From: yoarvi at gmail dot com Operating system: Solaris 10 (SPARC) PHP version: 6SVN-2009-11-16 (SVN) PHP Bug Type: Unicode Function Upgrades related Bug description: [PATCH] - unicode byte order difference between SPARC and x86
Description: ------------ zspprintf() incorrectly represents strings/chars as unicode characters on Solaris (SPARC). There are byte ordering differences for unicode representations between x86 and SPARC: For example, the unicode representation (i've grouped them in sets of 2chars) of '/tmp' on x86 is '/''\0' 't''\0' 'm''\0' 'p''\0' and on SPARC it is '\0''/' '\0''t' '\0''m' '\0''p' http://marc.info/?l=php-internals&m=125811990106419&w=2 has some more details. the problem seems to be in the smart_str_append2c macro that zspprintf()/xbuf_format_converter end up using. The following patch fixes the problem: Index: ext/standard/php_smart_str.h =================================================================== --- ext/standard/php_smart_str.h (revision 290471) +++ ext/standard/php_smart_str.h (working copy) @@ -86,10 +86,17 @@ smart_str_appendc_ex((dest), (c), 0) /* appending of a single UTF-16 code unit (2 byte)*/ +#if (defined(i386) || defined(__i386__) || defined(_X86_)) #define smart_str_append2c(dest, c) do { \ smart_str_appendc_ex((dest), (c&0xFF), 0); \ smart_str_appendc_ex((dest), (c&0xFF00 ? c>>8 : '\0'), 0); \ } while (0) +#else +#define smart_str_append2c(dest, c) do { \ + smart_str_appendc_ex((dest), (c&0xFF00 ? c>>8 : '\0'), 0); \ + smart_str_appendc_ex((dest), (c&0xFF), 0); \ +} while (0) +#endif #define smart_str_free(s) \ smart_str_free_ex((s), 0) Reproduce code: --------------- % sapi/cli/php ext/spl/tests/DirectoryIterator_getBasename_basic_test.php Expected result: ---------------- getBasename_test Actual result: -------------- php goes into an infinite loop -- Edit bug report at http://bugs.php.net/?id=50189&edit=1 -- Try a snapshot (PHP 5.2): http://bugs.php.net/fix.php?id=50189&r=trysnapshot52 Try a snapshot (PHP 5.3): http://bugs.php.net/fix.php?id=50189&r=trysnapshot53 Try a snapshot (PHP 6.0): http://bugs.php.net/fix.php?id=50189&r=trysnapshot60 Fixed in SVN: http://bugs.php.net/fix.php?id=50189&r=fixed Fixed in SVN and need be documented: http://bugs.php.net/fix.php?id=50189&r=needdocs Fixed in release: http://bugs.php.net/fix.php?id=50189&r=alreadyfixed Need backtrace: http://bugs.php.net/fix.php?id=50189&r=needtrace Need Reproduce Script: http://bugs.php.net/fix.php?id=50189&r=needscript Try newer version: http://bugs.php.net/fix.php?id=50189&r=oldversion Not developer issue: http://bugs.php.net/fix.php?id=50189&r=support Expected behavior: http://bugs.php.net/fix.php?id=50189&r=notwrong Not enough info: http://bugs.php.net/fix.php?id=50189&r=notenoughinfo Submitted twice: http://bugs.php.net/fix.php?id=50189&r=submittedtwice register_globals: http://bugs.php.net/fix.php?id=50189&r=globals PHP 4 support discontinued: http://bugs.php.net/fix.php?id=50189&r=php4 Daylight Savings: http://bugs.php.net/fix.php?id=50189&r=dst IIS Stability: http://bugs.php.net/fix.php?id=50189&r=isapi Install GNU Sed: http://bugs.php.net/fix.php?id=50189&r=gnused Floating point limitations: http://bugs.php.net/fix.php?id=50189&r=float No Zend Extensions: http://bugs.php.net/fix.php?id=50189&r=nozend MySQL Configuration Error: http://bugs.php.net/fix.php?id=50189&r=mysqlcfg
