Hi,
In a French mailing-list, I've just heard of a bug related to
recursive function calls, source and exit; I don't think it has
been reported yet. Here's a way to reproduce it:
dixsept:~> zsh-beta -f
dixsept% echo $ZSH_VERSION
4.3.0-dev-1
dixsept% echo false > ./file
dixsept% f() {
function> echo $[++i]
function> cat file
function> sleep 1
function> . ./file || echo exit > ./file
function> f
function> }
dixsept% which f
f () {
echo $[++i]
cat file
sleep 1
. ./file || echo exit > ./file
f
}
dixsept% f
1
false
2
exit
3
exit
4
exit
5
exit
6
exit
[Ctrl-C]
dixsept:~>
FYI, bash doesn't have this problem:
[...]
vlefevre@dixsept:~$ f
1
false
2
exit
dixsept:~>
