Description of problem: Attempts to use process substitution result in a "syntax error". Version-Release number of selected component (if applicable): ksh-20100202-1.fc12.x86_64 (Version JM 93t+ 2010-02-02) How reproducible: Extremely easily reproducible. Steps to Reproduce: 1. Fire up a korn shell (ksh) 2. Type "cat <(echo yay)" Actual results: I get "-ksh: syntax error: `)' unexpected" Expected results: If it works, you should see "yay". Additional info: I don't think this is an inherent problem with the libraries or kernel, as I copied an older version of ksh (Version M 93s+ 2008-01-31 of FC7 vintage) and the process substitution worked just fine.
this is odd, I can reproduce this bug with ksh-20100202-1.fc12.x86_64 but can't reproduce it with local build a)some patch breaks this b)some hidden buildrequire looking into this...
b) is correct and it's pretty well hidden, I've tried to specify ALL -devel packages I have as buildrequires and it still does not work. It was broken with mock containing older libraries then on my system (reported package) and is broken with actual mock (scratch rebuild), so problem is not caused by package version differencies. ldd shows no differencies, build log shows no differencies and also strace shows nothing usable. Still, something is different here I need to experiment little more.
and the winner is... mock chroot this feature is enabled only if /dev/fd/ directory exists and works as expected. Tested with following command: ls /dev/fd/9 9<&0 >/dev/null 2>&1 but it does not work in chroot. building fix...
fixed since ksh-20100309-1.fc12 detection of /dev/fd/X was changed to /proc/self/fd/X which works in mock
