* * mount.h (fs_info::inited): New inline method.Corinna Vinschen2010-04-261-24/+29
| | | | | | | | | * path.cc (path_conv::check): Clear filesystem info if following a symlink. Use new fs_info::inited method to check if FS info is already available. (symlink_info::check): Drop fs_update_called. Use fs_info::inited method instead. Streamline test for leading space and trailing dot or space. Add comments.
* * path.h (get_nt_native_path): Add third parameter to declaration andCorinna Vinschen2010-04-231-28/+46
| | | | | | | | | | | | | | | | | | | | declare with regparms. * path.cc (get_nt_native_path): Add third parameter to allow conversion of leading and trailing dots and spaces on filesystems only supporting filenames following DOS rules. (path_conv::get_nt_native_path): Call get_nt_native_path according to fs.has_dos_filenames_only flag. (getfileattr): Accommodate new parameter to get_nt_native_path. (symlink_info::check): Revamp fs_update_called handling to call fs.update only once per call. Call get_nt_native_path according to fs.has_dos_filenames_only flag. Streamline filesystem dependent code not to be called more than once unnecessarily. Drop code tweaking incoming path for broken filesystems only allowing DOS pathnames. Rely on changed get_nt_native_path instead. * mount.cc (fillout_mntent): Accommodate new parameter to get_nt_native_path. * strfuncs.cc (tfx_rev_chars): New conversion table with comment. (sys_cp_wcstombs): Use tfx_rev_chars rather than tfx_chars.

| | | | | | | | | | | | | | | | | from mask. Expand the comment a bit. (WIN_FAT_FLAGS): New define. (FS_IS_WINDOWS_FAT): New macro. (fs_info::update): Handle remote FS faking to be FAT. Subsume under CIFS. Check for NWFS and has_buggy_basic_info only for remote filesystems. Add check for has_dos_filenames_only. * mount.h (class fs_info): Add has_dos_filenames_only status flag. Implement accessors. * path.cc (symlink_info::check): Rearrange variable definitions to clear them up. Add a restart label to allow a clean restart within the method. Add a check for broken filesystems only allowing DOS pathnames in case we encounter a STATUS_OBJECT_NAME_NOT_FOUND status. If all checks point to one of that, restart method with tweaked incoming path. Add lengthy comments to explain what we do.
