QueryHash does not include distinct/reduced.

[Aklakan]

QueryHash produces the same hash for select queries that only differ in the distinct / reduce flags.

[Aklakan]

Fixed with Scaseco/jenax@dd87842

[Quannz]

HI Aklakan, I faced some problems compiling Jenax (commit dd87842)

Here is the error:

[Aklakan]

Hi, I removed the reference to the offending class from the develop branch.
I am currently looking into upgrading lsq to the latest snapshot.

[Aklakan]

The jenax and lsq develop branches should now build again.
Note, that jenax should be built from the jenax-bom folder, which is the 'true' parent of the project.

[Quannz]

Thanks! But the new LSQ has a problem when I run the following command (the old version of LSQ works fine): lsq rx rdfize -e http://server.from/which/the/log/is/from Test.log > file.log.trig, please find the Test.log attached.

[Aklakan]

Hi, the issue should be fixed now - both lsq rx and lsq spark variants now work for me with your test file.
Thanks for providing this as a test case.
The issue was due to an old shaded dependency of our sansa stack that replaced javax with jakarta. by now sansa has been upgraded to spark4 which is developed directly against the modern jakarta modules - so our old shaded artifact is no longer needed.
I noticed that your command generates (probably unwanted) blank nodes for the HTTP headers:

            <http://lsq.aksw.org/vocab#http://lsq.aksw.org/vocab#headers>  _:b1;
            <http://lsq.aksw.org/vocab#http://lsq.aksw.org/vocab#headers>  _:b0;

You can omit these triples by adding the --slim option:

lsq rx rdfize --slim -e http://server.from/which/the/log/is/from Test.log

[Quannz]

Hi, thanks for the quick reply!

I faced another issue while following the typical LSQ process:

lsq rx probe file.log
lsq rx rdfize -e http://server.from/which/the/log/is/from file.log > file.log.trig
lsq rx benchmark create -d myDatasetLabel -e http://localhost:8890/sparql -o > benchmark.conf.ttl
lsq rx benchmark prepare -c benchmark.conf.ttl -o > benchmark.run.ttl
lsq rx benchmark run -c benchmark.run.ttl *.log.trig

Now the first three commands work fine, but the fourth lsq rx benchmark prepare leads to the following error:

Does this work on your side? Or a problem with my setup..

[Aklakan]

There was an initialization issue (accessing Quad.defaultGraphIRI triggered Jena init, in which Quad.defaultGraphIRI was accessed triggering an NPE). Also, in LSQ itself the lsq:config property was renamed to lsq:benchmarkConfig.

I tried your commands and it now works for me. I should add them to the Makefile as a selftest goal.

Please pull lsq (develop branch) and build with the -U flag - such as mvn -U clean install (in order to update snapshot dependencies of jenax)

You can also pass -U to the make goals like this:

make deb-rere ARGS="-U" (e.g. this command rebuilds and reinstalls the debian package if you are on debian/ubuntu)

[Quannz]

I pull the LSQ (develop branch), after that I run make deb-rere ARGS="-U", then I follow the typical LSQ process:

[INFO] Benchmark run xc-myDatasetLabel_2025-09-01 completed successfully

Now the commands run without crashing, but the Test.ttl file is empty. Does the same command produce an empty file also for you?

[Aklakan]

hm with your commands I get output. But perhaps its because of my store. Is it possible to get a copy of the triple store you are testing against?
What puzzles me is that there are also blank nodes again - it seems that with the update something broke with the skolemization because all blank nodes should be replaced with IRIs. Perhaps this is also the reason for the error No local execution with id _:49f5f1f2-620d-4e27-9ad0-29816e19dddd - it looks like a blank node issue.
I will investigate further. I hope that I can solve it tonight.

Thanks! Regarding the copy of the triple store, I’m just using a random triple store: in this case, I used Tentris to load the family dataset(you can download from here you can find family-benchmark_rich_background.nt inside). The reason I’m using LSQ is that I want to extract query features directly from SPARQL itself—for example, lsqo:tpInBgpCountMin, lsqo:tpCount, parse tree and so on(As far as I know, the triple store shouldn’t influence these statistics). And it’s not the first time I’m using LSQ, and the triple store(Tentris+Family) has worked well with other SPARQL queries before.

I continued work on issue 54 branch.
There is now also an initial make selftest goal - on first glance it looks better than before - no more blank nodes in the output and repeated execution with the same benchmark run id should no longer crash; instead, already executed queries should be skipped.
So one thing is, that the ids of the queries which have been benchmarked in a specific run are stored in a TDB2 database whose location is printed on start:

[INFO] TDB2 benchmark db location: /tmp/lsq-xc-myDatasetLabel_2025-09-03

Restarting the benchmark with an existing database cause an exception.

Currently the tests are very limited, because the hashing approach and the model changed so many times.
However, in order to test the structure, a test suite based on the sparql queries from http://lsq.aksw.org/v2/usage/useful-queries.html could be added - so running these queries on the output should still produce non-empty results.
Will continue tomorrow with that.

The issue-54 branch with the latest dependencies also produces two graphs instead of one for the Test.log file:

}

}

The s._ in the hash stands for plain SELECT, s.d for SELECT DISTINCT.
