Description

Hello there, I think i found a problem with export Gantt to PNG. When I have task's subject with escape characters for example: "Student's Problems with new login page" I receive error (from Redmine logs):

MiniMagick::Error (`convert -size 1125x926 xc:white -stroke transparent -fill black -stroke transparent 
...
-strokewidth 1 -draw text 84,418 'Student'"'"'s Problems with new login page' -fill 
...
red -draw line 516,36 516,925 /tmp/mini_magick20200929-4913-1ne7j9r.png` failed with error:
convert-im6.q16: non-conforming drawing primitive definition `'' @ error/draw.c/RenderMVGContent/4301.
):

lib/redmine/helpers/gantt.rb:381:in `to_image'
app/controllers/gantts_controller.rb:44:in `block (2 levels) in show'
app/controllers/gantts_controller.rb:42:in `show'
lib/redmine/sudo_mode.rb:65:in `sudo_mode'

And when I except this task by filters from Gantt everything is fine. Is there any chances to fix this issue?

It used Redmine::Utils::Shell.shell_quote to escape the subject string, but it was an escaping for the string that cannot be handled by the magick-convert command.
I fixed the special character escaping process as follows.

This issue seems superseded and fixed by #38728. Can someone test and confirm this? Especially 'mswin' compatibility might be an issue...

Holger Just: care to chime in?

Hello,
Unfortunately can't test it, as already this instance is out of my touch.
But anyway, thanks for supporting it.
