Add reference to result files and log files to results XML

[dbeyer]

I propose to add to the BenchExec results XML file a column (or attribute) that links the run to its results files and the log file.
Like in a database, an object in a table should have a foreign key that points to another object in a different table if it depends on this.

From the <result> tag, it is not clear how to identify the results or log files:

<result benchmarkname="jbmc" date="2026-02-24 19:45:08 CET" starttime="2026-02-24T19:46:23.869863+01:00" tool="JBMC" version="6.8.0 (cbmc-6.8.0-10-g4767cf5d65)" toolmodule="benchexec.tools.jbmc" generator="BenchExec 3.35-dev" displayName="JBMC" memlimit="3000000000B" timelimit="900s" cpuCores="1" options="--graphml-witness witness.graphml" block="Java.no-runtime-exception.Main" name="SV-COMP27_no-runtime-exception.Java.no-runtime-exception.Main" endtime="2026-02-24T20:39:49.605286+01:00">

For example, consider the following <run>:

  <run name="../sv-benchmarks/java/jayhorn-recursive/SatFibonacci02.yml" files="[../sv-benchmarks/java/common, ../sv-benchmarks/java/jayhorn-recursive/SatFibonacci02]" properties="no-runtime-exception" propertyFile="../sv-benchmarks/java/properties/no-runtime-exception.prp" expectedVerdict="true">
    <column title="cputime" value="0.972704s"/>
    <column title="host" value="apollon030"/>
    <column title="memory" value="47448064B"/>
    <column title="status" value="true"/>

The result files are stored in the folder
./jbmc.2026-02-24_19-45-08.files/SV-COMP27_no-runtime-exception/SatFibonacci02.yml/

I propose to add a column:

    <column title="result_files" value="./jbmc.2026-02-24_19-45-08.files/SV-COMP27_no-runtime-exception/SatFibonacci02.yml/" hidden="true"/>

Alternatively, this could be an attribute for the <run> tag instead of a child <column>.

Similar for the log file.

Currently, the missing information requires complicated post-processing, composing the path in a hard-coded manner
as the concatenation by delimiter . of the following attributes of <result>:

• the benchmarkname
• the date="2026-02-24 19:45:08 CET", after removing CET and replacing : and
• the constant files
• then a subdirectory consisting of
• the name of the result
• then a subdirectory of
• the name of the <run> tag, by removing directory prefix from it (because name is a file path)

An alternative way is to use the name of the XML file jbmc.2026-02-24_19-45-08.results.SV-COMP27_no-runtime-exception.Java.no-runtime-exception.Main.xml.bz2:

• extract the prefix until the constant results
• then replace results by files,
• then a subdirectory consisting of
• the name of the result
• then a subdirectory of
• the name of the <run> tag, by removing directory prefix from it (because name is a file path)

This can be avoided by adding to the the explicit knowledge of where its results (and log file) are located.

Thanks for the comprehensive writeup. I agree.

I would prefer it as attribute to <result>. And maybe there is even a way to unify the paths to result files and the log, as they are quite similar (all the dynamic parts that derive from user input are the same).

Once we do this we could plan doing #8 as the backwards compatibility there would then be a smaller problem, because people can use the precomputed path.

For working with old and new result files conveniently we could add a utility for backfilling these attributes into old results files.
