RHBA-2012:0274 - zsh bug fix update

Synopsis

zsh bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated zsh packages that fix three bugs are now available for Red Hat Enterprise Linux 5.

Description

The zsh shell is a command interpreter which can be used 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.

This update fixes the following bugs:

  • Prior to this update, the compdef utility prevented more than three commands from using one completion service. As a consequence, compdef failed with the error message "unknown command or service: mount". This update corrects the underlying source code so that now more than 3 commands can use one completion service. (BZ#700722)

  • Prior to this update, zsh could, under certain circumstances, keep the Process ID (PID) of terminated or suspended processes in the jobs list. As a consequence, zsh waited infinitely for already terminated or suspended processes. This update no longer returns the terminated PID and zsh now runs as expected. (BZ#706029)

  • Prior to this update, zsh could be interrupted when running the fork() option if the malloc arena was still locked. As a consequence, zsh could become indefinitely suspended when the malloc() function got called. With this update, signals are queued before the fork to avoid interruptions. (BZ#733582)

All users of the zsh shell are advised to upgrade to these updated packages, which fix these bugs.
