Error QProcess: Destroyed while process is still running

Question

Edit: I discovered that the problem is not related with the script cited below, but I'll leave it there just for history.

Well, this error appears when I close texstudio with the viewer open (xdvi or evince). If I close the viewer first and then close texstudio, no problem, no errors on the terminal.

This is the error:

QProcess: Destroyed while process is still running.

---

Old text: Every time when I close my texstudio after opened by my script below I got this error on the terminal:

QProcess: Destroyed while process is still running.

Here is the script fastex.sh

#!/bin/sh

# Copyleft 2012 by Sigur

caminho=/home/$USER
file=$caminho/fastex-temp
exec 3>&1
exec > "$file".tex
printf '\\documentclass[11pt,a4paper]{amsart}\n' 
printf '\\usepackage{amsfonts,amsthm,amsmath,amssymb}\n' 
printf '\\usepackage[latin1]{inputenc}\n' 
printf '\\usepackage[T1]{fontenc}\n' 
printf '\usepackage{tikz}\n'
printf '\usepackage[brazil]{babel}\n'
printf '\n' 
printf '\\begin{document}\n' 
printf '\n'
printf '\\end{document}' 

linha=$(wc -l < "$file".tex)
texstudio --line $linha  "$file".tex
find . -name  "fastex-temp.*" | grep -vP '.tex$|.pdf$' | while read -r i; do rm $i; done

I guess that the problem is with the find command to delete auxiliary files. So, is find executed only after I close texstudio?

Thanks for a while. Best wishes.

Answer 1

I tried your script, with latest (2.4) version there was no problem,

If you forget to terminate the QProcess before closing main window of your program, you usually get this warning, I think the author has fixed that problem:

QProcess: Destroyed while process is still running.

texstudio doesn't release the pesudo tty when it's started, so deleting of files only start after texstudio quits.

And to remove files, it could be saved to one line:

find . -name "fastex-temp.*[^(tex|pdf)]" -exec rm {} \;

EDIT

To test if the above command works fine, copy and run the following script:

DIR=$(mktemp -d) 
cd ${DIR}
touch fastex-temp.{aa,tex,pdf,bb}
find . -name "fastex-temp.*[^(tex|pdf)]" -exec rm {} \;

Now execute the command above and you would see only *.tex and *.pdf is left here.
