Martijn Dekker 045fe6a110 Fix: Closing a FD within a comsub broke output (rhbz#1116072) ... Another Red Hat patch. "Prior to this update, the result of a command substitution was lost if a file descriptor used for the substitution was previously explicitly closed. With this update, ksh no longer reuses file descriptors that were closed during the execution of a command substitution. Now, command substitutions work as expected in the described situation." Prior discussion: https://bugzilla.redhat.com/1116072 Original patch: 642af4d6/f/ksh-20140929-safefd.patch src/cmd/ksh93/include/io.h, src/cmd/ksh93/sh/io.c: - Add sh_iosafefd() function to get a file descriptor that is not in use or otherwise occupied (including marked as closed). src/cmd/ksh93/sh/subshell.c: sh_subshell(): - Use that function to obtain a safe FD upon restoring state when exiting a command substitution. I don't really know the how and why -- all that I/O magic is still beyond me and the code is uncommented as usual. src/cmd/ksh93/tests/subshell.sh: - Add regression test from the reproducer in the bug, reduced to the minimum necessary.		2020-09-27 04:46:24 +02:00
