#include <stdlib.h>
* 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.

* dtable.cc (dtable::release): Check for socket. Change cnt_need_fixup_before accordingly. (dtable::dup2): Ditto. (dtable::fixup_before_fork): New method. (dtable::fixup_before_exec): Ditto. * dtable.h (class dtable): Add member `cnt_need_fixup_before'. Add definition for methods `dec_need_fixup_before', `inc_need_fixup_before', `need_fixup_before', `fixup_before_exec' and `fixup_before_fork'. * fhandler.h (class fhandler_base): Slight rearrangements. Add definitions for methods `fixup_before_fork_exec'. (class fhandler_socket): Eliminate superfluous constructor. Add member `prot_info_ptr'. Add destructor. Add definitions for methods `dup', `fixup_before_fork_exec', `fixup_after_fork' and `fixup_after_exec'. * fork.cc (fork_parent): Care for file types which need a fixup before fork. Start child in suspended state then. * net.cc: New global variable `ws2_32_handle' and `wsadata'. (fdsock): Check for Winsock version. Call `set_socket_inheritance' only if Winsock version < 2.0. Care for `need_fixup' count in fdtab. (cygwin_socket): Eliminate call to `set_socket_inheritance'. (cygwin_accept): Ditto. (cygwin_rcmd): Ditto. (cygwin_rresvport): Ditto. (cygwin_rexec): Ditto. (socketpair): Ditto. (fhandler_socket::fhandler_socket): Set `need_fork_fixup'. Allocate space for the WSAPROTOCOL_INFOA struct used in fixup. (fhandler_socket::~fhandler_socket): New destructor. (fhandler_socket::fixup_before_fork_exec): New method. (fhandler_socket::fixup_after_fork): Ditto. (fhandler_socket::dup): Ditto. (wsock_init): New static function. (LoadDLLinitfunc (wsock32)): Rearranged. (LoadDLLinitfunc (ws2_32)): New function. (dummy_autoload): Add autoload statemants for `WSADuplicateSocketA' and `WSASocketA'. * spawn.cc (spawn_guts): Care for file types which need a fixup before exec. Start child in suspended state then.
