However: this poll implementation, while compiling OK, doesn't work properly.
Because it uses recv(...,MSG_PEEK), it works on sockets only (returns ENOTSOCK
on anything else), while the real poll() works on all
kind if file descriptors, at least that is my understanding.
Here on HP NonStop, when being connected via an non-interactive SSH, we get a
set of pipes (stdin, stdout, stderr) instead of a
socket to talk to, so the poll() just hangs/loops.
As git's implementation is based on ('stolen' from?) gnulib's and still pretty
similar, CC to the gnulib list and Paolo
Any idea how this could get solved? I.e. how to implement a poll() that works
on non-sockets too?
There is some code that pertains to a seemingly similar problem in Mac OS X,
but my problem is not identical, as that fix doesn't
