#47831 [NEW]: Compile warning for strnlen() in main/spprintf.c (missing #define _GNU_SOURCE)

From: rainer dot jung at kippdata dot de Operating system: Linux PHP version: 5.2.9 PHP Bug Type: Compile Warning Bug description: Compile warning for strnlen() in main/spprintf.c (missing #define _GNU_SOURCE) Description: ------------ PHP 5.2.9 does auto detection for strnlen(). On Linux the detection results in strnlen() availability. The function is only available, when _GNU_SOURCE is defined though. File main/spprintf.c uses it without _GNU_SOURCE in PHP 5.2.9. This is due to an incomplete backport from MAIN and 5.3. See http://cvs.php.net/viewvc.cgi/php-src/main/spprintf.c?r1=1.25.2.2.2.10.2.4&r2=1.25.2.2.2.10.2.5 and http://cvs.php.net/viewvc.cgi/php-src/main/spprintf.c?r1=1.53&r2=1.54& and compare with http://cvs.php.net/viewvc.cgi/php-src/main/spprintf.c?r1=1.25.2.2.2.14&r2=1.25.2.2.2.15 Patch: --- main/spprintf.c 2009-02-04 16:03:12.000000000 +0100 +++ main/spprintf.c 2009-03-29 21:58:10.000000000 +0200 @@ -76,6 +76,7 @@ * SIO stdio-replacement strx_* functions by Panos Tsirigotis * <panos@alumni.cs.colorado.edu> for xinetd. */ +#define _GNU_SOURCE #include "php.h" #include <stddef.h> -- Edit bug report at http://bugs.php.net/?id=47831&edit=1 -- Try a CVS snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=47831&r=trysnapshot52 Try a CVS snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=47831&r=trysnapshot53 Try a CVS snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=47831&r=trysnapshot60 Fixed in CVS: http://bugs.php.net/fix.php?id=47831&r=fixedcvs Fixed in CVS and need be documented: http://bugs.php.net/fix.php?id=47831&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=47831&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=47831&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=47831&r=needscript Try newer version: http://bugs.php.net/fix.php?id=47831&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=47831&r=support Expected behavior: http://bugs.php.net/fix.php?id=47831&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=47831&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=47831&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=47831&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=47831&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=47831&r=dst IIS Stability: http://bugs.php.net/fix.php?id=47831&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=47831&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=47831&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=47831&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=47831&r=mysqlcfg
