Karsten Blees	0217569bb2	Win32: Unicode file name support (dirent) Changes opendir/readdir to use Windows Unicode APIs and convert between UTF-8/UTF-16. Removes parameter checks that are already covered by xutftowcs_path. This changes detection of ENAMETOOLONG from MAX_PATH - 2 to MAX_PATH (matching is_dir_empty in mingw.c). If name + "/*" or the resulting absolute path is too long, FindFirstFile fails and errno is set through err_win_to_posix. Increases the size of dirent.d_name to accommodate the full WIN32_FIND_DATA.cFileName converted to UTF-8 (UTF-16 to UTF-8 conversion may grow by factor three in the worst case).

Karsten Blees	d8890ce726	Win32 dirent: improve dirent implementation Improve the dirent implementation by removing the relics that were once necessary to plug into the now unused MinGW runtime, in preparation for Unicode file name support. Move FindFirstFile to opendir, and FindClose to closedir, with the following implications: - DIR.dd_name is no longer needed - chdir(one); opendir(relative); chdir(two); readdir() works as expected (i.e. lists one/relative instead of two/relative) - DIR.dd_handle is a valid handle for the entire lifetime of the DIR struct - thus, all checks for dd_handle == INVALID_HANDLE_VALUE and dd_handle == 0 have been removed - the special case that the directory has been fully read (which was previously explicitly tracked with dd_handle == INVALID_HANDLE_VALUE && dd_stat != 0) is now handled implicitly by the FindNextFile error handling code (if a client continues to call readdir after receiving NULL, FindNextFile will continue to fail with ERROR_NO_MORE_FILES, to the same effect) - extracting dirent data from WIN32_FIND_DATA is needed in two places, so moved to its own method - GetFileAttributes is no longer needed. The same information can be obtained from the FindFirstFile error code, which is ERROR_DIRECTORY if the name is NOT a directory (-> ENOTDIR), otherwise we can use err_win_to_posix (e.g. ERROR_PATH_NOT_FOUND -> ENOENT). The ERROR_DIRECTORY case could be fixed in err_win_to_posix, but this probably breaks other functionality. Removes the ERROR_NO_MORE_FILES check after FindFirstFile (this was fortunately a NOOP (searching for '*' always finds '.' and '..'), otherwise the subsequent code would have copied data from an uninitialized buffer). Changes malloc to git support function xmalloc, so opendir will die() if out of memory, rather than failing with ENOMEM and letting git work on incomplete directory listings (error handling in dir.c is quite sparse).

Karsten Blees	a8248f4a8d	Win32 dirent: clarify #include directives Git-compat-util.h is two dirs up, and already includes <dirent.h> (which is the same as "dirent.h" due to -Icompat/win32 in the Makefile).

Erik Faye-Lund	d1b6e6e015	win32: use our own dirent.h The mingw-runtime implemenation of opendir, readdir and closedir sets errno to 0 on success, something that POSIX explicitly forbids. `3ba7a06` ("A loose object is not corrupt if it cannot be read due to EMFILE") introduce a dependency on this behaviour, leading to a broken "git clone" on Windows. compat/mingw.c contains an implementation of readdir, and compat/msvc.c contains implementations of opendir and closedir. Move these to compat/win32/dirent.[ch], and change to our own DIR structure at the same time. This provides a generic Win32-implementation of opendir, readdir and closedir which works on both MinGW and MSVC and does not reset errno, and as a result git clone is working again on Windows.
