(mount_info::read_v1_mounts): New function. Given a regkey, read the mounts in the old v1 registry layout corresponding to the key.

Controlled by chunksize global variable. Thu Jan 7 22:02:18 1999 Christopher Faylor patch from Corinna Vinschen : * utils/passwd.c: New file. * utils/Makefile.in: Add dependencies for passwd. * syscalls.cc (chmod): Change permission checking in case of readonly test. (stat_dev): Change default permission bits to allow writing for all users. (chown): Retry LookupAccountName with username set to domain\\username, if returned SID-Type is not SidTypeUser. Thu Jan 7 17:50:49 1999 Christopher Faylor * fhandler.cc (fhandler_base::set_name): Fix bug which disallowed '%' in a file name. Thu Jan 7 00:21:41 1999 Geoffrey Noer * path.cc: Add comments. * path.h: Correct file description comment. Tue Jan 5 16:07:15 1999 Christopher Faylor * fhandler_serial.cc (fhandler_serial::raw_read): Be more defensive about not calling problematic functions when the overlapped I/O is armed. Reset the overlapped event prior to calling read or suffer an "operation aborted". * select.cc (peek_serial): Ditto. Mon Jan 4 15:16:22 1999 Geoffrey Noer Eliminate warnings: * utils/mount.cc (show_mounts): make format a const char *. * utils/ps.cc (main): make literal strings const char *s. * utils/cygpath.cc (long_options): cast literal strings to char *s. (main): Sun Jan 3 20:46:12 1999 Christopher Faylor * select.cc (peek_console): Remove #if 0 around NT code workaround. Sat Jan 2 00:04:01 1999 Christopher Faylor * Makefile.in: Remove include directories made obsolete by recent changes to mmap.cc. Also remove libraries that appear to be unnecessary for linking. * mkvers.sh: Put contents of .snapshot-date, if available, into the DLL. Fri Jan 1 22:44:49 1999 Christopher Faylor * fhandler.h (fhandler_serial): Add flag to track state of overlapped serial I/O. Add overlapped_setup method for common setup of overlapped structure. * fhandler_serial.cc (fhandler_serial::overlapped_setup): New method. Sets up the overlapped structure for overlapped serial I/O. (fhandler_serial::raw_read): Use overlapped_armed flag to avoid calling functions which perform overlapped operations if overlapped I/O is in already progress. This should only be the case if a previous operation was interrupted or select has detected serial I/O. (fhandler_serial::open): Use overlapped_setup. (fhandler_serial::fixup_after_fork): Ditto. (fhandler_serial::de_linearize): Ditto. (fhandler_serial::dup): Ditto. (fhandler_serial::tcsetattr): Fix typo which caused IGNPAR to be ignored. * hinfo.cc (hinfo::select_read): Set saw_error to zero explicitly to avoid spurious reporting of select errors. (hinfo::select_write): Ditto. (hinfo::select_except): Ditto. * select.cc (peek_serial): Use overlapped_armed to avoid calling functions which perform overlapped operations if overlapped I/O is already in progress.
