Hi Santiago, I've been banging my head a fair part of the day wondering why the error seemed to never occur when I was staring at it. My current conjecture would be to look at what happens when stressing the entropy pool of the machine, as the random source seems to behave slightly differently depening on real and virtual hosts. At the moment, I have had the build hanging twice in a row at the same stage of documentation building, while trying to stress the entropy pool with:
$ cat /dev/random >/dev/null
The build froze in deadlock at the following command in the two
cases:
/build/reproducible-path/scilab-2024.1.0+dfsg/scilab/.libs/scilab-bin
-nb -noatomsautoload -nouserstartup -quit -f
./modules/helptools/data/configuration/regen_list.sce -nw
I have two reserves:
0. if I trust Helmut Grohne, I cannot empty the entropy pool;
maybe I can just make it more strained, so the behavior may
be unreproducible to some extent: for instance I have not
managed to reproduce the behavior straight on my laptop;
1. the error occurs slightly earlier in the build log than your
own records, so I may have triggered a different issue with
my meddlings;
2. I probably want to try this procedure a couple more times,
to determine a more precise frequency of occurrence (I could
have run into "coincidences" so far, a third iteration in a
row would be "enemy in action").
I may continue after a good night of sleep, to at least
determine whether this is a real clue or just a dead end. If
the former, then this would point to either an implementation
issue in scilab making it too fragile on the random source, or a
problem in the kernel's random source itself, since the behavior
has occurred more often with recent kernels, or a bit of both.
Have a nice day, :)
