Ah, the Debug.Log hang seems like it might relate to a missing
/proc/self/exe symlink -- probably because I didn't mount the /proc
filesystem. Here's the relevant bit of strace output:
[pid 7463] write(3, "[ OK ] Exception.Exception"..., 143 <unfinished ...>
[pid 13045] readlink("/proc/self/exe", <unfinished ...>
[pid 7463] <... write resumed> ) = 143
[pid 13045] <... readlink resumed> 0x7fff11d94460, 512) = -1 ENOENT
(No such file or directory)
[pid 7463] read(0, "[ RUN ] Debug.Log\n", 8192) = 23
[pid 7463] write(1, "[ RUN ] Debug.Log\n", 23[ RUN ] Debug.Log
) = 23
[pid 13045] futex(0x2aaaabaa75e0, FUTEX_WAIT_PRIVATE, 2, NULL <unfinished ...>
[pid 7463] write(3, "[ RUN ] Debug.Log\n", 23) = 23
[pid 7463] read(0,
The last two futex(...) & read(...) calls wait around forever.
Might be a silly question, but I'm guessing it's standard practice to
mount /proc when doing these chrooted builds?
And assuming the build servers are using a chroot, can I also assume
they will mount procfs on /proc prior to executing a build?
Either way, I'm going to mount /proc in my chroot & try again.
