* include/cygwin/version.h: Bump DLL minor version number to 5 due to all of the changes below. Redefine process structure to avoid a fixed size table. Redefine pinfo/_pinfo classes. Use these throughout. * dcrt0.cc (dll_crt0_1): Accomodate set_myself argument change. (__api_fatal): Accomodate _pinfo::record_death argument change. * exceptions.cc (really_exit): Ditto. (sig_handle_tty_stop): Use pinfo constructor to access process info. (events_init): Don't create pinfo_mutex since it is no longer required. * external.cc (fillout_pinfo): Use winpids class to iterate over all system pids. (cygwin_internal): lock_pinfo_for_update and unlock_pinfo are now noops. * fhandler_termios.cc (fhandler_termios::set_ctty): Use pinfo constructor to access process info. * fork.cc (fork): Reorganize to initialize child info after the child has started since that is when we know the child's winpid, which is necessary to allocate the pinfo shared memory. * mmap.cc (recreate_mmaps_after_fork): Change arg type to _pinfo. * pinfo.cc: Rename pinfo methods to _pinfo throughout. Eliminate pinfo_list stuff. (set_myself): Accept a pid argument now. Call pinfo initializer to initialize myself. Detect when this is an "execed" process and create an "indirect" pid block. (pinfo_init): Accomodate set_myself arg change. (procinfo): Remove. (pinfo::lock_pinfo): Remove. (pinfo::unlock_pinfo): Remove. (pinfo::init): New method. Allocates shared memory space for process pinfo structure. (pinfo::record_death): Don't call locking functions. (cygwin_winpid_to_pid): Simplify by using new pinfo constructor. (EnumProcessesW95): New function for iterating over processes on Windows 95. (winpids::winpids): New constructor for winpids class. Sets up a list of process ids. (enum_init): Initialize w95/wnt pid enumerators. * shared.cc (shared-info::initialize): Remove pid initialization. * shared.h: Move pinfo stuff into pinfo.h. (class shared_info): Remove pinfo_list element. * signal.cc (kill_worker): Use pinfo constructor to access process info. (kill_pgrp): Ditto. Use winpids methods to access list of processes. * sigproc.cc: Throughout, modify to use _pinfo where appropriate. (proc_exists (pid_t)): New function. Determines if a process exists based on the pid. (proc_exists (_pinfo *p): Use new proc_exists function above. (proc_subproc): Copy pinfo stuff around rather than _pinfo pointers. Try to be careful about releasing shared memory when we don't need it anymore. Remove pinfo locks. (remove_zombies): Remove pinfo memory when zombie is going away. * sigproc.h: Reflect _pinfo/pinfo changes in sigproc.cc. * spawn.cc (spawn_guts): Eliminate pinfo *child argument. Reorganize to only initialize child pinfo after process has been started and we know the windows pid. (_spawnve): Reflect spawn_guts changes. * syscalls.cc (setpgid): Use pinfo constructor to access process info. (getpgid): Ditto. (internal_getlogin): Use _pinfo. * winsup.h: Eliminate pinfo_mutex. Eliminate spawn_guts declaration since it is static now. Reflect set_myself argument change. * include/sys/cygwin.h: Add some PID_* enums to accomodate new pinfo stuff. * include/cygwin/version.h: Update minor version for cygdrive changes below.
