Heavily garbled text output

[yarikoptic]

E.g. looking at fail2ban repository (gitinspector 0.4.3 from debian) result of running these commands:

 git clone git://github.com/fail2ban/fail2ban
 cd fail2ban
 gitinspector --grading

looks like

more info -- what is happening is that my terminal size is 111x53 and progressbar indicator from gitinspector starts to climb up ruining previous lines in various spots and even climbs higher than original point where gitinspector was executed

[adam-waldenberg]

What terminal and shell is this under? I recently changed the behavior of how the progress bar is outputted (using \r). Could you try the master branch version and see if there is a difference?

[yarikoptic]

Was a released version as shipped in debian proper (the latest release). I will check later today the master

with master 6.20160114-57-gdaf852e the issue is better but not fixed fully:

(venv)                                                                          Statistical information for the repository 'git-annex' was gathered on 2016/01/19.

As you can see that "Below" injection I have reported in #102 and then "Statistical information ..." one sitting 1 line above where original shell prompt was

[adam-waldenberg]

Ok. I'm guessing this is a terminal and/or shell issue. I run Debian myself and have no issue. What terminal and shell are you using? With that, I may be able to reproduce it and create a workaround.

[yarikoptic]

Zsh under urxvt. I will check home in different shell/terminal

I just tried rxvt with bash; same problem. It breaks in this terminal. At least the progress bar updates correctly.

The culprit is the terminal.clear_row() function which seems to break in this terminal. It looks like this terminal parses the \b (backspace) code beyond column zero on the current line and jumps up to the previous line.

I'll see if I can solve this differently in order not to break things in this terminal.

[adam-waldenberg]

Done. The fix above should resolve it.
