[patch] solaris getcwd() brokeness

Well all the fancy new streams code in 4.3.0 seems to tickle a Solaris issue with getcwd(). It seems that under certain cases solaris' getcwd() fails when other os' work. Consequently 4.3.0 causes a huge ammount of breakage for some sites running solaris. Below is a patch that seems to work around the problem. This may not be the best approach, but it was an attempt at a quick-fix so that 4.3.0 would be usable for now. This problem has bug number: #21310 [1]. Comments welcome. I'd like to commit this (or similar) before any more releases are made. -James <jflemer@php.net> [1] http://bugs.php.net/21310 ]] Patch sponsored by: The University of Vermont [[ Index: TSRM/tsrm_virtual_cwd.c =================================================================== RCS file: /repository/TSRM/tsrm_virtual_cwd.c,v retrieving revision 1.41 diff -u -b -u -r1.41 tsrm_virtual_cwd.c --- TSRM/tsrm_virtual_cwd.c 6 Nov 2002 18:07:22 -0000 1.41 +++ TSRM/tsrm_virtual_cwd.c 12 Feb 2003 04:39:11 -0000 @@ -303,7 +303,7 @@ return (0); #if !defined(TSRM_WIN32) && !defined(NETWARE) - if (IS_ABSOLUTE_PATH(path, path_length)) { + if (IS_ABSOLUTE_PATH(path, path_length) || (state->cwd_length < 1)) { if (use_realpath && realpath(path, resolved_path)) { path = resolved_path; path_length = strlen(path); @@ -363,6 +363,7 @@ } + if (state->cwd_length > 0 || IS_ABSOLUTE_PATH(path, path_length)) { ptr = tsrm_strtok_r(path_copy, TOKENIZER_STRING, &tok); while (ptr) { ptr_length = strlen(ptr); @@ -416,6 +417,11 @@ state->cwd[state->cwd_length+1] = '\0'; state->cwd_length++; } + } else { + state->cwd = (char *) realloc(state->cwd, path_length+1); + memcpy(state->cwd, path, path_length+1); + state->cwd_length = path_length; + } if (verify_path && verify_path(state)) { CWD_STATE_FREE(state); Index: main/main.c =================================================================== RCS file: /repository/php4/main/main.c,v retrieving revision 1.512.2.5 diff -u -b -u -r1.512.2.5 main.c --- main/main.c 16 Dec 2002 15:44:06 -0000 1.512.2.5 +++ main/main.c 12 Feb 2003 04:39:12 -0000 @@ -1507,7 +1507,11 @@ { zend_file_handle *prepend_file_p, *append_file_p; zend_file_handle prepend_file, append_file; +#ifdef VIRTUAL_DIR char *old_cwd; +#else + int old_cwd_fd; +#endif char *old_primary_file_path = NULL; int retval = 0; @@ -1515,9 +1519,11 @@ if (php_handle_special_queries(TSRMLS_C)) { return 0; } +#ifdef VIRTUAL_DIR #define OLD_CWD_SIZE 4096 old_cwd = do_alloca(OLD_CWD_SIZE); old_cwd[0] = '\0'; +#endif zend_try { #ifdef PHP_WIN32 @@ -1528,7 +1534,11 @@ if (primary_file->type == ZEND_HANDLE_FILENAME && primary_file->filename) { +#ifdef VIRTUAL_DIR VCWD_GETCWD(old_cwd, OLD_CWD_SIZE-1); +#else + old_cwd_fd = open(".", 0); +#endif VCWD_CHDIR_FILE(primary_file->filename); } @@ -1578,10 +1588,14 @@ } zend_end_try(); +#ifdef VIRTUAL_DIR if (old_cwd[0] != '\0') { VCWD_CHDIR(old_cwd); } free_alloca(old_cwd); +#else + fchdir(old_cwd_fd); +#endif return retval; } /* }}} */ Index: main/safe_mode.c =================================================================== RCS file: /repository/php4/main/safe_mode.c,v retrieving revision 1.51 diff -u -b -u -r1.51 safe_mode.c --- main/safe_mode.c 6 Nov 2002 18:07:23 -0000 1.51 +++ main/safe_mode.c 12 Feb 2003 04:39:12 -0000 @@ -121,6 +121,8 @@ VCWD_REALPATH(filename, path); *s = DEFAULT_SLASH; } else { + path[0] = '.'; + path[1] = '\0'; VCWD_GETCWD(path, sizeof(path)); } } /* end CHECKUID_ALLOW_ONLY_DIR */
