for loop zsh parse error 100% cpu
hi
im using grml-etc-core on a bit outdated debian box. and when executing the following cpu goes to 100% and i have to kill -9 zsh.
for i in 1 2 3; do zsh: parse error
i think it came up when i upgraded grml-etc-core to unstable. which version is in stable?
$ cat /etc/issue Debian GNU/Linux 3.1 \n \l

Why do you use grml-testing without using grml-stable as well? :)

Ah, pretty old box. :)
I can't reproduce the problem with zsh 4.3.6 (i686-pc-linux-gnu) and latest grml-etc-core.
Does it happen with 'zsh -f' as well?
Can you please try to downgrade to an older grml-etc-core version so we can locate the problem easier?
If you have mercurial (hg) and Debian's build stuff available you can build all the different versions on your own:
hg clone http://hg.grml.org/grml-etc-core cd grml-etc-core hg up $VERSION # where VERSION is just a tag in hg, just use the # grml-etc-core version you'd like to get debuild -us -uc
If that's not an option for you let me know and we will provide different debian packages for you.
@Frank: do you have any idea where this might come from?

it breaks with 0.3.52 where the vcs prompt stuff was introduced ( http://hg.grml.org/grml-etc-core/rev/1331f322ab7e ) thats why i upgraded actually ;)
maybe i neeed a newer version of zsh!?
thanks for the help!

Ah interesting, thanks for locating.

Looks so, but we should update the configuration as well so it works flawless with older zsh versions as well. :)

Yes!
i meant 'NO!' of course. it works with 'zsh -f'!
Alright, so definitely some kind of problem in our config.
@Frank: care to investigate on that?

@Frank: care to investigate on that?
Yes, I already tried it.
Given the code that introduces the bug:
[snip] for i in 1 2 3; do zsh: parse error [snap]
Clearly hints to something in our configuration, because that's pretty basic zsh syntax. However, I'm not sure the vcs_info() stuff is responsible here.
I can reproduce the problem with grml's config (even though on my box zsh does _not_ eat 100% CPU after that).
If I *disable* the vcs_info() code by: % zstyle 'vcs_info:*:' enable false
I _still_ get the parse error.
I cannot reproduce this with my own configuration - from which I cut'n'pasted the vcs_info() code into the grml setup. That means, I'm using the same code in my config.
I do have a suspicion, where the problem may be located.
Matthias, does this still happen for you after disabling vcs_info(): zstyle 'vcs_info:*:' enable false
I suspect you can and I'm looking at my suspicion right now.

My suspicion was correct, this should fix it (+a few cleanups): http://hg.grml.org/grml-etc-core/rev/9ef02f6cf89f
Thanks for reporting!

Package grml-etc-core version 0.3.57 is available in grml-testing and works fine for us, thanks - Frank.
Matthias, can you please let us know whether it fixes your issue as well?
