[basex-talk] xquery:eval bug?

[Marc van Grootel]

Hi,

I'm trying to return a map or an array from xquery:eval. Seems this is
not possible, yet the signature says it returns item()*

xquery:eval('1 + 1') => 2
xquery:eval('[1,2]') => ERROR: [FOTY0014] Items of type array(*)
have no string representation.
xquery:eval('map { "x": 10 }') => ERROR: [FOTY0014] Items of type
map(*) have no string representation.

BTW: I saw that xquery:eval#3 is documented as returning item() while
the other arities return item()*

Tested on 8.3, haven't tested yet on 8.4beta but it's trivial to repro I figure.

[basex-talk] Security

[Finney, Tim]

Hi Everyone,

Sorry if this is a dumb question. What is a good way to do security in BaseX? I 
found a stub here:

http://docs.basex.org/wiki/Security:_Use_Cases

What I would like is to be able to restrict who can do what with a database. 
Here are a few things I'd like to be able to do:


1.  Grant create, read, update, and delete permissions on  each document in 
a database, and have a default mask for a database document.

2.  Say whether a user can or cannot execute a function or visit a URL (and 
get something besides a 404).

3.  Allow the creation of roles which can be assigned to users. (Having a 
particular role allows all users with that role to do particular things, like 
update docs, or visit particular URLs.)

4.  No doubt there are more desiderata. E.g. one might conceivably want to 
be able to grant permissions at the node level within a document.

Any pointers?

Best,

Tim Finney

[basex-talk] ft:search and using thesaurus

[Günter Dunz-Wolff]

Hi all, hi Christian,

for a flexible search I want to use this programatic approach:

let $ft := map { 'wildcards': true() }
let $terms := 'Pa.*'
for $city in ft:search('factbook', $terms, $ft)/parent::name[ancestor::city]
let $hits := ft:mark($city[ft:contains(text(), $terms, $ft)])
return
let $name := $city/ancestor::country/name
return ($hits, $name)

How could I integrate 'using thesaurus at "thesaurus.xml"', unfortunately 
thesaurus is not part of the $options argument of ft:search.

Cheers, Günter
