  • Ticket #1395 – Description

    v1 v2  
    11For 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).

    3 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).

    5 The issue might be related to releases 0.8 (2017-05-23) or 0.8.1 (2017-06-03) of scsh-process.
     5Apparently, the chicken core repo didn't have any relevant change around that time.

     7The issue might be related to releases 0.8 (2017-05-23) or 0.8.1 (2017-06-03) of scsh-process. The change in release 0.8.1 looks particularly suspicious (86310f955).

    79I'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).
