This is the failing test: https://gitlab.com/nbdkit/nbdkit/-/blob/77c9bad77a663726d424972e1dc73d4f06b005bb/server/test-public.c#L142 testing this function: https://gitlab.com/nbdkit/nbdkit/-/blob/77c9bad77a663726d424972e1dc73d4f06b005bb/server/public.c#L360

I'm not immediately sure why it would fail. Is this not glibc or an otherwise unusual libc configuration? How about the C compiler, is it not gcc? Is it a 64 bit machine?

check() fails for me, too:

/bin/sh is a symlink to bash.

Can you see if this fixes it? https://gitlab.com/nbdkit/nbdkit/-/commit/99712c09835ae430912aed4848579fdfab01a576

Great work.

rwmjones commented on 2023-10-09 07:32 (UTC)

It's actually that we use system(3) to run the external scripts which runs /bin/sh, so bashisms shouldn't be used in those parameters (logscript and --run, in the case of this test). It is an upstream bug so I'll see if I can fix this ...

rvalles commented on 2023-10-09 06:47 (UTC)

Update: Based on the error log, I linked /bin/sh to /bin/bash (back from dash), and the test passed.

Thus this is an upstream issue; their scripts are calling sh when they should be calling bash.

I suspect unfortunately this may be an OCaml 5 issue. The whole locking architecture is different because of multicore. We've not even started looking at OCaml 5 yet.

I can only reproduce the test-ocaml-errorcodes issue. It fails with "Fatal error: Fatal error during lock: Resource deadlock avoided" which happens in the call to LEAVE_BLOCKING_SECTION_FOR_CURRENT_SCOPE() in open_wrapper() in plugins/ocaml/plugin.c.

It also happens on older versions of nbdkit. Maybe ocaml 5.0.0 is the trigger.
