* winsup.h: take out protections of environ, errno, allow C use * *.cc: put winsup.h before other headers (for __INSIDE_CYGWIN__); use cur_environ() instead of just environ * times.cc: remove import protections * glob.c: add winsup.h * localtime.c: ditto * smallprint.c: ditto * Makefile.in: don't __INSIDE_CYGWIN__ as it messes up profiling.

#include <sys/ioctl.h>
#include <errno.h>
* cygerrno.h: New file. Use this throughout whenever errno manipulation is required. * errno.cc: Use DWORD to hold Windows errors. (geterrno_from_win_error): New function. (seterrno_from_win_error): Use geterrno_from_win_error to convert supplied windows error (suggested by Corinna Vinschen). * path.cc (symlink_info): Add error element. * path.cc (path_conv::check): Remove errno setting. Use new symlink_info errno element to set path_conv error, where appropriate. (symlink_info::check): Set error element rather than attempting to manipulate errno. Add more checks for trailing / and /.. even though they are currently useless. Avoid setting EINVAL. * path.cc (normalize_posix_path): Correct check for trailing /.

#include "cygerrno.h"
Throughout, reorganize header file inclusion to put security.h prior to fhandler.h. * fhandler.h (fhandler_base::get_inheritance): New method. * fhandler_socket.cc (fhandler_socket::create_secret_event): Use proper close-on-exec inheritance when creating. (fhandler_socket::check_peer_secret_event): Create handle as non-inheritable.
2001-07-26 21:22:24 +02:00
#include "security.h"
* winsup.h: Eliminate inclusion of most of the cygwin .h files. Use .h files only in sources which require them. * Makefile.in: Generate dependencies with -MD option.
2000-08-22 07:10:20 +02:00
#include "fhandler.h"
Add "path.h" include throughout, where needed. Use new path_conv methods and operators to simplify testing for directory and attributes, throughout. * path.h (path_conv::exists): New method. (path_conv::has_attribute): Ditto. (path_conv::isdir): Ditto. (path_conv::DWORD &): New operator. (path_conv::int &): Ditto. * dir.cc (rmdir): Eliminate a goto. * dtable.cc (dtable::build_fhandler): Accept opt and suffix info for path_conv.check. Return fh == NULL on path_conv error. Pass unit to set_name as appropriate. (dtable::reset_unix_path_name): New method. * dtable.h (dtable): Declare new method. Reflect arg changes to build_fhandler. * fhandler.cc (fhandler_disk_dummy_name): Eliminate. (fhandler_base::set_name): Expect paths to be NULL. Build unix_path_name from win32_path_name when it is a device. (fhandler_base::reset_unix_path_name): New method. (fhandler_base::raw_read): Report EISDIR when ERROR_INVALID_FUNCTION or ERROR_INVALID_PARAMETER and reading a directory. (fhandler_disk_file::fstat): Don't call stat_dev since we should now never be calling fhandler_disk_file methods with devices. (fhandler_base::fhandler_base): Clear {unix,win32}_path_name. (fhandler_base::~fhandler_base): Always free {unix,win32}_path_name. (fhandler_disk_file::fhandler_disk_file): Remove set_no_free_names kludge. (fhandler_disk_file::open): Ditto. * fhandler.h (fhandler_base::no_free_names): Eliminate. (fhandler_base::set_no_free_names): Ditto. * fhandler_tty.cc (fhandler_tty_slave::fhandler_tty_slave): Don't set unix_path_name here. * path.cc (fchdir): Lock fd table throughout. Use new dtable::reset_unix_path_name method to reset path. * syscalls.cc (stat_worker): Reorganize to always call fstat method. Pass path_conv method to fhandler_*::open. (chroot): Elminate a goto.

#include "path.h"
* winsup.h: Eliminate inclusion of most of the cygwin .h files. Use .h files only in sources which require them. * Makefile.in: Generate dependencies with -MD option.
2000-08-22 07:10:20 +02:00
#include "dtable.h"
Throughout, change fdtab references to cygheap->fdtab. * child_info.h (cygheap_exec_info): Eliminate special fdtab stuff. * spawn.cc (spawn_guts): Ditto. * cygheap.cc (cygheap_init): Initialize fdtab, if appropriate. * cygheap.h (CYGHEAPSIZE): Include size of init_cygheap. (_cmalloc_entry): Include fdtab here. * dtable.h (dtable): Declare/define new methods. * dtable.cc (dtable::vfork_child_fixup): New method. (dtable::fixup_after_exec): Remove unneeded extra arguments. * dcrt0.cc (dll_crt0_1): Ditto. * environ.cc (getwinenv): Use case sensitive comparison. (winenv): Make a copy of environment cache to avoid realloc problems when duplicate environment variables exist in the environment. (From Egor Duda) * net.cc (cygwin_socket): Revert Apr 14 change. * include/sys/file.h: Protect against previous X_OK definition. * passwd.cc: Eliminate passwd_sem throughout. * security.cc: Ditto. * cygwin.din: Export New functions. * passwd.cc (read_etc_passwd): Make race safe. (getpwuid_r): New function. (getpwnam_r): New function.
2001-04-18 23:10:15 +02:00
#include "cygheap.h"
Split out tty and shared_info stuff into their own headers and use throughout. Include sys/termios.h for files which need it. * tty.h: New file. * shared_info.h: New file. * fhandler.h: Move inline methods that rely on tty stuff to fhandler_console.cc. * fhandler_tty.cc (fhandler_pty_master::process_slave_output): Set output_done_event immediately after reading data to speed up tty output processing. (process_output): Set write_error to errno or zero. (fhandler_tty_slave::write): Check previous write error prior to writing to slave end of pipe. This allows tty output to be slightly less synchronous. * fhandler_console.cc (fhandler_console::tcsetpgrp): Moved here from fhandler.h. (fhandler_console::set_input_state): Ditto.
