[Openslp-devel] slptool hangs on AIX?

[Jim M. <jim...@wb...>]

Hi,
  Been testing the AIX build I have and the agent is working fine but 
when I invoke slptool it basically hangs. Stepping into the code we get 
to libslp_handle.c line 66

if (SLPAtomicInc(&s_OpenSLPHandleCount) == 1)

The SLPAtomicInc function does this on AIX:

return (intptr_t)fetch_and_add((atomic_p)pn, 1);

This is the cause of the hang, because fetch_and_add "[...] returns the 
original value of the variable" (from the man page), in this case '0'. 
When this happens the code enters a while loop

       while (!s_HandlesInitialized)
          sleep(0);

The only way I can work around this is to remove the "#define 
USE_AIX_ATOMICS" (line 137 of slp_atomics.c).

This code has been in OpenSLP for a long time (Aug 2006), so I am 
wondering if this is working for others? And if so, how?

Thank you
