ridiculousfish	9be77d1f9c	Correctly handle "self fd redirections" ... This adds a test for the obscure case where an fd is redirected to itself. This is tricky because the dup2 will not clear the CLO_EXEC bit. So do it manually; also posix_spawn can't be used in this case.	2019-12-13 16:51:49 -08:00
ridiculousfish	d6c71d77a9	Correctly cloexec file redirections ... The IO cleanup left file redirections open in the child. For example, /bin/cmd < file.txt would redirect stdin but also leave the file open. Ensure these get closed properly.	2019-12-13 16:16:19 -08:00
