* First steps toward native path handling.Kaz Kylheku2017-11-161-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | - /proc and /dev are are still available, accessed as proc:/ and dev:/ - All other paths are native, and do not "see" virtual Cygwin items; /cygdrive is just C:\cygdrive (if the current drive is C). - chdir() to a virtual directory like dev:/ or proc:/ results in errno EOPNOTSUPP. * winsup/cygwin/mount.cc (mount_info::conv_to_win32_path): Takes new bool argument, hide_cygwin_virtuals. If true all that the function does is "backslashify" the path. (mount_info::add_item): Special hack inserted here so that we can create the virtual root directory which holds dev and proc and whatnot, and is passed here as "/". We cannot let this go through normalize_posix_path any more because it will turn to C:\. * winsup/cygwin/mount.h (mount_info::conv_to_win32_path): Declaration updated. * winsup/cygwin/path.cc (is_posix_space): New static function: tests for paths in special spaces, currently "dev:/" and "proc:/". Used by normalize_posix_path. (normalize_posix_path): Any path that doesn't satisfy the is_posix_space test is treated as Win32. Since the bulk of the code is now only used for these spaces, the relative path handling is not required and a the corresponding block of code is removed. Paths satisfying is_posix_space are transformed. I.e. the underlying path resolution machine in the path_conv class still recognizes /proc and /dev. It's just that these will not occur, because normalize_posix_path will convert them to references with drive names. (path_conv::check): Pass the is_msdos flag down to mount_info::conv_to_win32_path as the new argument. Thus if normalize_posix_path indicates a native path, this function will hide the virtual spaces. Also, we add PATH_NOPOSIX and PATH_NOACL to the object's path_flags. This is used in chdir. (normalize_win32_path): A small piece of logic works against our plan here: it checks for the leading forward slash on the path, and prevents such paths from being converted to Win32 paths with a drive reference. We eliminate this test, and treat paths unconditionally. (chdir): Here, if the path is not native, we return EOPNOTSUPP. Thus it is impossible to chdir into Cygwin virtual directories like /dev (now referenced as dev:/). They can be listed but not turned into the current directory. Eventually we want chdir to actually set the Win32 current directory of the process; that can't work for virtual dirs. * winsup/cygwin/path.h (path_conv::is_native): New inline accessor which tests for the PATH_NOPOSIX flag.
* More secure way of obtaining command interpreter.Kaz Kylheku2017-11-161-0/+1
| | | | | | | | | | | | | | | | | | Instead of relying on the COMSPEC environment variable, what we can do is assume that the program is called "cmd.exe", and then look for it in the directory reported by the GetSystemDirectoryA Win32 function in kernel32.dll. * winsup/cygwin/path.h (get_cmd_exe_path): New function declared. * winsup/cygwin/spawn.cc (av::setup): Use get_cmd_exe_path instead of getenv("COMSPEC"). (cmd_exe_path): New static variable. (init_cmd_exe_path): New static function. (get_cmd_exe_path): New function. * winsup/cygwin/syscalls.cc (system, getusershell, popen): Use get_cmd_exe_path instead of getenv("COMSPEC").
* cygwin: unify reparse point checking code into single functionCorinna Vinschen2017-07-241-1/+2
| | | | | | | | | | | | | | | | | So far we had two functions checking the content of a reparse point, readdir_check_reparse_point in fhandler_disk_file.cc for the sake of readdir, and symlink_info::check_reparse_point for the sake of generic path checking. * Rename check_reparse_point_target helper to check_reparse_point_string and convert to static function. * Create new check_reparse_point_target helper containing the core reparse point checking code * Just call check_reparse_point_target from readdir_check_reparse_point and symlink_info::check_reparse_point and only perform the unique task in those functions.

* Handle up to 63 partitions per driveCorinna Vinschen2016-06-231-1/+5
| | | | | | | | | | | | | | Revamp device parsing code. Introducing support for more partitions into the shilka-generated parser has the unfortunate side-effect of raising the size of the DLL by almost 2 Megs. Therefore we split out the handling for /dev/sdXY devices into a tiny bit of hand-written code. While at it, remove some unused cruft from devices.* and generally clean up the device class to provide access methods instead of direct access to members.

* Improve encapsulation of FS type behind path_conv coverCorinna Vinschen2016-06-211-3/+24
| | | | | | | | | | | Rather than having to check for the FS type in the caller and having to call different functions whether FS is NFS or not, encapsulate the info in path_conv_handle/path_conv methods to allow FS type agnostic calling from upper level functions. This patch only implements the methods. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
