CUTEstModel - Path with blank spaces

[leonardosecchin]

Hi, I am using Julia 1.5.3. The routine "CUTEstModel" apparently does not handle paths containing blank spaces when reading a SIF file. Sincerely, Leonardo.

Hi @leonardosecchin, thanks for the issue. I have a few clarification questions:

You're trying CUTEstModel("PATH TO FILE")? Can you post an example and the output? Is it a separate .SIF file that you have, or one of the shipped ones?

Hi, I executed "nlp = CUTEstModel(sifdir[i]);", where "sifdir[i]" is a string provided by "readdir" command. Here is the output. I printed the complete path to the sif file (it exists!) from Julia. I notice that no "basename" command is executed...

This is the complete path to SIF file: /home/leonardo/Dropbox/UFES/Otimizacao 2/julia/sif/AKIVA.SIF

basename: operando extra “.SIF” Tente "basename --help" para mais informações.

Makes sense, I'll have to take a look to see whether it's inside CUTEst.jl or just CUTEst. In the meantime, can you use the SIF problems downloaded automatically by CUTEst.jl? nlp = CUTEstModel("AKIVA") for instance, should work.

[leonardosecchin]

If the environment variable MASTSIF has no blank spaces, CUTEstModel works. Otherwise, an error "xxxx.SIF not found" occurs. I believe that this does not depend on whether we use the path of the problems automatically download by CUTEst.jl (where there are probably no blank spaces) or a particular path.

Hello again. I've tried to run CUTEst directly and it fails too, so it's not an issue with the Julia wrapper, but with the sifdecoder code.

Example:

sifdecoder "Some dir/AKIVA.SIF" 
basename: extra operand ‘.SIF’
Try 'basename --help' for more information.

 ERROR: file .SIF is not known in directories
 .
dir or $MASTSIF

I went into the sifdecoder script and changed

-251   PROBNAME=`basename $PROBLEM .SIF`
+251   PROBNAME=`basename "$PROBLEM" .SIF`
-252   PROBDIR=`dirname $PROBLEM`
+252   PROBDIR=`dirname "$PROBLEM"`

-400   $LN -s $PROBDIR/${PROBNAME}.SIF ./$TEMPNAME.SIF
+400   $LN -s "$PROBDIR/${PROBNAME}.SIF" ./$TEMPNAME.SIF

and apparently, it works. I just don't know a good way to test it. @dpo, do you?

Fixed with the release v0.13.3. The decoder is now a binary and not anymore a shell script. We have a new dependency for it (SIFDecode_jll.jl).
