Subject: Fwd (potential regression in 5.0.3): Bug#732726: zsh function freeze
Date: Fri, 20 Dec 2013 20:24:35 +0100 [thread overview]
Message-ID: <20131220192435.GE27889@sym.noone.org> (raw)
Hi,
this has been reported[1] against zsh 5.0.3 in Debian today. Looks like
some regression in 5.0.3 on a first glance. Maybe related to the
test-suite freezes which have been reported on a few architectures.
[1] http://bugs.debian.org/732726
Since 5.0.4 seems close, I thought I'd better forward it soon despite
I haven't looked at it closer yet.

Package: zsh
Version: 5.0.3-1
Severity: important
This is an important regression (no problems after downgrading to
5.0.2-6), always reproducible.
With a private SVN repository, "svncdiff -c65935 ~/wd | head" freezes, where
svncdiff is the following zsh function (I have "autoload -U svncdiff"):
------------------------------------------------------------------------
#!/usr/bin/env zsh
# Wrapper to "svn diff", written by Vincent Lefevre <vincent@vinc17.org>
# Needs my tdiff utility to process the diff output; otherwise you need
# to remove the "| tdiff" at the end.
# Example of svncdiff usage:
# svncdiff -5 -x -p file
# for 5 lines of unified context and function information.
emulate -LR zsh
local -a args xopt
setopt EXTENDED_GLOB
while [[ $# -ge 1 ]]
do
if [[ "x$1" == x-[0-9]# ]] then
args=($args --diff-cmd diff)
xopt=($xopt -U${1[2,-1]})
elif [[ $# -ge 2 && "x$1" == x-x ]] then
shift
xopt=($xopt $1)
else
args=($args $1)
fi
shift
done
[[ $#xopt -ge 1 ]] && args=(-x "$xopt" $args)
svnwrapper diff "$args[@]" | tdiff
# $Id: svncdiff 38442 2010-08-05 11:41:16Z vinc17/ypig $
------------------------------------------------------------------------
The dependencies can be found on <https://www.vinc17.net/unix/>.
When svncdiff is called as a script, this is no such problem.
With my tps utility, I can observe:
10987 sshd: vlefevre@pts/2
└─> 10988 -zsh
└─> 11262 -zsh
├─> 11264 zsh -f -- /home/vlefevre/bin/svnwrapper diff -c65935 /home/vlefevre/wd
│ └─> 11269 svn diff -c65935 /home/vlefevre/wd
│ ├─> 11273 zsh /home/vlefevre/scripts/ssh mysvn svnserve -t
│ │ ├─> 11295 cat
│ │ └─> 11298 ssh -F /home/vlefevre/.ssh/config -C mysvn svnserve -t
│ └─> 11299 zsh /home/vlefevre/scripts/ssh mysvn svnserve -t
│ ├─> 11317 cat
│ └─> 11320 ssh -F /home/vlefevre/.ssh/config -C mysvn svnserve -t
└─> 11265 perl /home/vlefevre/bin/tdiff
I think that this occurs on big changesets.
$ svncdiff -c65935 ~/wd | wc
2166 14746 212680
I'll try to investigate, but any idea about which zsh change could
trigger the problem?

Indeed I can reproduce it with:
svncdiff -c 8540 svn://scm.gforge.inria.fr/svn/mpfr/trunk | head
