Deploying BaseX + data + client
by Jonathan Robie 25 May '18

25 May '18

I have written a Python package for querying Greek syntax from Jupyter Notebook. It relies on BaseX and one or more open data resources found in GitHub repositories. I want to make it available to the public in a way that is easy to install. One possibility is to write a Python script that uses Docker to install BaseX, retrieves the data and installs it in the desired directory structure - perhaps in the container, then loads it into the database. I assume that would work cleanly cross-platform? Are there better approaches that I should consider? Are there security considerations that I should consider? Jonathan

Duplicate files when using webDAV and batch processes
by France Baril 25 May '18

25 May '18

Hi, We've been having this issue for a while and we think resolving it may be the key to resolving an intermittent server 500 error that we've been having. When a user tries to save a file while a batch process is running, BaseX saves duplicates of the file. How to reproduce: 1) Take a fresh BaseX 9.0.1 installation 2) Copy the attached .xqm in webapp 3) Create an empty DB called mydb 4) Access localhost:port-num/test/create-update-a-lot-of-files to populate your db. 5) In OxygenXML, set a webdav connection to the db and open a file, add a character in one of the elements, but don't save the file. 6) From the browser, access 'localhost:port-num/test/update-something' 7) While the process in the browser is still running, save the file in Oxygen. You'll get a message saying that read timed out. Click ok and do not try saving the file again. 8) When the update-something process is done running, don't resave the file in Oxygen, instead go to localhost:port-num/test/oups-duplicates. You'll get a message saying that some files are duplicated. If you don't try again from step #4 a few times. You'll only get duplicates if you get the time out message before the update-something process is still running. If you try to save the file many times, you'll get more duplicates, 4 or 6. We're not sure if it's a BaseX bug or if we are setting our user management and/or locking rules incorrectly. Do you have any suggestions? -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Hi Ветошкин (cc to the list), Maybe we find a way to speed up your queries; you can attach them to your next mail. I guess that the parallel query execution leads to "random access patterns" on disk. You can enforce one query at a time by setting the PARALLEL option to 1 (see [1]).

Atomization
by Giuseppe Celano 24 May '18

24 May '18

I think I have identified a problem with atomization of attribute content (no database involved). I have a simple query: for $s in doc("doc1")//s//t for $d in doc("doc2")//case where $d/verb_lemma = $s/@l and $d//verb_form/@value = $s/@f and $d/aspect-values/@sign = "yes" return $s In order to get a result, I (necessarily) need to use the data() function in data($d/aspect-values/@sign) = "yes", otherwise the query never returns a result. Is this a bug? I would expect that the value of @sign is automatically atomized and compared to "yes", but this does not seem the case. Thanks.

New BaseX setup
by France Baril 23 May '18

23 May '18

Hi, In one of my projects, we are trying to refactor our code so it uses a node.js client. We have extensive functions that do more than just get data in our .xqm. They were implemented around the http server and our web application was calling the REST functions we implemented using jquery AJAX request. All the examples we looked at in the documentation that don't use the http server pass entire queries as a string to the server. We were wondering if we can call functions from our .xqm modules directly (ex. namespace:do-this(param0, param1)) or if any request that uses functions from our .xqm files need to pass through the rest API. If we can call our .xqm functions more directly, could you point us to an example to help us understand how it would work? Thanks! -- France Baril Architecte documentaire / Documentation architect france.baril(a)architextus.com

Dear list, I tried to insert a huge XML document (english wikipedia). When doing so and using the default parser I got the following warning: "/my/path/enwiki-latest-pages-articles.xml" (Line 61696838): JAXP00010004: The accumulated size of entities is "50,000,001" that exceeded the "50,000,000" limit set by "FEATURE_SECURE_PROCESSING". I solved this by setting the environment variables: -DentityExpansionLimit=2147480000 -DtotalEntitySizeLimit=2147480000 -Djdk.xml.totalEntitySizeLimit=2147480000 So it seems this is a security measure from JXB. Would it be possible to set these values by default or at least be able to change the limit with the GUI or BaseX options?

about special characters
by BitRider001 22 May '18

22 May '18

Hi, I just joined the mailing list due to a problem I'm having displaying and storing special characters. I started with a CSV and created a database from it and the CSV is in UTF-8. However, when I query the special characters become garbled. I'm using the GUI in Windows 10. It starts with this in the CSV: <name>Cañelas</name> Then ends up with this when I export the query result into a text file: <name>ï£¼Caï¿½ï£¼las</name> Help please. Bit
