4.225. zsh

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

Bug Fixes

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