The ‘t/malformed-split.sh’ test of Texinfo 6.7 hangs on GNU/Hurd (in a childhurd) as of commit 78f03567f44f704dfbc03cb64368aa42a01e78ad.
The test invokes its ‘pseudotty’ program, which creates a pseudo-terminal using ‘posix openpt’. That call fails when not running as root in a childhurd: --8<---------------cut here---------------start------------->8--- task109(pid14826)-> 4205 (227424 0 0); 75<--117(pid14826)->io_write_request ("./pseudotty: " -1)./pseudotty: = 0 13 75<--117(pid14826)->io_write_request ("getting pty master fd" -1)getting pty master fd = 0 21 75<--117(pid14826)->io_write_request ("\n" -1) = 0 1 task109(pid14826)-> 4205 (227424 0 0); task109(pid14826)-> 4205 (227424 0 0); 86<--120(pid14826)->dir_lookup ("dev/ptyp0" 3 0) = 0x4000000d (Permission denied) 86<--120(pid14826)->dir_lookup ("dev/ptyp1" 3 0) = 0x40000010 (Device or resource busy) 86<--120(pid14826)->dir_lookup ("dev/ptyp2" 3 0) = 0x4000000d (Permission denied) 86<--120(pid14826)->dir_lookup ("dev/ptyp3" 3 0) = 0x40000002 (No such file or directory) task109(pid14826)-> 4205 (227424 0 0); task109(pid14826)-> 4205 (227424 0 0); 118<--122(pid14826)->proc_mark_exit_request (256 0) = 0 task109(pid14826)-> 4205 (227424 0 0); task109(pid14826)-> 2008 () = 0 Child 14826 exited with 1 --8<---------------cut here---------------end--------------->8--- The childhurd only has this: --8<---------------cut here---------------start------------->8--- ludo@childhurd /tmp/guix-build-texinfo-6.7.drv-0/texinfo-6.7/info$ ls -l /dev/ptyp* crw--w---- 1 root tty 0, 0 Nov 26 16:05 /dev/ptyp0 crw--w---- 1 ludo tty 0, 0 Nov 26 16:05 /dev/ptyp1 crw------- 1 root root 0, 0 Nov 26 16:05 /dev/ptyp2 --8<---------------cut here---------------end--------------->8--- Ludo’.
