Martijn Dekker 4ce486a7a4 Fix hang in comsubs (rhbz#1062296) (re: 970069a6) ... The new command substitution mechanism imported in 970069a6 from Red Hat patches introduced this bug: backtick-style command substitutions hang when processing about 117KiB of data or more. It is fixed by another Red Hat patch: 642af4d6/f/ksh-20140415-hokaido.patch It saves the value of the shp->comsub flag so that it is set to 2 (usually meaning new-style $(comsubs)) in two specific cases even when processing backtick comsubs. This stops the sh_subtmpfile() function in subshell.c from creating a /tmp file. However, I think that approach is quite ugly, so I'm taking a slightly different one that has the same effect. src/cmd/ksh93/include/defs.h, src/cmd/ksh93/sh/subshell.c: - Redefine sh_subtmpfile() to pass the comsub flag as an argument. (Remove the shp pointer argument, which is redundant; a pointer to the shell state can easily be obtained in the function.) src/cmd/ksh93/sh/xec.c: sh_exec(): - Apply the Red Hat fix by passing flag 2 to sh_subtmpfile(). src/cmd/ksh93/tests/subshell.sh: - Move regress test from ce68e1be from basic.sh to here; this is the place for command substitution tests as they are subshells. - Add regress test for this bug. All other changed files: - Update sh_subtmpfile() calls to pass on the shp->comsub flag.		2020-09-24 06:07:12 +02:00
