BaseX, Zorba, e-mail module
by Tim Thompson 05 Feb '16

05 Feb '16

Hello, I would like to be able to send e-mail from a Web app I am developing in BaseX and was wondering whether anyone else had implemented this functionality (or whether a BaseX e-mail module might be in the works?). I see that Zorba has an e-mail module with support for SMTP and IMAP (not to mention many other useful modules), which leads me to wonder whether anyone has worked on a BaseX connector for Zorba. In the meantime, I decided to try using the BaseX process module to call Zorba, like so: proc:system( 'zorba', ( '-q', convert:binary-to-string( db:retrieve( 'out', 'email.xq' ) ) ) ) I stored the XQuery code for Zorba as a raw file in the BaseX database, since storing it in the webapp directory caused an error, due to the unrecognized Zorba module declarations. This approach seems to work adequately, but does anyone have any suggestions for improvement, or a different approach? Thanks in advance, Tim -- Tim A.

GUI feature request "Add as import"
by Andy Bunce 03 Jan '16

03 Jan '16

Hi, I often find myself adding module imports in the GUI and I wonder if the following suggestion might speed up that process. Add a new menu item to the filelist right click context menu "Add as import" when the file selection is a XQuery module. The action would be to add a line to the current edit window source with import module namespace {$prefix} = '{$namespace}' at {$path}; Where $prefix and $namespace} are read from the source of the selected file, and $path is calculated from the relative path from the edit file source to the selected filelist source. The line would be inserted at a suitable place in the prologue or at the current location if that is too tricky. /Andy

AUTOOPTIMIZE - was true now false
by James Ball 02 Dec '15

02 Dec '15

Hello, I’m trying out AUTOOPTIMIZE for the first time and I’m not getting what I expect. Running: BaseX 8.3 beta ec9b627 A new database is created with a single document which has TEXTINDEX, ATTRINDEX, UPDINDEX and AUTOOPTIMISE all set to true. This is what INFO DATABASE shows (as I expect): Indexes Up-to-date: true TEXTINDEX: true ATTRINDEX: true FTINDEX: false TEXTINCLUDE: ATTRINCLUDE: FTINCLUDE: LANGUAGE: English STEMMING: false CASESENS: false DIACRITICS: false STOPWORDS: UPDINDEX: true AUTOOPTIMIZE: true MAXCATS: 100 MAXLEN: 96 Now I add a new document (or more than one) to the database. I expect that Up-to-date will still be true and that AUTOOPTIMIZE will still be true. But what I see is both are now false: Indexes Up-to-date: false TEXTINDEX: true ATTRINDEX: true FTINDEX: false TEXTINCLUDE: ATTRINCLUDE: FTINCLUDE: LANGUAGE: English STEMMING: false CASESENS: false DIACRITICS: false STOPWORDS: UPDINDEX: true AUTOOPTIMIZE: false MAXCATS: 100 MAXLEN: 96 Perhaps this is the expected behaviour and I’ve misunderstood AUTOOPTIMIZE? Or is there a bug? Many thanks, James

Running BaseX under Tomcat on a commercial Java hosting provider
by C. M. Sperberg-McQueen 01 Dec '15

01 Dec '15

In case there are other users of XQuery who are looking for a way to get an XQuery engine on the Web but are not sure how to go about it, I have described my adventures setting up one approach (running BaseX 7.9 under Tomcat 6 on a commercial Java hosting provider) in a blog post today, hoping that it might enable someone else to do it with less trouble and confusion than I had: http://cmsmcq.com/mib/?p=1368 When time allows, I expect to upgrade my Tomcat to Tomcat 7 so that I can install a current BaseX; I'll update the post then with information for BaseX 8.*. if those who understand Java development and deployment better than I do (or wish to do) find errors in the exposition or simpler ways to get things set up, I would be glad to have them pointed out. I'd also be interested in speculations as to why setting the default user in web.xml seems not to have worked, but at this point I doubt that it's worth significant effort to solve that problem. -- **************************************************************** * C.

RESTXQ : existing annotation for response headers ?
by Etanchaud Fabrice 30 Nov '15

30 Nov '15

Dear all, When I want to set response headers (for example to force a "save as..."), I currently have to write a specific response before the response body : <rest:response> <http:response> <http:header name="Content-Type" value="text/comma-separated-values; charset=utf-8"/> <http:header name="Content-Disposition" value="attachment; filename={concat($base, '_Parthenay.csv')}"/> </http:response> </rest:response> Is there an annotation to set header values directly in the function declaration ? Best regards, Fabrice

Location of users.xml
by Tom Rauchenwald 27 Nov '15

27 Nov '15

Hi, is it possible to override the expected location of users.xml? >From the wiki (http://docs.basex.org/wiki/User_Management) > The permission file has been moved from the home directory to the > database directory. It was renamed from .basexperm to users.xml We're using the war distribution, and would prefer to either specify the location of users.xml via a parameter or have it reside in the war. Is this currently possible? Thanks, -tom

db:create, namespaces not stripped when input is variable?
by Hondros, Constantine (ELS-AMS) 27 Nov '15

27 Nov '15

Hello all, Any particular reason behind this observed behaviour? (Basex 8.3). .............................................................. [1] .............................................................. declare variable $test := <test xmlns:ce="http://www.elsevier.com/xml/ani/common" xmlns="http://www.elsevier.com/xml/ani/ani"> <ce:initials>M.S.</ce:initials> </test>; db:create('test', $test, 'blah', map {'stripns':true()}) .............................................................. [2] .............................................................. db:open('test')/* .............................................................. [3] .............................................................. <test xmlns="http://www.elsevier.com/xml/ani/ani" xmlns:ce="http://www.elsevier.com/xml/ani/common"> <ce:initials>M.S.</ce:initials> </test> I would have expected the namespaces to be shredded ...

Cant add raw files explicitly or text index ms office docs
by E. Wray Johnson 26 Nov '15

26 Nov '15

Here is what I want to do: For a given folder and all its subfolders on my physical dive, mirror its contents including the contents of archives, parsing xml, json,html, text, etc. using their respective parser skipping invalids, and adding all other files as raw. I want archive files (*.zip, *.doxc) to be added as raw, however I want the text inside archive files like docx (ms-word) to be indexed and any files in the archives files that match a filter to be indexed. Note: It would be nice if there was a single db:add method that allowed me to specify a map of filters to parsers with options, where all files that do not match a filter (or are invalid) will be optionally added as raw.

file:read-binary performance
by Jérôme Chauveau 25 Nov '15

25 Nov '15

Hi, My restxq app is very slow to deliver raw files (css, images, js). For example, the restxq method takes around 600ms to load a png file in my browser when it takes only 2ms in a "direct" or "static" way. --------------------------------------- declare %rest:path("/editions/static/{$project}/{$file=.+}") function max.file:file( $project as xs:string, $file as xs:string ) as item()+ { let $path := file:parent(file:base-dir()) || 'editions/' || $project || '/ui/' || $file return ( web:response-header(map { 'media-type': web:content-type($path) }), file:read-binary($path) ) }; --------------------------------------- Why such a difference? How can I improve it? I am using BaseX 8.3 (war version). Regards, Jérôme -- Jérôme Chauveau - CERTIC-DSI - Campus I Université de Caen Normandie
