RHBA-2009:0463 - zsh bug fix update

Synopsis

zsh bug fix update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated zsh packages that fix various bugs are now available.

Description

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.
