2005-01-26* pinfo.h (pinfo::init): Make third parameter non-optional and propagate changeChristopher Faylor
throughout. * pinfo.cc (set_myself): Pass INVALID_HANDLE_POINTER if h is NULL. (pinfo::init): Make third parameter non-optional. Eliminate use of PID_EXECED as an argument. Put setting of handle back inside loop but reorganize to try to open it only when necessary.

(getpriority): Ditto. (nice): Just call setpriority. * wincap.h (wincaps::has_extended_priority_class): New element. * wincap.cc: Implement above element throughout. * winsup.h: Add prototypes for winprio_to_nice and nice_to_winprio. * include/limits.h (NZERO): New define. * include/cygwin/types.h (id_t): New datatype. * include/cygwin/version.h: Bump API minor version. * include/sys/resource.h: Add PRIO_XXX defines and prototypes for getpriority and setpriority.
2005-01-17* pinfo.h (maybe_set_exit_code_from_windows): Renamed from set_exit_state.Christopher Faylor
* pinfo.cc (pinfo::exit): Use renamed function. (proc_waiter): Ditto. Make a copy of input argument to avoid problems when procs array is shuffled. Flag when copy is made so that remove_proc knows when it is safe to reshuffle. * sigproc.cc (proc_terminate): Don't flag process_state as PID_EXITED. (remove_proc): Wait for waiter to finish copying pinfo element before moving it (an actual wait should be an extremely rare event).
2005-01-16* init.cc (dll_entry): Remove unused extern.Christopher Faylor
* include/sys/cygwin.h: Remove PID_ZOMBIE. * pinfo.h: Rename EXITCODE_* defines. (pinfo::set_exit_state): Remove parameter. * pinfo.cc (set_exit_state): Remove parameter. Reverse sense of test so that exitcode is checked for having been set rather than not having been set. Set flag when exitcode has been established. Don't set PID_STATE here. (pinfo::init): Remove exitcode initialization. (pinfo::exit): Reflect change in EXITCODE_* naming. Set flag when exitcode has been established. Reflect change in arguments to set_process_state.

(_pinfo::set_exit_state): Define new function. (_pinfo::dup_proc_pipe): Close handle when there is no parent process around to care about the exit value. * dcrt0.cc (dll_crt0_0): Move subproc_ready synchronization later to make sure that myself is still mapped in parent. (do_exit): Reflect movement to pinfo::exit. (__api_fatal): Ditto. * exceptions.cc (signal_exit): Ditto. * errno.cc (errmap): Map PROC_NOT_FOUND. * init.cc (dll_entry): Release myself before exiting. * sigproc.cc (proc_can_be_signalled): Set errno appropriately.

(child_info::sync): Don't set exitcode here. Assume that will happen in proc_waiter, if necessary. * spawn.cc (spawn_guts): Delay "wait_for_myself" logic until later. Don't wait at all if the process has already exited. Reflect movement to pinfo::exit.

hProcess handle here since it is used to ensure that a new process isn't created with the old pid after the old pid exits. * spawn.cc (spawn_guts): Ditto. * pinfo.cc (proc_waiter): Don't send any signals if we've execed since this process doesn't officially exist. * pinfo.h (pinfo::pid_handle): Eliminate. Just use hProc. * sigproc.cc (sig_send): Don't send any signals if our sendsig doesn't exist. That's a sign that we are execing. (remove_proc): Eliminate pid_handle close.
