfMemoryException I would always simply try to increase the Java Heap space using the -Xmx option starting BaseX. if this is not helping, maybe some bug was introduced in a newer version. To check this we need a simple self-contained example, i.e. a simple query and some data to demonstrate the problem.

RFE: Turning off parts of the BaseX REST interface
by C. M. Sperberg-McQueen 22 Dec '12

22 Dec '12

I am building some Web-based services for a project I'm involved with, using the BaseX REST interface, and the experience has given me an idea for a possible enhancement to BaseX. It's extremely convenient for development to be able to issue arbitrary queries from the REST interface, but in my role as part-time system administrator and worrier about security, the REST 'query', 'command', and 'get' operations worry me to death. I am happy for the user access control provided by the GRANT command, and I find myself thinking it would be even nicer to have more control. I am happy to discover by experiment that a user with READ access only to a single database sees only that database name when they issue the the default GET request (http://hostname:8984/rest). When I allow my security paranoia full sway, I find I would like to be able to ensure that only authorized users can - perform arbitrary queries using the 'query' or 'command' interfaces - perform particular queries using the 'run' interface Concretely, in this case I would like to be able to create a user for restricted access, which I'll call PUBLIC for now, and ensure that a user who presents the PUBLIC userid and password - cannot fetch any data using the GET interface - cannot run queries using the rest:query interface - cannot run commands using the rest:command interface - can run only specified modules from the HTTPPATH directory (so we can limit the portions of the database we expose to the PUBLIC user -- I think of this as very roughly analogous to being able to limit a SQL user to particular views instead of to the underlying base tables) Of course, by running a packet filter we can ensure that the BaseX server only receives packets from (or: purporting to be from) the project's host, and we can keep the user password for the PUBLIC user secret in what I believe is the usual way (it's there in the source of the PHP module, but web users don't get to see the source of the module). The restrictions I have in mind would serve the purpose of attempting to limit the damage an adversarial user could cause if the user credentials were exposed or (in the case of limiting users to specific modules) if an adversary were able to add modules to the HTTPPATH directory. Disclaimer: I am not a security expert, just (at the moment) a worrier. You will surely be able to get advice from people who understand security issues better than I do. Thank you again for this extremely helpful software. -- **************************************************************** * C. M.
