RE: Race condition in list_consume()

It is a great ideea to first add it to bug tracking list.

 

The sum is not to call functions which imply synchronization from the signal
handler. 

Those are debug()/warning()/etc and log_reopen() which indeed are in the
application but in turn are calling gwlib/pthreads synchronization
functions.

 

Bearerbox handles signals by setting a flag when receiving the signal in
order to process it synchronously. Btw… shouldn’t it use atomic/interlocked
primitives when setting the flag?

the sum is

 

dont call debug(), warning(), info() etc while being in a signal handler.

Now this is not in gwlib but in the application.

 

My application had a signal handler out of the model of bearerbox but it
might be me who added info() there.

So we have to check how the *box signal handlers look like.

My pleasure :-)

 

Now this issue might happen in smsbox and wapbox because they call gwlib/log

from the signal handlers as opposed to the bearer box which properly handles

the signals.

 

Would anyone address this issue and commit the fix to CVS?

 

yep, I would, can you please sum up the issue.

 

I'd also be +1 for adding this first to the bug tracking system, so we have
a

track/log of the issue, since this is critical.
