Options for ft:search
by Sebastian Zimmer 15 Mar '21

15 Mar '21

Hi, I'd like to request a feature concerning the ft:search method: An `lserror` option that works exactly like the global option `LSERROR`. It would be nice if we could set the maximum Levenshtein distance specifically for each fuzzy search without having to adjust the global option. Another question on ft:search: Is there a reason why it doesn't have a `case` option just like ft:contains has one? Best regards, Sebastian

Feature Request: Save untitled, open scripts when exiting GUI
by Andreas Mixich 30 Jul '20

30 Jul '20

SublimeText has this nifty feature, that it saves all open tabs, even if the have no representation on the filesystem, so one can continue exactly, where one has left off. I find myself often to have several, unnamed, XQueries open, to test this concept, to compose that function, etc. It would be nice, if one could simply shut off and have them reopened next time without naming a file and saving each item in question. -- Minden jót, all the best, Alles Gute, Andreas Mixich

Update of arbitrarily selected elements?
by Joshua Kordani 03 Jun '19

03 Jun '19

Greetings all. I am curious about how basex supports the idea of modifying any given (or set of given) elements, say a user makes a query to select a bunch of elements for editing and wishes to add an attribute to an arbitrary subset (as in, not selectable with a query), how do I reference a particular element for later updating?

archive:create - Out Of Main Memory
by Han (US), Paul P 29 May '19

29 May '19

Hello, We encountered Out Of Main Memory when trying to create archive of a 4GB XML file. I'm using version BaseX922.war. We allocated 20GB with -Xmx flag for tomcat. Please let me know if there is a way to overcome this issue. let $files := file:list('/tmp', false(), '4gb.xml') let $zip := archive:create($files ! element archive:entry { . }, file:read-binary('/tmp/4gb.xml')) return file:write-binary('4gb.xml.zip', $zip) Thanks, Paul

FW: Attempting to write bulk import of files is failing
by Joshua Kordani 27 May '19

27 May '19

CC group, my mistake. -----Original Message----- From: Joshua Kordani Sent: Wednesday, May 22, 2019 14:12 PM To: Christian Grün <christian.gruen(a)gmail.com> Subject: RE: [basex-talk] Attempting to write bulk import of files is failing Christian, Thank you for your reply. I don't understand why import-all.xq would throw this warning and import-and-process.xq would not. In the case of the latter, the nodes imported with that call are in fact updated properly, while in the former, no updates are seen. Can you tell me why -u would change the behavior of the one and not the other, or in other words, what is different about the two queries that makes this distinction important?

Forgive me if this is hard to read, it was my first attempt at making a function which updates some records and then imports in the same query. Looks fine.

I receive a message about updates not being written back. My first attempt to write that function inside of a for-each also failed. This warning is only shown on command line. It simply indicates that your updates won’t be propagated back to the original files. If that’s what you would like to achieve, you can use the command-line argument -u (see [1]). If something else is not working as expected, feel free to provide us with more details.

Attempting to write bulk import of files is failing
by Joshua Kordani 22 May '19

22 May '19

https://pastebin.com/BEA6XiE5 I write the function in lib.xqm as a standalone query. All it does it add some attributes to each testcase before importing the content into the database. Forgive me if this is hard to read, it was my first attempt at making a function which updates some records and then imports in the same query. I decided to break that query out into its own function, where I then call it from another query, import-and-process.xq, which works as expected. I am now trying to write a bulk import, which is import-all.xq and this is not working. I receive a message about updates not being written back. My first attempt to write that function inside of a for-each also failed. I've read all the documentation I can get my hands on regarding how to write the kinds of queries I need but there still seems to be gotchas I can't seem to see in advance. Any help would be greatly appreciated. Joshua Kordani DISCLAIMER: This email communication and any attached files are Speedcast Wireless proprietary and may be legally privileged.

[experr:HC0001] unknown protocol: localhost (Windows only)
by France Baril 21 May '19

21 May '19

Hi, We have two servers with similar jetty configuration, we find that an http:request call on static works on Linux but not on Windows. HOW TO REPLICATE Add an image test.png in webapp/static Try the attached .xqm (change img-url for your server path) Copy of the .xqm function for reference: declare %rest:path('/a-test') > %rest:GET > %output:method("html") > %output:html-version("5.0") > function a-test:http-req(){ > let $img-url := 'http://localhost:8972/static/test.png' > let $http-function := function() {http:send-request(<http:request > method='get' status-only='true'/>, $img-url)} > let $http-s := xquery:fork-join($http-function) > let $http-status := $http-s//data(@status) > return <div>{$http-status}</div> > }; Test: http://localhost:8972/a-test Result on Linux: 200 Result on Windows: [experr:HC0001] unknown protocol: localhost This seemed to be security issue, but tests in multiple browsers return the same results and enabling CORS doesn't help... technically we're calling from the same domain/port... but hey we tried! If we type the value of $img-url directly in the browser, we see the image on both platforms, so the issue is not with accessing the image itself, but with accessing it with the http:send-request function. -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

db:replace() in DBA resulting in duplicates
by Zimmel, Daniel 20 May '19

20 May '19

Hello, something has gone awry in my database after a db:replace(): query: db:open('DB','/path/file.xml')/base-uri() result: /DB/path/file.xml This is as expected. The result is the replaced file. But when I query: db:open('DB')/root[@id='id']/base-uri() result is a sequence: /DB/path/file.xml /DB/path/file.xml The first result is the file before the db:replace(), the second after. Can somebody explain why db:open() with path parameter is returning one result, but without parameter two results? Database statistics say there are indeed two documents. But when I export the database, only one gets exported. This happens with db:replace() on 9.2 from the DBA browser interface. When I use the same db:replace() XQuery on 9.2 with my local database, all is well (document gets replaced, no duplicates). Settings should be the default ones. Thanks, Daniel
