[bug#63943] [PATCH 0/5] Update Fibers to 1.3.1

[Ludovic Courtès]

Hello!

This is the much anticipated upgrade of Fibers to 1.3.1, which among
other things brings a libevent backend, making it usable on non-Linux
systems.

To me it’s important so we can upgrade the Shepherd in use on GNU/Hurd
(it’s still stuck at 0.8 because so far Fibers lacked support for
non-Linux systems), which in turn means we can use the newer Shepherd
APIs in its config file.  Unfortunately, while shepherd cross-builds
and runs on GNU/Hurd, I’m not confident it “works”.  I’ll write more
in a separate message.

There’s still one users of ‘guile-fibers-1.1’: ‘guile-gemini’.  It
can probably run on Fibers 1.3 but I don’t think it has tests for
that.

Thoughts?

Ludo’.

The patch I ended up not including in this series is use of current
Shepherd on GNU/Hurd (attached).

Problems that I see are:

  • ‘networking’ gets stuck in ‘starting’ state.  My guess is that it
    uses ‘system*’ (the replacement provided by shepherd) and that one
    does not return because we never get SIGCHLD.

  • (@ (ice-9 threads) all-threads) says there are two threads.  That
    was already the case with 0.8, but it’s no good.

Also, I haven’t tried to run the Shepherd’s test suite natively on
GNU/Hurd; I’m sure it’d uncover problems.

Overall, I’m pessimistic about signal handling without ‘signalfd’.  We
could try to get shepherd to kinda work without ‘signalfd’ (we could
even test that code path on GNU/Linux), but that’s going to be brittle
as we can already see.

What d’ya think, comrades?

Ludo’.

It would be great, if it works ;-)

While I'd like to test it and I'm still making progress building
natively on the Hurd but it's hard to predict when I'll get to building
fibers:

most (all?) of these dependencies are on my list working towards
a self-hosting guix.

Finally up to guile-fibers@1.3.1, I broke off the test suite after 2h.

I'll retry using --verbosity=2 during the night (hopefully today or
tomorrow).

Looks good to me, [1] is looking good as well.
