Description Akira TAGOH 2008-06-26 05:43:30 EDT
Description of problem:
after trying "while [ 1 ]; do continue -1; done", zsh doesn't do anything except
C-d.

Version-Release number of selected component (if applicable):
zsh-4.3.4-7.fc9.x86_64

How reproducible:
always

Steps to Reproduce:
1.see above
2.
3.
  
Actual results:
no errors. and no operations after that except C-d and storing history.

Expected results:
If giving -1 to 'continue' is invalid, that should behaves like bash:
-bash: continue: -1: loop count out of range

I was able to reproduce this. I reported this upstream at:

http://www.zsh.org/mla/users/2008/msg00782.html

And, amazingly, within 24 hours on a Saturday/Sunday period a patch was posted and committed, including new tests and enhanced compatibility:

http://www.zsh.org/mla/workers/2008/msg01228.html

Seems that this bug can be marked as being fixed in upstream.

Still seeing this with F10Beta.
Comment 4 Daniel Qarras 2009-04-03 11:05:45 EDT
This is fixed in F11ß:

localhost:~> while [ 1 ]; do continue -1; done
continue: argument is not positive: -1
zsh: exit 1
localhost:~> 

Please close this one if you can.
