The Windows code is known to work fine using gcc. Use of MSVC is discouraged since there have been so many incompatible CRT version changes in such a short span of time. (Actually, use of Microsoft-anything is generally discouraged; the same OpenLDAP code is at least 2-3x faster on the same hardware when using Linux instead of Windows.) > Two problems solved in the patch: > 1. closedir()'s retval is used, thus it must not be void.

(ITS#6041) opendir() and closedir() bugs on Windows
by test.007＠seznam.cz 27 Mar '09

27 Mar '09

Full_Name: Test Seven Version: 2.4.15 OS: Windows URL: Submission from: (NULL) (195.113.184.20) Two problems solved in the patch: 1. closedir()'s retval is used, thus it must not be void. Windows uses implicit declaration ``int closedir(int)'' because the function is not declared in headers, thus the call in ldif.c compiles, but uses random value in EAX. 2. opendir() must set errno, because ldif_readdir() reads it. The patch converts the most common Windows error codes to errno codes after FindFirstFile() WinAPI call. The bugs prevent me from loading cn=config configuration. --- utils.c.orig 2009-01-22 01:00:58.000000000 +0100 +++ utils.c 2009-03-27 14:28:33.500000000 +0100 @@ -466,6 +466,40 @@ int mkstemp( char * template ) #endif #ifdef _MSC_VER +/* Equivalent of MS CRT's _dosmaperr(). + * @param lastError[in] Result of GetLastError(). + */ +static errno_t win2errno(DWORD lastError) +{ + const struct { + DWORD windows_code; + errno_t errno_code; + } WIN2ERRNO_TABLE[] = { + { ERROR_SUCCESS, 0 }, + { ERROR_FILE_NOT_FOUND, ENOENT }, + { ERROR_PATH_NOT_FOUND, ENOENT }, + { ERROR_TOO_MANY_OPEN_FILES, EMFILE }, + { ERROR_ACCESS_DENIED, EACCES }, + { ERROR_INVALID_HANDLE, EBADF }, + { ERROR_NOT_ENOUGH_MEMORY, ENOMEM }, + { ERROR_NOT_ENOUGH_MEMORY, ENOMEM }, + { ERROR_LOCK_VIOLATION, EACCES }, + { ERROR_FILE_EXISTS, EEXIST }, + { ERROR_INVALID_PARAMETER, EINVAL }, + { ERROR_FILENAME_EXCED_RANGE, ENAMETOOLONG }, + }; + const unsigned int WIN2ERRNO_TABLE_SIZE = sizeof(WIN2ERRNO_TABLE) / sizeof(WIN2ERRNO_TABLE[0]); + const errno_t DEFAULT_ERRNO_ERROR = -1; + unsigned int i; + + for (i = 0; i < WIN2ERRNO_TABLE_SIZE; ++i) { + if (WIN2ERRNO_TABLE[i].windows_code == lastError) { + return WIN2ERRNO_TABLE[i].errno_code; + } + } + return DEFAULT_ERRNO_ERROR; +} + struct dirent { char *d_name; }; @@ -493,9 +527,10 @@ DIR *opendir( char *path ) h = FindFirstFile( tmp, &data ); - if ( h == INVALID_HANDLE_VALUE ) + if ( h == INVALID_HANDLE_VALUE ) { + errno = win2errno(GetLastError()); return NULL; - + } d = ber_memalloc( sizeof(DIR) ); if ( !d ) return NULL; @@ -518,10 +553,11 @@ struct dirent *readdir(DIR *dir) } return &dir->data; } -void closedir(DIR *dir) +int closedir(DIR *dir) { FindClose(dir->dir); ber_memfree(dir); + return 0; } #endif
