Hacking in a "-d" into runtest's invocation of expect, I see this in the
log (the 1st time through):
expect: does "" (spawn_id exp0) match glob pattern "buffer_full"? no
i.e. it does indeed treat "buffer_full" as a glob pattern, rather than a
keyword.
Fixing the spelling to "full_buffer" doesn't fix the issue (log with -d
attached)
However, moving the "expect_before" line to *after* the "spawn"
invocation does: is the "expect_before" line too early?
My current belief here is that it's picking up the wrong spawn:
"spawn_id exp0" doesn't seem to be the right thing for it to be
listening on (am I right in thinking that's the "default" stdin/stout,
rather than the not-yet-spawned program?)
Have been attempting to come up with a more minimal reproducer, but
failing so far - some kind of heisenbug timing needed to expose this
issue, perhaps? Though I reliably hit it with my current setup, with:
make check-gcc check-jit -j2
[my copy of "Exploring Expect" is due for delivery at some point today,
so may have more conceptual grounding in this in a day
or so].
Thanks
