Message 96405 - Python tracker (original) (raw)

The undocumented (but unit tested!) pipes.quote does not correctly escape '!', which cannot be passed to the shell outside of single- quotes:

sh-3.2$ python Python 2.6.1 (r261:67515, Jul 7 2009, 23:51:51) [GCC 4.2.1 (Apple Inc. build 5646)] on darwin Type "help", "copyright", "credits" or "license" for more information.

import pipes pipes.quote("omgshoes!") 'omgshoes!'

sh-3.2$ echo "omgshoes!" sh: !": event not found

bash-3.2$ echo "omgshoes!" bash: !": event not found

zsh-4.3.9% echo "omgshoes!" dquote>

This needs to be single-quoted for safety:

sh-3.2$ echo 'omgshoes!' omgshoes! bash-3.2$ echo 'omgshoes!' omgshoes! zsh-4.3.9% echo 'omgshoes!' omgshoes!
