| | | | | | * ALL: Use new runtime.h. Change init_module() to probe_start() and don't do transport calls. Remove MODULE_LICENSE and cleanup_module().
* Fix accidently commented-out line.hunt2005-07-081-1/+1

* 2005-07-08 Martin Hunt <hunt@redhat.com>hunt2005-07-081-8/+20
| | | | | | * shellsnoop/shellsnoop.c (init_module): Call _stp_transport_close() if initialization fails. (cleanup_module): Call _stp_transport_cleanup().
* 2005-07-08 Martin Hunt <hunt@redhat.com>hunt2005-07-083-62/+88
| | | | | | | | | | | | | | | | | | * transport.c: Rename pid to _stp_pid. Rename t to _stp_tport. (_stp_cleanup_and_exit): New internal function. (stp_exit_helper): Call _stp_cleanup_and_exit(). (_stp_transport_cleanup): New function. (_stp_cmd_handler): Remove handler for STP_TRANSPORT_MODE. The transport now notifies the daemon of the transport. (_stp_transport_close): No longer calls _stp_exit_helper(). That is done by _stp_transport_cleanup(). (_stp_transport_open): When done, call _stp_handle_transport() to notify the daemon what our transport is. (_stp_transport_send): Put a retry limit on sends. * transport.h: Rename pid to _stp_pid. (_stp_transport_cleanup): Add prototype.

| | | | | | * print.c (_stp_print_flush): Rename "t" to "_stp_tport". * io.c (_stp_vlog): Ditto.

| | | | | | | | | | | | | | | | * librelay.c (sigchld): Signal handler to detect completion of module loading. (init_stp): Use fork/exec instead of system() so we can get async signal of module load success/failure. (cleanup_and_exit): New function. (sigproc): If module is not loaded, don't send message to it. (stp_main_loop): Call cleanup_and_exit() when STP_EXIT is received. Don't send a request for the transport mode. The module will send notification to the daemon when it is ready. * stpd.c (main): Don't print message until module is loaded.
