Wed Dec 31 15:00:32 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * hinfo.cc (hinfo_vec::find_unused_handle): correct previous patch -- need to fix up vec[i].h pointers Wed Dec 31 14:13:22 1997 Ian Lance Taylor * regexp/Makefile.in (tooldir): New variable. (install): Install regexp.h. Tue Dec 30 19:52:46 1997 Ian Lance Taylor * net.cc (inet_netof): New function. (inet_makeaddr): New function. * cygwin.din: Export inet_netof and inet_makeaddr.

(chdir): Move here from syscalls.cc. Clear directory cache variables. * syscalls.cc (chdir): Remove; now in path.cc. * environ.cc (setenv): Add cast to avoid warning. * security.cc (get_file_attribute): Make file parameter a pointer to const char. (set_file_attribute): Likewise. * winsup.c (get_file_attribute): Update declaration. (set_file_attribute): Likewise. * path.cc (path_conv): Don't pass the root directory to symlink_check_one. Mon Dec 22 16:34:40 1997 Ian Lance Taylor * path.cc (realpath): Use path_conv to resolve symlinks. * path.cc (path_conv::path_conv): Rewrite completely to convert to win32 path first and then check for symlinks element by element. (symlink_check_one): New static function based on old symlink_check_worker, but without path conversion. (path_prefix_p): Move definition before all uses. (skip_n_slashes, symlink_expand, symlink_follow): Remove. (symlink_check_worker, symlink_check): Remove. (readlink): Rewrite to use new symlink_check_one. (unmixedcaseify, mixedcaseify): Comment out. * path.h (symlink_check, symlink_follow): Don't declare. * fhandler.cc (open): Don't pass O_NOSYMLINK to path_conv. Set errno from path_conv if it fails. * dirsearch.cc (opendir): Check errors from path_conv, and set errno appropriately. * times.cc (utimes): Likewise. * syscalls.cc (_unlink, _link, mkdir, rmdir, chdir): Likewise. (chmod, _rename): Likewise. (_stat_worker): Don't just pass nofollow to _open, but base whether to pass O_NOSYMLINK on whether nofollow is set. (lstat): Pass 1, not O_NOSYMLINK, to _stat_worker. * strerror.cc (strerror): Add ELOOP. Thu Dec 18 12:30:47 1997 Ian Lance Taylor * fhandler.h (class fhandler_base): Remove inline definitions of tcflush, tcsendbreak, tcdrain, tcflow, tcsetattr, tcgetattr, tcsetpgrp, and tcgetpgrp, so that we can set proper errno values. (class fhandler_tty): Add pgrp_ field, and virtual tcgetpgrp and tcsetpgrp functions. * fhandler.cc (fhandler_base::tcflush): New function. (fhandler_base::tcsendbreak): New function. (fhandler_base::tcdrain): New function. (fhandler_base::tcflow): New function. (fhandler_base::tcsetattr): New function. (fhandler_base::tcgetattr): New function. (fhandler_base::tcsetpgrp): New function. (fhandler_base::tcgetpgrp): New function. (fhandler_tty::fhandler_tty): Initialize pgrp_. * tty.cc (tcsetpgrp): Set errno correctly on failure. * include/sys/termios.h (CBAUD): Change to 037. (B57600, B115200): Change to values that can fit in a speed_t. * spawn.cc (spawn_guts): Set errno correctly if we can't find the executable. Mon Dec 15 16:40:07 1997 Geoffrey Noer patch from msnyder@cygnus.com (Michael Snyder): * heap.cc (_sbrk): handle situation where newalloc < incr Mon Dec 15 16:40:07 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): Allow Cygwin32 to terminate process even when in a blocking winsock call. * exceptions.cc (call_handler): call to WSACancelBlockingCall() removed. (sighandle): call WSACleanup() before exiting the process to cancel blocking winsock calls. * include/mywinsock.h: add proto for WSACleanup(). Mon Dec 15 16:40:07 1997 Geoffrey Noer * Makefile.in: compile .cc files with -fno-exceptions to decrease dll size and increase execution speed a little. Mon Dec 15 16:40:07 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * tty.cc (do_input): Detect CTRL-T as a special case when STRACE_CACHE is active. Dumps the strace cache to disk. * console.cc (fhandler_console::read): Detect CTRL-T as a special case when STRACE_CACHE is active. Dumps the strace cache to disk. Sat Dec 13 15:12:53 1997 Ian Lance Taylor * fork.cc: Include . (cygwin_fork_helper1): Call __malloc_copy after copying the stack and heap to the child. Thu Dec 11 15:14:40 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * sigproc.cc (proc_subproc): Remove over-enthusiastic test for process handling readiness or proc_wait will loop attempting to handle a dying subprocess when signal handlers are not ready. * fork.cc (cygwin_fork_helper1): Reorganize to ensure that a forked process is capable of receiving signals when fork() returns. Wed Dec 10 15:43:37 1997 Ian Lance Taylor * include/sys/termios.h (IXANY): Correct value. (PARMRK): Define again. Wed Dec 10 00:05:23 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * dcrt0.cc (dll_crt0_1): Move start time initialization to a more logical place (pinfo_init). (do_exit): Reorganize to attempt to solve races when a cygwin process occupies two windows pids (i.e., an execed process). * exceptions.cc (lock_cs): Fix erroneous WFSO logic. (sighandle): Use new method for determining if process was initiated via fork. (events_terminate): Do not close pinfo_mutex. Allow automatic close by ExitProcess to lengthen the time that the pinfo structure is locked, minimizing races between an exiting child and a potentially exiting parent. * hinfo.cc (hmap_init): Use new method for determining if process was initiated via fork. (hinfo_vec::de_linearize_fd_array): Fix a typo in a comment. * pinfo.cc (clearout): Remove this function. Handled in allocate_pid. (pinfo_init): Move start_time setting here from dll_crt0_1. Remove call to init_self in favor of adding three additional lines of code. (pinfo_list::operator []): Implement a very simple hashing scheme for pid lookup. (lpfu): New routine controlled by DEBUGGING conditional. When DEBUGGING is activated, lpfu returns more information about the state of a timed out pinfo_mutex. (pinfo_list::get_empty_pinfo): Remove function. Move functionality to allocate_pid. (allocate_pid): Implement a (very) simple hashing scheme for finding an available pid. Take advantage of reorganized pinfo structure to zero all pertinent fields with one memset. (pinfo::record_death_nolock): Don't bothering zeroing inconsequential stuff. (pinfo::record_death): Leave pinfo_mutex locked with the understanding that this function will be called just prior to exiting the process. This minimizes a race between a child which is exiting at nearly the same time as its parent. * sigproc.cc: Reformat function calls. (sigproc_init): Clear new PID_INITIALIZING flag to indicate that a (possibly execed) process is now capable of receiving signals. (sig_send): Be more defensive in determining if a signal can be sent to myself or suffer problems with execed processes. (sigproc_terminate): Wait for sig_proc to exit to ensure that all pending signals have been handled. Use new 'proc_terminate' function to terminate the subprocess handling thread. (allow_sig_dispatch): Don't bother blocking signals if signal handling isn't active in this process yet. (block_sig_dispatch): Don't bother blocking signals if signal handling isn't active in this process yet. (sig_proc): Use sig_loop_wait variable to control wait time for signal semaphores. Uncouples this wait from wait_subproc. Perform signal cleanup here on thread termination. (proc_exists): More accurate tests to determine if a process really exists. (proc_register): Remove this function in favor of a macro. (proc_subproc): More stringent test for being "ready" to process subprocesses. Add more common initialization to PROC_ADDCHILD. Remove PROC_EXIT in favor of a separate function. (proc_terminate): New function. Replaces PROC_EXIT functionality in proc_subproc. Terminates subproc handler thread. (stopped_or_terminated): use lock_pinfo_for_update when modifying child stopsig status or suffer a race. (wait_subproc): Save sig_proc thread handle away for synchronization when exiting. Set up 'i_am_alive' mutex inherited by childen. Child's inability to lock this mutex means that the parent is still alive and processing children. Use proc_loop_wait to control WFMO. Clean up events queue on thread exit. (zap_subproc): Clear out pinfo structure for a child. * sigproc.h: Remove PROC_EXIT constant. Remove obsolete proc_register declaration. (alive_parent): New macro to determine if a parent is still alive. * spawn.cc (spawn_guts): Fix a comment typo. Use proc_terminate to terminate all subprocess handling prior to an exec. Use new method for determining if this process was started via a fork. Attempt to clean up races between execed process, its parent, and the execed child. * winsup.h (pinfo): Add a new handle indicating that a parent is alive. This should be a foolproof way of determining if a parent has gone away so that a child will know whether to remove itself from the pinfo table. Reorganize the structure in such a way that items to be zeroed are grouped together at the beginning for more efficient zeroing in allocate_pid. Add a new PID_* constant. New lock_pinfo_for_update macro for use when debugging cygwin. Wed Dec 10 00:05:23 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): Change the way to inherit fd table on spawn/exec calls. Use STARTUPINFO structure to pass an fd table to a child process instead of shared memory area. This is undocumented, but is used by MSVC runtime. The desktop inheritance code added again, otherwise user32.dll will fail to initialize after sexec calls. * pinfo.cc (pinfo_init): delinearize fd array from STARTUPINFO structure instead of call to copy_shared_fd_table. * shared.cc (create_shared_fd_mapping_name): remove (create/copy_shared_fd_table): remove * spawn.cc (spawn_guts): use lp(cb)Reserved2 fields of STARTUPINFO to pass fd table to a child. Remove call to create_shared_fd_table. Inherit window station/desktop on sexec calls. * winsup.h: remove prototypes for create/copy_shared_fd_table. Fri Dec 5 18:57:42 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * kill.cc (main): Report error if kill() fails. Minor reformat. * ps.cc (main): Only use month/day in start time when starting time is > 24 hours in the past, not when it occurs yesterday. Fri Dec 5 15:54:41 1997 Geoffrey Noer * fcntl.cc (_fcntl): reformat * fhandler.cc (fhandler_tty::open): new, need special open for ttys. In addition to calling fhandler_base::open, check flags to handle blocking vs. non-blocking I/O. Should initialize tty to standard state (9600 bits/sec - 8 - 1 with no flow control) but this code needs more work still. Ifdef out for now. (fhandler_tty::tcsendbreak): new (fhandler_tty::tcdrain): new (fhandler_tty::tcflow): new (fhandler_tty::tcsetattr): add support for action arg. Use a DCB struct to hold the values we will set. First call GetCommState to get the current state, then reassign values based on the contents of the termios struct. Handle the case where t->c_ospeed is set to B0, otherwise set state.BaudRate. Set all the other DCB struct values appropriately, based on the contents of the termios struct. (fhandler_tty::tcgetattr): do the inverse of tcsetattr. Call GetCommState to get the current state and use this to set the appropriate termios struct values. * termios.cc: reformat (tcsendbreak): implement -- add duration arg, call fhandler tcsendbreak as appropriate (tcdrain): implement -- call fhandler tcdrain as appropriate (tcflow): implement -- call fhandler tcflow as appropriate * fhandler.h: add new tc* protos * include/sys/termios.h: correct values of iflag bits, define CRTSXOFF and CRTSCTS, CBAUD, B57600 and B115200. Add protos for tc* functions. Wed Nov 26 17:06:17 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * spawn.cc (perhaps_suffix): resolve symlinks to .exes. Mon Nov 24 17:10:49 1997 Geoffrey Noer * cygwin.din: remove crypt * syscalls.cc (crypt): remove crypt stub Sun Nov 23 17:34:42 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * spawn.cc (spawn_guts): save the path of the script itself, use the saved path while building the command line to execute. Thu Nov 20 22:58:23 1997 Geoffrey Noer * stubs.cc: delete file, move unimplemented stubs to the files in which they would normally belong. * grp.cc (setgrent): implement (was in stubs.cc) * syscalls.cc: move regfree, mknod, setgid, set(e)uid, sync, crypt, and PPC __chkstk/_alloca/dll_entry stubs here from stubs.cc (sync): just return zero for now instead of -1 (crypt): return -1 instead of 0 Thu Nov 20 22:41:57 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * spawn.cc (spawn_guts): A premature close of the spawned filehandle was possible when reparenting an exited process. Fix this. * dcrt0.cc (do_exit): Only do minimal cleanup if "pid focus" has moved to another windows process or the other process will become confused. patch from sos@prospect.com.ru (Sergey Okhapkin): * sigproc.cc (getsem): set errno to EPERM if existing semaphore cannot be opened. (wait_subproc): allow access to signal semaphores to process's owner only except for SIGCHLD (needed for SIGCHLD delivery after sexecXX calls). Thu Nov 20 00:52:58 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * syscalls.cc (hash_path_name): Ignore trailing backslash when calculating pathname hash. * hinfo.cc (hinfo_vec::de_linearize_fd_array): Set use_tty if /dev/ttyn is detected in the shared_fd_table. Before this change, executing "set CYGWIN_TTY=1", "bash", "unset CYGWIN_TTY", "/bin/pwd" would result in pwd printing nothing because the de_linearize code would use the wrong fhandler_xxx when reading from the buffer inherited from the parent process. * cygwin.din: Add new ctermid function for export. * syscalls.cc (ctermid): New function * exceptions.cc (call_handler): If called during a P_OVERLAY spawn, merely set appropriate flags and return. The spawn code will then clean up and exit. * sigproc.cc (proc_exists): Reorganize to better detect defunct processes. Don't clean up pinfo if process has a parent since the parent should clean up eventually. * spawn.cc: New global exec_exit. Set by signal handler to value which should be used on exit from aborted spawn. (spawn_guts): Try harder to let the child terminate (if it is going to) before exiting on a signal. Remove obsolete code. patch from sos@prospect.com.ru (Sergey Okhapkin): * exec.cc (file_exists): Removed * spawn.cc (spawn_guts): call perhaps_suffix to convert filename to win32 form and to check file existance; prog variable removed, all references changed to real_path variable. Do not inherit parent's window station/desktop on sexecXX calls. They are no longer needed with the new signal handling. (_spawnve): extra file existance check removed * winsup.h: file_exists prototype removed Wed Nov 19 16:23:47 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * cygwin.din: add missing exports for random -- initstate and setstate (accessed by gawk among others?) Tue Nov 18 22:27:10 1997 Geoffrey Noer * Makefile.in: Add spaces after colons in rules for make Mon Nov 17 22:35:25 1997 Geoffrey Noer patch from proven@cygnus.com (Chris Provenzano): * Makefile.in: set SHELL = @SHELL@, set VPATH to only @srcdir@. Remove mingw from directories to build for now, adapt rules for building sysdef files without fancy VPATH * configure: regenerate * config/i386/makefrag: add rules to build setjmp/longjmp * regexp/Makefile.in: set SHELL = @SHELL@ * regexp/configure: regenerate * utils/Makefile.in: set SHELL = @SHELL@ * utils/configure: regenerate Mon Nov 17 18:36:50 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * fhandler.cc (fhandler_disk_file::open): calls to symlink_XXX replaced with path_conv class calls. * path.cc (path_conv::path_conv): comments added, O_NOSYMLINK case added. * path.h (class path_conv): symlink_p, exec_p - new class members. * spawn.cc (spawn_guts): call path_conv instead of symlink_follow. Sun Nov 16 15:54:27 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * dcrt0.cc (do_exit): Use new pinfo element in debug statement. * pinfo.cc (pinfo_init): Eliminate use of "PID" environment variable in favor of scanning the process table for a SpawnedProcessId field matching current windows process id. Should speed up spawned process startup slightly. Delay setting of dwProcessId until process is capable of processing signals since this field is used to build signal semaphores. * signal.cc (kill_worker): Perform a `proc_exists' on the pid in question if signal == 0. This will verify that the process actually exists and was not abnormally terminated. * sigproc.cc (sigproc_init): Initialize dwProcessId field after signal processing has been initialized. (sigproc_terminate): Remove events[0] close. (getsem): Use GetCurrentProcessId to find the windows pid since this dwProcessId field is not yet set up. Use proc_exists to determine if error should be printed on OpenSemaphore error. (proc_exists): New function. Makes more exhaustive test of process existence. Determines if process died without going through normal shutdown. (wait_subproc): Close wakeup event only on thread exit. * spawn.cc: Remove pExeced. Use new field in pinfo. (spawn_guts): Initialize dwSpawnedProcessId field. * utils/ps.cc (main): Perform a kill(pid, 0) on any pids that appear to be active. This will clear out pids that have died abnormally. 'ps -f' bypasses this. * winsup.h (class pinfo): Add dwSpawnedProcessId field. Sun Nov 16 15:54:27 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * pinfo.cc ((pinfo_init): use dwProcessId for execed/spawned check, set subproc_ready event only if the process is exec'ed. * spawn.cc (spawn_guts): initialize hProcess and dwProcessId fields of pinfo on exec, keep progname field on spawn. Sun Nov 16 15:54:27 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * dcrt0.cc: remove commented out code * spawn.cc: fix misapplied patch problem Sun Nov 16 15:54:27 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * fhandler.cc (fhandler_dev_null::open): Open Windows 'nul' device rather than "faking" a real open. (fhandler_dev_null::close): delete. (fhandler_dev_null::fstat): delete. (fhandler_dev_null::ioctl): delete. (fhandler_dev_null::read): delete. (fhandler_dev_null::write): delete. (fhandler_dev_null::lseek): delete. (fhandler_dev_null::dup): delete. * fhandler.h (class fhandler_base): delete above methods from class. * hinfo.cc (hinfo_vec::build_fhandler): Use new fhandler_dev_null class which opens 'nul' device. Treat /dev/null similarly to other Windows devices. This allows redirection of /dev/null to non-cygwin processes. Sun Nov 16 15:54:27 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * dcrt0.cc (do_exit): Use EXIT_* flags to determine how exit should proceed. Honor new EXIT_NOCLOSEALL to avoid close_all_files. * exceptions.cc (__cygwin32_exception_handler): Use new EXIT_SIGNAL define to indicate exiting due to signal. * signal.cc (sigprocmask): Slightly more defensive check against being called prior to complete cygwin setup. (_raise): Defensive check to guard against being called prior to complete cygwin setup. * sigproc.cc (stopped_or_terminated): Use new EXIT_SIGNAL define to detect exiting due to signal. * sigproc.h: Define flags to be used during exit process as EXIT_*. * spawn.cc (spawn_guts): Use EXIT_* constants to control how do_exit proceeds after _P_OVERLAY. Sun Nov 16 15:54:27 1997 Geoffrey Noer * sysconf.cc (sysconf): return 1048576 for ARG_MAX until we figure out the right value (_POSIX_ARG_MAX is only 4K which is too small). Sun Nov 16 15:54:27 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * dcrt0.cc (dll_crt0_1): call winsock_init if neccesary. * fhandler.cc ((fhandler_socket::fhandler_socket): moved to net.cc * fhandler.h (class fhandler_socket): destructor prototype added. * fork.cc (cygwin_fork_helper1): set PID_SOCKETS_USED in the child's pinfo if parent has open socket descriptors; call winsock_init in child code if necessary. * net.cc: static variable winsock_init_p removed; number_of_sockets is new global variable containing number of opened sockets. (winsock_init): made global, save "winsock inited" flag in process state field. (cygwin32_winsock calls): condition for winsock initialisation changed (fhandler_socket::fhandler_socket): new, moved from fhandler.cc; increment number_of_sockets on constructor call. (fhandler_socket::~fhandler_socket): new. Decrement number_of_sockets on destructor call, check for negative value. (fhandler_socket::ioctl): check for winsock initialisation added. * spawn.cc (spawn_guts): handle PID_SOCKETS_USED in child's pinfo. * winsup.h: PID_SOCKETS_USED - new enum value; number_of_sockets and winsock_init() prototypes added. Wed Nov 12 23:02:34 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * exceptions.cc: Substitute do_exit for _exit as appropriate. do_exit allows full 32 bits of exit value. The upper 16 bits are used for special cygwin operations. * winsup.h: Change definition of do_exit to allow calling from signal handler. * dcrt0.cc (do_exit): Change to allow calling from signal handler in place of _exit. This is necessary to ensure that only cygwin internal applications can exit with the upper order 16 bits set to non-zero. Wed Nov 12 23:02:34 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * dcrt0.cc (do_exit): New function. Subsumes functionality of _exit but takes a DWORD argument. Changed to avoid some shutdown activities when called with REPARENTING bit set in argument. Also explicitly kills any executing non-cygwin subprocess from a spawn(P_OVERLAY)... (_exit): Use do_exit for exiting. Ensure that only low order 1 bits of status are used or confusion will result if exiting with some higher order bits set. * exceptions.cc (set_process_mask): Reflect new method for sig_send to send signals to self. (handle_sigsuspend): Reflect new method for sig_send to send signals to self. * fork.cc: A handle name was changed in the pinfo structure to be more reflective of its use. Change forkee_stopped to subproc_ready everywhere. * pinfo.cc (pinfo::clearout): Change forkee_stopped to subproc_ready. (pinfo_init): Use PID_EXECED flag to determine if this process has been execed. If so, signal the remaining stub in the process which invoked us so that the stub can terminate and let us take over as this pid. * sigproc.cc (sig_send): Change method for determining if sending signals to myself. A NULL pointer means communicate with my signal handler. This is necessary to allow communication with our own signal processors after reparenting an execed process. Also, add an additional test to detect if a process goes away in the middle of attempting to send it a signal. (allow_sig_dispatch): Reflect new method for sig_send to send signals to self. (getsem): Use dwProcessId in names for signal semaphores. Allows communicating with both parts of a process that is temporarily "split in two" while execing. (sig_proc): Avoid printing an error if WAIT_FAILED and exiting anyway. Process requests even if loop_wait == 0. (proc_subproc): Defensive check for manipulating processes prior to initialization or after terminating sigproc. Use different check for subprocesses that have been reparented. Hopefully this will eliminate WFSO, error 6 problems. (wait_subproc): Only exit when loop_wait == 0 and not dealing with a process. * spawn.cc: Set up two global variables, used on exit when execing a non-cygwin process: hExeced - handle of non-cygwin process which is being waited for by a stub, pExeced - windows pid of the process. (spawn_guts): Reorganize to always (temporarily) wait for the new process when P_OVERLAY. If a cygwin process is invoked, then the wait will return when an event is signalled and the new process will be "reparented" in the ppid. If a non-cygwin process is invoked, wait until the process exits or a signal is received which terminates the process. In this case, the do_exit function will terminate the non-cygwin process. * winsup.h: Rename forkee_stopped to subproc_ready since this event now has a dual role which is better defined by this new name. Add a new flag (PID_EXECED) for process_state. Define a new function `do_exit' which operates similarly to _exit but takes > 16 quantities with the high order bit signifying different exit actions. Mon Nov 10 17:11:08 1997 Geoffrey Noer * include/utime.h: remove (moved to newlib/libc/sys/cygwin32/sys) so as not to conflict with the one in newlib/libc/include. Mon Nov 10 15:11:42 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * exceptions.cc (__cygwin32_exception_handler): exit with "core dumped" exit code after writing "core" file. Mon Nov 10 15:11:42 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * console.cc: Add convenience macros and structures for handling scrolling. (fhandler_console::fillin_info): New function to fill in the `info' struct. (fhandler_console::scroll_screen): Change to scroll only the visible portion of the screen. Honor scroll regions more stringently. (fhandler_console::open): Use new fillin_info function. (fhandler_console::ioctl): Use new fillin_info function which automatically calculates screen size. (fhandler_console::clear_screen): Use new fillin_info function. Only clear visible portion of screen. (fhandler_console::cursor_set): Add a flag to indicate whether cursor positioning is absolute within buffer or is screen relative. Use new fillin_info function to get screen information. (fhandler_console::cursor_rel): Use new fillin_info function. Change for new cursor_set parameter. (fhandler_console::cursor_get): Use new fillin_info function. (fhandler_console::char_command): Use new fillin_info function where appropriate. Change for new cursor set parameter where appropriate. Scroll only visible portion of screen when required. * fhandler.h (class fhandler_console): Add fillin_info, change cursor_set to reflect additional argument. Mon Nov 10 15:11:42 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * dcrt0.cc (dll_crt0_1): Register process start time. * fork.cc (cygwin_fork_helper1): Register process start time. * utils/ps.cc (main): Report process start time. (start_time): New function to format time similarly to UNIX ps. A time from today shows as HH:MM, times from previous days just show the month and day. * winsup.h (class pinfo): Add start_time field. Mon Nov 10 11:54:27 1997 Ian Lance Taylor * include/Windows32/Defines.h (TIME_ZONE_ID_INVALID): Define. * times.cc (gettimeofday): The error return from GetTimeZoneInformation is TIME_ZONE_ID_INVALID, not TIME_ZONE_ID_UNKNOWN. Sun Nov 9 17:08:30 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * Makefile.in: add ../libiberty/strsignal.o * cygwin.din: add exports for strsignal, strtosigno * utils/kill.cc: changes to allow accepting signal name as argument Sun Nov 9 17:08:30 1997 Geoffrey Noer * include/limits.h: define PATH_MAX here instead of include/sys/param.h, define _POSIX_NGROUPS_MAX as 0 not 1 (system invariant value, not implementation-specific) * include/sys/param.h: remove PATH_MAX, change NOFILE from 64 to 8192, delete PATHSIZE, remove safety wrapper around MAXHOSTNAMELEN, add comments * sysconf.cc (sysconf): return NGROUPS_MAX not zero, return _POSIX_SAVED_IDS not zero. Return _POSIX_CHILD_MAX not 4096. Return _POSIX_CHILD_MAX, not 8. patch from sos@prospect.com.ru (Sergey Okhapkin): * winsup.h: add proto for setdtablesize, define NOFILE_INIT and NOFILE_INCR * hinfo.cc (hmap_init, hinfo_vec::find_unused_handle): change to support virtually unlimited numbers of fds. Remove setdtablesize proto * syscalls.cc: initialize dtable_size to NOFILE_INIT instead of NOFILE Thu Nov 6 13:14:09 1997 Geoffrey Noer * exceptions.cc (__cygwin32_exception_handler): don't print "In cygwin32_except_handler" for exceptions Cygwin32 isn't going to handle. Print "(progname PID) Exception: " to console. Redirect all detailed information including the stack trace to .core. This should reduce confusion about what's causing the exception (a lot of people would see "In cygwin32..." and think the problem was in Cygwin32 when most of the time it was in some other program). * syscalls.cc: add fixme * times.cc: add fixme Wed Nov 5 19:23:10 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * Makefile.in: force .c.os and .cc.os to be built in same directories as source Wed Nov 5 19:23:10 1997 Geoffrey Noer * drct0.cc (dll_crt0_1): stop initializing winsock on process startup since that slows down startup time of all processes, even ones that don't end up making Winsock calls. * fork.cc (cygwin_fork_helper1): don't need to call uinfo_init or socket_checkinit after fork -- the appropriate functions will do the necessary initialization if they are ever called. * net.cc: init winsock_init_p to zero and make it static (all exported functions): call winsock_init before making any WinSock calls since this no longer happens in dcrt0.cc startup code. Only do this if !winsock_init_p. (winsock_init): checkinit renamed. Now just inits winsock without checking whether it has been already initialized. Make it static. * uinfo.cc (uinfo_init): after we call getpwnam, we know the passwd file has been read in so don't check initialization of it. However, we do need to read_etc_group() if group_in_memory isn't set. * passwd.cc: rename global i variable to pw_pos, rename passwd_in_memory to passwd_in_memory_p to match net.cc scheme. Add comments. (read_etc_passwd): make static (various): make sure to read_etc_passwd() if passwd_in_memory isn't set * grp.cc: add comments, rename idx global to grp_pos, rename group_in_memory to group_in_memory_p to match net.cc scheme, group_in_memory_p no longer static (needs to be accessed by uinfo_init) * winsup.h: remove proto for socket_checkinit since that's renamed and static within net.cc Tue Nov 4 01:02:20 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * signal.cc (sigprocmask): Newer versions of gcc will call sigprocmask when a builtin constructor is activated. If this happens prior to the setup of u->self, then a NULL dereference will occur. Guard against this. Mon Nov 3 17:00:45 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * hinfo.cc (hinfo_vec::build_fhandler): Open a console for /dev/tty when !use_tty. Thu Oct 30 10:28:15 1997 Tom Tromey * include/mapi.h: New file. * sysdef/i386/mapi32.def (MAPISendMail@20): New export. Thu Oct 30 15:08:13 1997 Geoffrey Noer * times.cc: add comments listing standards funcs are defined in (dump_filetime): remove unused local func * net.cc (fail): remove local func, replace one reference with equivalent debug_printf, add standards comments, reformat a little (fhandler_socket::close): simplify handling of res (fhandler_socket::fstat): set ENOSYS (unimplemented) * stubs.cc: set ENOSYS in unimplemented funcs * uname.cc: add standards comment * ntea.cc: reformat Wed Oct 29 22:43:57 1997 Geoffrey Noer * times.cc (settimeofday): set ENOSYS instead of EPERM since ENOSYS maps to "Function not implemented" which is the case here. * syscalls.cc (seterrno): on failure, set EACCES instead of EPERM which is better for the unknown error case Fri Oct 24 01:24:07 1997 Geoffrey Noer patch from green@cygnus.com (Anthony Green): * dcrt0.cc: new host_dependent_constants object with a global instance of it which allows constants that are different in Win 95 and NT to be saved here instead of having forks in the code and having to check the OS type each time. Add two constants for fhandler, one for sharing attributes and one for upper word value for locking files. (dll_crt0_1): call host_dependent init function * fhandler.cc (fhandler_base::open): use above object for setting shared attributes (fhandler_disk_file::lock): get upper word for locking from host_dependent_constants * winsup.h: define host_dependent_constants class and add extern for global instance of it Wed Oct 22 02:27:53 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * cygwin.din: Export getenv, putenv, setenv and unsetenv instead of cygwin32_ wrappers * dcrt0.cc: External variable environ removed (dll_crt0_1): strip executable's path on console title if environment variable CYGWIN_TITLE set to "strip", references to environ removed. * environ.cc: New file. Code derived from newlib sources. * exec.cc: include stdlib.h (execl, execv): new (derived from newlib sources). (sexecve): reference to environ removed. (sexecvpe): call getenv instead of cygwin32_getenv. * grp.cc: new static variable group_in_memory (read_etc_group): skip blank lines (getgrgid, getgrnam, getgrent): call read_etc_group when necessary. * misc.cc (cygwin32_getenv/putenv/setenv/unsetenv): remove wrappers. * passwd.cc: new static variable passwd_in_memory (read_etc_passwd): skip blank lines (search_for, getpwent): call read_etc_passwd when necessary. (setpwent): fixed incorrect initialization of i var. * pinfo.cc (pinfo_init): initialize uid with illegal value to force read of /etc/passwd and /etc/group. * spawn.cc: call getenv instead cygwin32_getenv (spawn_guts): force read of /etc/passwd and /etc/group on sexec calls. * uinfo.cc (uinfo_init): read /etc/passwd and /etc/group only if uid is undefined. * winsup.h: remove protos for environ, cygwin32_getenv, cygwin32_putenv Wed Oct 22 02:08:54 1997 Geoffrey Noer * utils/aclocal.m4: new file. Define autoconf macros for determining whether we're compiling for the cygwin32 environment or not and determine the executable suffix * utils/configure.in: call AM_CYGWIN32 and AM_EXEEXT * utils/configure: regenerate * utils/Makefile.in: add $(exeext) after executable names so programs will be built with the .exe suffix Wed Oct 22 00:50:27 1997 Geoffrey Noer Now that it is possible to use gdb using a stable cygwin.dll to debug a program using a newer, potentially buggy cygwin.dll, the strace mechanism will probably end up being used more and more for debugging timing/race-condition bugs that aren't easily exposed in a gdb session. The following changes make the strace facility better for debugging timing issues by storing the last few commands in a buffer instead of writing to disk each function call. patch from cgf@bbc.com (Chris Faylor): * dcrt0.cc (dll_crt0_1): Change to strace_init call to take an argument (for planned future registry changes). (_exit): Call strace_dump when appropriate. Add a debugging printf. * include/sys/strace.h: Add _STRACE_CACHE, _STRACE_EXITDUMP, strace_dump (). * strace.c (strace_init): Allow hexadecimal, octal setting of strace flags in environment variable. Handle new cache option. (strace_printf): Display number of seconds from last message. Handle _STRACE_CACHE. (strace_dump): New function. Dump cached messages to disk. Wed Oct 22 00:08:40 1997 Geoffrey Noer * cygwin.din: export socket calls without cygwin32_ prefix * net.cc: remove unused herror function in favor of cygwin32_herror which is exported as herror * include/netdb.h: we are now exporting the socket calls without the cygwin32_ prefix so we don't need the nasty remapping in header files * include/arpa/inet.h: ditto * include/sys/socket.h: ditto * select.cc (select): make extern C Tue Oct 21 22:52:29 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * sigproc.cc (sigproc_terminate): Fix flawed attempt to signal any processes waiting for signal notification success when the process receiving the signal is terminating. (wait_subproc): Report on errors when opening the sync_proc_subproc mutex. Move initialization of events[0] "wakeup" signal prior to wait_subproc_inited or risk a (miniscule) chance for a reference to a NULL handle. * strace.cc (ta[]): Change WM_ASYNCIO entry to reflect previous changes to WM_ASYNCIO constant. Tue Oct 21 14:30:14 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * sigproc.cc (proc_subproc): fix minor error output problem Mon Oct 20 20:19:02 1997 Geoffrey Noer * Makefile.in: change DLL_NAME to cygwin97r2.dll Mon Oct 20 20:16:47 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * window.cc (alarm): When there is a previous alarm() request with less than one second remaining, then the return from a call to alarm() is supposed to return 1. Mon Oct 20 20:16:47 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * Makefile.in: Add sigproc.o target. Add sigproc.h dependency where appropriate.

Add missing return value to debug printf * syscalls.h: ftruncate length is an off_t, add proto for truncate patch from cgf@bbc.com (Chris Faylor): * console.cc (fhandler_console::write): Recognize '@' as a valid character to follow a '\e[' sequence or get 'Bad escape' errors. Wed Oct 15 18:44:25 1997 Geoffrey Noer * cygwin.din: restore __main as an export Mon Oct 13 18:41:09 1997 Geoffrey Noer * cygwin.din: revert renaming of __assert since that's actually what it's supposed to be called * assert.cc: ditto Fri Oct 10 19:25:49 1997 Tom Tromey * include/Windows32/Base.h: Moved typedefs of CHAR, SHORT, etc, before all other uses in file. Fri Oct 10 17:50:12 1997 Ian Lance Taylor * include/Windows32/Base.h: Only typedef CHAR, SHORT, and LONG if VOID is not defined Thu Oct 9 00:46:40 1997 Geoffrey Noer * cygwin.din: remove all libgcc.a exports. They don't belong here since libgcc.a doesn't really relate to the purpose of cygwin.dll, and (to make things worse) the contents change over time. * assert.cc: rename __assert to __cygwin32_assert * exceptions.cc: rename __stack_trace to __cygwin32_stack_trace, __cygwin_except_handler to __cygwin32_except_handler * version.h: increment major and minor numbers Tue Oct 7 12:52:25 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * dcrt0.cc (_exit): under Win 95, don't send SIGCHLD unless special env variable is set. This works around a problem where exiting a process can hang under Win 95. Mon Oct 6 23:41:34 1997 Geoffrey Noer * regexp: new directory containing free regexp code by Henry Spencer. Taken from the most recent release of NetBSD. Write configure.in and Makefile.in, based on files from winsup/utils. * Makefile.in: build regexp directory and include objs in cygwin.dll. * stubs.cc: remove all reg* stubs except for regfree which isn't provided by above code.

Change critical section to mutex since there are supposedly multi-processor problems with critical sections under NT. Use "lock_cs" and "unlock_cs" macros to lock/unlock critical regions. (init_exceptions): Change critical section initialization to mutex initialization. (set_process_mask): Use locking macros to control access to sig_mask. (ctrl_c_handler): Use lock_cs/unlock_cs to control access. (events_init): Use standard cygname function to create names for shareable objects. (events_init): Close cs mutex. * fork.cc: Use event flags which are specific to the child being forked. This prevents one process from prematurely activating another. It also makes fork slightly more thread-safe. (fork_init): Remove event initialization. (fork_terminate): Remove function. (cygwin_fork_helper1): Initialize events on a per-fork basis. Events are inherited in child's pinfo structure. Remove child->hThread initialization as it not needed. Use pi.hThread where child->hThread is used. Work around Windows 95 bug where a WaitForSingleObjects will sometimes return ERROR_INVALID_HANDLE when it is resumed after a suspend. * pinfo.cc: Remove references to hThread field whereever it occurs. * strace.cc: Use standard cygname function to create name for strace_mutex. Prevents confusion between different .dll versions. * wait.cc (wait_found): Remove reference to hThread. * winsup.h (class pinfo): Remove reference to hThread. Add per-process fork control event handles. * include/limits.h: Increase NGROUPS_MAX from 0 to 1 to reflect recent change to getgroups. Mon Oct 6 11:06:22 1997 Geoffrey Noer Oops. ../libio refers to objdir and is not the same as $(srcdir)/../libio. Thu Oct 2 23:12:19 1997 Geoffrey Noer Revert patches to sources applied after Sept 16. Removed relevant portions of ChangeLog entries. Some of those changes may reappear later (removing the entries makes this log easier to understand). Thu Oct 2 15:34:03 1997 Geoffrey Noer * Makefile.in: remove hardcoding of SHELL to /bin/sh, remove ../libio from INCLUDES since $(srcdir)/../libio is already included. * glob/Makefile.in: remove hardcoding of SHELL to /bin/sh Mon Sep 29 14:06:24 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * cygwin.din: add exports for rcmd, rresvport, rexec * net.cc (cygwin32_rcmd): new (cygwin32_rresvport): new (cygwin32_rexec): new * include/mywinsock.h: add protos for Winsock calls associated with functions called by the above. Mon Sep 29 13:26:24 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * grp.cc (getgrent): Change overlooked comment to reflect new behavior. Thu Sep 25 18:35:49 1997 Geoffrey Noer * Makefile.in: remove debugdll defs since the shared memory overlap problem is solved by the timestamp addition of Sept 23 * version.h: rework explanations of version numbers Thu Sep 25 16:21:49 1997 Geoffrey Noer * spawn.cc: add missing cast to debug printf Thu Sep 25 16:14:17 1997 Ian Lance Taylor * path.cc (conv_to_win32_path): Call backslashify on a win32 path. Tue Sep 23 17:58:17 1997 Geoffrey Noer Fixes for things that were causing compile-time warnings: * exec.cc (_execve): add missing const to args to match def of execve in newlib which this calls. (sexecve): add missing const to def (sexeclpe): don't need to cast argv in sexecvpe call (sexecvpe): add missing const to def * winsup.h: correct _execve proto, add protos for login/logout * syscalls.h: correct sexecve, sexecvpe protos * include/Windows32/Base.h: NULL should be defined differently for C++ * init.cc: respacing Tue Sep 23 17:05:50 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * dcrt0.cc (dll_crt0_1): don't use alloca for allocating storage for environment blocks because setenv() uses realloc! Tue Sep 23 17:05:50 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * Makefile.in (LD_STUFF): Add datestamp.o after DLL_OFILES. (datestamp.o): New target. datestamp.c is generated whenever .o files change. It creates a file containing a "date stamp" which is used by the function "cygname" to create named shared memory, events, mutexes, and semaphores used by cygwin.dll. The unique datestamp allows multiple loading of different cygwin.dll's even when they have incompatible use of shared memory areas. * init.cc (dll_entry): Create the name string used by cygname from the name of the invoking .dll + the datestamp of the .dll from the auto-generated datestamp.c * misc.cc (cygname): New function. Creates a standard Cygnus shared resource name given a prefix, a name (e.g., pinfo_mutex), and a numeric suffix (e.g., a pid). Replaces custom code in several files. Uses cygwin_dlldate from datestamp.c to construct names that are unique for a given cygwin load. * shared.cc (open_shared_file_map): Use standard cygname function to create names for sharable objects. Use static handle 'h' so that it can be closed later by shared_terminate. (shared_terminate): Guard against calling CloseHandle with a NULL handle. (create_shared_fd_mapping_name): Use cygname function to generate the name for the "fd_map". Tue Sep 16 23:34:36 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * fcntl.cc (_fcntl): correct errno value (EBADF instead of EBADFD). Tue Sep 16 17:22:28 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * include/Windows32/Defines.h: add missing defines needed for NTEA usage. * ntea.cc: remove them from here * syscalls.cc (_link): call CreateFile with FILE_WRITE_ATTRIBUTES flag instead of GENERIC_WRITE Tue Sep 16 17:22:28 1997 Geoffrey Noer patch from cgf@bbc.com (Chris Faylor): * pinfo.cc (pinfo_init): Fix a NULL pointer dereference when PID environment variable contains garbage. Thu Sep 11 16:51:40 1997 Geoffrey Noer * syscalls.cc (ftruncate): read file pointer location at beginning of function and restore it at the end Thu Sep 11 15:35:10 1997 Ian Lance Taylor * path.cc (backslashify): Don't turn a single trailing slash into a double trailing slash. Wed Sep 10 11:40:55 1997 Ian Lance Taylor * include/Windows32/Structures.h: Add PACKED to PRINTDLG. * include/Windows32/Functions.h: Add STDCALL to a few function declarations. Tue Sep 9 02:12:18 1997 Geoffrey Noer patch from sos@prospect.com.ru (Sergey Okhapkin): * syscalls.cc (_link): Implement hard links under NT with NTFS using the backup API. Default to copying the file (what we did before).

(spawn_guts): Sort the environment before passing it to CreateProcess. * exceptions.cc (exit_already): New file static variable. (__cygwin_exception_handler): If exit_already is set, just return. If we get an exception we don't recognize, let the next exception handler handle it. Just ignore the INVALID_HANDLE exception. (really_exit): Remove file static exit_already variable; use the global one. (events_terminate): Set exit_already. * include/Windows32/Defines.h (EXCEPTION_INVALID_HANDLE): Define. (STATUS_INVALID_HANDLE): Define. * include/Windows32/Functions.h: Declare some shell functions.

(tty_init): do not call attach_tty() in a exec'ed process (attach_tty): correct return value if !use_tty. (tty::init): initialize pgid and hwnd fields. (tty_list::terminate): clearout tty on master exit. (tty_list::allocate_tty): fixed a bug in a tty allocation.

(dll_crt0_1): call events_init() on application startup, set use_tty to FALSE if CYGWIN_NOTTY environment variable is defined, do not change console title if CYGWIN_NOTITLE environment variable set, call tty_init(). (_exit): call tty_terminate(), events_terminate() and others in the right order. All modifications of console title are mutexed to allow tty code to obtain console window handle right. * exceptions.cc (exception_init): initialization of signal_arrived event moved to events_init(). (call_handler): raise signal arrived event after resuming main thread. (__cygwin_exception_handler): raise signal instead of calling ctrl_c_handler, because exception handler is called in a context of the thread, caused exception, and SuspendThread in call_handler blocks itself :-) (ctrl_c_handler): clear stopsig on SIGCONT delivery, call ResumeThread until suspend count > 1, notify parent about child's status changed. Care about handling SIGCONT signal. On stop signals release vital mutexes used by stopped thread, save signal number for wait(WUNTRACED) calls, notify parent about child's status change. Do not stop processes running without job control (when pgid == 0). Ensure that main thread is unblocked before call _exit(). (events_init): new (events_terminate): new * fcntl.cc (_fcntl): use saved open flags on F_GETFL/F_SETFL instead of game with access_ variable.

(hmap_init): take care on exec'ed processes. (init_std_file_from_handle): open /dev/tty for standard handles if tty usage enabled. (build_fhandler): check for tty slave and pty master devices. * include/exceptions.h: exception handler returns "int" (exception handling code), not "void". * include/termios.h: new defines, struct winsize must contain ws_xpixel and ws_ypixel members (commented now to avoid incompabilities with existing binaries. Should be uncommented in next release. * net.cc (gethostbyaddr): corrected return value * passwd.cc (parse): remove trailing newline from password lines (user's shell was reported with trailing newline before). * pinfo.cc (lock_pinfo_for_update): open mutex code moved to events_init() in exceptions.cc. (destroy_pinfo_lock): removed, pinfo_mutex is now closed in events_terminate() in exceptions.cc. (init_self): the initial value for pgid must be 0 (no job-controlled process). * select.cc: all debug_printf's changed to select_printf. (fd_pipe_map): new class to implement (polling...) select on pipes. (pipethread): new (cygwin32_select): comment out socket only case since generic code (select on different types of handles) works for sockets too but is interruptable. The case for always_ready_used is used now and for polling select (zero timevalue). Changes to support select on pipes. * shared.cc (shared_info::initialize): initialize tty table. * signal.cc (sleep/usleep/sigsuspend/pause): signal_arrived moved from u area to dll's address space, signal_arrived is manual reset event now. (_raise): implemented as kill (self, sig). (kill_worker): new. Use SendMessage instead of PostMessage to avoid some timing problems. * spawn.cc: include tty.h. (spawn_guts) call close_all_files() on exec, call tty_terminate() before process exit. Some changes due to moving signal_arrived to dll's address space. (_spawnve): inherit control tty number on spawn. * syscalls.cc (close_all_files): reenabled. The code is ok after all! The troubles were due to incorrect usage on exec() calls. (setsid): no longer a stub (ptsname): new * termios.cc: all syscall_printf's changed to termios_printf. (tcget(set)pgrp): rewritten, no longer a stub. * times.cc (utimes): It looks like Win32 does not allow changing times of directories, so just return success in this case. * tty.cc: new file (tty_init): new (tty_terminate): new (attach_tty): new (detach_tty): new (tty::init): new (tty_list::terminate): new (tty_list::connect_tty): new (tty_list::free_tty): new (tty_list::init): new (tty_list::allocate_tty): new (fhandler_tty_master::fhandler_tty_master): new (create_tty_master): new (fhandler_tty_master::init): new (doecho): new (do_input): new (process_input): new (do_output): new (process_output): new (process_ioctl): new (fhandler_tty_slave::fhandler_tty_slave): new (fhandler_tty_slave::open): new (fhandler_tty_slave::init): new (fhandler_tty_slave::close): new (fhandler_tty_slave::write): new (fhandler_tty_slave::read): new (fhandler_tty_slave::linearize): new (fhandler_tty_slave::de_linearize): new (fhandler_tty_slave::dup): new (fhandler_tty_slave::dup_for_fork): new (fhandler_tty_slave::fstat): new (fhandler_tty_slave::tcgetattr): new (fhandler_tty_slave::tcsetattr): new (fhandler_tty_slave::tcflush): new (fhandler_tty_slave::tcsetpgrp): new (fhandler_tty_slave::tcgetpgrp): new (fhandler_tty_slave::send_ioctl_request): new (fhandler_tty_slave::ioctl): new (fhandler_pty_master::fhandler_pty_master): new (fhandler_pty_master::fstat): new (fhandler_pty_master::open): new (fhandler_pty_master::close): new (fhandler_pty_master::write): new (fhandler_pty_master::read): new (fhandler_pty_master::tcgetattr): new (fhandler_pty_master::tcsetattr): new (fhandler_pty_master::tcflush): new (fhandler_pty_master::ioctl): new (fhandler_pty_master::ptsname): new (fhandler_pty_master::linearize): new (fhandler_pty_master::de_linearize): new (fhandler_pty_master::dup_for_fork): new (grantpt): new (unlockpt): new * tty.h: new * utils/ps.cc: display process's control tty number. * wait.cc (wait_for_single): removed.
