|Hi, | |I've got another bug report from one Fedora user. When whence builtin is used |with -q option it hangs. Whence was modified a lot between 2008-02-02 and |2008-07-25. New version uses while(pp) loop but for Q_FLAG pp never changes |causing ksh loop forever. I've just added pp = 0 to Q_FLAG if-section and it |seems working fine: | --- src/cmd/ksh93/bltins/whence.c +++ src/cmd/ksh93/bltins/whence.c 2010-04-29 12:03:22.744013139 +0200 @@ -234,7 +234,10 @@ static int whence(Shell_t *shp,char **ar } } if(flags&Q_FLAG) + { r |= !cp; + pp = 0; + } else if(cp) { if(flags&V_FLAG) |Btw, when looking in the code it seems tofree variable is never checked when |Q_FLAG is used and also in the loop this value is sometimes set to 1, but |never zeroed once it is set, is it expected? | |Regards, |Michal Hlavinka |_______________________________________________ |ast-developers mailing list |ast-developers@research.att.com |https://mailman.research.att.com/mailman/listinfo/ast-developers
