Ok, great! (For development, the git repository might be more practical, though.) > I m going through the Open issues.Can you suggest something to start with. One possibility: last summer I added the SA_SIGINFO option for the sigaction() function, however some of the fields of the siginfo_t structure are not filled in properly because the information is not currently available to the process which receives the signal [1,2]. The goal would be to modify the sig_post() RPC, which is used to transmit a signal, so that all the information needed to fill in the siginfo_t is transmitted alongside with it. You would need to modify the Hurd interface definitions (for sig_post), the GNU C library (to fill in the siginfo_t structure when a signal is received, and also to transmit the information when kill() is used to send a signal) and some of the Hurd translators which use sig_post as well. You'll also have to check the POSIX standard [3] to understand exactly what each field of siginfo_t should contain under what circumstances. [1] http://www.bddebian.com/~hurd-web/open_issues/sa_siginfo_sa_sigaction/ [2] http://www.bddebian.com/~hurd-web/user/jkoenig/java/ (look for "SA_SIGINFO") [3] http://pubs.opengroup.org/onlinepubs/9699919799/ It's not trivial but not horribly hard either, I can give you a hand, and I think it would be a great way to learn your way around the codebase. (But of course it's just a suggestion and if you find something you think is more appropriate feel free to ask us about it.) -- Jérémie Koenig <j...@jk.fr.eu.org> http://jk.fr.eu.org/
