Re: rcs configure hang

[Kelly Wang (kellythw)]

Hi Paul,

With the conftest.c you provided, strace still hang.
Check for how many calls for chdir("confdir3"), it only has 110 times, then 
hang after mkdir("confdir3", 0700 ...
Is there any directory limitation that can make on a server?
  
sjc-ads-7913:/ws/kellythw-sjc/rcs_try/getcwd-test% tail tr
chdir("confdir3")                       = 0
mkdir("confdir3", 0700)                 = 0
chdir("confdir3")                       = 0
mkdir("confdir3", 0700)                 = 0
chdir("confdir3")                       = 0
mkdir("confdir3", 0700)                 = 0
chdir("confdir3")                       = 0
mkdir("confdir3", 0700)                 = 0
chdir("confdir3")                       = 0
mkdir("confdir3", 0700

% grep 'chdir("confdir3")' tr | wc -l
110

Thanks,
Kelly

    How many chdir("confdir3") calls were there, exactly? On my platform there 
were 
    1367.

    My guess is that the getcwd system call hung on your platform, which 
suggests a 
    kernel or filesystem bug somewhere.

    What happens if you run the attached conftest.c instead? It's the same as 
    before, except with an 'alarm (10)' call. As before, run it like this in 
your 
    development directory:

    rm -fr conftest3
    gcc conftest.c
    strace -o tr ./a.out

    and see how 'tr' ends if it hangs (which I hope it doesn't).
