Linux event handling
I had a little chat with Andrew Morton on Monday. The topic was the event handling, async I/O, etc. All the same stuff I talked about in Ottawa at OLS this year (paper and slides on my web page). Unfortunately not much has happened since OLS. Lots of people said they would be willing and able to help but life intervened, I guess. I’m no kernel developer but perhaps I have to start taking this up (
udrepper: POSIX and C++
POSIX is basically a standard defining C interfaces. There are additional language bindings for Ada and Fortran but those are not closely related to the C specification. Ada has requirements stemming from the Ada language which specifies a lot that is not part of the C language (like the equivalent of threads). The Fortran language binding isn't really complete. Languages like Java won't ever get
MALLOC_PERTURB_
Seems like the number of people who know this feature is still almost zero. Well, RH developers know it and we have some who use it all the time on development machines. Basically, setting this environment variable causes the malloc functions in libc to return memory which has been wiped and clear memory when it is returned. Of course this does not affect calloc which always does clear the memory.

Cancellation and C++ Exceptions In NPTL thread cancellation is implemented using exceptions. This does not in general conflict with the mixed use of cancellation and exceptions in C++ programs. This works just fine. Some people, though, write code which doesn't behave as they expect. This is a short example: #include <cstdlib> #include <iostream> #include <pthread.h> static pthread_mutex_t m = PTH
