(select_stuff::wait): Ditto. 2013-01-11 Corinna Vinschen * syscalls.cc (rename): Drop handling paths > 32757 chars, emit EINVAL instead, thus simplifying code allocating and filling pfri.

Remove unneeded call to lookup_reader(). * thread.h (pthread_rwlock::RWLOCK_READER::RWLOCK_READER): New constructor. (pthread_rwlock::add_reader): Reflect new functionality. 2013-01-03 Christopher Faylor * globals.cc (exit_states): Renumber so that ES_EXIT_STARTING is first, as intended. * sigproc.cc (wait_sig): Only stop accepting signals after exit_state > ES_EXIT_STARTING. 2013-01-03 Christopher Faylor * sigproc.cc (exit_thread): Set thread signal mask so that no signals are sent to an exiting thread. 2013-01-02 Christopher Faylor * sigproc.cc (no_signals_available): Remove exit_state test since signals are available in a limited fashion when exiting. (sig_dispatch_pending): Ditto. (sig_send): Ditto. (exit_thread): Rearrange to avoid an unnecessary DuplicateProcess when exiting. (wait_sig): Allow special signals when exiting. 2013-01-02 Christopher Faylor * DevNotes: Add entry cgf-000020, relating to previous checkin. 2013-01-02 Christopher Faylor * cygtls.h (_cygtls::signal_exit): Delete from class. * exception.h (cygwin_exception): New class.

Pass exception information to sig_send via new siginfo_t si_cyg field. (ctrl_c_handler): Wait for SIGHUP signal to be processed since it could cause a process exit and we don't want races with thread exit lock. (signal_exit): Move back here from sigproc.cc. Modify arguments and remove from sigpacket class. Decide when to dump core based on signal type. (sigpacket::process): Handle exiting signals in context of threads rather than in the signal thread.
