Description (last modified by )
For some months now scsh-process' tests have been randomly hanging on the Linux salmonella machines (maybe also on the FreeBSD machine?). When the test script hangs, it blocks the whole salmonella execution. On the Linux salmonella machines, it hangs at least twice per week (that's a very conservative estimate).
I think the problem started around 9 of June. I realized it on the 14th (I know that because I checked the IRC log when I mentioned that). We have a gap between 9 and 14 in the salmonella linux x86-64: https://salmonella-linux-x86-64.call-cc.org/master-debugbuild/gcc/linux/x86-64/2017/06/ (I probably only realized the hang on the 14th).
The issue might be related to releases 0.8 (2017-05-23) or 0.8.1 (2017-06-03) of scsh-process.
I've installed a hack on the Linux salmonella machines to periodically check if scsh-process' test script is hanging and kill the parent of the defunct process (see ec0cffb94f in the chicken-infrastructure repo).
The bad news is that I cannot reproduce the issue on my machine. I tried to run csi -s run.scm < /dev/null > /dev/null 2>&1 in a loop and it ran flawlessly for more than 3500 iterations.
