Package: zsh
Version: 4.3.15-1
Severity: normal
The suspend (^Z) behavior while a function is running is unclear.
The documentation (man pages) should describe the behavior. There
may be a bug in zsh, as some other shells don't behave in the same
way.
Consider:
foo() { emacs "$@"; d=`date`; echo "$d"; }
and the following test under X (so that Emacs uses its own window,
or you can try with another X application):
1. Run foo.
2. Type ^Z in the terminal.
3. Type: fg [Return].
4. Quit Emacs.
5. Type: echo "$d" [Return].
With zsh, the whole function is suspended. The effect is that zsh is
forked (this is not documented, though can be guessed), thus $d will
not be set in the main shell (Step 5: nothing is displayed).
With bash, dash, mksh and pdksh, only the emacs process is suspended.
With ksh93, the ^Z is ignored until Emacs is quit, then the function
is suspended, with the same effects as in zsh. With posh, the whole
shell is suspended.
