Currently the forced progress in RunTool is trying to fit the output
line into a terminal width, but it doesn't take into an account a
situation when the terminal width is reported as zero. This manifests
when running in docker image with redirected output and can be seen
in the github workflow output for esp-idf-ci-action.
docker run --rm -t my_ubuntu_esp python3 -c 'import os,sys; print(os.get_terminal_size(), sys.stdout.isatty())'
os.terminal_size(columns=238, lines=59) True
vs
docker run --rm -t my_ubuntu_esp python3 -c 'import os,sys; print(os.get_terminal_size(), sys.stdout.isatty())' | tee
os.terminal_size(columns=0, lines=0) True
Since the output is reported as tty and the terminal width as 0, the
fit_text_in_terminal() function returns empty string. I also verified this
by running idf.py build inside a testing docker image.
This fix adjusts the fit_text_in_terminal() function to return original
line if the terminal width is zero.
Also simplify the progress print and use same approach as ninja
