Bug Fix Advisory zsh bug fix update

Advisory: RHBA-2009:0463-2
Type: Bug Fix Advisory
Severity: N/A
Issued on: 2009-05-06
Last updated on: 2009-09-02
Affected Products: Red Hat Enterprise Linux (v. 5 server)
Red Hat Enterprise Linux Desktop (v. 5 client)

Details

Updated zsh packages that fix various bugs are now available.

The zsh shell is a command interpreter usable as an interactive login shell
and as a shell script command processor. Zsh resembles the ksh shell (the
Korn shell), but includes many enhancements. Zsh supports command line
editing, built-in spelling correction, programmable command completion,
shell functions (with autoloading), a history mechanism, and more.

These updated zsh packages provide fixes for the following bugs:

* when running a large number of processes, it was possible for duplicate
PID numbers to enter the job table. Under certain conditions, zsh would
wait forever for a process with the same PID as another, finished process,
to itself finish. With these updated packages, zsh is now able to determine
when jobs with the same PID numbers are both finished, or not, or one is
and not the other. (BZ#465455)

* zsh code blocks which started with the "$(" sequence and ended correctly
with a closing parenthesis ")", but which contained comments, were parsed
incorrectly. This has been fixed so that "$(..)" blocks which contain
comments are still parsed correctly, thus resolving possible syntax errors
in zsh commands and scripts. (BZ#484348)

All users of zsh are advised to upgrade to these updated packages, which
resolve these issues.
