(cwd_fixup_after_exec): New function. * path.h: Accomodate path.cc changes. * pinfo.cc (pinfo_init): Accept a pointer to an environment table. Pass this to environ_init.

* * winsup.h: Eliminate inclusion of most of the cygwin .h files. Use .h filesChristopher Faylor2000-08-221-1/+6
| | | | | only in sources which require them. * Makefile.in: Generate dependencies with -MD option.
* * cygerrno.h: New file. Use this throughout whenever errno manipulation isChristopher Faylor2000-08-221-0/+1
| | | | | | | | | | | | | | | 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 /.
* * winsup.h: Split out dtable definitions into separate header file.Christopher Faylor2000-08-121-0/+2
| | | | | | * dtable.h: New file. * sigproc.h: Eliminate pinfo.h usage here. Use it in source files that need it.
* Rename hinfo -> dtable. Name the former dtable array 'fdtab'.Christopher Faylor2000-08-121-48/+48

* * select.cc (allocfd_set): Zero allocated fd_set.Christopher Faylor2000-08-091-2/+2
| | | | | | | | | | | | | | (cygwin_select): Move fd_set copying logic from ::wait to here. Use common return through sell.poll. (select_stuff::wait): Just return success or failure and let caller fill in fd_set. * pinfo.h (pinfo): Eliminate self-referential pointer to sidbuf since pinfo structure exists at random locations now. * fork.cc (fork): Use 'use_psid' element to control when the psid is relevant. * shared.cc (sec_user): Ditto. * spawn.cc (spawn_guts): Ditto. * uinfo.cc (internal_getlogin): Ditto. * syscall.cc (seteuid): Ditto. Set use_psid element.
* * hinfo.cc (hinfo::find_unused_handle): Just check for table entry == NULLChristopher Faylor2000-08-041-1/+1
| | | | | | | since we are already bounds checked by default. * thread.cc (ResourceLocks::Lock): Streamline this function since it is called a lot. (ReleaseResourceLock): Ditto.
* * winsup.h: take out protections of environ, errno, allow C useDJ Delorie2000-08-021-1/+1
| | | | | | | | | | * *.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.
